Partnership. Part 27

Polyon laughed without humor. "Fa.s.sa, dear, to righteous souls like Forister and General Questar- Benn we're all monsters. I should have remembered how you sucked up to them before, helping them trick me. Did you think that would save you? They'll use you and throw you away like your father did."

Fa.s.sa went white and still as stone. "We don't all take such a simple-minded view of the universe," Forister said. "But, Fa.s.sa, you can't - "

Darnell's fingers were twitching. Polyon nodded.

Slowly, too slowly, Darnell raised the needier. He gave Forister ample time to grasp Fa.s.sa by the shoulders and spin her out of danger. As Forister moved, the cabin seemed to lurch and the lights dimmed. Gravity fell to half-normal, then to nothing, and as Fa.s.sa spun into midair the reaction of Forister's thrust pushed him in the opposite direction. The spray of needles went wide, but one bright line on the for edge of the arc stung through Forister's sleeve and bloodied his wrist. The blood danced out across the cabin in bright droplets that the transition loop pulled out into b.l.o.o.d.y seas; Polyon watched a bubble the size of a small pond 296.

float inexorably toward him, settle around him with a clammy grip, then shrink to a bright b.u.t.ton-sized stain on his shut front.

Fa.s.sa floated back to grasp Forister's flaccid body and cry, "Why did you do that? I wanted to save you!"

"Wanted him - to kill me," Forister breathed. The paravenin was fighting the contractions of his chest.

"Without me - no way to get Nancia's code. Trapped here, all of us - better than letting him go? Forgive me?"

"Death before dishonor." Polyon put a sneering spin on the words, letting the maudlin pair hear what he thought of such brave slogans. "And it will be death, too. See how the s.h.i.+p's systems are failing? What do i you think will go next? Oxygen? Cabin pressure?"

In the absence of direct commands, gravity and lighting should have been controlled by Nancia's *

autonomic nervous functions. Forister groaned as the meaning of this latest failure came through to him.

"She's dying anyway. With or without your help,"

Polyon drove the point home. "And you're not dead yet I lied to you. The needier was only set to paralyze.

Now let's have the access code before Nancia stops breathing and kills us all."

Forister shook his head with slow, painful twitches.

"Come here, Fa.s.sa, dear," Polyon ordered.

"No. I stay with him."

"You don't really mean that," Polyon said pleasantly.

"You know you're far too afraid of me. Remember those shoddy buildings you put up on Shemali? You replaced them free of charge, remember, and I didn't even have to do any of the interesting things we dis- cussed. But if I'd threaten you with flaying alive for cheating me over a factory, Fa.s.sa, just think for a mo- ment what I'll do to you for interfering with me now."

The transition loop was almost a help; the pauses it forced gave Fa.s.sa time to consider her brave stand.297.

Go on, Fa.s.sa," Forister urged when normal speech possible again. "You can't help me now, and I've no wish to see you hurt for my sake."

Thank you for the information," Polyon said with a courteous bow. "Perhaps I'll try that next But I think we'll begin with an older and dearer friend for quick results. Darnell, bring the freak-no, 111 do it; you keep the needier on Fa.s.sa, just in case she gets any silly ideas."

Holding onto the pilot's chair to keep himself in place, Polyon turned and aimed a loose kick at Micaya Questar-Benn. The cessation of s.h.i.+p's gravity had freed her of the artificially weighted prostheses that held her down, but the arm and leg were still flopping loose, free of her control. She was as good as a cripple - she was a cripple, disgusting sight "I want Forister to get a good view of this," he told her politely. "Lock prostheses."

This to the computer; a signal to the hyperchips clamped Micaya's artificial arm and leg together.

"Lay a finger on Mic - " Forister threatened, strug- gling vainly against the effects of the paravenin.

"I won't need to," Polyon said with a brilliant smile.

"I can do it all from here."

