Page 6 of The Trigger


  'Sounds like fun. Parameters?'

  Take everything we've learned so far and run with it. We now know we don't need the whole spectrum, zero to infinity. Simplify. Try to give me something smaller, more efficient, sturdier, and more self-contained - in a word, something portable.'

  'Portable?' Thayer asked, raising an eyebrow.

  'We can't test the emitter's range at the lab - the campus isn't big enough. Someone else would get hurt, in that big subdivision on the south side of Shanahan Road, or even just driving by. We need to be able to take a test rig to a Big Empty somewhere, out West, or in the middle of Lake Erie. You can build Baby Two right into the back of a panel truck if you like.'

  'Just out of curiosity, Doc - will the Trigger make gasoline explode?'

  'Good question. I don't suppose you'd take a guess for an answer.'

  'Sure - if it's your truck.' Greene said, grinning.

  'We should test gasoline next week, then. I'll tell McGhan.'

  'Probably should test kerosene and diesel fuel at the same time,' Thayer interjected. 'Unless you don't mind surprises - since there's plenty of both around.'

  Horton nodded. 'Yes. And we had all three on campus the day of the anomaly, and none of them were affected at that power level. Maybe higher output levels will affect some of the materials we now think are stable in a Trigger field. If I was making any headway on the theory, I could possibly answer that. For now, all we can do is keep testing. The other advantage of having a second unit is that we could speed up the test program.'

  'Every time we start Baby up, we're testing more than the sample in the chamber,' said Thayer. 'We already know it doesn't affect plexiglas, concrete, grapefruit, black lace and Spandex, carbonated drinks, the batteries in Gordie's cheap watch -'

  'Black lace and Spandex?' Greene repeated, looking back over his shoulder.

  I'll explain when you're older.'

  For the rest of the drive, the trio brainstormed a list of materials known to have been exposed to the Trigger field, simply by virtue of having been part of the structure, setting, or contents of Davisson Lab. But as they pulled into the driveway of the Old Market House Inn, Horton confiscated the list.

  'That's it for shop talk,' he said. 'Not another word about work. If we can't think of civilized conversation, we'll eat in silence, by god -I mean to enjoy this meal. After all, it's not every day that I put on a tie.'

  'Or eat something that wasn't served in colored paper and styrofoam,' said Greene, reaching for the door latch. 'I accept your terms. Come on - I'm starving.'

  With surprising ease, they talked only of pop-culture guilty pleasures, the demise of women's professional football, and dream vacations, while consuming tender meats, exotic vegetables, and most of two bottles of wine in the course of a two-hour meal. The only breach of Horton's edict was committed by Horton himself, in a toast.

  To the world's largest single-shot hand-load country-windage hide-your-children firearm, and the team what built it,' he said quietly. 'May we figure out what it's good for, and how to aim it.'

  'You're a sloppy drunk, Boss,' said Thayer, clinking glasses. 'But, what you said, all the same.'

  Whether it was the hour, the tranquilizing effect of the food and wine, or the sobering after-effect of the toast, there was little conversation on the way back to Columbus. Horton directed the car into the high-speed autodrive lane and let it bore westward through the moonless night while he looked out onto the darkened farms. Greene dozed, sometimes snoring lightly. Thayer watched the traffic in the self-drive lanes. A dark four-door sedan, breaking all speed limits, overtook them and melted away into the night ahead.

  'Unmarked car?' Horton suggested. 'Desperate need to find the next rest area?'

  'Secret government agency transporting captured alien to Wright-Patterson Air Force Base,' she said lightly.

  'Ah.'

  The silence seemed to be lengthening the miles, so Horton turned on the satellite radio and the last half of Count Basic's 'Kansas City Suite' saw them to the gatehouse of Greene's singles community - he had decided to taxi in the next morning rather than spend most of another hour on the road - and Stan Kenton delivered them to the Terabyte lot where Thayer's car waited.

  'It was a nice place, a good meal, Boss - thank you.' Though it sounded like an exit line, she made no move to open her door.

  'My pleasure. See you in the morning.'

  'Can I confess something?'

