Librarian Sherry Pinkwhistle keeps finding bodies—and solving murders. But she's concerned by just how many killers she's had to track down in her quaint village. None of her neighbors seem surprised by the rising body count...but Sherry is becoming convinced that whatever has been causing these deaths is unnatural. But when someone Sherry was close to ends up dead, and her cat, Lord Thomas Crowell, is possessed by what seems to be an ancient demon, Sherry realizes she is going to need an exorcist more than a detective. With the help of her town's new priest and an assortment of friends who dub themselves the "Demon Hunting Society," Sherry needs to solve the murder and get rid of the demon. This riotous book is a lesson for demons and murderers alike: Never mess with a librarian.
