Juan Pujol, a young Spanish antifascist, became agent GARBO, a master of deception and intrigue. His story contains all the hallmarks of classic spy adventure - enciphered messages, secret inks, items concealed in cakes - culminating in one of the greatest strategic deceptions in history. Through a ring of invented subagents, GARBO and his MI5 controllers succeeded in convincing the Germans that the DDay landings were only a diversionary tactic, thus safeguarding the Allied landings and hastening the end of the war in Europe. Secret History Files is an exciting series from The National Archives that puts covert history in readers' hands. Dossiers previously classified as "Top Secret" are now available, with an explanatory introduction and background analysis by expert historians.
