When a series of apparently unconnected murders attracts the attention of Hercule Poirot, one small detail stands out: the mysterious recurrence of the number four. Poirot travels from London to Paris and from Belgium to Italy, solving one mystery after another but always remaining a step behind the shadowy foursome he suspects are responsible. A final daring confrontation puts the eccentric detective’s life on the line—until his twin brother, Achille Poirot, comes to the rescue.
