Remus Lupin Book #3

COMPILED BY WILLOW SEVERN willowsevern@yahoo.com

Harry, Ron, and Hermione set off down the corridor, looking for an empty compartment, but all were full except for the one at the very end of the train.

This had only one occupant, a man sitting fast asleep next to the window. Harry, Ron, and Hermione checked on the threshold. The Hogwarts Express was usually reserved for students and they had never seen an adult there before, except for the witch who pushed the food cart.

The stranger was wearing an extremely shabby set of wizard's robes that had been darned in several places. He looked ill and exhausted. Though quite young, his light brown hair was flecked with gray.

"Who d'you reckon he is?" Ron hissed as they sat down and slid the door shut, taking the seats farthest away from the window.

"Professor R. J. Lupin," whispered Hermione at once.

"How d'you know that?"

"It's on his case," she replied, pointing at the luggage rack over the man's head, where there was a small, battered case held together with a large quantity of neatly knotted string. The name Professor R. J. Lupin was stamped across one corner in peeling letters.

"Wonder what he teaches?" said Ron, frowning at Professor Lupin's pallid profile.

"That's obvious," whispered Hermione. "There's only one vacancy, isn't there? Defense Against the Dark Arts."

Harry, Ron, and Hermione had already had two Defense Against the Dark Arts teachers, both of whom had lasted only one year. There were rumors that the job was jinxed.

"well, I hope he's up to it," said Ron doubtfully. "He looks like on, good hex would finish him off, doesn't he? Anyway..." He turned to Harry. "What were you going to tell us?"

Chapter: 5

"Stick it back in the trunk," Harry advised as the Sneakoscope whistled piercingly, "or it'll wake him up."

He nodded toward Professor Lupin. Ron stuffed the Sneakoscope into a particularly horrible pair of Uncle Vernon's old socks, which deadened the sound, then closed the lid of the trunk on it.

Chapter: 5

At one o'clock, the plump witch with the food cart arrived at the compartment door.
"D'you think we should wake him up?" Ron asked awkwardly, nodding toward Professor Lupin. "He looks like he could do with some food."
Hermione approached Professor Lupin cautiously.
"Er - Professor?" she said. "Excuse me - Professor?"
He didn't move.
"Don't worry dear," said the wirch as she handed Harry a large stack of Cauldron Cakes. "If he's hungry when he wakes, I'll be up front with the driver."
"I suppose he is asleep?" said Ron quietly as the witch slid the compartment door closed. "I mean - he hasn't died, has he?"
No, no, he's breathing," whispered Hermione, taking the Cauldron Cake Harry passed her.
He might not be very good company, but Professor Lupin's presence in their compartment had its uses. Midafternoon, just as it had started to rain, blurring the rolling hills outside the window, they heard footsteps in the corridor again, and their three least favorite people appeared at the door: Draco Malfoy, flanked by his cronies, Vincent Crabbe and Gregory Goyle.

Chapter: 5

Ron stood up so quickly he knocked Crookshanks's basket to the floor. Professor Lupin gave a snort.

"Who's that?" said Malfoy, taking an automatic step backward as he spotted Lupin.

"New teacher," said Harry, who got to his feet, too, in case he needed to hold Ron back. "What were you saying, Malfoy?"

Malfoy's pale eyes narrowed; he wasn't fool enough to pick a fight right under a teacher's nose.

Chapter: 5

Ron made a violent gesture in midair.

"Ron," hissed Hermione, pointing at Professor Lupin, "be careful..."

But Professor Lupin was still fast asleep.

The rain thickened as the train sped yet farther north; the windows were now a solid, shimmering gray, which graduily darkened until lanterns flickered into life all along the corridors and over the luggage racks. The train rattled, the rain hammered, the ind roared, but still, Professor Lupin slept.

"We must be nearly there," said Ron, leaning forward to look past Professor Lupin at the now completely black window.

The words had hardly left him when the train started to slow down.

"Great," said Ron, getting up and walking carefully past Professor Lupin to try and see outside. "I'm starving. I want to get to the feast...."

Chapter: 5

"Not here!" said Harry hurriedly. "I'm here!"

"Ouch!" said Neville.

"Quiet!" said a hoarse voice suddenly.

Professor Lupin appeared to have woken up at last. Harry could hear movements in his corner.

None of them spoke.

There was a soft, crackling noise, and a shivering light filled the compartment. Professor Lupin appeared to be holding a handful of flames. They illuminated his tired, gray face, but his eyes looked alert and wary.

"Stay where you are," he said in the same hoarse voice, and he got slowly to his feet with his handful of fire held out in front of him.

But the door slid slowly open before Lupin could reach it.

Standing in the doorway, illuminated by the shivering flames in Lupin's hand, was a cloaked figure that towered to the ceiling. Its face was completely hidden beneath its hood. Harry's eyes darted downward, and what he saw made his stomach contract. There was a hand protruding from the cloak and it was glistening, grayish, slimy-looking, and scabbed, like something dead that had decayed in water...

Chapter: 5

Harry opened his eyes; there were lanterns above him, and the floor was shaking -- the Hogwarts Express was moving again and the lights had come back on. He seemed to have slid out of his seat onto the floor. Ron and Hermione were kneeling next to him, and above them he could see Neville and Professor Lupin watching. Harry felt very sick; when he put up his hand to push his glasses back on, he felt cold sweat on his face.

Chapter: 5

"But I heard screaming --"

A loud snap made them all jump. Professor Lupin was breaking an enormous slab of chocolate into pieces.

"Here," he said to Harry, handing him a particularly large piece. "Eat it. It'll help."

Harry took the chocolate but didn't eat it.

"What was that thing?" he asked Lupin.

"A dementor," said Lupin, who was now giving chocolate to everyone else. "One of the dementors of Azkaban."

Everyone stared at him. Professor Lupin crumpled up the empty chocolate wrapper and put it in his pocket.

"Eat," he repeated. "It'll help. I need to speak to the driver, excuse me...

He strolled past Harry and disappeared into the corridor.

Chapter: 5

"And Professor Lupin stepped over you, and walked toward the dementor, and pulled out his wand," said Hermione, "and he said, 'None of us is hiding Sirius Black under our cloaks. Go.' But the dementor didn't move, so Lupin muttered something, and a silvery thing shot out of his wand at it, and it turned around and sort of glided away.... "

Chapter: 5

Professor Lupin had come back. He paused as he entered, looked around, and said, with a small smile, "I haven't poisoned that chocolate, you know...."

Harry took a bite and to his great surprise felt warmth spread suddenly to the tips of his fingers and toes.

"We'll be at Hogwarts in ten minutes," said Professor Lupin. "Are you all right, Harry?"

Harry didn't ask how Professor Lupin knew his name.

"Fine," he muttered, embarrassed.

Chapter: 5

"Did you faint as well, Weasley?" said Malfoy loudly. "Did the scary old dementor frighten you too, Weasley?"

"Is there a problem?" said a mild voice. Professor Lupin had just gotten out of the next carriage.

Malfoy gave Professor Lupin an insolent stare, which took in the patches on his robes and the delapidated suitcase. With a tiny hint of sarcasm in his voice, he said, "Oh, no -- er -- Professor," then he smirked at Crabbe and Goyle and led them up the steps into the castle.

Chapter: 5

Once they were in her office, a small room with a large, welcoming fire, Professor McGonagall motioned Harry and Hermione to sit down. She settled herself behind her desk and said abruptly, "Professor Lupin sent an owl ahead to say that you were taken ill on the train, Potter."

Chapter: 5

"Well, he should have some chocolate, at the very least," said Madam Pomfrey, who was now trying to peer into Harry's eyes.

"I've already had some," said Harry. "Professor Lupin gave me some. He gave it to all of us."

"Did he, now?" said Madam Pomfrey approvingly. "So we've finally got a Defense Against the Dark Arts teacher who knows his remedies?"

Chapter: 5

"On a happier note," he continued, I am pleased to welcome two new teachers to our ranks this year.

"First, Professor Lupin, who has kindly consented to fill the post of Defense Against the Dark Arts teacher."

There was some scattered, rather unenthusiastic applause. Only those who had been in the compartment on the train with Professor Lupin clapped hard, Harry among them. Professor Lupin looked particularly shabby next to all the other teachers in their best robes.

"Look at Snape!" Ron hissed in Harry's ear.

Professor Snape, the Potions master, was staring along the staff table at Professor Lupin. It was common knowledge that Snape ,anted the Defense Against the Dark Arts job, but even Harry, who hated Snape, was startled at the expression twisting his thin, sallow face. it was beyond anger: it was loathing. Harry knew that expression only too well; it was the look Snape wore every time he set eyes on Harry.

"As to our second new appointment," Dumbledore continued as the lukewarm applause for Professor Lupin died away. "Well, I am sorry to tell you that Professor Kettleburn, our Care of Magical Creatures teacher, retired at the end of last year in order to enjoy more time with his remaining limbs. However, I am delighted to say that his place will be filled by none other than Rubeus Hagrid, who has agreed to take on this teaching job in addition to his gamekeeping duties."

Chapter: 5

Professor Lupin wasn't there when they arrived at his first Defense Against the Dark Arts lesson. They all sat down, took out their books, quills, and parchment, and were talking when he finally entered the room. Lupin smiled vaguely and placed his tatty old briefcase on the teacher's desk. He was as shabby as ever but looked healthier than he had on the train, as though he had had a few square meals.

"Good afternoon," he said. "Would you please put all your books back in your bags. Today's will be a practical lesson. You will need only your wands."

A few curious looks were exchanged as the class put away their books. They had never had a practical Defense Against the Dark Arts before, unless you counted the memorable class last year when their old teacher had brought a cageful of pixies -to class and set them loose.

"Right then," said Professor Lupin, when everyone was ready. "If you'd follow me."

Puzzled but interested, the class got to its feet and followed Professor Lupin out of the classroom. He led them along the deserted corridor and around a corner, where the first thing they saw was Peeves the Poltergeist, who was floating upside down in midair and stuffing the nearest keyhole with chewing gum.

Peeves didn't look up until Professor Lupin was two feet away; ,hen he wiggled his curly-toed feet and broke into song.

"Loony, loopy Lupin," Peeves sang. "Loony, loopy Lupin, loony, loopy Lupin --"

Rude and unmanageable as he almost always was, Peeves usually showed some respect toward the teachers. Everyone looked quickly at Professor Lupin to see how he would take this; to their surprise, he was still smiling.

"I'd take that gum out of the keyhole if I were you, Peeves," he said pleasantly. "Mr. Filch won't be able to get in to his brooms."

Filch was the Hogwarts caretaker, a bad-tempered, failed wizard who waged a constant war against the students and, indeed, Peeves. However, Peeves paid no attention to Professor Lupin's words, except to blow a loud wet raspberry.

Professor Lupin gave a small sigh and took out his wand.

"This is a useful little spell," he told the class over his shoulder. "Please watch closely."

He raised the wand to shoulder height, said, "Waddiwasi! "and pointed it at Peeves.

With the force of a bullet, the wad of chewing gum shot out of the keyhole and straight down Peeves's left nostril; he whirled upright and zoomed away, cursing.

"Cool, sir!" said Dean Thomas in amazement.

"Thank you, Dean," said Professor Lupin, putting his wand away again. "Shall we proceed?"

They set off again, the class looking at shabby Professor Lupin with increased respect. He led them down a second corridor and stopped, right outside the staffroom door.

"Inside, please," said Professor Lupin, opening it and standing back.

The staffroom, a long, paneled room full of old, mismatched chairs, was empty except for one teacher. Professor Snape was sitting in a low armchair, and he looked around as the class filed in. His eyes were glittering and there was a nasty sneer playing around his mouth. As Professor Lupin came in and made to close the door behind him, Snape said, "Leave it open, Lupin. I'd rather not witness this."

He got to his feet and strode past the class, his black robes billowing behind him. At the doorway he turned on his heel and said, "Possibly no one's warned you, Lupin, but this class contains Neville Longbottom. I would advise you not to entrust him with anything difficult. Not unless Miss Granger is hissing instructions in his ear."

Neville went scarlet. Harry glared at Snape; it was bad enough that he bullied Neville in his own classes, let alone doing it in front of other teachers.

Professor Lupin had raised his eyebrows.

"I was hoping that Neville would assist me with the first stage of the operation," he said, "and I am sure he will perform it admirably."

Neville's face went, if possible, even redder. Snape's lip curled, but he left, shutting the door with a snap.

"Now, then," said Professor Lupin, beckoning the class toward the end of the room, where there was nothing but an old wardrobe where the teachers kept their spare robes. As Professor Lupin went to stand next to it, the wardrobe gave a sudden wobble, banging off the wall.

"Nothing to worry about," said Professor Lupin calmly because a few people had jumped backward in alarm. "There's a boggart in there."

Most people seemed to feel that this was something to worry about. Neville gave Professor Lupin a look of pure terror, and Seamus Finnigan eyed the now rattling doorknob apprehensively.

"Boggarts like dark, enclosed spaces," said Professor Lupin. "Wardrobes, the gap beneath beds, the cupboards under sinks -- I've even met one that had lodged itsself in a grandfather clock. This one moved in yesterday afternoon, and I asked the headmaster if the staff would leave it to give my third years some practice.

"So, the first question we must ask ourselves is, what is a boggart?"

Hermione put up her hand.

"It's a shape-shifter," she said. "It can take the shape of whatever it thinks will frighten us most."

"Couldn't have put it better myself," said Professor Lupin, and Hermione glowed. "So the boggart sitting in the darkness within has not yet assumed a form. He does not yet know what will frighten the person on the other side of the door. Nobody knows what a boggart looks like when he is alone, but when I let him out, he will immediately become whatever each of us most fears.

