Nikki's archaeologist friend Patrick becomes excited when a woman's body, apparently a thousand years old, is unearthed on a Yorkshire moor. However, dental records show she is a more recent murder victim and Leo, who once worked in the area, believes she is Jodie Fisher, a teenage girl who went missing in 1985. Three other girls were murdered at the time, and the killer, Karl Bentley, was caught and jailed. Leo decides to visit Bentley in jail, however, realises that the wrong man may have been jailed after a copycat killing is committed just hours later. Leo travels to Yorkshire, where he uncovers the identity of the fresh victim, Kelly Summers. He soon realises, however, that Bentley may have had an accomplice, and that his accomplice is still at large. This is confirmed when investigating officer Sonia Hardwick finds a letter to Bentley from his boyfriend in the original case file. Leo soon deduces that Bentley's male lover, Bill Fisher, may have been responsible for all of the murders.
