Garth Nix: Infestation

They were the usual motley collection of freelance vampire hunters. Two men, wearing combinations of jungle camouflage and leather. Two women, one almost indistinguishable from the men though with a little more style in her leather armour accessories, and the other looking like she was about to assault the south face of a serious mountain. Only her mouth was visible, a small oval of flesh not covered by balaclava, mirror shades, climbing helmet and hood.

They had the usual weapons: four or five short wooden stakes in belt loops; snap-holstered handguns of various calibers, all doubtless chambered with Wood-N-Death® low-velocity timber-tipped rounds; big silver-edged bowie or other hunting knife, worn on the hip or strapped to a boot; and crystal vials of holy water hung like small grenades on pocket loops.

Protection, likewise, tick the usual boxes. Leather neck and wrist guards; leather and woven-wire reinforced chaps and shoulder pauldrons over the camo; leather gloves with metal knuckle plates; Army or climbing helmets.

And lots of crosses, oh yeah, particularly on the two men. Big silver crosses, little wooden crosses, medium-sized turned ivory crosses, hanging off of everything they could hang off.

In other words, all four of them were lumbering, bumbling mountains of stuff that meant that they would be easy meat for all but the newest and dumbest vampires.

They all looked at me as I walked up. I guess their first thought was to wonder what the hell I was doing there, in the advertised meeting place, outside a church at 4:30 pm on a winter's day while the last rays of the sun were supposedly making this consecrated ground a double no-go zone for vampires.

"You're in the wrong place, surfer boy," growled one of the men.

I was used to this reaction. I guess I don't look like a vampire hunter much anyway, and I particularly didn't look like one that afternoon. I'd been on the beach that morning, not knowing where I might head to later, so I was still wearing a yellow Quiksilver T-shirt and what might be loosely described as old and faded blue board shorts, but "ragged" might be more accurate. I hadn't had shoes on, but I'd picked up a pair of sandals on the way. Tan Birkenstocks, very comfortable. I always prefer sandals to shoes. Old habits, I guess.

I don't look my age, either. I always looked young, and nothing's changed, though "boy" was a bit rough coming from anyone under forty-five, and the guy who'd spoken was probably closer to thirty. People older than that usually leave the vampire hunting to the government, or paid professionals.

"I'm in the right place," I said, matter-of-fact, not getting into any aggression or anything. I lifted my 1968-vintage vinyl Pan-Am airline bag. "Got my stuff here. This is the meeting place for the vampire hunt?"

"Yes," said the mountain-climbing woman.

"Are you crazy?" asked the man who'd spoken to me first. "This isn't some kind of doper excursion. We're going up against a nest of vampires!"

I nodded and gave him a kind smile.

"I know. At least ten of them, I would say. I swung past and had a look around on the way here. At least, I did if you're talking about that condemned factory up on the river heights."

"What! But it's cordoned off-and the vamps'll be dug in till nightfall."

"I counted the patches of disturbed earth," I explained. "The cordon was off. I guess they don't bring it up to full power till the sun goes down. So, who are you guys?"

"Ten!" exclaimed the second man, not answering my question. "You're sure?"

"At least ten," I replied. "But only one Ancient. The others are all pretty new, judging from the spoil."

"You're making this up," said the first man. "There's maybe five, tops. They were seen together and tracked back. That's when the cordon was established this morning."

I shrugged and half-unzipped my bag.

"I'm Jenny," said the mountain-climber, belatedly answering my question. "The… the vampires got my sister, three years ago. When I heard about this infestation I claimed the Relative's Right."

"I've got a twelve-month permit," said the second man. "Plan to turn professional. Oh yeah, my name's Karl."

"I'm Susan," said the second woman. "This is our third vampire hunt. Mike's and mine, I mean."

"She's my wife," said the belligerent Mike. "We've both got twelve-month permits. You'd better be legal too, if you want to join us."

