Author Heinrich Pfeifer joined the Nazi spy service as a German nationalist and Catholic before Himmler and Heydrich had moved to Berlin. He later became disgusted by the anti-Semitism, the concentration camps, the murders and corruption, and what he called the "satanic" character of Heydrich. He defected in September 1938 and lived in fear of his life until his assassination in 1949, having exposed many Nazi agents and assisted many intelligences agencies prior to and during World War Two. He made a major contribution to the Allied War Effort, which has never been known until now. Editor Robert Temple is a well-known author, historian, and historian of science in England.
