《이방인》, or "The Stranger," is a novel written by French author Albert Camus. Published in 1942, it tells the story of Meursault, a detached and indifferent man who becomes embroiled in a murder trial after killing an Arab man. The novel explores themes of absurdism, existentialism, and the nature of human existence. The narrative is divided into two parts: the first focuses on Meursault's life and his emotional detachment, while the second deals with the consequences of his actions and the societal reactions to his behavior. Through Meursault's experiences, Camus examines the conflict between individual freedom and societal expectations.
