Still, there were extenuating circumstances, he supposed. This business of insinuating himself into human brains wasn't quite as straightforward as he'd assumed it would be, though it didn't occur to him that only his own arrogance had suggested that it would be simple.

  The inert lump of flesh on his deck had been terrified when a trio of silent, metallic shapes invaded its isolated radar post, but it had tried. The Troll had to allow the captain that much—it had tried. It had called frantically for assistance, but the Troll's mechanical minions had jammed all its communication circuits even before they crossed the post's perimeter and butchered the paratroopers assigned to provide security. The captain and its men had rushed out of the command trailer, and it had emptied its Browning automatic into one of the combat mechs at point-blank range. In fact, it had actually reloaded with trembling fingers and emptied its weapon a second time in the moments the war machines took to slaughter its small team of technicians, but its pistol had been as futile as the paras' assault rifles.

  The uselessness of its weapons in the face of the otherworldly attack had replaced fear with horror and panic at last . . . or perhaps it had been the realization that it alone survived. It had turned to flee, but the IR systems of the combat mechs had picked it out of the darkness like a glowing beacon. In part, the Troll blamed himself for what had happened after that, but he'd been unable to resist the pleasure of drawing out the pursuit until the madly fleeing human collapsed in sweating, whimpering terror in the clammy fog. Only then had the combat mech closed in with the capture field and carried the twitching body away while its companions piled the dead in and around the trailer and set it afire.

  The flames had arced into the heavens, turning droplets of fog into glittering tears of blood and gold, as the soulless mechanisms withdrew. Secondary explosions of generator fuel and ammunition had disemboweled the trailer, dismembering and scattering the victims' bodies, and the Troll had been content. He had his specimen, and even if he didn't understand the tensions which afflicted the region, he had observed enough to know there were two sides in conflict. He felt confident the side he had attacked would blame the other for it.

  But Captain Santiago had proven a frustratingly imperfect prize. The Troll was fairly certain the human had begun to crack even before it recovered consciousness within the hidden fighter, but its mind had collapsed completely under the defilement and physical agony of his clumsy invasion. The Troll's grasping mental tendrils had time to snatch only the most jumbled of gestalts from the crumbling ruin before it lapsed into merciful catatonia, and nothing he'd tried had been able to drag it back from the escape of its self-imposed non-thought.

  The Troll snarled a mental curse and summoned a combat mech. The machine whirred in on the big, low-pressure tires it used for ground movement and lifted the fetal curl of flesh in tireless arms. The Troll left the machine to its autonomous programming, too frustrated with his own clumsiness to find his usual pleasure in observing the death of a human, however mad, as the mech carried the captain outside and killed it.

  The interior lighting fell to its normal, feeble levels, and the Troll considered the fragmentary information he'd gleaned. He had only a vague notion of who these "British" enemies of the captain were, but he had learned enough to be disinterested in them. He had, however, been surprised by how few nuclear-armed power blocs there were on this planet—surely that indicated an even cruder level of technology than he had anticipated? But it seemed that the only true so-called superpower lay further to the north on this same land mass. That was interesting. And it had an elective form of government. That was even more interesting.

  The combat mech returned from its task, leaving behind a smoking pit containing a few ashy flakes of Captain Hector Santiago y Santos, Feurza Aerea Argentina. The hatch closed behind it, and four hundred feet of night-black silence rose into the dripping night with less sound than an indrawn breath. It skirted the southern slopes of La Meseta de las Vizcachas and dipped down into the valleys of the Andes, moving slowly and steadily north.

  CHAPTER FOURTEEN

  The US Navy CH-53E Super Stallion hovered above the helipad on USS McKee's afterdeck, navigation lights twinkling as it sank slowly onto the brightly lit landing circle, and Mordecai Morris made himself sit motionless in its red-lit, noisy belly by sheer force of will.

  He turned his head and smiled at Jayne Hastings. Did he look as unnatural in his flight suit and helmet as she did? He was certain he looked equally tired, at least, he thought, running his aching mind back over the journey which had brought them here.

