"Well, as a matter of fact," fabricated Dan, "the Super-Detectonic rays are a bit slow in getting into operation. But you can't expect miracles. If you'll give me a little more time—a few more days, maybe a week—I'll promise you results."

A cold sweat had broken out all over him before he had explained, in scientific detail, just why he might succeed if given another week. Thank God! they had not suspected! Or had they suspected?—and were they only toying with him? In any case, they had, wittingly or unwittingly, broken into his experiment at the crucial point. Would he ever again catch the interrupted message?

His fingers shaking with eagerness, he turned back to the radio. But even as he did so, the sneer on Wiley's retreating face hit him like a taunt.


After the first cruel shock, Lucile had realized just what was behind Dan's disappearance. She not only was sure that he had been kidnapped by Hogarth and his gang, but that any effort on her part to report to the police would result in her own immediate apprehension. Already her position was perilous—might the conspirators not finish the job by seizing her at any moment? There was nothing to be done, therefore, except to change her residence, without informing anyone where she was going. Then, in secret, she might plan to free her husband.

At first, however, no tenable idea came to her. Meanwhile, through her old professors at Merlin University, where she had been an excellent student, she obtained access to the chemical laboratory, and experimented day and night for means to increase the power of telurox. If it were possible to divert to the earth enough of the gravity that shot past it into space, might the planet not even now be drawn back to its orbit?

For weeks she labored, without results. She was merely one more discouraged person in a discouraged world, when at length a startling incident occurred. She had gone out for a hasty bite of lunch, and on her return she noticed that her assistant, young Dick Harson, was listening to the radio, as he often did, while munching at a sandwich.

"Well, anything new?" she asked, with a faint smile.

"Nothing but a crazy noise, like a telegrapher breaking in on the broadcast," he answered. "If it's still on, I'll show you."

He switched the dial. "There it is!" he exclaimed, after a moment. "Doesn't it sound just like a secret code?"
