Three bodies have been found in less than three weeks. This is more than Detective Dawson Falco has seen in all his years on the Omaha PD Homicide Division. The victims appear random, with different ages, genders, and races. And the crimes all occurred at different locations and used different weapons. The only similarity is that the victims were last seen with a thin man wearing black. Despite the flimsy connection, Dawson can't shake the thought that a serial killer is stalking his city.

Dawson's wife, Harper, is proud of her husband's career, but her own career is just as important. Harper is the head chef and owner of one of Omaha's trendiest restaurants. She's also writing her first cookbook, which Dawson promised to help her with. He's repeatedly broken that promise because of his case. Worse, he's lied to her about it.

As the case consumes Dawson, he finds himself doing the one thing he always promised to never do: put Harper and her career second to an investigation. He knows she's getting close to her deadlines, and that he's not getting any closer to solving the case. He just needs one last clue, one last piece of the puzzle to catch a murderer. When he does, will it be too late for him and Harper?
