For DI Andrew Hicks, solving a murder is logical: your first suspicions are usually right. So when the brutally beaten body of a young woman is found, his attention focuses closely on the ex-boyfriend. But then more bodies start appearing, all beaten beyond recognition, and there is no connection between any of the victims. Because this is a new type of killer, one who revels in chaos. To survive, Hicks must face not only a serial killer with no discernable motive, but the hidden darkness of his own past.
