Ten years after the publication of his Services Spéciaux (1935-1945), Paillole took up his pen once again in order to shed further light on the critical role that the French Secret Service played in the infiltration of German agencies. In this first English edition of The Spy in Hitler’s Inner Circle, Paillole brings us to the very heart of the world of espionage and counterintelligence, providing unique insight into the key figures that led to the decoding of the Enigma machine at Bletchley and the ultimate collapse of Hitler’s Third Reich, most notably through Hans-Thilo Schmidt, France’s German spy embedded in the very heart of the Third Reich. In compelling narrative style Paillole details how Schmidt delivered intelligence to France right from the source of the German Cipher Office. Schmidt, whose brother Rudolf occupied one of the highest postings in the Third Reich, commander of 2nd Panzer Army in Russia, created an intelligence network between France, Poland and England, and successfully transmitted crucial details about Hitler’s strategic plans. From information about Germany’s rearmament and the reoccupation of the Rhineland, to fundamental technical intelligence about the Enigma machine, Schmidt’s contributions are key to the Allied victory in the intelligence war, despite the fact that France largely ignored his communications.