"This means," said Professor Lupin, choosing to ignore Neville's small sputter of terror, "that we have a huge advantage over the boggart before we begin. Have you spotted it, Harry?"

Trying to answer a question with Hermione next to him, bobbing up and down on the balls of her feet with her hand in the air, was very off-putting, but Harry had a go.

"Er -- because there are so many of us, it won't know what shape it should be?"

"Precisely," said Professor Lupin, and Hermione put her hand down, looking a little disappointed. "It's always best to have com pany when you're dealing with a boggart. He becomes confused. Which should he become, a headless corpse or a flesh-eating slug? I once saw a boggart make that very mistake -- tried to frighten two people at once and turned himself into half a slug. Not remotely frightening.

"The charm that repels a boggart is simple, yet it requires force of mind. You see, the thing that really finishes a boggart is laughter. What you need to do is force it to assume a shape that you find amusing.

"We will practice the charm without wands first. After me, please ... Riddikulus!"

"Riddikulus!" said the class together.

"Good," said Professor Lupin. "Very good. But that was the easy part, I'm afraid. You see, the word alone is not enough. And this is where you come in, Neville."

The wardrobe shook again, though not as much as Neville, who walked forward as though he were heading for the gallows.

"Right, Neville," said Professor Lupin. "First things first: what would you say is the thing that frightens you most in the world?"

Neville's lips moved, but no noise came out.

"didn't catch that, Neville, sorry," said Professor Lupin cheerfully.

Neville looked around rather wildly, as though begging someone to help him, then said, in barely more than a whisper, "Professor Snape."

Nearly everyone laughed. Even Neville grinned apologetically. Professor Lupin, however, looked thoughtful.

"Professor Snape... hmmm... Neville, I believe you live with your grandmother?"

"Er -- yes," said Neville nervously. "But -- I don't want the boggart to turn intoo her either."

"No, no, you misunderstand me," said Professor Lupin, now smiling. "I wonder, could you tell us what sort of clothes your grandmother usually wears?"

Neville looked startled, but said, "Well... always the same hat. A tall one with a stuffed vulture on top. And a long dress... green, normally... and sometimes a fox-fur scarf."

"And a handbag?" prompted Professor Lupin.

"A big red one," said Neville.

"Right then," said Professor Lupin. "Can you picture those clothes very clearly, Neville? Can you see them in your mind's eye?"

"Yes," said Neville uncertainty, plainly wondering what was coming next.

"When the boggart bursts out of this wardrobe, Neville, and sees You, it will assume the form of Professor Snape," said Lupin. "And You will raise your wand -- thus -- and cry 'Riddikulus' -- and concentrate hard on your grandmother's clothes. If all goes well, Professor Boggart Snape will be forced into that vulture-topped hat, and that green dress, with that big red handbag."

There was a great shout of laughter. The wardrobe wobbled more violently.

"If Neville is successful, the boggart is likely to shift his attention to each of us in turn," said Professor Lupin. "I would like all of you to take a moment now to think of the thing that scares you most, and imagine how you might force it to look comical...."

The room went quiet. Harry thought... 'What scared him most in the world?

His first thought was Lord Voldemort -- a Voldemort returned to full strength. But before he had even started to plan a possible counterattack on a boggart-Voldemort, a horrible image came floating to the surface of his mind....

A rotting, glistening hand, slithering back beneath a black cloak ... a long, rattling breath from an unseen mouth... then a cold so penetrating it felt like drowning....

Harry shivered, then looked around, hoping no one had noticed. Many people had their eyes shut tight. Ron was muttering to himself, "Take its legs off " Harry was sure he knew what that was about. Ron's greatest fear was spiders.

"Everyone ready?" said Professor Lupin.

Harry felt a lurch of fear. He wasn't ready. How could you make a dementor less frightening? But he didn't want to ask for more time; everyone else was nodding and rolling up their sleeves.

"Neville, we're going to back away," said Professor Lupin. "Let you have a clear field, all right? I'll call the next person forward.... Everyone back, now, so Neville can get a clear shot --"

They all retreated, backed against the walls, leaving Neville alone beside the wardrobe. He looked pale and frightened, but he had pushed up the sleeves of his robes and was holding his wand ready.

"On the count of three, Neville," said Professor Lupin, who was

pointing his own wand at the handle of the wardrobe. "One two -- three -- now!"

A jet of sparks shot from the end of Professor Lupin's wand and hit the doorknob. The wardrobe burst open. Hook-nosed and menacing, Professor Snape stepped out, his eyes flashing at Neville.

Neville backed away, his wand up, mouthing wordlessly. Snape was bearing down upon him, reaching inside his robes.

"R -- r -- riddikulus! "squeaked Neville.

There was a noise like a whip crack. Snape stumbled; he was wearing a long, lace-trimmed dress and a towering hat topped with a moth-eaten vulture, and he was swinging a huge crimson handbag.

There was a roar of laughter; the boggart paused, confused, and Professor Lupin shouted, "Parvati! Forward!"

Parvati walked forward, her face set. Snape rounded on her. There was another crack, and where he had stood was a bloodstained, bandaged mummy; its sightless face was turned to Parvati and it began to walk toward her very slowly, dragging its feet, its stiff arms rising --

"Riddikulus!" cried Parvati.

A bandage unraveled at the mummy's feet; it became entangled, fell face forward, and its head rolled off.

"Seamus!" roared Professor Lupin.

Seamus darted past Parvati.

Crack! Where the mummy had been was a woman with floorlength black hair and a skeletal, green-tinged face -- a banshee. She opened her mouth wide and an unearthly sound filled the room, a long, wailing shriek that made the hair on Harry's head stand on end -- 'Riddikulus!" shouted Seamus.

The banshee made a rasping noise and clutched her throat; her voice was gone.

Crack! The banshee turned into a rat, which chased its tail in a circle, then -- crack!- became a rattlesnake, which slithered and writhed before -- crack! -- becoming a single, bloody eyeball.

'It's confused!" shouted Lupin. "We're getting there! Dean!"

Dean hurried forward.

Crack! The eyeball became a severed hand, which flipped over and began to creep along the floor like a crab.

"Riddikulus!" yelled Dean.

'There was a snap, and the hand was trapped in a mousetrap.

"Excellent! Ron, you next!"

Ron leapt forward.

Crack!

Quite a few people screamed. A giant spider, six feet tall and covered in hair, was advancing on Ron, clicking its pincers menacingly. For a moment, Harry thought Ron had frozen. Then --

"Riddikulus!" bellowed Ron, and the spider's legs vanished; it rolled over and over; Lavender Brown squealed and ran out of its way and it came to a halt at Harry's feet. He raised his wand, ready, but --

"Here!" shouted Professor Lupin suddenly, hurrying forward. Crack!

The legless spider had vanished. For a second, everyone looked wildly around to see where it was. Then they saw a silvery-white orb hanging in the air in front of Lupin, who said, "Riddikulus!" almosi lazily.

Crack!

"Forward, Neville, and finish him off!" said Lupin as the boggart landed on the floor as a cockroach. Crack! Snape was back. This time Neville charged forward looking determined.

"Riddikulus!" he shouted, and they had a split second's view of Snape in his lacy dress before Neville let out a great "Ha!" of laughter, and the boggart exploded, burst into a thousand tiny wisps of smoke, and was gone.

"Excellent!" cried Professor Lupin as the class broke into applause. "Excellent) Neville. Well done, everyone.... Let me See... five points to Gryffindor for every person to tackle the boggart -- ten for Neville because he did it twiice... and five each to Hermione and Harry."

"But I didn't do anything," said Harry.

"You and Hermione answered my questions correctly at the start of the class, Harry," Lupin said lightly. "Very well, everyone, an excellent lesson. Homework, kindly read the chapter on boggarts and summarize it for me... to be handed in on Monday. That will be all."

Talking excitedly, the class left the staffroom. Harry, however, wasn't feeling cheerful. Professor Lupin had deliberately stopped him from tackling the boggart. Why? Was it because he'd seen Harry collapse on the train, and thought he wasn't up to much? Had he thought Harry would pass out again?

But no one else seemed to have noticed anything.

"Did you see me take that banshee?" shouted Seamus. "And the hand!" said Dean, waving his own around.

"And Snape in that hat!" "And my mummy!"

I wonder why Professor Lupin's frightened of crystal balls?" said Lavender thoughtfully.

"That was the best Defense Against the Dark Arts lesson we've ever had, wasn't it?" said Ron excitedly as they made their way back to the classroom to get their bags.

"He seems like a very good teacher," said Hermione approvingly. "But I wish I could have had a turn with the boggart --"

Chapter: 7

In no time at all, Defense Against the Dark Arts had become most people's favorite class. Only Draco Malfoy and his gang of Slytherins had anything bad to say about Professor Lupin.

"Look at the state of his robes," Malfoy would say in a loud whisper as Professor Lupin passed. "He dresses like our old houseelf "

But no one else cared that Professor Lupin's robes were patched and frayed. His next few lessons were just as interesting as the first. After boggarts, they studied Red Caps, nasty little goblin like creatures that lurked wherever there had been bloodshed: in the dungeons of castles and the potholes of deserted battlefields, waiting to bludgeon those who had gotten lost. From Red Caps they moved on to kappas, creepy. water-dwellers that looked like scaly monkeys, with webbed hands itching to strangle unwitting waders in their ponds.

Harry only wished he was as happy with some of his other classes. Worst of all was Potions. Snape was in a particularly vindictive mood these days, and no one was in any doubt why. The story of the boggart assuming Snape's shape, and the way that Neville had dressed it in his grandmother's clothes, had traveled through the school like wildfire. Snape didn't seem to find it funny. His eyes flashed menacingly at the very mention of Professor Lupin's name, and he was bullying Neville worse than ever.

Chapter: 8

But Harry didn't go back to the common room; he climbed a staircase, thinking vaguely of visiting the Owlery to see Hedwig, and was walking along another corridor when a voice from inside one of the rooms said, "Harry?"

Harry doubled back to see who had spoken and met Professor Lupin, looking around his office door.

"What are you doing?" said Lupin, though in a very different voice from Filch. "Where are Ron and Hermione?"

"Hogsmeade," said Harry, in a would-be casual voice.

"Ah," said Lupin. He considered Harry for a moment. "Why don't you come in? I've just taken delivery of a grindylow for our next lesson." "A what?" said Harry. I

He followed Lupin into his office. In the corner stood a very large tank of water. A sickly green creature with sharp little horns had its face pressed against the glass, pulling faces and flexing its long, spindly fingers.

"Water demon," said Lupin, surveying the grindylow thoughtfully. "We shouldn't have much difficulty with him, not after the kappas. The trick is to break his grip. You notice the abnormally long fingers? Strong, but very brittle."

The grindylow bared its green teeth and then buried itself in a tangle of weeds in a corner.

"Cup of tea?" Lupin said, looking around for his kettle. "I was just thinking of making one."

"All right," said Harry awkwardly.

Lupin tapped the kettle with his wand and a blast of steam issued suddenly from the spout.

"Sit down," said Lupin, taking the lid off a dusty tin. "I've only got teabags, I'm afraid -- but I daresay you've had enough of tea leaves?"

Harry looked at him. Lupin's eyes were twinkling.

"How did you know about that?" Harry asked.

"Professor McGonagall told me," said Lupin, passing Harry a chipped mug of tea. "You're not worried, are you?"

"No," said Harry.

He thought for a moment of telling Lupin about the dog he'd seen in Magnolia Crescent but decided not to. He didn't want Lupin to think he was a coward, especially since Lupin alreadv seemed to think he couldn't cope with a boggart.

Something of Harry's thoughts seemed to have shown on his face, because Lupin said, "Anything worrying you, Harry?"

"No," Harry lied. He drank a bit of tea and watched the grindylow brandishing a fist at him. "Yes," he said suddenly, putting his tea down on Lupin's desk. "You know that day we fought the boggart?"

"Yes," said Lupin slowly.

"Why didn't you let me fight it?" said Harry abruptly.

Lupin raised his eyebrows.

"I would have thought that was obvious, Harry," he said, sounding surprised.

Harry, who had expected Lupin to deny that he'd done any such thing, was taken aback.

"Why?" he said again.

"Well," said Lupin, frowning slightly, "I assumed that if the boggart faced you, it would assume the shape of Lord Voldemort."

Harry stared. Not only was this the last answer he'd expected, but Lupin had said Voldemort's name. The only person Harry had ever heard say the name aloud (apart from himself) was Professor Dumbledore.

"Clearly, I was wrong," said Lupin, still frowning at Harry. "But I didn't think it a good idea for Lord Voldemort to materialize in the staffroom. I imagined that people would panic."

"I didn't think of Voldemort," said Harry honestly. "I -- I remembered those dementors."

"I see," said Lupin thoughtfully. "Well, well... I'm impressed." fie smiled slightly at the look of surprise on Harry's face. "That suggests that what you fear most of all is -- fear. Very wise, Harry."

Harry didn't know what to say to that, so he drank some mot,, tea.

"So you've been thinking that I didn't believe you capable of fighting the boggart?" said Lupin shrewdly.

"Well... yeah," said Harry. He was suddenly feeling a lot happier. "Professor Lupin, you know the dementors --"

He was interrupted by a knock on the door.

"Come in," called Lupin.

The door opened, and in came Snape. He was carrying a goblet, which was smoking faintly, and stopped at the sight of Harry, his black eyes narrowing.

"Ah, Severus," said Lupin, smiling. "Thanks very much. Could you leave it here on the desk for me?"

Snape set down the smoking goblet, his eyes wandering between Harry and Lupin.

"I was just showing Harry my grindylow," said Lupin pleasantly, pointing at the tank.

