Killer with a Key is a hardboiled crime novel from Dan J. Marlowe, a writer whose lean, violent fiction helped define the darker edge of mid-century American suspense. A man with a criminal past, a woman in danger, and a key that may unlock more than one secret pull the story into a world of pursuit, mistrust, blackmail, and murder. Marlowe's strength is pressure: his characters move through a landscape where greed, fear, and desperation strip away respectable surfaces and leave only risk.
First published in the late 1950s, Killer with a Key belongs to the world of paperback noir, hardboiled mystery, and American crime fiction in which survival often depends on nerve, suspicion, and the willingness to act first. For readers of vintage crime novels, noir fiction, private-eye-era suspense, paperback originals, and mid-century mystery fiction, Marlowe offers the directness and menace that made his work a lasting part of the hardboiled tradition.
