For the space of a breath we hesitated. To disobey meant certain and instant death at the hands of this soulless maniac. But to obey—to drop through this trap-door—also meant death. I took a step forward. Could we overpower him? But what if we did? There were others here beside Fraser. How many others I had no idea, but surely enough to make things impossible for Foulet and me. Yet we dared not even hesitate. To hesitate implied thinking—and a man robbed of his brain cannot think! There was no way out. Together Foulet and I stepped to the brink of the yawning hole....
For an instant we were almost blinded by a glare of rosy light that seemed to burst upon us from the earth so far below. Here was the source of that strange afterglow! Away beneath us, evidently on the sands of the Arabian desert, glowed four red eyes sending forth the rosy rays that converged at the center of the floating platform. Instantly I comprehended Fraser's scheme. The Fleotite he had invented, and of which the platform and buildings were made, was lighter than air. It followed, therefore, that if it were not anchored in some way it would instantly rise. So Fraser had anchored it with four of his magnetic rays! He had told us that he could regulate the pulling power of the ray, so what he had obviously done was to calculate to a nicety the lift of the Fleotite against the magnetism of the rays.
But instantaneously with this thought came another. Fraser was urging us into the glow of the magnetic ray! If once our bodies came entirely within the ray we would be yanked from the platform and dashed to death—sucked to destruction on the sands below.
In my ear I heard Fraser's fiendish chuckle. "The instinct of fear still holds, eh? My serum can destroy your conscious mind—but not your native fear? Cowards! Fools! But I am not going to push you off. Look!" With his foot he pressed another lever which, while it did not shut off any of the light, seemed to deflect the ray. "Fools!" he said again scornfully. "Go down!"
Then it was I saw where he was sending us! Thirty feet below the platform there swung a small cabin, attached by cables and reached by a swinging steel ladder. As I looked a door in the roof slid back. "Climb down!" ordered Fraser again. There was nothing to do but obey. Accustomed as I was to flying, inured as I had become to great heights, my head reeled and my hands grew icy as I swung myself through that trap door and felt for a footing on the swinging ladder. Suppose Fraser turned the ray back on us as we climbed down? Suppose he cut the ladder? But instantly my good sense told me he would do neither. If he had meant to kill us he could have done it easier than this. No, somewhere in his mad head, he had a reason for sending us down to this swinging cabin.
Five minutes later Foulet and I stared at each other in the cramped confines of our prison. The tiny door in the roof, through which we had dropped, was closed. The steel ladder had been pulled up. We were alone. Alone? Were there no eyes that watched us still, or ears that listened to what we might say? Foulet evidently shared my sense of espionage, for, without even a glance at me, he lay down on the hard floor of our bare little cabin and, to all intents and purposes, fell asleep.
For a few minutes I stood staring at him, then followed his example. As I relaxed I realized I was tremendously weary. The cumulative exhaustion of the past thirty-six hours seemed to crowd upon me with a smothering sense of physical oppression. I looked at my watch and wound it. Five o'clock. Through the narrow slits near the roof of our swinging cell I could see the changing light of dawn, melting in with the rosy glow from the magnetic rays. My eyelids drooped heavily....
When I awoke Foulet was standing near me, his arms folded across his chest, scowling thoughtfully. He nodded as he saw my open eyes, but when I started to speak he shook his head sharply. With his gesture there flooded back to me the feeling that we were watched—even through the walls of our aerial prison and the floor of the platform above us.
