Lochdubh constable Hamish Macbeth's life is going to pot. He has—horrors!—been promoted, his new boss is a dunce, and a self-proclaimed traveler named Sean and his girlfriend have parked their rusty eyesore of a van in the middle of the village. Hamish smells trouble, and he's right, as usual. The doctor's drugs go missing. Money vanishes. Neighbors suddenly become unneighborly. The tension only explodes after the itinerant Sean is found brutally beaten to death...
The first message sent to Tom Thorne's phone was just a picture - the blurred image of a man's face, but Thorne had seen enough dead bodies to know that the man was no longer alive. But who was he? Who sent the photograph? And why? While the technical experts attempt to trace the sender, Thorne searches the bulletins for a reported death that matches the photograph. Then another picture arrives.
