Once again Sammy the cat, not only literally sniffs out a mystery but also has a paw in saving the day. It's Cranberry Festival time in Center City and, as is the case every year, Farmer Greene has supplied corn shocks to all the businesses to decorate as they see fit. Gayle Schwartz, owner of the Hammerin' Nails, and her boyfriend, Detective Dave Landis, have just strategically placed the corn shocks when Sammy begins pawing at one. What he uncovers is not a mouse as Gayle thought, but a human big toe. Almost before the second toe appears Dave is informed that calls are coming in from all over town that more suspicious "pieces" of something are appearing. Once the victim is identified, this small town yields an almost unlimited number of suspects and soon Dave, Gayle, and Sammy find themselves faced with more than one mystery.
