The Big Sleep is a hardboiled crime novel by Raymond Chandler, the
first in his acclaimed series about detective Philip Marlowe. The
work has been adapted twice into film, once in 1946 and again in
1978. The story is set in Los Angeles, California. The story is
noted for its complexity, with many characters double-crossing each
other and many secrets being exposed throughout the narrative. The
title is a euphemism for death; it refers to a rumination in the
book about "sleeping the big sleep".
