After losing her job of 23 years, Mabel decides to launch what will surely be a glamorous new career as an author. Having recently inherited her late grandmother’s house, she has the freedom to spend time volunteering and writing about her experiences.

Everyone in Athena, Mississippi, knows Charlie Harris, the good-natured librarian with a rescued Maine coon cat named Diesel that he walks on a leash. He's returned to his hometown to immerse himself in books, but soon enough he's entangled in a real-life thriller. A famous author of gory bestsellers and a former classmate of Charlie's, Godfrey Priest may be the pride of Athena, but Charlie remembers him as an arrogant, manipulative jerk—and he's not the only one. Godfrey's homecoming as a distinguished alumnus couldn't possibly go worse: by lunch, he's put a man in the hospital.

With the Mississippi sun beating down, An'gel and Dickce are taking a break to cool off and pet sit their friend Charlie Harris's cat, Diesel, when their former sorority sister, Rosabelle Sultan, shows up at their door unexpectedly, with her ne'er-do-well adult children not far behind. Rosabelle's selfish offspring are desperate to discover what's in her will, and it soon becomes clear that one of them would kill to get their hands on the inheritance.

Holly Miller's life has gone to the dogs. She has no job, her boyfriend's former flame is sniffing around, and a scruffy but lovable Jack Russell terrier is scattering crumbs all over her borrowed car. Just when she thought things couldn't get worse, a troubling phone call about her grandmother sends her rushing home to the family inn on Wagtail Mountain.

When she moved to Stoneham, city slicker Tricia Miles met nothing but friendly faces. And when she opened her mystery bookstore, she met friendly competition. But when she finds Doris Gleason dead in her own cookbook store, killed by a carving knife, the atmosphere seems more cutthroat than cordial. Someone wanted to get their hands on the rare cookbook that Doris had recently purchased-and the locals think that someone is Tricia.