  On the face of it, the whole thing was preposterous, and only the fact that Admiral McLain also knew Dick Aston could account for it. Even so, he'd been incredulous and a bit incensed by the paucity of the information Morris had for him. In the end, though, CINCLANT had agreed that if there was the slightest possibility Aston really was onto something the trip had to be made, and things had begun to roll.

  Their original plan to fly out on an Air Force B-1B scheduled for a training mission to Britain had been scrubbed when the South Atlantic suddenly turned hot. Morris shook his head sadly, wondering what had gone wrong. He had many contacts in the Royal Navy, and he'd been positive the Brits contemplated no offensive action. But something had hit the fan down there, and the Argentinean charges of unprovoked attacks and the massacre and mutilation of prisoners sounded ugly, indeed. It was too bad the US hadn't had a recon bird up to see what was going on for itself, but it appeared that the first the Brits knew of it had been a sudden, totally unexpected strike on one of their LPH assault ships by a quartet of the Mirage 2000-5s which had finally replaced the venerable Super Entendards as Argentina's primary launch platform for the Exocet.

  HMS Ocean had been on station off the Falklands with the better part of a full battalion of the Royal Marines on board when the surprise attack caught her at sea. Her close-in defenses had managed to stop two or three missiles, but the others had gotten through. She'd simply blown up, and, in the face of horrible casualties, the UK had responded in strength. The reports were still coming in, filtered to him through Navy channels even out here, but it sounded like the tanker-supported Tornado squadrons the RAF had deployed three months ago were beating holy hell out of the Argies' airfields. The reports indicated the Brits' decision to base a pair of E-3D AWACS aircraft on Port Stanley was paying dividends, too; they'd apparently hacked over thirty Argy attack planes and fighters out of the sky in the past twelve hours.

  But the sudden carnage had captured the Air Force's attention—especially when Argentina indignantly accused the US of complicity in the initial British attack. And if their claims were accurate, they had a point, Morris admitted unhappily, for the US diplomatic corps and intelligence agencies had assured Buenos Aires that no British offensive action was planned. At any rate, the Air Force had decided to keep the big bombers closer to home.

  The shooting in the South Atlantic made this a terrible time for CINCLANT's top intelligence types to be elsewhere, yet Admiral McLain had not wavered. He had a battle group built around the carriers Nimitz and Washington heading south just in case, but he'd sent Morris and Hastings off anyway. In default of the B-1, he'd put them aboard an S-3 Viking, and the carrier-based antisub aircraft had delivered them to the RAF airfield at Stornoway, Scotland, after a five-hour flight which would live forever in Morris's memory. The terrible weather had given him a whole new respect for the men who flew patrols aboard the four-place aircraft, and the fact that the flight crew were not allowed to ask questions about the absence of their normal tactical crew hadn't made the flight a particularly sociable experience.

  At least the weather had improved as they approached the British Isles, and the helicopter flight from Stornoway to Holy Loch wouldn't have been too bad, except for the fact that helicopters had to be the noisiest form of transport yet invented by man. Every muscle ached, and the stump of his right leg throbbed. Dick had better have a damned good reason, Morris thought with ye
t another stab of resentment and anticipation.

  "They'll be down in about ten minutes, Milla," Aston warned.

  Ludmilla looked up from the paper wreckage littering Lieutenant Shu's cramped office and shrugged. She looked completely rested, he thought with just a trace of jealousy. She was clear-eyed and her face was relaxed—in sharp contrast to his own red-rimmed eyes and tension. She'd made him shower and shave, and his body appreciated the sense of freshness, but he knew it was false energy.

  "I'm about as ready as I can be," she said calmly. She turned her head and smiled; Lieutenant Shu was bent over her desk, head pillowed on her folded arms, and a faintly audible snore came from her. Ludmilla rose quietly, took Aston's elbow, and led him back to the isolation section without disturbing the doctor. An armed Marine corporal followed them, then joined the sentry already there.

  "You're sure you can decide without the doc?" Aston asked as soon as the door closed behind them.

