In the mid 1970s Wakeman began to focus on the history of Shanghai. Best known of these works are the "Spymaster: Dai Li and the Chinese Secret Service", and his "Shanghai Trilogy": "Policing Shanghai, 1927–1937"; "Shanghai Badlands, 1937–1942", and "The Red Star Over Shanghai, 1942–1952" (posthumously published in Chinese).
