Cleaving closely as a tightened cloth, the thing enfolded Octave’s hair and brow and eyes, and he shrieked wildly, with incoherent pleas for help, and tore with frantic fingers at the cowl, but failed to loosen it. Then his cries began to mount in a mad crescendo of agony, as if beneath some instrument of infernal torture; and he danced and capered blindly about the vault, eluding us with strange celerity as we all sprang forward in an effort to reach him and release him from his weird encumbrance. The whole happening was mysterious as a nightmare; but the thing that had fallen on his head was plainly some unclassified form of Martian life, which, contrary to all the known laws of science, had survived in those primordial catacombs. We must rescue him from those clutches if we could.
We tried to close in on the frenzied figure of our chief–which, in the far from roomy space between the last urns and the wall, should have been an easy matter. But, darting away, in a manner doubly incomprehensible because of his blindfolded condition, he circled about us and ran past, to disappear among the urns toward the outer labyrinth of intersecting catacombs.
“My God! What has happened to him?” cried Harper. “The man acts as if he were possessed.”
There was obviously no time for a discussion of the enigma, and we all followed Octave as speedily as our astonishment would permit. We had lost sight of him in the darkness; and when we came to the first division of the vaults, we were doubtful as to which passage he had taken, till we heard a shrill scream, several times repeated, in a catacomb on the extreme left. There was a weird, unearthly quality in those screams, which may have been due to the long-stagnant air or the peculiar acoustics of the ramifying caverns. But somehow I could not imagine them as issuing from human lips–at least not from those of a living man. They seemed to contain a soulless, mechanical agony, as if they had been wrung from a devil-driven corpse.
Thrusting our torches before us into the lurching, fleeing shadows, we raced along between rows of mighty urns. The screaming had died away in sepulchral silence; but far off we heard the light and muffled thud of running feet. We followed in headlong pursuit; but, gasping painfully in the vitiated, miasmal air, we were soon compelled to slacken our pace without coming in sight of Octave. Very faintly, and further away than ever, like the tomb-swallowed steps of a phantom, we heard his vanishing footfalls. Then they ceased; and we heard nothing, except our own convulsive breathing, and the blood that throbbed in our temple-veins like steadily beaten drums of alarm.
We went on, dividing our party into three contingents when we came to a triple branching of the caverns. Harper and Halgren and I took the middle passage, and after we had gone on for an endless interval without finding any trace of Octave, and had threaded our way through recesses piled to the roof with colossal urns that must have held the ashes of a hundred generations, we came out in the huge chamber with the geometric floor-designs. Here, very shortly, we were joined by the other, who had likewise failed to locate our missing leader.
It would be useless to detail our renewed and hour-long search of the myriad vaults, many of which we had not hitherto explored. All were empty, as far as any sign of life was concerned. I remember passing once more through the vault in which I had seen the dark, rounded patch on the ceiling, and noting with a shudder that the patch was gone. It was a miracle that we did not lose ourselves in that underworld maze; but at last we came back again to the final catacomb, in which we had found the shackled mummy.
We heard a measured and recurrent clangor as we neared the place–a most alarming and mystifying sound under the circumstances. It was like the hammering of ghouls on some forgotten mausoleum. When we drew nearer, the beams of our torches revealed a sight that was no less unexplainable than unexpected. A human figure, with its back toward us and the head concealed by a swollen black object that had the size and form of a sofa cushion, was standing near the remains of the mummy and was striking at the wall with a pointed metal bar. How long Octave had been there, and where he had found the bar, we could not know. But the blank wall had crumbled away beneath his furious blows, leaving on the floor a pile of cement-like fragments; and a small, narrow door, of the same ambiguous material as the cinerary urns and the fumigating-pan, had been laid bare.
Amazed, uncertain, inexpressibly bewildered, we were all incapable of action or volition at that moment. The whole business was too fantastic and too horrifying, and it was plain that Octave had been overcome by some sort of madness. I, for one, felt the violent upsurge of sudden nausea when I had identified the loathsomely bloated thing that clung to Octave’s head and drooped in obscene tumescence on his neck. I did not dare to surmise the causation of its bloating.
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 flickered and grew dim; and we all breathed a suffocating fetor, like a draught 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 gutted 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.
