Hitler, Churchill, Montgomery and Eisenhower all used 'doubles' during WW2. Most instances have never been publicised. Black Masquerade tells of just one such event executed in the early days of the war and of which there are 'no' official records (or at least none of which are available) Why? Politics and secrets. Intelligence, when undertaken with intelligence, can be a very dangerous 'game'. When not - even more catastrophic. When as successful as 'Operation M' it was small wonder it is still kept 'under wraps'. You be the judge.
