The voice rose to a shriek, foam spattered from the livid writhing lips, and Richard Ballville heaved himself almost upright, then toppled limply back. The iron will that had animated the broken body had snapped at last, as a taut wire snaps.
McGrath looked down at the still form, his brain a maelstrom of seething emotions, then wheeled, glaring, every nerve atingle, his pistol springing into his hand.
3. The Black Priest
A man stood in the doorway that opened upon the great outer hall — a tall man in a strange alien garb. He wore a turban and a silk coat belted with a gay-hued girdle. Turkish slippers were on his feet. His skin was not much darker than McGrath’s, his features distinctly oriental in spite of the heavy glasses he wore.
“Who the devil are you?” demanded McGrath, covering him.
“Ali ibn Suleyman, effendi,” answered the other in faultless Arabic. “I came to this place of devils at the urging of my brother, Ahmed ibn Suleyman, whose soul may the Prophet ease. In New Orleans the letter came to me. I hastened here. And lo, stealing through the woods, I saw black men dragging my brother’s corpse to the river. I came on, seeking his master.”
McGrath mutely indicated the dead man. The Arab bowed his head in stately reverence.
“My brother loved him,” he said. “I would have vengeance for my brother and my brother’s master. Effendi, let me go with you.”
“All right.” McGrath was afire with impatience. He knew the fanatical clan-loyalty of the Arabs, knew that Ahmed’s one decent trait had been a fierce devotion for the scoundrel he served. “Follow me.”
With a last glance at the master of the Manor and the black body sprawling like a human sacrifice before him, McGrath left the chamber of torture. Just so, he reflected, one of Ballville’s warrior-king ancestors might have lain in some dim past age, with a slaughtered slave at his feet to serve his spirit in the land of ghosts.
With the Arab at his heels, McGrath emerged into the girdling pines that slumbered in the still heat of the noon. Faintly to his ears a distant pulse of sound was borne by a vagrant drift of breeze. It sounded like the throb of a faraway drum.
“Come on!” McGrath strode through the cluster of outhouses and plunged into the woods that rose behind them. Here, too, had once stretched the fields that built the wealth of the aristocratic Ballvilles; but for many years they had been abandoned. Paths straggled aimlessly through the ragged growth, until presently the growing denseness of the trees told the invaders that they were in forest that had never known the woodsman’s ax. McGrath looked for a path. Impressions received in childhood are always enduring. Memory remains, overlaid by later things, but unerring through the years. McGrath found the path he sought, a dim trace, twisting through the trees.
They were forced to walk single file; the branches scraped their clothing, their feet sank into the carpet of pine needles. The land trended gradually lower. Pines gave way to cypresses, choked with underbrush. Scummy pools of stagnant water glimmered under the trees. Bullfrogs croaked, mosquitoes sang with maddening insistence about them. Again the distant drum throbbed across the pinelands.
McGrath shook the sweat out of his eyes. That drum roused memories well fitted to these somber surroundings. His thoughts reverted to the hideous scar seared on Richard Ballville’s naked breast. Ballville had supposed that he, McGrath, knew its meaning; but he did not. That it portended black horror and madness he knew, but its full significance he did not know. Only once before had he seen that symbol, in the horror-haunted country of Zambebwei, into which few white men had ever ventured, and from which only one white man had ever escaped alive. Bristol McGrath was that man, and he had only penetrated the fringe of that abysmal land of jungle and black swamp. He had not been able to plunge deep enough into that forbidden realm either to prove or to disprove the ghastly tales men whispered of an ancient cult surviving a prehistoric age, of the worship of a monstrosity whose mold violated an accepted law of nature. Little enough he had seen; but what he had seen had filled him with shuddering horror that sometimes returned now in crimson nightmares.
No word had passed between the men since they had left the Manor, McGrath plunged on through the vegetation that choked the path. A fat, blunt-tailed moccasin slithered from under his feet and vanished. Water could not be far away; a few more steps revealed it. They stood on the edge of a dank, slimy marsh from which rose a miasma of rotting vegetable matter. Cypresses shadowed it. The path ended at its edge. The swamp stretched away and away, lost to sight swiftly in twilight dimness.
What now, effendi?” asked Ali. “Are we to swim this morass?”
“It’s full of bottomless quagmires,” answered McGrath. “It would be suicide for a man to plunge into it. Not even the piney woods niggers have ever tried to cross it. But there is a way to get to the hill that rises in the middle of it. You can just barely glimpse it, among the branches of the cypresses, see? Years ago, when Ballville and I were boys — and friends — we discovered an old, old Indian path, a secret, submerged road that led to that hill. There’s a cave in the hill, and a woman is imprisoned in that cave. I’m going to it. Do you want to follow me, or to wait for me here? The path is a dangerous one.”
“I will go, effendi,” answered the Arab.
McGrath nodded in appreciation, and began to scan the trees about him. Presently he found what he was looking for — a faint blaze on a huge cypress, an old mark, almost imperceptible. Confidently then, he stepped into the marsh beside the tree. He himself had made that mark, long ago. Scummy water rose over his shoe soles, but no higher. He stood on a flat rock, or rather on a heap of rocks, the topmost of which was just below the stagnant surface. Locating a certain gnarled cypress far out in the shadow of the marsh, he began walking directly toward it, spacing his strides carefully, each carrying him to a rock-step invisible below the murky water. Ali ibn Suleyman followed him, imitating his motions.
Through the swamp they went, following the marked trees that were their guideposts. McGrath wondered anew at the motives that had impelled the ancient builders of the trail to bring these huge rocks from afar and sink them like piles into the slush. The work must have been stupendous, requiring no mean engineering skill. Why had the Indians built this broken road to Lost Island? Surely that isle and the cave in it had some religious significance to the red men; or perhaps it was their refuge against some stronger foe.
The going was slow; a misstep meant a plunge into marshy ooze, into unstable mire that might swallow a man alive. The island grew out of the trees ahead of them — a small knoll, girdled by a vegetation-choked beach. Through the foliage was visible the rocky wall that rose sheer from the beach to a height of fifty or sixty feet. It was almost like a granite block rising from a flat sandy rim. The pinnacle was almost bare of growth.
McGrath was pale, his breath coming in quick gasps. As they stepped upon the beach-like strip, Ali, with a glance of commiseration, drew a flask from his pocket.
“Drink a little brandy, effendi,” he urged, touching the mouth to his own lips, oriental-fashion. “It will aid you.”
McGrath knew that Ali thought his evident agitation was a result of exhaustion. But he was scarcely aware of his recent exertions. It was the emotions that raged within him — the thought of Constance Brand, whose beautiful form had haunted his troubled dreams for three dreary years. He gulped deeply of the liquor, scarcely tasting it, and handed back the flask.
“Come on!”
The pounding of his own heart was suffocating, drowning the distant drum, as he thrust through the choking vegetation at the foot of the cliff. On the gray rock above the green mask appeared a curious carven symbol, as he had seen it years ago, when its discovery led him and Richard Ballville to the hidden cavern. He tore aside the clinging vines and fronds, and his breath sucked in at the sight of a heavy iron door set in the narrow mouth that opened in the granite wall.
McGrath’s fingers were trembling as they swept over the metal, and behind him he could hear Ali breathing heavily. Some
