Make Peace Not War

Three young boys break into a warehouse, but are disturbed by the owners. One of the intruders, Ziggy, manages to escape. He turns out to be another of Makepeace's informants. Dempsey goes undercover as an American drug dealer in London, who is meeting with Merle and her chauffeur, Davros. Dempsey is taken to Merle's warehouse, which turns out to be the same warehouse where Ziggy escaped from. While Dempsey was at the warehouse, Makepeace walks in and almost blows Dempsey's cover.
