Utopia - By Isaac Asimov,Roger E. Allen Page 0,53

glanced at the time display. They ought to be nearly done by now. The planning team had expected the physical target, Lentrall's actual office, to be the easy part. All the operations team had to do was steal or destroy every piece of paper and every datapad and record cube that might have anything to do with the comet. The planners had expected the computer system to be trickier. Still, it would be doable. Other people might well have found it impossible to manipulate the university's computer system, but it was, after all, the Settlers who had installed it.

And it was the Settlers who could wipe Davlo Lentrall' s files clean, when they wanted to do so. And once those files were cleared, they would have lost the comet coordinates. They'd never be able to find the comet again in time.

At least she hoped so.

"I MUST ADMIT that I am growing concerned," said Prospero, his voice a bit on edge. "This terrorist attack on Government Tower might well have some indirect causal link to us, Caliban." The two robots, New Law and No Law, stood facing each other in an office just off an underground passageway on the outskirts of Hades. "I fear there may be consequences."

In days gone by, they had used the semi-abandoned tunnels as hiding places, places to go when they were in fear of their lives. Now, at least for the moment, they were unhunted. They had a legal right to be in the city, with passes signed and sealed by all the pertinent authorities. They could at least in theory go anywhere in the city. In practice, there were places where the residents would not worry too much about the legal niceties. There were still robot-bashing gangs out there who had no use for New Law robots.

But for the most part, Caliban and Prospero were safe in Hades. Indeed, they had spent the morning on a number of routine errands, calling at a number of places around town to order this equipment and make that payment. In plain point of fact, Caliban had been surprised by the number of minor things Prospero had been compelled to deal with in person, and the amount of time he had taken in doing so.

But now, at long last, they were by themselves, underground. It was possible to let down their guard, just a trifle. It was a need for privacy, more than a need for survival, that brought them to this place. But still, there was no harm in precautions. The lighting, for example. The chamber was pitch-black as seen by human eyes, in visible light, but the two robots were using infrared vision, and could see each other easily.

Caliban selected a chair from the dusty and worn-looking collection in one corner of the room, set it upright, and sat down. "I do not understand what makes you think there might be some link to us," Caliban replied. "It is obvious that one group of humans has attacked another. That is hardly something new. I do not see why it matters to us. Do you have some connection to the responsible parties?" It was an indirect and overcareful question, but even so it disturbed Caliban that the notion of Prospero being involved should even have occurred to him.

All he knew about the attack was what they had learned from the news reports-that some unknown group, for unknown reasons, had staged a complicated assault on Government Tower. It had not escaped Caliban's notice that the attack had destroyed a number of robots, but had not harmed any humans. It would require the most miserly possible interpretation of the New First Law for any New Law robot to be a party to such a thing, and Caliban could not imagine why they would want to do it, but it would, at least in theory, be possible.

Prospero turned toward his companion, but he did not answer the question. Instead, he addressed him in severe tones on another matter. "Why do you sit?" he demanded. "Humans might need to rest their legs, but we have no such needs. There might be social conventions regarding physical posture and position among humans, but not between robots. We must play such games in their presence, but there are no humans here. You need not keep on with your playacting."

Caliban was well aware that Prospero had not answered him, and had instead gone off on a tangent. No doubt he hoped to distract Caliban from his
