" Angleton is not to be trifled with. I don’t know anyone else currently alive and in the organization who could get away with misappropriating the name of the CIA’s legendary chief of counter-espionage as a nom de guerre. I don’t know anyone else in the organization whose face is visible in circa-1942 photographs of the Laundry’s line-up, either, barely changed across all those years. "