  Puzzled, Horton turned sideways in his seat, so he could see her face. 'Sure.'

  'I didn't enjoy tonight very much -'

  'I'm sorry -'

  'Not your fault,' she said. 'Boss, I was nervous all the way there and back, in a way I never am when we each go our own way at the end of the night, I kept thinking, one car crash, and the status quo is safe -'

  'I think Dr Brohier has enough now that he could carry on even if something happened to us.'

  'I guess probably he does - but would outsiders realize that?'

  'What are you getting at, Lee?'

  'All evening, I've been thinking about how this work threatens the power base of a lot of people who aren't going to love us for what we're doing, and who'd surely like to stop it if they had the chance. I kept wanting both you and Gordie to lower your voices in the restaurant, even though you had the No Shop Talk sign lit. I just didn't want anyone to take notice of us. I just wanted to be invisible.'

  She sighed. 'And now that I have these thoughts in my head, every sound I hear outside my condo - every time my cat gets curious about something in the middle of the night - every time I turn the key to start my car - I'm going to be nervous. Jeff, we're not going to be safe until we're no longer the only people in the world who know how to do this.'

  'I don't know that -'

  'You know that there're people out there who'll kill out of calculation - to further their interests, or protect them. They aren't just a Hollywood invention.'

  'I suppose. I confess I haven't really thought much about it.'

  'I have,' she said, her voice tight with emotion. 'My sister in Cleveland's been having trouble with gangs, because her son doesn't want to join. Their house has been shot-up three times now.' She sighed again. 'And when I was twelve, my Uncle Ted was jury foreman in a bank robbery case against the head of one of those white nationalist syndicates. The jury voted to convict.

  A week later Uncle Ted was found dead, shot sixteen times, with "Traitor" painted across the windshield of his car.'

  'I remember that,' Horton said in surprise. 'I remember seeing that on the news. I had no idea -'

  'I promised myself -' She shook her head and started over. 'I told myself I'd never let myself get caught between someone like that and what they wanted - that I'd just hunker down in the tall grass and let the lions fight it out overhead.'

  'Lee, what can I do?'

  'I think I'd like to start living at the lab,' she said. 'Ernie, too, if that's okay.'

  'Ernie's the cat?'

  Lee nodded. 'Just until we've published, and there's not so much at stake. I could use Barton's old office - it's close to the women's lounge, and the couch is long enough for me.'

  'We'll get you a bed, and a wardrobe,' he said firmly. 'And an old armchair for Ernie to claw.'

  A relieved smile brightened Lee's face. Thank you.'

  'Shall I take you around to the gate? Do you want to start tonight?'

  'No - Ernie goes crazy when I don't come home.' She thought a moment. 'But I'll bring him and a suitcase with me tomorrow, if that's all right.'

  'Of course. I'm pretty sure Site Services can rustle up a bed by quitting time, if I light a fire under them.'

  Nodding, she opened her door. 'Thanks for not making me feel like some paranoid 'fraidy-cat.'

  There's plenty out there that's worth being afraid of,' Horton said. 'Most of us cope by pretending it's not there. You had that illusion taken away from you too damn early.' He grunted. 'And I think I just lost mine. Maybe I'll ask Site Se
rvices for two beds.'

  'I'm sorry, Boss -'

  'No. Don't be. Dr Brohier tried to tell us. He couldn't have been any plainer about it. And I looked right past it, with hardly a thought for anything but the puzzle, the science.' He shook his head. 'It's late. Time to go home.'

  She started to climb out, then stopped and looked back at Horton with a penetrating earnestness. 'Jeff?'

  'What?'

  'We are going to publish, aren't we? Tell me we're not really working for Dow Chemical, or the Department of Defense. Tell me that Dr Brohier understands we can't just sell the Trigger to the high bidder - that there'll be a chance to use this work to declaw some of the lions. That's the only reason I didn't run away the first week.' She smiled ruefully. 'I wanted to, but Uncle Ted wouldn't let me.'

  'We're going to publish,' Horton said firmly. 'And the lions are going to get the surprise of their lives.'

