Utopia

There was no logical reason why Caliban should have cared about Three-Law robots. There were few among them that felt he had any right to existence. But even so, it was good to see some of them would be spared such meaningless demises. Caliban had seen more than enough useless death.

The aircar flew south, to Valhalla.

And high overhead, the comet grew brighter in the sky.

ALVAR KRESH REMAINED alone in the office, alone with Unit Dee. There was very little one of them could say to the other-but Kresh could think of no more useful place for him to be. There was nothing else that could be done. All he could do was sit here and hold Unit Dee’s wholly imaginary hand and hope that she would

“Excuse me, Governor Kresh?”

“Yes, Dee. I am here. What is it?”

“There is a new development. There is a repeating broadcast being made over a general-purpose hyperwave frequency reserved for robot use. The broadcast is originating from an aircar flying at speed through the projected impact zone of the first fragment. I would ask you to listen to it.”

A new voice, one Kresh knew only too well, came in over the headphones. “This is Caliban, robot CBN-001,” it began.

Kresh listened intently to the message twice through, more and more astonished with every moment. What the devil was Caliban up to? Why did he think he could find Beddle when no one else could? How had he gotten into the air over the impact zone?

“Have you heard enough of it, Governor Kresh?” Dee asked.

“What? What? Yes, yes, of course.”

“According to my information,” said Dee, “Caliban is a No Law robot, with no restrictions on his behavior. He is capable of lying, stealing, cheating, and murder-just like a human. Is that correct?”

“In essence yes. Just like a human, there are no restrictions on his behavior save those he puts on himself.”

“I wonder how much such restrictions could be worth,” Dee said, a distinct note of disdain in her voice. “Very well. It seems that Caliban believes he can save Simcor Beddle before the impact. Answer honestly, on your honor. Do you believe him?”

Only the truth can save us, Kresh told himself. Only the truth. He thought-or at least he hoped-he knew what was going through Dee’s mind. If Caliban were indeed able to save Beddle, then the First Law requirement for Dee to protect Beddle would be diminished. Diminish it enough, and maybe-just maybe-it would allow Dee to act, allow her to perform the intended terminal descent package. Or had he figured it wrong? Would it somehow induce her to initiate Last Ditch? Or was the danger to Beddle some sort of crutch, a shield that Dee was using to save herself from having to make an impossible choice? There was no way to know.

Suppose he told her what he thought she wanted to hear, and it had the wrong effect on her? Supposing he lied to her-and then Caliban broadcast again, saying something that showed Kresh to be a liar?

No. There was no way to know the outcome, no matter what he said. The truth, then. If the planet was to live or die based on his next words, then let those words be the truth.

But what the devil was the truth? Did Caliban mean what he said? And was Caliban judging the situation properly? Or was Caliban trying, in some mad way, to save the world by lying?

Kresh knew that Caliban could lie-but would he? Was he? Kresh had no idea was Caliban was up to, what his motives were.

“Governor Kresh? I must have your answer.”

“Yes, of course Unit Dee. But I must consider carefully.”

“Very wise, sir, I am sure, but time is short.”

As if he had to be told that. “Just a moment more,” said Kresh. He wished he knew why, exactly, Unit Dee needed to know about this one event at this one time.

He wished Fredda were here, all her expertise at the ready, guiding him through all the intricacies of it. But Unit Dee had wanted Kresh alone. He dared not break that agreement now, even for Fredda’s sage advice

But wait a second. Fredda. Caliban had invoked Fredda’s name and honor. That was his answer. That was it. Alvar Kresh had never entirely made up his mind about Caliban. From Kresh’s perspective, the No Law robot had been so many things-fugitive, victim, hero, villain, schemer, a voice for decency, a voice for rebellion. But somehow, underneath it all, always there had been a bedrock of integrity. Caliban had no external laws imposed upon him-but he had always kept faith with the laws he had made for himself.

And he had always treated Dr. Fredda Leving, his patron, his creator, with the greatest deference and respect. Caliban had always done her honor.

He would not put all that on the line lightly. Caliban would not lie in the creator’s name.

“Caliban is to be trusted,” he said at last. “He means what he says, and he can do what he believes he can do.”

“Thank you, Governor. I believe you, and believe you are correct. Please stand by.”

There was a brief pause, and then the unison voice, Unit Dee and Unit Dum together, spoke together once again.