"I have a special licence," I replied. The sun had disappeared behind the church tower, and the street lights were flicking on. With the bag unzipped, I was ready for a surprise. Not that I thought one was about to happen. At least, not immediately. Unless I chose to spring one.

"You can call me J."

"Jay?" asked Susan.

"Close enough," I replied. "Does someone have a plan?"

"Yeah," said Mike. "We stick together. No hot-dogging off, or chasing down wounded vamps or anything like that. We go in as a team, and we come out as a team."

"Interesting," I said. "Is there… more to it?"

Mike paused to fix me with what he obviously thought was his steely gaze. I met it and after a few seconds he looked away. Maybe it's the combination of very pale blue eyes and dark skin, but not many people look at me directly for too long. It might just be the eyes. There've been quite a few cultures who think of very light blue eyes as the colour of death. Perhaps that lingers, resonating in the subconscious even of modern folk.

"We go through the front door," he said. "We throw flares ahead of us. The vamps should all be digging out on the old factory floor, it's the only place where the earth is accessible. So we go down the fire stairs, throw a few more flares out the door then go through and back up against the wall. We'll have a clear field of fire to take them down. They'll be groggy for a couple of hours yet, slow to move. But if one or two manage to close, we stake them."

"The young ones will be slow and dazed," I said. "But the Ancient will be active soon after sundown, even if it stays where it is-and it's not dug in on the factory floor. It's in a humungous clay pot outside an office on the fourth floor."

"We take it first, then," said Mike. "Not that I'm sure I believe you."

"It's up to you," I said. I had my own ideas about dealing with the Ancient, but they would wait. No point upsetting Mike too early. "There's one more thing."

"What?" asked Karl.

"There's a fresh-made vampire around, from last night. It will still be able to pass as human for a few more days. It won't be dug-in, and it may not even know it's infected."

"So?" asked Mike. "We kill everything in the infested area. That's all legal."

"How do you know this stuff?" asked Jenny.

"You're a professional, aren't you," said Karl. "How long you been pro?"

"I'm not exactly a professional," I said. "But I've been hunting vampires for quite a while."

"Can't have been that long," said Mike. "Or you'd know better than to go after them in just a T-shirt. What've you got in that bag? Sawn-off shotgun?"

"Just a stake and a knife," I replied. "I'm a traditionalist. Shouldn't we be going?"

The sun was fully down, and I knew the Ancient, at least, would already be reaching up through the soil, its mildewed, mottled hands gripping the rim of the earthenware pot that had once held a palm or something equally impressive outside the factory manager's office.

"Truck's over there," said Mike, pointing to a flashy new silver pick-up. "You can ride in the back, surfer boy."

"Fresh air's a wonderful thing."

As it turned out, Karl and Jenny wanted to sit in the back too. I sat on a tool box that still had shrink-wrap around it, Jenny sat on a spare tire and Karl stood looking over the cab, scanning the road, as if a vampire might suddenly jump out when we were stopped at the lights.

"Do you want a cross?" Jenny asked me after we'd gone a mile or so in silence. Unlike Mike and Karl she wasn't festooned with them, but she had a couple around her neck. She started to take a small wooden one off, lifting it by the chain.

I shook my head, and raised my T-shirt up under my arms, to show the scars. Jenny recoiled in horror and gasped, and Karl looked around, hand going for his.41 Glock. I couldn't tell whether that was jumpiness or good training. He didn't draw and shoot, which I guess meant good training.

I let the T-shirt fall, but it was up long enough for both of them to see the hackwork tracery of scars that made up a kind of "T" shape on my chest and stomach. But it wasn't a "T". It was a Tau Cross, one of the oldest Christian symbols and still the one that vampires feared the most, though none but the most ancient knew why they fled from it.

"Is that… a cross?" asked Karl.

I nodded.

"That's so hardcore," said Karl. "Why didn't you just have it tattooed?"

"It probably wouldn't work so well," I said. "And I didn't have it done. It was done to me."

I didn't mention that there was an equivalent tracery of scars on my back as well. These two Tau Crosses, front and back, never faded, though my other scars always disappeared only a few days after they healed.

