While Herkuf hastened on toward the air chamber, the warriors hesitated in the throne room, appalled by the bloody shambles that met their astonished view and confused by the fact that the three who faced them appeared to be ptomes of the temple; but at last, seeing no other enemy, the officer in charge of Atka's warriors ordered them forward; while out of sight, Herkuf worked feverishly with the controls of the air chamber, spinning valve handles and pulling levers.
Shouting now, the warriors came steadily down the length of the throne room toward the forlorn hope making a last stand before over-whelming odds; and the warriors looked for an easy victory. Nor were they alone in this belief, which was shared by the three who opposed them.
As the warriors closed upon the three, Tarzan met the leader in a duel between spear and trident, while d'Arnot and Lavac stood upon either side of him, determined, as was the ape-man, to sell their lives dearly; and as they fought thus, there was a sudden rush of water through the doorway behind them.
Herkuf had thought and acted quickly in the emergency that had confronted them, taking advantage of the only means whereby he and his companions could be saved from the vengeance of the warriors. Throwing open both doors of the air chamber, he had let the waters of Horus pour in to fill the temple.
Safe in their water suits, Tarzan, d'Arnot, and Lavac watched the gushing torrent drive back their foes, as, cursing and yelling, the warriors of Ashair sought to climb over one another in their mad panic to escape the watery death Herkuf had loosed upon them out of sacred Horus; but not one escaped as the water filled the throne room and rose through the upper chambers of the temple. It was a gruesome sight from which the three turned gladly at a signal from Tarzan and followed him toward the air chamber, beyond which he had left Helen waiting in the garden of the ptomes.
Chapter 30
UP AND UP through the waters of Horus, Helen was dragged by the ghostly figure until, at last, they reached the precipitous cliff, the summit of which forms the coast line near Ashair. Here the creature dragged his captive into the mouth of a dark cavern, a den of horror to the frightened girl.
Magra and Gregory had been held captives in the cavern for a night and a day waiting for the return of the true god, Chon, who was to decide their fate. They had not been ill treated; and they had been given food, but always there was the feeling of menace. It was in the air, in the strange garmenture of their captors, in their whisperings and in their silences. It affected both Magra and Gregory similarly, leaving them blue and despondent.
They were sitting beside the pool in the center of the cavern almost exactly twenty-four hours after their capture, the white robed figures crouching around them, when there was a sudden breaking of the still surface of the water and two grotesque diving helmets appeared, one white, the other dark.
"The true god has returned," cried one of the priests.
"Now the strangers shall be judged, and punishment meted out to them."
As the two figures emerged from the pool and removed their helmets, Magra and Gregory gasped in astonishment.
"Helen!" cried the latter. "Thank God that you still live. I had given you up for dead."
"Father!" exclaimed the girl. "What are you doing here? Tarzan told us that you and Magra were prisoners in Thobos."
"We escaped," said Magra, "but perhaps we would have been better off there. God only knows what we face here."
The figure in white that had emerged with Helen proved, when he removed his helmet, to be an old man with a bushy white beard. He looked at Helen in astonishment.
"A girl!" he cried. "Since when has false Brulor made ptomes of girls?"
"I am not a ptome," replied Helen. "I was a prisoner of Brulor, and adopted this method to escape."
"Perhaps she lies," said a priest.
"If these be enemies," said the old man, "I shall know when I consult the oracle in the entrails of the man. If they be not enemies, the girls shall become my handmaidens; but if they be, they shall die as the man dies, on the altar of the true god Chon and lost Father of Diamonds."
"And if you find that we are not enemies," demanded Magra, "what good will that do this man, whom you will have already killed? We tell you that we are friends, meaning you no harm. Who are you to say that we are not? Who are you to kill this good man?" Her voice was vibrant with just anger.
"Silence, woman!" commanded a priest. "You are speaking to Chon, the true god."
"If he were any sort of a god at all," snapped Magra, "he would know that we are not enemies. He would not have cut up an innocent man and ask questions of his entrails."
"You do not understand," said Chon, indulgently. "If the man is innocent and has told the truth, he will not die when I remove his entrails. If he dies, that will prove his guilt."
Magra stamped her foot. "You are no god at all," she cried. "You are just a wicked old sadist."
Several priests sprang forward threateningly, but Chon stopped them with a gesture. "Do not harm her," he said; "she knows not what she says. When we have taught her to know the truth, she will be contrite. I am sure that she will become a worthy handmaiden, for she has loyalty and great courage. Treat them all well while they are among us waiting for the hour of inquisition."
Atan Thome fled upward along the secret passageway from the temple of Brulor, hugging the precious casket to his breast; and behind him came Lal Taask, his mind aflame with what was now the one obsession of his life—the killing of his erstwhile master. Secondary to that was his desire to possess the great diamond which reposed in the jeweled casket. Ahead of him he could hear the screams and jibberings of the madman, which served to inflame his rage still further. And behind them both came Brian Gregory, all his fine resolutions forgotten now that The Father of Diamonds seemed almost within his grasp. He knew that he might have to commit murder to obtain it; but that did not deter him in the least, for his avarice, like that of many men, bordered almost upon madness.
Out into the open and along the rocky hillside fled Atan Thome. When Lal Taask reached the open, he saw his quarry scarce a hundred yards ahead of him. Other eyes saw them both, the eyes of Ungo the great bull ape, which, with his fellows, hunted for lizards among the great rocks farther up the hillside. The sight of the two men, the screaming of Atan Thome, excited him. He recalled that Tarzan had told him that they must not attack men unless he were attacked; but there had been no interdiction against joining in their play, and this looked like play to Ungo. It was thus that playful apes chased one another. Of course, Ungo was a little old for play, being a sullen, surly old bull; but he was still imitative, and what the tarmangani did, he desired to do. His fellows were imbued with the same urge toward emulation.
As Brian Gregory came out into the open from the mouth of the secret passageway, he saw the great apes, jabbering with excitement, bounding down the hillside toward Atan Thome and the pursuing Lal Taask. He saw the men stop and then turn and flee in terror from the mighty beast-men charging down upon them.
For the moment Lal Taask discarded all thoughts of vengeance, as the first law of Nature dominated and directed him; but Atan Thome clung tenaciously to his precious casket. Ungo was delighted with this new game, as he came bounding after the fleeing, screaming Thorne, whom he easily overtook. The man, thinking that death was upon him, tried to beat off the ape with one hand while he clung tightly to the casket with the other; that, he would not give up, even in death. Killing, however, was not in the mind of the anthropoid. It was the game in which he was interested; so he snatched the casket from the screaming man as easily as one man takes another's wife in Hollywood , and went bounding off, hoping that some one would pursue him that the game might continue.
