In August 1940, in compliance with the Führer's directive on the imminent invasion of Britain, the Gestapo prepared a secret handbook to be distributed to the occupation forces. It offered an astonishing insight into exactly how the Nazis perceived Britain and her empire, offering detailed analyses of the political and economic structure of the country, with chapters covering everything from Parliament and public schools to freemasonry and the Boy Scouts. The chapter on British Intelligence was considered so embarrassingly accurate that the few copies retrieved at the end of the war were retained by the authorities. It is only now, more than half a century later, that a translation has been made, revealing the full and remarkable truth.
