St. Martin's Paperbacks. First published 1944.
A nicely told mystery about a young woman who apparently took her own life, rather bizarrely in the course of a dinner party. The story begins about a year later when there are premonitions of a similar repeat killing. Turns out, obviously, that the first death was murder, and the second is prevented. But how this happens, and how it is detected, is cleverly and charmingly related. The detective is not any of Christie's usuals - not Poirot or Marple, or even Tommy Tuppence. I doubt if the rather staid and colourless Chief Inspector Kemp appears in any other of her stories.
