“Of all the problems that faced us when we came to Earth, this was the most difficult,” admitted Karellen. “You have trusted our wisdom in other matters — surely you can trust us in this!”

“I trust you,” said Stormgren, “but Wainwright doesn’t, nor do his supporters. Can you really blame them if they put a bad interpretation on your unwillingness to show yourselves?”

There was silence for a moment. Then Stormgren heard that faint sound (was it a crackling?) that might have been caused by the Supervisor moving his body slightly.

“You know why Wainwright and his type fear me, don’t you?” asked Karellen. His voice was sombre now, like a great organ rolling its notes from a high cathedral nave. “You will find men like him in all the world’s religions. They know that we represent reason and science, and however confident they may be in their beliefs, they fear that we will overthrow their gods.

Not necessarily through any deliberate act, but in a subtler fashion. Science can destroy religion by ignoring it as well as by disproving its tenets. No one ever demonstrated, so far as I am aware, the non-existence of Zeus or Thor — but they have few followers now. The Wainwrights fear, too, that we know the truth about the origins of their faiths. How long, they wonder, have we been observing humanity? Have we watched Mohammed begin the Hegira, or Moses giving the Jews their laws? Do we know all that is false in the stories they believe?”

“And do you?” whispered Stormgren, half to himself.

“That, Rikki, is the fear that torments them, even though they will never admit it openly. Believe me, it gives us no pleasure to destroy men’s faiths, but all the world’s religions cannot be right — and they know it. Sooner or later man has to learn the truth; but that time is not yet. As for our secrecy, which you are correct in saying aggravates our problems — that is a matter beyond our control. I regret the need for this concealment as much as you do, but the reasons are sufficient. However, I will try and get a statement from my — superiors — which may satisfy you and perhaps placate the Freedom League. Now, please, can we return to the agenda and start recording again?”

“Well?” asked van Ryberg anxiously. “Did you have any luck?”

“I don’t know,” Stormgren replied wearily as he threw the files down on his desk and collapsed into the seat. “Karellen’s consulting his superiors now, whoever or whatever they may be. He won’t make any promises.”

“Listen,” said Pieter abruptly, “I’ve just thought of something. What reason have we for believing that there is anyone beyond Karellen? Suppose all the Overlords, as we’ve christened them, are right here on Earth in these ships of theirs? They may have nowhere else to go, but they’re hiding the fact from us.”
