James "Professor Puff" Henry may as well have "loser" stamped on his forehead. Divorced, overweight, shy, and living at home, he relies on books and his favorite snack -- cheese puffs -- for sweet relief from his problems. A former English lit professor William and Mary, he moves back to Quincy Gap, a small Virginia town in the Shenandoah Valley, to take care of his recently - widowed father. To improve his social life and waistline, he joins a supper club for dieters who lovingly call themselves the "Flab Five." Avoiding carbs is nearly impossible in this deep-fried potato-loving land, so a mysterious death in their small burg provides an effective, if disturbing, distraction. While dodging delectable temptations, Professor Henry and his fellow dieters work together to shed pounds and find the killer who has struck fear in this tight-knit community.
