"Wait, wait. You're saying that something drew all the higher-level functions away from its primary duties?"
"More or less. The maintenance nodes show exponentially increased stimulation, as if a tremendous amount of data was suddenly being pumped to those sites and demanding that the RI pay attention. And it did. Complete attention. Basically, everything it was supposed to focus on became secondary. Not even that. Quaternary. The only thing it seemed to be noticing outside these nodes were the mobile units."
"And when it came back online?"
"From what I can see, it came back exactly at the point that it left-with one difference, the time chop. It knew that minutes had gone by during which time it was not paying attention. It couldn't escape the conclusion that it had failed. Collapse began almost immediately."
"Thales," Derec called out, "are you still running Union Station?"
"No, Derec, not all of it," the RI responded. "I am being shut out systematically as systems are being changed over to newly installed Imbitek systems."
"But you were doing it all?"
"For twelve hours, twenty-three minutes, Derec."
"While you maintained full oversight of Union Station, did you run a diagnostic of satellite systems?"
"Yes, Derec. I needed to know what I had to work with. Standard procedure in a new environment."
"Of course. Did you find anything unusual?"
"Several systems were of a type of imbedded technology with which I am unfamiliar. Nothing out of my capacity to interpret and operate, only new configurations."
"What about… Rana, is there a list of those maintenance nodes?"
"Sure." She touched contacts. A list appeared on her screen.
"What about these sites, Thales?" Derec asked.
"There was nothing at those sites, Derec. "
"What do you mean, nothing?"
"I mean that I found no corresponding systems of any sort answering my diagnostic interrogatory at those sites."
"But the Union Station RI showed them to be active."
"I cannot account for the discrepancy, Derec. I acknowledge the data from the RI, but my own diagnostic and analysis showed nothing at those sites. It is possible that those sites suffered damage or were programmed to operate only at predetermined times or were programmed to shut down at a predetermined time."
"How much access do you still have to Union Station?"
"I have been excluded from sixty-two percent of the systems," Thales stated.
"Can you still monitor those sites?"
"Three of them are still within my sphere."
"Watch them. I want to know if any activity occurs at all at those sites. The method of exclusion-can you work around it?"
"Do you mean can I bypass it?"
"Yes."
"I can, Derec, but it is against-"
"Never mind that. This is a priority. Humans may be in danger as a consequence of those sites resuming some operation. I want you to circumvent the exclusions if possible without alerting anyone outside Phylaxis and keep a monitor on them. Understood?"
"I understand, Derec. "
"Continue, Thales."
"Nothing there?" Rana said. She waved a hand at the screens displaying the shattered remnants of the RI. "That's a lot of damage for nothing."
"Those sites were shut down," Derec said. "I'd love to know how they did that without leaving a physical trace, though. Something should be there, even if it's only an I/O port. Which reminds me, I got in there last night."
"Where? Union Station?"
"Back in the service sections, yes. I found something…" He went to his own console and retrieved the paper with the sample. "I need this analyzed," he said, opening it. "This was all through the circuitry in one of the maintenance nodes. It's hard and brittle. I hope there's enough here."
"I'll set Thales up on an analysis," Rana said, peering at the flakes suspiciously.
Derec glanced at the screens. "A positronic brain is joined to its realtime perception in a one-to-one relationship. It has to be that way or interpretive errors creep in and there's a kind of subjective drift."
"But robots interpret things all the time."
"True, but they have their core template to use as a standard. If you look at how they interpret you'll see that they're damnably literal. There was a classic case once of a newly uncrated robot completely disbelieving that humans had built it. The only evidence it could see were the humans supervising it and clearly they couldn't build one, so it must have been a lie. The Three Laws prevented it from doing other than its duty to protect and obey them, but only within certain limits, and it came to believe that robots were created by another machine."
"I thought that was apocryphal."
"Maybe. I've heard it said that the core template came directly out of that incident. But apocryphal or not, it illustrates the point. Positronic robots rely on the concrete to function. If they didn't, they could easily develop neuroses based on abstract concepts of humans they don't even know coming to harm."
"Robots having an existential crisis."
"Something like that. So we give them strict associational and sensory parameters by which to recognize what is real. That way they can determine optimum hierarchical responses to orders given by humans that may conflict with First Law imperatives and likewise permit them to make similar assessments in Third Law situations. Judgements like that demand concrete definitions."
"But what if you substituted those definitions with others? Or one set of perceptions with a different set?"
"They're designed to shut down if they detect that kind of sensory shift. You ' d have to actually bypass their sensory apparatus to do that, but bypass it without any interruption in the sensory input, and consistent with the core template."
Rana tapped one of the screens. "This brain thought it was playing a game. All it perceived, apparently, was the game. The game became its concrete definition."
"Which is impossible. Any code coming in from outside would cause a complete disruption of normal function."
"Unless it didn't come from outside."
"You mean like a parallel system built into its matrix?"
"Bogard worked that way."
