He shook his head. "I arrived from my bedroom on Earth Three—the same room but a nursery in Three's time trail."
"I saw the same room from half-transfer," she said, "and there was that pillar of atomic fire in the sky."
Bronson blinked.
"So," he said with an explosive exhale of breath. "So the fission-train in the earth will work on Earth Three as well as Two."
"What do you mean?" asked the girl.
"Kingston undoubtedly intends to transfer bits of the earth-fire from Two to One and thus destroy both of them. That was a test. They brought it, noted its performance on Three and then carefully shipped the thing back again."
Virginia snorted angrily. "I'd like to ship the entire Alamogordo Fire to Earth Three and let Kingston and Maddox roast!"
Bronson nodded. "But the thing that strikes me the hardest is that only for that very instant of blast was there the chance for time-fission. Then all three worlds have the same phenomena and the same effects. One might think that Three would remain a place where no fission-explosion could take place while on Two all atomic releases of power start the endless fission in the earth."
"But does that help us any?"
