Val Adair is promoted to Detective Superintendent and transfers to Dorset. Immediately she has to contend with two drug users found dead in a tent, but is it a drugs overdose or is it murder? Then there are a series of burglaries and thefts at rural locations on an almost epidemic scale, and Adair has to work closely with neighbouring Forces to try and find those responsible. A female Russian Agent is clandestinely smuggled into Dorset, but who is she and what is her goal, seeing as how her speciality is the art of seduction. When a man is found shot dead on a coastal footpath, closed during an Army live firing exercise, Adair investigates and finds herself working with Special Branch to try and find the Russian. Follow the chase as the hunt gradually closes in to its cliff hanging conclusion.
