The Big Sleep (1939) 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 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", and is not descriptive of the plot.
In 2005, Time magazine included the novel in its 100 Best Novels published after 1923 Summoned by the dying General Sternwood, Philip Marlowe is asked to deal with several problems that are troubling his family. Marlowe finds that each problem centers about the disappearance of Sternwood's favoured employee who has left with a mobster's wife. Each of the problems becomes a cover for something else as Marlowe probes.
