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.
