Chapter 25

For a brief, sickening moment Tarzan felt the slipping of the rope to which he clung, and heard the scraping of the block of stone against the masonry above.

Then of a sudden the rope was still--the stone had caught at the very edge. Gingerly the ape-man clambered up the frail rope. In a moment his head was above the edge of the shaft. The court was empty. The inhabitants of Opar were viewing the sacrifice. Tarzan could hear the voice of La from the nearby sacrificial court. The dance had ceased. It must be almost time for the knife to fall; but even as he thought these things he was running rapidly toward the sound of the high priestess' voice.

Fate guided him to the very doorway of the great roofless chamber. Between him and the altar was the long row of priests and priestesses, awaiting with their golden cups the spilling of the warm blood of their victim. La's hand was descending slowly toward the bosom of the frail, quiet figure that lay stretched upon the hard stone. Tarzan gave a gasp that was almost a sob as he recognized the features of the girl he loved. And then the scar upon his forehead turned to a flaming band of scarlet, a red mist floated before his eyes, and, with the awful roar of the bull ape gone mad, he sprang like a huge lion into the midst of the votaries.

Seizing a cudgel from the nearest priest, he laid about him like a veritable demon as he forged his rapid way toward the altar. The hand of La had paused at the first noise of interruption. When she saw who the author of it was she went white. She had never been able to fathom the secret of the strange white man's escape from the dungeon in which she had locked him. She had not intended that he should ever leave Opar, for she had looked upon his giant frame and handsome face with the eyes of a woman and not those of a priestess.

In her clever mind she had concocted a story of wonderful revelation from the lips of the flaming god himself, in which she had been ordered to receive this white stranger as a messenger from him to his people on earth. That would satisfy the people of Opar, she knew. The man would be satisfied, she felt quite sure, to remain and be her husband rather than to return to the sacrificial altar.

But when she had gone to explain her plan to him he had disappeared, though the door had been tightly locked as she had left it. And now he had returned--materialized from thin air--and was killing her priests as though they had been sheep. For the moment she forgot her victim, and before she could gather her wits together again the huge white man was standing before her, the woman who had lain upon the altar in his arms.

"One side, La," he cried. "You saved me once, and so I would not harm you; but do not interfere or attempt to follow, or I shall have to kill you also."

As he spoke he stepped past her toward the entrance to the subterranean vaults.

"Who is she?" asked
