Three men meet on a ship bound for Haiti, where corruption and terror reign under the dictatorship of Papa Doc and the Tontons Macoute, his sinister secret police. Disillusioned and noncommittal, they are the "comedians" of Greene's title. Brown is a disenchanted English hotel owner; the Smiths are an American couple on a good-will mission; Martha is the young wife of a Latin American diplomat; Jones is an engaging fool. They play their parts, respectable or shady, in the foreground, experiencing love affairs rather than love, enthusiasms but not a faith, and meaningless accidental deaths. Hiding behind their actors' masks, they hesitate on the edge of life, afraid of love, pain, and fear itself. With alternating comedy, irony, and grim violence, Greene weaves these lives in a pattern of mounting suspense.
