Every year for ten years, a young woman's body was found in Edinburgh at Christmas time: naked, throat slit, body washed clean.
Ten years, ten women.
The final victim, Kirsty Summers, was Detective Constable Tony McLean's fiancee. But the Christmas Killer made a mistake. In a cellar under a shop, McLean found a torture chamber and put an end to the brutal killing spree.
Twelve years later, and 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?
McLean must revisit the most disturbing case of his life and discover what he missed before the killer strikes again...
