Murder Past Due — Miranda James

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. Charlie'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. And by dinner, Godfrey's dead.

Now it's up to Charlie, with some help from Diesel, to paw through the town's grudges and find the killer before an impatient deputy throws the book at the wrong person. But every last one of Charlie's friends and coworkers had a score to settle with the nasty novelist. As if the murder wasn't already purr-plexing enough...
