Anthony Blunt was tall, charming, arrogant, somewhat cold, and a dedicated Communist. He was the grandson of an Anglican bishop, and the son of an Anglican vicar. He was a discrete homosexual, and for a short time he and Burgess were lovers. During the war, Blunt served in MI5 --- the British equivalent of the FBI. After the war, he became director of the Courtauld Institute of Art, since he was a specialist in the history of art. Eventually, he became the Royal Family's art advisor, and was knighted in 1956. He was stripped of his knighthood in 1979, shortly after Margaret Thatcher publicly declared him to have been a Russian spy. He died in 1983.
