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 seem random, with different victimology, location, and weapons. The only similarity is that the victims were last seen with a thin man wearing all black. Despite all the evidence, Dawson can't shake the thought that there is a serial killer stalking the city. At home, Dawson's wife, Harper, is starting to feel like her career is less important than Dawson's. She is the head chef and owner of one of Omaha's trendiest restaurants, and she is writing her first cookbook. Dawson promised to help her by reading the introductions to her recipes, but he hasn't. Worse, he's lied to her about it. As the case consumes Dawson, he finds himself doing the one thing he always promised himself he would 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?
