That was all, and he was already uncertain whether it had happened. Such incidents never had any sequel. All that they did was to keep alive in him the belief, or hope, that others besides himself were the enemies of the Party. Perhaps the rumours of vast underground conspiracies were true after all – perhaps the Brotherhood really existed! It was impossible, in spite of the endless arrests and confessions and executions, to be sure that the Brotherhood was not simply a myth. Some days he believed in it, some days not. There was no evidence, only fleeting glimpses that might mean anything or nothing: snatches of over-heard conversation, faint scribbles on lavatory walls – once, even, when two strangers met, a small movement of the hands which had looked as though it might be a signal of recognition. It was all guesswork: very likely he had imagined everything. He had gone back to his cubicle without looking at O’Brien again. The idea of following up their momentary contact hardly crossed his mind. It would have been inconceivably dangerous even if he had known how to set about doing it. For a second, two seconds, they had exchanged an equivocal glance, and that was the end of the story. But even that was a memorable event in the locked loneliness in which one had to live.
