Diplomatic Immunity

by Lois McMaster Bujold

  No bio-plague can cross that gap, he thought with satisfaction, then instantly thought of what the Cetagandans might do with spores. I hope.

  It occurred to him belatedly that if the Prince Xav's surgeon sounded an all-clear from the biocontamination alert, docking once again was going to be a critically more delicate task. Well, if he clears the ship, we can import a pilot then. He glanced at the time on a wall digital. Barely an hour had passed since they'd found Bel. It seemed a century.

  "You're a pilot, as well?" a surprised, muffled female voice sounded.

  Miles swung around in the pilot's chair to find the three quaddies in their floaters hovering in the control room's doorway. All now wore quaddie-shaped biotainer suits in pale medical green. His eye rapidly sorted them out. Venn was bulkier, Sealer Greenlaw a little shorter. Adjudicator Leutwyn brought up the rear.

  "Only in an emergency," he admitted. "Where did you get the suits?"

  "My people sent them across from the station in a drone pod," said Venn. He, too, wore his stunner holstered on the outside of his suit.

  Miles would have preferred to keep the civilians safely locked down in the freight nacelle, but there was clearly no help for that now.

  "Which is still attached to the lock, yes," Venn overrode Miles's opening mouth.

  "Thank you," said Miles meekly.

  He wanted desperately to rub his face and scrub his itching eyes, but couldn't. What was next? Had he done all he could to contain this thing? His eye fell on the decontaminator, slung over Roic's shoulder. It would probably be a good idea to take that back down to Engineering and sterilize their tracks.

  "M'lord?' said Roic diffidently.

  "Yes, Armsman?"

  "I been thinking. The night guard saw the portmaster and the ba enter the ship, but nobody reported anybody leaving. We found Thorne. I was wondering how the ba got off the ship."

  "Thank you, Roic, yes. And how long ago. Good question to pursue next."

  "Whenever one of the Idris's hatches opens, its lock vid recorders start up automatically. We should ought to be able to access t'lock records from here, I'd think, same as from Solian's security office." Roic cast a somewhat desperate eye around the intimidating array of stations. "Somewhere."

  "We should indeed." Miles abandoned the pilot's chair for the flight engineer's station. A little poking among the controls, and a short delay while one of Roic's library of override codes pacified the lockdowns, and Miles was able to bring up a duplicate file of the sort of airlock security records they'd found in Solian's office and spent so many bleary-eyed hours studying. He set the search to present the data in reverse order of time.

  The most recent usage was first up on the vid plate, a nice shot of the automated drone pod docking at the outboard personnel lock serving the number two freight nacelle. An anxious-looking Venn scooted into the lock in his floater. He shuttled in and out handing back green suits folded in plastic bags to waiting hands, plus an assortment of other objects: a big box of first aid supplies, a tool kit, a decontaminator somewhat resembling Roic's, and what might be some weapons with rather more authority than stunners. Miles cut the scene short and sent the search back in time.

  Mere minutes before that was the Barrayaran military medical patrol arriving in a small shuttle from the Prince Xav, entering via one of the number four nacelle personnel locks. The three medical officers and Roic were all clearly identifiable, hastily unloading equipment.

  A freight lock in one of the Necklin drive nacelles popped up next, and Miles caught his breath. A figure in a bulky extravehicular-repairs suit marked with serial numbers from the Idris's engineering section lumbered heavily past the vid pickup, and departed into the vacuum with a brief puff of suit jets. The quaddies bobbing at Miles's shoulder murmured and pointed; Greenlaw muffled an exclamation, and Venn choked on a curse.

  The next record back in time was of themselves—the three quaddies, Miles, and Roic—entering the ship from the loading bay for their inspection, however many hours ago it had been. Miles tapped instantly back to the mystery figure in the engineering suit. What time . . . ?

  Roic exclaimed, "Look, m'lord! He—it—was getting away not twenty minutes before we found t'portmaster! The ba must've still been aboard when we came on!" Even through his faceplate, his face took on a greenish tinge.

  Had Bel's conundrum in the bod pod been a fiendishly engineered delaying tactic? Miles wondered if the knotted feeling in his stomach and tightness in his throat could be the first sign of a bioengineered plague. . . .

  "Is that our suspect?" asked Leutwyn anxiously. "Where did he go?"

  "What is the range on those heavy suits of yours, do you know, Lord Auditor?" asked Venn urgently.

