This book by Theodor Gladkov – famous historian and writer, author of many books about the life and work of spies – is once again about a person who was a part of this unique service. Willi Lehmann was veteran of the Nazi Party, captain in the Gestapo, overseer of Germany’s military defense industry. This was the very same Soviet foreign intelligence agent А/201, Breitenbach, who for 12 long and terrifying years provided Headquarters with invaluable information about the development and growth of the fascist regime, the large-scale preparations for world supremacy, the active buildup of military forces and of new technical developments. The book that you are holding in your hands has no fictive elements made up by the author. On the contrary, it contains hard facts about an amazing person’s incredible story, which only had its highly classified stamp removed in June 2009.
