Detective Mike Nash is going to have a very unmerry Christmas.



In an ordinary terraced house, a family dies. Poisoned by carbon monoxide. Then comes a suspicious house fire, with more bodies at the charred scene. A drug addict is murdered in the most bizarre medieval manner. And a scientist’s daughter disappears.



There's a killer on the loose this holiday season. DI Mike Nash follows the leads of these disparate crimes. One very dangerous person seems intent on revenge.



Can he stop the killer before anyone else pays the ultimate price?
