Before any of us could recover our faculties, Octave flung aside the metal bar and began to fumble for something in the wall. It must have been a hidden spring; though how he could have known its location or existence is beyond all legitimate conjecture. With a dull, hideous grating, the uncovered door swung inward, thick and ponderous as a mausolean slab, leaving an aperture from which the nether midnight seemed to well like a flood of aeon-buried foulness. Somehow, at that instant, our electric torches appeared to flicker and grow dim; and we all breathed a suffocating fetor, like a draft from inner worlds of immemorial putrescence.
Octave had turned toward us now, and he stood in an idle posture before the open door, like one who has finished some ordained task. I was the first of our party to throw off the paralyzing spell; and pulling out a clasp-knife—the only semblance of a weapon which I carried—I ran over to him. He moved back, but not quickly enough to evade me, when I stabbed with the four-inch blade at the black, turgescent mass that enveloped his whole upper head and hung down upon his eyes.
What the thing was, I should prefer not to imagine—if it were possible to imagine. It was formless as a great slug, with neither head nor tail nor apparent organs—an unclean, puffy, leathery thing, covered with that fine, mould-like fur of which I have spoken. The knife tore into it as if through rotten parchment, making a long gash, and the horror appeared to collapse like a broken bladder. Out of it there gushed a sickening torrent of human blood, mingled with dark, filiated masses that may have been half-dissolved hair, and floating gelatinous lumps like molten bone, and shreds of a curdy white substance. At the same time, Octave began to stagger, and went down at full length on the floor. Disturbed by his fall, the mummy-dust arose about him in a curling cloud, beneath which he lay mortally still.
Conquering my revulsion, and choking with the dust, I bent over him and tore the flaccid, oozing horror from his head. It came with unexpected ease, as if I had removed a limp rag: but I wish to God that I had let it remain. Beneath, there was no longer a human cranium, for all had been eaten away, even to the eyebrows, and the half-devoured brain was laid bare as I lifted the cowl-like object. I dropped the unnamable thing from fingers that had grown suddenly nerveless, and it turned over as it fell, revealing on the nether side many rows of pinkish suckers, arranged in circles about a pallid disk that was covered with nerve-like filaments, suggesting a sort of plexus.
My companions had pressed forward behind me; but, for an appreciable interval, no one spoke.
“How long do you suppose he has been dead?” It was Halgren who whispered the awful question, which we had all been asking ourselves. Apparently no one felt able or willing to answer it; and we could only stare in horrible, timeless fascination at Octave.
At length I made an effort to avert my gaze; and turning at random, I saw the remnants of the shackled mummy, and noted for the first time, with mechanical, unreal horror, the half-eaten condition of the withered head. From this, my gaze was diverted to the newly opened door at one side, without perceiving for a moment what had drawn my attention. Then, startled, I beheld beneath my torch, far down beyond the door, as if in some nether pit, a seething, multitudinous, worm-like movement of crawling shadows. They seemed to boil up in the darkness; and then, over the broad threshold of the vault, there poured the verminous vanguard of a countless army: things that were kindred to the monstrous, diabolic leech I had torn from Octave’s eaten head. Some were thin and flat, like writhing, doubling disks of cloth or leather, and others were more or less poddy, and crawled with glutted slowness. What they had found to feed on in the sealed, eternal midnight I do not know; and I pray that I never shall know.
I sprang back and away from them, electrified with terror, sick with loathing, and the black army inched itself unendingly with nightmare swiftness from the unsealed abyss, like the nauseous vomit of horror-sated hells. As it poured toward us, burying Octave’s body from sight in a writhing wave, I saw a stir of life from the seemingly dead thing I had cast aside, and saw the loathly struggle which it made to right itself and join the others.
But neither I nor my companions could endure to look longer. We turned and ran between the mighty rows of urns, with the slithering mass of demon leeches close upon us, and scattered in blind panic when we came to the first division of the vaults. Heedless of each other or of anything but the urgency of flight, we plunged into the ramifying passages at random. Behind me, I heard someone stumble and go down, with a curse that mounted to an insane shrieking; but I knew that if I halted and went back, it would be only to invite the same baleful doom that had overtaken the hindmost of our party.
Still clutching the electric torch and my open clasp-knife, I ran along a minor passage which, I seemed to remember, would conduct with more or less directness upon the large outer vault with the painted floor. Here I found myself alone. The others had kept to the main catacombs; and I heard far off a muffled babel of mad cries, as if several of them had been seized by their pursuers.
It seemed that I must have been mistaken about the direction of the passage; for it turned and twisted in an unfamiliar manner, with many intersections, and I soon found that I was lost in the black labyrinth, where the dust had lain unstirred by living feet for inestimable generations. The cinerary warren had grown still once more; and I heard my own frenzied panting, loud and stertorous as that of a Titan in the dead silence.
Suddenly, as I went on, my torch disclosed a human figure coming toward me in the gloom. Before I could master my startlement, the figure had passed me with long, machine-like strides, as if returning to the inner vaults. I think it was Harper, since the height and build were about right for him; but I am not altogether sure, for the eyes and upper head were muffled by a dark, inflated cowl, and the pale lips locked as if in a silence of tetanic torture—or death. Whoever he was, he had dropped his torch; and he was running blindfold, in utter darkness, beneath the impulsion of that unearthly vampirism, to seek the very fountain-head of the unloosed horror. I knew that he was beyond human help; and I did not even dream of trying to stop him.
Trembling violently, I resumed my flight, and was passed by two more of our party, stalking by with mechanical swiftness and sureness, and cowled with those Satanic leeches. The others must have returned by way of the main passages; for I did not meet them; and was never to see them again.
The remainder of my flight is a blur of pandemonian terror. Once more, after thinking that I was near the outer cavern, I found myself astray, and fled through a ranged eternity of monstrous urns, in vaults that must have extended for an unknown distance beyond our explorations. It seemed that I had gone on for years; and my lungs were choking with the aeon-dead air, and my legs were ready to crumble beneath me, when I saw far off a tiny point of blessed daylight. I ran toward it, with all the terrors of the alien darkness crowding behind me, and accursed shadows flittering before, and saw that the vault ended in a low, ruinous entrance, littered by rubble on which there fell an arc of thin sunshine.
It was another entrance than the one by which we had penetrated this lethal underworld. I was within a dozen feet of the opening when, without sound or other intimation, something dropped upon my head from the roof above, blinding me instantly and closing upon me like a tautened net. My brow and scalp, at the same time, were shot through with a million needle-like pangs—a manifold, ever-growing agony that seemed to pierce the very bone and converge from all sides upon my inmost brain.
The terror and suffering of that moment were worse than aught which the hells of earthly madness or delirium could ever contain. I felt the foul, vampiric clutch of an atrocious death—and of more than death.
