De Albor retched and fought for breath, ashen-faced. “The blacks!” he gasped. “They have taken her to be the Bride of Zemba! I could not prevent them. They demand a sacrifice. I offered them you, but they said you were paralyzed and would die anyway — they were cleverer than I thought. They followed me back to the Manor from the spot where we left the Arab in the road — followed us from the Manor to the island.
“They are out of hand — mad with blood-lust. But even I, who know black men as none else knows them, I had forgotten that not even a priest of Zambebwei can control them when the fire of worship runs in their veins. I am their priest and master — yet when I sought to save the girl, they forced me into this cabin and set a man to watch me until the sacrifice is over. You must have killed him; he would never have let you enter here.”
With a chill grimness, McGrath picked up his pistol.
“You came here as Richard Ballville’s friend,” he said unemotionally. “To get possession of Constance Brand, you made devil-worshippers out of the black people. You deserve death for that. When the European authorities that govern Africa catch a priest of Zambebwei, they hang him. You have admitted that you are a priest. Your life is forfeit on that score, too. But it is because of your hellish teachings that Constance Brand is to die, and it’s for that reason that I’m going to blow out your brains.”
John De Albor shriveled. “She is not dead yet,” he gasped, great drops of perspiration dripping from his ashy face. “She will not die until the moon is high above the pines. It is full tonight, the Moon of Zambebwei. Don’t kill me. Only I can save her. I know I failed before. But if I go to them, appear to them suddenly and without warning, they’ll think it is because of supernatural powers that I was able to escape from the hut without being seen by the watchman. That will renew my prestige.
“You can’t save her. You might shoot a few blacks, but there would still be scores left to kill you — and her. But I have a plan — yes, I am a priest of Zambebwei. When I was a boy I ran away from my Arab master and wandered far until I came to the land of Zambebwei. There I grew to manhood and became a priest, dwelling there until the white blood in me drew me out in the world again to learn the ways of the white men. When I came to America I brought a Zemba with me — I can not tell you how. . . .
“Let me save Constance Brand!” He was clawing at McGrath, shaking as if with an ague. “I love her, even as you love her. I will play fair with you both, I swear it! Let me save her! We can fight for her later, and I’ll kill you if I can.”
The frankness of that statement swayed McGrath more than anything else the octoroon could have said. It was a desperate gamble — but after all, Constance would be no worse off with John De Albor alive than she was already. She would be dead before midnight unless something was done swiftly.
“Where is the place of sacrifice?” asked McGrath.
“Three miles away, in an open glade,” answered De Albor. “South on the trail that runs past my cabin. All the blacks are gathered there except my guard and some others who are watching the trail below the cabin. They are scattered out along it, the nearest out of sight of my cabin, but within sound of the loud, shrill whistle with which these people signal one another.
“This is my plan. You wait here in my cabin, or in the woods, as you choose. I’ll avoid the watchers on the trail, and appear suddenly before the blacks at the House of Zemba. A sudden appearance will impress them deeply, as I said. I know I can not persuade them to abandon their plan, but I will make them postpone the sacrifice until just before dawn. And before that time I will manage to steal the girl and flee with her. I’ll return to your hiding-place, and we’ll fight our way out together.”
McGrath laughed. “Do you think I’m an utter fool? You’d send your blacks to murder me, while you carried Constance away as you planned. I’m going with you. I’ll hide at the edge of the clearing, to help you if you need help. And if you make a false move, I’ll get you, if I don’t get anybody else.”
The octoroon’s murky eyes glittered, but he nodded acquiescence.
“Help me bring your guard into the cabin,” said McGrath. “He’ll be coming to soon. We’ll tie and gag him and leave him here.”
* * * *
The sun was setting and twilight was stealing over the pinelands as McGrath and his strange companion stole through the shadowy woods. They had circled to the west to avoid the watchers on the trail, and were now following on the many narrow footpaths which traced their way through the forest. Silence reigned ahead of them, and McGrath mentioned this.
“Zemba is a god of silence,” muttered De Albor. “From sunset to sunrise on the night of the full moon, no drum is beaten. If a dog barks, it must be slain; if a baby cries, it must be killed. Silence locks the jaws of the people until Zemba roars. Only his voice is lifted on the night of the Moon of Zemba.”
McGrath shuddered. The foul deity was an intangible spirit, of course, embodied only in legend; but De Albor spoke of it as a living thing.
A few stars were blinking out, and shadows crept through the thick woods, blurring the trunks of the trees that melted together in darkness. McGrath knew they could not be far from the House of Zemba. He sensed the close presence of a throng of people, though he heard nothing.
De Albor, ahead of him, halted suddenly, crouching. McGrath stopped, trying to pierce the surrounding mask of interlacing branches.
“What is it?” muttered the white man, reaching for his pistol.
De Albor shook his head, straightening. McGrath could not see the stone in his hand, caught up from the earth as he stooped.
“Do you hear something?” demanded McGrath.
De Albor motioned him to lean forward, as if to whisper in his ear. Caught off his guard, McGrath bent toward him — even so he divined the treacherous African’s intention, but it was too late. The stone in De Albor’s hand crashed sickeningly against the white man’s temple. McGrath went down like a slaughtered ox, and De Albor sped away down the path to vanish like a ghost in the gloom.
5. The Voice of Zemba
In the darkness of the woodland path McGrath stirred at last, and staggered groggily to his feet. That desperate blow might have crushed the skull of a man whose physique and vitality were not that of a bull. His head throbbed and there was dried blood on his temple; but his strongest sensation was burning scorn at himself for having again fallen victim to John De Albor. And yet, who would have suspected that move? He knew De Albor would kill him if he could, but he had not expected an attack before the rescue of Constance. The fellow was dangerous and unpredictable as a cobra. Had his pleas to be allowed to attempt Constance’s rescue been but a ruse to escape death at the hands of McGrath?
McGrath stared dizzily at the stars that gleamed through the ebon branches, and sighed with relief to see that the moon had not yet risen. The pinewoods were black as only pinelands can be, with a darkness that was almost tangible, like a substance that could be cut with a knife.
McGrath had reason to be grateful for his rugged constitution. Twice that day had John De Albor outwitted him, and twice the white man’s iron frame had survived the attack. His gun was in his scabbard, his knife in its sheath. De Albor had not paused to search, had not paused for a second stroke to make sure. Perhaps there had been a tinge of panic in the African’s actions.
Well, this did not change matters a great deal. He believed that De Albor would make an effort to save the girl. And McGrath intended to be on hand, whether to play a lone hand, or to aid the octoroon. This was no time to hold grudges, with the girl’s life at stake. He groped down the path, spurred by a rising glow in the east.
He came upon the glade almost before he knew it. The moon hung in the low branches, blood-red, high enough to illumine it and the throng of black people who squatted in a vast semicircle about it, facing the moon. Their rolling eyes gleamed milkily in the shadows, their features were grotesque masks. None spoke. No head
