Ripe For Revenge by Janie Bolitho (DCI Roper #3)

During the hot summer holidays, the quaint village of Little Endesley is rocked to its roots when the body of a young girl is found in the woods. Suspicion immediately falls on Jacko Penhaligon, a family man with an unfortunate history of child molestation. But Detective Chief Inspector Ian Roper reaches beyond the obvious. The absence of clues seems to indicate a random killing—a passerby who killed for unknown reasons. Some pornographic videos may or may not have any relevance, though they do offer a surprising star. Ironically, some seemingly unconnected crimes provide Roper with the solution: a vendetta as old as tragedy—and a killer willing to wait until his victims are ripe for revenge.
