Overview: A black pearl on which Lupin has set his sights is stolen just ahead of him by... a gang of three gorillas?! What would gorillas want with jewels? Lupin thinks, while setting up a decoy plan. When the gorillas next appear, they take both the jewels he set out from them, and Fujiko as well. This scene smells of a put-up job... That guardian of justice, Zenigata, doesn't give up either!
