The Double-Cross System in the War of 1939 to 1945

Written at the war's end and first published in 1972, this official history explains how British intelligence identified German agents in the United Kingdom, turned many of them, and ran them as a coordinated double-cross. Masterman, who chaired the Twenty Committee, describes the recruitment and control of agents, the traffic of false reports to German handlers, and the use of that channel to protect Allied operations, including the deception covering the 1944 invasion of France. Named cases show how a captured spy became a long-term instrument. The book is an institutional account of counter-espionage, not a novel of spy craft.
