Every year for ten years, a young woman’s body was found in Edinburgh at Christmas time: naked, throat slit, body washed clean. The final victim was Detective Constable Tony McLean’s fiancée. But the Christmas Killer made a mistake, and McLean put an end to the brutal killing spree. Twelve years later, a fellow prisoner has just murdered the incarcerated Christmas Killer. But with the arrival of the festive season comes a body. A young woman: naked, washed, her throat cut. Is this a copycat killer? Was the wrong man behind bars all this time? Or is there a more sinister, frightening explanation?
