He’s going to kill you. He just doesn’t know it yet.
What would you do if you found a killer?
Would you run? Would you hide?
Or would you face your greatest fear?

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’s capable of so much more.

Profile K will kill again- and slowly, terrifying, 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…

The million- copy bestseller is back with a dark, terrifying journey into the kind of a killer that you won’t forget. The perfect read for fans of John Maris’ The One.