"Fascinating," said Snape, without looking at it. "You should drink that directly, Lupin."

"Yes, Yes, I will," said Lupin.

"I made an entire cauldronful," Snape continued. "If you need more.

"I should probably take some again tomorrow. Thanks very much, Severus."

"Not at all," said Snape, but there was a look in his eye Harry didn't like. He backed out of the room, unsmiling and watchful.

Harry looked curiously at the goblet. Lupin smiled.

"Professor Snape has very kindly concocted a potion for me," he said. "I have never been much of a potion-brewer and this one is particularly complex." He picked up the goblet and sniffed it. "Pity sugar makes it useless," he added, taking a sip and shuddering.

"Why --?" Harry began. Lupin looked at him and answered the unfinished question.

"I've been feeling a bit off-color," he said. "This potion is the only thing that helps. I am very lucky to be working alongside Professor Snape; there aren't many wizards who are up to making it."

Professor Lupin took another sip and Harry had a crazy urge to knock the goblet out of his hands.

"Professor Snape's very interested in the Dark Arts, he blurted out.

"Really?" said Lupin, looking only mildly interested as he took another gulp of potion.

"Some people reckon --" Harry hesitated, then plunged recklessly on, "some people reckon he'd do anything to get the Defense Against the Dark Arts job."

Lupin drained the goblet and pulled a face.

"Disgusting," he said. "Well, Harry, I'd better get back to work. see you at the feast later."

"Right," said Harry, putting down his empty teacup.

The empty goblet was still smoking.

Chapter: 8

"What did you do?" said Hermione, looking anxious. "Did you get any work done?"

"No," said Harry. "Lupin made me a cup of tea in his office. And then Snape came in...."

He told them all about the goblet. Ron's mouth fell open.

"Lupin drank it?" he gasped. "Is he mad?"

Hermione checked her watch.

"We'd better go down, you know, the feast'll be starting in fiveminutes They hurried through the portrait hole and into the crowd, still discussing Snape.

"But if he -- you know" -- Hermione dropped her voice, glancing nervously around -- "if he was trying to to poison Lupin -- he wouldn't have done it in front of Harry."

Chapter: 8

The food was delicious; even Hermione and Ron, who were full to bursting with Honeydukes sweets, managed second helpings of everything. Harry kept glancing at the staff table. Professor Lupin looked cheerful and as well as he ever did; he was talking animatedly to tiny little Professor Flitwick, the Charms teacher. Harry moved his eyes along the table, to the place where Snape sat. Was he imagining it, or were Snape's eyes flickering toward Lupin more often than was natural?

Chapter: 8

Dumbledore took one quick look at the ruined painting and turned, his eyes somber, to see Professors McGonagall, Lupin, and Snape hurrying toward him.

Chapter: 8

Harry skidded to a halt outside the Defense Against the Dark Arts classroom, pulled the door open, and dashed inside.

"Sorry I'm late, Professor Lupin. I --"

But it wasn't Professor Lupin who looked up at him from the teacher's desk; it was Snape.

"This lesson began ten minutes ago, Potter, so I think we'll make it ten points from Gryffindor. Sit down."

But Harry didn't move.

"Where's Professor Lupin?" he said.

"He says he is feeling too ill to teach today," said Snape with a twisted smile. "I believe I told you to sit down?"

But Harry stayed where he was.

"What's wrong with him?"

Snape's black eyes glittered.

"Nothing life-threatening," he said, looking as though he wished it were. "Five more points from Gryffindor, and if I have to ask you to sit down again, it will be fifty."

Harry walked slowly to his seat and sat down. Snape looked around at the class.

"As I was saying before Potter interrupted, Professor Lupin has not left any record of the topics you have covered so far --"

"Please, sir, we've done boggarts, Red Caps, kappas, and grindylows," said Hermione quickly, "and we're just about to start --"

"Be quiet," said Snape coldly. "I did not ask for information. I was merely commenting on Professor Lupin's lack of organization."

"He's the best Defense Against the Dark Arts teacher we've ever had," said Dean Thomas boldly, and there was a murmur of agreement from the rest of the class. Snape looked more menacing than ever.

"You are easily satisfied. Lupin is hardly overtaxing you -- I ,Would expect first years to be able to deal with Red Caps and grindylows. Today we shall discuss --"

Harry watched him flick through the textbook, to the very back chapter, which he must know they hadn't covered.

"Werewolves," said Snape.

"But, sir," said Hermione, seemingly unable to restrain herself, "we're not supposed to do werewolves yet, we're due to start hinkypunks --"

"Miss Granger," said Snape in a voice of deadly calm, "I was under the impression that I am teaching this lesson, not you. And I am telling you all to turn to page 394." He glanced around again. 'All of you! Now!"

With many bitter sidelong looks and some sullen muttering, the class opened their books.

"Which of you can tell me how we distinguish between the werewolf and the true wolf?" said Snape.

Everyone sat in motionless silence; everyone except Hermione, whose hand, as it so often did, had shot straight into the air.

"Anyone?" Snape said, ignoring Hermione. His twisted smile was back. "Are you telling me that Professor Lupin hasn't even taught you the basic distinction between --"

"We told you," said Parvati suddenly, "we haven't got as far as werewolves yet, we're still on --"

"Silence!" snarled Snape. "Well, well, well, I never thought I'd meet a third-year class who wouldn't even recognize a werewolf when they saw one. I shall make a point of informing Professor Dumbledore how very behind you all are...."

"Please, sir," said Hermione, whose hand was still in the air, "the werewolf differs from the true wolf in several small ways. The snout of the werewolf --"

"That is the second time you have spoken out of turn, Miss Granger," said Snape coolly. "Five more points from Gryffindor for being an insufferable know-it-all."

Chapter: 9

No one made a sound throughout the rest of the lesson. They sat and made notes on werewolves from the textbook, while Snape prowled up and down the rows of desks, examining the work they had been doing with Professor Lupin.

"Very poorly explained... That is incorrect, the kappa is more commonly found in Mongolia.... Professor Lupin gave this eight out of ten? I wouldn't have given it three...."

Chapter: 9

"Snape's never been like this with any of our other Defense Against the Dark Arts teachers, even if he did want the job," Harry said to Hermione. "Why's he got it in for Lupin? D'you think this is all because of the boggart?"

"I don't know," said Hermione pensively. "But I really hope Professor Lupin gets better soon...."

Chapter: 9

"If Snape's teaching Defense Against the Dark Arts again, I'm skiving off," said Ron as they headed toward Lupin's classroom after lunch. "Check who's in there, Hermione."

Hermione peered around the classroom door.

"It's okay!"

Professor Lupin was back at work. It certainly looked as though he had been ill. His old robes were hanging more loosely on him and there were dark shadows beneath his eyes; nevertheless, he smiled at the class as they took their seats, and they burst at once into an explosion of complaints about Snape's behavior while Lupin had been ill.

"It's not fair, he was only filling in, why should he give us homework?"

"We don't know anything about werewolves two rolls of parchment!"

"Did you tell Professor Snape we haven't covered them yet?" Lupin asked, frowning slightly.

The babble broke out again.

"Yes, but he said we were really behind he wouldn't listen --"

"-- two rolls of parchment!"

Professor Lupin smiled at the look of indignation on every face.

"Don't worry. I'll speak to Professor Snape. You don't have to do the essay."

"Oh no," said Hermione, looking very disappointed. "I've already finished it!"

They had a very enjoyable lesson. Professor Lupin had brought along a glass box containing a hinkypunk, a little one-legged creature who looked as though he were made of wisps of smoke, rather frail and harmless looking.

"Lures travelers into bogs," said Professor Lupin as they took notes. "You notice the lantern dangling from his hand? Hops ahead -people follow the light -- then --"

The hinkypunk made a horrible squelching noise against the glass.

When the bell rang, everyone gathered up their things and headed for the door, Harry among them, but --

"Wait a moment, Harry," Lupin called. "I'd like a word."

Harry doubled back and watched Professor Lupin covering the hinkypunk's box with a cloth.

"I heard about the match," said Lupin, turning back to his desk and starting to pile books into his briefcase, "and I'm sorry about your broomstick. Is there any chance of fixing it?"

"No," said Harry. "The tree smashed it to bits."

Lupin sighed.

"They planted the Whomping Willow the same year that I arrived at Hogwarts. People used to play a game, trying to get near enough to touch the trunk. In the end, a boy called Davey Gudgeon nearly lost an eye, and we were forbidden to go near it. No broomstick would have a chance."

"Did you hear about the dementors too?" said Harry with difficulty.

Lupin looked at him quickly.

"Yes, I did. I don't think any of us have seen Professor Dumbledore that angry. They have been growing restless for some time -- furious at his refusal to let them inside the grounds.... I suppose they were the reason you fell?"

"Yes," said Harry. He hesitated, and then the question he had to ask burst from him before he could stop himself." Why? Why do they affect me like that? Am I just --?"

"It has nothing to do with weakness," said Professor Lupin sharply, as though he had read Harry's mind. "The dementors affect you worse than the others because there are horrors in your past that the others don't have."

A ray of wintery sunlight fell across the classroom, illuminating Lupin's gray hairs and the lines on his young face.

"Dementors are among the foulest creatures that walk this earth. They infest the darkest, filthiest places, they glory in decay and despair, they drain peace, hope, and happiness out of the air around them. Even Muggles feel their presence, though they can't see them. Get too near a dementor and every good feeling, every happy memory will be sucked out of you. If it can, the dementor will feed on you long enough to reduce you to something like itself... soul-less and evil. You'll be left with nothing but the worst experiences of your life. And the worst that happened to you, Harry, is enough to make anyone fall off their broom. You have nothing to feel ashamed of."

"When they get near me --" Harry stared at Lupin's desk, his throat tight. "I can hear Voldemort murdering my mum."

Lupin made a sudden motion with his arm as though to grip Harry's shoulder, but thought better of it. There was a moment's Silence, then --

"Why did they have to come to the match?" said Harry bitterly.

"They're getting hungry," said Lupin coolly, shutting his briefcase with a snap. "Dumbledore won't let them into the school, so their supply of human prey has dried up.... I don't think they could resist the large crowd around the Quidditch field. All that excitement ... emotions running high... it was their idea of a feast."

"Azkaban must be terrible," Harry muttered. Lupin nodded grimly.

"The fortress is set on a tiny island, way out to sea, but they don't need walls and water to keep the prisoners in, not when they're all trapped inside their own heads, incapable of a single cheery thought. Most of them go mad within weeks."

"But Sirius Black escaped from them," Harry said slowly. "He got away..."

Lupin's briefcase slipped from the desk; he had to stoop quickly to catch it.

"Yes," he said, straightening up, "Black must have found a way to fight them. I wouldn't have believed it possible.... Dementors are supposed to drain a wizard of his powers if he is left with them too long...."

"You made that dementor on the train back off," said Harry suddenly.

"There are -- certain defenses one can use," said Lupin. "But there was only one dementor on the train. The more there are, the more difficult it becomes to resist."

"What defenses?" said Harry at once. "Can you teach me?"

"I don't pretend to be an expert at fighting dementors, Harry, quite the contrary..."

"But if the dementors come to another Quidditch match, I need to be able to fight them --"

Lupin looked into Harry's determined face, hesitated, then said, "Well... all right. I'll try and help. But it'll have to wait until next term, I'm afraid. I have a lot to do before the holidays. I chose a very inconvenient time to fall ill."

What with the promise of anti-dementor lessons from Lupin, the thought that he might never have to hear his mother's death again, and the fact that Ravenclaw flattened Hufflepuff in their Quidditch match at the end of November, Harry's mood took a definite upturn. Gryffindor were not out of the running after all, although they could not afford to lose another match. Wood became repossessed of his manic energy, and worked his team as hard as ever in the chilly haze of rain that persisted into December. Harry saw no hint of a dementor within the grounds. Dumbledore's anger seemed to be keeping them at their stations at the entrances.

Chapter: 10

"I can't believe this," Harry muttered, running a hand along the Firebolt, while Ron sank onto Harry's bed, laughing his head off at the thought of Malfoy. "Who -?"

"I know," said Ron, controlling himself, "I know who it could've been -- Lupin!"

"What?" said Harry, now starting to laugh himself "Lupin? Listen, if he had this much gold, he'd be able to buy himself some new robes."

"Yeah, but he likes you," said Ron. "And he was away when your Nimbus got smashed, and he might've heard about it and decided to visit Diagon Alley and get this for you --"

"What d'you mean, he was away?" said Harry. "He was ill when I was playing in that match."

"Well, he wasn't in the hospital wing," said Ron. "I was there, cleaning out the bedpans on that detention from Snape, remember?"

Harry frowned at Ron.

"I can't see Lupin affording something like this."

Chapter: 11

Professor Trelawney ignored her. Eyes open again, she looked around once more and said, "But where is dear Professor Lupin?"

"I'm afraid the poor fellow is ill again," said Dumbledore, indicating that everybody should start serving themselves. "Most unfortunate that it should happen on Christmas Day."

"But surely you already knew that, Sibyll?" said Professor McGonagall, her eyebrows raised.

Chapter: 11

Professor Trelawney's voice suddenly became a good deal less misty.

"If you must know, Minerva, I have seen that poor Professor Lupin will not be with us for very long. He seems aware, himself, that his time is short. He positively fled when I offered to crystal gaze for him --"

"Imagine that," said Professor McGonagall dryly.

I doubt," said Dumbledore, in a cheerful but slightly raised voice, which put an end to Professor McGonagall and Professor Trelawney's conversation, "that Professor Lupin is in any immediate danger. Severus, you've made the potion for him again?"

"Yes, Headmaster," said Snape.

"Good," said Dumbledore. "Then he should be up and about in no time..."

