The Heart of the Matter, novel by Graham Greene, published in 1948. The work is considered by some critics to be part of a “Catholic trilogy” that included Greene’s Brighton Rock (1938) and The Power and the Glory (1940).
The novel is set during World War II in a bleak area of West Africa and concerns the moral dilemmas facing Scobie, an honourable and decent deputy commissioner of police who is torn between compassion for his wife, Louise, and love and pity for Helen, a young widow with whom he has an affair. Scobie gradually loses control of his life. Racked with guilt and self-loathing over his role in the accidental death of his loyal servant, Scobie plans to commit suicide. Fearing that knowledge of this mortal sin will cause pain to his wife and others, he attempts to disguise his suicide as death by natural causes.