  "Positive," Ludmilla said confidently, then qualified her statement. "Or let's say as positive as I can be. There's an element of risk, but I think it's acceptable. It'll have to be, won't it?" Her clipped accent had sharpened, burning through the carefully cultivated softening she'd worked on so hard. It was the only sign of anxiety she showed.

  "What's the verdict to date, then?"

  "Admiral Rose is safe," Ludmilla said, "but not Captain Helsing. Nor, I'm sorry to say, is Doctor Shu. The XO is all right, and so are most of the Marine officers." She shrugged again. "Other than that, the numbers seem about what they'd've been back home. It looks like thirty-six of the hundred and ten we tested could be picked up by the Troll."

  "Um. At least Jack's okay," Aston said, rubbing his bald pate wearily. "If worse comes to worst, we can tell him even if we can't tell M&M or Commander Hastings."

  "Don't borrow trouble, Dick. We'll know soon enough, and then—"

  She broke off as someone knocked quietly on the hatch.

  Mordecai Morris was impressed by the security Aston seemed to deem appropriate. The decks were deserted, as were the passages between helipad and sickbay, but McKee's Marine detachment was in evidence—and armed. Not just with side arms, either.

  Their Marine lieutenant guide stopped outside sickbay, and the two sentries there came to attention as he knocked on the hatch.

  "Enter," a deep voice called, and the lieutenant opened the hatch and stood aside. Morris and Hastings exchanged speaking glances as they passed between the armed guards, then turned their attention to the two people awaiting them.

  They both recognized Aston, and Morris was struck by his exhaustion. He looked spruce enough, but his eyes were red and swollen and his face was weary. He was in civilian dress, but the young woman—girl, rather—sitting on the edge of the bed wore a weird combination of Navy dungarees and one of those gaudy, silk-screened tee-shirts Morris loathed and abominated.

  He was surprised to find anyone with Aston, and that prompted him to give the girl another, longer look. She returned his regard levelly, with neither uncertainty nor the arrogance some teenagers used to mask any lack of assurance, and she was a good-looking kid. Not beautiful, but striking—especially with those incredible blue eyes. A little more muscular than he liked, but, then, he was indolent by nature.

  "Mordecai," Aston said, and extended his hand. Morris felt the big, calloused hand envelop his with its customary combination of crushing strength and careful restraint and hoped he looked less worn out than Aston.

  "Dick." He squeezed back, then nodded to Hastings. "You know Jayne Hastings, I think?"

  "We've met." Aston extended his hand to the lieutenant commander in turn. She smiled, but her green eyes burned behind her glasses.

  "All right, folks," Aston continued more briskly, "before we do anything else, we need to see your EEGs."

  "Dick, what the—"

  "Bear with me, M&M," Aston said softly, and Morris was surprised by the almost entreating note in his powerful voice. That silenced him, and he opened his briefcase and dragged out several folded sheets of paper.

  "All right, Dick," he sighed. "Here. And Admiral McLain figured it might be as well to send his along, too."

  "He did? Four-oh!" Aston exclaimed. "I knew you were a persuasive bastard!" He took the EEGs and, to Morris's surprise (though why anything should surprise him at this point eluded him), handed them to the girl. "Here, Milla," he said, and Morris made his eyebrows stay put despite the odd gentleness in Dick's voice. Could he—? No! It was preposterous.

  The girl sat cross-legged on the bed and spread the charts over her lap. She looked like a Girl Scout practicing origami, Morris thought, but her smooth young face was intent. She ran a rosy fingertip across the first graph, clearly searching for something, then set it aside to check the second. Then the third. She looked up at Aston and drew a deep breath, her eyes brightening with what could only be relief, as she nodded.

  "Clean sweep," she said softly. "All three of them."

  "Thank God," Aston murmured reverently, and sank into the chair by the bed. Morris stared at him in consternation as he rubbed his bald head. It was a gesture Morris had seen often, but Aston's rock-steady fingers had never trembled before, not even after the firefight in Amman.

  "Dick?" His friend's reaction had banished his last frustration. The pressure under which this ill-assorted pair labored was too obvious.

