The thing chained to the stake was an ape, but such an ape as the world at large never dreamed of, even in nightmares. Its shaggy gray hair was shot with silver that shone in the rising moon; it looked gigantic as it squatted ghoulishly on its haunches. Upright, on its bent, gnarled legs, it would be as tall as a man, and much broader and thicker. But its prehensile fingers were armed with talons like those of a tiger—not the heavy blunt nails of the natural anthropoid, but the cruel simitar-curved claws of the great carnivora. Its face was like that of a gorilla, low browed, flaring-nostriled, chinless; but when it snarled, its wide flat nose wrinkled like that of a great cat, and the cavernous mouth disclosed saber-like fangs, the fangs of a beast of prey. This was Zemba, the creature sacred to the people of the land of Zambebwei—a monstrosity, a violation of an accepted law of nature —a carnivorous ape. Men had laughed at the story, hunters and zoologists and traders.
But now McGrath knew that such creatures dwelt in black Zambebwei and were worshipped, as primitive man is prone to worship an obscenity or perversion of nature. Or a survival of past eons: that was what the flesh- eating apes of Zambebwei were—survivors of a forgotten epoch, remnants of a vanished prehistoric age, when nature was experimenting with matter, and life took many monstrous forms.
The sight of the monstrosity filled McGrath with revulsion; it was abysmal, a reminder of that brutish and horrorshadowed past out of which mankind crawled so painfully, eons ago. This thing was an affront to sanity; it belonged in the dust of oblivion with the dinosaur, the mastodon, and the saber- toothed tiger.
It looked massive beyond the stature of modern beasts-shaped on the plan of another age, when all things were cast in a mightier mold. He wondered if the revolver at his hip would have any effect on it; wondered by what dark and subtle means John De Albor had brought the monster from Zambebwei to the pinelands.
But something was happening in the glade, heralded by the shaking of the brute's chain as it thrust forward its nightmare=head.
From the shadows of the trees came a file of black men and women, young, naked except for a mantle of monkeyskins and parrot-feathers thrown over the shoulders of each. More regalia brought by John De Albor, undoubtedly. They formed a semicircle at a safe distance from the chained brute, and sank to their knees, bending their heads to the ground before him. Thrice this motion was repeated. Then, rising, they formed two lines, men and women facing one another, and began to dance; at least it might by courtesy be called a dance. They hardly moved their feet at all, but all other parts of their bodies were in constant motion, twisting, rotating, writhing. The measured, rhythmical movements had no connection at all with the voodoo dances McGrath had witnessed. This dance was disquietingly archaic in its suggestion, though even more depraved and bestial—naked primitive passions framed in a cynical debauchery of motion.
No sound came from the dancers, or from the votaries squatting about the ring of trees. But the ape, apparently infuriated by the continued movements, lifted his head and sent into the night the frightful shriek McGrath had heard once before that day—he had heard it in the hills that border black Zambebwei. The brute plunged to the end of his heavy chain, foaming and gnashing his fangs, and the dancers fled like spume blown before a gust of wind. They scattered in all directions—and then McGrath started up in his covert, barely stifling a cry.
From the deep shadows had come a figure, gleaming tawnily in contrast to the black forms about it. It was John De Albor, naked except for a mantle of bright feathers, and on his head a circlet of gold that might have been forged in Atlantis. In his hand he bore a gold wand that was the scepter of the high priests of Zambebwei.
Behind him came a pitiful figure, at the sight of which the moon-lit forest reeled to McGrath's sight.
Constance had been drugged. Her face was that of a sleep-walker; she seemed not aware of her peril, or the fact that she was naked. She walked like a robot, mechanically responding to the urge of the cord tied about her white neck. The other end of that cord was in John De Albor's hand, and he half led, half dragged her toward the horror that squatted in the center of the glade. De Albor's face was ashy in the moonlight that now flooded the glade with molten silver. Sweat beaded his skin. His eyes gleamed with fear and ruthless determination. And in a staggering instant McGrath knew that the man had failed, that he had been unable to save Constance, and that now, to save his own life from his suspicious followers, he himself was dragging the girl to the gory sacrifice.
No vocal sound came from the votaries, but hissing intake of breath sucked through thick lips, and the rows of black bodies swayed like reeds in the wind. The great ape leaped up, his face a slavering devil's mask; he howled with frightful eagerness, gnashing his great fangs, that yearned to sink into that soft white flesh, and the hot blood beneath. He surged against his chain, and the stout post quivered. McGrath, in the bushes, stood frozen, paralyzed by the imminence of horror. And then John De Albor stepped behind the unresisting girl and gave her a powerful push that sent her reeling forward to pitch headlong on the ground under the monster's talons.
And simultaneously McGrath moved. His move was instinctive rather than conscious. His .44 jumped into his hand and spoke, and the great ape screamed like a man death-stricken and reeled, clapping misshapen hands to its head.
An instant the throng crouched frozen, white eyes bulging, jaws hanging slack. Then before any could move, the ape, blood gushing from his head, wheeled, seized the chain in both hands and snapped it with a wrench that twisted the heavy links apart as if they had been paper.
John De Albor stood directly before the mad brute, paralyzed in his tracks. Zemba raored and leaped, and the african went down under him, disembowled by the razorlike talons, his head crushed to a crimson pulp by a sweep of the great paw.
Ravening, the monster charged among the votaries, clawing and ripping and smiting, screaming intolerably. Zambebwei spoke, and death was in his bellowing Screaming, howling, fighting, the black people scrambled over one another in their mad flight. Men and women went down under those shearing talons, were dismembered by those gnashing fangs. It was a red drama of the primitive —destruction amuck and ariot, the primordial embodied in fangs and talons, gone mad and plunging in slaughter. Blood and brains deluged the earth, black bodies and limbs and fragments of bodies littered the moonlighted glade in ghastly heaps before the last of the howling wretches found refuge among the trees. The sounds of their blundering, panic-stricken flight drifted back.
McGrath had leaped from his covert almost as soon as he had fired. Unnoticed by the terrified negroes, and himself scarcely cognizant of the slaughter raging around him, he raced across the glade toward the pitiful white figure that lay limply beside the iron-bound stake.
"Constance!" he cried, gathering her to his breast.
Languidly she opened her cloudy eyes. He held her close, heedless of the screams and devastation surging about them. Slowly recognition grew in those lovely eyes.
"Bristol!" she murmured, incoherently. Then she screamed, clung to him, sobbing hysterically. "Bristol! They told me you were dead! The blacks! The horrible blacks! They're going to kill me! They were going to kill De Albor too, but he promised to sacrifice—"
"Don't, girl, don't!" He subdued her frantic tremblings. "It's all right, now—" Abruptly he looked up into the grinning bloodstained face of nightmare and death. The great ape had ceased to rend his dead victims and was slinking toward the living pair in the center of the glade. Blood oozed from the wound in its sloping skull that had maddened it.