"Who would-" Jenny started to ask, but she was interrupted by Mike banging on the rear window of the cab-with the butt of his pistol, reconfirming my original assessment that he was the biggest danger to all of us. Except for the Ancient Vampire. I wasn't worried about the young ones. But I didn't know which Ancient it was, and that was cause for concern. If it had been encysted since the drop it would be in the first flush of its full strength. I hoped it had been around for a long time, lying low and steadily degrading, only recently resuming its mission against humanity.

"We're there," said Karl, unnecessarily.

The cordon fence was fully established now. Sixteen feet high and lethally electrified, with old-fashioned limelights burning every ten feet along the fence, the sound of the hissing oxygen and hydrogen jets music to my ears. Vampires loathe limelight. Gaslight has a lesser effect, and electric light hardly bothers them at all. It's the intensity of the naked flame they fear.

The fire brigade was standing by because of the limelights, which though modernized were still occasionally prone to massive accidental combustion; and the local police department was there en masse to enforce the cordon. I saw the bright white bulk of the state Vampire Eradication Team's semi-trailer parked off to one side. If we volunteers failed, they would go in, though given the derelict state of the building and the reasonable space between it and the nearest residential area it was more likely they'd just get the Air Force to do a fuel-air explosion dump.

The VET personnel would be out and about already, making sure no vampires managed to get past the cordon. There would be crossbow snipers on the upper floors of the surrounding buildings, ready to shoot fire-hardened oak quarrels into vampire heads. It wasn't advertised by the ammo manufacturers, but a big old vampire could take forty or fifty Wood-N-Death® or equivalent rounds to the head and chest before going down. A good inch-diameter yard-long quarrel or stake worked so much better.

There would be a VET quick response team somewhere close as well, outfitted in the latest metal-mesh armour, carrying the automatic weapons the volunteers were not allowed to use-with good reason, given the frequency with which volunteer vampire hunters killed each other even when only armed with handguns, stakes and knives.

I waved at the window of the three-storey warehouse where I'd caught a glimpse of a crossbow sniper, earning a puzzled glance from Karl and Jenny, then jumped down. A police sergeant was already walking over to us, his long, harsh limelit shadow preceding him. Naturally, Mike intercepted him before he could choose who he wanted to talk to.

"We're the volunteer team."

"I can see that," said the sergeant. "Who's the kid?"

He pointed at me. I frowned. The kid stuff was getting monotonous. I don't look that young. Twenty at least, I would have thought.

"He says his name's Jay. He's got a 'special licence.' That's what he says."

"Let's see it then," said the sergeant, with a smile that suggested he was looking forward to arresting me and delivering a three-hour lecture. Or perhaps a beating with a piece of rubber pipe. It isn't always easy to decipher smiles.

"I'll take it from here, Sergeant," said an officer who came up from behind me, fast and smooth. He was in the new metal-mesh armour, like a wetsuit, with webbing belt and harness over it, to hold stakes, knife, WP grenades (which actually were effective against the vamps, unlike the holy water ones) and handgun. He had an H &K MP5-PDW slung over his shoulder. "You go and check the cordon."

"But Lieutenant, don't you want me to take-"

"I said check the cordon."

The sergeant retreated, smile replaced by a scowl of frustration. The VET lieutenant ignored him.

"Licences, please," he said. He didn't look at me, and unlike the others I didn't reach for the plasticated, hologrammed, data-chipped card that was the latest version of the volunteer vampire hunter licence.

They held their licences up and the reader that was somewhere in the lieutenant's helmet picked up the data and his earpiece whispered whether they were valid or not. Since he was nodding, we all knew they were valid before he spoke.

"OK, you're good to go whenever you want. Good luck."

"What about him?" asked Mike, gesturing at me with his thumb.

"Him too," said the lieutenant. He still didn't look at me. Some of the VET are funny like that. They seem to think I'm like an albatross or something. A sign of bad luck. I suppose it's because wherever the vampire infestations are really bad, then I have a tendency to show up as well. "He's already been checked in. We'll open the gate in five, if that suits you."

