When an Edinburgh serial killer is murdered in prison, his deadly legacy lives on to claim more victims in this “engrossing” Scottish detective mystery (Publishers Weekly).

For ten years, a gruesome Christmastime tradition terrorized Edinburgh. Each year as the holiday approached, a young woman’s body was found—naked, throat slit, body washed clean. The final victim, Kirsty Summers, was Detective Constable Tony McLean's fiancée. But the Christmas Killer made a mistake, and McLean finally put an end to the horror.

Now, 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 frightening explanation? McLean must revisit the most disturbing case of his life and discover what he missed before the killer strikes again.
