"The ground level of the palace is a busy place, people are coming and going constantly through the corridors. Doubtless some of the upper levels are less frequented. Let us therefore seek a hiding place higher up and from the vantage point of some balcony we may be able to work out a feasible plan of escape." "Good!" he said. "Lead on!" Ascending the winding ramp from the lower pits, we passed two levels before we reached the ground level of the palace, without meeting a single person, but the instant that we emerged upon the ground level we saw people everywhere; officers, courtiers, warriors, slaves and merchants moved to and fro upon their various duties or in pursuit of the business that had brought them to the palace, but their very numbers proved a safeguard for us. Upon the side of the corridor opposite from the point at which we entered it lay an arched entrance to another ramp running upward. Without an instant's hesitation I crossed through the throng of people, and, with Nur An at my side, passed beneath the arch and entered the ascending ramp. Scarcely had we started upward when we met a young officer descending. He accorded us scarcely a glance as we passed and I breathed more easily as I realized that our disguises did, in fact, disguise us. There were fewer people on the second level of the palace, but yet far too many to suit me and so we continued on upward to the third level, the corridors of which we found almost deserted. Near the mouth of the ramp lay the intersection of two main corridors. Here we hesitated for an instant to reconnoiter. There were people approaching from both directions along the corridor into which we had emerged, but in one direction the transverse corridor seemed deserted and we quickly entered it. It was a very long corridor, apparently extending the full length of the palace. It was flanked at intervals upon both sides by doorways, the doors to some of which were open, while others were closed or ajar. Through some of the open doorways we saw people, while the apartments revealed through others appeared vacant. The location of these we noted carefully as we moved slowly along, carefully observing every detail that might later prove of value to us. We had traversed about two-thirds of this long corridor when a man stepped into it from a doorway a couple of hundred feet ahead of us. He was an officer, apparently a padwar of the guard. He halted in the middle of the corridor as a file of warriors emerged from the same doorway, and, forming in a column of twos, marched in our direction, the officer bringing up the rear.
