Barto cared about the future of Komarr, his widow had said. Might Radovas have been among the disaffected? And if he were, so what? Miles frowned in puzzlement as the car pulled into the stop in the station beneath the Terraforming Project offices.

As instructed, Tien Vorsoisson was waiting for them on the platform. He escorted them as before up through the atrium of his building to the floors of his domain; though a few doors were open on early morning activity in various departments as they passed, they were the first to arrive in Vorsoisson's office.

"Do you have any preference as to how to divide this up?" Miles asked Tuomonen, staring around meditatively as Vorsoisson brought up the lights.

"I managed to squeeze in a short interview with Andro Farr this morning," said Tuomonen. "He gave me some names of Marie Trogir's particular acquaintances at work. I believe I'd like to start with them."

"Good. If you want to start with Trogir, I'll start with Radovas, and we can meet in the middle. I want to begin by interviewing his boss, Soudha, I believe, Administrator Vorsoisson."

"Certainly, my Lord Auditor. Do you wish to use my office?"

"No, I think I want to see him in his own territory."

"I'll take you downstairs, then. I'll be at your disposal in just a moment, Captain Tuomonen."

Tuomonen seated himself at Vorsoisson's comconsole and eyed it thoughtfully. "Take your time, Administrator."

Vorsoisson, with a worried look over his shoulder, led Miles down one flight to the Department of Waste Heat Management. Soudha had not yet arrived; Miles dispatched Tien back to Tuomonen, then circled the engineer's office slowly, examining its decor and contents.

It was a rather bare place. Perhaps the department head had another, more occupied work area out at his experiment station. The book rack on the wall was sparsely filled, mostly with disks on management and technical references. There were works on space stations and their construction, to be sure close cousins of domes, but unlike Radovas's library, no more specialized texts on wormholes or five-space math than might be residue from Soudha's university days.

A heavy tread announced the room's owner; the curious look on Soudha's face to find his office open and lit as he entered gave way to understanding as he saw Miles.

"Ah. Good morning, Lord Auditor Vorkosigan."

"Good morning, Dr. Soudha." Miles replaced the handful of disks in their former slots.

Soudha looked a bit tired; perhaps he was not a morning person. He gave Miles a weary smile of greeting. "To what do I owe the honor of this visit?" He muffled a yawn, pulled a chair up near his desk, and gave Miles a gesture of invitation to it. "Can I get you some coffee?"

"No, thank you." Miles sat, and let Soudha settle himself behind his comconsole desk. "I have some unpleasant news." Soudha's face composed itself attentively. "Barto Radovas is dead." He watched for Soudha's response.

Soudha blinked, his lips parting in dismay. "That's a shock. I thought he was in good health, for his age. Was it his heart? Oh, my, poor Trogir."

"No one's health stands up to exposure to vacuum without a pressure suit, regardless of their age." Miles decided not to include the details of the corpse's massive trauma, for now. "His body was found in space."

Soudha glanced up, his brows rising. "Do they think it has some connection to the soletta accident, then?"

Or why else would Miles be taking an interest, right. "Perhaps."

"Have they—what about Marie Trogir?" Soudha's lips thinned thoughtfully. "You didn't say she . . . ?"

"She's not been found. Or not yet. The probable-cause crews are continuing search sweeps topside, and ImpSec is now looking everywhere else. Their next task, of course, is to try to trace the couple from the time and place they were last seen, which was several weeks ago and here, apparently. We'll be requesting the cooperation of your department, of course."

"Certainly. This is … this is really a very horrifying turn of events. I mean, regardless of one's opinion of the way they chose to pursue their personal choices …"

"And what is your opinion, Dr. Soudha? I'd really like to get a sense of the man, and of Trogir. Do you have any ideas?"

Soudha shook his head. "I confess, this turn in their relationship took me by surprise. But I don't pry into my employees' private lives."

"So you've said. But you worked closely with the man for five years. What were his outside interests, his politics, his hobbies, his obsessions?"

"I …" Soudha shrugged in frustration. "I can give you his complete work record. Radovas was a quiet sort of fellow, never made trouble, did first-rate technical work—"

"Yes, why did you hire him? Waste Heat Management does not appear to have been his previous specialty."

"Oh, he had a great deal of station expertise—as you may know, getting rid of excess heat topside is a standard engineering challenge. I thought his technical experience might bring some new perspectives to our problems, and I was right. I was very pleased with his work—Section Two of the reports I gave you yesterday was mostly his, if you would like to examine them to get a real sense of the man. Power generation and distribution. Hydraulics, in Section Three, was mostly mine. The basis of heat exchange through liquid transfer is most promising—"

"I've looked over your report, thanks."

Soudha looked startled. "All of it? I had really understood Dr. Vorthys would be wanting it. I'm afraid it's a bit thick on the technical detail."

Oh, sure, I speed-read all two hundred thousand words before bed last night. Miles smiled blandly. "I accept your evaluation of Dr. Radovas's technical competence. But if he was so good, why did he leave? Was he bored, happy, frustrated? Why did this change in his personal circumstances lead to change in his work? I don't see a necessary connection."

"For that," said Soudha, "I'm afraid you will have to ask Marie Trogir. I strongly suspect the driving force in this peculiar decision came from her, though they both resigned and left together. She had far less to lose, leaving here, in pay and seniority and status."

"Tell me more about her."

"Well, I truly can't. Barto hired her himself and worked with her on a daily basis. She barely came to my attention. Her technical ability appears to have been adequate—although, come to think of it, those evaluations were all supplied by Barto. I don't know." Soudha rubbed his forehead. "This is all pretty upsetting. Barto, dead. Why?" The distress in his voice seemed genuine to Miles's experienced ear, but his shock appeared more surprise than the deep grief from loss of a close friend; Miles would, perhaps, have to look elsewhere for the insights into Radovas he now sought.

"I'd like to examine Dr. Radovas's office and work areas."

"Oh. I'm afraid his office was cleared and reassigned."

"Have you replaced him?"

"Not yet. I'm still collecting applications. I hope to start interviewing soon."

"Radovas must have been friends with somebody. I want to speak with his coworkers."

"Of course, my Lord Auditor. When would you like me to set up appointments?"

"I thought I'd just drop in."

Soudha pursed his lips. "Several of my people are on vacation, and several more are out at the experiment station, running a small test this morning. I don't expect them to be done before dark. But I can get you started with the people here, and have some more in by the time you're done with the first."
