But there, momentarily, he paused in doubt and trembling. In that exposed and comfortless perch, the lifeless street on one hand, the black mystery of the neglected park on the other, he was seized and shaken by a sudden revulsion of feeling like a sickness of his very soul. Physical fear had nothing to do with this, for he was quite alone and unobserved; had it been otherwise faculties trained through a lifetime to such work as this and now keyed to concert pitch would not have failed to give warning of whatever danger his grosser senses might have overlooked.

Notwithstanding, he was afraid as though Fear's very self had laid hold of his soul by the heels and would not let it go until its vision of itself was absolute. He was afraid with a great fear such as he had never dreamed to know; who knew well the wincing of the flesh from risk of pain, the shuddering of the spirit in the shadow of death, and horror such as had gripped him that morning in poor Roddy's bed-chamber.

But none of these had in any way taught him the measure of such fear as now possessed him, so absolute that he quaked like a naked soul in the inexorable presence of the Eternal.

He was afraid of himself, in panic terror of that ego which tenanted the shell of functioning, sensitive stuff called Michael Lanyard: he was afraid of the strange, silent, incomprehensible Self lurking occult in him, that masked mysterious Self which in its inscrutable whim could make him fine or make him base, that Self impalpable and elusive as any shadow yet invincibly strong, his master and his fate, in one the grave of Yesterday, the cup of Today, the womb of Tomorrow….

He looked up at the tired, dull faces of those old dwellings that loomed across the way with blind and lightless windows, sleeping without suspicion that he had stolen in among them—the grim and deadly thing that walked by night, the Lone Wolf, creature of pillage and rapine, scourged slave of that Self which knew no law….

Then slowly that obsession lifted like the passing of a nightmare; and with a start, a little shiver and a sigh, Lanyard roused and went on to do the bidding of his Self for its unfathomable ends….

Dropping silently to the soft, damp turf, he made himself one with the shadows of the park, as mute, intangible and fugitive as they, until presently coming out beneath the stars, on an open lawn running up to the library wing of the hôtel, he approached a shallow stone balcony which jutted forth eight feet above the lawn—an elevation so inconsiderable that, with one bound grasping its stone balustrade, the adventurer was upon it in a brace of seconds.

Nor did the long French windows that opened on the balcony offer him any real hindrance: a penknife quickly removed the dried putty round one small, lozenge-shaped pane, then pried out the pane itself; a hand through this space readily found and turned the latch; a cautious pressure opened the two wings far enough to admit his body; and—he stood inside the library.

He had made no sound; and thanks to thorough familiarity with the ground, he needed no light. The screen of cinnabar afforded all the protection he required; and because he meant to accomplish his purpose and be out of the house with the utmost expedition, he didn't trouble to explore beyond a swift, casual review of the adjoining salons.

The clock was chiming the three-quarters as he knelt behind the screen and grasped the combination-knob.
