"There's only one thing they couldn't get from somebody else," returned Fallon. "Your submarine."
"Yes. The mechanisms are of my own design. They would need me to operate it. Does that mean we are right about the volcano?"
"Maybe. They'd have made plans to control it, of course. Or they may want your ship merely as a model."
There was silence for a while. Outside, heavy wings began to beat again. They came perilously low, went over, and were gone.
Einar Bjarnsson said quietly, "I'm going to take the chance, Fallon. I'm going to try to get my ship through."
"What about the radiations?"
"If Kashimo was planning to use the ship, he'll have arranged for that. Anyway, I'm going to see." His ice-blue eyes stabbed at Fallon. "I can't do it alone."
Joan Daniels said, "I'll go."
Bjarnsson's eyes flicked from one to the other. Fallon's face was dark and almost dangerous.
"Wait a minute," he said gently.
