Following gangsters, blackmailers, and gunmen through the underbelly of 1930s America on their journeys to do dark deeds, Paul Cain's stories are classics of his genre. The protagonists of ambiguous morality who populate Cain's work are portrayed with a cinematic flair for the grim hardness of their world. Fast One, Cain's only novel, was originally serialized in Black Mask in the 1930s. It introduces us to Gerry Kells, a hard-nosed criminal who still holds fast to his humanity in a Los Angeles that's crooked to the core.