Chapter: 11

"I'm working on it," said Harry quickly. "Professor Lupin said he'd train me to ward off the dementors. We should be starting this week. He said he'd have time after Christmas."

"Ah," said Wood, his expression clearing. "Well, in that case -- I really didn't want to lose you as Seeker, Harry. And have you ordered a new broom yet?"

Chapter: 12

It was Defense Against the Dark Arts that Harry was keen to get to; after his conversation with Wood, he wanted to get started on his anti-dementor lessons as soon as possible.

"Ah yes," said Lupin, when Harry reminded him of his promise at the end of class. "Let me see... how about eight o'clock on Thursday evening? The History of Magic classroom should be large enough.... I'll have to think carefully about how we're going to do this.... We can't bring a real dementor into the castle to practice on...."

"Still looks ill, doesn't he?" said Ron as they walked down the corridor, heading to dinner. "What d'you reckon's the matter with him?"

There was a loud and impatient "tuh" from behind them. It was Hermione, who had been sitting at the feet of a suit of armor, repacking her bag, which was so full of books it wouldn't close.

"And what are you tutting at us for?" said Ron irritably.

"Nothing," said Hermione in a lofty voice, heaving her bag back over her shoulder.

"Yes, you were," said Ron. "I said I wonder what's wrong with Lupin, and you --"

"Well, isn't it obvious?" said Hermione, with a look of maddening superiority.

Chapter: 12

At eight o'clock on Thursday evening, Harry left Gryffindor Tower for the History of Magic classroom. It was dark and empty when he arrived, but he lit the lamps with his wand and had waited only five minutes when Professor Lupin turned up, carrying a large packing case, which he heaved onto Professor Binn's desk.

"What's that?" said Harry.

"Another boggart," said Lupin, stripping off his cloak. "I've been combing the castle ever since Tuesday, and very luckily, I found this one lurking inside Mr. Filch's filing cabinet. It's the nearest we'll get to a real dementor. The boggart will turn into a dementor when he sees you, so we'll be able to practice on him. I can store him in my office when we're not using him; there's a cupboard under my desk he'll like."

"Okay," said Harry, trying to sound as though he wasn't apprehensive at all and merely glad that Lupin had found such a good substitute for a real dementor.

"So..." Professor Lupin had taken out his own wand, and indicated that Harry should do the same. "The spell I am going to try and teach you is highly advanced magic, Harry -- well beyond ordinary Wizarding Level. It is called the Patronus Charm."

"How does it work?" said Harry nervously.

"Well, when it works correctly, It conjures up a Patronus," said Lupin, "which is a kind of anti- dementor -- a guardian that acts as a shield between you and the dementor."

Harry had a sudden vision of himself crouching behind a Hagridsized figure holding a large club. Professor Lupin continued, "The Patronus is a kind of positive force, a projection of the very things that the dementor feeds upon -- hope, happiness, the desire to survive -- but it cannot feel despair, as real humans can, so the dementors can't hurt it. But I must warn you, Harry, that the charm might be too advanced for you. Many qualified wizards have difficulty with it."

"What does a Patronus look like?" said Harry curiously.

"Each one is unique to the wizard who conjures it."

"And how do you conjure it?"

"With an incantation, which will work only if you are concentrating, with all your might, on a single, very happy memory."

Harry cast his mind about for a happy memory. Certainly, nothing that had happened to him at the Dursleys' was going to do. Finally, he settled on the moment when he had first ridden a broomstick.

"Right," he said, trying to recall as exactly as possible the wonderful, soaring sensation of his stomach.

"The incantation is this --" Lupin cleared his throat. "Expecto patronum!"

"Expecto patronum, " Harry repeated under his breath, "expecto patronum."

"Concentrating hard on your happy memory?"

"Oh -- yeah --" said Harry, quickly forcing his thoughts back to that first broom ride. "Expecto patrono -- no, patronum -- sorry -- expecto patronum, expecto paatronum"

Something whooshed suddenly out of the end of his wand; it looked like a wisp of silvery gas.

"Did you see that?" said Harry excitedly. "Something happened!"

"Very good," said Lupin, smiling. "Right, then -- ready to try it on a dementor?"

"Yes," Harry said, gripping his wand very tightly, and moving into the middle of the deserted classroom. He tried to keep his mind on flying, but something else kept intruding.... Any second now, he might hear his mother again... but he shouldn't think that, or he would hear her again, and he didn't want to... or did he?

Lupin grasped the lid of the packing case and pulled.

A dementor rose slowly from the box, its hooded face turned toward Harry, one glistening, scabbed hand gripping its cloak. The lamps around the classroom flickered and went out. The dementor stepped from the box and started to sweep silently toward Harry, drawing a deep, rattling breath. A wave of piercing cold broke over him --

"Expecto patronum!" Harry yelled. "Expecto patronum! Expecto --"

But the classroom and the dementor were dissolving.... Harry was failing again through thick white fog, and his mother's voice was louder than ever, echoing inside his head -- "Not Harry! Not Harry! please -- I'll do anything!"

"Stand aside. Stand aside, girl!"

"Harry!"

Harry jerked back to life. He was lying flat on his back on the floor. The classroom lamps were alight again. He didn't have to ask what had happened.

"Sorry," he muttered, sitting up and feeling cold sweat trickling down behind his glasses.

"Are you all right?" said Lupin.

"Yes..." Harry pulled himself up on one of the desks and leaned against it.

"Here --" Lupin handed him a Chocolate Frog. "Eat this before we try again. I didn't expect you to do it your first time; in fact, I would have been astounded if you had."

"It's getting worse," Harry muttered, biting off the Frog's head. "I could hear her louder that time -- and him -- Voldemort

Lupin looked paler than usual. ,

"Harry, if you don't want to continue, I will more than understand --"

"I do!" said Harry fiercely, stuffing the rest of the Chocolate Frog into his mouth. "I've got to! What if the dementors turn up at our match against Ravenclaw? I can't afford to fall off again. If we lose this game we've lost the Quidditch Cup!"

"All right then... " said Lupin. "You might want to select 'other memory, a happy memory, I mean, to concentrate on.... That one doesn't seem to have been strong enough...."

Harry thought hard and decided his feelings when Gryffindor had won the House Championship last year had definitely qualified as very happy. He gripped his wand tightly again and took up his position in the middle of the classroom.

"Ready?" said Lupin, gripping the box lid.

"Ready," said Harry; trying hard to fill his head with happy thoughts about Gryffindor winning, and not dark thoughts about what was going to happen when the box opened.

"Go!" said Lupin, pulling off the lid. The room went icily cold and dark once more. The dementor glided forward, drawing its breath; one rotting hand was extending toward Harry -

"Expecto patronum!" Harry yelled. "Expecto patronum! Expecto Pat --"

White fog obscured his senses... big, blurred shapes were moving around him... then came a new voice, a man's voice, shouting, panicking --

"Lily, take Harry and go! It's him! Go! Run! I'll hold him off --"

The sounds of someone stumbling ftom a room -- a door bursting open -- a cackle of high- pitched laughter --

"Harry! Harry... wake up...."

Lupin was tapping Harry hard on the face. This time it was a minute before Harry understood why he was lying on a dusty classroom floor.

"I heard my dad," Harry mumbled. "That's the first time I've ever heard him -- he tried to take on Voldemort himself, to give my mum time to run for it...."

Harry suddenly realized that there were tears on his face mingling with the sweat. He bent his face as low as possible, wiping them off on his robes, pretending to do up his shoelace, so that Lupin wouldn't see.

"You heard James?" said Lupin in a strange voice.

"Yeah..." Face dry, Harry looked up. "Why -- you didn't know my dad, did you?"t;

"I -- I did, as a matter of fact," said Lupin. "We were friends at Hogwarts. Listen, Harry -- perhaps we should leave it here for tonight. This charm is ridiculously advanced.... I shouln't have suggested putting you through this...."

"No!" said Harry. He got up again. "I'll have one more go! I'm not thinking of happy enough things, that's what it is.... Hang on...."

He racked his brains. A really, really happy memory... one that he could turn into a good, strong Patronus...

The moment when he'd first found out he was a wizard, and would be leaving the Dursleys for Hogwarts! If that wasn't a happy memory, he didn't know what was.... Concentrating very hard on how he had felt when he'd realized he'd be leaving Privet Drive, Harry got to his feet and faced the packing case once more.

"Ready?" said Lupin, who looked as though he were doing this against his better judgment. "Concentrating hard? All right -- go!"

He pulled off the lid of the case for the third time, and the dementor rose out of it; the room fell cold and dark

'EXPECTO PATRONUM!" Harry bellowed. "EXPECTO PATRONUM! EXPECTO PATRONUM! "

The screaming inside Harry's head had started again -- except this time, it sounded as though it were coming from a badly tuned radio -- softer and louder and softer again -- and he could still see the dementor -- it had halted -- and then a huge, silver shadow came bursting out of the end of Harry's wand, to hover between him and the dementor, and though Harry's legs felt like water, he was still on his feet -- though for how much longer, he wasn't sure --

"Riddikulus!" roared Lupin, springing forward.

There was a loud crack, and Harry's cloudy Patronus vanished along with the dementor; he sank into a chair, feeling as exhausted as if he'd just run a mile, and felt his legs shaking. Out of the corner of his eye, he saw Professor Lupin forcing the boggart back into the packing case with his wand; it had turned into a silvery orb again.

"Excellent!" Lupin said, striding over to where Harry sat. "Excellent, Harry! That was definitely a start!"

"Can we have another go? Just one more go?"

"Not now," said Lupin firmly. "You've had enough for one night. Here --"

He handed Harry a large bar of Honeydukes' best chocolate.

"Eat the lot, or Madam Pomfrey will be after my blood. Same time next week?"

"Okay," said Harry. He took a bite of the chocolate and watched Lupin extinguishing the lamps that had rekindled with the disappearance of the dementor. A thought had just occurred to him.

"Professor Lupin?" he said. "If you knew my dad, you must've known Sirius Black as well."

Lupin turned very quickly.

"What gives you that idea?" he said sharply.

"Nothing -- I mean, I just knew they were friends at Hogwarts too...."

Lupin's face relaxed.

"Yes, I knew him," he said shortly. "Or I thought I did. You'd better be off, Harry, it's getting late."

Harry left the classroom, walking along the corridor and around a corner, then took a detour behind a suit of armor and sank down on its plinth to finish his chocolate, wishing he hadn't mentioned Black, as Lupin was obviously not keen on the subject. Then Harry's thoughts wandered back to his mother and father...

Chapter: 12

Ravenclaw played Slytherin a week after the start of term. Slytherin won, though narrowly. According to Wood, this was good news for Gryffindor, who would take second place if they beat Ravenclaw too. He therefore increased the number of team practices to five a leek. This meant that with Lupin's anti-dementor classes, which in themselves were more draining than six Quidditch practices, Harry had just one night a week to do all his homework. Even so, he was showing the strain nearly as much as Hermione, whose immense workload finally seemed to be getting to her. Every night, without fail, Hermione was to be seen in a corner of the common room, several tables spread with books, Arithmancy charts, rune dictionaries, diagrams of Muggles lifting heavy objects, and file upon file of extensive notes; she barely spoke to anybody and snapped when she was interrupted.

Chapter: 12

"You're expecting too much of yourself," said Professor Lupin, sternly in their fourth week of practice. "For a thirteen-year-old wizard, even an indistinct Patronus is a huge achievement. You aren't passing out anymore, are you?"

I thought a Patronus would -- charge the dementors down or something," said Harry dispiritedly. "Make them disappear --"

"The true Patronus does do that," said Lupin. "But you've achieved a great deal in a very short space of time. If the dementors put in an appearance at your next Quidditch match, You will be able to keep them at bay long enough to get back to the ground."

"You said it's harder if there are loads of them," said Harry.

"I have complete confidence in you," said Lupin, smiling. "Here -- you've earned a drink - something from the Three Broomsticks. You won't have tried it before --"

He pulled two bottles out of his briefcase.

"Butterbeer!" said Harry, without thinking. "Yeah, I like that stuff!"

Lupin raised an eyebrow.

"Oh -Ron and Hermione brought me some back from Hogsmeade," Harry lied quickly.

I see," said Lupin, though he still looked slightly suspicious. "Well -- let's drink to a Gryffindor victory against Ravenclaw! Not that I'm supposed to take sides, as a teacher... " he added hastily

They drank the butterbeer in silence, until Harry voiced something he'd been wondering for a while.

"What's under a dementor's hood?"

Professor Lupin lowered his bottle thoughtfully.

"Hmmm... well, the only people who really know are in no condition to tell us. You see, the dementor lowers its hood only to use its last and worst weapon."

"What's that?"

"They call it the Dementor's Kiss," said Lupin, with a slightly twisted smile. "It's what dementors do to those they wish to destroy utterly. I suppose there must be some kind of mouth under there, because they clamp their jaws upon the mouth of the victim and -- and suck out his soul."

Harry accidentally spat out a bit of butterbeer.

"What -- they kill --?"

"Oh no," said Lupin. "Much worse than that. You can exist without your soul, you know, as long as your brain and heart are still working. But you'll have no sense of self anymore, no memory, no. .. anything. There's no chance at all of recovery. You'll just exist. As an empty shell. And your soul is gone forever... lost."

Lupin drank a little more butterbeer, then said, "It's the fate that awaits Sirius Black. It was in the Daily Prophet this morning. The Ministry have given the dementors permission to perform it if they find him."

Harry sat stunned for a moment at the idea of someone having their soul sucked out through their mouth. But then he thought of Black.

"He deserves it," he said suddenly.

"You think so?" said Lupin lightly. "Do you really think anyone deserves that?"

"Yes," said Harry defiantly. "For... for some things..."

