Monsieur Pamplemousse and his trusty dog, Pommes Frites are called into Le Guide's offices early one morning and presented with a string of Leclercq's plaintive conundrums - all relating to his mobster uncle-in-law. These include a letter about a juicy steak turned brisket, a dead restaurant owner and a giant truffle delivered by post . With all these seemingly random problems at hand, Pamplemousse attempts to unravel each but it quickly proves impossible as they overlap and tangle at every turn - usually making him look the fool.
