"The power that's fed into the—I suppose we can call it the horn—of the Necklin field generator is pulsed, definitely pulsed," Vorthys told the Komarrans. "Highly directional, rapid, and adjustable—I almost want to say, tunable."
"That's so very odd," said Dr. Riva. "Jumpship rods have a steady power—in fact, keeping unwanted fluctuations out of the power is a major design concern. Let's try some simulations with the various hypotheses . . ."
Miles woke up, and bent closer, as the assorted theories began to take visible form as three-dimensional vector maps above the vid-plate. Professor Vorthys provided some limiting parameters based on the projected nature of the power supply. The boffins did indeed produce some pretty pictures, but except for aesthetic considerations involving color contrasts, Miles didn't see what was to choose among them.
"What happens if somebody stands in front of the directional five-space pulses from that thing?" he asked at last. "At various distances, say. Or runs an ore freighter in front of it."
"Not much," said Riva, staring at the whirls and lines with an intensity at least equal to Miles's. "I'm not sure it would be good for you on the cellular level to be that close to any power generator of this magnitude, but it is, after all, a five-space field pulse. Any three-space effects would be due to some defocus on the fringe, and doubtless take the energy form of gravitational waves. Artificial gravity is a five-space/three-space interface phenomenon, as is your military gravitic imploder lance."
D'Emorie twitched slightly, but trying to keep a five-space physicist from knowing about the principles of the imploder lance was an exercise in futility right up there with trying to keep weather secret from a farmer. The best the military could hope for was to keep the engineering details under wraps for a time.
"Could it be, I don't know . . . that we're looking at half the weapon?"
Riva shrugged, but looked interested rather than scornful, so Miles hoped it wasn't a stupid question. "Have you determined if it is meant to be a weapon at all?" she said.
"We've got some very dead people to account for," Miles pointed out.
"That, alas, does not necessarily require a weapon." Professor Vorthys sighed. "Carelessness, stupidity, haste, and ignorance are quite as powerfully destructive of forces as homicidal intent. Though I must confess a special distaste for intent. It seems so unnecessarily redundant. It's . . . anti-engineering."
Dr. Riva smiled.
"Now," said Vorthys, "what I want to know is what happens if you aim this device at a wormhole, or, possibly, activate it while jumping through a wormhole. One would in that case also have to take into account effects due to the Necklin field it was traveling inside."
"Hmm . . ." said Riva. She and the sandy-haired youth went into close math-gibberish-mode, punctuated by some reprogramming of the simulation console. The first colorful display was rejected by them both with the muttered comment, "That's not right. . . ." A couple more went by. Riva sat back at last, and ran her hands through her short curls. "Any chance of taking this home to sleep on overnight?"
"Ah," said Lord Auditor Vorthys. "I'm afraid I was unclear to you over the comconsole last night. This is something in the nature of a crash program, here. We have reason to suspect time could be of the essence. We're all here for the duration, till we figure this out. No data leave this building."
"What, no dinner at the Top of the Dome in Serifosa?" said Yuell, sounding disappointed.
"Not tonight," Vorthys apologized. "Unless someone gets really inspired. Food and bedding will be supplied by the Emperor."
Riva glanced around the room, and by implication the facility. "Is this going to be the ImpSec Budget Hostel again? Bedrolls and ready-meals?"
The Professor smiled wryly. "I'm afraid so."
"I should have remembered that part from the last time. . . . Well, it's motivation of a sort, I suppose. Yuell, that's enough of this comconsole for now. Something's not right. I need to pace."
"The corridor is at your disposal," Professor Vorthys told her cordially. "Did you bring your walking shoes?"
"Certainly. I did remember that from our last date." She stuck out her legs, displaying comfortable thick-soled shoes, and rose to go off to the hallway. She began walking rapidly up and down, murmuring to herself from time to time.
"Riva claims to think better while walking," Vorthys explained to Miles. "Her theory is that it pumps the blood up to her brain. My theory is that since no one can keep up with her, it cuts down on the distracting interruptions."
A kindred spirit, by God. "Can I watch?"
"Yes, but please don't talk to her. Unless she talks to you, of course."
Both Vorthys and Yuell returned to fooling with their comconsoles. The Professor appeared to be trying to refine his hypothetical design for the missing power-supply system for the novel device. Miles wasn't sure but what Yuell was playing some sort of mathematical vid game. Miles leaned back in his station chair, stared out the window, and addressed his imagination to the question, If I were a Komarran conspirator with ImpSec on my tail and a novel device the size of a couple of elephants, where would I hide it? Not in his luggage, for damn sure. He scratched out ideas on a flimsy, and drew rejecting lines through most of them. D'Emorie studied the Professor's work and reran some of the earlier simulations.
After about three-quarters of an hour, Miles became aware that the echo of soft rapid footsteps from the corridor had ceased. He rose, and went and poked his head out the door. Dr. Riva was seated on a window ledge at the end of the corridor, gazing pensively out over the Komarran landscape. It fell away toward the stream, here, and was much less bleak than the usual scene, being liberally colonized by Earth green. Miles ventured to approach her.