"Sure," said Mike. He lumbered over to face me. "There's something funny going on here, and I don't like it. So you just stick to the plan, OK?"

"Actually, your plan sucks," I said calmly. "So I've decided to change it. You four should go down to the factory floor and take out the vampires there. I'll go up against the Ancient."

"Alone?" asked Jenny. "Shouldn't we stick together like Mike says?"

"Nope," I replied. "It'll be out and unbending itself now. You'll all be too slow."

"Call this sl-" Mike started to say, as he tried to poke me forcefully in the chest with his forefinger. But I was already standing behind him. I tapped him on the shoulder, and as he swung around, ran behind him again. We kept this up for a few turns before Karl stopped him.

"See what I mean? And an Ancient Vampire is faster than me."

That was blarney. Or at least I hoped it was. I'd met Ancient Vampires who were as quick as I was, but not actually faster. Sometimes I did wonder what would happen if one day I was a fraction slower and one finally got me for good and all. Some days, I kind of hoped that it would happen.

But not this day. I hadn't had to go up against any vampires or anything else for over a month. I'd been surfing for the last two weeks, hanging out on the beach, eating well, drinking a little wine and even letting down my guard long enough to spend a couple of nights with a girl who surfed better than me and didn't mind having sex in total darkness with a guy who kept his T-shirt on and an old airline bag under the pillow.

I was still feeling good from this little holiday, though I knew it would only ever be that. A few weeks snatched out of…

"OK," panted Mike. He wasn't as stupid as I'd feared but he was a lot less fit than he looked. "You do your thing. We'll take the vampires on the factory floor."

"Good," I replied. "Presuming I survive, I'll come down and help you."

"What do… what do we do if we… if we're losing?" asked Jenny. She had her head well down, her chin almost tucked into her chest and her body-language screamed out that she was both scared and miserable. "I mean if there are more vampires, or if the Ancient one-"

"We fight or we die," said Karl. "No one is allowed back out through the cordon until after dawn."

"Oh, I didn't… I mean I read the brochure-"

"You don't have to go in," I said. "You can wait out here."

"I… I think I will," she said, without looking at the others. "I just can't… now I'm here, I just can't face it."

"Great!" muttered Mike. "One of us down already."

"She's too young," said Susan. I was surprised she'd speak up against Mike. I had her down as his personal doormat. "Don't give her a hard time, Mike."

"No time for anything," I said. "They're getting ready to power down the gate."

A cluster of regular police officers and VET agents were taking up positions around the gate in the cordon fence. We walked over, the others switching on helmet lights, drawing their handguns and probably silently uttering last-minute prayers.

The sergeant who'd wanted to give me a hard time looked at Mike, who gave him the thumbs up. A siren sounded a slow

whoop-whoop-whoop as a segment of the cordon fence powered down, the indicators along the top rail fading from a warning red to a dull green.

"Go, go, go!" shouted Mike, and he jogged forward, with Susan and Karl at his heels. I followed a few metres behind, but not too far. That sergeant had the control box for the gate and I didn't trust him not to close it on my back and power it up at the same time. I really didn't want to know what 6,600 volts at 500 milliamps would do to my unusual physiology. Or show anyone else what didn't happen, more to the point.

On the other hand, I didn't want to get ahead of Mike and co, either, because I already know what being shot in the back by accident felt like, with lead and wooden bullets, not to mention ceramic-cased tungsten-tipped penetrator rounds, and I didn't want to repeat the experience.

They rushed the front door, Mike kicking it in and bulling through. The wood was rotten and the top panel had already fallen off, so this was less of an achievement than it might have been.

Karl was quick with the flares, confirming his thorough training. Mike, on the other hand, just kept going, so the light was behind him as he opened the fire door to the left of the lobby.

