In bleak midwinter, the people of Shipcott are shocked by the murder of an elderly woman in her bed. As snow cuts off the village, local policeman Jonas Holly is torn between catching a brutal killer and protecting his vulnerable wife, Lucy.
When the inquiry is commandeered by an abrasive senior detective, Jonas finds himself derided by his colleagues and ashamed to admit to Lucy that he's been sidelined. It seems his first murder investigation may be over before it's begun. But when he receives a series of increasingly sinister anonymous notes, Jonas is thrust back into the center of the case. Someone in the village is taunting him, blaming him for the tragedy. Someone thinks he's not doing his job; someone seems to know every move he makes. And soon Jonas has to ask: Who's hunting who?
