Spring has come to charming Mayville Heights, and with it, some Hollywood glamour. The little town is abuzz because the reboot of a popular baking TV show is filming there. Librarian Kathleen Paulson is working as an advisor on historical facts for the show, local restaurants are providing catering for the camera crews, and Kathleen's faithful felines, Hercules and Owen, are hoping there is a cat treat challenge. But then Kathleen finds one of the judges dead. She has solved many-a-murder with help from the supernaturally gifted Herc and Owen, and with the whole town on tenterhooks, the talented trio will have to have all paws on deck to chase down this killer.