Bad move. There was a vampire behind the door, and while it was no ancient, it wasn't newly hatched either. It wrapped its arms around Mike, holding on with the filaments that lined its forelegs, though to an uneducated observer it just looked like a fairly slight, tattered rag-wearing human bear-hugging him with rather longer than usual arms.

Mike screamed as the vampire started chewing on his helmet, ripping through the Kevlar layers like a buzz-saw through softwood, pausing only to spit out bits of the material. Old steel helmets are better than the modern variety, but we live in an age that values only the new.

Vamps like to get a good grip around their prey, particularly ones who carry weapons. There was nothing Mike could do, and as the vamp was already backing into the stairwell, only a second or two for someone else to do something.

The vampire fell to the ground, its forearm filaments coming loose with a sticky popping sound, though they probably hadn't penetrated Mike's heavy clothes. I pulled the splinter out of its head and put the stake of almost two-thousand-year-old timber back in the bag before the others got a proper look at the odd silver sheen that came from deep within the wood.

Karl dragged Mike back into the flare-light as Susan covered him. Both of them were pretty calm, I thought. At least they were still doing stuff, rather than freaking out.

"Oh man," said Karl. He'd sat Mike up, and then had to catch him again as he fell backwards. Out in the light, I saw that I'd waited just that second too long, perhaps from some subconscious dislike of the man. The last few vampire bites had not been just of Mike's helmet.

"What… what do we do?" asked Susan. She turned to me, pointedly not looking at her dead husband.

"I'm sorry," I said. I really meant it, particularly since it was my slackness that had let the vamp finish him off. Mike was an idiot but he didn't deserve to die, and I could have saved him. "But he's got to be dealt with the same way as the vampires now. Then you and Karl have to go down and clean out the rest. Otherwise they'll kill you too."

It usually helps to state the situation clearly. Stave off the shock with the need to do something life-saving. Adrenalin focuses the mind wonderfully.

Susan looked away for a couple of seconds. I thought she might vomit, but I'd underestimated her again. She turned back, and still holding her pistol in her right hand, reached into a thigh pocket and pulled out a Quick-Flame™.

"I should be the one to do it," she said. Karl stepped back as she thumbed the Quick-Flame™ and dropped it on the corpse. The little cube deliquesced into a jelly film that spread over the torso of what had once been a man. Then, as it splashed on the floor, it woofed alight, burning blue.

Susan watched the fire. I couldn't see much of her face, but from what I could see, I thought she'd be OK for about an hour before the shock knocked her off her feet. Provided she got on with the job as soon as possible.

"You'd better get going," I said. "If this one was already up here, the others might be out and about. Don't get ahead of your flares."

"Right," muttered Karl. He took another flare from a belt pouch. "Ready, Susan?"

"Yes."

Karl tossed the flare down the stairs. They both waited to see the glow of its light come back up, then Karl edged in, working the angle, his pistol ready. He fired almost immediately, two double taps, followed by the sound of a vamp falling back down the stairs.

"Put two more in," I called out, but Karl was already firing again.

"And stake it before you go past!" I added as they both disappeared down the stair.

As soon as they were gone, I checked the smouldering remains of Mike. Quick-Flame™ cubes are all very well, but they don't always burn everything and if there's a critical mass of organic material left then the vamp nanos can build a new one. A little, slow one, but little slow ones can grow up. I doubted there'd been enough exchange of blood to get full infestation, but it's better to be sure, so I took out the splinter again and waved it over the fragments that were left.

The sound of rapid gunshots began to echo up from below as I took off my T-shirt and tucked it in the back of my board shorts. The Tau cross on my chest was already glowing softly with a silver light, the smart matter under the scars energizing as it detected vamp activity close by. I couldn't see the one on my back, but it would be doing the same thing. Together they were supposed to generate a field that repulsed the vampires and slowed them down if they got close, but it really only worked on the original versions. The latter-day generations of vampires were such bad copies that a lot of the original tech built to deter them simply missed the mark. Fortunately, being bad copies, the newer vampires were weaker, slower, less intelligent and untrained.

