He took it full in the face that something had happened between -that he couldn't have noticed before (by which he meant on his original tour of all the rooms that evening) that such a barrier had exceptionally presented itself. He had indeed since that moment undergone an agitation so extraordinary that it might have muddled for him any earlier view; and he tried to convince himself that he might perhaps then have gone into the room and, inadvertently, automatically, on coming out, have drawn the door after him. The difficulty was that this exactly was what he never did; it was against his whole policy, as he might have said, the essence of which was to keep vistas clear. He had them from the first, as he was well aware, quite on the brain: the strange apparition, at the far end of one of them, of his baffled "prey"(which had become by so sharp an irony so little the term now to apply!) was the form of success his imagination had most cherished, projecting into it always a refinement of beauty. He had known fifty times the start of perception that had afterwards dropped;had fifty times gasped to himself. "There!" under some fond brief hallucination. The house, as the case stood, admirably lent itself; he might wonder at the taste, the native architecture of the particular time, which could rejoice so in the multiplication of doors - the opposite extreme to the modern, the actual almost complete proscription of them; but it had fairly contributed to provoke this obsession of the presence encountered telescopically, as he might say, focused and studied in diminishing perspective and as by a rest for the elbow.
It was with these considerations that his present attention was charged - they perfectly availed to make what he saw portentous.
He COULDN'T, by any lapse, have blocked that aperture; and if he hadn't, if it was unthinkable, why what else was clear but that there had been another agent? Another agent? - he had been catching, as he felt, a moment back, the very breath of him; but when had he been so close as in this simple, this logical, this completely personal act? It was so logical, that is, that one might have TAKEN it for personal; yet for what did Brydon take it, he asked himself, while, softly panting, he felt his eyes almost leave their sockets. Ah this time at last they WERE, the two, the opposed projections of him, in presence; and this time, as much as one would, the question of danger loomed. With it rose, as not before, the question of courage - for what he knew the blank face of the door to say to him was "Show us how much you have!" It stared, it glared back at him with that challenge; it put to him the two alternatives: should he just push it open or not? Oh to have this consciousness was to THINK - and to think, Brydon knew, as he stood there, was, with the lapsing moments, not to have acted! Not to have acted - that was the misery and the pang - was even still not to act; was in fact ALL to feel the thing in another, in a new and terrible way. How long did he pause and how long did he debate? There was presently nothing to measure it; for his vibration had already changed - as just by the effect of its intensity. Shut up there, at bay, defiant, and with the prodigy of the thing palpably proveably DONE, thus giving notice like some stark signboard - under that accession of accent the situation itself had turned; and Brydon at last remarkably made up his mind on what it had turned to.
