The annual Billy Goat Gruff Festival is the undisputed highlight of Hernia's social calendar. But when Magdalena Yoder, village mayor and owner of the PennDutch Inn, had the brainwave four years ago, little did she realize that it would soon attract visitors from far and wide - even Australia, as the unexpected arrival of Gabe's long-lost cousin, Miriam, at the inn confirms. Unfortunately, the shock of Miriam's one-legged appearance is soon usurped by a gruesome discovery, followed by a series of bizarre pranks as the festivities take place. As chaos ensues, Magdalena is spurred into finding a killer. But is the festival really the target, or is it Magdalena herself?
