the window, and saw to his surprise that they were coming in on final approach to Depot. Good. They could get started right away.

He would be very surprised indeed if Norlan Fiyle didn't have something to tell him about all this. He would send out an arrest team at once.

And while they were pulling him in, Justen was going to inform Kresh about the kidnapper's two demands. He wasn't going to be able to get the comet stopped, but there might just be something he could do about that ransom. He was starting to get an idea.

"DO WHAT YOU like about the ransom," Kresh said to the image on the comm center screen on his office. "We can afford to front the money, if need be. And I agree it could do no harm to keep Gildern in the dark. But that comet is on course, and we're not going to change that."

"Understood, sir," Devray replied. "Thank you for the authorization. I'll keep you informed. Devray out." The screen went dead.

"How long now, Donald?" Kresh asked.

"Initial impact of Comet Grieg is projected to occur in four days, eighteen hours, fifteen minutes and nine seconds. Sir, concerning the rescue of Simcor Beddle, I believe it would be wise if I were to go to the scene and-"

"Donald." Fredda's voice was flat and hard. "You are to leave the room at once. Go to the library and wait. Do not return, and do not take any further action of any kind until called for."

Donald turned toward Fredda and looked at her for a full ten seconds before he responded. "Yes, ma'am. Of course." He turned and left the room.

"First Law makes him want to save Beddle, in spite of Devray and his team being on the scene. I suppose we should have been expecting that," Kresh said.

"I have been expecting it," said Fredda. "Comet Grieg all by itself is enough to set off significant First Law stress in any robot. An event as big and violent as that, with so many chances for danger to humans, would have to set off First Law stress. The only way a robot could deal with that sort of thing at all would be to be active, to do something, to be part of the effort to protect humans from harm. Donald has been part of that effort. It's why he's been able to hold together as well as he has. It helped that the threat up until now has been generalized, unfocused. Something somewhere would probably go wrong somewhere to harm a human. Generalized preventive action was enough to balance that. The general and collective robot effort was enough to meet the general and collective threat."

"But now it is all different," Kresh said.

"Now it's different," Fredda agreed. "Now there is a specific and extreme threat against a known individual. Normally that would not be enough to cause a First Law crisis. A robot on this side of the world would know that the robots on that side of the world would do all that could be done. But with the overarching stress of the Comet Grieg impact on the one side, along with the high probability that Beddle is somewhere in the impact area-that combination of overlapping First Law stresses could force any robot into action."

"What do you mean by action?" Kresh asked.

"Anything. Everything. I couldn't even begin to sort out all the permutations between now and the impact. But the basic point is that Beddle's disappearance could create a tremendous First Law crisis for every robot on the planet. If Beddle is indeed in the impact area-or even if there is merely reason to believe he might be-then any robot made aware of his circumstances will, in theory, be required to go to his rescue, or to work in some other way to save him-perhaps by trying to prevent the comet impact. Suppose some team of robots grabbed a spacecraft and headed for Grieg to try and destroy the comet? Of course, higher-function robots will understand that an attempt to prevent the comet's impact might wreck hopes for reviving the planet's ecology. That would almost certainly result in harm to any number of human beings, many of them not yet even born.

"Then there is the impossibility of proving a negative. Even with the best scanning system in the universe, unless Beddle walks out somehow, there can be no way of being absolutely sure he is not still in the impact area, or the danger
