One killer was bad enough. Now they're two.

After famously stopping a serial killer, Detective Cade Dawkins thinks the worst is behind him. He’s wrong.
A disturbing discovery reveals a dark-web forum where serial killers gather to boast, share exploits, and issue challenges. When a challenge is issued to outsmart the detective who stopped one of their own, killers descend on Minnesota, turning murder into a game and Cade into the prize.

With two killers from the site terrorizing the public, the media turning on him, and the governor threatening to fire him, time isn’t Cade’s friend. But then, neither are the serial killers.
