“I hear you,” said Vorpatril reluctantly. “But ma'am—the Imperial Auditor himself has been infected with one of the ba's lethal bio-agents. I cannot—I will not—if I have to sit here and do nothing while listening to him die—”

“There are fifty thousand innocent lives on Graf Station, Admiral—Lord Auditor!” Her voice failed for a second; returned stiffly. “I am sorry, Lord Vorkosigan.”

“I'm not dead yet,” Miles replied rather primly. A new and most unwelcome sensation struggled with the tight fear grinding in his belly. He added, “I'm going to switch off my com link for just a moment. I'll be right back.”

Motioning Roic to keep still, Miles opened the door to the security office, stepped into the corridor, opened his faceplate, leaned over, and vomited onto the floor. No help for it. With an angry swipe, he turned his suit temperature back up. He blinked back the green dizziness, wiped his mouth, went back inside, seated himself again, and called his link back on. “Continue.”

He let Vorpatril's and Greenlaw's arguing voices fade from his attention, and studied his view of Nav and Com more closely. One object had to be there, somewhere . . . ah. There it was, a small, valise-sized cryo-freezer case, set carefully down next to one of the empty station chairs near the door. A standard commercial model, no doubt bought off the shelf from some medical supplier here on Graf Station sometime in the past few days. All of this , this entire diplomatic mess, this extravagant trail of deaths winding across half the Nexus, two empires teetering on the verge of war, came down to that . Miles was reminded of the old Barrayaran folktale, about the evil mutant magician who kept his heart in a box to hide it from his enemies.

Yes . . .

“Greenlaw,” Miles broke in. “Do you have any way to signal back to Corbeau?”

“We designated one of the navigation buoys that broadcasts to the channels of the pilots on cyber-neuro control. We can't get voice communication through it—Corbeau wasn't sure how it would emerge, in his perceptions. We are certain we can get some kind of simple code blink or beep through it.”

“I have a simple message for him. Urgent. Get it through if you possibly can, however you can. Tell him to open all the inner airseal doors in the middle deck of the central nacelle. Kill the security vids there, too, if he can.”

“Why?” she asked suspiciously.

“We have personnel trapped there who are going to die shortly if he doesn't,” Miles replied glibly. Well, it was true.

“Right,” she rapped back. “I'll see what we can do.”

He cut his outgoing voice link, turned in his station chair, and made a throat-cutting motion for Roic to do the same. He leaned forward. “Can you hear me?”

“Yes, m'lord.” Roic's voice was muffled, through the work suit's thicker faceplate, but sufficiently audible; they neither of them had to shout, in this quiet, little space.

“Greenlaw will never order or permit a strike force to be launched to try to capture the ba. Not hers, not ours. She can't. There are too many quaddie lives up for grabs. Trouble is, I don't think this placating approach will make her station any safer. If this ba really murdered a planetary consort, it'll not even blink at a few thousand quaddies. It'll promise cooperation right up to the last, then hit the release switch on its bio-bomb and jump, just for the off chance that the chaos in its wake will delay or disrupt pursuit an extra day or three. Are you with me so far?”

“Yes, m'lord.” Roic's eyes were wide.

“If we can get as close as the door to Nav and Com unseen, I think we have a chance of jumping the ba ourselves. Specifically, you will jump the ba; I will supply a distraction. You'll be all right. Stunner and nerve disruptor fire will pretty much bounce off that work suit. Needler spines wouldn't penetrate immediately either, if it comes to that. And it would take longer than the seconds you'll need to cross that little room for plasma arc fire to burn through it.”

Roic's lips twisted. “What if he just fires at you? That pressure suit's notthat good.”

“The ba won't fire at me. That, I promise you. The Cetagandan haut, and their siblings the ba, are physically stronger than anyone but the dedicated heavy-worlders, but they're not stronger than a power suit. Go for his hands. Hold them. If we get that far, well, the rest will follow.”

“And Corbeau? The poor bastard's starkers. Nothing's gonna stop anything fired at him.”

“Corbeau,” said Miles, “will be the ba's last choice of targets. Ah!” His eyes widened, and he whirled about in his station chair. At the edge of the vid image, half a dozen tiny images in the array were quietly going dark. “Get to the corridor. Get ready to run. As silently as you can.”

From his com link, Vorpatril's volume-reduced voice pleaded heartrendingly for the Imperial Auditor to please reopen his outgoing voice contact. He urged Lady Vorkosigan to request the same.

“Leave him alone,” Ekaterin said firmly. “He knows what he's doing.”

“What is he doing?” Vorpatril wailed.

“Something.” Her voice fell to a whisper. Or perhaps it was a prayer. “Good luck, love.”

Another voice, somewhat offsides, broke in: Captain Clogston. “Admiral? Can you reach Lord Auditor Vorkosigan? We've finished preparing his blood filter and are ready to try it, but he's disappeared out of the infirmary. He was right here a few minutes ago . . .”

“Do you hear that, Lord Vorkosigan?” Vorpatril tried somewhat desperately. “You are to report to the infirmary. Now.”

In ten minutes—five—the medics could have their way with him. Miles pushed up from his station chair—he had to use both hands—and followed Roic into the corridor outside Solian's office.

Up ahead in the dimness, the first airseal door across the corridor hissed quietly aside, revealing the cross-corridor to the other nacelles beyond. On the far side, the next door began to slide.

Roic started trotting. His steps were unavoidably heavy. Miles half-jogged behind. He tried to think how recently he had used his seizure-stimulator, how much at risk he was right now for falling down in a fit from a combination of bad brain chemistry and terror. Middling risky, he decided. No automatic weapons for him this trip anyway. No weapons at all, but for his wits. They seemed a meager arsenal, just at the moment.

The second pair of doors opened for them. Then the third. Miles prayed they were not walking into another clever trap. But he didn't think the ba would have any way of tapping, or even guessing, this oblique line of communication. Roic paused briefly, stepping behind the last door edge, and peered ahead. The door to Nav and Com was shut. He gave a short nod and continued forward, Miles in his shadow. As they drew closer, Miles could see that the control panel to the left of the door had been burned out by some cutting tool, cousin, no doubt, to the one Roic had used. The ba had gone shopping in Engineering, too. Miles pointed at it; Roic's face lightened, and a corner of his mouth turned up. Someone hadn't forgotten to lock the door behind them when they'd last left after all, it appeared.

Roic pointed to himself, to the door; Miles shook his head and motioned him to bend closer. They touched helmets.

“Me first. Gotta grab that case before the ba can react. 'Sides, I need you to pull back the door.”

Roic looked around, inhaled, and nodded.

Miles motioned him back down to touch helmets one more time. “And, Roic? I'm glad I didn't bring Jankowski.”

Roic smiled. Miles stepped aside.

Now. Delay was no one's friend.

Roic bent, splayed his gloved hands across the door, pressed, and pulled. The servos in his suit whined at the load. The door creaked unwillingly aside.

Miles slipped through. He didn't look back, or up. His world had narrowed to one goal, one object. The freezer case—there, still on the floor beside the absent communication officer's station chair. He pounced, grabbed, lifted it up, clutched it to his chest like a shield, like the hope of his heart.
