All Sergeant Hamish Macbeth ever wants is a quiet life in the tranquil surroundings of Lochdubh, his home village in the Scottish Highlands. Although the area he polices is vast, he’s happiest when he’s working alone, yet the police authorities insist he has an assistant. In the past, they have supplied a variety of problematic misfits, but they surpass themselves with their latest effort – an American named James Bland. Having met Bland previously, when he was left in no doubt that the American led a life coloured by secrets and skulduggery, Hamish isn’t surprised when he discovers the real motive behind Bland’s police secondment involves him in helping track down a spy ring, some members of which have met grisly ends. That investigation tears Hamish away from Lochdubh at a time when the village is suffering a disturbing spate of increasingly violent burglaries.