A series of brisk verbal commands and typed-in codes caused the portion of the s.h.i.+p's computer that Polyon controlled to transmit new, overriding instruc- tions to the hyperchips controlling Micaya's internal organ replacements. The changes had the full dura- tion of a transition loop to take effect. When they returned to norms.p.a.ce, Micaya's face was colorless and beads of sweat dotted her forehead.

"It's amazing how painful a few simple organic changes can be," Polyon commented gaily. "Little things like fiddling with the circulation, for instance.

How's that hand, Mic, baby? Bothering you a bit?"

"Come a little closer," Micaya invited him, "and find out" But now Polyon had drawn attention to her one 298.

&? 299.

remaining hand; they could all see ho wit had changed color. The fingernails were almost black, the skin was purplish and swollen.

"Keep it like that for a week," Polyon said, "and she'll have a glorious case of gangrene. Of course, we don't have a week. I could trap even more blood in the hand and burst the veins, but that might kill her too fast. So I'll just leave it like that while you think it over, Forister, and maybe we'll start working on the foot as well. Fortunately, the heart's one of her cyborg re- placements, so we don't have to worry about it failing under the increased demands; it'll go on working . . .

as long as I want it to. Want to hear how well it works now?"

A word of command amplified the sound of Micaya's artificial heart beating vehemently, the pulse rate going up to support the demands Polyon was making on the rest of her system. The desperate, ragged double beat echoed through the cabin, droned and drummed and shrilled through a complete transi- tion loop, and no one spoke or moved.

For a heartbeat, no more, Nantia found silence and darkness a welcome relief from the stabbing pain of the input from her rogue sensors. Is this what Sin- gularity is like for softpersons? But no, it was worse than that. In the confused moments before she shut down all conscious functions and disabled her own sensor connections, she had been aware of something much worse than the colors.h.i.+fts and spatial distortions of Singularity; the malevolence of another mind, in- timately entwined with her own, striking at her with deliberate malice.

He means to drive me mad. If I enable my sensors ogam, he'll bleak desperation of die thought came from somewhere iar back in her memories. When, how, had she ever felt so utterly abandoned before? Nantia reached out, un- thinking, to search her memory banks - then stopped before die connection was complete. If sensors could be turned into weapons to use against her, could not memory, too, be infiltrated? Access the computer's memory banks, and she might find herself "knowing"

whatever this other mind wanted her to believe.

Is it another mind ? Or a part of myself? Perhaps Fm mad already, and this is the first symptom. The flas.h.i.+ng, dis- orienting lights and garbled sounds, the sickening whirling sensations, even the conviction that she was under attack by another mind - weren't all these symptoms of one of those Old Earth illnesses that had ravaged so many people before modern electrostim and drug therapy restored the balance of their tor- tured brains? Nancia longed to scan just one of the encyclopedia articles in her memory banks; but that resource was denied her for the moment. Paranoid schizophrenia, that was it; a splitting off of the mind from reality.

Let's see, now - she reasoned. IfTm mad, then it's safe to look up the symptoms and decide that I'm mad, except that presumably I won't accept the evidence. And ifTm not mad, I daren't check memory to prove it. So we'd better accept the working hypothesis that lam sane, and go on from there. The dry humor of the syllogism did something to restore her emotional balance. Although how long I will remain sane, urtder these circ.u.mstances...

Better not to think about that. Better, too, not to remember Caleb's first partner, who had gone into irre- versible coma rather than face the emptiness that surrounded him after the synaptic connections between his sh.e.l.l and the outside world had been destroyed. As a matter of sanity, as well as survival, Nancia decided, she would make the a.s.sumption that somebody had done this to her, and concentrate on solving the puzzle of who had done it and how they could be stopped.

fcf 301.

A natural first step would be to reopen just one sen- sor, to examine the bursts of energy that had come so dose to disrupting her nervous system.... I can't! the child within her shrieked in near-panic. You can't make me, I won't, I won't, fUstay safe in here forever.

