Steven Parnell, who was accused of murdering a number young girls the previous summer, is killed while in prison awaiting trial. Morse had not been involved in the case as he was on leave during most of that investigation. What piques Morse's interest is that one of the victims, Karen Anderson, was never found and it is assumed that her body was dumped in a nearby lake but Parnell confessed to his priest on his deathbed that he wasn't responsible for that particular murder. When one of the witnesses in the case, George Daly, is murdered, Morse and Lewis try to find some connection to Anderson's disappearance. They also wonder why Anderson's camera - she was an avid photographer - wasn't found. What they come across is a group of middle-aged men whose hobby is taking so-called glamour photos.
