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 moccasion 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.
"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 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 fragrange 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.
