One year after Yvonne Harrison was killed, the police received an anonymous letter accusing the thief Harry Repp who was about to be released from prison. Deputy Director Strange handed the case to DS Lewis, who was waiting to be promoted to inspector. Morse is ill and has just returned to work. He involved himself in this case, which caught Lewis off guard, but with the increase in the number of corpses, Morse found himself responsible for investigating a woman who had multiple extramarital affairs with many different men. When he learned that the deceased had a large amount of cash on his body, he suspected that they were blackmailing her killer.
