Two men have been murdered. Both of them were school bullies when they were younger. Plenty of people would have wanted them dead. A single clue has been found at the scene: a class photo from 1982, with two faces neatly crossed out.

Fabian Risk is the lead detective on the case. He's also one of the children in the photograph. As more people die, and more faces are crossed out, it becomes clear that a serial killer is targeting old classmates one by one. Fabian Risk thought he'd left his schooldays behind... Now he must confront his past if he is to find the killer before its too late.
