Harry Bloch is a struggling writer who pumps out pulpy serial novels, from vampire books to detective stories, under various pseudonyms. But his life begins to imitate his fiction when he agrees to ghostwrite the memoir of Darian Clay, New York City's infamous Photo Killer. Soon, three young women turn up dead, each one murdered in the Photo Killer's gruesome signature style, and Harry must play detective in a real-life murder plot as he struggles to avoid becoming the killer's next victim.
