Diplomatic Immunity (31 page)

"The ba's had over two hours to effect an escape. Surely it wouldn't
linger
 . . ." muttered Miles. But his voice lacked conviction. Roic, at least, caught the quaver at once; his helmet turned toward Miles, and he frowned.

They needed to count pressure suits, and check every lock to see if any of the vid monitors had been manually disabled. No, too slow—that would be a fine evidence-collecting task to delegate if one had the manpower, but Miles felt painfully bereft of minions just now. And in any case, so what if another suit was found to be gone? Pursuing loose suits was a job that the quaddies around the station were already turning to, by Venn's order. But if no other suit
was
gone . . . 

And Miles himself had just turned the
Idris
into a trap.

He gulped. "I was about to say, we need to count suits, but I've a better idea. I believe we should return to Nav and Com, and shut the ship down in sections from there. Collect all the weapons at our disposal, and do a systematic search."

Venn jerked around in his float chair. "What, do you think this Cetagandan agent could still be aboard?"

"M'lord," said Roic in an uncharacteristically sharp voice, "what t'matter with your
gloves
?"

Miles stared down, turning up his hands. His breath congealed in his chest. The thin, tough fabric of his biotainer gloves was shredding away, hanging loose in strings; beneath the lattice, his palms showed red. Their itching seemed to redouble. His breath let loose again in a snarl of "
Shit!
"

Venn bobbed closer, took in the damage with widening eyes, and recoiled.

Miles held his hands up, and apart. "Venn. Go collect Greenlaw and Leutwyn and take over Nav and Com. Secure yourselves and the infirmary, in that order. Roic. Go ahead of me to the infirmary. Open the doors for me." He choked back an unnecessary scream of
Run!
; Roic, with an indrawn breath audible over the suit com, was already moving.

He dodged through the half-dark ship in Roic's long-legged wake, touching nothing, expecting every lumping heartbeat to rupture inside him. Where had he collected this hellish contamination? Was anyone else affected? Everyone else?

No.
It had to have been the power-suit control joysticks. They'd slid greasily under his gloved hands. He had gripped them tighter, intent upon the task of bringing the suit back inboard. He'd taken the bait . . . Now, more than ever, he was certain the ba had walked an empty suit out the airlock. And then set a snare for any smartass who figured it out too soon.

He plunged through the door to the infirmary, past Roic, who stood aside, and straight on through the blue-lit inner door to the bio-sealed ward. A medtech's suited form jumped in surprise. Miles called up Channel 13 and rapped out, "Someone please . . ." then stopped. He'd meant to cry,
Turn on the water for me!
and hold his hands under the sluice of a sink, but where did the water then
go
? "Help," he finished in a smaller voice.

"What is it, my Lord Audi—" the chief surgeon began, stepping from the bathroom; then his glance took in Miles's upraised hands. "
What happened?
"

"I think I hit a booby trap. As soon as you have a free tech, have Armsman Roic take him down to Engineering and collect a sample from the repair suit remote controller there. It appears to have been painted with some powerful corrosive or enzyme and . . . and I don't know what else."

"Sonic scrubber," Captain Clogston snapped over his shoulder to the tech monitoring the makeshift lab bench. The man hastened to rummage among the stacks of supplies. He turned back, powering on the device; Miles held out both his burning hands. The machine roared as the tech ran the directed beam of vibration over the afflicted areas, its powerful vacuum sucking the loosened detritus both macroscopic and microscopic into the sealed collection bag. The surgeon leaned in with a scalpel and tongs, slicing and tearing away the remaining shreds of gloves, which were also sucked into the receptacle.

The scrubber seemed effective; Miles's hands stopped feeling worse, though they continued to throb. Was his skin breached? He brought his now-bare palms closer to his faceplate, impeding the surgeon, who hissed under his breath. Yes. Red flecks of blood welled in the creases of the swollen tissue.
Shit. Shit. Shit. . . . 
 

Clogston straightened and glanced around, lips drawn back in a grimace. "Your biotainer suit's compromised all to hell, my lord."

"There's another pair of gloves on the other suit," Miles pointed out. "I could cannibalize them."