  "Those? Not sure. They're meant to allow men to work outside the ship for hours at a time, so I'd guess, if they were fully topped up with oxygen, propellant, and power . . . damned near the range of a small personnel pod." The engineering repair suits resembled military space armor, except with an array of built-in tools instead of built-in weapons. Too heavy for even a strong man to walk in, they were fully powered. The ba might have ridden in one around to any point on Graf Station. Worse, the ba might have ridden out to a mid-space pickup by some Cetagandan co-agent, or perhaps by some bribed or simply bamboozled local helper. The ba might be thousands of kilometers away by now, with the gap widening every second. Heading for entry to another quaddie habitat under yet another faked identity, or even for rendezvous with a passing jumpship and escape from Quaddiespace altogether.

  "Station Security is on full emergency alert," said Venn. "I have all my patrollers and all of the Sealer's militia on duty out looking for the fellow—the person. Dubauer can't have gotten back aboard the station unobserved." A tremor of doubt in Venn's voice undercut the certainty of this statement.

  "I've ordered the station onto a full biocontamination quarantine," said Greenlaw. "All incoming ships and vehicles have been waved off or diverted to Union, and none now in dock are cleared to leave. If the fugitive did get back aboard already—it isn't leaving." Judging by the sealer's congealed expression, she was by no means sure if this was a good thing. Miles sympathized. Fifty thousand potential hostages . . . "If it's fled somewhere else . . . if our people can't locate this fugitive promptly, I'm going to have to extend the quarantine throughout Quaddiespace."

  What would be the most important task for the ba, now that the flag had been dropped? It had to realize that the tight secrecy it had relied on for protection thus far was irremediably ruptured. Did it realize how close on its heels its pursuers had come? Would it still wish to murder Gupta to assure the Jacksonian smuggler's silence? Or would it abandon that hunt, cut losses, and run if it could? Which direction was it trying to move, back in, or out?

  Miles's eye fell on the vid image of the work suit, frozen above the plate. Did that suit have the kind of telemetry space armor did? More to the point—did it have the kind of remote control overrides some space armor did?

  "Roic! When you were down in the engineering suit lockers hunting for that pressure suit, did you see an automated command-and-control station for these powered repair units?"

  "I . . . there's a control room down there, yes, m'lord. I passed it. I don't know what all might be in it."

  "I have an idea. Follow me."

  He levered himself from the station chair and left Nav and Com at a sloppy jog, his biotainer suit sliding aggravatingly around him. Roic strode after; the curious quaddies followed in their floaters.

  The control room was scarcely more than a booth, but it featured a telemetry station for exterior maintenance and repairs. Miles slid into its station chair, and cursed the tall person who'd fixed it at a height that left his boots dangling in air. On permanent display were several real-time vid shots of critical portions of the ship's outlying anatomy, including directional antenna arrays, the mass shield generator, and the main normal-space thrusters. Miles sorted through a bewildering mess of data from structural safe
ty sensors scattered throughout the ship. Finally, the work suit control program came up.

  Six suits in the array. Miles called up visual telemetry from their helmet vids. Five returned views of blank walls, the insides of their respective storage lockers. The sixth returned a lighter image, but more puzzling, of a curving wall. It remained as static as the vistas from the suits in storage.

  Miles pinged the suit for full telemetry download. The suit was powered up but quiescent. The medical sensors were basic, just heart rate and respiration—and turned off. The life-support readouts claimed the rebreather was fully functional, the interior humidity and temperature were exactly on-spec, but the system appeared to be supporting no load.

  "It can't be very far away," Miles said over his shoulder to his hovering audience. "There's zero time lag in my com linkup."

  "That's a relief," sighed Greenlaw.

  "Is it?" muttered Leutwyn. "Who for?"

  Miles stretched shoulders aching with tension, and bent again to the displays. The powered suit had to have an exterior control override somewhere; it was a common safety feature on these civilian models, in case its occupant should suddenly become injured, ill, or incapacitated . . . ah. There.

  "What are you doing, m'lord?" asked Roic uneasily.

  "I believe I can take control of the suit via the emergency overrides, and bring it back aboard."

  "Wit' t' ba inside? Is that a good idea?"

  "We'll know in a moment."

  He gripped the joysticks, slippery under his gloves, gained control of the suit's jets, and tried a gentle puff. The suit slowly began to move, scraping along the wall and then turning away. The puzzling view resolved itself—he was looking at the outside of the Idris itself. The suit had been hidden, tucked in the angle between two nacelles. No one inside the suit fought back at this hijacking. A new and extremely disturbing thought crept up on Miles.