He would have liked to have told Lupin about the conversation he'd overheard about Black in the Three Broomsticks, about Black betraying his mother and father, but it would have involved revealing that he'd gone to Hogsmeade without permission, and he knew Lupin wouldn't be very impressed by that. So he finished his butterbeer, thanked Lupin, and left the History of Magic classroom.

Chapter: 12

"Oh, well -- you know -- working hard," said Hermione. Close-up, Harry saw that she looked almost as tired as Lupin.

Chapter: 12

Harry took off his black school robes, removed his wand from his pocket, and stuck it inside the T-shirt he was going to wear under his Quidditch robes. He only hoped he wouldn't need it. He wondered suddenly whether Professor Lupin was in the crowd, watching.

Chapter: 13

"That was quite some Patronus," said a voice in Harry's ear.

Harry turned around to see Professor Lupin, who looked both shaken and pleased.

"The dementors didn't affect me at all!" Harry said excitedly. "I didn't feel a thing!"

"That would be because they -- er -- weren't dementors," said Professor Lupin. "Come and see -- "

He led Harry out of the crowd until they were able to see the edge of the field.

"You gave Mr. Malfoy quite a fright," said Lupin.

Chapter: 13

"Nothing," shrugged Neville. "Want a game of Exploding Snap?"

"Er -- not now -- I was going to go to the library and do that vampire essay for Lupin --"

Chapter: 14

He strode across to his fire, seized a fistful of glittering powder from a jar on the fireplace, and threw it into the flames.

"Lupin!" Snape called into the fire. "I want a word!"

Utterly bewildered, Harry stared at the fire. A large shape had appeared in it, revolving very fast. Seconds later, Professor Lupin was clambering out of the fireplace, brushing ash off his shabby robes.

"You called, Severus?" said Lupin mildly.

"I certainly did," said Snape, his face contorted with fury as he strode back to his desk. "I have just asked Potter to empty his pockets. He was carrying this."

Snape pointed at the parchment, on which the words of Messrs. Moony, Wormtail, Padfoot, and Prongs were still shining. An odd, closed expression appeared on Lupin's face.

"Well?" said Snape.

Lupin continued to stare at the map. Harry had the impression that Lupin was doing some very quick thinking.

"Well?" said Snape again. "This parchment is plainly full of Dark Magic. This is supposed to be your area of expertise, Lupin. Where do you imagine Potter got such a thing?"

Lupin looked up and, by the merest half-glance in Harry's direction, warned him not to interrupt.

"Full of Dark Magic?" he repeated mildly. "Do you really think so, Severus? It looks to me as though it is merely a piece of parchment that insults anybody who reads it. Childish, but surely not dangerous? I imagine Harry got it from a joke shop --"

"Indeed?" said Snape. His jaw had gone rigid with anger. "You think a joke shop could supply him with such a thing? You don't think it more likely that he got it directly from the manufacturers?"

Harry didn't understand what Snape was talking about. Nor, apparently, did Lupin.

"You mean, by Mr. Wormtail or one of these people?" he said. "Harry, do you know any of these men?"

"No," said Harry quickly.

"You see, Severus?" said Lupin, turning back to Snape. "It looks like a Zonko product to me --"

Right on cue, Ron came bursting into the office. He was completely out of breath, and stopped just short of Snape's desk, clutching the stitch in his chest and trying to speak.

"I -- gave -- Harry -- that -- stuff," he choked. "Bought -- it... in Zonko's... ages -- ago..."

"Well!" said Lupin, clapping his hands together and looking around cheerfully. "That seems to clear that up! Severus, I'll take this back, shall I?" He folded the map and tucked it inside his robes. "Harry, Ron, come with me, I need a word about my vampire essay -- excuse us, Severus --"

Harry didn't dare look at Snape as they left his office. He. Ron, and Lupin walked all the way back into the entrance hall before speaking. Then Harry turned to Lupin.

"Professor, I --"

"I don't want to hear explanations," said Lupin shortly. He glanced around the empty entrance hall and lowered his voice. "I happen to know that this map was confiscated by Mr. Filch many years ago. Yes, I know it' s a map," he said as Harry and Ron looked amazed. "I don't want to know how it fell into your possession. I am, however, astounded that you didn't hand it in. Particularly after what happened the last time a student left information about the castle lying around. And I can't let you have it back, Harry."

Harry had expected that, and was too keen for explanations to protest.

"Why did Snape think I'd got it from the manufacturers?"

"Because...," Lupin hesitated, "because these mapmakers would have wanted to lure you out of school. They'd think it extremely entertaining."

"Do you know them?" said Harry, impressed.

"We've met," he said shortly. He was looking at Harry more seriously than ever before.

"Don't expect me to cover up for you again, Harry. I cannot make you take Sirius Black seriously. But I would have thought that what you have heard when the dementors draw near you would have had more of an effect on you. Your parents gave their lives to keep you alive, Harry. A poor way to repay them -- gambling their sacrifice for a bag of magic tricks."

He walked away, leaving Harry feeling worse by far than he had at any point in Snape's office. Slowly, he and Ron mounted the marble staircase. As Harry passed the one-eyed witch, he remembered the Invisibility Cloak -- it was still down there, but he didn't dare go and get it.

"It's my fault," said Ron abruptly. "I persuaded you to go. Lupin's right, it was stupid, we shouldn't've done it --"

Chapter: 14

But nobody had as much to do as Hermione. Even without Divination, she was taking more subjects than anybody else. She was usually last to leave the common room at night, first to arrive at the library the next morning; she had shadows like Lupin's under her eyes, and seemed constantly close to tears.

Chapter: 15

Their second to last exam, on Thursday morning, was Defense Against the Dark Arts. Professor Lupin had compiled the most unusual exam any of them had ever taken; a sort of obstacle course outside in the sun, where they had to wade across a deep paddling pool containing a grindylow, cross a series of potholes full of Red Caps, squish their way across a patch of marsh while ignoring misleading directions from a hinkypunk, then climb into an old trunk and battle with a new boggart.

"Excellent, Harry," Lupin muttered as Harry climbed out of the trunk, grinning. "Full marks."

Flushed with his success, Harry hung around to watch Ron and Hermione. Ron did very well until he reached the hinkypunk, which successfully confused him into sinking waist-high into the quagmire. Hermione did everything perfectly until she reached the trunk with the boggart in it. After about a minute inside it, she burst out again, screaming.

"Hermione!" said Lupin, startled. "What's the matter?"

"P -- P -- Professor McGonagall!" Hermione gasped, pointing into the trunk. "Sh -- she said I'd failed everything!"

Chapter: 16

The door of the room burst open in a shower of red sparks and Harry wheeled around as Professor Lupin came hurtling into the room, his face bloodless, his wand raised and ready. His eyes flickered over Ron, lying on the floor, over Hermione, cowering next to the door, to Harry, standing there with his wand covering Black, and then to Black himself, crumpled and bleeding at Harry's feet.

"Expelliarmus!" Lupin shouted.

Harry's wand flew once more out of his hand; so did the two Hermione was holding. Lupin caught them all deftly, then moved into the room, staring at Black, who still had Crookshanks lying Protectively across his chest.

Harry stood there, feeling suddenly empty. He hadn't done it. His nerve had failed him. Black was going to be handed back to the dementors.

Then Lupin spoke, in a very tense voice.

"Where is he, Sirius?"

Harry looked quickly at Lupin. He didn't understannd what Lupin meant. Who was Lupin talking about? He turned to look at Black again.

Black's face was quite expressionless. For a few seconds, he didn't move at all. Then, very slowly, he raised his empty hand and pointed straight at Ron. Mystified, Harry glanced around at Ron, who looked bewildered.

"But then..." Lupin muttered, staring at Black so intently it seemed he was trying to read his mind, "... why hasn't he shown himself before now? Unless" -- Lupin's eyes suddenly widened, as though he was seeing something beyond Black, something none of the rest could see, "-- unless he was the one... unless you switched... without telling me?"

Very slowly, his sunken gaze never leaving Lupin's face, Black nodded.

"Professor," Harry interrupted loudly, "what's going on --?"

But he never finished the question, because what he saw made his voice die in his throat. Lupin was lowering his wand, gazing fixed at Black. The Professor walked to Black's side, seized his hand, pulled him to his feet so that Crookshanks fell to the floor, and embraced Black like a brother.

Harry felt as though the bottom had dropped out of his stomach.

"DON'T BELIEVE IT!" Hermione screamed.

Lupin let go of Black and turned to her. She had raised herself off the floor and was pointing at Lupin, wild-eyed. "You -- you --"

"Hermione --"

"-- you and him!"

"Hermione, calm down --"

"I didn't tell anyone!" Hermione shrieked. "I've been covering up for you --"

"Hermione, listen to me, please'" Lupin shouted. "I can explain --"

Harry could feel himself shaking, not with fear, but with a fresh wave of fury.

"I trusted you," he shouted at Lupin, his voice wavering, out of control, "and all the time you've been his friend!"

"You're wrong," said Lupin. "I haven't been Sirius's friend, but I am now -- Let me explain...."

"NO!" Hermione screamed. "Harry, don't trust him, he's been helping Black get into the castle, he wants you dead too -- he's a werewolf!"

There was a ringing silence. Everyone's eyes were now on Lupin, who looked remarkably calm, though rather pale.

"Not at all up to your usual standard, Hermione," he said. "Only one out of three, I'm afraid. I have not been helping Sirius get into the castle and I certainly don't want Harry dead. An odd shiver passed over his face. "But I won't deny that I am a werewolf."

Ron made a valiant effort to get up again but fell back with a whimper of pain. Lupin made toward him, looking concerned, but Ron gasped, "Get away ftom me, werewolf!"

Lupin stopped dead. Then, with an obvious effort, he turned to Hermione and said, "How long have you known?"

"Ages," Hermione whispered. "Since I did Professor Snape's essay..."

"He'll be delighted," said Lupin coolly. "He assigned that essay hoping someone would realize what my symptoms meant.... Did you check the lunar chart and realize that I was always ill at the full moon? Or did you realize that the boggart changed into the moon when it saw me?"

"Both," Hermione said quietly.

Lupin forced a laugh.

"You're the cleverest witch of your age I've ever met, Hermione."

"I'm not," Hermione whispered. "If I'd been a bit cleverer, I'd have told everyone what you are!"

"But they already know," said Lupin. "At least, the staff do."

"Dumbledore hired you when he knew you were a werewolf. Ron gasped. "Is he mad?"

"Some of the staff thought so," said Lupin. "He had to work very hard to convince certain teachers that I'm trustworthy --"

"AND HE WAS WRONG!" Harry yelled. "YOUVE BEEN HELPING HIM ALL THE TIME!" He was pointing at Black, who suddenly crossed to the four-poster bed and sank onto it, his face hidden in one shaking hand. Crookshanks leapt up beside him and stepped onto his lap, purring. Ron edged away from both of them, dragging his leg.

I have not been helping Sirius," said Lupin. "If you'll give me a chance, I'll explain. Look --"

He separated Harry's, Ron's and Hermione's wands and threw each back to its owner; Harry caught his, stunned.

There, said Lupin, sticking his own wand back into his belt "You're armed, we're not. Now will you listen?"

Harry didn't know what to think. Was it a trick?

"If you haven't been helping him," he said, with a furious glance at Black, "how did you know he was here?"

"The map," said Lupin. "The Marauder's Map. I was in my office examining it --"

"You know how to work it?" Harry said suspiciously.

"Of course I know how to work it," said Lupin, waving his hand impatiently. "I helped write it. I'm Moony -- that was my friends' nickname for me at school."

"You wrote --?"

"The important thing is, I was watching it carefully this evening, because I had an idea that you, Ron, and Hermione might try and sneak out of the castle to visit Hagrid before his hippogriff was executed. And I was right, wasn't I"

He had started to pace up and down, looking at them. Little patches of dust rose at his feet.

"You might have been wearing your father's old cloak, Harry--"

"How d'you know about the cloak?"

"The number of times I saw James disappearing under it...," said Lupin, waving an impatient hand again. "The point is, even if you're wearing an Invisibility Cloak, you still show up on the Marauder's Map. I watched you cross the grounds and enter Hagrid's hut. Twenty minutes later, you left Hagrid, and set off back toward the castle. But you were now accompanied by somebody else."

"What?" said Harry. "No, we weren't!"

I couldn't believe my eyes," said Lupin, still pacing, and ignoring Harry's interruption. "I thought the map must be malfunctioning. How could he be with you?" "No one was with us!" said Harry.

"And then I saw another dot, moving fast toward you, labeled Sirius Black.... I saw him collide with you; I watched as he pulled two of you into the Whomping Willow --"

"One of us!" Ron said angrily.

"No, Ron," said Lupin. "Two of you."

He had stopped his pacing, his eyes moving over Ron.

"Do you think I could have a look at the rat?" he said evenly.

"What?" said Ron. "What's Scabbers got to do with it?"

"Everything," said Lupin. "Could I see him, please?"

Ron hesitated, then put a hand inside his robes. Scabbers emerged, thrashing desperately; Ron had to seize his long bald tail to stop him escaping. Crookshanks stood up on Black's leg and made a soft hissing noise.

Lupin moved closer to Ron. He seemed to be holding his breath as he gazed intently at Scabbers.

"What?" Ron said again, holding Scabbers close to him, looking scared. "What's my rat got to do with anything?"

"That's not a rat," croaked Sirius Black suddenly.

"What d'you mean -- of course he's a rat --"

"No, he's not," said Lupin quietly. "He's a wizard."

"An Animagus," said Black, "by the name of Peter Pettigrew."

Chapter: 17

It took a few seconds for the absurdity of this statement to sink in. Then Ron voiced what Harry was thinking.

