Hazel Wallace returns from her training, as the new Detective Sergeant, and is put to work by Supt Mullett sorting out the mess left behind by DI Frost, while he is on extended compassionate leave. Before long she is called upon, when a man is found hanged in his home, and she suspects it was not suicide. Routine investigations show that a fresh set of fingerprints at the scene belong to an unidentified man who had been found drowned a year previously. Frost is summoned back by Supt Mullett to sort things out, and he connects a painting that appears to have been stolen from the hanged man with an art robbery & murder some years before.

A woman is found in a critical condition in a quiet village on the outskirts of Denton, a victim of an apparent hit-and-run incident. Her husband and daughter are distraught. Frost's investigation exposes the secret life of a corner of rural England.

Frost is called upon by Supt Mullett to investigate the theft of his friend's car from their golf club by a confidence trickster, who leaves behind a trail of satisfied golfing widows, unpaid bar bills and stolen cars. It gets complicated when the car is recovered with the body of a local drugs dealer in the boot. What are the connections between the car owner, the con-man and the dead drug dealer?
