This knowledge flashed through his mind with the rapidity of a kinetoscope plate, and a moment later was obliterated by still another hurrying impression. For, through the deserted house rang two short and terrified screams, high-pitched and piercing. They were a woman's screams, and he knew they could come from no one but Frank.
He turned and hurled himself down the stairway, without even waiting to recover the revolver that had fallen a minute before from his startled fingers. He was conscious only of flinging the weight of his sliding body on the flume-like surface of the smooth balustrade, with his feet clattering on the polished steps as he went. He turned and dashed on to the head of the next stairway, and in the same manner flung himself to the floor beneath, and then to the next, and the next, until he was in the gloom of the basement itself.
Breathless and panting, he groped his way through the darkness, to where a glimmer of light came from what he hurriedly took to be the engine-room.
There, as he darted through the narrow doorway, into the circle of dim light from the one tinted globe in the lowered elevator cage, a strange sight met his eyes. It shocked and flung him into a second or two of blank indecision, of volitionless and thoughtless inactivity. For one moment of ominous calm it smote and held him there, before the sudden blind, cyclonic rush of brain and body which the vision gave rise to.
For at the door of the open cage MacNutt and Frank fought and struggled and panted together. The man was inside, on the bottom of the cage, the woman was outside it. Her huddled but still resisting body was locked and jammed halfway across the narrow door. One of her opponent's great, ape-like strangling arms was about her neck. But the fingers at the end of it were caught between her strong white carnivorous teeth; and they became stained with blood as, in her frenzy, she fought and bit and struggled, with the blind fury of some final despair. Her revolver she had been unable to use; it lay out of her reach, behind them on the floor of the cage.
MacNutt, as he strained and tore at her resisting body, was fighting and edging his way with her back into the cage, to where that waiting revolver lay. He himself was already well within the narrow opening, sprawled out red and disheveled and Titanesque on the cage floor. But she was resisting him, inch by inch, fighting desperately, like a cornered cat, for her very life, yet knowing there could be only one end to that uneven conflict.
Durkin, after one comprehending glance, followed his first animal impulse of offense, and descended on MacNutt, beating at the prone, bull-like head, with its claret-colored bald spot, across which ran one livid scratch. He pounded on the clustered fingers of the gorilla-like hand, crushing and bruising them against the gilded iron grill-work, through which was interwoven the Penfield triple crescent.
The clutching arms relaxed, but only for a moment. In that moment, however, Durkin had stooped and with the one hand that remained with him to use, struggled to tear Frank away from the deadly clutch. This he would surely have done had not MacNutt seen his chance, and with his free hand suddenly caught at the wounded wrist that hung stained and limp at his enemy's side. That sudden, savage torture of the lacerated flesh was more than the weak and exhausted body of Durkin could endure. He emitted one little involuntary cry; then every protesting nerve and sinew capitulated, a white light seemed to flash and burn at the base of his very brain, and then go out. He fell fainting on the hard maple floor.
For a moment or two, like a defeated prize-fighter, he panted and struggled, ludicrously yet pathetically, to rise to his feet, but the effort was futile.
It was as he found himself ebbing down through some soft and feathery emptiness that he seemed to hear a pitiful and imploring voice call thinly out, "Mack!" Still fainter he seemed to hear it, "Mack! Come up! I'm dying!" He remembered, lazily, that it sounded like the distant voice of Keenan—but where was Keenan?
