"But John—Oh, God, I don't know."
"It's the best way, the surest way. We can't think only of ourselves. If I drove straight out into the desert with it and it blows up within twenty minutes the fallout would still kill several thousand Colonists. The Spaceport's in the other direction, completely isolated. And I can get there in fifteen minutes ... even if I'm stopped by the Wendel police and have to blast my way to it."
"Why should they try to stop you? They'd die themselves—"
"Why did they send someone to trigger that bomb? They'll take any risk now, because they know that Endicott's new bluff could smash them. That cylinder is smaller than the first atomic bomb ever built—much smaller than the one that was dropped on Hiroshima—and if they have to explode a half-dozen of them in different parts of the Colony to demoralize the Colonists and discredit Endicott they're prepared to do it, apparently. Even if it kills thirty thousand people. Or maybe they figured the one I'm taking to the Spaceport—and I am taking it there, Grace—would make the Colonists think twice about taking any more Endicott fuel cylinders home with them."
"You're right, John," Grace Lynton said, with a firmness in her voice which surprised her. "We can't think only of ourselves. Until you come back—every moment will be a living death. But—you must do it. There's no other way."
"I'll be back," Lynton said. "I—I love you, Grace."
"And I love you, John—even though I've said cruel, cutting things at times. I love you very much."
"Take care of yourself, Dad," Thomas said.
"I will, son. Don't worry. Just be the man of the family and keep the kids in line until I get back."
