Perils and Potions - Evans S. Usher

The annual Pigsend Harvest Festival is coming up quick, and Bev's been assigned to the planning committee against her will. But Ida Witzel, the festival chair, wants no mishaps this year, and she knows if Bev's involved, the hijinks will be at a minimum. That is, until farmer Trent Scrawl isn't seen for a few days, and on a wellness visit, Bev finds him dead.

Well, not dead, but in a mysterious magical coma. While Doc Howser scours the countryside for the antidote, Bev's once again called in to investigate. The obvious culprit is Trent's nemesis Herman Monday, but when another prominent Harvest Festival entrant goes down, it becomes clear the mystery is bigger than petty pumpkin squabbles. Can Bev figure out who's trying to ruin the Harvest Festival before it's too late? 

Perils and Potions is the ninth book in the Weary Dragon Inn series.