"Not yet." Clogston hurried to slather Miles's hands with some mystery goo and wrap them in biotainer barriers, sealed to his wrists. It was like wearing mittens over handfuls of snot, but the burning pain eased. Across the room, the tech was scraping fragments of contaminated glove into an analyzer. Was the third man in with Bel? Was Bel still in the ice bath? Still alive?

Miles took a deep, steadying breath. "Do you have any kind of a diagnosis on Portmaster Thorne yet?"

"Oh, yes, it came up right away," said Clogston in a somewhat absent tone, still sealing the second wrist wrap. "The instant we ran the first blood sample through. What the hell we can
do
about it is not yet obvious, but I have some ideas." He straightened again, frowning deeply at Miles's hands. "The herm's blood and tissues are crawling with artificial—that is, bioengineered—parasites." He glanced up. "They appear to have an initial, latent, asymptomatic phase, where they multiply rapidly throughout the body. Then, at some point—possibly triggered by their own concentration—they switch over to producing two chemicals in different vesicles within their own cellular membrane. The vesicles engorge. A rise in the victim's body temperature triggers the bursting of the sacs, and the chemicals in turn undergo a violently exothermic reaction with each other—killing the parasite, damaging the host's surrounding tissues, and stimulating more nearby parasites to go off. Tiny, pin-point bombs all through the body. It's"—his tone went reluctantly admiring—"extremely elegant. In a hideous sort of way."

"Did—did my ice-water bath treatment help Thorne, then?"

"Yes, absolutely. The drop in core temperature stopped the cascade in its tracks, temporarily. The parasites had almost reached critical concentration."

Miles's eyes squeezed shut in brief gratitude. And opened again. "Temporarily?"

"I still haven't figured out how to get rid of the damned things. We're trying to modify a surgical shunt into a blood filter to both mechanically remove the parasites from the patient's bloodstream, and chill the blood to a controlled degree before returning it to the body. I think I can make the parasites respond selectively to an applied electrophoresis gradient across the shunt tube, and pull them right on out of the bloodstream."

"Won't that do it, then?"

Clogston shook his head. "It doesn't get the parasites lodged in other tissues, reservoirs of reinfection. It's not a cure, but it might buy time. I think. The cure must somehow kill every last one of the parasites in the body, or the process will just start up again." His lips twisted. "Internal vermicides could be tricky. Injecting something to kill already-engorged parasites within the tissues will just release their chemical loads. A very little of that micro-insult will play hell with circulation, overload repair processes, cause intense pain—it's . . . it's tricky."

"Destroy brain tissue?" Miles asked, feeling sick.

"Eventually. They don't seem to cross the blood-brain barrier very readily. I believe the victim would be conscious to a, um, very late phase of the dissolution."

"Oh." Miles tried to decide whether that would be good, or bad.

"On the bright side," offered the surgeon, "I may be able to downgrade the biocontamination alarm from Level Five to Level Three. The parasites appear to need direct blood-to-blood contact to effect transference. They don't seem to survive long outside a host."

"They can't travel through the air?"

Clogston hesitated. "Well, maybe not until the host starts coughing blood."

Until
, not
unless
. Miles noted the word choice. "I'm afraid talk of a downgrade is premature anyway. A Cetagandan agent armed with unknown bioweapons—well, unknown except for this one, which is getting too damned familiar—is still on the loose out there." He inhaled, carefully, and forced his voice to calm. "We've found some evidence suggesting that the agent still may be hiding aboard this ship. You need to secure your work zone from a possible intruder."

Captain Clogston cursed. "Hear that, boys?" he called to his techs over his suit com.

"Oh, great," came a disgusted reply. "Just what we need right now."

"Hey, at least it's something we can
shoot
," another voice remarked wistfully.

Ah, Barrayarans.
Miles's heart warmed. "On sight," he confirmed. These were
military
medicos; they all bore sidearms, bless them.

His eye flicked over the ward and the infirmary chamber beyond, summing weak points. Only one entry, but was that weakness or strength? The outer door was definitely the vantage to hold, protecting the ward beyond; Roic had taken up station there quite automatically. Yet traditional attack by stunner, plasma arc, or explosive grenade seemed . . . insufficiently imaginative. The place was still on ship's air circulation and ship's power, but this of all sections had to have its own emergency reservoirs of both.

