He'll be waiting for you outside on the northwest side. . . . She had only a vague idea which side of the building was the northwest; she'd half-expected Tien to be waiting in the parking lot. She sighed uneasily, and adjusted her breath mask again, and stepped out through the pedestrian lock. It would only take a few minutes to circle the building. I want to fly back to Serifosa, right now. This is weird. Slowly, she started around the building to her left, her footsteps sounding sharp on the concrete in the chill and toxic night air. A raised walkway, really the level edge of the building's concrete foundation, skirted the wall, with a railing along the outside as the ground fell away below. It made her feel as though she were being herded into some trap, or a corral. She rounded the second corner.

Halfway down the walk, a small human shape huddled on its knees, arms outflung, its forehead pressed against the railing. Another bigger shape hung by its wrists between two wide-spaced posts, its body dangling down over the edge of the raised concrete foundation, feet a half-meter from the ground. What is this? The dark seemed to pulsate. She swallowed her panic and hastened toward the odd pair.

The dangling figure was Tien. His breath mask was off, twisted around his neck. Even in the colored half-light from the spots in the vegetation below, she could see his face was mottled and purple, with a cold doughy stillness. His tongue protruded from his mouth; his bulging eyes were fixed and frozen. Very, very dead. Her stomach churned and knotted in shock, and her heart lumped in her chest.

The kneeling figure was Lord Vorkosigan, wearing her second-best jacket that she had been unable to find while packing a short eternity ago. His breath mask was still up—he turned his head, his eyes going wide and dark as he saw her, and Ekaterin melted with relief. The little Lord Auditor was still alive, at least. She was frantically grateful not to be alone with two corpses. His wrists, she saw at last, were chained to the railing's posts just as Tien's were. Blood oozed from them, soaking darkly into the jacket's cuffs.

Her first coherent thought was unutterable relief that she had not brought Nikki with her. How am I going to tell him? Tomorrow, that was a problem for tomorrow. Let him play away tonight in the bubble of another universe, one without this horror in it.

"Madame Vorsoisson." Lord Vorkosigan's voice was muffled and faint in his breath mask. "Oh, God."

Fearfully, she touched the cold chains around his wrists. The torn flesh was swollen up around the links, almost burying them. "I'll go inside and look for some cutters." She almost added, Wait here, but closed her lips on that inanity just in time.

"No, wait," he gasped. "Don't leave me alone—there's a key . . . supposedly … on the walk back there." He jerked his head.

She found it at once, a simple mechanical type. It was cold, a slip of metal in her shaking fingers. She had to try several times to get it inserted in the locks that fastened the chains. She then had to peel the chain out of Vorkosigan's blood-crusted flesh as if from a rubber mold, before his hand could fall. When she released the second one, he nearly pitched headfirst over the edge of the concrete. She grabbed him and dragged him back toward the wall. He tried to stand, but his legs would not at first unbend, and he fell over again. "Give yourself a minute," she told him. Awkwardly, she tried to massage his legs, to restore circulation; even through the fabric of his gray trousers she could feel how cold and stiff they were.

She stood, holding the key in her hand, and stared in bewilderment at Tien's body. She doubted she and Vorkosigan together could lift that dead weight back up to the walk.

"It's much too late," said Vorkosigan, watching her. His brows were crooked with concern. "I'm s-sorry. Leave him for Tuomonen."

"What is this on his back?" She touched the peculiar arrangement, what appeared to be a plastic packet fixed in place with engineering tape.

"Leave that," said Lord Vorkosigan more sharply. "Please." And then, in more of a rush, stuttering in his shivering, "I'm sorry. I'm sorry. I c-couldn't b-break the chains. Hell, he couldn't either, and he's s-stronger than I am. … I thought I c-could break my hand and get it out, but I couldn't. I'm sorry. …"

"You need to come inside, where it's warm. Here." She helped pull him to his feet; with a last look over his shoulder at Tien, he suffered himself to be led, hunched over, leaning on her and lurching on his unsteady legs.

She led him through the airlock into the office building, and guided him to an upholstered chair in the lobby. He more fell than sat in it. He shivered violently. "B-b-button," he muttered to her, holding up his hands like paralyzed paws toward her.

"What?"

"Little button on the s-side of wrist-comm. Press it!"

She did so; he sighed and relaxed against the seat back. His stiff hands yanked at his breath mask; she helped him pull it off over his head, and pulled down her own mask.

"God I am glad to get out of that thing. Alive. I th-thought I was gonna have a seizure out there. . . ."He rubbed his pale face, scrubbing at the red pressure-lines engraved in the skin from the edges of the mask. "And it itched." Ekaterin spotted the control on a nearby wall and hastily tapped in an increase of the lobby's temperature. She was shivering too, though not from the cold, in suppressed shocky shudders.

"Lord Vorkosigan?" Captain Tuomonen's anxious voice issued thinly from the wrist com. "What's going on? Where the hell are you?!"

Vorkosigan lifted his wrist toward his mouth. "Waste Heat experiment station. Get out here. I need you."

"What are you– Should I bring a squad?"

"Don't need guns now, I don't think. You'll need forensics, though. And a medical team."

"Are you injured, my lord?" Tuomonen's voice grew sharp with panic.

"Not to speak of," he said, apparently oblivious to the blood still leaking from his wrists. "Administrator Vorsoisson is dead, though."

"What the hell—you didn't check in with me before you left the dome, dammit! What the hell is going on out there?!"

"We can discuss my failings at length, later. Carry on, Captain. Vorkosigan out." He let his arm fall, wearily. His shivering was lessening, now. He leaned his head back against the upholstery; the dark smudges of exhaustion under his eyes looked like bruises. He stared sadly at Ekaterin. "I am sorry, Madame Vorsoisson. There was nothing I could do."

"I would scarcely think so!"

He looked around, squinting, and added abruptly, "Power plant!"

"What about it?" asked Ekaterin.

"Gotta check before the troops arrive. I spent a lot of time wondering if it might have been sabotaged, when I was tied up out there."

His legs were still not working right. He almost fell over again as he tried to turn on his heel; she rose and just caught him, under his elbow.

"Good," he said vaguely to her, and pointed. "That way."

She was evidently drafted as support. He hobbled off in determination, clinging to her arm without apology. The forced action actually helped her to recover, if not calm, a sort of tenuous physical coherence; her shudders damped out, and her incipient nausea passed, leaving her belly feeling hot and odd. Another pedestrian tube led down to the power plant, next to the river. The river was the largest in the Sector, and the proximate reason for siting the experiment station here. By Barrayaran standards it would have been called a creek. Vorkosigan barged awkwardly around the power plant's control room, examining panels and readouts. "Nothing looks abnormal," he muttered. "I wonder why they didn't set it to self-destruct? I would have. . . ." He fell into a station chair. She pulled up another one, and sat opposite him, watching him fearfully. "What happened!"