I took the main stairs up to the fourth floor. The Ancient Vampire would already know I was coming so there was no point skulking up the elevator shaft or the outside drain. Like its broodmates, it had been bred to be a perfect soldier at various levels of conflict, from the nanonic frontline where it tried to replicate itself in its enemies to the gross physical contest of actually duking it out. Back in the old days it might have had some distance weapons as well, but if there was one thing we'd managed right in the original mission it was taking out the vamp weapons caches and resupply nodes.

We did a lot of things right in the original mission. We succeeded rather too well, or at least so we thought at the time. If the victory hadn't been so much faster than anticipated, the boss would never have had those years to fall in love with humans and then work out his crazy scheme to become their living god.

Not so crazy perhaps, since it kind of worked, even after I tried to do my duty and stop him. In a half-hearted way, I suppose, because he was team leader and all that. But he was going totally against regulations. I reported it and I got the order, and the rest, as they say, is history…

Using the splinter always reminds me of him, and the old days. There's probably enough smart matter in the wood, encasing his DNA and his last download to bring him back complete, if and when I ever finish this assignment and can signal for pickup. Though a court would probably confirm HQ's original order and he'd be slowed into something close to a full stop anyway.

But my mission won't be over till the last vamp is burned to ash, and this infested Earth can be truly proclaimed clean.

Which is likely to be a long, long time, and I remind myself that daydreaming about the old days is not going to help take out the Ancient Vampire ahead of me, let alone the many more in the world beyond.

I took out the splinter and the silver knife and slung my Pan-Am bag so it was comfortable, and got serious.

I heard the Ancient moving around as I stepped into what was once the outer office. The big pot was surrounded by soil and there were dirty footprints up the wall, but I didn't need to see them to know to look up. The Vamps have a desire to dominate the high ground heavily programmed into them. They always go for the ceiling, up trees, up towers, up lamp-posts.

This one was spread-eagled on the ceiling, gripping with its foreleg and trailing leg filaments as well as the hooks on what humans thought were fingers and toes. It was pretty big as Vamps go, perhaps nine feet long and weighing in at around 200 pounds. The ultra-thin waist gave away its insectoid heritage, almost as much as a real close look at its mouth would. Not that you would want a real close look at a Vamp's mouth.

It squealed when I came in and it caught the Tau emissions. The squeal was basically an ultrasonic alarm oscillating through several wavelengths. The cops outside would hear it as an unearthly scream, when in fact it was more along the lines of a distress call and emergency rally beacon. If any of its brood survived down below, they'd drop whatever they might be doing-or chewing-and rush on up.

The squeal was standard operating procedure, straight out of the manual. It followed up with more orthodox stuff, dropping straight on to me. I flipped on my back and struck with the splinter, but the Vamp managed to flip itself in mid-air and bounce off the wall, coming to a stop in the far corner.

It was fast, faster than any Vamp I'd seen for a long time. I'd scratched it with the splinter, but no more than that. There was a line of silver across the dark red chitin of its chest, where the transferred smart matter was leeching the vampire's internal electrical potential to build a bomb, but it would take at least five seconds to do that, which was way too long.

I leapt and struck again and we conducted a kind of crazy ballet across the four walls, the ceiling and the floor of the room. Anyone watching would have got motion sickness or eyeball fatigue, trying to catch blurs of movement.

At 2.350 seconds in, it got a forearm around my left elbow and gave it a good hard pull, dislocating my arm at the shoulder. I knew then it really was ancient, and had retained the programming needed to fight me. My joints have always been a weak point.

It hurt. A lot, and it kept on hurting through several microseconds as the Vamp tried to actually pull my arm off and at the same time twist itself around to start chewing on my leg.

The Tau field was discouraging the Vamp, making it dump some of its internal nanoware, so that blood started geysering out of pinholes all over its body, but this was more of a nuisance for me than any major hindrance to it.

