The Big Four (Hercule Poirot Mystery)

Beloved detective Hercule Poirot takes on an international gang of super-criminals and introduces the world to his identical twin, Achille Poirot. From Agatha Christie, who "created the modern murder mystery" (The New Yorker). 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. A VINTAGE CLASSIC MYSTERY
