Was the FBI agent who busted the Miami gang named "O'Brien"?

'Does the Brotherhood exist?'

'That, Winston, you will never know. If we choose to set you free when we have finished with you, and if you live to be ninety years old, still you will never learn whether the answer to that question is Yes or No. As long as you live it will be an unsolved riddle in your mind.'

The beatings grew less frequent, and became mainly a threat, a horror to which he could be sent back at any moment when his answers were unsatisfactory. His questioners now were not ruffians in black uniforms but Party intellectuals, little rotund men with quick movements and flashing spectacles, who worked on him in relays over periods which lasted -- he thought, he could not be sure -- ten or twelve hours at a stretch. These other questioners saw to it that he was in constant slight pain, but it was not chiefly pain that they relied on. They slapped his face, wrung his ears, pulled his hair, made him stand on one leg, refused him leave to urinate, shone glaring lights in his face until his eyes ran with water; but the aim of this was simply to humiliate him and destroy his power of arguing and reasoning. Their real weapon was the merciless questioning that went on and on, hour after hour, tripping him up, laying traps for him, twisting everything that he said, convicting him at every step of lies and self-contradiction until he began weeping as much from shame as from nervous fatigue. Sometimes he would weep half a dozen times in a single session. Most of the time they screamed abuse at him and threatened at every hesitation to deliver him over to the guards again; but sometimes they would suddenly change their tune, call him comrade, appeal to him in the name of Ingsoc and Big Brother, and ask him sorrowfully whether even now he had not enough loyalty to the Party left to make him wish to undo the evil he had done. When his nerves were in rags after hours of questioning, even this appeal could reduce him to snivelling tears. In the end the nagging voices broke him down more completely than the boots and fists of the guards. He became simply a mouth that uttered, a hand that signed, whatever was demanded of him. His sole concern was to find out what they wanted him to confess, and then confess it quickly, before the bullying started anew. He confessed to the assassination of eminent Party members, the distribution of seditious pamphlets, embezzlement of public funds, sale of military secrets, sabotage of every kind. He confessed that he had been a spy in the pay of the Eastasian government as far back as 1968. He confessed that he was a religious believer, an admirer of capitalism, and a sexual pervert. He confessed that he had murdered his wife, although he knew, and his questioners must have known, that his wife was still alive. He confessed that for years he had been in personal touch with Goldstein and had been a member of an underground organization which had included almost every human being he had ever known. It was easier to confess everything and implicate everybody. Besides, in a sense it was all true. It was true that he had been the enemy of the Party, and in the eyes of the Party there was no distinction between the thought and the deed.
