“What [Kim] Philby does not seem to have realized was that Allen [Dulles] was almost as good an actor as he was, that he too had built up a persona over the years, and that all was not as sunny, lighthearted, and easygoing inside as it seemed on the surface. There were, too, senior members of his staff to whom he listened carefully, even when it was only small talk between them, and the one to whom he paid most heed was his director of Counterintelligence, James Jesus Angleton. Angleton was Allen’s antithesis, a cold fish, unsociable, introverted, relaxed only with Englishmen and his friends in the Israeli intelligence services, with whom he had close connections. But underneath his distant manner and snobbish air, he had an acute skill for sensing the phoney in men, and an unerring eye for the chinks in their armor. And at a late night session with Allen, he had once talked about Kim Philby. He described how, one day in London shortly after the war, they were on their way to a ceremony at Buckingham Palace where King George VI was to present an award to Philby for his wartime services. Perhaps Philby was disenchanted that it was only an OBE when, as many of his friends thought, he had really earned himself a knighthood. At any rate, he stopped just before they entered the yard of the Palace, and, turning to Angleton, said: ‘You know, what this country could do with is a good dose of socialism.’
To Angelton, the remark rang bells.
‘From that moment on, I’ve been wary of the fellow,’ he told Allen. ‘You know, he sounded like a Commie. I have a feeling in my bones about him.'”
