That, for Brydon, was the deep sense of this last demonstration—­solemn, measured, directed, as he felt it to be.  He brought it to a close, he turned away; and now verily he knew how deeply he had been stirred.  He retraced his steps, taking up his candle, burnt, he observed, well-nigh to the socket, and marking again, lighten it as he would, the distinctness of his footfall; after which, in a moment, he knew himself at the other side of the house.  He did here what he had not yet done at these hours—­he opened half a casement, one of those in the front, and let in the air of the night; a thing he would have taken at any time previous for a sharp rupture of his spell.  His spell was broken now, and it didn’t matter—­broken by his concession and his surrender, which made it idle henceforth that he should ever come back.  The empty street—­its other life so marked even by great lamp-lit vacancy—­was within call, within touch; he stayed there as to be in it again, high above it though he was still perched; he watched as for some comforting common fact, some vulgar human note, the passage of a scavenger or a thief, some night-bird however base.  He would have blessed that sign of life; he would have welcomed positively the slow approach of his friend the policeman, whom he had hitherto only sought to avoid, and was not sure that if the patrol had come into sight he mightn’t have felt the impulse to get into relation with it, to hail it, on some pretext, from his fourth floor.

The pretext that wouldn’t have been too silly or too compromising, the explanation that would have saved his dignity and kept his name, in such a case, out of the papers, was not definite to him:  he was so occupied with the thought of recording his Discretion—­as an effect of the vow he had just uttered to his intimate adversary—­that the importance of this loomed large and something had overtaken all ironically his sense of proportion.  If there had been a ladder applied to the front of the house, even one of the vertiginous perpendiculars employed by painters and roofers and sometimes left standing overnight, he would have managed somehow, astride of the window-sill, to compass by outstretched leg and arm that mode of descent.  If there had been some such uncanny thing as he had found in his room at hotels, a workable fire-escape in the form of notched cable or a canvas shoot, he would have availed himself of it as a proof—­well, of his present delicacy.  He nursed that sentiment, as the question stood, a little in vain, and even—­at the end of he scarce knew, once more, how long—­found it, as by the action on his mind of the failure of response of the outer world, sinking back to vague anguish.  It seemed to him he had waited an age for some stir of the great grim hush; the life of the town was itself under a spell—­so unnaturally, up and down the whole prospect of known and rather ugly objects, the blankness and the silence lasted.  Had they ever, he asked himself, the hard-faced houses,
