Juan Pujol Garcia was perhaps the most important spy from WWII. As Agent GARBO, he walked into the innermost circles of the Third Reich, earned the Nazis’ trust, and fed them a pack of lies. His tour de force: persuading the Germans of a fabulously fake Allies battle plan for D-Day that diverted their troops and made the Normandy landings a success. A Spanish chicken farmer turned double agent, he tricked the Nazis, fooled his own wife, and helped the Allies win the war.
