I did not again try to sleep. I did not feel like sleeping; instead I remained at the controls and watched the desolate landscape as it rushed forward to pass beneath me. With the coming of dawn I saw Tjanath directly ahead of me and as I approached the city it was difficult for me to realize that I could do so with utter impunity and that my ship with its closed ports was entirely invisible. Moving slowly now, I circled above the palace of Haj Osis. Those portions of the palace that were topped by flat roofs revealed sleepy guardsmen. At the main hangar a single guardsman watched. I floated above the east tower; beneath me, cuddled in her sleeping silks and furs, I could picture Tavia. How surprised she would be could she know that I hovered thus close above her. Dropping lower I circled the tower, coming to a stop finally opposite the windows of the room in which Tavia had been confined. I maneuvered the ship to bring one of the ports opposite the window and close enough to give me a view of the interior of the room. But though I remained there for some time, I could see no one and at last I became convinced that Tavia had been removed to other quarters. I was disappointed for this must necessarily greatly complicate my plans for rescue. I had foreseen but little difficulty in transferring Tavia by night through the tower window to the flier; now I must make my plans all anew. Everything hinged, of course, upon my ability to locate Tavia. To do that it was evident that I must enter the palace. The moment that I quitted the invisibility of my flier, I should be menaced by the greatest danger at every turn, and, clothed as I was in home-made harness fashioned by the hands of the slaves of Phor Tak, I should arouse the active suspicion of the first person who laid eyes upon me. I must enter the palace and to do it in any degree of safety I must have a disguise. All my ports were now closed, the periscope being my only eye. I turned it slowly about as I tried to plan some method of procedure that might have within it some tiny seed of success. As the panorama slowly unfolded itself upon the ground glass before me there appeared the main palace hangar and the single warrior upon watch. Here my periscope came to rest, for here was an entrance to the palace and here a disguise. Slowly maneuvering my ship in the direction of the hangar, I brought it down upon the roof of that structure. I should have been glad to moor it, but here there were no means at hand. I must depend upon its own weight and hope that no high wind would rise.
