Midnight Jones is an analyst trained to understand the human mind. But everything changes when, in the course of her work, she discovers Profile K’s file – because K stands for killer, and she knows that someone more dangerous than she could have ever imagined walks among them.

Midnight knows what Profile K is capable of before he even commits his first crime. But as the news rolls with the brutal murder of a local woman, no one believes what she tells them: that he is capable of so much worse.

Profile K will kill again – and, terrifyingly, Midnight realises that the moment she found his file was the moment she became his next target. Because Profile K is coming for Midnight – and the only way to escape with her life is to find him before he finds her.
