Charlie Harris and his Maine Coon cat, Diesel, are embroiled in a new mystery when a cold case suddenly heats up in the latest installment of the New York Times bestselling series.
Charlie Harris is busy enjoying his new grandson when a mysterious man with a connection to Charlie´s family starts visiting the library, bringing with him troubling questions about an unsolved murder...
Charlie may be a proud new grandfather, but he and Diesel still have work to do at Athena College and the small Mississippi town´s public library. He´s too busy to deal with true-crime writer Jack Pemberton, who wants Charlie as the subject of his latest book--and who won´t take no for an answer.
A more appealing proposition for Charlie is spending time helping a kind, elderly man navigate the library´s genealogical database. But he´s shocked when he learns that the visitor´s search is focused on a member of his own family: his late aunt´s husband.
Charlie befriends the man and considers inviting him to stay in his home, but he´s soon given reason to question that notion. Jack is certain that Charlie´s new houseguest was involved in a shocking homicide that took place years ago in a small town near Athena. As this cold case heats up, Charlie and Diesel have to uncover a killer who may already be too close to home...
