A minute passed; a second, and a third, and then the hangings were thrust aside and a grimly masked priest of the temple of Jad-ben-Otho strode into the passageway.

With bold steps he moved along and was about to turn into a diverging gallery when his attention was aroused by voices coming from a room upon his left. Instantly the figure halted and crossing the corridor stood with an ear close to the skins that concealed the occupants of the room from him, and him from them. Presently he leaped back into the concealing shadows of the diverging gallery and immediately thereafter the hangings by which he had been listening parted and a priest emerged to turn quickly down the main corridor. The eavesdropper waited until the other had gained a little distance and then stepping from his place of concealment followed silently behind.

The way led along the corridor which ran parallel with the face of the cliff for some little distance and then Pan-sat, taking a cresset from one of the wall niches, turned abruptly into a small apartment at his left. The tracker followed cautiously in time to see the rays of the flickering light dimly visible from an aperture in the floor before him. Here he found a series of steps, similar to those used by the Waz-don in scaling the cliff to their caves, leading to a lower level.

First satisfying himself that his guide was continuing upon his way unsuspecting, the other descended after him and continued his stealthy stalking. The passageway was now both narrow and low, giving but bare headroom to a tall man, and it was broken often by flights of steps leading always downward. The steps in each unit seldom numbered more than six and sometimes there was only one or two but in the aggregate the tracker imagined that they had descended between fifty and seventy-five feet from the level of the upper corridor when the passageway terminated in a small apartment at one side of which was a little pile of rubble.

Setting his cresset upon the ground, Pan-sat commenced hurriedly to toss the bits of broken stone aside, presently revealing a small aperture at the base of the wall upon the opposite side of which there appeared to be a further accumulation of rubble. This he also removed until he had a hole of sufficient size to permit the passage of his body, and leaving the cresset still burning upon the floor the priest crawled through the opening he had made and disappeared from the sight of the watcher hiding in the shadows of the narrow passageway behind him.

No sooner, however, was he safely gone than the other followed, finding himself, after passing through the hole, on a little ledge about halfway between the surface of the lake and the top of the cliff above. The ledge inclined steeply upward, ending at the rear of a building which stood upon the edge of the cliff and which the second priest entered just in time to see Pan-sat pass out into the city beyond.

As the latter turned a nearby corner the other emerged from the doorway and quickly surveyed his surroundings. He was satisfied the priest who had led him hither had served his purpose in so far as the tracker was concerned. Above him, and perhaps a hundred yards away, the white walls of the palace gleamed against the northern sky. The time that it had taken him to acquire definite knowledge concerning the secret passageway between the temple and the city he did not count as lost, though he begrudged every instant that kept him from the prosecution of his main objective. It had seemed to him, however, necessary to the success of a bold plan that he had formulated upon overhearing the conversation between Lu-don and Pan-sat as he stood without the hangings of the apartment of the high priest.

Alone against a nation of suspicious and half-savage enemies he could scarce hope for a successful outcome to the one great issue upon which hung the life and happiness of the creature he loved best. For her sake he must win allies and it was for this purpose that he had sacrificed these precious moments, but now he lost no further time in seeking to regain entrance to the palace grounds that he might search out whatever new prison they had found in which to incarcerate his lost love.

He found no difficulty in passing the guards at the entrance to the palace for, as he had guessed, his priestly disguise disarmed all suspicion. As he approached the warriors he kept his hands behind him and trusted to fate that the sickly light of the single torch which stood beside the doorway would not reveal his un-Pal-ul-donian feet. As a matter of fact so accustomed were they to the comings and goings of the priesthood that they paid scant attention to him and he passed on into the palace grounds without even a moment's delay.

His goal now was the Forbidden Garden and this he had little difficulty in reaching though he elected to enter it over the wall rather than to chance arousing any suspicion on the part of the guards at the inner entrance, since he could imagine no reason why a priest should seek entrance there thus late at night.

He found the garden deserted, nor any sign of her he sought. That she had been brought hither he had learned from the conversation he had overheard between Lu-don and Pan-sat, and he was sure that there had been no time or opportunity for the high priest to remove her from the palace grounds. The garden he knew to be devoted exclusively to the uses of the princess and her women and it was only reasonable to assume therefore that if Jane had been brought to the garden it could only have been upon an order from Ko-tan. This being the case the natural assumption would follow that he would find her in some other portion of O-lo-a's quarters.

Just where these lay he could only conjecture, but it seemed reasonable to believe that they must be adjacent to the garden, so once more he scaled the wall and passing around its end directed his steps toward an entrance-way which he judged must lead to that portion of the palace nearest the Forbidden Garden.

To his surprise he found the place unguarded and then there fell upon his ear from an interior apartment the sound of voices raised in anger and excitement. Guided by the sound he quickly traversed several corridors and chambers until he stood before the hangings which separated him from the chamber from which issued the sounds of altercation. Raising the skins slightly he looked within. There were two women battling with a Ho-don warrior. One was the daughter of Ko-tan and the other Pan-at-lee, the Kor-ul-ja.

At the moment that Tarzan lifted the hangings, the warrior threw O-lo-a viciously to the ground and seizing Pan-at-lee by the hair drew his knife and raised it above her head. Casting the encumbering headdress of the dead priest from his shoulders the ape-man leaped across the intervening space and seizing the brute from behind struck him a single terrible blow.

As the man fell forward dead, the two women recognized Tarzan simultaneously. Pan-at-lee fell upon her knees and would have bowed her head upon his feet had he not, with an impatient gesture, commanded her to rise. He had no time to listen to their protestations of gratitude or answer the numerous questions which he knew would soon be flowing from those two feminine tongues.

"Tell me," he cried, "where is the woman of my own race whom Ja-don brought here from the temple?"

"She is but this moment gone," cried O-lo-a. "Mo-sar, the father of this thing here," and she indicated the body of Bu-lot with a scornful finger, "seized her and carried her away."

"Which way?" he cried. "Tell me quickly, in what direction he took her."

"That way," cried Pan-at-lee, pointing to the doorway through which Mo-sar had passed. "They would have taken the princess and the stranger woman to Tu-lur, Mo-sar's city by the Dark Lake."

"I go to find her," he said to Pan-at-lee, "she is my mate.
