Technically speaking, The Big Sleep is Frankenstein’s monster. Published in 1939, it had been assembled by Raymond Chandler out of two short stories: ‘Killer in the Rain’ (1935) and ‘The Curtain’ (1936). That might be the reason why The Big Sleep is not as accurately structured as a Christie novel, famously leaving out the answer to who killed the chauffeur. When Chandler was asked that question by Howard Hawks, whose writing team was working on a film adaptation of the novel, the author replied that he had no idea.