"In a very limited fashion. Bogard's buffers simply bypassed crisis situations. It still perceived reality-"
"It just conveniently forgot some of it. What's the difference?"
None, Derec thought, staring at the screens. He had recognized the similarity in the paradox loops the other night. He had hoped it had been a fluke, but Rana had a point. Someone had devised a more complete way to divert a positronic matrix, and not just part of it.
The com chimed.
"Yes?"
"Mr. A very?"
"Speaking."
"This is Ambassador Chassik."
"Yes, Ambassador," Derec said, wincing. "I apologize for not returning your calls yesterday, but I was out of the lab-"
"I understand that, Mr. Avery. I've reached you now and that's fine. I wanted to get together with you to discuss certain matters concerning the removal of the RI from Union Station."
Derec glanced at the time. Almost six-thirty. "It's rather early, Ambassador. When did you have in mind?"
"The sooner the better. I'll send a limo."
"Now? But-"
"Thank you, Mr. Avery. I'll see you in a short while."
"Don't you love not having to make up your own mind?" Rana asked, grinning. Gale Chassik had the heavy look of someone who had done considerable physical labor during his life, which was incongruous in his case as he was a Solarian. Spacers did not get unnecessarily physical; they left that to their robots.
"I apologize for the circumstances, Mr. Avery," he said, pouring two glasses of amber fluid. He set one on the table beside Derec and took his own to the chair opposite. "Unfortunate times."
"How can I help you, Ambassador?" Derec asked, ignoring the glass. He folded his hands in his lap and waited.
"I wanted to h
ave a talk with you about the Union Station RI."
"In what respect?"
"Your analysis of its condition. What you think happened."
"I have no idea what happened. "
"It's been two days-"
"Nearly three, Ambassador, and Phylaxis was removed from any involvement with it at the end of the first day."
Chassik frowned. His forehead seemed to contract. "Removed. But I understood-"
"Normally, Phylaxis Group would be doing the forensics, but Special Service assumed full control of the investigation and barred us from all the relevant material. Surely you knew."
"Your people have been working with us on decommissioning the mobile units. I assumed…"
Derec nodded. "To answer your question, sir, I have no idea what happened to the RI. The unit is a Solarian brain, isn't it? The company that did the original installation is removing it. Didn't they tell you any of this?"
Chassik snorted. "Terran regulations. They aren't allowed to discuss it with anyone, including me, until such as time as, et cetera. I'm sure you've heard the same excuses." He narrowed his eyes at Derec. "You aren't even doing oversight on its removal?"
"No, sir."
"Hmm. Odd."
"I can't disagree. "
"Well. Do you have any theories, Mr. Avery?"
"No, not even a hypothesis. At best I would be making a wild guess."
"Please."
"Somehow, coding was introduced into the RI that effectively distracted it from its primary responsibilities and redirected it. When the assault occurred, the RI was playing. It never saw what was happening."
"That's not possible."
"Again, I can't disagree. Without access to the unit, though, I can't begin to tell you why or how."
Chassik sipped his drink thoughtfully for a few moments. "Mr. Avery, I don't think I need tell you what sort of consequences we're looking at. I don't believe it's unlikely that relations with Earth could be severed."
Derec wanted to argue, but in truth what Chassik said seemed all too likely. One of the core issues of the conference, surrounded by all the trade talk and good will hype, was an agreement to allow robotic inspection of all Earth-Spacer shipping, in both directions. That meant allowing robots onto Terran vessels, a condition too few on Earth approved. It only seemed possible because of Eliton's efforts and the general esteem which Ambassador Humadros commanded and the fact that a great deal of money was involved. The Union Station RI and its satellite systems had been intended to showcase positronics on Earth, to "educate" Terrans and ease some of the prejudice. Now that it had failed so dramatically and catastrophically…
"I'm not sure what I could do to help, Ambassador," Derec said finally.
"Solaria stands to lose a great deal over this incident. Our reputation is at stake, here and at home. So you will understand my desire to know as much as possible about what happened. Would you be willing to do an analysis of the RI after it's been removed from Union Station? Off the record?"
"Off… I'm not sure I understand."
"On the quiet. I'm afraid it would not be authorized by anyone other than me. I could… 'borrow' the unit before it gets shipped back to Solaria."
"What good would that do? If I found something"
"Then it becomes my affair and I could do something with it. But without any knowledge of what happened, I'm helpless."
"It would have been better had the unit not been removed."
Chassik shrugged. "I can't stop it."
"Let me think about it, Ambassador," Derec said. "I'm not sure such an analysis would give you anything worth using. Off-site like that, without any kind of witness to the process, it could be claimed that anything I find is manufactured."
"Would it be?"
"What?"
"Claimed. You know these Terrans a little better than I, perhaps. You've been here longer."
"Think about it, Ambassador. Under similar circumstances, what would you claim? They aren't really that much different."
Chassik's eyebrows raised fractionally, but he nodded and smiled. "Don't take too long to give me your answer, Mr. Avery. There's a window of opportunity here."
