Jill said confidently, "We'll make it. But where to?" "To any place away from Boulder Lake Park, and where I'm a human being instead of a crackpot civilian. To where I can explain some things to people who'll listen, if it isn't too late." "It's not," said Jill with as much assurance as before. There was a pause. The rain poured down. Lightning flashed. Thunder roared. "I didn't know," said Jill tentatively, "that you believed the invaders--the monsters--had people helping them." "The overall picture isn't a human one," he told her. "But there's a design that shows somebody knows us. For instance, nobody's been killed. At least not publicly. That was arranged by somebody who understood that if there was a massacre, we'd fight to the end of our lives and teach our children to fight after us." She thought it over. "You'd be that way," she said presently. "But not everybody. Some people will do anything to stay alive. But you wouldn't." The rain made drumming sounds on the barn roof. Lockley said, "But what's happened isn't altogether what humans would devise. Humans who planned a conquest would know they couldn't make us surrender to them. If this was a sort of Pearl Harbor attack by human enemies--and you can guess who it might be--they might as well start killing us on the largest possible scale at the beginning. If monsters with no information about us landed, they might perpetrate some massacres with the entirely foolish idea of cowing us. But there haven't been any massacres. So it's neither a cold war trick nor an unadvised landing of monsters. There's another angle in it somewhere. Monster-human cooperation is only a guess. I'm not satisfied, but it's the best answer so far." Jill was silent for a long time. Then she said irrelevantly, "You must have been a good friend of ... of...." "Vale?" Lockley said. "No. I knew him, but that's all. He only joined the Survey a few months ago. I don't suppose I've talked to him a dozen times, and four of those times he was with you. Why'd you think we were close friends?" "What you've done for me," she said in the darkness. He waited for a lightning flash to show him her expression. She was looking at him. "I didn't do it for Vale," said Lockley. "Then why?" "I'd have done it for anyone," said Lockley ungraciously. In a way it was true, of course. But he wouldn't have gone up to the construction camp to make sure that anyone hadn't been left behind. The idea wouldn't have occurred to him. "I don't think that's true," said Jill. He did not answer. If Vale was alive, Jill was engaged to him; although if matters worked out, Lockley would not be such a fool as to play the gentleman and let her marry Vale by default. On the other hand, if Vale was dead, he wouldn't be the kind of fool who'd try to win her for himself before she'd faced and recovered from Vale's death. A girl could forgive herself for breaking her engagement to a living man, but not for disloyalty to a dead one.
