off. Room lights on.”
The image of the planet aflame died away, and the lights came up to
reveal a perfectly ordinary living room in a perfectly ordinary residence. The
only unusual object in the room was the highly sophisticated simglobe
projector sitting in the center of the room.
Davlo Lentrall walked over to the low, stubby cylinder that was the
simglobe unit, and tapped the top of it with his finger. Not even the most
advanced Settler models could do what this unit could do. He ought to know. He
had designed and built it himself. He savored the satisfaction of the moment,
and all the effort that had gone before it. It was his, all his. He had
discovered the comet. In a rare burst of modesty, he had named it, not for
himself, as called for by tradition, but for Chanto Grieg, the murdered
governor who had spurred the reterraforming project that had saved the planet.
Or at least bought the planet some time, so that Davlo Lentrall and Comet
Grieg could finish the work that Chanto Grieg had begun. There was a symmetry
there, a bit of poetry that would appeal to the historians. Posterity would
remember Davlo Lentrall, no matter what the comet was called.
Of course, there was no point in discussing such matters with his
robotic assistant. Kaelor would only remind him of the things that were bound
to go wrong. But Davlo could not let such a triumphant moment go without
saying something. “It worked,” he said at last.
“Of course the simglobe works, Master Lentrall. It has worked every time
you operated it. Why should it fail now?”
“I meant the comet-capture, Kaelor, not the simulator.”
“I must point out that you forced it to work,” said the robot Kaelor.
“What, exactly, do you mean?” Lentrall asked. Kaelor was a useful
servant, but dealing with him required a good deal of patience.
“I mean, sir, that you are making a series of unwarranted assumptions.”
Davlo held back his temper, and forced himself to be patient. Kaelor had
been designed and built to Davlo’s custom specifications, the most important
of which was to hold First Law potential to the lowest possible level when
judging hypothetical situations. A lab-assistant robot with First Law set to
the normally super-high levels of Infernal robots would have been utterly
incapable of assisting him on the sorts of experiments Davlo was interested
in. Even before he had stumbled across Comet Grieg, Davlo had been involved in
Operation Snowball, a project that required the contemplation of a great many
risky alternatives in order to find the safest way to proceed.
There was scarcely a Three-Law robot on the planet who would have been
willing to work on Snowball, let alone operate the simglobe to test ideas for
bringing Comet Grieg in. Few robots would even be willing to help set up the
problem, on the grounds that the simulation could pave the way for letting a
real comet strike the real planet--which would be dangerous to humans in the
extreme. Davlo had therefore ordered a custom-built robot for his Snowball
work, and been glad to have him when he realized Grieg’s potential.
It had taken a lot of argument and discussion with the robot designer,
an exceedingly conservative gentleman who was most reluctant to put the
slightest restriction on First Law, but the result was Constricted First Law
001--CFL-001. Tradition and convention would have required Davlo to named CFL-
001 something like Caefal, or Cuffle, or even, as one waggish colleague
suggested, Careful. But none of those appealed to Davlo, and he had come up
with Kaelor instead.
But, either as a side effect of constricted First-Law potential, or
merely as the consequence of the normal random subpathings of his positronic
brain, Kaelor was also possessed of a dour, even depressive, outlook on life
and the universe. “What are these assumptions, Kaelor?”
“You’re assuming you can hold the comet together during the original
guidance explosion,” said Kaelor, “and then assuming you can split it apart in
