The Gestapo is widely regarded as the most dreaded organization of the Third Reich, yet the very name of its commander has curiously been erased from the pages of history. As director of Section IV (Gestapo) of the Reich Security Headquarters, Heinrich Müller reported directly to Heinrich Himmler and Reinhard Heydrich.

At first operating only on German soil, Müller eventually exercised power over all of Occupied Europe. Assisted by a grimly talented staff, of which Adolf Eichmann became the most famous, Müller was eventually responsible for the deaths of millions of Jews, prisoners of war, and citizens of the various occupied countries. On April 29, 1945, Heinrich Müller walked out of Hitler's bunker and disappeared off the face of the earth. During the long Cold War that followed, the Americans and Russians could agree on very little, but they agreed on one thing: Heinrich Müller never existed.

Drawing on international contacts he developed during previous studies of Bormann, Peiper and Heydrich, Charles Whiting now takes on the greatest unsolved mystery of the Third Reich: The true role and subsequent whereabouts of Heinrich "Gestapo" Müller. The few experts who would admit to knowing his name offered contradictory assessments that sound suspiciously like a smokescreen. Müller is dead; he is alive; or he is not only alive but has written three volumes of memoirs. He is in Buenos Aires, Rio de Janeiro, Moscow, Langley, or Damascus. He was working for the West all along, or the Russians, or he was exactly what he appeared to be. World War II veteran and tireless researcher Charles Whiting unravels at last a 50-year-old mystery and cover-up.
