The dim light in the apartment, which was little better than no light at all, I discovered, came from a ventilator in the ceiling and that aside from the shaft that had conducted me to the cell, there was no other opening in the wall or ceiling or floor. The ventilator was about two feet in diameter and led straight up from the center of the ceiling to the roof of the building, several levels above. The lower end of the shaft was about two feet above my finger tips when I extended them high above my head. This avenue of escape, then, was useless, but, alas, how tantalizing. It was maddening to see daylight and an open avenue to the outer world just above me and be unable to reach it. I was glad that the sun had risen, throwing its quick light over the scene, for had I fallen here in utter darkness my plight would have seemed infinitely worse than now, and my first ancestor knew that it was bad enough. I turned my attention now to the chute through which I had descended and I found that I could ascend it quite a little distance, but presently it turned steeply upward and its smoothly polished walls were unscalable.
I returned to the pits. I must escape, but now, as my eyes became accustomed to the dim light, I saw strewn about the floor, that which snatched away my last hope and filled me with horror. Everywhere upon the stone flagging were heaps and mounds of human bones picked clean by gnawing rats. I shuddered as I contemplated the coming of night. How long before my bones, too, would be numbered among the rest?
The thought made me frantic, not for myself but for Tavia. I could not die. I must not die. I must live until I had found her.
Hastily I circled the room, searching for some clue to hope, but I found only rough-hewn stone set in soft mortar.
Soft mortar! With the realization, hope dawned anew. If I could remove a few of these blocks and pile them one on top of the other, I might easily reach the shaft that terminated in the ceiling above my head. Drawing my dagger I fell to work, scraping and scratching at the mortar about one of the stones in the nearest wall. It seemed slow work, but in reality I had loosened the stone in an incredibly short time. The mortar was poor stuff and crumbled away easily. As I drew the block out my first plan faded in the light of what I saw in front of me. Beyond the opening I saw a corridor at the foot of a spiral ramp leading upward, and from somewhere above, daylight was filtering down.
I knew that if I could remove three more of those stones before I was detected I could worm my body through the opening into the corridor beyond, and you may well believe that I worked rapidly.
One by one the blocks were loosened and removed and it was with a feeling of exultation that I slipped through into the corridor. Above me rose a spiral ramp. Where it led, I did not know, but at least it led out of the pits. Cautiously, and yet without any hesitation, I ascended. I must try to reach the laboratory before Phor Tak had slain Tul Axtar. This time I would make sure of the old inventor before I entered the room and I prayed to all my ancestors that I should be in time.
Doors, leading from the ramp to various levels of the palace, were all locked and I was forced to ascend to the roof. As it chanced the wing upon which I found myself was more or less detached, so that at first glance I could see no way whereby I could make my way from it to any of the adjoining roofs.
As I walked around the edge of the building hurriedly, looking for some means of descent to the roof below, I saw something one level below me that instantly charged my attention. It was a man's leg protruding from a window, as though he had thrown one limb across the sill. A moment later I saw an arm emerge, and the top of a man's head and his shoulders were visible as he leaned out. He reached down and up and I saw something appear directly beneath him that had not been there before, and at the same instant I caught a glimpse of a girl, lying a few feet further down, and then I saw the man slide over the sill quickly and drop down and disappear, and all that lay below me was the flagging of a courtyard.
But in that brief instant I knew precisely what I had seen. I had seen Tul Axtar raise the hatch of the Jhama. I had seen Tavia lying bound upon the floor of the ship beneath the hatch. I had seen Tul Axtar enter the interior of the craft and close the hatch above his head.
