Explanation:

The Outsider" (or "The Stranger" in some translations) is a novel by Albert Camus, published in 1942. It tells the story of Meursault, a detached and apathetic French Algerian who becomes embroiled in a senseless murder and subsequent trial. The novel explores themes of existentialism, absurdity, and the alienation of the individual in society. Camus's philosophical exploration in "The Outsider" remains influential in existentialist thought.