  Carefully, Miles brought the suit back around the outside of the ship to the nearest lock to Engineering, on the outboard side of one of the Necklin rod nacelles, the same lock from which it had exited. Opened the lock, brought the suit inside. Its servos kept it upright. The light reflected from its faceplate, concealing whatever was within. Miles did not open the interior lock door.

  "Now what?" he said to the room at large.

  Venn glanced at Roic. "Your armsman and I have stunners, I believe. If you control the suit, you control the prisoner's movements. Bring it in, and we'll arrest the bastard."

  "The suit has manual capacities, too. Anyone in it who was . . . alive and conscious should have been able to fight me." Miles cleared a throat thick with worry. "I was just wondering if Brun's searchers checked inside these suits when they were looking for Solian, that first day he went missing. And, um . . . what he's like—what condition his body might be in by now."

  Roic made a small noise, and emitted an undervoiced, plaintive protest of M'lord! Miles wasn't sure of the exact interpretation, but he thought it might have something to do with Roic wanting to keep his last meal in his stomach, and not all over the inside of his helmet.

  After a brief, fraught pause, Venn said, "Then we'd better go have a look. Sealer, Adjudicator—wait here."

  The two senior officials didn't argue.

  "Would you like to stay with 'em, m'lord?" Roic suggested tentatively.

  "We've all been looking for that poor bastard for weeks," Miles replied firmly. "If this is him, I want to be the first to know." He did allow Roic and Venn to precede him from engineering through the locks into the Necklin field generator nacelle, though.

  At the lock, Venn drew his stunner and took position. Roic peered through the port on the airlock's inner door. Then his hand swept down to the lock control, the door slid open, and he strode in. He reappeared a moment later, half-dragging the heavy toppling work suit. He laid it faceup on the corridor floor.

  Miles ventured closer and stared down at the faceplate.

  The suit was empty.

  CHAPTER FIFTEEN

  "Don't open it!" cried Venn in alarm.

  "Wasn't planning to," Miles replied mildly. Not for any money.

  Venn floated closer, stared down over Miles's shoulder, and swore. "The bastard's got away already! But to the station, or to a ship?" He edged back, tucked his stunner away in a pocket of his green suit, and began to gabble into his helmet com, alerting both Station Security and the quaddie militia to pursue, seize, and search anything—ship, pod, or shuttle—that had so much as shifted its parking zone off the side of the station in the past three hours.

  Miles envisioned the escape. Might the ba have ridden the repairs suit back aboard the station before Greenlaw had called down the quarantine? Yes, maybe. The time window was narrow, but possible. But in that case, how had it returned the suit to the hiding place outside the Idris? It would make more sense for the ba to have been picked up by a personnel pod—plenty enough of them zipping around out there at all hours—and have prodded the suit back to its concealment with a tractor beam, or had it towed there by someone in another powered suit and tucked out of sight.

  But the Idris, like all the other Barrayaran and Komarran ships, was under surveillance by the quaddie militia. How cursory was that outside guard? Surely not that inattentive. Yet a person, a tall person, sitting in that engineering control booth manipulating the joysticks, might well have walked the suit out this airlock and quickly around the nacelle, popping it away out of sight deftly enough to evade notice by the militia guardians. Then risen from the station chair, and . . . ?

  Miles's palms itched, maddeningly, inside his gloves, and he rubbed them together in a futile attempt to gain relief. He'd have traded blood for the chance to rub his nose. "Roic," he said slowly. "Do you remember what this," he prodded the repair suit with his toe, "had in its hand when it went out the airlock?"

  "Um . . . nothing, m'lord." Roic twisted slightly and shot Miles a puzzled look, through his faceplate.

  "That's what I thought." Right.

  If Miles was guessing correctly, the ba had turned aside from the imminent murder of Gupta to seize the chance of using Bel to get back aboard the Idris and do—what?—with its cargo. Destroy it? It would surely not have taken the ba this long to inoculate the replicators with some suitable poison. It might even have been able to do them twenty at a time, introducing the contaminant into the support system of each rack. Or—even more simply, if all it had wanted was to kill its charges—it might have just turned off all the support systems, a work of mere minutes. But taking and marking individual cell samples for freezing, yes, that could well have taken all night, and all day too. If the ba had risked everything to do that, would it then leave the ship without its freezer case firmly in hand?

  "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 o
f 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.
