Sami Kierce, a young college grad backpacking in Spain with friends, wakes up one morning, covered in blood. There’s a knife in his hand. Beside him, the body of his girlfriend. Anna. Dead. He doesn’t know what happened. His screams drown out his thoughts—and then he runs. Twenty-two years later, Kierce, now a private investigator, is a new father who’s working off his debts by doing low level surveillance jobs and teaching wannabe sleuths at a night school in New York City. One evening, he recognizes a familiar face at the back of the classroom. Anna.

Sydney Shaw, like every single woman in New York, has terrible luck with dating. She’s seen it all: men who lie in their dating profile, men who stick her with the dinner bill, and worst of all, men who can't shut up about their mothers. But finally, she hits the jackpot. Her new boyfriend is utterly perfect. He's charming, handsome, and works as a doctor at a local hospital. Sydney is swept off her feet. Then the brutal murder of a young woman—the latest in a string of deaths across the coast—confounds police. The primary suspect? A mystery man who dates his victims before he kills them.
