When the body of social worker Simon Judd is found between two cars in a pub parking lot, the scenario is eerily similar to that from the unsolved murder of Trevor Philpott six years earlier. As DCI David Webb starts investigating the Judd case, he hopes that the new case will shed some light on the earlier one.
Meanwhile, it turns out that criminologist Frederick Mace has been researching the Philpott case for a chapter in a forthcoming book, a book showing how often violation of one or more of the Ten Commandments lies behind serious crimes. Mace has his own theories about how the Philpott and Judd cases may---or may not---be related, and he has some new information on the Philpott case. Will his research help, or hinder, the police investigation? Will he beat them to the solution of the Philpott case?
This is the 14th book in the David Webb series, and one of my favorites. As usual, there is an interesting cast of characters and a complex mystery.
