said Fredda.
The jet-black robot regarded first Fredda, and then Caliban. "Very well," he said. "We will depart. But I doubt that I will be the first or last robot to observe that the more I know about humans, the less I understand them."
Fredda Leving sighed wearily. There were times when it was frustrating in the extreme listening to Three-Law robots holding forth on the subject of human behavior. Prospero and the other New Laws were even worse. At least Three-Law robots were not judgmental. Prospero had an opinion about everything.
Fredda could almost imagine him as the last priest of some long-forgotten human religion, always ready to debate any intricate point of theology, so long as it was of no interest or importance to anyone at all. There were times Caliban was no better. She had designed and built both of these robots by herself. Surely she could have designed their brains so they didn't spend their days logic-chopping. But it was too late now. "Whatever you think of my reasons for doing so," she said, "I must ask you again to leave, by the back way. Our next appointment is in three days, is it not?"
"Yes," said Prospero. "We have several other appointments that will take up the intervening time."
"Fine then. Return in three days, in the afternoon, and we will conclude our business."
Caliban nodded his head toward her, in what was almost a bow. "Very well," he said in a most courteous tone. "We will see you at that time."
Prospero took no interest in courtesy. He simply turned, opened the door, and left the room, leaving all the farewells to his companion. Caliban had to hurry just to keep up with him.
Fredda watched them go, and found herself once again wondering about Prospero. She did not understand what went on behind those glowing eyes. There was something not quite right about a robot that-that secretive. She shook her head as she crossed the room. Not much point in worrying about it now. She sealed the door shut behind them and scrambled the keypad. Only she and Caliban and Prospero knew the door's keypad combination.
And there were times she thought seriously about taking at least one name off that list.

CALIBAN FOLLOWED PROSPERO down the tunnel. It ran for about a hundred meters, and deposited them at the base of a ravine that was otherwise quite inaccessible to the house. Their aircar was hidden there.
"I would like to know what all that was about," Caliban said as they emerged from the tunnel into the cool of the evening.
"I spoke the truth," Prospero said coolly. "It was in part merely a test to see how she would react to such an accusation. Surely you would agree it is worth knowing if she is capable of betraying us. " Prospero climbed into the pilot's station.
Caliban followed, climbing into the forward passenger seat. "I suppose the case could be made that such information would be useful in a general sense," he said. "But you have dealt with Dr. Leving for quite some time now. Why worry about such hypotheticals now? And if the need for a test was only part of your intent, what was the rest?"
"I have answers to both questions, friend Caliban, but I do not choose to give them now. This is all I can tell you: I believe we are in danger. The possibility that we will be betrayed-or have been already-is quite real. And I can tell you no more than that."
Prospero engaged the aircar's controls, and they lifted off into the evening air. Caliban said no more, but he found that he had reached a conclusion about Prospero. There was no longer the slightest doubt in his mind that the New Law robot was unstable. He did not merely suspect betrayal on all sides-he virtually invited it. He had gone out of his way to encourage Dr. Leving's hostility. More than likely, the fellow was confusing danger to himself with danger to the New Laws.
All of which made Caliban's next decision quite simple. As soon as it was conveniently possible, he would put some distance, in every sense of the word, between himself and Prospero.
He no longer wished to stand quite so close to so tempting a target.
FREDDA LEVING WALKED to the other end of the underground safe room, and went through the open door there. She wearily closed the door behind her, and scrambled the combination as well. She, Fredda, was the only one who knew
