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 builded 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 piny 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 rockstep 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 guide-posts. 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.
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 of the white man's excitement had imparted itself to the Arab. McGrath's hands found the three knobs, forming the apices of a triangle-mere protuberances, not apparent to the sight. Controlling his jumping nerves, he pressed them as Ballville had instructed him, and felt each give slightly at the third pressure. Then, holding his breath, he grasped the bar that was welded in the middle of the door, and pulled. Smoothly, on oiled hinges, the massive portal swung open.
They looked into a wide tunnel that ended in another door, this a grille of steel bars. The tunnel was not dark; it was clean and roomy, and the ceiling had been pierced to allow light to enter, the holes covered with screens to keep out insects and reptiles. But through the grille he glimpsed something that sent him racing along the tunnel, his heart almost bursting through his ribs. Ali was close at his heels.
The grille-door was not locked. It swung outward under his fingers. He stood motionless, almost stunned with the impact of his emotions.
His eyes were dazzled by a gleam of gold; a sunbeam slanted down through the pierced rock roof and struck mellow fire from the glorious profusion of golden hair that flowed over the white arm that pillowed the beautiful head on the carved oak table.
"Constance!" It was a cry of hunger and yearning that burst from his livid lips.
Echoing the cry, the girl started up, staring wildly, her hands at her temples, her lambent hair rippling over her shoulders. To his dizzy gaze she seemed to float in an aureole of golden light.
"Bristol! Bristol McGrath!" she echoed his call with a haunting, incredulous cry. Then she was in his arms, her white arms clutching him in a frantic embrace, as if she feared he were but a phantom that might vanish from her.
For the moment the world ceased to exist for Bristol McGrath. He might have been blind, deaf and dumb to the universe at large. His dazed brain was cognizant only of the woman in his arms, his senses drunken' with the softness and fragrance of her, his soul stunned with the overwhelming realization of a dream he had thought dead and vanished for ever.
When he could think consecutively again, he shook himself like a man coming out of a trance, and stared stupidly around him. He was in a wide chamber, cut in the solid rock. Like the tunnel, it was illumined from above, and the air was fresh and clean. There were chairs, tables and a hammock, carpets on the rocky floor, cans of food and a water-cooler. Ballville had not failed to provide for his captive's comfort. McGrath glanced around at the Arab, and saw him beyond the grille. Considerately he had not intruded upon their reunion.
"Three years!" the girl was sobbing. "Three years I've waited. I knew you'd come! I knew it! But we must be careful, my darling. Richard will kill you if he finds you, kill us both!"
"He's beyond killing anyone," answered McGrath. "But just the same, we've got to get out of here."
Her eyes flared with new terror.
"Yes! John De Albor! Ballville was afraid of him. That's why he locked me in here. He said he'd sent for you. I was afraid for you-"
"Ali!" McGrath called. "Come in here. We're getting out of here now, and we'd better take some water and food with us. We may have to hide in the swamps for-" Abruptly Constance shrieked, tore herself from her lover's arms. And McGrath, frozen by the sudden, awful fear in her wide eyes, felt the dull jolting impact of a savage blow at the base of his skull. Consciousness did not leave him, but a strange paralysis gripped him. He dropped like an empty sack on the stone floor and lay there like a dead man, helplessly staring up at the scene which tinged his brain with madness-Constance struggling frenziedly in the grasp of the man he had known as Ali ibn Suleyman, now terribly transformed.
The man had thrown off his turban and glasses. And in the murky whites of his eyes, McGrath read the truth with its grisly implications-the man was not an Arab. He was a negroid mixed breed. Yet some of his blood must have been Arab, for there was a slightly Semitic cast to his countenance, and this cast, together with his oriental garb and his perfect acting of his part, had made him seem genuine. But now all this was discarded and the negroid strain was uppermost; even his voice, which had enunciated the sonorous Arabic, was now the throaty gutturals of the negro.
"You've killed him!" the girl sobbed hysterically, striving vainly to break away from the cruel fingers that prisoned her white wrists.
"He's not dead yet," laughed the octoroon. "The fool quaffed drugged brandy-a drug found only in the Zambebwei jungles. It lies inactive in the system until made effective by a sharp blow on a nerve center."
"Please do something for him!" she begged.
The fellow laughed brutally.
"Why should I? He has served his purpose. Let him lie there until the swamp insects have picked his bones. I should like to watch that-but we will be far away before nightfall." His eyes blazed with the bestial gratification of possession. The sight of this white beauty struggling in his grasp seemed to rouse all the jungle lust in the man. McGrath's wrath and agony found expression only in his bloodshot eyes. He could not move hand or foot.
"It was well I returned alone to the Manor," laughed the octoroon. "I stole up to the window while this fool talked with Richard Ballville. The thought came to me to let him lead me to the place where you were hidden. It had never occurred to me that there was a hiding-place in the swamp. I had the Arab's coat, slippers and turban; I had thought I might use them sometime. The glasses helped, too. It was not difficult to make an Arab out of myself. This man had never seen John De Albor. I was born in East Africa and grew up a slave in the house of an Arab before I ran away and wandered to the land of Zambebwei.
"But enough. We must go. The drum has been muttering all day. The blacks are restless. I promised them a sacrifice to Zemba. I was going to use the Arab, but by the time I had tortured out of him the information I desired, he was no longer fit for a sacrifice. Well, let them bang their silly drum. They'd like to have you for the Bride of Zemba, but they don't know I've found you. I have a motor-boat hidden on the river five miles from here-"
"You fool!" shrieked Constance, struggling passionately. "Do you think you can carry a white girl down the river, like a slave?"
"I have a drug which will make you like a dead woman," he said. "You will lie in the bottom of the boat, covered by sacks. When I board the steamer that shall bear us from these shores, you will go into my cabin in a large, well-ventilated trunk. You will know nothing of the discomforts of the voyage. You will awake in Africa--"
He was fumbling in his shirt, necessarily releasing her with one hand. With a frenzied scream and a desperate wrench, she tore loose and sped out through the tunnel. John De Albor plunged after her, bellowing. A red haze floated before McGrath's maddened eyes. The girl would plunge to her death in the swamps, unless she remembered the guide-marks--perhaps it was death she sought, in preference to the fate planned for her by the fiendish negro.
They had vanished from his sight, out of the tunnel; but suddenly Constance screamed again, with a new poignancy. To McGrath's ears came an excited jabbering of negro gutturals. De Albor's accents were lifted in angry protest. Constance was sobbing hysterically. The voices were moving away. McGrath got a vague glimpse of a group of figures through the masking vegetation as they moved across the line of the tunnel mouth. He saw Constance being dragged along by half a dozen giant blacks typical pineland dwellers, and after them came John De Albor, his hands eloquent in dissension. That glimpse only, through the fronds, and then the tunnel mouth gaped empty and the sound of splashing water faded away through 'the marsh.