"I understand, Ambassador."
Chassik pointed at the glass beside Derec. "You didn't touch your drink."
"It's a little early for me."
"Too bad. Something called Beam's Choice. I must confess, I don't find much about Earth superior, but they make fine whiskey." He finished his own glass. "A present from one of their industrialists. They like giving tokens here."
"When they can."
Chassik nodded and stood. "It was pleasant talking to you, Mr. Avery. And do let me know soonest on your decision."
"Yes, sir. Thank you."
Derec followed the waist-high mobile unit down the corridors to the elevator, trying to work loose the tightness between his shoulders. Nothing just said made any difference to anything; the entire meeting could have been done by comlink with the exception of the illicit offer to allow. Phylaxis access to the RI after its removal from Union Station. So that, Derec decided, had been the true purpose of the meeting.
Which made no sense if Special Service had impounded the RI. If they had not, then what was the purpose of assuming complete jurisdiction of the investigation? And if they had, how would Chassik get his hands on it? True, it belonged technically to Solaria and would eventually be shipped back, but not before Terran analysts ripped it apart. By then, any analysis Derec might perform would be useless. Nothing would be left to analyze.
Derec rode the elevator down to the garage, his unease increasing. Chassik had to have known Phylaxis was barred from the investigation. Well, there was truth to the implication of bureaucratic territoriality-it was possible no one from Special Service, the Station, or his own people had told him anything-but surely Ariel would have said something, being the liaison from the Calvin Institute.
Too many things made less and less sense.
"Where would you like me to drop you, sir?" the limo asked him.
Derec hesitated. "What time is it?"
"Nine-ten, sir."
Two hours at least before his meeting with Ariel, all the way north of the Capitol Mall to Franklin Park. That was a good thirty-minute drive…
"Ford Theater, please."
"Yes, sir."
The limo started up and headed for the exit.
Eighteen
Ariel waited nervously at a small table by a massive pillar and watched the throngs enter and leave the sprawling kitchen. It had been years since her last visit to one of these huge communal dining areas; the place triggered memories-some pleasant, others unwelcome and long neglected.
Derec wandered in with a crowd of school kids who were all dressed in bright blue-and-yellow jumpers and wearing their ID badges prominently around their necks. He got in the queue, picked up a tray, and went through the line.
He drifted by her table, then looked again. He made an exaggerated grin and ambled over, everything about him suddenly announcing salacious intent.
"Excuse me, but I couldn't help notice," he said, just a bit too loudly. A few people turned to look, then as quickly turned away. "You look lonely. Mind if I join you?"
Ariel almost laughed. It was so blatantly clichйd she wondered that anyone could possibly accept such an invitation.
"I don't think" she began.
"You're that friend of Kate's, aren't you? Down at the data import pool? I'm Massey."
Ariel looked away, working at her smile. "I'm sorry, I didn't recognize you at first. Please."
Derec slid into the chair opposite her. "Come here often?"
"Enough," Ariel hissed.
"Sorry. Couldn't resist." He started sorting out his tray. "So why here?"
"I left through a service access and took the strips. No limo."
Derec glanced at her. "Dressed down, too, I see."
She had worn a single piece of dull brown and a bright red jacket that glistened wetly. "
It might have been worth it.
"Maybe." He tore off a piece of bread and dipped it in the thick gravy around his slab of meat product. "You know, I've eaten at the best, but there's still something primally appealing about this place."
"You're joking. That's disgusting."
He gestured at her glass of milk. "And you look like a very convincing T rating, sitting in your home kitchen without any food."
"We won't be here that long. Hurry up."
"Are you going to tell me what we are here for?"
"The body we saw."
"Which one? Eliton's?"
"Yes. It wasn't." She went on to update him on the six Managins and the fact that now, according to Senator Jonis Taprin, Bogard had killed the three Mia had apprehended, then self -destructed, killing Mia as well.
Derec frowned and forked a chunk of meat into his mouth. He chewed thoughtfully for a time. "Of course, you know that's not true."
"Of course I do." He gave her a skeptical look. Impatiently, she went on. "I may disagree with the 'looseness' you've built in to Bogard, but if it kills someone it will be by inability to cope, not through intent. Those three men were alive when Mia was taken off to the hospital."
"All right. So what are we doing up here?"
"Looking for ambulances."
He looked puzzled, then smiled. He nodded, chewing. "You know, you certainly are"
Ariel held up a finger. "Don't carry the charade too far."
Derec chuckled. She watched as he ate everything on his tray.
"Are you finished?"
"I am now. All I had this morning was coffee."
"No wonder it tasted good."
He stood. "Shall we go chase ambulances now?" They took a strip east, toward the convention district.
"The newscams followed Eliton's corpse out of the gallery and to the ambulance," Ariel said. "We got a clear ID on the vehicle. Mia called Reed and told them she was an insurance adjuster and needed to verify ID numbers on the ambulances servicing them."
