"That was the first time I ever saw my brother. But I knew him. And I knew I would disobey the Party. Perhaps it was the tie of blood between us, but I doubt it; we were only half-tied anyway, and brothers will betray a brother. Indeed, as a policeman I would say get hold of a man's brother and you're half-way home. Nor was it admiration for a better man than me. I did admire him; but I didn't think he was a better man. Besides, I've executed better men than me with a small pistol."
