Agent Tate

This is the career of the longest serving double agent in the Double Cross system, Harry Williamson. Working under the cover name TATE, he went on to send more than a thousand messages during the war. Harry took part in D-Day, provided the Nazis with misinformation, and misled the German Navy with faulty intelligence over U-boat minefields. After the war he was almost completely anonymous until his name was revealed in the 1990s.
