The Big Sleep is Raymond Chandler's classic hardboiled detective novel featuring private investigator Philip Marlowe. Hired by wealthy General Sternwood to handle a blackmail case involving his wild daughter Carmen, Marlowe becomes entangled in a complex web of murder, pornography, and deception. As bodies pile up—including the mysterious disappearance of Rusty Regan, the General's son-in-law—Marlowe navigates Los Angeles's criminal underworld, encountering gamblers, gangsters, and femme fatales, particularly the seductive Vivian Regan. Through smoke-filled rooms and moral ambiguity, Marlowe relentlessly pursues truth despite pervasive corruption. The 1939 novel established Chandler as a master of crime fiction, defining the hardboiled genre with its atmospheric prose and cynical worldview.
