Season 5

A local clergyman is anxious to re-open a thirty-year-old murder case, which resulted in Harry Painter being hanged for the axe-murder of an elderly woman. Wexford himself, as a young detective sergeant, helped to convict Painter, and he has to face the possibility that the wrong man was hanged.

Wexford is staying in London with his nephew Howard, a police superintendent, convalescing from over-work and under doctor's orders to drink only water. He is supposed to be resting, but he is bored, and his nephew is dealing with a fascinating murder case. The body of a young woman, Loveday Morgan, was found in Kenbourne Vale Cemetery, strangled with a silk scarf, and the only things in her handbag were a photograph and two telephone numbers. It appears that she had no money and was living under a false name. Wexford, keen to get out and about, is drawn to the case. His unofficial investigation uncovers a story of adoption and parental love.

Wexford assumes that one of these men is Doon, and was having an affair with the victim, but appearances can be deceptive
