When Jessica learns from Phyllis Thurlow that her dear friend, journalist and writer Daniel Hannigan, has died, she decides to continue his research into what he had told her was the wrongful imprisonment of a man who has been in jail for 16 years. The man in question is Phyllis' brother, Martin Thurlow, who was convicted of killing his wife, Lydia. Daniel was convinced that the murderer was in fact Lydia's brother, Eric Grant. Grant's father is a power in town but Jessica gets good support from the Deputy Police Commissioner, Bradley Folkes. She comes to believe that Martin Thurlow is innocent but isn't convinced Grant is guilty. A bullet worn as a pendent is the vital clue that leads her to solve the mystery.