She looked up at him with her quick smile as he neared, which he returned. He hitched his hip over the low ledge, and followed her gaze out the sealed window, then turned to study her profile. "So," he said at last. "What are you thinking?"
Her lips twisted wryly. "I'm thinking . . . that I don't believe in perpetual motion."
"Ah." Well, if it had been easy, or even just moderately difficult, the Professor would not have called for reinforcements, Miles reflected. "Hm."
She turned her gaze from the scenery to him, and said after a moment, "So, you're really the son of the Butcher?"
"I'm the son of Aral Vorkosigan," he replied steadily. "Yes." Her version of the perpetual question was neither the accidental social blunder of Tien, nor the deliberate provocation of Venier. It seemed something more . . . scientific. What was she testing for?
"The private life of men of power isn't what we expect, sometimes."
He jerked up his chin. "People have some very odd illusions about power. Mostly it consists of finding a parade and nipping over to place yourself at the head of the band. Just as eloquence consists of persuading people of things they desperately want to believe. Demagoguery, I suppose, is eloquence sliding to some least moral energy level." He smiled bleakly at his boot. "Pushing people uphill is one hell of a lot harder. You can break your heart, trying that." Literally, but he saw no point in discussing the Butcher's medical history with her.
"I was given to understand that power politics had chewed you up."
Surely she could not see scars through his gray suit. "Oh," Miles shrugged, "the prenatal damage was just the prologue. The rest I did to myself."
"If you could go back in time and change things, would you?"
"Prevent the soltoxin attack on my pregnant mother? If I could only pick one event to change . . . maybe not."
"What, because you wouldn't want to risk missing an Auditorship at thirty?" Her tone was only faintly mocking, softened by her wry smile. What the devil had Vorthys told her about him, anyway? She was highly aware, though, of the power of an Emperor's Voice.
"I almost arrived at thirty in a coffin, a couple of times. An Auditorship was never an ambition of mine. That appointment was a caprice of Gregor's. I wanted to be an admiral. It's not that." He pau
sed, and drew in breath, and let it out slowly. "I've made a lot of grievous mistakes in my life, getting here, but . . . I wouldn't trade my journey now. I'd be afraid of making myself smaller."
She cocked her head, measuring his dwarfishness, not missing his meaning. "That's as fair a definition of satisfaction as any I've ever heard."
He shrugged. "Or loss of nerve." Dammit, he'd come out here to pick her brain. "So what do you think of the novel device?"
She grimaced, and rubbed her hands slowly, palm to palm. "Unless you want to posit that it was invented for the purpose of giving headaches to physicists, I think . . . it's time to break for lunch."
Miles grinned. "Lunch, we can supply."
Lunch, as threatened, was indeed military-issue ready-meals, though of the highest grade. They all sat around one of the tables in the long room, pushed aside chunks of equipment to make space, and tore off the wrappers from the self-heating trays. The Komarrans eyed their food dubiously; Miles explained how it could have been much worse, getting a giggle from Riva. The conversation became general, touching on husbands and wives and children and tenure and an exchange of scurrilous anecdotes about the fecklessness of former colleagues. D'Emorie had a couple of good ones about early ImpSec cases. Miles was tempted to top them with a few about his cousin Ivan, but nobly refrained, though he did explain how he'd once sunk himself and his personal vehicle in several meters of arctic mud. This led to the subject of the progress of Komarran terraforming, and so by degrees back to work. Riva, Miles noticed, grew quieter and quieter.
She maintained her silence as they all took to the comconsoles again after lunch. She did not resume her pacing. Miles watched her covertly, then less covertly. She reran several simulations, but did not play with further alterations. Miles knew damn well one couldn't hurry insight. This kind of problem-solving was a lot more like fishing than like hunting: waiting patiently and, to a degree, helplessly, for things to rise up out of the depths of the mind.
He thought about the last time he'd been fishing.
He considered Riva's age. She'd been in her teens at the time of the Barrayaran conquest of Komarr. In her twenties at the time of the Revolt. She'd survived, she'd endured, she'd cooperated; her years under Imperial rule had been good, including an obviously successful life of the mind, and a single marriage. She'd compared children with Vorthys, and spoken of an eldest daughter's upcoming wedding. No Komarran terrorist, she.
If you could go back in time and change things . . .
The only moment in time you could change things was the elusive now, which slipped through your fingers as fast as you could think about it. He wondered if she was thinking about that right now, too. Now.
Now, the Professora's ship from Barrayar would be getting ready for its final wormhole jump. Now, Ekaterin's ferry would be approaching the jump-point station. Now, Soudha and his crew of earnest techs would be doing . . . what? Where? Now, he was sitting in a room on Komarr watching a quietly brilliant woman who had stopped thinking.
He rose, and went to touch Major D'Emorie on his green-uniformed shoulder. "Major, can I have a word with you outside."
Surprised, D'Emorie shut down his comconsole, where he'd been checking out some question about available power transformers Vorthys had put to him. He followed Miles into the hall and down the corridor.
