To be blunt….
I was worried about Blunt.
I remembered something, but I didn't know what it was.
Now I remember.
Anthony Blunt, a gay noble British spy for the Soviets.
Nobody could believe at that time that a man so highly respected could betray his own country to the communists.
Sir Anthony Blunt,
an above-reproach aristocrat and renowned art expert. In 1951, Blunt sells out his country by helping turncoat British spy Donald MacLean escape to Moscow. Blunt's stake in all this intrigue is personal: he is the former gay lover of MacLean's partner in espionage, the notorious Guy Burgess. The revelation of Blunt's role as the "fourth man" in Britain's most famous modern spy scandal is not made public until 1979.
The story was also made into a movie.
