We ate sand for dinner. Outside the security bunker, the mining robots rumbled back and forth, ripping deeper into the earth, turning it into a mush of tailings and rock acid that they left in exposed ponds when they hit the water table, or piled into thousand-foot mountainscapes of waste soil. It was comforting to hear those machines cruising back and forth all day. Just you and the bots and the profits, and if nothing got bombed while you were on duty, there was always a nice bonus.

  After dinner we sat around and sharpened Lisa's skin, implanting blades along her limbs so that she was like a razor from all directions. She'd considered monomol blades, but it was too easy to take a limb off accidentally, and we lost enough body parts as it was without adding to the mayhem. That kind of garbage was for people who didn't have to work: aesthetes from New York City and California.

  Lisa had a DermDecora kit for the sharpening. She'd bought it last time we'd gone on vacation and spent extra to get it, instead of getting one of the cheap knock-offs that were cropping up. We worked on cutting her skin down to the bone and setting the blades. A friend of ours in L.A said that he just held DermDecora parties so everyone could do their modifications and help out with the hard-to-reach places.

  Lisa had done my glowspine, a sweet tracery of lime landing lights that ran from my tailbone to the base of my skull, so I didn't mind helping her out, but Jaak, who did all of his modification with an old-time scar and tattoo shop in Hawaii, wasn't so pleased. It was a little frustrating because her flesh kept trying to close before we had the blades set, but eventually we got the hang of it, and an hour later, she started looking good.

  Once we finished with Lisa's front settings, we sat around and fed her. I had a bowl of tailings mud that I drizzled into her mouth to speed her integration process. When we weren't feeding her, we watched the dog. Jaak had shoved it into a makeshift cage in one corner of our common room. It lay there like it was dead.

  Lisa said, "I ran its DNA. It really is a dog."

  "Bunbaum believe you?"

  She gave me a dirty look. "What do you think?"

  I laughed. At SesCo, tactical defense responders were expected to be fast, flexible, and deadly, but the reality was our SOP was always the same: drop nukes on intruders, slag the leftovers to melt so they couldn't regrow, hit the beaches for vacation. We were independent and trusted as far as tactical decisions went, but there was no way SesCo was going to believe its slag soldiers had found a dog in their tailings mountains.

  Lisa nodded. "He wanted to know how the hell a dog could live out here. Then he wanted to know why we didn't catch it sooner. Wanted to know what he pays us for." She pushed her short blond hair off her face and eyed the animal. "I should have slagged it."

  "What's he want us to do?"

  "It's not in the manual. He's calling back."

  I studied the limp animal. "I want to know how it was surviving. Dogs are meat eaters, right?"

  "Maybe some of the engineers were giving it meat. Like Jaak did."

  Jaak shook his head. "I don't think so. The sucker threw up my arm almost right after he ate it." He wiggled his new stump where it was rapidly regrowing. "I don't think we're compatible for it."

  I asked, "But we could eat it, right?"

  Lisa laughed and took a spoonful of tailings. "We can eat anything. We're the top of the food chain."

  "Weird how it can't eat us."

  "You've probably got more mercury and lead running through your blood than any pre-weeviltech animal ever could have had."

  "That's bad?"

  "Used to be poison."

  "Weird."

  Jaak said, "I think I might have broken it when I put it in the cage." He studied it seriously. "It's not moving like it was before. And I heard something snap when I stuffed it in."

  "So?"

  Jaak shrugged. "I don't think it's healing."

  The dog did look kind of beat up. It just lay there, its sides going up and down like a bellows. Its eyes were half-open, but didn't seem to be focused on any of us. When Jaak made a sudden movement, it twitched for a second, but it didn't get up. It didn't even growl.

  Jaak said, "I never thought an animal could be so fragile."

  "You're fragile, too. That's not such a big surprise."

  "Yeah, but I only broke a couple bones on it, and now look at it. It just lies there and pants."

  Lisa frowned thoughtfully. "It doesn't heal." She climbed awkwardly to her feet and went to peer into the cage. Her voice was excited. "It really is a dog. Just like we used to be. It could take weeks for it to heal. One broken bone, and it's done for."

  She reached a razored hand into the cage and sliced a thin wound into its shank. Blood oozed out, and kept oozing. It took minutes for it to begin clotting. The dog lay still and panted, clearly wasted.

  She laughed. "It's hard to believe we ever lived long enough to evolve out of that. If you chop off its legs, they won't regrow." She cocked her head, fascinated. "It's as delicate as rock. You break it, and it never comes back together." She reached out to stroke the matted fur of the animal. "It's as easy to kill as the hunter."

  The comm buzzed. Jaak went to answer.

  Lisa and I stared at the dog, our own little window into pre-history.

  Jaak came back into the room. "Bunbaum's flying out a biologist to take a look at it."

  "You mean a bio-engineer," I corrected him.

  "Nope. Biologist. Bunbaum said they study animals."

  Lisa sat down. I checked her blades to see if she'd knocked anything loose. "There's a dead-end job."

  "I guess they grow them out of DNA. Study what they do. Behavior, shit like that."

