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, Hicks immediately turns his attention to the most likely culprit - her possessive ex-husband. But when a second body is found, similarly beaten, Hicks is forced to think again about his suspect. As the death toll starts rising, Hicks realises he's dealing with something much darker - and deadlier - than he'd imagined. A serial killer is at large - one who revels in chaos. To stop the senseless murders, Hicks must bring the killer to justice. But will his own demons stand in the way?
