the edge of the cloud, and once again he took his position kneeling beside the ape-man with his blade ready for the moment that the sunlight should flood again, for the last time, the living Tarzan. He saw it sweeping slowly across the boma toward him, and as it came a look of demoniacal hatred shone in his close-set, wicked eyes. Another instant and the Flaming God would have set the seal of his approval upon the sacrifice. Cadj trembled in anticipation. He raised the knife a trifle higher, his muscles tensed for the downward plunge, and then the silence of the jungle was broken by a woman's voice, raised almost to a scream.
'Cadj' came the single word, but with all the suddenness and all the surprising effect of lightning from a clear sky.
His knife still poised on high, the High Priest turned in the direction of the interruption to see at the clearing's edge the figure of La, the High Priestess, and behind her Dooth and a score of the lesser priests.
'What means this, Cadj?' demanded La, angrily, approaching rapidly toward him across the clearing. Sullenly the High Priest rose.
'The Flaming God demanded the life of this unbeliever,' he cried.
'Speaker of lies,' retorted La, 'the Flaming God communicates with men through the lips of his High Priestess only. Too often already have you attempted to thwart the will of your queen. Know, then, Cadj, that the power of life and death which your queen holds is as potent over you as another. During the long ages that Opar has endured, our legends tell us that more than one High Priest has been offered upon the altar to the Flaming God. And it is not unlikely that yet another may go the way of the presumptuous. Curb, therefore, your vanity and your lust for power, lest they prove your undoing.'
Cadj sheathed his knife and turned sullenly away, casting a venomous look at Dooth, to whom he evidently attributed his undoing. That he was temporarily abashed by the presence of his queen was evident, but to those who knew Cadj there was little doubt that he still harbored his intention to despatch the ape-man, and if the opportunity ever presented itself that he would do so, for Cadj had a strong following among the people and priests of Opar. There were many who doubted that La would ever dare to incur the displeasure and anger of so important a portion of her followers as to cause the death or degradation of their high priest, who occupied his office by virtue of laws and customs so old that their origin had been long lost in antiquity.
For years she had found first one excuse and then another to delay the ceremonies that would unite her in marriage to the High Priest. She had further aroused the antagonism of her people by palpable proofs of her infatuation for the ape-man, and even though at last she had been compelled to mate with Cadj, she had made no effort whatsoever to conceal her hatred and loathing for the man. How much further she could go with impunity was a question that often troubled those whose position in Opar depended upon her favor, and, knowing all these conditions as he did, it was not strange that Cadj should entertain treasonable thoughts toward his queen. Leagued with him in his treachery was Oah, a priestess who aspired to the power and offices of La. If La could he done away with, then Cadj had the influence to see that Oah became High Priestess. He also had Oah's promise to mate with him and permit him to rule as king, but as yet both were bound by the superstitious fear of their flaming deity, and because of this fact was the life of La temporarily made safe. It required, however, but the slightest spark to ignite the flames of treason that were smoldering about her.
So far, she was well within her rights in' forbidding the sacrifice of Tarzan by the High Priest. But her fate, her very life, perhaps, depended upon her future treatment of the prisoner. Should she spare him, should she evidence in any way a return of the great love she had once almost publicly avowed for him, it was likely that her doom would be sealed. It was even questionable whether or not she might with impunity spare his life and set him at liberty.
Cadj and the others watched her closely now as she crossed to the side of Tarzan. Standing there silently for several moments she looked down upon him.
'He is already dead?' she asked.
'He was not dead when Cadj sent us away,' volunteered Dooth. 'If he is dead now it is because Cadj killed him while we were away.'
'I did not kill him,' said Cadj. 'That remains, as La, our queen, has told you, for her to do. The eye of the Flaming God looks down upon you, High Priestess of Opar. The knife is at your hip, the sacrifice lies before you.'
La ignored the man's words and turned toward Dooth. 'If he still lives,' she said, 'construct a litter and bear him back to Opar.'
