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.
Margaret Parsons, a fairly ordinary housewife who, with her water board official husband Ron, has recently moved to Kingsmarkham, is found murdered in a field. Mrs. Parsons led an extremely uneventful life, being a lay preacher, but Inspector Wexford is intrigued when he is looking through her belongings and fine a number of expensive antique books all inscribed 'From Doon to Minna'.Who is Doon?
Although Mr. Parsons is under the impression that he and his wife knew nobody in Kingsmarkham it turns out that Margaret had two school acquaintances in the town, Helen Missal and Fabia Quadrant, who are now both married to very wealthy men. Wexford assumes that one of these men is Doon, and was having an affair with the victim, but appearances can be deceptive
