“He pretends to be open-minded and skeptical, but it’s clear that he would never have spent so much time and effort in this field unless he had some subconscious faith. I challenged him on this and he admitted that I was probably right. He would like to find some convincing proof. That is why he Is always carrying out these experiments, even though he pretends that they are only games.”

“You are sure he doesn’t suspect that your interest is more than academic?”

“Quite sure. In many ways Boyce is remarkably obtuse and simple-minded. That makes his attempts to do research in this, of all fields, rather pathetic. There is no need to take any special action regarding him.”

“I see. And what about the girl who fainted?”

“This is the most exciting feature of the entire affair. Jean Morrel was, almost certainly, the channel through which the information came. But she is twenty-six — far too old to be a prime contact herself, judging by all our previous experience. It must, therefore, be someone closely linked to her. The conclusion is obvious. We cannot have many more years to wait. We must transfer her to Category Purple: she may be the most important human being alive.”

“I will do that. And what of the young man who asked the question? Was it random curiosity, or did he have some other motive?”

“It was chance that brought him there — his sister has just married Rupert Boyce. He had never met any of the other guests before. I am sure the question was unpremeditated, being inspired by the unusual conditions — and probably by my presence. Given these factors, it is hardly surprising that he acted in the way he did. His great interest is astronautics: he is secretary of the space-travel group at Cape Town University, and obviously intends to make this field his life study.”

“His career should be interesting. Meanwhile, what action do you think he will take, and what shall we do about him?”

“He will undoubtedly make some checks as soon as he can. But there is no way in which he can prove the accuracy of his information, and because of its peculiar origin he is hardly likely to publish it. Even if he does, will it affect matters in the slightest?”

“I will have both situations evaluated,” Karellen replied. “Though it is part of our Directive not to reveal our base, there is no way in which the information could be used against us.”