"You're both mental."

"Ridiculous!" said Hermione faintly.

"Peter Pettigrew's dead!" said Harry. "He killed him twelve years ago!" He pointed at Black, whose face twitched convulsively.

"I meant to," he growled, his yellow teeth bared, "but little Peter got the better of me... not this time, though!"

And Crookshanks was thrown to the floor as Black lunged at Scabbers; Ron yelled with pain as Black's weight fell on his broken leg.

"Sirius, NO!" Lupin yelled, launching himself forwards and dragging Black away from Ron again, "WAIT! You can't do it just like that -- they need to understand -- we've got to explain --"

"We can explain afterwards!" snarled Black, trying to throw Lupin off. One hand was still clawing the air as it tried to reach Scabbers, who was squealing like a piglet, scratching Ron's face and neck as he tried to escape.

"They've -- got -- a -- right -- to -- know -- -everything!" Lupin panted, still trying to restrain Black. "Ron's kept him as a pet! There are parts of it even I don't understand, and Harry -- you owe Harry the truth, Sirius!"

Black stopped struggling, though his hollowed eyes were still fixed on Scabbers, who was clamped tightly under Ron's bitten, scratched, ad bleeding hands.

"All right, then," Black said, without taking his eyes off the rat.

"Tell them whatever you like. But make it quick, Remus. I want to commit the murder I was imprisoned for..."

"You're nutters, both of you," said Ron shakily, looking round at Harry and Hermione for support. "I've had enough of this. I'm off."

He tried to heave himself up on his good leg, but Lupin raised his wand again, pointing it at Scabbers.

"You're going to hear me out, Ron," he said quietly. "Just keep a tight hold on Peter while you listen."

"HE'S NOT PETER, HE'S SCABBERS!" Ron yelled, trying to fore the rat back into his front pocket, but Scabbers was fighting to hard; Ron swayed and overbalanced, and Harry caught him am pushed him back down to the bed. Then, ignoring Black, Harry turned to Lupin.

There were witnesses who saw Pettigrew die," he said. "A whole street full of them..."

"They didn't see what they thought they saw!" said Black savagely, still watching Scabbers struggling in Ron's hands.

"Everyone thought Sirius killed Peter," said Lupin, nodding. "I believed it myself -- until I saw the map tonight. Because the Marauder's map never lies... Peter's alive. Ron's holding him, Harry."

Harry looked down at Ron, and as their eyes met, they agreed, silently: Black and Lupin were both out of their minds. Their story made no sense whatsoever. How could Scabbers be Peter Pettigrew? Azkaban must have unhinged Black after all -- but why was Lupin playing along with him?

Then Hermione spoke, in a trembling, would-be calm sort of voice, as though trying to will Professor Lupin to talk sensibly.

"But Professor Lupin... Scabbers can't be Pettigrew... it just can't be true, you know it can't..."

"Why can't it be true?" Lupin said calmly, as though they were in class, and Hermione had simply spotted a problem in an experiment with grindylows.

"Because... because people would know if Peter Pettigrew had been an Animagus. We did Animagi in class with Professor McGonagall. And I looked them up when I did my homework -- the Ministry of Magic keeps tabs on witches and wizards who can become animals; there's a register showing what animal they become, and their markings and things... and I went and looked Professor McGonagall up on the register, and there have been only seven Animagi this century, and Pettigrew's name wasn't on the list."

Harry had barely had time to marvel inwardly at the effort Hermione put into her homework, when Lupin started to laugh.

"Right again, Hermione!" he said. "But the Ministry never knew that here used to be three unregistered Animagi running around Hogwarts."

"I you're going to tell them the story, get a move on, Remus," said Black, who was still watching Scabbers's every desperate move. "I've waited twelve years, I'm not going to wait much longer."

"All right... but you'll need to help me, Sirius," said Lupin, I only know how it began..."

Lupin broke off. There had been a loud creak behind him. The bedroom door had opened of its own accord. All five of them stared at it. Then Lupin strode toward it and looked out into the landing.

"No one there..."

"This place is haunted!" said Ron.

"It's not," said Lupin, still looking at the door in a puzzled way. "The Shrieking Shack was never haunted.... The screams and howls the villagers used to hear were made by me."

He pushed his graying hair out of his eyes, thought for a moment then said, "That's where all of this starts -- with my becoming a werewolf, None of this could have happened if I hadn't been bitter... and if I hadn't been so foolhardy..."

He looked sober and tired. Ron started to interrupt, but Hermione, said, "Shh!" She was watching Lupin very intently.

"I as a very small boy when I received the bite. My parents tried everything, but in those days there was no cure. The potion that Professor Snape has been making for me is a very recent discovery. It makes me safe, you see. As long as I take it in the week, preceding the full moon, I keep my mind when I transform.... I'm able to curl up in my office, a harmless wolf, and wait for the moon to wane again.

"Before the Wolfsbane Potion was discovered, however, I became a fully fledged monster once a month. It seemed impossible that I would be able to come to Hogwarts. Other parents weren't likely to want their children exposed to me.

"But then Dumbledore became Headmaster, and he was sympathetic. He said that as long as we took certain precautions, there was no reason I shouldn't come to school...." Lupin sighed, and looked directly at Harry. "I told you, months ago, that the Whomping Willow was planted the year I came to Hogwarts. The truth is that it was planted because I came to Hogwarts. This house" -- Lupin looked miserably around the room, -- "the tunnel that leads to it -- they were built for my use. Once a month, I was smuggled out of the castle, into this place, to transform. The tree was placed at the tunnel mouth to stop anyone coming across me while I was dangerous."

Harry couldn't see where this story was going, but he was listening raptly all the same. The only sound apart from Lupin's voice was Scabbers's frightened squeaking.

"My transformations in those days were -- were terrible. It is very painful to turn into a werewolf. I was separated from humans to bite, so I bit and scratched myself instead. The villagers heard the noise and the screaming and thought they were hearing particularly violent spirits. Dumbledore encouraged the rumor.... Even now, when the house has been silent for years, the villagers don't dare approach it...."

"But apart from my transformations, I was happier than I had ever been in my life. For the first time ever, I had friends, three great friends. Sirius Black... Peter Pettigrew... and, of course, your father, Harry -- James Potter."

"Now, my three friends could hardly fail to notice that I disappeared once a month. I made up all sorts of stories. I told them my mother was ill, and that I had to go home to see her... I was terrified they would desert me the moment they found out what I was. But of course, they, like you, Hermione, worked out the truth...."

"And they didn't desert me at all. Instead, they did something for me that would make my transformations not only bearable, but the best times of my life. They became Animagi."

"My dad too?" said Harry, astounded.

"Yes, indeed," said Lupin. "It took them the best part of three years to work out how to do it. Your father and Sirius here were the cleverest students in the school, and lucky they were, because the Animagus transformation can go horribly wrong -- one reason the Ministry keeps a close watch on those attempting to do it. Peter needed all the help he could get from James and Sirius. Finally, in our fifth year, they managed it. They could each turn into a different animal at will."

"But how did that help you?" said Hermione, sounding puzzled.

"They couldn't keep me company as humans, so they kept me company as animals," said Lupin. "A werewolf is only a danger to people. They sneaked out of the castle every month under James's Invisibility Cloak. They transformed... Peter, as the smallest, could slip beneath the Willow's attacking branches and touch the knot that freezes it. They would then slip down the tunnel and join me. Under their influence, I became less dangerous. My body was still wolfish, but my mind seemed to become less so while I was with them."

"Hurry up, Remus," snarled Black, who was still watching Scabbers with a horrible sort of hunger on his face.

"I'm getting there, Sirius, I'm getting there... well, highly exciting possibilities were open to us now that we could all transform. Soon we were leaving the Shrieking Shack and roaming the school grounds and the village by night. Sirius and James transformed into such large animals, they were able to keep a werewolf in check. I doubt whether any Hogwarts students ever found out more about the Hogwarts grounds and Hogsmeade than we did.... And that's how we came to write the Marauder's Map, and sign it with our nicknames. Sirius is Padfoot. Peter is Wormtail. James was Prongs."

"What sort of animal --?" Harry began, but Hermione cut him off.

"That was still really dangerous! Running around in the dark with a werewolf! What if you'd given the others the slip, and bitten somebody?"

"A thought that still haunts me," said Lupin heavily. "And there were near misses, many of them. We laughed about them afterwards. We were young, thoughtless -- carried away with our own cleverness."

I sometimes felt guilty about betraying Dumbledore's trust, of course... he had admitted me to Hogwarts when no other headmaster would have done so, and he had no idea I was breaking the rules he had set down for my own and others' safety. He never knew I had led three fellow students into becoming Animagi illegally. But I always managed to forget my guilty feelings every time we sat down to plan our next month's adventure. And I haven't changed..."

Lupin's face had hardened, and there was self-disgust in his voice. "All this year, I have been battling with myself, wondering whether I should tell Dumbledore that Sirius was an Animagus. But I didn't do it. Why? Because I was too cowardly. It would have meant admitting that I'd betrayed his trust while I was at school, admitting that I'd led others along with me... and Dumbledore's trust has meant everything to me. He let me into Hogwarts as a boy, and he gave me a job when I have been shunned all my adult life, unable to find paid work because of what I am. And so I convinced myself that Sirius was getting into the school using dark arts he learned from Voldemort, that being an Animagus had nothing to do with it... so, in a way, Snape's been right about me all along."

"Snape?" said Black harshly, taking his eyes off Scabbers; for the first time in minutes and looking up at Lupin. "What's Snape got to do with it?"

"He's here, Sirius," said Lupin heavily. "He's teaching here as well." He looked up at Harry, Ron, and Hermione.

"Professor Snape was at school with us. He fought very hard against my appointment to the Defense Against the Dark Arts job. He has been telling Dumbledore A year that I am not to be trusted. He has his reasons... you see, Sirius here played a trick on him which nearly killed him, a trick which involved me --"

Black made a derisive noise.

"It served him right," he sneered. "Sneaking around, trying to find out what we were up to... hoping he could get us expelled...."

"Severus was very interested in where I went every month." Lupin told Harry, Ron, and Hermione. "We were in the same year, you know, and we -- er -- didn't like each other very much. He especially disliked James. Jealous, I think, of James's talent on the Quidditch field... anyway Snape had seen me crossing the grounds with Madam Pomfrey one evening as she led me toward the Whomping Willow to transform. Sirius thought it would be -- er -- amusing, to tell Snape all he had to do was prod the knot on the tree trunk with a long stick, and he'd be able to get in after me. Well, of course, Snape tried it -- if he'd got as far as this house, he'd have met a fully grown werewolf -- but your father, who'd heard what Sirius had done, went after Snape and pulled him back, at great risk to his life... Snape glimpsed me, though, at the end of the tunnel. He was forbidden by Dumbledore to tell anybody, but from that time on he knew what I was...."

"So that's why Snape doesn't like you," said Harry slowly, "because he thought you were in on the joke?"

"That's right," sneered a cold voice from the wall behind Lupin.

Severus Snape was pulling off the Invisibility Cloak, his wand pointing, directly at Lupin.

Chapter: 18

Hermione screamed. Black leapt to his feet. Harry felt as though he'd received a huge electric shock.

"I found this at the base of the Whomping Willow," said Snape, throwing the cloak aside, careful to keep this wand pointing directly at Lupin's chest. "Very useful, Potter, I thank you...."

Snape was slightly breathless, but his face was full of suppressed triumph. "You're wondering, perhaps, how I knew you were here?" he said, his eyes glittering. "I've just been to your office, Lupin. You forgot to take your potion tonight, so I took a gobletful along. And very lucky I did... lucky for me, I mean. Lying on your desk was a certain map. One glance at it told me all I needed to know. I saw you running along this passageway and out of sight."

"Severus --" Lupin began, but Snape overrode him.

"I've told the headmaster again and again that you're helping your old friend Black into the castle, Lupin, and here's the proof. Not even I dreamed you would have the nerve to use this old place as your hideout --"

"Severus, you're making a mistake," said Lupin urgently. "You haven't heard everything -- I can explain -- Sirius is not here to kill Harry --"

"Two more for Azkaban tonight," said Snape, his eyes now gleaming fanatically. "I shall be interested to see how Dumbledore takes this.... He was quite convinced you were harmless, you know, Lupin... a tame werewolf --"

"You fool," said Lupin softly. "Is a schoolboy grudge worth putting an innocent man back inside Azkaban?"

BANG! Thin, snakelike cords burst from the end of Snape's wand and twisted themselves around Lupin's mouth, wrists, and ankles; he overbalanced and fell to the floor, unable to move. With a roar of rage, Black started toward Snape, but Snape pointed his wand straight between Black's eyes.

"Give me a reason," he whispered. "Give me a reason to do it, and I swear I will."

Black stopped dead. It would have been impossible to say which face showed more hatred.

Harry stood there, paralyzed, not knowing what to do or whom to believe. He glanced around at Ron and Hermione. Ron looked just as confused as he did, still fighting to keep hold on the struggling Scabbers. Hermione, however, took an uncertain step toward Snape and said, in a very breathless voice, "Professor Snape -- it it wouldn't hurt to hear what they've got to say, w -- would it?"

"Miss Granger, you are already facing suspension from this school," Snape spat. "You, Potter, and Weasley are out-of-bounds, in the company of a convicted murderer and a werewolf. For once in your life, hold your tongue."

"But if -- if there was a mistake --"

"KEEP QUIET, YOU STUPID GIRL!" Snape shouted, looking suddenly quite deranged. "DON'T TALK ABOUT WHAT YOU DON'T UNDERSTAND!" A few sparks shot out of the end of his wand, which was still pointed at Black's face. Hermione fell silent.