"Major, do you have a fast-penta interrogation kit available?"
D'Emorie's brows rose. "I can check, my lord."
"Do so. Get one and bring it to me, please."
"Yes, my lord."
D'Emorie went off. Miles lingered by the window. It was twenty minutes before D'Emorie returned, but he had the familiar case in his hand.
Miles took it. "Thank you. Now I would like you to take Dr. Youell for a walk. Discreetly. I'll let you know when you can come back in."
"My lord . . . if it's a matter for fast-penta, I'm sure ImpSec would want me to observe."
"I know what ImpSec wants. You may be assured, I will tell them what they need to know, afterward." Turnabout, hah, for all those briefings with vital pieces missing Lieutenant Vorkosigan had once endured . . . life was good, sometimes. Miles smiled a little sourly; D'Emorie, intelligently, veered off.
"Yes, my Lord Auditor."
Miles stood aside for D'Emorie to exit with Dr. Youell. When he entered the long room, he locked the door after himself. Both Professor Vorthys and Dr. Riva looked up at him in puzzlement.
"What's that for?" Dr. Riva asked, as he set the case on the table and opened it.
"Dr. Riva, I request and require a somewhat franker conversation with you than the one we had earlier." He held up the hypospray and calibrated the dosage for her estimated body mass. Allergy check? He didn't think he needed it, but it was standard operating procedure; if he didn't have to guess, he didn't have to guess wrong. He tore off a test-dot from the coiled strip of them and walked over to her station chair. She was too startled to resist at first when he took her hand, turned it over, and pressed the tester to the inside of her wrist, but she jerked back her arm at the prickle. He let it go.
"Miles," said Professor Vorthys in an agitated voice, "what is this? You can't fast-penta . . . Dr. Riva is my invited guest!"
That wording was one step away from the sort of Vor challenge that used to result in duels, in the bad old days. Miles took a deep breath. "My Lord Auditor. Dr. Riva. I have made two serious errors of judgment on this case so far. If I'd avoided either of them, your nephew-in-law would still be alive, we'd have nailed Soudha before he got away with all his equipment, and we would not now all be sitting at the bottom of a deep tactical hole playing with jigsaw puzzles. They were both at heart the same error. The first day we toured the Terraforming Project, I did not insist on Tien landing the aircar here, though I wanted to see the place. And on the second night, I did not insist on a fast-penta interrogation of Madame Radovas, though I wanted to. You're the failure analyst, Professor; am I wrong?"
"No . . . But you could not have known, Miles!"
"Oh, but I could have known. That's the whole point. But I didn't choose to do what was necessary, because I did not want to appear to use or abuse my Auditorial power in an offensive way. Especially not on here on Komarr, where everyone is watching me, the son of the Butcher, to see what I'll do. Besides, I spent a career fighting the powers-that-be. Now I am them. Naturally, I was a little confused."
Riva's hand was to her mouth; there was no hive or red streak on the inside of her arm. Well and good. Miles returned to the table and picked up the hypospray.
"Lord Vorkosigan, I do not consent to this!" said Riva stiffly as he approached her.
"Dr. Riva, I did not ask you to." His left hand guarded his right as in knife-play; the hypospray darted in to touch her neck even as she turned and began to rise from her chair. "It would be too cruel a dilemma." She sank back, glaring at him. Angry, but not desperate; she was divided in her own mind, then, which had doubtless saved them both the embarrassment of him chasing her around the room. Even at her age and dignity she could probably outrun him if she were truly determined to do so.
"Miles," said the Professor dangerously, "it may be your Auditorial privilege, but you had better be able to justify this."
"Hardly a privilege. Only my duty." He stared into Riva's eyes as her pupils dilated and she sank back limply in her chair. He didn't bother with the standard opening litany of neutral questions while waiting for the drug to cut in, but merely watched her lips. Their thin tension slowly softened to the stereotypical fast-penta smile. Her eyes remained more focused than those of the usual subject; he bet she could make this a lengthy and circuitous interrogation, if she chose. He'd do his best to cut that circuit as short as possible. The shortest way across a hostile District was around three sides.
"This was a really interesting five-space problem that Professor Vorthys set you," Miles observed to her. "Sort of a privilege to be brought in on it."
"Oh, yes," she agreed cordially. She smiled, frowned,
her hands twitched, then her smile settled in more securely.
"Could be prizes and academic preferment, when it's all sorted out at last."
"Oh, better than that," she assured him. "New physics only come along once in a lifetime, and usually you're too young or too old."
"Strange, I've heard military careerists make the same complaint. But won't Soudha get the credit?"
"I doubt it was Soudha who thought of it. I'd bet it was the mathematician, Cappell, or maybe poor Dr. Radovas. It should be named after Radovas. He died for it, I suspect."
"I don't want anybody else to die for it."
"Oh, no," she agreed earnestly.
"What did you say it was, again, Professor Riva?" Miles did his best to pitch his voice like a bewildered undergraduate's. "I didn't understand."
