us.

I sat up and, clasping my knees with my hands, leaned against the wall. There must be a way out of this for us! All my life I had worked on the theory that if you thought hard enough there was a way out of any difficulty. But this seemed so hopeless! No matter how hard we thought the mad mind of Fraser would always be one jump ahead of us! And maybe we didn't dare even think! If Fraser were able to read minds—as I was nearly sure he was—then hadn't we better keep our minds blank even down here? But an instant's thought showed me the flaw in my logic. Fraser could, without much doubt, read minds—when those minds were close to him. If he could read minds at a distance then he wouldn't need to ask us for information.

But why had he put us here? I burrowed around for the answer. Had he guessed we had outwitted Doctor Semple and not taken the mad serum after all, and was this punishment? No, if Fraser had guessed that he would simply have given us more serum, as he had Brice. Brice! Where was poor Brice now? Was he an idiot, with blank face and shiny, soulless eyes? My mind shuddered away from the thought, taking refuge in my first question: Why were we here? What was Fraser going to do with us?

We lost all track of time. In spite of my winding it my watch stopped and the hours slipped by uncounted. Night came, and another dawn and another night. Twice our roof was lifted and our tiny swinging cell filled with the orange light of the nourishment ray. But we saw no one nor did anyone speak to us. The third day passed in the same isolated silence. Occasionally Foulet or I would utter a monosyllable; the sound of our voices was comforting and the single words would convey little to a listener.

But as the hours of the third night slowly passed the atmosphere in our tiny swinging cell grew tense. Something was going to happen. I could feel it and I knew by Foulet's eyes that he felt it too. The air was tight, electrical. Standing on tiptoe, I glued my eyes to the narrow slit which was our only ventilation. But I could see nothing. The brilliant rosy glow blinded me. I couldn't even see the huge platform floating above our heads.

Then, suddenly, our roof slid back. The magnetic ray was deflected. Above us, in the opening of the trap-door, leered the bright, mad eyes of Fraser.

"Good evening," he said mockingly. "How do you feel?" We smiled hesitantly. Something in his voice made me feel he was addressing us as sane men and not idiots. But why? Weren't we supposed to be idiots when he put us down there?

"You ought to feel all right," Fraser went on critically. "The first dose of that serum lasts only three days. It's cumulative," he added with his professional air. "In the beginning an injection every three days. Then once a week and so on. There's a man who has been with me for three years who needs treatment only once every three months. Well, are you ready to talk?"

So that was it! He had put us down here till the supposed effects of that serum had worn off; and now we were to talk; tell him everything his agents had been risking their lives to find out! We were to sell out our countries to him; betray all the secrets we had sworn by eternity to keep! If we did as he demanded both France and the United States would be at his mercy—and he had no mercy! He was not a man; he was a cruel, power-loving, scientific machine. I clamped my teeth. Never would I talk! I had sworn to protect my country's secrets with my life—and my vow would be kept!

"You will talk?" Fraser asked again, his voice suddenly suave and beseeching. "For those who talk there are—rewards."

"Let down the ladder," said Foulet, in a quiet, conversational tone. "It will be easier to discuss this—"

Fraser's eyes narrowed to gleaming slits. He smiled craftily. "The ladder will be let down—when you talk."

"And if," suggested Foulet, "we don't wish to talk?"

Fraser's lips stretched in a wider grin. His white teeth gleamed. His shiny black eyes glittered. In that warm, rosy light he looked like a demon from hell. He held out his hand. In it shone a long, slender instrument.

"This knife," he said softly, "Will cut the steel cables that connect you to this platform—as if they were cheese! You will talk?" Beside me I heard Foulet gasp. Swiftly my imagination conjured up the picture of our fate. Our determined refusal to divulge the secrets of our respective countries; the severing, one by one, of the four cables holding us to the platform; the listing of our swinging cell; the tipping, the last, terrible plunge two thousand feet. But it would be swift. The power of the magnetic ray would give us no time to think—to suffer. It would be a merciful end....

"Let us up," bargained Foulet. "We will talk." Fraser laughed.

"None of that," he said slyly. "You talk from there and if your information doesn't dove-tail with what I already know—" he flourished the steel knife suggestively.

We were caught! No amount of bluff would save us now. Fraser demanded that truth, facts, actual information—and he wouldn't be fooled by anything spurious. Foulet's shoulder touched mine as we peered up through the roof of our cell at our mad captor. We spoke together:

"There is nothing to say."

The assured smile left Fraser's lips. His eyes glittered red. His whole mad face was contorted with fury. A volley of oaths poured through his twisted mouth. With a gesture of insane rage he pulled the nearest cable to him and slashed it with the knife!

Our cell tilted. Foulet and I were thrown in a heap on the floor. We sprang up to face Fraser again through the roof. His mad eyes glared down at us, soul-chilling, maniacal.

"Talk!" he snarled. "Talk—or I'll slice another!" He drew the second cable to him, holding it in readiness.

I clenched my teeth. Beside me I could see the muscles of Foulet's jaw working. Talk? Never!

"Talk!" screamed Fraser. "Talk!" Our silence and our white faces were his only answer. There was a gleam of the knife in the rosy light. Our cell lurched, quivered, then caught. Would it hold with only two cables? It was hanging on its side. We were standing on what had been the wall. Through the opening in the roof we could see nothing but rosy light and distant stars. How strong were the cables? Could they hold against the pull of the magnetic ray? We could feel the pull now; feel the strain on the cables above us. If Fraser cut the third one—

"Talk!" his voice came, hoarse with fury. "Talk now! You can't see me," he went on; "but I'm pulling the third cable toward me. I'm raising the knife. Will you talk?"

Standing on that quaking wall Foulet and I stared at each other. How long would it be? One second? Half a minute? Thank God it would be quick! This was the worst now. This eternity of waiting.... "I'm cutting it!" yelled Fraser—and with his words the cell lurched, swung, whirled like a spinning top. Foulet and I were tossed around like dried peas in a pod.

Suddenly the thing steadied. Two steel hooks were clamped on the edge of the opening in what had been the roof, and Brice stared at us through the aperture!

"Quick!" he gasped. "There's not a second to lose. Don't stare! Quick, I say. I've got the ladder here. It's steel and it'll hold. Climb up."

Dumbly we obeyed. Our heads were whirling, our bodies bruised and mashed by the shaking up. Blindly, dizzily we climbed up the ladder, scrambled out on the platform. Solid footing again! As Brice loosed the ladder and pulled it up, there was a snap. The last cable had gone! The cell shot down to earth with a speed that must have reduced it to a powder. Foulet and I stared after it, dazed, unbelieving. Brice's whisper hissed in our ears.

"Listen carefully," he gripped our shoulders. "I'm not mad. They shot the stuff into me, but I found an antidote in Semple's office
