The short version

General Sternwood hires Philip Marlowe to deal with blackmail involving his daughter Carmen. The detective finds a murdered bookseller, compromising photographs, and further deaths that complicate the apparently limited job. Sternwood's other daughter Vivian tries to close the investigation while drawing Marlowe toward her. His search reaches gangster Eddie Mars, whose control over the family depends on a hidden story about the missing Sean Regan. Vivian eventually helps Marlowe escape Mars's gunman. He turns the gangster's planned ambush against him and protects Carmen from the public account.
