John Keswick followed his brother to the far east in 1929 and replaced him in Shanghai after the shooting incident. Like his brother, John Keswick worked for the Special Operations Executive (SOE) alongside Nationalist leader Chiang Kai-shek's spy chief General Dai Li in Chongqing. He fled Shanghai when the Japanese took the city, escaping with his wife Clare to Ceylon (Sri Lanka) and served during the war with Admiral Lord Louis Mountbatten's staff.