The military-grade Level Five biotainer suits the medicos wore also doubled as pressure suits, their air circulation entirely internal. The same was not true of Miles's cheaper suit, even before he'd lost his gloves; his atmosphere pack drew air from the environs, through filters and cookers. In the event of a pressurization loss, his suit would turn into a stiff, unwieldy balloon, perhaps even rupture at a weak point. There were bod pod lockers on the walls, of course. Miles pictured being trapped in a bod pod while the action went on without him.

Given that he was already exposed to . . . whatever, peeling out of his biotainer suit long enough to get into something tighter couldn't make things any worse, could it? He stared at his hands and wondered why he wasn't dead yet. Could the glop he'd touched have been only a simple corrosive?

Miles clawed his stunner out of his thigh pocket, awkwardly with his mittened hand, and walked back through the blue bars of light marking the bio-barrier. "Roic. I want you to dash back down to Engineering and grab me the smallest pressure suit you can find. I'll guard this point till you get back."

"M'lord," Roic began in a tone of doubt.

"Keep your stunner out; watch your back. We're all here, so if you see anything move that isn't quaddie green, shoot first."

Roic swallowed manfully. "Yes, well, see that you
stay
here, m'lord. Don't go haring off on your own without me!"

"I wouldn't dream of it," Miles promised.

Roic departed at the gallop. Miles readjusted his awkward grip on the stunner, made sure it was set to maximum power, and took a stance partly sheltered by the door, staring up the central corridor at his bodyguard's retreating form. Scowling.

I don't understand this.

Something didn't add up, and if he could just get ten consecutive minutes not filled with lethal new tactical crises, maybe it would come to him. . . . He tried not to think about his stinging palms, and what ingenious microbial sneak assault might even now be stealing through his body, maybe even making its way into his brain.

An ordinary imperial servitor ba ought to have died before abandoning a charge like those haut-filled replicators. And even if this one had been trained as some sort of special agent, why spend all that critical time taking samples from the fetuses that it was about to desert or maybe even destroy? Every haut infant ever made had its DNA kept on file back in the central gene banks of the Star Crèche. They could make more, surely. What made
this
batch so irreplaceable?

His train of thought derailed itself as he imagined little gengineered parasites multiplying frenetically through his bloodstream,
blip-blip-blip-blip
.
Calm down, dammit.
He didn't actually know if he'd even been inoculated with the same evil disease as Bel.
Yeah, it might be something even worse
. Yet surely some Cetagandan designer neurotoxin—or even some quite ordinary off-the-shelf poison—ought to cut in much faster than this.
Although if it's a drug to drive the victim mad with paranoia, it's working really well.
Was the ba's repertoire of hell-potions limited? If it had any, why not many? Whatever stimulants or hypnotics it had used on Bel need not have been anything out of the ordinary, by the norms of covert ops. How many other fancy bio-tricks did it have up its sleeve? Was Miles about to personally demonstrate the next one?

Am I going to live long enough to say good-bye to Ekaterin?
A good-bye kiss was right out, unless they pressed their lips to opposite sides of some really thick window of glass. He had so much to say to her; it seemed impossible to find where to start. Even more impossible by voice alone, over an open, unsecured public com link.
Take care of the kids. Kiss them for me every night at bedtime, and tell them I loved them even if I never saw them. You won't be alone—my parents will help you. Tell my parents . . . tell them . . . 
 

Was this damned thing starting up already, or were the hot panic and choking tears in his throat entirely self-induced? An enemy that attacked you from the inside out—you could try to turn yourself inside out to fight it, but you wouldn't succeed—filthy weapon!
Open channel or not, I'm calling her now. . . . 
 

Instead, Venn's voice sounded in his ear. "Lord Vorkosigan, pick up Channel Twelve. Your Admiral Vorpatril wants you. Badly."

Miles hissed through his teeth and keyed his helmet com over. "Vorkosigan here."

"Vorkosigan, you idiot—!" The admiral's syntax had shed a few honorifics sometime in the past hour. "What the hell is going on over there? Why don't you answer your wrist com?"