"Vengeance is very sweet," Snape breathed at Black. "How I hoped I would be the one to catch you...."

"The joke's on you again, Severus," Black snarled. "As long as this boy brings his rat up to the castle" -- he jerked his head at Ron -- "I'll come quietly...."

"Up to the castle?" said Snape silkily. "I don't think we need to go that far. All I have to do is call the dementors once we get out of the Willow. They'll be very pleased to see you, Black... pleased enough to give you a little kiss, I daresay... I --"

What little color there was in Blacks face left it.

"You -you've got to hear me out," he croaked. "The rat -- look at the rat --"

But there was a mad glint in Snape's eyes that Harry had never seen before. He seemed beyond reason.

"Come on, all of you," he said. He clicked his fingers, and the ends of the cords that bound Lupin flew to his hands. "I'll drag the werewolf. Perhaps the dementors will have a kiss for him too --"

Before he knew what he was doing, Harry had crossed the room in three strides and blocked the door.

"Get out of the way, Potter, you're in enough trouble already," snarled Snape. "If I hadn't been here to save your skin --"

"Professor Lupin could have killed me about a hundred times this year," Harry said. "I've been alone with him loads of times, having defense lessons against the dementors. If he was helping Black, why didn't he just finish me off then?"

"Don't ask me to fathom the way a werewolf's mind works," hissed Snape. "Get out of the way, Potter."

"YOURE PATHETIC!" Harry yelled. "JUST BECAUSE THEY MADE A FOOL OF YOU AT SCHOOL YOU WON'T EVEN LISTEN --"

"SILENCE! I WILL NOT BE SPOKEN TO LIKE THAT!" Snape shrieked, looking madder than ever. "Like father, like son, Potter! I have just saved your neck; you should be thanking me on bended knee! You would have been well served if he'd killed you! You'd have died like your father, too arrogant to believe you might be mistaken in Black -- now get out of the way, or I will make you. GET OUT OF THE WAY, POTTER!"

Harry made up his mind in a split second. Before Snape could take even one step toward him, he had raised his wand.

"Expelliarmus!" he yelled -- except that his wasn't the only voice that shouted. There was a blast that made the door rattle on its hinges; Snape was lifted off his feet and slammed into the wall, then slid down it to the floor, a trickle of blood oozing from under his hair. He had been knocked out.

Harry looked around. Both Ron and Hermione had tried to disarm Snape at exactly the same moment. Snape's wand soared in a high arc and landed on the bed next to Crookshanks.

"You shouldn't have done that," said Black, looking at Harry.

"You should have left him to me...."

Harry avoided Black's eyes. He wasn't sure, even now, that he'd done the right thing.

"We attacked a teacher... We attacked a teacher..." Hermione whimpered, staring at the lifeless Snape with frightened eyes. "Oh, we're going to be in so much trouble --"

Lupin was struggling against his bonds. Black bent down quickly and untied him. Lupin straightened up, rubbing his arms where the ropes had cut into them.

"Thank you, Harry," he said.

"I'm still not saying I believe you," he told Lupin.

"Then it's time we offered you some proof," said Lupin. "You, boy -- give me Peter, please. Now."

Ron clutched Scabbers closer to his chest.

"Come off it," he said weakly. "Are you trying to say he broke out of Azkaban just to get his hands on Scabbers? I mean..." He looked up at Harry and Hermione for support, "Okay, say Pettigrew could turn into a rat -- there are millions of rats -- how's he supposed to know which one he's after if he was locked up in Azkaban?"

"You know, Sirius, that's a fair question," said Lupin, turning to Black and frowning slightly. "How did you find out where he was?"

Black put one of his clawlike hands inside his robes and took out a crumpled piece of paper, which he smoothed flat and held out to show the others.

It was the photograph of Ron and his family that had appeared in the Daily Prophet the previous summer, and there, on Ron's shoulder, was Scabbers.

"How did you get this?" Lupin asked Black, thunderstruck.

"Fudge," said Black. "When he came to inspect Azkaban last year, he gave me his paper. And there was Peter, on the front page on this boy's shoulder... I knew him at once... how many times had I seen him transform? And the caption said the boy would be going back to Hogwarts... to where Harry was...

"My God," said Lupin softly, staring from Scabbers to the picture in the paper and back again. "His front paw..."

"What about it?" said Ron defiantly.

"He's got a toe missing," said Black.

"Of course," Lupin breathed. "So simple... so brilliant... he cut it off himself?"

"Just before he transformed," said Black. "When I cornered him, he yelled for the whole street to hear that I'd betrayed Lily and James. Then, before I could curse him, he blew apart the street with the wand behind his back, killed everyone within twenty feet of himself -- and sped down into the sewer with thee other rats...."

"Didn't you ever hear, Ron?" said Lupin. "The biggest bit of Peter they found was his finger."

"Look, Scabbers probably had a fight with another rat or something! He's been in my family for ages, right --"

"Twelve years, in fact," said Lupin. "Didn't you ever wonder why he was living so long?"

"We -- we've been taking good care of him!" said Ron.

"Not looking too good at the moment, though, is he?" said Lupin. "I'd guess he's been losing weight ever since he heard Sirius was on the loose again...."

"He's been scared of that mad cat!" said Ron, nodding toward Crookshanks, who was still purring on the bed.

But that wasn't right, Harry thought suddenly... Scabbers had been looking ill before he met Crookshanks... ever since Ron's return from Egypt... since the time when Black had escaped....

"This cat isn't mad," said Black hoarsely. He reached out a bony hand and stroked Crookshanks's fluffy head. "He's the most intelligent of his kind I've ever met. He recognized Peter for what he was right away. And when he met me, he knew I was no dog. It was a while before he trusted me.... Finally, I managed to communicate to him what I was after, and he's been helping me. .. "What do you mean?" breathed Hermione.

"He tried to bring Peter to me, but couldn't... so he stole the passwords into Gryffindor Tower for me.... As I understand it, he took them from a boy's bedside table...."

Harry's brain seemed to be sagging under the weight of what he was hearing. It was absurd... and yet...

"But Peter got wind of what was going on and ran for it." croaked Black. "This cat -- Crookshanks, did you call him? -- told me Peter had left blood on the ssheets.... I supposed he bit himself... Well, faking his own death had worked once."

These words jolted Harry to his senses.

"And why did he fake his death?" he said furiously. "Because he knew you were about to kill him like you killed my parents!"

"No," said Lupin, "Harry-"

"And now you've come to finish him off!"

"Yes, I have," said Black, with an evil look at Scabbers.

"Then I should've let Snape take you!" Harry shouted.

"Harry," said Lupin hurriedly, "don't you see? All this time we've thought Sirius betrayed your parents, and Peter tracked him down -- but it was the other way around, don't you see? Peter betrayed your mother and father -- Sirius tracked Peter down --"

"THAT'S NOT TRUE!" Harry yelled. "HE WAS THEIR SECRET-KEEPER! HE SAID SO BEFORE YOU TURNED UP. HE SAID HE KILLED THEM!"

He was pointing at Black, who shook his head slowly; the sunken eyes were suddenly over bright.

"Harry... I as good as killed them," he croaked. "I persuaded Lily and James to change to Peter at the last moment, persuaded them to use him as Secret-Keeper instead of me.... I'm to blame, I know it.... The night they died, I'd arranged to check on Peter, make sure he was still safe, but when I arrived at his hiding place, he'd gone. Yet there was no sign of a struggle. It didn't feel right. I was scared. I set out for your parents' house straight away. And when I saw their house, destroyed, and their bodies... I realized what Peter must've done... what I'd done...."

His voice broke. He turned away.

"Enough of this," said Lupin, and there was a steely note in his voice Harry had never heard before. "There's one certain way to prove what really happened. Ron, give me that rat."

"What are you going to do with him if I give him to you?" Ron asked Lupin tensely.

"Force him to show himself," said Lupin. "If he really is a rat, it won't hurt him."

Ron hesitated. Then at long last, he held out Scabbers and Lupin took him. Scabbers began to squeak without stopping, twisting and turning, his tiny black eyes bulging in his head. "Ready, Sirius?" said Lupin.

Black had already retrieved Snape's wand from the bed. He approached Lupin and the struggling rat, and his wet eyes suddenly seemed to be burning in his face.

"Together?" he said quietly.

"I think so,,, said Lupin, holding Scabbers tightly in one hand and his wand in the other. "On the count of three. One -- two -- THREE!"

A flash of blue-white light erupted from both wands; for a moment, Scabbers was frozen in midair, his small gray form twisting madly -- Ron yelled -- the rat fell and hit thhe floor. There was another blinding flash of light and then --

It was like watching a speeded-up film of a growing tree. A head was shooting upward from the ground; limbs were sprouting; a moment later, a man was standing where Scabbers had been, cringing and wringing his hands. Crookshanks was spitting and snarling on the bed; the hair on his back was standing up.

He was a very short man, hardly taller than Harry and Hermione. His thin, colorless hair was unkempt and there was a large bald patch on top. He had the shrunken appearance of a plump man who has lost a lot of weight in a short time. His skin looked grubby, almost like Scabbers's fur, and something of the rat lingered around his pointed nose and his very small, watery eyes. He looked around at them all, his breathing fast and shallow. Harry saw his eyes dart to the door and back again.

"Well, hello, Peter," said Lupin pleasantly, as though rats frequently erupted into old school friends around him. "Long time, no see.

"S -- Sirius... R -- Remus..." Even Pettigrew's voice was squeaky. Again, his eyes darted toward the door. "My friends... my old friends..."

Black's wand arm rose, but Lupin seized him around the wrist, gave him a warning took, then turned again to Pettigrew, his voice light and casual.

"We've been having a little chat, Peter, about what happened the night Lily and James died. You might have missed the finer points while you were squeaking around down there on the bed --"

"Remus," gasped Pettigrew, and Harry could see beads of sweat breaking out over his pasty face, "you don't believe him, do you...? He tried to kill me, Remus...."

"So we've heard," said Lupin, more coldly. "I'd like to clear up one or two little matters with you, Peter, if you'll be so --"

"He's come to try and kill me again!" Pettigrew squeaked suddenly, pointing at Black, and Harry saw that he used his middle finger, because his index was missing. "He killed Lily and James and now he's going to kill me too.... You've got to help me, Remus...."

Black's face looked more skull-like than ever as he stared at Pettigrew with his fathomless eyes.

"No one's going to try and kill you until we've sorted a few things out," said Lupin.

"Sorted things out?" squealed Pettigrew, looking wildly about him once more, eyes taking in the boarded windows and, again' the only door. "I knew he'd come after me! I knew he'd be back for me! I've been waiting for this for twelve years!"

"You knew Sirius was going to break out of Azkaban?" said Lupin, his brow furrowed. "When nobody has ever done it before?"

"He's got dark powers the rest of us can only dream of!" Pettigrew shouted shrilly. "How else did he get out of there? I suppose He-Who-Must-Not-Be-Named taught him a few tricks!"

Black started to laugh, a horrible, mirthless laugh that filled the whole room.

"Voldemort, teach me tricks?" he said.

Pettigrew flinched as though Black had brandished a whip at him.

"What, scared to hear your old master's name?" said Black. I don't blame you, Peter. His lot aren't very happy with you, are they?"

"Don't know what you mean, Sirius --" muttered Pettigrew, his breathing faster than ever. His whole face was shining with sweat now.

"You haven't been hiding from me for twelve years," said Black. "You've been hiding from Voldemort's old supporters. I heard things in Azkaban, Peter... They all think you're dead, or you'd have to answer to them.... I've heard them screaming all sorts of things in their sleep. Sounds like they think the double-crosser double-crossed them. Voldemort went to the Potters' on your information... and Voldemort met his downfall there. And not all Voldemort's supporters ended up in Azkaban, did they? There are still plenty out here, biding their time, pretending they've seen the error of their ways.

If they ever got wind that you were still alive, Peter --"

"Don't know... what you're talking about...," said Pettigrew again, more shrilly than ever. He wiped his face on his sleeve and looked up at Lupin. "You don't believe this -- this madness, Remus --"

"I must admit, Peter, I have difficulty in understanding why an innocent man would want to spend twelve years as a rat," said Lupin evenly.

"Innocent, but scared!" squealed Pettigrew. "If Voldemort's supporters were after me, it was because I put one of their best men in Azkaban -- the spy, Sirius Black!"

Black's face contorted.

"How dare you," he growled, sounding suddenly like the bearsized dog he had been. I, a spy for Voldemort? When did I ever sneak around people who were stronger and more powerful than myself? But you, Peter -- I'll never understand why I didn't see you were the spy from the start. You always liked big friends who'd look after you, didn't you? It used to be us... me and Remus... and James....

Pettigrew wiped his face again; he was almost panting for breath.

"Me, a spy... must be out of your mind... never... don't know how you can say such a --"

"Lily and James only made you Secret-Keeper because I suggested it," Black hissed, so venomously that Pettigrew took a step backward. "I thought it was the perfect plan... a bluff... Voldemort would be sure to come after me, would never dream they'd use a weak, talentless thing like you.... It must have been the finest moment of your miserable life, telling Voldemort you could hand him the Potters."

Pettigrew was muttering distractedly; Harry caught words like "far-fetched" and "lunacy," but he couldn't help paying more attention to the ashen color of Pettigrew's face and the way his eyes continued to dart toward the windows and door.

"Professor Lupin?" said Hermione timidly. "Can -- can I say something?"

"Certainly, Hermione," said Lupin courteously.

"Well -- Scabbers -- I mean, this -- this man -- he's been sleeping in Harry's dormitory for three years. If he's working for You-Know-Who, how come he never tried to hurt Harry before now?"

