A brilliant detective novel by Agatha Christie featuring the legendary detective Hercule Poirot. The story begins when the eccentric Mr. Shaitana hosts a dinner party and invites four detectives and four guests whom he suspects have committed murder in the past. During a game of bridge, Shaitana is murdered, leaving Poirot and his fellow investigators to determine which of the players is the killer.

Unlike many traditional mysteries, the novel focuses less on physical clues and more on psychology, character, and motive. Poirot must use his understanding of human nature to identify the murderer from a small group of suspects.
