"I will not leave you!" she cried. "The cave! It is our one chance!"
I saw her flash past us like a flying wisp of white and vanish in the cavern, and with a despairing cry, the youth launched a wild desperate stroke that nigh cleft my skull. As I staggered beneath the blow I had barely parried, he sprang away, leaped into the cavern after the girl and vanished in the gloom.
With a maddened yell that invoked all my grim Gaelic gods, I sprang recklessly after them, not reckoning if the Briton lurked beside the entrance to brain me as I rushed in. But a quick glance showed the chamber empty and a wisp of white disappearing through a dark doorway in the back wall.
I raced across the cavern and came to a sudden halt as an ax licked out of the gloom of the entrance and whistled perilously close to my black-maned head. I gave back suddenly. Now the advantage was with Vertorix, who stood in the narrow mouth of the corridor where I could hardly come at him without exposing myself to the devastating stroke of his ax.
I was near frothing with fury and the sight of a slim white form among the deep shadows behind the warrior drove me into a frenzy. I attacked savagely but warily, thrusting venomously at my foe, and drawing back from his strokes. I wished to draw him out into a wide lunge, avoid it and run him through before he could recover his balance. In the open I could have beat him down by sheer power and heavy blows, but here I could only use the point and that at a disadvantage; I always preferred the edge. But I was stubborn; if I could not come at him with a finishing stroke, neither could he or the girl escape me while I kept him hemmed in the tunnel.
It must have been the realization of this fact that prompted the girl's action, for she said something to Vertorix about looking for a way leading out, and though he cried out fiercely forbidding her to venture away into the darkness, she turned and ran swiftly down the tunnel to vanish in the dimness. My wrath rose appallingly and I nearly got my head split in my eagerness to bring down my foe before she found a means for their escape.
Then the cavern echoed with a terrible scream and Vertorix cried out like a man death-stricken, his face ashy in the gloom. He whirled, as if he had forgotten me and my sword, and raced down the tunnel like a madman, shrieking Tamera's name. From far away, as if from the bowels of the earth, I seemed to hear her answering cry, mingled with a strange sibilant clamor that electrified me with nameless but instinctive horror. Then silence fell, broken only by Vertorix's frenzied cries, receding farther and farther into the earth.
Recovering myself I sprang into the tunnel and raced after the Briton as recklessly as he had run after the girl. And to give me my due, red-handed reaver though I was, cutting down my rival from behind was less in my mind than discovering what dread thing had Tamera in its clutches.
As I ran along I noted absently that the sides of the tunnel were scrawled with monstrous pictures, and realized suddenly and creepily that this must be the dread Cavern of the Children of the Night, tales of which had crossed the narrow sea to resound horrifically in the ears of the Gaels. Terror of me must have ridden Tamera hard to have driven her into the cavern shunned by her people, where it was said, lurked the survivors of that grisly race which inhabited the land before the coming of the Picts and Britons, and which had fled before them into the unknown caverns of the hills.
Ahead of me the tunnel opened into a wide chamber, and I saw the white form of Vertorix glimmer momentarily in the semidarkness and vanish in what appeared to be the entrance of a corridor opposite the mouth of the tunnel I had just traversed. Instantly there sounded a short, fierce shout and the crash of a hard-driven blow, mixed with the hysterical screams of a girl and a medley of serpentlike hissing that made my hair bristle. And at that instant I shot out of the tunnel, running at full speed, and realized too late the floor of the cavern lay several feet below the level of the tunnel. My flying feet missed the tiny steps and I crashed terrifically on the solid stone floor.
Now as I stood in the semidarkness, rubbing my aching head, all this came back to me, and I stared fearsomely across the vast chamber at that black cryptic corridor into which Tamera and her lover had disappeared, and over which silence lay like a pall. Gripping my sword, I warily crossed the great still cavern and peered into the corridor. Only a denser darkness met my eyes. I entered, striving to pierce the gloom, and as my foot slipped on a wide wet smear on the stone floor, the raw acrid scent of fresh-spilled blood met my nostrils. Someone or something had died there, either the young Briton or his unknown attacker.
I stood there uncertainly, all the supernatural fears that are the heritage of the Gael rising in my primitive soul. I could turn and stride out of these accursed mazes, into the clear sunlight and down to the clean blue sea where my comrades, no doubt, impatiently awaited me after the routing of the Britons. Why should I risk my life among these grisly rat dens? I was eaten with curiosity to know what manner of beings haunted the cavern, and who were called the Children of the Night by the Britons, but in it was my love for the yellow-haired girl which drove me down that dark tunnel— and love her I did, in my way, and would have been kind to her, had I carried her away to my island haunt.
I walked softly along the corridor, blade ready. What sort of creatures the Children of the Night were, I had no idea, but the tales of the Britons had lent them a distinctly inhuman nature.
The darkness closed around me as I advanced, until I was moving in utter blackness. My groping left hand encountered a strangely carven doorway, and at that instant something hissed like a viper beside me and slashed fiercely at my thigh. I struck back savagely and felt my blind stroke crunch home, and something fell at my feet and died. What thing I had slain in the dark I could not know, but it must have been at least partly human because the shallow gash in my thigh had been made with a blade of some sort, and not by fangs or talons. And I sweated with horror, for the gods know, the hissing voice of the Thing had resembled no human tongue I had ever heard.
And now in the darkness ahead of me I heard the sound repeated, mingled with horrible slitherings, as if numbers of reptilian creatures were approaching. I stepped quickly into the entrance my groping hand had discovered and came near repeating my headlong fall, for instead of letting into another level corridor, the entrance gave onto a flight of dwarfish steps on which I floundered wildly.
Recovering my balance I went on cautiously, groping along the sides of the shaft for support. I seemed to be descending into the very bowels of the earth, but I dared not turn back. Suddenly, far below me, I glimpsed a faint eerie light. I went on, perforce, and came to a spot where the shaft opened into another great vaulted chamber; and I shrank back, aghast.
In the center of the chamber stood a grim, black altar; it had been rubbed all over with a sort of phosphorous, so that it glowed dully, lending a semi-illumination to the shadowy cavern. Towering behind it on a pedestal of human skulls, lay a cryptic black object, carven with mysterious hieroglyphics. The Black Stone! The ancient, ancient Stone before which, the Britons said, the Children of the Night bowed in gruesome worship, and whose origin was lost in the black mists of a hideously distant past. Once, legend said, it had stood in that grim circle of monoliths called Stonehenge, before its votaries had been driven like chaff before the bows of the Picts.
But I gave it but a passing, shuddering glance. Two figures lay, bound with rawhide thongs, on the glowing black altar. One was Tamera; the other was Vertorix, bloodstained and disheveled. His bronze ax, crusted with clotted blood, lay near the altar. And before the glowing stone squatted Horror.
Though I had never seen one of those ghoulish aborigines, I knew this thing for what it was, and shuddered. It was a man of a sort, but so low in the stage of life that its distorted humanness was more horrible than its bestiality.