That's not an option, Nancia told herself firmly. She wanted to say it aloud, to rea.s.sure herself with the sound of her own voice; but she was mute as well as deaf and blind and without sensation, floating in an absolute blackness. Somehow she had to conquer that panic within herself.

Poetry sometimes helped. That Old Earth dramatist Sev and Fa.s.sa were so fond of quoting; she had plenty of his speeches stored in her memory banks. On such a night as this . . . Nancia reached unthinking for memory, stopped the impulse just in time. She didn't know that speech; she had stored it in memory. Quite a different thing. Try something else, then. Icouid be bounded in a nut- sh.e.l.l, and count myself king of infinite s.p.a.ce, were it not that 1 have bad dreams.... Not a good choice, under the cir- c.u.mstances. Maybe ... did she know anything else?

What was she, without her memory banks, her sensors, her powerful thrusting engines? Did she even existatall?

That way lies madness. Of course she existed.

Deliberately Nancia filled herself with her own true memories. Scooting around the Laboratory Schools corridors, playing Stall and Power-Seek with her friends. Acing the math finals, from Lobachevski Geometry up through Decomposition Topology, play- ing again, with all the wonderful s.p.a.ce of numbers and planes and points to wander in. Voice training with Ser Vospatrian, the Lab Schools' drama teacher, who'd taught them to modulate their speaker- produced vocalizations through the full range of human speech with all its emotional overtones. That first day they'd all been shy and nervous, hating the recorded playbacks of their own tinny artificial voices; Vospatrian had made them recite limericks and non- sense poems until they broke down in giggles and forgot to be self-conscious. Goodness, she could still remember those silly poems with which he'd started off every session....

And quite without thinking or calling on her artifi- cially augmented memory banks, Nancia was oft jjtfc !$* The farmer's daughter had soft brown hair, ? ? b.u.t.ter and eggs and a pound of cheese, ' 1 And I met with a poem, I can't say where, Which wholly consisted of lines like these...."

"Fhairson swore a feud against the clan MTavish; Marched into their land to murder and to rafish, for he did resolve to extirpate the vipers Withfour-and-twenty men andftue-and-thirty thirty pipers..."

Nancia went through Ser Vospatrian's entire reper- toire until she was giggling internally and floating on the natural high of laughter-produced endorphins.

Then, floating quite calmly in her blackness, she set about testing her sensor connections one by one.

She got the mental equivalent of burned fingers and light-blinded eyes more than once during the testing process, but it wasn't as bad as she had feared. The lower-deck sensors were completely useless, as were her navigation computer and the new mathematics and graphics co-processors she'd just invested in.

Everything, in fact, that contains hyperchipsfrom Shemati...

and with that deduction, Nancia knew just who was striking at her and why.

She opened the upper deck sensors one by one, first taking in the sleeping bodies tumbled in the pas- 302.

Even less time than she'd thought, Nancia realized as she took in the standoff in the control room.

General Questar-Benn disabled - of course, the hyper- chips in her prostheses - and Darnell holding her needier on a defiant Forister while Polyon sat in the pilot's chair and played his commands on the com- puter console. That, at least, she could do something about. Nancia struck back, sending her own com- mands to the computer, disabling the console section by section, garbling Polyon's commands as they came in. He tapped out a sequence she did not know; she traced it to its source and with shock recognized her own access code. The musical tones were already sounding in the cabin. But the accompanying syllables weren't stored in the same location.... They have to be somewhere, though. In some part of memory not accessible to my conscious probe. Otherwise my sh.e.l.l wouldn't recognvze and open to them. Nancia felt proud of herself for figur- ing that out, then cold and sick as she wondered how long it would take Polyon to make the same deduction.

And if the syllables aren't where lean consciously retrieve them, how can I block Polyon against doing so ?