  5: Chemistry

  Lyons, France - Smoke bombs and firecrackers chased supporters of beleaguered French president Charles Fontenay from a poorly-attended election rally on Tuesday. One woman was seriously injured in a fall from an escalator. This was the ninth time in two weeks that a Social Democrat campaign event has been disrupted by the self-styled political terrorist group Mad Dogs. Police officials announced they would meet today with representatives of the three major candidates to discuss event security and 'explore troubling rumors'.

  'Mad Dog' Manifesto Fontenay Gaining in Polls

  When the testing moved to other materials, the first subtle clues about the nature of the trigger effect began to emerge.

  A test sample of loose nitrocellulose gunpowder flared up in a single bright gout of flame. As McGhan showed them by match-burning a reference sample on the worktable, that flare represented much faster burning than would ordinarily be expected.

  'It's as if there's no convection delay - as if every grain in the pile hits the flash threshold at essentially the same instant,' said Horton. 'Like the difference between heating water in a pot on a stove and heating water in a microwave.'

  'That would help explain why Eric was so badly injured,' said Greene. 'And why my car went up like a bomb. Baby is very efficient at what he does.'

  'I wish you'd stop calling it "Baby",' Thayer griped. 'There's nothing cute and cuddly about it anymore - if there ever was.'

  'How about "Problem Child"? Is that any better?'

  'Shouldn't you be down the hall, working on Son of Problem Child?'

  'I only come down here when you're pulling the Trigger,' he said defensively, retreating toward the door. 'Ten minutes every three hours. I get lonely down there, all by myself. Look, I know you have a couple of hours of cleanup ahead of you - I'll leave you to it.'

  The next sample was black powder - the world's first explosive, and the mainstay of armies from China to England for more than three hundred years. To everyone's surprise, the test sample merely smoked and turned gray-brown. A second test at the next power level yielded the same result, with what was left rendered inert to a match.

  'It should burn,' said Horton, shaking his head. 'Black powder will catch on a spark. This is like trying to light a soggy cat.'

  'We're going to have to get our samples to an analytical chemist soon,' Thayer said. 'Something queer is happening at the compound level.'

  'We should get an analytical chemist set up in the next lab,' said Greene grumpily. 'Isn't there anyone on campus we can hit over the head and drag over here?'

  'It's at the top of my list for when Dr Brohier returns,' said Horton. 'But I don't need a chemist to tell me that the only thing gunpowder and guncotton have in common are the nitrates. And I think we're seeing that the difference between cellulose hexanitrate and potassium nitrate is the difference between flash and fizzle.'

  'I think we're going to need a physical chemist, too,' Thayer said with a frown. 'Something queer has to be happening to the electron bonds.'

  'I think we're going to need a sample of Blasting Powder B,' said Horton. When the others looked at him questioningly, he added, 'Same basic chemistry as black powder, except it contains sodium nitrate. And that will give us another big piece of the puzzle.'

  That afternoon, Horton and Thayer watched five grams of Blasting Powder B fill the test chamber with fragrant gray smoke. Neither the sample nor the residue ever showed a flame.

  'Interesting,' said Horton.

  'Indeed, Mr Spock,' said Thayer, studying her displays. 'But I want to tear that miserable excuse for a test chamber apart and rebuild it the right way. It's absurd that I can't get a spectrograph on that smoke -'

  'Lee, would you look up Mr King's report on the anomaly?'

  'Sure - what do you need?'

  'See if it has a list of the fireworks Gordie said were in his car.'

  'It's there - I remember seeing it.' Her screen flashed rapidly. Two dozen bottle rockets. One box M-60 firecrackers. One "Devastation Celebration" skyrocket assortment.'

  'That's all?'

  'That's all.' Then her eyes lit up with understanding. 'Oh! We have a little problem, don't we?'

  Horton nodded reluctant acknowledgement. 'If the black powder didn't burn, and the blasting powder didn't burn, why did the fireworks in Gordie's car go off?' He pushed his chair away from his monitoring station. I need to stretch my legs. Be back in a few.'

  The mobile emitter unit was already taking shape atop a pair of the Maintenance Section's rubber-wheeled aluminum dollies. Horton saw that the geometry of the power and control module was already well defined, and that Greene was anchoring the support section of the emitter cylinder in its upright position.

