The conflict continued without diminishing. He struggled once more to his feet, with Nicholas, and they exchanged battering blows, dealt necessarily at random. Sometimes his arm swept violently through mere space, at others his fist landed with a satisfying shock on the body of his antagonist. The dark was occasionally crossed by flashes before Woolfolk's smitten eyes, but no actual light pierced the profound night of the upper hall. At times their struggle grew audible, smacking blows fell sharply; but there was no other sound except that of the wind tearing at the sashes, thundering dully in the loose tin roof, rocking the dwelling. They fell again, and equally their efforts slackened, their grips became more feeble. Finally, as if by common consent, they rolled apart. A leaden tide of apathy crept over Woolfolk's battered body, folded his aching brain. He listened in a sort of indifferent attention to the tempestuous breathing of Iscah Nicholas. John Woolfolk wondered dully where Millie was. There had been no sign of her since he had fallen down the step and she had cried out. Perhaps she was dead from fright. He considered this possibility in a hazy, detached manner. She would be better dead--if he failed. He heard, with little interest, a stirring on the floor beside him, and thought with an overwhelming weariness and distaste that the strife was to commence once more. But, curiously, Nicholas moved away from him. Woolfolk was glad; and then he was puzzled for a moment by the sliding of hands over an invisible wall. He slowly realized that the other was groping for the knife he had buried in the plaster. John Woolfolk considered a similar search for the pistol he had dropped; he might even light a match. It was a rather wonderful weapon and would spray lead like a hose of water. He would like exceedingly well to have it in his hand with Nicholas before him. Then in a sudden mental illumination he realized the extreme peril of the moment; and, lurching to his feet, he again threw himself on the other. The struggle went on, apparently to infinity; it was less vigorous now; the blows, for the most part, were impotent. Iscah Nicholas never said a word; and fantastic thoughts wheeled through Woolfolk's brain. He lost all sense of the identity of his opponent and became convinced that he was combating an impersonal hulk--the thing that gasped and smeared his face, that strove to end him, was the embodied and evil spirit of the place, a place that even Halvard had seen was damnably wrong. He questioned if such a force could be killed, if a being materialized from the outer dark could be stopped by a pistol of even the latest, most ingenious mechanism.
