An Albanian from Kosovo, Bazna was hired by the British Ambassador to Turkey during World War II as his valet. He was, in actuality, a spy working for the German intelligence service, and photographed and copied many top-secret documents from the ambassador's safe and that the ambassador had, against policy, left lying around his office or at his home without securing them. Although the information he passed along could have severely damaged the Allied war effort, the leadership of the German intelligence services didn't entirely trust him and thought he might be a double agent, and thereby didn't act on much of the information he gave them (including the day and time that Operation Overlord--the invasion of Europe--was scheduled to begin). He passed along information for almost a year, and in 1944 he started hearing rumors about there being a spy in the British Embassy and that British intelligence was pulling out all the stops to find out who it was. He left the Ambassador's employ in 1944, and his identity wasn't discovered until after the war ended.
