Miles clenched his fists and jerked against his chains. Foscol glanced at him and added kindly, 'Don't hurt yourself, trying to get loose. Someone will be along eventually to collect you. I only regret I won't be able to watch.' She turned on her heel and strode away, down the walk and around the corner of the building. After another minute, the faint sounds of a lift-van taking to the air drifted around the building. But they were on the opposite side of the building to the approach from Serifosa, and the departing van did not cross into Miles's limited line of sight.
Their next-of-kin, however . . . Miles thought of his father and shuddered. And Ekaterin and Nikolai, and, of course, Lord Auditor Vorthys. Oh, yes.
Vorsoisson, coming to full consciousness at last, reared up and discovered the limits of his bonds. He swore muzzily, then with increasing clarity of expression, and yanked his arms against their chains. After about a minute, he stopped. He stared around and found Miles.
'Vorkosigan. What the hell is going on here?'
'We appear to have been parked out of the way while Soudha and his friends finish decamping from the experiment station. They seem to have realized their time had run out.' Miles wondered if he ought to mention to Vorsoisson what was taped to his back, then decided against it. The man was already breathing heavily from his struggles. Vorsoisson swore some more, monotonously, but after a bit seemed to become aware that he was repeating himself, and ran down.
'Tell me more about this embezzlement scheme of Soudha's,' Miles said into the eerie silence. No insect or bird chirps enlivened the Komarran night, and no tree leaves rustled in the faint, chill breeze. No further sounds came from the buildings behind them. The only noise was the susurration of their breath masks' powered fans, filters, and regulators. 'When did you find out about it?'
'Just . . . yesterday. A week ago yesterday. Soudha panicked, I think, and tried to bribe me. I didn't want to embarrass Kat's Uncle Vorthys by blowing it wide open while he was here. And I had to be sure, before I started accusing people right and left.'
Miles simultaneously sympathized with and was deeply suspicious of Vorsoisson's claimed hesitation, a dizzying state of mind to endure on top of a stunner migraine. He had never thought of fast-penta as a medicine for headache, but he wished he had a hypospray of it to jab in Vorsoisson's ass right now.
'What do you mean, all?'
'I don't quite … if I were Soudha and his group, fleeing the scene of our crime . . . they did have some lead time to prepare their retreat. Maybe as long as three or four weeks, if they knew Radovas's body was likely to be found topside.'
Vorsoisson shook his head, which shifted his breath mask slightly; he had to rub his face against the railing to reseat it. After a few minutes he said in a small voice, 'Vorkosigan . . . ?'
Miles hoped from the humbler tone the man might be going to edge toward true confession after all. 'Yes?' he said encouragingly.
'I'm almost out of oxygen.'
'Didn't you check—' Miles tried to bring up the image in his pulsing brain of the moment Vorsoisson had snatched his breath mask out of the cabinet, back in his office, and donned it. No. He hadn't checked anything about it. A fully-charged mask would support twelve to fourteen hours of vigorous outdoor activity, under normal circumstances. Miles's visitor's mask had presumably been taken from a central store, where some tech had the job of processing and recharging used masks before setting them on the rack ready for reuse. Don't
At one time, Miles could have crushed his own fragile hand bones and drawn his hand out through a restraint before his flesh began to swell enough to trap it again. He'd actually done that once, on a hideously memorable occasion. But the bones in his hands were all sturdy synthetics now, less breakable even than normal bone. All that his applied strength could do was make his chafed wrists bleed.
Vorsoisson's wrists began to bleed too, as he struggled more frantically against his chains.
'Vorsoisson, hold still!' Miles called urgently to him. 'Conserve your oxygen. There's supposed to be someone coming. Go limp, breathe shallowly, make it last.' Why hadn't the idiot mentioned this earlier, to Miles, to
Vorsoisson wriggled his chin and tried to peer down over his nose into the dim recesses of his jacket to see the top of the canister strapped there. 'Oh, God. I think it's reading zero.'
'Those things always have some safety margin. Stay still, man! Try for some self-control!'
Instead Vorsoisson began to struggle ever more frantically. He threw himself forward and backward with all his considerable strength, trying to break the railing. Blood drops flew from the flayed skin of his wrists, and the railing reverberated and bent, but it did not break. He pulled up his knees and then flung himself down through the meter-wide opening between the posts, trying to propel his full body weight against the chains. They held, and then his backward-scrambling legs could not regain the walkway. His boot heels scraped and scrabbled on the wall. His dizzied choking, at the last, led to vomiting inside his breath mask. When it slipped down around his neck in his final paroxysms, it seemed almost a mercy, except for the way it revealed his distorted, purpling features. But the screams and pleas stopped, and then the gasps and gulpings. The kicking legs twitched, and hung limply.
Miles had been right; Vorsoisson might have had a full twenty or thirty minutes more oxygen if he had hunkered down quietly. Miles stood very still, and breathed very shallowly, and shivered in the cold. Shivering, he recalled dimly, used more oxygen, but he could not make himself stop. The silence was profound, broken only by the hiss of Miles's regulators and filters, and the beating of the blood in his own ears. He had seen many deaths, including his own, but this was surely one of the ugliest. The shocky shudders traveled up and down his body, and his thoughts spun uselessly: they kept circling back to the spuriously calm observation that a barrel of fast-penta would be no damned use to him now.
If he went into a convulsion and dislodged his breath mask in the process, he could be well on his way to asphyxiating before he even returned to consciousness. ImpSec would find him hanging there beside Vorsoisson, choked identically on his own spew. And nothing was more likely to set off one of his seizures than stress.
Miles watched the slime begin to freeze on the sagging corpse's face, scanned the dark skies in the wrong direction, and waited.