  "Sorry, Mordecai." Aston shook his head and managed a tired smile. "You'll be pleased to know that you two—and Admiral McLain—belong to a select group. One cleared for the whole story, as it were. Sit down."

  He gestured at the extra chairs crowding the small compartment, and the intelligence officers sat wordlessly, staring first at each other and then at him.

  "People," he said slowly, "we've been invaded." He saw their shoulders stiffen and grinned tiredly. "In fact, we've been invaded twice—once by the bad guys and once by the good guys. Unfortunately, it looks like the bad guys have the force advantage, and, unless we can figure out how to turn things around, we're all in one hell of a mess."

  He had their undivided attention, and the absurdity of the situation appealed to his sense of humor. He repressed an exhaustion-spawned urge to giggle and cleared his throat, instead.

  "Commander Morris, Lieutenant Commander Hastings, allow me to introduce the good guys," he said, waving a hand at Ludmilla. "This is Colonel Ludmilla Leonovna, people—not a Russian," he added quickly, seeing the same initial assumption in both pairs of eyes and remembering his own first reaction. Amusement strengthened his voice. "Not even a Terran, really. You see, she comes from Sigma Draconis. . . ."

  " . . . so that's the story," Aston finished three hours later, and the intelligence officers shook their heads in unison. The tale he and Ludmilla had told was incredible, preposterous, impossible to believe . . . and carried the unmistakable ring of truth.

  "Dear God," Morris said softly, speaking for the first time in over half an hour. "Dear sweet God in Heaven."

  "Amen," Hastings said, equally softly, but there was worry in her eyes. She rubbed the tip of her nose gently for several seconds, then glanced sharply at Ludmilla.

  "Excuse me, Colonel—" she began.

  "Please, Ludmilla. Or Milla," Ludmilla interrupted.

  "All right, Ludmilla," Hastings agreed. "But I've got two burning questions for you."

  "Only two?" Ludmilla asked with a crooked smile.

  "Two immediate ones," Hastings acknowledged with a shadow of an answering smile. "First, and most pressingly, there's the matter of this symbiote of yours. You say it's transmitted by direct blood transfer?"

  "Yes."

  "Then I think we have a problem," Hastings said softly. "Possibly a very serious one." Ludmilla raised an eyebrow, inviting her to continue. "Mosquitoes," Hastings said softly, and felt Morris stiffen beside her.

  "Don't worry," Ludmilla said quickly. "Believe me, the Normals of my own time worried about the same thing, but we never found a single i
nstance of transmission by any insect or vermin vector."

  "Why not?" Hastings asked sharply.

  "Two reasons," Ludmilla replied imperturbably. "First, our symbiotes don't seem to approve of insect bites; they exude a sort of natural insect repellent. But the second reason is even more effective. It takes the average human a little less than twelve hours to go into crisis if she's infected with the symbiote, but it acts a lot faster on smaller life forms and none of them survive. Any bug that bites me will be dead before it gets its proboscis out of my bloodstream. It'll never live long enough to transmit it to anyone else."

  "Oh." Hastings mulled that over for a moment, then nodded slowly. "But what about insects on your home planet?" she asked curiously. "If they're immune because of their different amino acids . . . ?"

  "Commander Hastings," Ludmilla said gently, "one of Midgard's main tourist attractions is that the local insects don't like the taste of humans."

  "That would be an attraction," Hastings agreed with a smile, and Ludmilla felt her spirits rise. That smile carried acceptance as well as amusement. For a moment, she'd been afraid Hastings was going to turn paranoid on her. She'd seen too many people of her own time do exactly the same, and with far less reason.

  "But you said you had a second question?" she prompted after a minute.

  "Oh, yes! I don't pretend to be an expert, but it occurs to me that this whole thing represents a causal nightmare."

  "I couldn't agree more," Ludmilla said sincerely.

  "Well, if we accept causality at all, then it sounds to me like we're faced with the disagreement between the Copenhagen school and the Many-Worlds interpretation," Hastings said. "The whole question of what happens when the superposition collapses and—"
