Eight years ago two young boys killed a younger child. Alex Delaware was asked to evaluate them by the judge to see if they should be tried as adults. The case was resolved with a plea bargain - the younger of the boys was killed shortly after being sentenced. The other boy is now out and has called Alex wanting to talk to him. By the time Alex gets to the meeting point he's nowhere to be seen. Then Detective Milo Sturgis calls - a body has been found. The ensuing investigation leads to all kinds of theories but they narrow their focus to one man and what he's been doing sickens them both. Another enjoyable read in this series by Jonathan Kellerman.
