How did the British intelligence services influence the transition of power during the decline of the British Empire? Calder Walton, a historian specializing in intelligence and security, utilizes recently declassified MI5 records to argue that intelligence operations were a critical, often overlooked component of Britain's post-war decolonization strategy. By examining the intersection of Cold War anxieties and colonial administration, the author demonstrates how intelligence agencies managed the risks of Soviet subversion while facilitating the transfer of sovereignty to new national states.

The work is regarded as a significant contribution to the study of British imperial history, noted for its rigorous use of primary source material to fill a gap in the historiography of the post-war era. The text provides a dense, scholarly examination of the intersection between clandestine operations and statecraft, making it a valuable resource for specialists in intelligence history and colonial studies.
