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 Pickac 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 moustace 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 the case that will demand all their feline inutition and mustachioed insight!
