Eight years ago, psychologist Alex Delaware evaluated two teenage boys charged with the shocking murder of young Kristal Malley. Now one of the killers is out of prison - and wants to meet up with Alex. But by the time the pair do come face to face again, one of them is dead. Was Rand Duchay just another victim of an LA street crime? Or is something more sinister going on here? Alex and Detective Milo Sturgis mean to find out. To do so, they will follow a trail of blood that will lead them to the depths of cruelty - and straight to the heart of murderous betrayal. Jonathan Kellerman's gripping new psychological thriller brings to the fore all the elements that have made him an international bestselling author: page-turning plot, vivid characterisation and fascinating - often terrifying - emotional insight.
