Rapidly my strength came back to me, though the strange food supplied us once a day by our captors was almost uneatable. But as the days fled by, my spirits sank lower and lower, and less and less we spoke to each other as the doom of our sun approached, the only change in any thing around us being the moment each twenty-four hours when the signal-horns called across the city, summoning the hordes in its streets to their four-hour sleep-period. At last, though, we woke suddenly to realization of the fact that nine days had passed since my awakening, and that upon the next day the dark star would be plunging past the burning yellow star above us and jerking it into its grip. Then, at last, all our apathy dropped from us, and we raged against the walls of our cells with insensate fury. And then, with startling abruptness, came the means of our deliverance.
For hours there had been a busy clanging of tools and machines somewhere in the great building above us, and numbers of the tentacle-creatures had been passing our barred door carrying tools and instruments toward some work being carried out overhead. We had come to pay but little attention to them, in time, but as one passed there came a sudden rattle and clang from outside, and turning to the door we saw that one of the passing creatures had dropped a thick coil of slender metal chain upon the floor and had passed on without noticing his loss.
In an instant we were at the door and reaching through its bars toward the coil, but through we each strained our arms in turn toward it the thing lay a few tantalizing inches beyond our grasp. A moment we surveyed it, baffled, fearing the return at any moment of the creature who had dropped it, and then Dal Nara, with a sudden inspiration, lay flat upon the floor, thrusting her leg out through the grating. In a moment she had caught the coil with her foot, and in another moment we had it inside examining it.
We found that though it was as slender as my smallest finger the chain was of incredible strength, and when we roughly estimated the extent of its thick-coiled length we discovered that it would be more than long enough to reach from our window to the street below. At once, therefore, we secreted the thing in a corner of the room and impatiently awaited the sleep-period, when we could work without fear of interruption.
At last, after what seemed measureless hours of waiting, the great horns blared forth across the city outside, and swiftly its streets emptied, the sounds in our building quieting until all was silence, except for the humming of a few watchful cones above the great condenser, and the deep droning of the condenser itself in the distance. At once we set to work at the bars of our window.
Frantically we chipped at the rock at the base of one of the metal bars, using the few odd bits of metal at our command, but at the end of two hours had done no more than scratch away a bare inch of the glowing stone. Another hour and we had laid bare from the rock the lower end of the bar, but now we knew that within minutes the sleep-period of the city outside would be ending, and into the streets would be swarming its gliding throngs, making impossible all attempts at escape. Furiously we worked, dripping now with sweat, until at last when our time-dials showed that less than half an hour remained to us I gave over the chipping at the rock and wrapped our chain firmly around the lower end of the bar we had loosened. Then stepping back into the cell and bracing ourselves against the wall below the window, we pulled backward with all our strength.
A tense moment we strained thus, the thick bar holding fast, and then abruptly it gave and fell from its socket in the wall to the floor, with a loud, ringing clang. We lay in a heap on the floor, panting and listening for any sound of alarm, then rose and swiftly fastened the chain's end to one of the remaining bars. The chain itself we dropped out of the window, watching it uncoil its length down the mighty building's glowing side until its end trailed on the empty glowing street far below. At once I motioned Hurus Hol to the window, and in a moment he had squeezed through its bars and was sliding slowly down the chain, hand under hand. Before he was ten feet down Dal Nara was out and creeping downward likewise, and then I too squeezed through the window and followed them, downward, the three of us crawling down the chain along the huge building's steeply sloping side like three flies.
I was ten feet down from the window, now, twenty feet, and glanced down toward the glowing, empty street, five hundred feet below, and seeming five thousand. Then, at a sudden sound from above me, I looked sharply up, and as I did so the most sickening sensation of fear I had ever experienced swept over me. For at the window we had just left, twenty feet above me, one of the tentacle-creatures was leaning out, brought to our cell, I doubted not, by the metal bar's ringing fall, his white, red-rimmed eye turned full upon me.
I heard sighs of horror from my two companions beneath me, and for a single moment we hung motionless along the chain's length, swinging along the huge pyramid's glowing side at a height of hundreds of feet above the shining streets below. Then the creature raised one of its tentacles, a metal tool in its grasp, which he brought down in a sharp blow on the chain at the window's edge. Again he repeated the blow, and again.
He was cutting the chain!

For a space of seconds I hung motionless there, and then as the tool in the grasp of the creature above came down on the chain in another sharp blow the sound galvanized me into sudden action.
"Slide on down!" I cried. They didn't, however, but followed me up the chain, though Dal Nara and I alone came to grips with the horrible dead-star creature. I gripped the links with frantic hands, pulling myself upward toward the window and the creature at the window, twenty feet above me.
Three times the tool in his hand came down upon the chain while I struggled up toward him, and each time I expected the strand to sever and send us down to death, but the hard metal withstood the blows for the moment, and before he could strike at it again I was up to the level of the window and reaching up toward him.
As I did so, swift black tentacles thrust out and gripped Dal Nara and me, while another of the snaky arms swept up with the tool in its grasp for a blow on my head. Before it could fall, though, I had reached out with my right hand, holding to the chain with my left, and had grasped the body of the thing inside the window, pulling him outside before he had time to resist. As I did so my own hold slipped a little, so that we hung a few feet below the window, both clinging to the slender chain and both striking futilely at each other, he with the metal tool and I with my clenched fist.
A moment we hung there, swaying hundreds of feet above the luminous stone street, and then the creature's tentacle coiled swiftly around my neck, tightening, choking me.
Hanging precariously to our slender strand with one hand I struck out blindly with the other, but felt consciousness leaving me as that remorseless grip tightened. Then with a last effort I gripped the chain firmly with both hands, doubled my feet under me, and kicked out with all my strength. The kick caught the cone-body of my opponent squarely, tearing him loose from his own hold on the chain, and then there was a sudden wrench at my neck and I was free of him, while beneath Dal Nara and I glimpsed his dark body whirling down toward the street below, twisting and turning in its fall along the building's slanting side and then crashing finally down upon the smooth, shining street below, where it lay a black little huddled mass.
Hanging there I looked down, panting, and saw that Hurus Hol had reached the chain's bottom and was standing in the empty street, awaiting us. Glancing up I saw that the blows of the creature I had fought had half severed one of the links above me, but there was no time to readjust it; so with a prayer that it might hold a few moments longer Dal Nara and I began our slipping, sliding progress downward.
