Returning to the scene, John and Beth Cunningham, owners of the Three Oaks Kennels, find what appears to be the only clue: a terrified cocker spaniel abandoned at the roadside. As the police, still reeling from a gruesome local murder a few days previously, arrive to investigate, events take a sinister turn. Tell-tale traces of blood are found on John’s business partner’s Land-Rover. In desperation, he begs John to clear his name. But what starts as a favour for a friend soon becomes something a great deal more frightening: a confrontation with a ruthless psychopath who’ll do anything to cover his tracks...
