David Weber - The Apocalypse Troll

"How?"

"Hm?" She shook herself. "Oh. The techies built in a jammer to block Kanga scanners and programmed the escape computer for a delayed blow-out. You said he followed me down for a while?" He nodded, and she shrugged again. "He was probably scanning the wreckage to make sure we were all dead-and that's exactly what his systems told him. Then Sputnik waited till the last minute to zerch herself and blow the cockpit. The computers must have spotted you and homed on your boat." She smiled tightly. "If we'd been in deep space, the program would've aborted and I'd be dead. There's no point evading in an environment where long-term survival is impossible, and Fleet doesn't want to flash the capability when it won't do any good."

"So he's certain you're dead," Aston mused. "But how would it affect his plans if he found out you aren't?"

"I don't know," she said, frustration sharpening her tone. "Look, the Kangas came back to wipe us before we could become a threat, and he damned well knows it. But he's in a position no Troll's ever been in; there aren't any Kangas to order him around, and he 'knows' he personally killed the last humans from his own time, which means no one in 2007 can have the least scan of who he is or what he wants. For the first time in history, a Troll may be free to make his own decisions." She paused for a long moment, her eyes unfocused as she thought.

"Who can say what that means?" she continued finally. "The Kangas' programming may carry over on him, or he may be entirely on his own. What I suspect is that he's in a position to make plans of his own and that he's still considering his options. What I know is that if he finds out he didn't kill me after all, he'll feel threatened. In which case-"

"In which case," Aston interrupted thoughtfully, "he may do something we'll all regret."

"Exactly." She shivered slightly. "You have no concept of what his hate is like, Mister Aston, and of everyone in the galaxy, he hates me most. Add that I'm the one person on this planet who really knows anything about him ..." She gave a tiny toss of her head. "He'll come after me," she said softly, "and he won't care how many other people he kills to get me."

Aston felt his shoulders tighten and forced them to relax. The bright sunlight felt icy, and he suddenly realized his inner chill was personal as well as intellectual. It was important to him that this young woman survive, and not simply because of the information source she represented.

"All right," he said, forcing himself to sound cheerful, "we just have to make sure none of our 'noises'-" he grinned as he used her term "-find out about you."

"It goes a bit further than that, Mister Aston. You see-"

"Please," he interrupted again. "We've introduced ourselves, and my name's Richard-Dick, to my friends. I wish you'd use it."

"All right, Dick." She smiled, and something inside him gave a little shiver he hadn't felt in years. "But only if you stop calling me 'Colonel.' My name is Ludmilla-or, as you'd say, Milla, to my friends."

"Thank you, Milla," he said, careful to keep his smile friendly, without a trace of the attraction he felt. Damn it, she was a third his age-too damned young for the thoughts he was thinking. He tried to tell himself it was being alone with her, but he knew better. Her features were too severe ever to be beautiful, but they had something far more important. They had strength and character, and her eyes were beautiful ... and wise. Too wise for her years... .

He shook himself and hoped she'd noticed nothing. Or did he?

"You were saying something about going further?" he prompted.

"Um?" She blinked. "Oh, yes. It's not quite as simple as just clamping on security ... Dick." She gave that same little toss of her head. "You see, the Kangas did quite a bit of tinkering with the Trolls. We're not quite certain, but a lot of evidence suggests the Kangas themselves are at least rudimentary telepaths. At any rate, they tried to build that ability into the Trolls."

"It's telepathic?" Despite everything else she'd said, that thought shocked him.

"I'm afraid so. Apparently they meant to give them a com channel we couldn't jam, but it didn't work out too well. Troll brains are still basically human, and about a third of all normal humans can tap into their mental net if they know it's there. None of us can transmit, as it were, but we can 'hear' them doing it, if we know they're out there to listen to. I understand it's not a very ... pleasant thing to do, but it means they can't use their 'secure com' without being overheard, so it never gave them the advantages the Kangas apparently hoped for."

"Wait a minute." Sick suspicion tightened his throat. "If we can 'hear' them, can they-?"

"They can," she replied grimly. "Worse, they can influence human thoughts and attitudes. We found that out the hard way. If you don't know to watch for it, they can really warp you out. The number of people who can realize what's happening on their own is low, too. Very low." Her face grew even grimmer.

"We're lucky in at least two respects, though. First, a single Troll doesn't have much range-no more than a few hundred kilometers. They have a greater reach when several combine, but their touch gets a lot more evident when they do. And, secondly, I'm not one of the people who can tap them, so our Troll shouldn't be able to tap me, which means he can't pick me up to know I'm still alive. I just hope he can't read you, either."

"You and me both, lady," he said uneasily. "But how in hell are we supposed to know?"

"I've been thinking about that," she answered slowly. "There's a standard test, back home. I know you don't have the technology we do, but your people can do brain scans, can't they?"

"That depends on what you mean by 'brain scan,' " he said carefully.

"Damn," she muttered. "This language problem is terrible. I'm never certain I'm saying what I think I am!"

"Don't worry," he told her dryly. "We'll be in the same boat-if you'll pardon the pun-when we hit England."

"What?"

"Never mind. Just tell me what this brain scan is supposed to scan."

"Brain waves," she said. "Oh, back home it's all one procedure that also analyzes cellular structure and all the rest, but it's the brain waves that matter."

"That sounds like an EEG," he said. She raised her eyebrows. "An electroencephalogram," he explained. "It measures electrical charges in the brain."

"Good!" Her face brightened and she nodded vigorously. "There's a distinctive spike in the alpha waves for people who can't hear the Trolls-and the reverse, we think."

"Do you mean to tell me," he demanded, "that we have to run an EEG on anyone we consider telling about you?"

"Of course." She seemed surprised. "What's the problem?"

" 'What's the problem?' How the hell are we supposed to convince someone to have an EEG run without even telling him why?"

"Wait a tick." She cocked her head. "Back home it takes about two minutes and it's part of any medicheck. I gather that's not the case here?"

"No," he said with commendable restraint, "it's not." He went on to explain the procedure, and it was her turn to look astonished.

"Good Lord! I've never heard of anything so primitive!"

"We're a pretty primitive bunch, Milla," he said plaintively, "but you're not going to make a lot of friends if you keep reminding us of it."

"Oops." She put a hand on his forearm and squeezed gently. "I'm afraid I've got a bigger mouth than I thought."

"Don't worry," he reassured her, patting her hand in what he fondly thought was an avuncular fashion. "We are primitive by your standards, I guess, but if you're right about how important it is to blend in, you're going to have to work on attitudes as much as speech patterns."

"I know." She smiled at him, and the warmth of her expression reached deep inside him. "Anyway, if we can figure out how to arrange it, all we have to do is run one of these-EEGs?-" she used the unfamiliar term hesitantly, and he nodded "-on me and use it as a comparison base." She frowned. "I think it should be fairly simple. I know what my scan pattern looks like, and I know which spike to watch for. I only hope this EEG is similar enough to let me orient myself."