"There!" said Pettigrew shrilly, pointing at Ron with his maimed hand. "Thank you! You see, Remus? I have never hurt a hair of Harry's head! Why should I?"

Chapter: 19

"Thank you!" gasped Pettigrew, nodding frantically at her. "Exactly! Precisely what I --"

But Lupin silenced him with a look. Black was frowning slightly at Hermione, but not as though he were annoyed with her. He seemed to be pondering his answer.

Chapter: 19

"Remus!" Pettigrew squeaked, turning to Lupin instead, writhing imploringly in front of him. "You don't believe this wouldn't Sirius have told you they'd changed the plan?"

"Not if he thought I was the spy, Peter," said Lupin. "I assume that's why you didn't tell me, Sirius?" he said casually over Pettigrews head.

"Forgive me, Remus," said Black.

"Not at all, Padfoot, old friend," said Lupin, who was now rolling up his sleeves. "And will you, in turn, forgive me for believing you were the spy?"

"Of course," said Black, and the ghost of a grin flitted across his gaunt face. He, too, began rolling up his sleeves. "Shall we kill him together?"

"Yes, I think so," said Lupin grimly.

Chapter: 19

Both Black and Lupin strode forward, seized Pettigrew's shoulders, and threw him backward onto the floor. He sat there, twitching with terror, staring up at them.

Chapter: 19

"THEN YOU SHOULD HAVE DIED!" roared Black. "DIED RATHER THAN BETRAY YOUR FRIENDS, AS WE WOULD HAVE DONE FOR YOU!"

Black and Lupin stood shoulder to shoulder, wands raised.

"You should have realized," said Lupin quietly, "if Voldemort didn't kill you, we would. Good-bye, Peter."

Hermione covered her face with her hands and turned to the wall.

"NO!" Harry yelled. He ran forward, placing himself in front Pettigrew, facing the wands. "You can't kill him," he said breathlessly. "You can't."

Black and Lupin both looked staggered.

Chapter: 19

No one moved or made a sound except Pettigrew, whose breath was coming in wheezes as he clutched his chest. Black and Lupin were looking at each other. Then, with one movement, they lowered their wands.

Chapter: 19

Pettigrew was still wheezing behind him.

"Very well," said Lupin. "Stand aside, Harry."

Harry hesitated.

"I'm going to tie him up," said Lupin. "That's all, I swear."

Harry stepped out of the way. Thin cords shot from Lupin's wand this time, and next moment, Pettigrew was wriggling on the floor, bound and gagged.

Chapter: 19

"Right," said Lupin, suddenly businesslike. "Ron, I can't mend bones nearly as well as Madam Pomfrey, so I think it's best if we just strap your leg up until we can get you to the hospital wing."

He hurried over to Ron, bent down, tapped Ron's leg with his wand, and muttered, "Ferula." Bandages spun up Ron's leg, strapping it tightly to a splint. Lupin helped him to his feet; Ron put his weight gingerly on the leg and didn't wince.

"That's better," he said. "Thanks."

"What about Professor Snape?" said Hermione in a small voice, looking down at Snape's prone figure.

"There's nothing seriously wrong with him," said Lupin, bending over Snape and checking his pulse. "You were just a little -- overenthusiastic. Still out cold. Er -- perhaps it will be best if we don't revive him until we're safety back in the castle. We can take him like this...."

He muttered, "Mobilicorpus." As though invisible strings were tied to Snape's wrists, neck, and knees, he was pulled into a standing position, head still lolling unpleasantly, like a grotesque puppet. He hung a few inches above the ground, his limp feet dangling. Lupin picked up the Invisibility Cloak and tucked it safely into his pocket.

"And two of us should be chained to this," said Black, nudging Pettigrew with his toe. "Just to make sure."

"I'll do it," said Lupin.

"And me," said Ron savagely, limping forward.

Black conjured heavy manacles from thin air; soon Pettigrew was upright again, left arm chained to Lupin's right, right arm to Ron's left. Ron's face was set. He seemed to have taken Scabbers's true identity as a personal insult. Crookshanks leapt lightly off the bed and led the way out of the room, his bottlebrush tail held jauntily high.

Chapter: 19

Harry had never been part of a stranger group. Crookshanks led the way down the stairs; Lupin, Pettigrew, and Ron went next, looking like entrants in a six-legged race. Next came Professor Snape, drifting creepily along, his toes hitting each stair as they descended, held up by his own wand, which was being pointed at him by Sirius. Harry and Hermione brought up the rear.

Getting back into the tunnel was difficult. Lupin, Pettigrew, and Ron had to turn sideways to manage it; Lupin still had Pettigrew covered with his wand. Harry could see them edging awkwardly along the tunnel in single file. Crookshanks was still in the lead. Harry went right after Black, who was still making Snape drift along ahead of them; he kept bumping his lolling head on the low ceiling. Harry had the impression Black was making no effort to prevent this.

Chapter: 20

They did not speak again until they had reached the end of the tunnel. Crookshanks darted up first; he had evidently pressed his paw to the knot on the trunk, because Lupin, Pettigrew, and Ron clambered upward without any sound of savaging branches.

Chapter: 20

"One wrong move, Peter," said Lupin threateningly ahead. His wand was still pointed sideways at Pettigrew's chest.

Chapter: 20

A cloud shifted. There were suddenly dim shadows on the ground. Their party was bathed in moonlight.

Snape collided with Lupin, Pettigrew, and Ron, who had stopped abruptly. Black froze. He flung out one arm to make Harry and Hermione stop.

Harry could see Lupin's silhouette. He had gone rigid. Then his limbs began to shake.

"Oh, my --" Hermione gasped. "He didn't take his potion tonight! He's not safe!"

"Run," Black whispered. "Run. Now."

But Harry couldn't run. Ron was chained to Pettigrew and Lupin. He leapt forward but Black caught him around the chest and threw him back.

"Leave it to me -- RUN!"

There was a terrible snarling noise. Lupin's head was lengthening. So was his body. His shoulders were hunching. Hair was sprouting visibly on his face and hands, which were curling into clawed paws. Crookshanks's hair was on end again; he was backing away --

As the werewolf reared, snapping its long jaws, Sirius disappeared from Harry's side. He had transformed. The enormous, bearlike dog bounded forward. As the werewolf wrenched itself free of the manacle binding it, the dog seized it about the neck and pulled it backward, away from Ron and Pettigrew. They were locked, jaw to jaw, claws ripping at each other.

Harry stood, transfixed by the sight, too intent upon the battle to notice anything else. It was Hermione's scream that alerted him --

Pettigrew had dived for Lupin's dropped wand.

Chapter: 20

Harry looked desperately around. Black and Lupin both gone... they had no one but Snape for company, still hanging, unconscious, in midair.

Chapter: 20

"Professor, Black's telling the truth -- we saw Pettigrew "-- he escaped when Professor Lupin turned into a werewolf --"

Chapter: 21

"Professor Lupin can tell you --" Harry said, unable to stop himself

"Professor Lupin is currently deep in the forest, unable to tell anyone anything. By the time he is human again, it will be too late, Sirius will be worse than dead. I might add that werewolves are so mistrusted by most of our kind that his support will count for very little -- and the fact that he and Sirius are oold friends --"

Chapter: 21

They watched the four men climb the castle steps and disappear from view. For a few minutes the scene was deserted. Then --

"Here comes Lupin!" said Harry as they saw another figure sprinting down the stone steps and hating toward the Willow. Harry looked up at the sky. Clouds were obscuring the moon completely.

They watched Lupin seize a broken branch from the ground and prod the knot on the trunk. The tree stopped fighting, and Lupin, too, disappeared into the gap in its roots.

"If he'd only grabbed the cloak," said Harry. "It's just lying there...."

Chapter: 21

She and Harry got to their feet. Buckbeak raised his head. They saw Lupin, Ron, and Pettigrew clambering awkwardly out of the hole in the roots. Then came Hermione... then the unconscious Snape, drifting weirdly upward. Next came Harry and Black. They all began to walk toward the castle.

Harry's heart was starting to beat very fast. He glanced up at the sky. Any moment now, that cloud was going to move aside and show the moon....

Chapter: 21

"There goes Lupin," Hermione whispered. "He's transforming

"Hermione!" said Harry suddenly. "We've got to move!"

"We mustn't, I keep telling you --"

"Not to interfere! Lupin's going to run into the forest, right at us!"

Hermione gasped.

Chapter: 21

"Yeah... can't've tied him up properly," said Hagrid, gazing happily out over the grounds. "I was worried this mornin', mind... thought he mighta met Professor Lupin on the grounds, but Lupin says he never ate anythin' las' night...."

"What?" said Harry quickly.

"Blimey, haven' yeh heard?" said Hagrid, his smile fading a little. He lowered his voice, even though there was nobody in sight. "Er -- Snape told all the Slytherins this mornin'.... Thought everyone'd know by now... Professor Lupin's a werewolf, see. An' he was loose on the grounds las' night.... He's packin' now, o' course.

"He's packing?" said Harry, alarmed. "Why?"

"Leavin', isn' he?" said Hagrid, looking surprised that Harry had to ask. "Resigned firs' thing this mornin'. Says he can't risk it happenin again.

Harry scrambled to his feet.

"I'm going to see him," he said to Ron and Hermione.

"But if he's resigned --"

"-- doesn't sound like there's anything we can do --"

"I don't care. I still want to see him. I'll meet you back here."

Lupin's office door was open. He had already packed most of his things. The grindylow's empty tank stood next to his battered old suitcase, which was open and nearly full. Lupin was bending over something on his desk and looked up only when Harry knocked on the door.

"I saw you coming," said Lupin, smiling. He pointed to the parchment he had been poring over. It was the Marauder's Map.

"I just saw Hagrid," said Harry. "And he said you'd resigned. It's not true, is it?"

"I'm afraid it is," said Lupin. He started opening his desk drawers and taking out the contents.

"Why?" said Harry. "The Ministry of Magic don't think you were helping Sirius, do they?"

Lupin crossed to the door and closed it behind Harry.

"No. Professor Dumbledore managed to convince Fudge that I was trying to save your lives." He sighed. "That was the final straw for Severus. I think the loss of the Order of Merlin hit him hard. So he -- er -- accidentally let slip that I am a werewolf this morning at breakfast."

"You're not leaving just because of that!" said Harry.

Lupin smiled wryly.

"This time tomorrow, the owls will start arriving from parents.... They will not want a werewolf teaching their children, Harry. And after last night, I see their point. I could have bitten any of you.... That must never happen again."

"You're the best Defense Against the Dark Arts- teacher we've ever had!" said Harry. "Don't go!"

Lupin shook his head and didn't speak. He carried on emptying his drawers. Then, while Harry was trying to think of a good argument to make him stay, Lupin said, "From what the headmaster told me this morning, you saved a lot of lives last night, Harry. if I'm proud of anything I've done this year, it's how much you've learned.... Tell me about your Patronus."

"How d'you know about that?" said Harry, distracted.

"What else could have driven the dementors back?"

Harry told Lupin what had happened. When he'd finished, Lupin was smiling again.

"Yes, your father was always a stag when he transformed," he said. "You guessed right... that's why we called him Prongs."

Lupin threw his last few books into his case, closed the desk drawers, and turned to look at Harry.

"Here -- I brought this from the Shrieking Shack last night," he said, handing Harry back the Invisibility Cloak. "And..." He hesitated, then held out the Marauder's Map too. "I am no longer your teacher, so I don't feel guilty about giving you back this as well. It's no use to me, and I daresay you, Ron, and Hermione will find uses for it."

Harry took the map and grinned.

"You told me Moony, Wormtail, Padfoot, and Prongs would've wanted to lure me out of school... you said they'd have thought it was funny."

"And so we would have," said Lupin, now reaching down to close his case. "I have no hesitation in saying that James would have been highly disappointed if his son had never found any of the secret passages out of the castle."

There was a knock on the door. Harry hastily stuffed the Marauder's Map and the Invisibility Cloak into his pocket.

It was Professor Dumbledore. He didn't look surprised to see Harry there.

"Your carriage is at the gates, Remus," he said.

"Thank You, Headmaster."

Lupin picked up his old suitcase and the empty grindylow tank.

"Well -- good-bye, Harry," he said, smiling. "It has been a real pleasure teaching you. I feel sure we'll meet again sometime. Headmaster, there is no need to see me to the gates, I can manage...."

Harry had the impression that Lupin wanted to leave as quickly as possible.

"Good-bye, then, Remus," said Dumbledore soberly. Lupin shifted the grindylow tank slightly so that he and Dumbledore could shake hands. Then, with a final nod to Harry and a swift smile, Lupin left the office.

Chapter: 22

"But -- I stopped Sirius and Professor Lupin from killing Pettigrew! That makes it my fault if Voldemort comes back!"

Chapter: 22

Though the weather was perfect, though the atmosphere was so cheerful, though he knew they had achieved the near impossible in helping Sirius to freedom, Harry had never approached the end of a school year in worse spirits.

He certainly wasn't the only one who was sorry to see Professor Lupin go. The whole of Harry's Defense Against the Dark Arts class was miserable about his resignation.

Chapter: 22

It wasn't only Professor Lupin's departure that was weighing on Harry's mind. He couldn't help thinking a lot about Professor Trelawney's prediction. He kept wondering where Pettigrew was now, whether he had sought sanctuary with Voldemort yet. But the thing that was lowering Harry's spirits most of all was the prospect of returning to the Dursleys. For maybe half an hour, a glorious half hour, he had believed he would be living with Sirius from now on... his parents' best friend.... It would have been the next best thing to having his own father back. And while no news of Sirius was definitely good news, because it meant he had successfully gone into hiding, Harry couldn't help feeling miserable when he thought of the home he might have had, and the fact that it was now impossible.

Chapter: 22
