“But you put many New Law robots at risk by sending them to such a place,” Lancon-03 objected.
“I expose a few to slight danger for the greater good of all. But I do more than that,” he said.
Prospero turned toward the view window that took up most of one wall of his office. Prospero looked down on the interior of Valhalla, on the brightly-lit streets, on the graceful arcing ramps that led from one level to another, on the busy robots hurrying along with their belongings from one place to another, preparing to leave this graceful, tranquil city under its sky of stone. This city was all they had, the fruit of their own labor, the greatest achievement of the New Law robots. And the humans were preparing to smash it down into nothing, to wipe it out as if it had never existed, if doing so would be to their advantage. There was a lesson there for Prospero.
“I propose,” he said, “to take as much advantage as possible of whatever opportunities are presented to me by this disaster.”
IT WAS TIME.
After the endless hours of checks and counterchecks, after endless dress rehearsals, after wringing any number of bugs out of the system, all of it was done. And it was time.
Governor Alvar Kresh paced back and forth behind his console, and looked up again, for the thousandth, the ten thousandth time, at the two hemispheres on their pedestals, the two control center units, the two oracles who could predict, and even shape, the future—if one dared to let them.
Kresh felt as if he had spent his whole life in this room, and the rest of the universe was little more than a vague and distant dream. He smiled wearily. Unit Dee no doubt felt much the same way. To her, this whole world was a dream, though one of mathematical sharpness and clarity.
Soggdon was there with him, and Fredda, and Donald, and all the others, the roomful of experts and technicians and specialists and advisors who had seemed to appear out of nowhere, unbidden, drawn in by nothing more or less than the crisis itself. But, in the final analysis, there was no point in any of them being there. He had heard what they all had to say, and considered their opinions, weighed all the pros and cons again and again. There was nothing more any of them could tell him that he did not know already. Not even anything more than Dum and Dee might say.
In the midst of all of them, he was alone. The one person who, by rights, should have been there, was not. But Davlo Lentrall was still with the comet diversion fleet. The first and most important phase of the fleet’s work was now done. Now they had only to monitor the comet, track it, watch the telemetry.
Assuming they had to do even that. If he, Alvar Kresh, planetary governor of Inferno, decided to say no, to turn his back and walk away, Comet Grieg would go sailing off into the darkness, not to be seen for another two centuries. There would not be much point in watching its telemetry in such a case.
Nor was there much point in considering the possibility of such a case ever coming to pass. Alvar Kresh knew what he had to do. There was very little point in pretending otherwise. How could he possibly walk away from it all now, after so much had happened? How could he say no, and spend the rest of his life watching the planet slowly decay, spend the rest of his life asking himself what if, telling himself if only?
He had to go forward. He had no real choice.
And that was the part that terrified him.
Forcing himself to be calm, he picked up the headset and put it on. “Unit Dee, Unit Dum,” he said. “This is the governor.”
“Yesss, Governnorrr,” the unison voice replied. It startled Kresh to hear the two speaking together once again. It had been quite some time since they had done that. Was it because Dee recognized the gravity of the event? Some sort of effort at ceremony? Or was it for some other reason, or at random, for no reason at all, or because Dee was continuing to brood and wonder, and becoming less and less stable as she did so?
“I have reached my decision,” he said. But he did not speak the words yet. Could he trust Dee with the job? Perhaps he should take the control of the maneuver away from Dee and Dum, tell the comet diversion task force to perform the bum manually.
But no. Better to let Dee have the practice, make sure all of her control connections to the comet’s attitude control and thruster systems were working. They would have to use her either to control terminal descent or Last Ditch. Better to let her have a test drive, as it were. There was a nice long window for the comet diversion bum. By adjusting the thrust of the initial bum and the attitude of the comet, they could perform the bum any time in the next twelve hours. If some connection failed, if the bum was inaccurate, they would have time to fix it, or decide to abort and perform an emergency lateral bum to throw the comet well clear of the planet. Not so in the rapid-fire sequence of the terminal-phase breakup of the comet. Best to test as much of the system as possible now. This was the easy part. The hard stuff would come later.
And if he didn’t trust Dee, he shouldn’t let the comet diversion happen at all.
“I hereby order you to perform the planned diversion maneuver on Comet Grieg,” he said, and the room was deathly quiet.
“Verrry wellll, Governorrr,” said the unison voice. “Weee shalll commmmence the fffinall countdown in fourteen minutes, thirteen seconds. Tttthe burnnn willll commence one hourrr later.”
“Thank you, Dee. Thank you, Dum,” said Kresh. He took the headset off and sat down heavily in his console chair.
“By all the forgotten gods,” he said. “What have I done?”
FREDDA AND ALVAR went outside, and Alvar, at least, was very much surprised to discover that it was full night. How long had it been since he had last left the control room? Twelve hours? A day and a half? Three days? He felt sure that if he concentrated hard enough, he could work it out, remember the last time he had come out, the last time he had gone in.
But there was not much point to the exercise. It was over, and he was out, and that was all that really mattered.
Fredda took him by the hand and led him away from the cold sterility of the Terraforming Center, out away from the lifeless stresscrete of the parking lots, and out onto the cool green lawns that surrounded the Center. “Look,” she said, pointing up into the western sky. “There it is.”
Kresh looked up in surprise. “I’ll be damned,” he said. “So it is.” He had never seen Comet Grieg before. There it was, a fat, featureless golden dot hanging in the darkness. It had no tail, showed no features, but there it was. It seemed incredible that something that obvious should have been so hard to find. But he knew he was seeing the highly reflective sunshade parasol, and he knew the comet was moving fast, straight toward them. Considered as a question of logic, it made perfect sense that it would get closer, and appear larger and brighter as it did so. But still, somehow, it was a shock to see it up there.
He had seen its image endless times in the pictures beamed back from the diversion task force. He had seen it modeled, dissected, shown in false color detail, symbolized by a formless dot in an orbit simulation—but he had never seen the thing itself. There was something jarring, startling, in seeing the comet firsthand, in receiving direct, sensory, personal proof that it was real, that it was no simulation, no abstraction, but a flying mountain of ice and stone that he had ordered dropped onto this world.
