The small town of Yarrow Glen's neighbor, Lockwood, hosts an annual Labor Day weekend bash: Dairy Days. And Willa Bauer and her cheese shop, Curds & Whey, refuse to miss out on the fun. Willa is thrilled to celebrate her favorite thing--she is a cheesemonger after all--and this festival goes all out: butter sculptures, goat races, cheese wheel relays, even a Miss Dairy pageant. Too bad the pageant runner, Nadine, is treating Dairy Days prep like it's fondue or die and is putting everyone around her on edge. When Willa finds Nadine's dead body under years' worth of ceramic milk jugs, the police aren't sure whether the death was an accident. But fingers are pointing at Willa's employee, Mrs. Schultz, who steps in to help the pageant after Nadine's death. Someone wanted Nadine out of the whey, and Willa is going to find out who.