She felt queasy from the repeated looping through four decomposition s.p.a.ces, but there was no safe way to leave the loop until she regained full computing and303.

navigational facility, first, let's repair the damage..,. Nancia worked furiously, permanently disabling the sections of her computer system that had been contaminated by the Shemali hyperchips, finding alternative routings to ac- cess the processors that remained untouched. At the same time the worm program unleashed by Polyon squirmed deeper into her system, changing and mutat- ing code as it went, erasing its own tracks so that she could only tell where it had been by the sudden flares of dis- orienting sense input or the garbled mathematics where it had been. She had to find and stop that code before she could do anything else.

Deep in the intricacies of her own system, Nancia agonized as Darnell struck down Forister.

Don't listen. Don't think about that. She would need all her concentration to disable Polyon's rogue code, more concentration than she'd ever brought to bear on the comparatively trivial problems of subs.p.a.ce navigation. Nancia remembered Sev Bryley's training in relaxation and deliberately, slowly calmed herself, drawing energy away from her extremities and center- ing her consciousness on the internal core of light where she existed independent of computer and sh.e.l.l and s.h.i.+p. With some remote part of her awareness she sensed the failure of gravitational systems and the dimming of lights, the shock and concern of her pas- sengers, but she could not afford to divert consciousness to those semi-automatic functions now.

The automatic datacording routines Nancia had set up continued to operate as Polyon began Micaya's tor- ture. Nancia could not counter his commands without breaking her trance; she could not even restore gravity and lights to rea.s.sure Forister. Ignoring Micaya's pain was the hardest thing she had ever done. For the moment, Micaya does not exist. Nothing exists outside this place, this mo- ment, this center. There was the rogue code; she annihilated it in a blaze of energy, destroying deep 304.

fcf memory in the process; like an amputation, she thought, the shaft of pain and the nagging ache afterwards. Now to restore lost functions... Ruthlessly she cutback on the frills and luxuries of her programming, reducing the power that normally fed her autonomic functions. Lights dimmed even further in the control cabin, and the softpersons made comments about an acrid smell in the air. They would just have to put up with it; she needed that processing power to restore her crippled nav programs. Three of the four major math coprocessors were lost; the graphics processor could double for one of them. No time to think about the others. Naritia erased unnecessary programs and dumped others to datahedron, making s.p.a.ce in what little remained of her memory for the processes she had to have. Would that be enough? No chance for tests, no time for second thoughts. She struck back, once, with everything she had; felt hyperchips shriveling to blank bits of permalloy, felt inactive sensors and processors become dead weights instead ofliving systems.

Some animals will gnaw off their own limbs to get out of a trap....

No time to mourn, either. With the "death" of the hy- perchips within Nancia's system, the transmissions that tortured Micaya's cyborgans ceased. The sound of her amplified heartbeat ended between one drum beat and the next. Forister groaned. He thmks fm dead. He would be rea.s.sured in a moment Nancia activated full artificial gravity; Darnell fell to the deck from his wall perch, Fa.s.sa went to her knees. Polyon staggered but remained stand- ing. Nancia beamed commands to the tanglefield wires, Darnell, Polyon and Fa.s.sa were frozen in place, nets of moving lights encompa.s.sing the tanglefield keys at their wrists and ankles and necks. Finally, Nancia spared a t.i.ttle power to bring up the cabin lights and freshen the air.

"FN-935 reporting for duty," she said. "I apologize for any temporary inconvenience...."305.

"Nanda!" Forister sounded dose to tears.

"General Questar-Benn, can you take the pilot's seat?" Nancia requested, "I may need a little help to navigate us out of Singularity."

"Do my best" Micaya's breathing was still ragged, and she leaned heavily on the chair beside her, but she limped to the pilot's seat without help, the prostheses once again responding to her own brain's electrical impulses. "What can I do?"

