Double-Cross System

The Incredible Story of How Nazi Spies Were Turned into Double Agents


Book Description

The classic account of how British intelligence penetrated and practically operated Nazi Germany’s spy network within the British Isles

With great imagination, care, and precise coordination, the British were able to identify Nazi agents, induce many to defect, and supply completely false information to Germany about bombings, battles, and even the D-Day invasion. Told by the man who masterminded the entire, unbelievable four-and-a-half-year scheme, and filled with extraordinary stories and dazzling tidbits, The Double-Cross System is a testimony to Britain’s skill in the fine art of counterespionage.


Sir John Masterman served as provost of Worcester College at Oxford and vice-chancellor of Oxford University before his work with British Intelligence during the Second World War. He is also the author of severaly mystery books, including An Oxford Tragedy, Fate Cannot Harm Me, and Marshall Ney.