In mid-somersault, somewhere near the ceiling, with the thing trying to wrap itself around me, I dropped the silver knife. It wasn't a real weapon, not like the splinter. I kept it for sentimental reasons, as much as anything, though silver did have a deleterious effect on younger vamps. Since it was pure sentiment, I suppose I could have left it in coin form, but then I'd probably be forever dropping some in combat and having to waste time later picking them up. Besides, when silver was still the usual currency and they were still coins I'd got drunk a few times and spent them, and it was way too big a hassle getting them back.

The Vamp took the knife-dropping as more significant than it was, which was one of the reasons I'd let it go. In the old days I would have held something serious in my left hand, like a de-weaving wand, which the vampire probably thought the knife was-and it wanted to get it and use it on me. It partially let go of my arm as it tried to catch the weapon and at that precise moment, second 2.355, I feinted with the splinter, slid it along the thing's attempted forearm block, and reversing my elbow joint, stuck it right in the forehead.

With the smart matter already at work from its previous scratch, internal explosion occurred immediately. I had shut my eyes in preparation, so I was only blown against the wall and not temporarily blinded as well.

I assessed the damage as I wearily got back up. My left arm was fully dislocated with the tendons ripped away, so I couldn't put it back. It was going to have to hang for a day or two, hurting like crazy till it self-healed. Besides that, I had severe bruising to my lower back and ribs, which would also deliver some serious pain for a day or so.

I hadn't been hurt by a Vamp as seriously for a long, long time, so I spent a few minutes searching through the scraps of mostly disintegrated vampire to find a piece big enough to meaningfully scan. Once I got it back to the jumper I'd be able to pick it apart on the atomic level to find the serial number on some of its defunct nanoware.

I put the scrap of what was probably skeleton in my flight bag, with the splinter and the silver knife, and wandered downstairs. I left it unzipped, because I hadn't heard any firing for a while, which meant either Susan and Karl had cleaned up, or the vamps had cleaned up Susan and Karl. But I put my T-shirt back on. No need to scare the locals. It was surprisingly clean, considering. My skin and hair sheds vampire blood, so the rest of me looked quite respectable as well. Apart from the arm hanging down like an orangutang's that is.

I'd calculated the odds at about 5:2 that Susan and Karl would win, so I was pleased to see them in the entrance lobby. They both jumped when I came down the stairs, and I was ready to move if they shot at me, but they managed to control themselves.

"Did you get them all?" I asked. I didn't move any closer.

"Nine," said Karl. "Like you said. Nine holes in the ground, nine burned vampires."

"You didn't get bitten?"

"Does it look like we did?" asked Susan, with a shudder. She was clearly thinking about Mike.

"Vampires can infect with a small, tidy bite," I said. "Or even about half a cup of their saliva, via a kiss."

Susan did throw up then, which is what I wanted. She wouldn't have if she'd been bitten. I was also telling the truth. While they were designed to be soldiers, the vampires were also made to be guerilla fighters, working amongst the human population, infecting as many as possible in small, subtle ways. They only went for the big chow-down in full combat.

"What about you?" asked Karl. "You OK?"

"You mean this?" I asked, threshing my arm about like a tentacle, wincing as it made the pain ten times worse. "Dislocated. But I didn't get bitten."

Neither had Karl, I was now sure. Even newly infected humans have something about them that gives their condition away, and I can always pick it.

"Which means we can go and sit by the fence and wait till morning," I said cheerily. "You've done well."

Karl nodded wearily and got his hand under Susan's elbow, lifting her up. She wiped her mouth and the two of them walked slowly to the door.

I let them go first, which was kind of mean, because the VET have been known to harbour trigger-happy snipers. But there was no sudden death from above, so we walked over to the fence and then the two of them flopped down on the ground and Karl began to laugh hysterically.

I left them to it and wandered over to the gate.

"You can let me out now," I called to the sergeant. "My work here is almost done."

"No one comes out till after dawn," replied the guardian of the city.

"Except me," I agreed. "Check with Lieutenant Harman."

