“We have ascertained, through Tierlaw Verick’s statement, that Caliban and Prospero were almost certainly the last to see Governor Grieg alive,” Donald said. “I have placed an all-points bulletin for their capture, but it seems unlikely we will apprehend them quickly-especially if we do not have the full cooperation of the SSS. Neither the Rangers nor our own department have arrest powers here, or facilities for performing inquiries.
“Neither Prospero nor Caliban are presently available or traceable via hyperwave, and both have duties that require them to be out in the field a great deal. It is possible they are following their normal routines, but are simply out of touch. It is also possible that they have gone into hiding. We will do all we can to trace them, given the limitations of our circumstances. ”
Interesting that Donald would start with the robots, Kresh thought. He was focused, perhaps overfocused, on them. It would be best to keep in mind that in this investigation at least, Donald was not likely to be even remotely as objective as he normally was. Clearly, he wanted Prospero and Caliban to be guilty. A biased robot. As if there weren’t enough problems on this case.
“How reliable is Tierlaw’s statement?” Kresh asked.
“As best I could ascertain, all of his bodily reactions were consistent with a man under great stress giving a truthful statement. I believe that he spoke the truth, “ Donald said.
And that was the least-qualified pronouncement Donald had ever made concerning his lie-detector function. Enough so that Kresh felt unsure. Usually Donald made a speech three times longer than that about the uncertainty of such measurement. No doubt about it-he wanted the robots to be guilty.
“We should be able to check his story out against Grieg’s appointment diary,” Devray said. “That’s something. But at least we have a lead, and suspects.”
“Even leaving aside the First Law question, I can’t see what possible motive Caliban and Prospero could have for attacking Grieg, or why they would have been so clumsy about it,” Fredda protested. “Yes, Caliban has no First Law. In theory, there is nothing to prevent him attacking anyone he likes. But there’s nothing preventing me, or you, either. And yes, Prospero’s First Law does not enjoin him to prevent harm-but I can’t imagine Prospero splitting hair so fine as to interpret that as participating in a murder but not actually firing the weapon-which is what you’d have to have here.”
“But you do grant,” Devray said, “that there is nothing in Caliban’s absence of Laws that would prevent him from killing Grieg? And that there is nothing in the New Laws that would absolutely force Prospero to prevent the attack?”
“Yes, but-”
“So one of them could kill and the other could stand idly by,” Devray said, his tone a bit badgering.
“In theory, yes,” Fredda admitted, with massive reluctance. “But it makes no sense. Grieg was the best friend the New Law robots ever had. What would make them want to kill him?”
“Plenty,” Devray said. “I have an appointment-had an appointment-with the Governor for later this morning. We were going to talk about a proposal I had submitted last week.”
“What sort of proposal?” Kresh asked.
“One for the destruction of all New Law robots,” Devray said.
“What? Have you taken leave of your senses?” Fredda demanded.
“No, ma’am,” Devray replied, his voice bland and professional. “But I’m damned sick and tired of chasing rustbackers. The N. L. s are at the focus of a whole new series of crimes-rustback smuggling, restrictor removal, and the founding of illegal settlements.”
“Settlements?” Kresh asked.
“Well, one settlement, anyway,” Devray said. “They call it Valhalla. It’s supposed to be somewhere on the far side of the planet from here, somewhere in the Utopia region of Terra Grande. I don’t even know if it exists-but it’s where half the rustbacks we catch seem to be heading. And I’m tired of wasting time and effort chasing rumors. I told the Governor the rustbacks and the New Law robots were more trouble than they were worth, and it was time to admit it and move on.”
“But they work!” Fredda protested. “New Law robots represent half the work force on Purgatory.”
“And they were supposed to be all of it-except they’re only about a third as productive as Three-Law robots. Every department has been forced to pull in human workers, because the Settlers don’t allow Three-Law robots to have the run of the island. If the New Law robots were worth all the trouble they cause, that’d be one thing,” Devray said. “But if anything, they’re slowing down the reterraforming project.”
Kresh was surprised to see Devray that interested in terraforming-and then realized he shouldn’t have been surprised at all. The Rangers only did law enforcement on the side. Terraforming was much more their side of the street.
“Was-was the Governor considering the idea?” Fredda asked.