Thus, once more, came Tarzan of the Apes into the ancient colonial city of the Atlantians. The effects of the narcotic that Kraski had administered to him did not wear off for many hours. It was night when he opened his eyes, and for a moment he was bewildered by the darkness and the silence that surrounded him. All that he could scent at first was that he lay upon a pile of furs and that he was uninjured; for he felt no pain. Slowly there broke through the fog of his drugged brain recollection of the last moment before unconsciousness had overcome him, and presently he realized the trick that had been played upon him. For how long he had been unconscious and where he then was he could not imagine. Slowly he arose to his feet, finding that except for a slight dizziness he was quite himself. Cautiously he felt around in the darkness, moving with care, a hand out-stretched, and always feeling carefully with his feet for a secure footing. Almost immediately a stone wall stopped his progress, and this he followed around four sides of what he soon realized was a small room in which there were but two openings, a door upon each of the opposite sides. Only his senses of touch and smell were of value to him here. These told him only at first that he was imprisoned in a subterranean chamber, but as the effects of the narcotic diminished, the keenness of the latter returned, and with its return there was borne in upon Tarzan's brain an insistent impression of familiarity in certain fragrant odors that impinged upon his olfactory organs—a haunting suggestion that he had known them before under similar circumstances. Presently from above, through earth and masonry, came the shadow of an uncanny scream—just the faintest suggestion of it reached the keen ears of the ape-man, but it was sufficient to flood his mind with vivid recollections, and, by association of ideas, to fix the identity of the familiar odors about him. He knew at last that he was in the dark pit beneath Opar.
Above him, in her chamber in the temple, La, the High Priestess, tossed upon a sleepless couch. She knew all too well the temper of her people and the treachery of the High Priest, Cadj. She knew the religious fanaticism which prompted the ofttime maniacal actions of her bestial and ignorant followers, and she guessed truly that Cadj would inflame them against her should she fail this time in sacrificing the ape-man to the Flaming God. And it was the effort to find an escape from her dilemma that left her sleepless, for it was not in the heart of La to sacrifice Tarzan of the Apes. High Priestess of a horrid cult, though she was, and queen of a race of half-beasts, yet she was a woman, too, a woman who had loved but once and given that love to the godlike ape-man who was again within her power. Twice before had he escaped her sacrificial knife; in the final instance love had at last triumphed over jealousy and fanaticism, and La, the woman, had realized that never again could she place in jeopardy the life of the man she loved, however hopeless she knew that love to be.
Tonight she was faced with a problem that she felt almost beyond her powers of solution. The fact that she was mated with Cadj removed the last vestige of hope that she had ever had of becoming the wife of the ape-man. Yet she was no less determined to save Tarzan if it were possible. Twice had he saved her life, once from a mad priest, and once from Tantor in must. Then, too, she had given her word that when Tarzan came again to Opar he came in friendship and would be received in friendship. But the influence of Cadj was great, and she knew that that influence had been directed unremittingly against the ape-man—she had seen it in the attitude of her followers from the very moment that they had placed Tarzan upon a litter to bear him back to Opar—she had seen it in the evil glances that had been cast at her. Sooner or later they would dare denounce her—all that they needed was some slight, new excuse, that, she knew, they eagerly awaited in her forthcoming attitude toward Tarzan. It was well after midnight when there came to her one of the priestesses who remained always upon guard outside her chamber door.
'Dooth would speak with you,' whispered the hand-maiden.
'It is late,' replied La, 'and men are not permitted in this part of the temple. How came he here, and why?'
'He says that he comes in the service of La, who is in great danger,' replied the girl.
'Fetch him here then,' said La, 'and as you value your life see that you tell no one.'
'I shall be as voiceless as the stones of the altar,' replied the girl, as she turned and left the chamber.
A moment later she returned, bringing Dooth, who halted a few feet from the High Priestess and saluted her. La signaled to the girl who had brought him, to depart, and then she turned questioningly to the man.
