DCI Kelso Strang is led to believe that something very odd is going on around the prosperous fishing port of Tarleton on Scotland’s south-east coast. Firstly, a young Detective Inspector is traumatised after witnessing a doctor throwing herself off a cliff, and accusations of extortion have riven the local community.

And when the ugly death of a young farmer sets off a murder investigation, Strang finds himself caught in a spider’s web of criminality. He is entirely unprepared when he is struck by the worst tragedy of his career, even though it has also brought him into contact with a young advocate’s assistant called Catriona, daughter of DI Marjory Fleming.
