“One thing I can tell you your evacuation experts might not have told you,” said Fredda. “Make sure it’s a total evacuation, and that you can prove it’s total. Leave one person there-or even leave open the possibility that one person is out there-and you’re going to be knee-deep in overstressed Three-Law robots trying to pull off a rescue.”

“I’m not going to worry about losing a few robots in comparison to saving the whole planet.”

“No, of course not,” Fredda said. But she thought of Kaelor’s death a few hours before, and could not help but wonder if she would be quite as careless about the lives of robots in the future. “But those robots could cause a great deal of trouble. Even if you can prove there’s no one left in all of Utopia, a lot of robots are going to feel strong First Law pressure to stop the comet impact, any way they can. After all, the comet sure as hell represents danger to humans. More than likely, someone is going to die in a building collapse or an aircar caught by the shockwave, or whatever.”

“Maybe so, but how could the robots stop it?” Kresh asked.

“For starters, is that an all-human crew on the spaceside team? You have to assume that any robots on that job will do their best to sabotage the job. Even a low-function fetch-and-carry robot will have enough capacity to realize that an incoming comet represents danger.”

“Burning devils,” said Kresh. “I hadn’t thought of that. I hope someone else has, but we’ve got to damn well make sure the crews on those ships are all human. Donald, pass that order and explain-” Alvar stopped and looked at Donald. “No, wait a minute,” he said. “I can’t use you to pass the order for the same reason. Your First Law means you won’t cooperate either.”

“On the contrary, sir. I am able to pass the message.”

Fredda looked at Donald in surprise. “But don’t you feel any First Law conflict?” she asked.

“A certain amount of it, Dr. Leving, but as you well know, a properly designed Three Law robot feels some First Law stress most of the time. Virtually every circumstance includes some danger, if only low-probability-danger, for a human. A human could drown swallowing a glass of water, or catch a deadly plague by shaking hands with an off-planet visitor. Such dangers are not enough to force a robot to action, but are enough to make the First Law felt. There is some potential danger here, yes, but you designed me as a police robot, and I am equipped to deal with more risk than most robots.”

“I see,” said Kresh, keeping his voice very steady. Fredda had the very strong impression that she was going to have to ask him about all this in the very near future. “But, meaning no offense,” said Kresh, “I think it might be best if I took care of that order myself. I’ll call the spaceside planning group, banning all robots from the operation, and explaining why.”

“No offense taken, sir. You must take into account the possibility that I am deceiving you. I can imagine a scenario where I would disobey that order, and see to it that as many robots as possible went into the spaceside operation in order to sabotage it.”

Kresh gave Donald a quizzical look. “My imagination works a lot like yours,” he said. He turned to Fredda. “Donald’s good example to the contrary,” he said, “I don’t think I’ve ever been in a situation where robots have done so much to make my job difficult. To make everyone’s job difficult.”

“That’s what you get when you try and take risks, even necessary risks, around robots,” Fredda said. “I think the real story is that none of us have ever really tried to take risks before.”

“And robots don’t like risks,” said Kresh. “They’re going to keep us all so safe they’re going to get us all killed. Sooner or later we’re going to have to-”

“Excuse me, Governor,” said Donald. “The Residence security system has alerted me via hyperwave that an aircar is landing in the visitor’s parking area.”

“Who the devil has found me here?” Kresh muttered.

“It could just be some tourist who wants to get a look at the Winter Residence,” Fredda said.

“Not with our luck,” he said, getting up. He crossed the room and sat down at the comm center. He punched in the proper commands, and brought up the view from the main entrance security cameras. There was the car, all right. And someone getting out. Kresh zoomed in on the figure, pulled in to a tight head-and-shoulders shot, and set the system to track the shot automatically. It was a man, his back to the camera as he climbed out of his armored long-range aircar. He turned around, and looked straight toward the concealed surveillance camera, as if he knew exactly where it was. He smiled and waved…

“What the devil is he doing here?” Kresh muttered to himself.

“Who is it?” Fredda asked, coming up to stand behind her husband.

“Gildern,” said Kresh. “Jadelo Gildern. The Ironhead chief of security.” He frowned at the image on the screen. “He’s no tourist come to get a look at the place. He knows we’re here. I think you’d better go let him in, Donald. Bring him to the library. We’ll wait for him there.”

“Yes sir,” said Donald.

“What does he want?” Fredda asked. “Why is he here?”

Kresh shut off the comm system and stood up. “From what I know of Gildern, there’s only one thing he ever wants,” he said. “What he wants is a better deal for Jadelo Gildern.”

“GOOD EVENING. MASTER Gildern,” said the short blue robot who met him at the door. “The Governor has ordered me to escort you to him.”

Gildern nodded curtly. Others might waste their time in courtesy to robots, but Ironheads did not. Besides, he had other things on his mind. It would be best for all concerned if this interview went very quickly indeed. There were unquestionably risks in the game he was playing, and he saw no benefit at all in making those risks greater. The blue robot. Donald 111. That was its name. Built by Leving herself, and Kresh’s personal assistant since he was sheriff. Deliberately designed to seem unthreatening. Frequently underestimated. Gildern smiled to himself. He often found it calming to remember just how much he had in his dossiers.

The robot led them through a large central court and down a corridor leading off to the right, then stopped at the fourth of a series of identical doors. Gildern had memorized the layout of the Residence on the flight down. This was the library.

The robot opened the door and Gildern stepped inside behind him. And there were Kresh and Leving themselves. Both here, precisely as he had guessed. Kresh seated behind a desk, Leving sitting in one of the two chair facing the desk.

“Jadelo Gildern of the Ironheads,” the robot announced, and backed away into a robot niche.

“Governor, Dr. Leving,” said Gildern. “Thank you so much for allowing me to arrive so-informally. I think you will find it to our mutual benefit if this visit is kept as quiet as possible.”

“What do you want, Mr. Gildern?” the governor asked, his voice calm and imperturbable.

Gildern walked up to the desk, made the slightest of bows to Dr. Leving, and smiled at Kresh. “I’m here to give you a present, Governor. Something you’ve wanted for quite some time.”

“And in return?” Kresh asked, his voice and face still hard and expressionless.

“And in return, I simply ask that you do not ask, now or in the future, how I got it. No investigation, no inquiry, no official legal proceedings or private researching.”

“You got it illegally,” Kresh said.

“My condition is that you do not ask such questions.”

“Just now I made a statement,” said Kresh. “I asked no question. And I’m not accepting any conditions. I’m sworn to uphold the law, as you may recall. And I might add that it is generally unwise to request an illegal service of a government official in front of witnesses. “ He nodded toward Leving and the robot in its niche.
