The Razor's Edge is a 1944 novel by W. Somerset Maugham. It tells the story of Larry Darrell, an American pilot traumatized by his experiences in World War I, who sets off in search of some transcendent meaning in his life. The story begins through the eyes of Larry's friends and acquaintances as they witness his personality change after the war. His rejection of conventional life and search for meaningful experience allows him to thrive while the more materialistic characters suffer reversals of fortune.

William Somerset Maugham was an English writer, known for his plays, novels and short stories. Born in Paris, where he spent his first ten years, Maugham was schooled in England and went to a German university. He became a medical student in London and qualified as a physician in 1897. He never practised medicine, and became a full-time writer. His first novel, Liza of Lambeth (1897), a study of life in the slums, attracted attention, but it was as a playwright that he first achieved national celebrity. By 1908 he had four plays running at once in the West End of London. He wrote his 32nd and last play in 1933, after which he abandoned the theatre and concentrated on novels and short stories.
