High in the Welsh hills, a honeymoon getaway takes a dark turn when a rotting corpse is discovered in the rental property's bedroom.

In a dark, cold and damp December, DCI Evan Warlow and his team head out to investigate.

They find a victim who may not be as innocent as he first seems, and a rural community harbouring the worst kind of secrets.

When a second victim is attacked and a third goes missing, Evan knows he's up against a rogue killer with a Christmas list of his own.

And it's a deadly one.

Can he unmask the culprit before the season's festivities turn into a bloodbath?
