Whether chasing hoodlums or solving impossible murders, Dashiell Hammett’s Continental Op is one of the toughest detectives in the history of crime fiction The Continental Op is going over his expense reports when a raw-boned man staggers through the door of his office, stretches out his arms, and dies. As the stranger falls to the floor, he utters a final word: Hell. It’s apt, because this man’s death will drag the Op right into the inferno. The contents of the man’s pockets are enough to send the Op off in search of his identity, his connection to San Francisco, and the treacherous underworld dealings of both the victim and his killers.   The Continental Op made his name taking punches and dodging bullets, but unraveling “The Creeping Siamese” is the kind of mystery that will baffle even him. This story, along with “The Big Knock-Over” and “$106,000 Blood Money,” is a testament to the enduring genius of Dashiell Hammett.
