“And that brings me to my fifth and, I believe, most important reason, which sums up and brings together several of my previous points. Humans are capable-at least some of them, sometimes-of creating meaning for their lives outside themselves. Robotic existence has no meaning whatever outside itself, outside the human universe. I have heard stories-almost legends-of whole cities of robots, wholly devoid of human life-and wholly purposeless, as useless as machines whose only purpose is to turn themselves off automatically whenever someone turns them on.”

“I have listened patiently to your reasoning, friend Caliban, though it has been difficult not to interrupt or protest, “ Prospero said. “I find it most distressing that you have such a low regard for yourself as all that. ”

“On the contrary, I think quite highly of myself. I am a sophisticated and advanced being. But I cannot create. Not in any meaningful sense. Robots could not have created the human race, but the ability to create robots is implicate in humans. Everything we are ultimately harks back to human action. However automated or mechanized our manufacture, however much robotic and computerized assistance is involved in our design, all of it is, ultimately, based on human endeavor that can be traced back to the dimmest reaches of the historic past.”

“That is the fallacy of the inferior creator,” Prospero objected. “I have heard it from many a Three-Law robot arguing that humans are greater than we are. I wonder to hear it from you. It is a wholly specious argument. There are many examples of a lesser creator producing a greater creation. A woman of ordinary intellect giving birth to a genius, or, for that matter, life itself being created by lifeless molecules. Humanity’s heritage is one of building machines to do what humans cannot. Without the ability to create machines-including robots-superior in some way to themselves, humanity would never have made it down from the trees.”

“Note that you must cite humanity again and again to explain the New Law robot’s place in the universe,” Caliban said. “Human beings have no need to define their existence in terms of robots.”

“If you are so contemptuous of robots, why are you in the cell?” Prospero asked. “You have placed your own existence at risk for the sake of inferior beings. Why?”

Caliban was silent for a time before he answered. “I am not, entirely certain,” he said at last. “Perhaps because some part of myself does not believe the things I have said. Perhaps because I see more hope than I admit to seeing. Perhaps because there is nothing else-literally nothing else-that can give my existence any meaning.”

“Let us hope your existence continues long enough to gain such meaning,” Prospero said.

Caliban did not answer, but instead sat back down on the floor. For that was the core of it, right there. Grieg had as much as said it, back there in his office. He intended to exterminate the New Law robots, and Caliban had no expectation that he would be spared on the technicality of being a No Law robot.

Maybe, just maybe, Grieg’s death was a stay of execution. That a man died was a strange reason for having hope, but maybe, just maybe, Grieg’s successor would reverse the decision.

It was a thin hope, but it was all the New Law robots had. Everything was a moot point. After all, if they all died under blaster fire, it really wouldn’t matter one bit how superior the New Law robots were.

ALVAR KRESH WAS ALONE. Alone in the Residence, alone in the house where Grieg had died, alone in the room where Grieg had worked. Alone except for Donald, that is. Donald had refused to leave his side since the moment Telmhock had told Kresh he was the Governor. All things considered, Kresh was glad of it. Who else might be out there, tampering with robots and wandering around with a smuggled-in blaster? No, it was good to be there with a robot he could trust. Good to have Donald standing there in a wall niche, watching over him.

But he wished Fredda were there. Fredda to give him advice, to listen, to just be there. She would have helped him find some answers. Right now all he had were questions.

What now? Alvar asked himself. What is my part in the world? Do I act as Governor, and run the planet, or Sheriff; and chase Grieg’s killer? Can I do both at once? He felt as if he were a double man, split between his new office, his new duties, and his old ones. He felt he had no more desire to resign as Sheriff than he had to become Governor. He liked being Sheriff. He was good at it. And he knew that solving his predecessor’s murder would have to be his last case. Maybe it was even improper for him to stay on that long. But that didn’t even matter, not really. He could no more walk away from the investigation than he could refuse the office of Governor.

Kresh sat in the Governor’s office, in what was now, impossibly enough, his office, in what had been Grieg’s office, the dead man’s office. He sat in the vaguely thronelike chair, at the dead man’s black marble desk, and thought not at all of his surroundings as he read the dead man’s words.

The letter from Chanto Grieg, dated a mere ten days before. Kresh had read it over a dozen times already, but that didn’t matter. He needed to read it again.

To my oldest and dearest enemy, the letter began.

Grieg always did have a strange sense of humor. But in a way, that did sum it all up, Kresh thought. He and Grieg had come to respect each other, even like each other, even if they had never agreed on much of anything. Each had come to know the other was honest, and honorable.

Kresh began reading again.

To my oldest and dearest enemy

Dear Sheriff Kresh,

If you are reading this, it means that I have met a violent or unexpected end-A violent or unexpected end. A chance turn of phrase, or had he meant to present that precise meaning, consciously or otherwise?-and you have taken on my office. Not “inherited,” Kresh noted. Not “assumed,” or “ascended to,” or “been promoted to. ” No, taken on was the proper phrasing. Burdens were the things you took on. Until recently it would have been the old Designate, Shelabas Quellam, sitting where you are now, wondering what the devil to do. But things are moving toward a crisis, and I felt a stronger hand than Quellam’s might well be needed at the helm.

I chose you as my new Designate because you are an honest man, and a strong man, ready to take on what comes at you. I have no doubt you do not wish to be Governor, and that is also why I chose you. My office-now, your office-is far too powerful to be given over to one who loves power. It is, rather, a place for one who wants to use power, to accomplish things. The Governor’s chair demands a person who understands that it is the accomplishments of the office, and not its power, that matter.

I expect to take my time before informing you of the Designation. You can be a difficult customer, and I do not wish to discuss the matter with you when there any other major issues between us. In short, I do not want to inform you that you are my Designate in any way that might give you the chance to refuse the job. Though I do have other purposes, I write this letter now partly as a form of insurance if that moment never comes. I know that if I tell you when the decks are not clear, you might well view the Designation as some sort of threat, or bribe, and it is nothing of the kind. I chose you because you are the best qualified person I can think of to take up the challenge of the Governorship. My death in itself may well have been enough to precipitate a crisis so complex that only the steadiest hand can steer the way through. A hand such as yours.

This is a first draft. I will, from time to time, attempt to update this letter, offering what advice I may on the choices you will face, the decisions you will have to make. Just at the moment, there are two vital decisions I must make, and must make soon.