  "Who hires them?"

  Jaak shrugged. "Pau Foundation has three of them on staff. Origin of life guys. That's who's sending out this one. Mushi-something. Didn't get his name."

  "Origin of life?"

  "Sure, you know, what makes us tick. What makes us alive. Stuff like that."

  I poured a handful of tailings mud into Lisa's mouth. She gobbled it gratefully. "Mud makes us tick," I said.

  Jaak nodded at the dog. "It doesn't make that dog tick."

  We all looked at the dog. "It's hard to tell what makes it tick."

  Lin Musharraf was a short guy with black hair and a hooked nose that dominated his face. He had carved his skin with swirling patterns of glow implants, so he stood out as cobalt spirals in the darkness as he jumped down from his chartered HEV.

  The centaurs went wild about the unauthorized visitor and corralled him right up against his ship. They were all over him and his DNA kit, sniffing him, running their scanners over his case, pointing their 101s into his glowing face and snarling at him.

  I let him sweat for a minute before calling them away. The centaurs backed off, swearing and circling, but didn't slag him. Musharraf looked shaken. I couldn't blame him. They're scary monsters: bigger and faster than a man. Their behavior patches make them vicious, their sentience upgrades give them the intelligence to operate military equipment, and their basic fight/flight response is so impaired that they only know how to attack when they're threatened. I've seen a half-slagged centaur tear a man to pieces barehanded and then join an assault on enemy ridge fortifications, dragging its whole melted carcass forward with just its arms. They're great critters to have at your back when the slag starts flying.

  I guided Musharraf out of the scrum. He had a whole pack of memory addendums blinking off the back of his skull: a fat pipe of data retrieval, channeled direct to the brain, and no smash protection. The centaurs could have shut him down with one hard tap to the back of the head. His cortex might have grown back, but he wouldn't have been the same. Looking at those blinking triple fins of intelligence draping down the back of his head, you could tell he was a typical lab rat. All brains, no survival instincts. I wouldn't have stuck mem-adds into my head even for a triple bonus.

  "You've got a dog?" Musharraf asked when we were out of reach of the centaurs.

  "We think so
." I led him down into the bunker, past our weapons racks and weight rooms to the common room where we'd stored the dog. The dog looked up at us as we came in, the most movement it had made since Jaak put it in the cage.

  Musharraf stopped short and stared. "Remarkable."

  He knelt in front of the animal's cage and unlocked the door. He held out a handful of pellets. The dog dragged itself upright. Musharraf backed away, giving it room, and the dog followed stiff and wary, snuffling after the pellets. It buried its muzzle in his brown hand, snorting and gobbling at the pellets.

  Musharraf looked up. "And you found it in your tailings pits?"

  "That's right."

  "Remarkable."

  The dog finished the pellets and snuffled his palm for more. Musharraf laughed and stood. "No more for you. Not right now." He opened his DNA kit, pulled out a sampler needle and stuck the dog. The sampler's chamber filled with blood.

  Lisa watched. "You talk to it?"

  Musharraf shrugged. "It's a habit."

  "But it's not sentient."

  "Well, no, but it likes to hear voices." The chamber finished filling. He withdrew the needle, disconnected the collection chamber and fitted it into the kit. The analysis software blinked alive and the blood disappeared into the heart of the kit with a soft vacuum hiss.

  "How do you know?"

  Musharraf shrugged. "It's a dog. Dogs are that way."

  We all frowned. Musharraf started running tests on the blood, humming tunelessly to himself as he worked. His DNA kit peeped and squawked. Lisa watched him run his tests, clearly pissed off that SesCo had sent out a lab rat to retest what she had already done. It was easy to understand her irritation. A centaur could have run those DNA tests.

  "I'm astounded that you found a dog in your pits," Musharraf muttered.

  Lisa said, "We were going to slag it, but Bunbaum wouldn't let us."

  Musharraf eyed her. "How restrained of you."

  Lisa shrugged. "Orders."

  "Still, I'm sure your thermal surge weapon presented a powerful temptation. How good of you not to slag a starving animal."

  Lisa frowned suspiciously. I started to worry that she might take Musharraf apart. She was crazy enough without people talking down to her. The memory addendums on the back of his head were an awfully tempting target: one slap, down goes the lab rat. I wondered if we sank him in a catchment lake if anyone would notice him missing. A biologist, for Christ's sake.

  Musharraf turned back to his DNA kit, apparently unaware of his hazard. "Did you know that in the past, people believed that we should have compassion for all things on Earth? Not just for ourselves, but for all living things?"

  "So?"

  "I would hope you will have compassion for one foolish scientist and not dismember me today."

  Lisa laughed. I relaxed. Encouraged, Musharraf said, "It truly is remarkable that you found such a specimen amongst your mining operations. I haven't heard of a living specimen in ten or fifteen years."

  "I saw one in a zoo, once," Jaak said.

  "Yes, well, a zoo is the only place for them. And laboratories, of course. They still provide useful genetic data." He was studying the results of the tests, nodding to himself as information scrolled across the kit's screen.

