Why Raymond Chandler’s most famous novel leaves its central mystery completely unsolved

In short: Raymond Chandler’s 1939 debut, The Big Sleep, redefined detective fiction with its cynical atmosphere and laconic investigator, Philip Marlowe. Yet, beneath its hardboiled exterior lies a narrative so complex that even its author could not explain who killed the chauffeur. It remains a masterpiece of style over perfect plot coherence.

Published in 1939, The Big Sleep introduced Philip Marlowe, a private investigator navigating the moral disorder of 1930s Los Angeles. Chandler, who began writing fiction after losing his oil company job in 1932, crafted the novel by 'cannibalizing' his earlier pulp stories, specifically 'Killer in the Rain' and 'The Curtain'. By merging these independent narratives, he created a sprawling, atmospheric work that prioritized characterization and mood over the rigid plot structures favored by his contemporaries.

The novel’s plot is famously tangled. When Howard Hawks directed the 1946 film adaptation, his writing team was baffled by the identity of the chauffeur's killer. Chandler admitted he had no idea, illustrating his belief that a compelling atmosphere mattered more than tying up every loose end. This approach drew criticism from peers like Ross Macdonald, who argued that a novel’s structure should be intentional and singular, but it cemented Chandler’s reputation as a master of the genre.

Set against the backdrop of the Great Depression and the rise of mass culture, the book reflects the era's cynicism. Marlowe serves as a lone wolf of the old guard, struggling against a world where traditional social norms were rapidly eroding. While initial reviews were mixed—with some critics dismissing it as mere 'drugstore literature'—the novel eventually gained status as a high peak of the hard-boiled genre. Today, it is widely recognized as one of the most influential books of the 20th century, celebrated not for its mystery, but for its evocative prose.