"I am operating with only one mathematics coproces- sor," Nancia told her, "and my navigation units are nonfunctional When I start the drives, we will move out of this transition loop and into the expansion of whatever subs.p.a.ce we happen to be in. I'll try to maintain a steady path through the subs.p.a.ce options, but I may need you to aid in the navigation. Since the graphics processor is undamaged, I will throw up images of the approaching subs.p.a.ces. Rest your hand on the palmpad and give me a direction at each branch."

"Do my best," Micaya said again, but Nancia noticed it was the prosthetic hand she rested on the palmpad; the other hand was still an ugly purple color, with blackened moons on the swollen fingertips. She remembered what Polyon had said about gangrene.

How much had his hyperchips accelerated Micaya's metabolic processes? Get her to a medic., .but I can't do that, unless somebody helps me surf out of Singularity... and we daren't waitfor the paravenm to wear offfbrister....

. Then Nancia had no more energy to spare for wor- . rying about Micaya or anything else but the waves of transformations that broke over her head, tossed and tumbled her gasping through subs.p.a.ces that j,deformed her body and everyone within, streams of [calculations that escaped her processors. Lost and choking, she sensed a firm hand guiding her up- wards... out... She crunched the last numbers into a tractable series of equations and broke through the 306.

chaos of uncountably infinite subs.p.a.ces into the blessed normalcy of Reals.p.a.ce.

Before she had rime to thank Micaya, a tightbeam communication a.s.saulted her weakened comm center.

"Back so soon, FN? What's the matter? I thought you were headed for Central."

It was Simeon, the Vega Base managing brain. "We had a small virus problem," Nancia beamed back.

"Returned for... repairs."

The rest of the story could wait until she had ab- solute privacy. There was no need to alert the galaxy to the fact that an unknown number of their computer systems were contaminated by Shemali hyperchips.

"Is everything under control now?"

"You could say that," Nancia replied dryly, turning up her remaining sensors and looking over her inter- nal condition. Half her processors burned out, sleeping bodies littering the pa.s.senger quarters, three High Families brats secured in tanglefield and mad as h.e.l.l, Forister twitching with the pins-and-needles of paravenin recovery, and a crippled general bringing them safe into Reals.p.a.ce - "Yes," she told Simeon. "Everything's under control."

* CHAPTERMGHTEEN In the days of repair work drat followed, Nancia began to understand just how much Caleb must have hated being grounded on Summerlands while she went on with a new brawn to complete the task they had begun.

Now she, too, was "convalescent" and temporarily out of the action. To protect herself from the insidious effects of Polyon's hyperchips she had, in effect, crippled herself^ rendering large parts of her own system inoperable; to keep the worm program he had implanted from contact- ing other hyperchips once they got out of Singularity and could make Net contact again, she had slashed through her own memory, ruthlessly excising whole sec- tions of memory banks and operating code.

"It's a miracle you made it back here in one piece,"

Simeon of Vega Base told her, "and you're not leaving Base until you've had a very thorough overhaul and repair. Those aren't my orders, they're a beam from CS. So no argument!"

"I wasn't planning to argue," said Nancia with, for her, unaccustomed meekness. Indeed, after the stresses of that prolonged stay in Singularity, followed by the limping return voyage on one-third power, she had very litde desire to do anything but park herself in orbit around Vega Base and watch the stars wheel by.

Or so she told herself She was tired and injured; she wasn't up to the stressful task of transporting the prisoners and witnesses back to Central for trial It was for more sen- sible to prepare a datahedron of her own testimony, something that could be sent back on the bright new Courier Service s.h.i.+p that came to collect theothers.

Til miss you," Forister said, "but you'll be back in action soon, Nanria. Why, at the speed Central works, you'll probably be returning before the trial's over!

And if you don't" - he hefted the gleaming weight of the megahedron in one hand - "this is as good, for all legal purposes, as having you there. You've trans- ferred datacordings of everything that happened on board or that you perceived through your contact but- tons, right? Should be the most complete - and most d.a.m.ning-record we could ask for."
