Two months later, Amy tells James that their swimming lessons are over, and they have a mission together. Overseen by mission controller Ewart Asker, they are to stay with Cathy Dunn at Fort Harmony, a hippy commune in Wales. There, they discover that brothers Fire and World Dunn are planning an anthrax attack against 200 oil executives and politicians, including the United States Secretary of Energy and the Deputy Prime Minister of the United Kingdom, at Petrocon, an oil conference held in the nearby Green Brooke Conference Centre. They successfully prevent the attack, although accomplice Brian "Bungle" Evans manages to escape. For his exemplary job in the mission, James is awarded a navy CHERUB T-shirt.
