“Do not kill me! Do not kill me!” she cried. “It was not I. It was not my fault.”

“I do not intend to kill you,” replied Tarzan. “Tell me the truth and you shall be safe.”

“The Bolgani have taken them away,” cried the woman. “They came when the sun was low upon the day that you arrived, and they were very angry, for they had found the body of their fellow outside the gate of the Palace of Diamonds. They knew that he had come here to our village, and no one had seen him alive since he had departed from the palace. They came, then, and threatened and tortured our people, until at last the warriors told them all. I hid. I do not know why they did not find me. But at last they went away, taking all the others with them; taking your mate, too. They will never come back.”

“You think that the Bolgani will kill them?” asked Tarzan.

“Yes,” she replied, “they kill all who displease them.”

Alone, now, and relieved of the responsibility of La, Tarzan might easily make his way by night through the valley of Opar and to safety beyond the barrier. But perhaps such a thought never entered his head. Gratitude and loyalty were marked characteristics of the ape-man. La had saved him from the fanaticism and intrigue of her people. She had saved him at a cost of all that was most dear to her, power and position, peace and safety. She had jeopardized her life for him, and become an exile from her own country. The mere fact then that the Bolgani had taken her with the possible intention of slaying her, was not sufficient for the ape-man. He must know whether or not she lived, and if she lived he must devote his every energy to winning her release and her eventual escape from the dangers of this valley.

Tarzan spent the day reconnoitering outside the palace grounds, seeking an opportunity of gaining entrance without detection, but this he found impossible inasmuch as there was never a moment that there were not Gomangani or Bolgani in the outer garden. But with the approach of darkness the great east gate was closed, and the inmates of the huts and palace withdrew within their walls, leaving not even a single sentinel without—a fact that indicated clearly that the Bolgani had no reason to apprehend an attack. The subjugation of the Gomangani, then, was apparently complete, and so the towering wall surrounding their palace, which was more than sufficient to protect them from the inroads of lions, was but the reminder of an ancient day when a once-powerful, but now vanished, enemy threatened their peace and safety.

When darkness had finally settled Tarzan approached the gate, and throwing the noose of his grass rope over one of the carved lions that capped the gate posts, ascended quickly to the summit of the wall, from where he dropped lightly into the garden below. To insure an avenue for quick escape in the event that he found La, he unlatched the heavy gates and swung them open. Then he crept stealthily toward the ivy-covered east tower, which he had chosen after a day of investigation as offering easiest ingress to the palace. The success of his plan hinged largely upon the age and strength of the ivy which grew almost to the summit of the tower, and, to his immense relief, he found that it would easily support his weight.

Far above the ground, near the summit of the tower, he had seen from the trees surrounding the palace an open window, which, unlike the balance of those in this part of the palace, was without bars. Dim lights shone from several of the tower windows, as from those of other parts of the palace. Avoiding these lighted apertures, Tarzan ascended quickly, though carefully, toward the unbarred window above, and as he reached it and cautiously raised his eyes above the level of the sill, he was delighted to find that it opened into an unlighted chamber, the interior of which, however, was so shrouded in darkness that he could discern nothing within. Drawing himself carefully to the level of the sill he crept quietly into the apartment beyond. Groping through the blackness, he cautiously made the rounds of the room, which he found to contain a carved bedstead of peculiar design, a table, and a couple of benches. Upon the bedstead were stuffs of woven material, thrown over the softly tanned pelts of antelopes and leopards.

Opposite the window through which he had entered was a closed door. This he opened slowly and silently, until, through a tiny aperture he could look out upon a dimly lighted corridor or circular hallway, in the center of which was an opening about four feet in diameter, passing through which and disappearing beyond a similar opening in the ceiling directly above was a straight pole with short crosspieces fastened to it at intervals of about a foot—quite evidently the primitive staircase which gave communication between the various floors of the tower. Three upright columns, set at equal intervals about the circumference of the circular opening in the center of the floor helped to support the ceiling above. Around the outside of this circular hallway there were other doors, similar to that opening into the apartment in which he was.
