Soviet spy operating in Britain throughout World War II and part of the cold war. Blunt was a member of the Cambridge Four, a group of upper-crust traitors who did untold damage to British Intelligence services.

It is believed that Blunt recruited all three of his compatriots, although he denied it.

Despite striking a deal for anonymity in exchange for his confession, Blunt was eventually exposed by Margaret Thatcher and stripped of his knighthood. He died in disgrace (but still fantastically wealthy) in 1983.
