He kept straining his ears in vain for the drum he had heard earlier in the day. The silence did not reassure him. In a voodoo sacrifice drums would be thundering, but he knew he was dealing with something even more ancient and abhorrent than voodoo.
Voodoo was comparatively a young religion, after all, born in the hills of Haiti. Behind the froth of voodooism rose the grim religions of Africa, like granite cliffs glimpsed through a mask of green fronds. Voodooism was a mewling infant beside the black, immemorial colossus that had reared its terrible shape in the older land through uncounted ages, Zambebwei! The very name sent a shudder through him, symbolic of horror and fear. It was more than the name of a country and the mysterious tribe that inhabited that country; it signified something fearfully old and evil, something that had survived its natural epoch —a religion of the Night, and a deity whose name was Death and Horror.
He had seen no negro cabins. He knew these were farther to the east and south, most of them, huddling along the banks of the river and the tributary creeks. It was the instinct of the black man to build his habitation by a river, as he had built by the Congo, the Nile and the Niger since Time's first gray dawn. Zambebwei! The word beat like a throb of a tom-tom through the brain of Bristol McGrath. The soul of the black man had not changed, through the slumberous centuries. Change might come in the clangor of city streets, in the raw rhythms of Harlem; but the swamps of the Mississippi do not differ enough from the swamps of the Congo to work any great transmutation in the spirit of a race that was old before the first white king wove the thatch of his wattled hut-palace.
Following that winding path through the twilight dimness of the big pines, McGrath did not find it in his soul to marvel that black slimy tentacles from the depths of Africa had stretched across the world to breed nightmares in an alien land. Certain natural conditions produce certain effects, breed certain pestilences of body or mind, regardless of their geographical situation. The river-haunted pinelands were as abysmal in their way as were the reeking African jungles.
The trend of the trail was away from the river. The land sloped very gradually upward, and all signs of marsh vanished.
The trail widened, showing signs of frequent use. McGrath became nervous. At any moment he might meet someone. He took to the thick woods alongside the trail, and forced his way onward, each movement sounding cannon-loud to his whetted ears. Sweating with nervous tension, he came presently upon a smaller path, which meandered in the general direction he wished to go. The pinelands were crisscrossed by such paths.
He followed it with greater ease and stealth, and presently, coming to a crook in it, saw it join the main trail. Near the point of junction stood a small log cabin, and between him and the cabin squatted a big black man. This man was hidden behind the bole of a huge pine beside the narrow path, and peering around it toward the cabin. Obviously he was spying on someone, and it was quickly apparent who this was, as John De Albor came to the door and stared despairingly down the wide trail. The black watcher stiffened and lifted his fingers to his mouth as if to sound a far-carrying whistle, but De Albor shrugged his shoulders helplessly and turned back into the cabin again. The negro relaxed, though he did not alter his vigilance.
What this portended, McGrath did not know, nor did he pause to speculate. At the sight of De Albor a red mist turned the sunlight to blood, in which the black body before him floated like an ebony goblin.
A panther stealing upon its kill would have made as much noise as McGrath made in his glide down the path toward the squatting black. He was aware of no personal animosity toward the man, who was but an obstacle in his path of vengeance. Intent on the cabin, the black man did not hear that stealthy approach. Oblivious to all else, he did not move or turn—until the pistol butt descended on his woolly skull with an impact that stretched him senseless among the pine needles.
McGrath crouched above his motionless victim, listening. There was no sound near by—but suddenly, far away, there rose a long-drawn shriek that shuddered and died away. The blood congealed in McGrath's veins. Once before he had heard that sound—in the low forest-covered hills that fringe the borders of forbidden Zambebwei; his black boys had turned the color of ashes and fallen on their faces. What it was he did not know; and the explanation offered by the shuddering natives had been too monstrous to be accepted by a rational mind. They called it the voice of the god of Zambebwei.
Stung to action, McGrath rushed down the path and hurled himself against the back door of the cabin. He did not know how many blacks were inside; he did not care. He was beserk with grief and fury.
