The Body in the Library (1942)
Blurb:
My review:
One of Christie's most accomplished parodies of a convention of the genre: the body in the library. The corpse, however, is that of a very tarty young woman, Ruby Keene (née Rosie Legge), and the library is that of the highly respectable stick-in-the-mud Colonel Bantry. Although the telling is staid and sober, there is plenty of detective interest to be found as the police investigate movements and motives of the guests at the Majestic Hotel; the unravelling of an ingenous yarn is done by Miss Marple, relying on her feminine knowledge of nails and teeth. The reader will almost certainly spot the identity of one of the murderers, but not of the other.
