That was the essence of his vision - which was all rank folly, if one would, while he was out of the house and otherwise occupied, but which took on the last verisimilitude as soon as he was placed and posted. He knew what he meant and what he wanted; it was as clear as the figure on a cheque presented in demand for cash. His ALTER EGO "walked" - that was the note of his image of him, while his image of his motive for his own odd pastime was the desire to waylay him and meet him. He roamed, slowly, warily, but all restlessly, he himself did - Mrs. Muldoon had been right, absolutely, with her figure of their "craping"; and the presence he watched for would roam restlessly too. But it would be as cautious and as shifty; the conviction of its probable, in fact its already quite sensible, quite audible evasion of pursuit grew for him from night to night, laying on him finally a rigour to which nothing in his life had been comparable. It had been the theory of many superficially-judging persons, he knew, that he was wasting that life in a surrender to sensations, but he had tasted of no pleasure so fine as his actual tension, had been introduced to no sport that demanded at once the patience and the nerve of this stalking of a creature more subtle, yet at bay perhaps more formidable, than any beast of the forest. The terms, the comparisons, the very practices of the chase positively came again into play; there were even moments when passages of his occasional experience as a sportsman, stirred memories, from his younger time, of moor and mountain and desert, revived for him - and to the increase of his keenness - by the tremendous force of analogy. He found himself at moments - once he had placed his single light on some mantel-shelf or in some recess - stepping back into shelter or shade, effacing himself behind a door or in an embrasure, as he had sought of old the vantage of rock and tree; he found himself holding his breath and living in the joy of the instant, the supreme suspense created by big game alone.
He wasn't afraid (though putting himself the question as he believed gentlemen on Bengal tiger-shoots or in close quarters with the great bear of the Rockies had been known to confess to having put it); and this indeed - since here at least he might be frank! -because of the impression, so intimate and so strange, that he himself produced as yet a dread, produced certainly a strain, beyond the liveliest he was likely to feel. They fell for him into categories, they fairly became familiar, the signs, for his own perception, of the alarm his presence and his vigilance created;though leaving him always to remark, portentously, on his probably having formed a relation, his probably enjoying a consciousness, unique in the experience of man. People enough, first and last, had been in terror of apparitions, but who had ever before so turned the tables and become himself, in the apparitional world, an incalculable terror? He might have found this sublime had he quite dared to think of it; but he didn't too much insist, truly, on that side of his privilege. With habit and repetition he gained to an extraordinary degree the power to penetrate the dusk of distances and the darkness of corners, to resolve back into their innocence the treacheries of uncertain light, the evil-looking forms taken in the gloom by mere shadows, by accidents of the air, by shifting effects of perspective; putting down his dim luminary he could still wander on without it, pass into other rooms and, only knowing it was there behind him in case of need, see his way about, visually project for his purpose a comparative clearness. It made him feel, this acquired faculty, like some monstrous stealthy cat;he wondered if he would have glared at these moments with large shining yellow eyes, and what it mightn't verily be, for the poor hard-pressed ALTER EGO, to be confronted with such a type.
He liked however the open shutters; he opened everywhere those Mrs.
Muldoon had closed, closing them as carefully afterwards, so that she shouldn't notice: he liked - oh this he did like, and above all in the upper rooms! - the sense of the hard silver of the autumn stars through the window-panes, and scarcely less the flare of the street-lamps below, the white electric lustre which it would have taken curtains to keep out. This was human actual social;this was of the world he had lived in, and he was more at his ease certainly for the countenance, coldly general and impersonal, that all the while and in spite of his detachment it seemed to give him.
He had support of course mostly in the rooms at the wide front and the prolonged side; it failed him considerably in the central shades and the parts at the back. But if he sometimes, on his rounds, was glad of his optical reach, so none the less often the rear of the house affected him as the very jungle of his prey. The place was there more subdivided; a large "extension" in particular, where small rooms for servants had been multiplied, abounded in nooks and corners, in closets and passages, in the ramifications especially of an ample back staircase over which he leaned, many a time, to look far down - not deterred from his gravity even while aware that he might, for a spectator, have figured some solemn simpleton playing at hide-and-seek. Outside in fact he might himself make that ironic RAPPROCHEMENT; but within the walls, and in spite of the clear windows, his consistency was proof against the cynical light of New York.