  'I've never seen anyone get to bending metal faster than you do,' Horton said. 'The vertical orientation's not going to create any problems?'

  'Not for me,' Greene said, sitting up and brushing the perspiration off his forehead. 'Half an hour pushing lines around with the cursor, and the CAM shop started turning out parts.'

  'It's what goes on in your head before you touch the cursor that's mysterious to me,' Horton said, settling on a stool near Greene's work area. 'We have a problem, Gordie.'

  Pursing his lips, Greene said nothing.

  'Come on, Gordie - don't make me be the bad guy,' said Horton. 'You must have realized we'd pick it up.'

  Greene wiped his hands on his overalls with great deliberation, then looked up and smiled a wry, rueful smile. 'Actually, I didn't. Until this morning I thought gunpowder was gunpowder. Who knew?'

  'What was in the car?'

  'An unlicensed pistol.' He snorted. 'My anti-carjacking security system. A little plastic-frame Ruger 9mm.'

  'Another Tennessee souvenir?'

  'Kentucky, actually,' said Greene. 'They still find a way to overlook any Federal law they don't like. And I guess they didn't like the 30th Amendment.' He leaned forward, resting his elbows on his thighs and slowly wringing his hands. 'Dr Horton - I'm sorry. I didn't know the fire was going to be kept in the family. I was afraid of that mandatory five-year term. And once I'd already committed myself to one version of reality - Doc, I was just too embarrassed to admit I'd lied.'

  Horton stood. 'I guess I can weather this little surprise,' he said. 'But please don't hand me any big ones. Did you replace your security system along with your car?'

  Shaking his head, Greene said, 'No. Thought about it. Decided I'd have to wait until things were clearer up here before I could assess the risks.'

  'I think it's pretty clear that the lab's not going to buy you two replacement cars,' said Horton, letting his face relax into a lazy grin. 'So if you don't feel safe out there without a pistol in the console, you can always opt for Lee's solution - or mine.'

  'What's yours?' Greene asked, cocking his head.

  Horton laughed. 'Drive a car so pocket-protector dull that no one would ever think to steal it.'

  A day's testing on black-powder fireworks confirmed that while Greene's cache migh
t have helped accelerate the car fire, it could not have started it.

  Then Horton's team turned their attention away from low-yield combustion explosives to high-yield detonating explosives. Pete McGhan sat them all down for a primer before delivering the first samples to them.

  Thirty-thirty rifle cartridge,' he said, placing a gleaming brass cylinder on the table between them. Three ccs of guncotton pro-pellant. Powder burns in a few thousandths of a second and develops a maximum detonation pressure of a few hundred pounds per square inch.'

  He placed a small putty-colored cylinder beside it. Three ccs of RDX, a.k.a. cyclonite. Detonation takes a few millionths of a second and develops a detonation pressure of millions of pounds per square inch. If your rifle can fire a 30-30 bullet two hundred meters, an RDX cartridge of the same size could damn near reach orbit - if there was a gun anywhere that wouldn't shatter to splinters first.

  There are more kinds of high explosive than any of you probably realize - more than a hundred readily available formulations, probably another hundred that have been used in the past and abandoned, plus a couple of dozen more that are military or industrial secrets. But most of them are built around one or more of half a dozen or so basic compounds - ammonium nitrate, picric acid, nitroglycerin, PETN, RDX, TNT. Dr Brohier's instructions were for me to provide appropriate samples from each family in the purest and simplest formulation available, then let the results guide the choice of which blends to investigate.

  'Almost everything I've told you about what you've tested so far doesn't apply to what's coming up. Dynamite can burn without exploding. But the nitroglycerin in the dynamite will explode on a shock no greater than this,' he said, snapping a pencil sharply against the edge of the table. Everyone jumped. 'While Nitromex is so stable you can shoot a pistol at it or set off a detonating cord under it.

  'In fact, the detonating explosives are so different from the combustion explosives, and one family from another, that I have a private bet with myself - I don't think your device is going to touch them. Any of them.
