Pickax loves a big occasion. The Great Food Expo is about to begin, introducing new restaurants, country inns, food specialty shops and a new food page in the "Moose County Something." Lurking in the background is a killer determined to make this an event Pickax City will never forget.

The Expo begins with a literal bang: a bomb wrecks the hotel, killing a housekeeper and causing extensive damage. Luckily for Pickax, Qwill is on the scene, his moustache twitching with suspicions that this bomb was intended as something stronger than a warning to someone. His evidence: Koko and Yum Yum's new interest in cheese, especially Gruyere, Brie and Feta. Qwill and the Siamese are on a case that will demand all their feline intuition and mustachioed insight!
