A coach's retirement, a stranger's arrival and deadly practical jokes cause Jessica to re-examine a 20-year-old murder.

Jessica arrives at a convent to visit an old college friend who is now a nun. While enjoying their visit, the pair soon gets caught up in a murder investigation when a fellow nun, who is the convent's unofficial record keeper is found dead of an apparent suicide. At her friend's urging, Jessica promises to get to the bottom of what happens and soon discovers that her death is connected to a young woman who sought refuge at the convent years ago, her dying father, and the city's mayor and his wife.
