Mallory said, "It really doesn't matter whether he heard us or not, O'Shea. What I was about to say is, there lies beyond that door a weapon potent enough to end the war immediately—but it must never be used. For once loosed to the winds, those abominable spores would not only end this war, they would still all animal life on the face of Earth. I have said they were self-propagating. Each new generation of spores would deepen the slumber into which mankind had been soothed by the first—"

I said, "But why keep them, Doctor?"

"I don't quite know, O'Shea. Perhaps I have done so because I am, at heart, more emotional than a true scientist should be. Perhaps I have a secret fear that there may come a day when I shall be forced to play God, give mankind its release from the chains of the tyrant."

Maureen shuddered.

"No, Doctor! You mustn't even think of that. Things look black now, but they can't go on like this forever. Right and truth and liberty will prevail in the end. There must be some other way to escape—"

"There is," said Dr. Mallory quietly. "There is another way. A plan I have been working on ever since the failure of my first. There is one last refuge to which they cannot follow us."

I said, "I don't understand, Doctor. Do you mean Antarctica?"

His grave eyes captured, held mine.

"No," he said. "A place more remote than even that. I mean, O'Shea—the moon!"
