"We will apply the same principle," said Kingston. "One brings two and each brings two more. My men on Earth One will assemble the four subcritical masses tomorrow for instructions," said Kingston. "This is the one weak link. But once we start, we can move the stuff like fury."

"What do you fear?" asked Maddox.

"Bronson! He has your laboratory. Complete. He is well hidden somewhere and, until we can locate him, we are treading on dangerous ground. For I know that he is keeping an eye on everything we do. And until we locate him we can do nothing."

"Why doesn't he do something, then?"

Kingston laughed bitterly. "Probably because he doesn't quite know what to do."

Maddox grinned. "Also because you've got the key to Earth One. And," he said grimly, "it might be that he has been ignorant until just now when you've shown him how to fight this war."

Kingston whitened in fear. He shook his fist at the flaming horror on the viewer plate and said, "I wish Bronson were in that!"


Virginia Carlson reeled back from the viewer with a cry. Bronson left his work and came to stand beside her.

"What?" he asked.
