Ekaterin was expecting Nikki's next to be something along the lines of, Will I be short? but instead, his brown eyes widened in extreme worry. "Did she die?"

"No, she recovered completely. Fortunately. For us all. She's fine now."

He took this in. "Was she scared?"

Nikki, Ekaterin realized, had not yet sorted out just who Lord Vorkosigan's mother was, in relation to the people he'd heard about in his history lessons. Vorkosigan's brows rose in some bemusement. "I don't know. You can ask her yourself, someday, when—if you meet her. I'd be fascinated to hear the answer." He caught Ekaterin's unsettled gaze, but his eyebrows remained unrepentant.

Nikki regarded Lord Vorkosigan dubiously. "Did they fix your bones with retrogenes?"

"No, more's the pity. It would have been much easier on me, if it had been possible. They waited till they thought I was done growing, and then they replaced them with synthetics."

Nikki was diverted. "How d'you replace bones? How do you get them out?"

"Cut me open," Vorkosigan made a slicing motion with his right hand along his left arm from elbow to wrist, "chop the old bone out, pop the new one in, reconnect the joints, transplant the marrow to the new matrix, glue it up and wait for it to heal. Very messy and tedious."

"Did it hurt?"

"I was asleep—anesthetized. You're lucky you can have retrogenes. All you have to have are a few fiddling injections."

Nikki looked vastly impressed. "Can I see?"

After an infinitesimal hesitation, Vorkosigan unfastened his shirt cuff and pushed back his left sleeve. "That pale little line there, see?" Nikki stared with interest, both at Vorkosigan's arm and, speculatively, at his own. He wriggled his fingers, and watched his arm flex as the muscles and bones moved beneath his skin.

"I have a scab," he offered in return. "Want to see?" Awkwardly, he pushed up his pant leg to display the latest playground souvenir on his knee. Gravely, Vorkosigan inspected it, and agreed it was a good scab, and would doubtless fall off very soon now, and yes, perhaps there would be a scar, but his mother was very right to tell him not to pick it. To Ekaterin's relief, everyone then refastened their clothes and the contest went no further.

The conversation lagging after that high point, Nikki pushed a few last smears of groats and syrup artistically around the bottom of his dish, and asked, "Can I be excused?"

"Of course," said Ekaterin. "Wash the syrup off your hands," she called after his retreating form. She watched him—run, not walk—out, and said uncertainly, "That went better than I expected."

Vorkosigan smiled reassurance. "You were matter-of-fact, so you gave him no reason to be otherwise."

After a little silence Ekaterin said, "Was she scared? Your mother."

His smile twisted. "Spitless, I believe." His eyes warmed, and glinted. "But not, I understand, witless."

The two Auditors left for an on-site inspection of the Waste Heat experiment station shortly thereafter. Waiting carefully for a natural break in Nikki's quiet play in his room, Ekaterin called him in to her workroom to read the simplest and most straightforward article she had found on the subject of Vorzohn's Dystrophy. She sat him in her lap in her comconsole station chair, something she seldom did any more now he had become so leggy. It was a measure of his hidden unease this morning, she thought, that he did not resist the cuddle, nor her direction. He read through the article with fair understanding, stopping now and then to demand pronunciations and meanings of unfamiliar terms, or for her to rephrase or interpret some baffling sentence. If he had not been on her lap, she would not have detected the slight stiffening of his body as he read the line: . . . later investigations concluded this natural mutation first appeared in Vorinnis's District near the end of the Time of Isolation. Only with the arrival of galactic molecular biology was it determined that it was unrelated to several old Earth genetic diseases which its symptoms sometimes mimic.

"Any questions?" Ekaterin asked, when they'd finally wended to the end of the thing.

"Naw." Nikki elbowed off her lap and slid to his feet.

"You can read more whenever you want."

"Huh."

With difficulty, Ekaterin restrained herself from pursuing some more definite response from him, realizing she wanted it more for her sake than his own. Are you all right, is it all right, do you forgive me? He would not, could not, work through it all in an hour, or a day, or even a year; each day must have the challenge and response appropriate to it. One damn thing after another, Vorkosigan had said. But not, thank heavens, all things simultaneously.

The addition of Lord Vorkosigan to the expedition to Solstice made startling alterations in Ekaterin's carefully calculated travel plans. Instead of rising in the middle of the night to catch economy-class seats on the monorail, they awoke at a leisurely hour to take passage on an ImpSec suborbital courier shuttle which waited their pleasure, and would cover the intervening time zones with an hour to spare for lunch before Nikki's appointment.

"I love the monorail," Vorkosigan had confided apologetically at her first startled protest at the news of this change, sprung on her late in the evening when the two Auditors returned from their day's investigations. "In fact, I'm thinking of urging my brother Mark to invest in some of the companies trying to build more of them on Barrayar. But with this case heating up, ImpSec's made it pretty clear they would rather I did not travel by public transportation just now thank you very much my lord."

They also had two bodyguards. They wore discreet Komarran-style civilian clothes, which made them look exactly like a pair of Barrayaran military bodyguards in civvies. Vorkosigan seemed equally able to deal easily with them, or ignore them as though they were invisible, at will. He brought reports to read on the flight, but only glanced over them, seeming a little distracted. Ekaterin wondered if Nikki's restlessness broke his concentration, and if she ought to try and suppress the boy. But a quiet word from Vorkosigan at apogee won an excited Nikki an invitation to come forward and spend ten minutes in the pilot's compartment.

"How is the case going this morning?" Ekaterin asked him during this private interlude.

"Exactly as I predicted, unfortunately," he said. "ImpSec's failure to catch up with Soudha is growing more disturbing by the hour. I really thought they'd have nailed him by now. Between Colonel Gibbs's group, and that team of earnest ImpSec boys we have counting widgets out at the experiment station, my parts list is starting to take shape, but it will be at least another day before it's complete."

"Did my uncle like the idea?"

"Heh. He said it was tedious, which I already knew. And then he appropriated it from me, which I take to indicate approval." He rubbed his lips, introspectively. "Thanks to your uncle, we did get one spot of encouragement last night. He'd thought to confiscate Radovas's personal library, when we visited Madame Radovas, and we sent it off to ImpSec HQ for analysis. Their analyst confirmed Radovas's primary interest in jumpship technology and wormhole physics, which does not surprise me much, but then we got a bonus.

"Soudha or his techs did a superb job of erasing everyone's comconsoles before ImpSec got to them, but evidently no one thought of the library. Some of the technical volumes had notes entered in the margin boxes. The Professor was quite excited about the mathematical fragments, but more obviously, there were reminders to confide this or that thought or calculation to some names jotted next to them. Mostly members of the Waste Heat group, but also a couple of others, including one who appears to be one of the late members of the station-keeping crew at the soletta array. We're now positing that Radovas and his equipment, with inside help, had been smuggled up to the soletta for whatever it was they were trying to do, rather than being aboard the ore freighter. So was the soletta essential to what they were doing, or were they only using it for a test platform? ImpSec has agents out all over the planet today, questioning and requestioning colleagues, relatives, and friends of everyone on the soletta or having anything to do with their resupply shuttle. Tomorrow, I will get to read all those reports."