  Jaak grinned. "Who needs animals if you can eat stone?"

  Musharraf began packing up his DNA kit. "Weeviltech. Precisely. We transcended the animal kingdom." He latched his kit closed and nodded to us all. "Well, it's been quite enlightening. Thank you for letting me see your specimen."

  "You're not going to take it with you?"

  Musharraf paused, surprised. "Oh no. I don't think so."

  "It's not a dog, then?"

  "Oh no, it's quite certainly a real dog. But what on Earth would I do with it?" He held up a vial of blood. "We have the DNA. A live one is hardly worth keeping around. Very expensive to maintain, you know. Manufacturing a basic organism's food is quite complex. Clean rooms, air filters, special lights. Re-creating the web of life isn't easy. Far more simple to release oneself from it completely than to attempt to re-create it." He glanced at the dog. "Unfortunately, our furry friend over there would never survive weeviltech. The worms would eat him as quickly as they eat everything else. No, you would have to manufacture the animal from scratch. And really, what would be the point of that? A bio-job without hands?" He laughed and headed for his HEV.

  We all looked at each other. I jogged after the doctor and caught up with him at the hatch to the tarmac. He had paused on the verge of opening it. "Your centaurs know me now?" he asked.

  "Yeah, you're fine."

  "Good." He dilated the hatch and strode out into the cold.

  I trailed after him. "Wait! What are we supposed to do with it?"

  "The dog?" The doctor climbed into the HEV and began strapping in. Wind whipped around us, carrying stinging grit from the tailings piles. "Turn it back to your pits. Or you could eat it, I suppose. I understand that it was a real delicacy. There are recipes for cooking animals. They take time, but they can give quite extraordinary results."

  Musharraf's pilot started cycling up his turbofans.

  "Are you kidding?"

  Musharraf shrugged and shouted over the increasing scream of the engines. "You should try it! Just another part of our heritage that's atrophied since weeviltech!"

  He yanked down the flight cocoon's door, sealing himself inside. The turbofans cycled higher and the pilot motioned me back from their wash as the HEV slowly lifted into the air.

  Lisa and Jaak couldn't agree on what we should do with the dog. We had protocols for working out conflict. As a tribe of killers, we needed them. Normally, consensus worked for us, but every once in a while, we just got tangled up and stuck to our positions, and after that, not much could get done without someone getting slaughtered. Lisa and Jaak dug in, and after a couple days of wrangling, with Lisa threatening to cook the thing in the middle of the night while Jaak wasn't watching, and Jaak threatening to cook her if she did, we finally went with a majority vote. I got to be the tie-breaker.

  "I say we eat it," Lisa said.

  We were sitting in the monitoring room, watching satellite shots of the tailings mountains and the infrared blobs of the mining bots while they ripped around in the earth. In one corner, the object of our discussion lay in its cage, dragged there by Jaak in an attempt to sway the result. He spun his observation chair, turning his attention away from the theater maps. "I think we should keep it. It's cool. Old-timey, you know? I mean, who the hell do you know who has a real dog?"

  "Who the hell wants the hassle?" Lisa responded. "I say we try real meat." She cut a line in her forearm with her razors. She ran her finger along the resulting blood beads and tasted them as the wound sealed.

  They both looked at me. I looked at the ceiling. "Are you sure you can't decide this without me?"

  Lisa grinned. "Come on, Chen, you decide. It was a group find. Jaak won't pout, will you?"

  Jaak gave her a dirty look.

  I looked at Jaak. "I don't want its food costs to come out of group bonuses. We agreed we'd use part of it for the new Immersive Response. I'm sick of the old one."

  Jaak shrugged. "Fine with me. I can pay for it out of my own. I just won't get any more tats."

  I leaned back in my chair, surprised, then looked at Lisa. "Well, if Jaak wants to pay for it, I think we should keep it."

  Lisa stared at me, incredulous. "But we could cook it!"

  I glanced at the dog where it lay panting in its cage. "It's like having a zoo of our own. I kind of like it."

  Musharraf and the Pau Foundation hooked us up with a supply of food pellets for the dog and Jaak looked up an old database on how to splint its busted bones. He bought water filtration so that it could drink.

  I thought I'd made a good decision, putting the costs on Jaak, but I didn't really foresee the complications that came with having an unmodified organism in the bunker. The thing shit all over the floor, and sometimes it wouldn'
t eat, and it would get sick for no reason, and it was slow to heal so we all ended up playing nursemaid to the thing while it lay in its cage. I kept expecting Lisa to break its neck in the middle of the night, but even though she grumbled, she didn't assassinate it.

  Jaak tried to act like Musharraf. He talked to the dog. He logged onto the libraries and read all about old-time dogs. How they ran in packs. How people used to breed them.

  We tried to figure out what kind of dog it was, but we couldn't narrow it down much, and then Jaak discovered that all the dogs could interbreed, so all you could do was guess that it was some kind of big sheep dog, with maybe a head from a Rottweiler, along with maybe some other kind of dog, like a wolf or coyote or something.
