Which author wrote 'The Long Goodbye'?

The author who wrote The Long Goodbye is Raymond Chandler.

Published in 1953, it is Chandler's sixth novel featuring Philip Marlowe, the private investigator who navigates corruption, wealth, addiction, and betrayal in Los Angeles. The story begins with Marlowe's friendship with Terry Lennox and gradually expands into a broader investigation involving a missing writer and a wealthy family.

The novel is more introspective than many earlier hard-boiled mysteries. Chandler uses Marlowe's investigation to criticize social hypocrisy and explore loyalty, loneliness, alcoholism, and the uneasy boundary between friendship and self-interest.

Chandler reportedly called it his best book. The novel won the Edgar Award for Best Novel in 1955, and Robert Altman's 1973 film adaptation moved the story into contemporary Los Angeles, with Elliott Gould playing Marlowe. It is sometimes confused with Ross Macdonald's Lew Archer novels, but Macdonald did not write it.
