"L'Étranger," written by Albert Camus, is a novel that explores themes of absurdism and existentialism. The story follows Meursault, a detached and emotionally indifferent man, who becomes embroiled in a murder trial after killing an Arab man. His lack of conventional emotions and societal norms leads to his alienation from society. The novel is divided into two parts: the first focuses on Meursault's life and relationships, while the second centers on his trial and the philosophical implications of his actions. Through Meursault's experiences, Camus examines the nature of existence and the search for meaning in an indifferent universe.