Which goes to show that I can read ID labels, even little ones on metal-mesh skinsuits.

The sergeant didn't need to check. Lieutenant Harman was already looming up behind him. They had a short but spirited conversation, the sergeant told Karl and Susan to stay where they were, which was still lying on the ground essentially in severe shock, and they powered down the gate for about thirty seconds and I came out.

Two medics came over to help me. Fortunately they were VET, not locals, so we didn't waste time arguing about me going to hospital, getting lots of drugs injected, having scans, etc. They fixed me up with a collar and cuff sling so my arm wasn't dragging about the place, I said thank you and they retired to their unmarked ambulance.

Then I wandered over to where Jenny was sitting on the far side of the silver truck, her back against the rear wheel. She'd taken off her helmet and balaclava, letting her bobbed brown hair spring back out into shape. She looked about eighteen, maybe even younger, maybe a little older. A pretty young woman, her face made no worse by evidence of tears, though she was very pale.

She jumped as I tapped a little rhythm on the side of the truck.

"Oh… I thought… aren't you meant to stay inside the… the cordon?"

I hunkered down next to her.

"Yeah, most of the time they enforce that, but it depends," I said. "How are you doing?"

"Me? I'm… I'm OK. So you got them?"

"We did," I confirmed. I didn't mention Mike. She didn't need to know that, not now.

"Good," she said. "I'm sorry… I thought I would be braver. Only when the time came…"

"I understand," I said.

"I don't see how you can," she said. "I mean, you went in, and you said you fight vampires all the time. You must be incredibly brave."

"No," I replied. "Bravery is about overcoming fear, not about not having it. There's plenty I'm afraid of. Just not vampires."

"We fear the unknown," she said. "You must know a lot about vampires."

I nodded and moved my flight bag around to get more comfortable. It was still unzipped, but the sides were pushed together at the top.

"How to fight them, I mean," she added. "Since no one really knows anything else. That's the worst thing. When my sister was in… infected and then later, when she was… was killed, I really wanted to know, and there was no one to tell me anything"

"What did you want to know?" I asked. I've always been prone to show-off to pretty girls. If it isn't surfing, it's secret knowledge. Though sharing the secret knowledge only occurred in special cases, when I knew it would go no further.

"Everything we don't know," sighed Jenny. "What are they, really? Why have they suddenly appeared all over the place in the last ten years, when we all thought they were just… just made-up."

"They're killing machines," I explained. "Bioengineered self-replicating guerilla soldiers, dropped here kind of by mistake a long time ago. They've been in hiding mostly, waiting for a signal or other stimuli to activate. Certain frequencies of radiowaves will do it, and the growth of cellphone use…"

"So what, vampires get irritated by cellphones?"

A smile started to curl up one side of her mouth. I smiled too, and kept talking.

"You see, way back when, there were these good aliens and these bad aliens, and there was a gigantic space battle-"

Jenny started laughing.

"Do you want me to do a personality test before I can hear the rest of the story?"

"I think you'd pass," I said. I had tried to make her laugh, even though it was kind of true about the aliens and the space battle. Only there were just bad aliens and even worse aliens, and the vampires had been dropped on Earth by mistake. They had been meant for a world where the nights were very long.

Jenny kept laughing and looked down, just for an instant. I moved at my highest speed-and she died laughing, the splinter working instantly on both human nervous system and the twenty-four-hours-old infestation of vampire nanoware.

We had lost the war, which was why I was there, cleaning up one of our mistakes. Why I would be on Earth for countless years to come.

I felt glad to have my straightforward purpose, my assigned task. It is too easy to become involved with humans, to want more for them, to interfere with their lives. I didn't want to make the boss's mistake. I'm not human and I don't want to become human or make them better people. I was just going to follow orders, keep cleaning out the infestation, and that was that.

The bite was low on Jenny's neck, almost at the shoulder. I showed it to the VET people and asked them to do the rest.

I didn't stay to watch. My arm hurt, and I could hear a girl laughing, somewhere deep within my head.
