Fiction

Three single girls share a London flat. The first works as a secretary; the second is an artist; the third, who comes to Poirot for help, disappears believing she is a murderer. There are rumors of revolvers, flick-knives, and blood stains. But, without hard evidence, it will take all of Poirot's tenacity to establish whether the third girl is guilty, innocent, or insane.
