Parasite

  “Both drivers are showing the same symptoms as the people from the mall. They’re walking in their sleep. And apparently, causing multi-car pile-ups in their sleep, too. The trucker had no passengers, but the people on the bus said that their driver was perfectly normal when they first got on. He took their fares, said hello, asked about their families… some of them had been riding with that driver for years. They said he seemed perfectly normal, right up until he stopped responding to questions. The accident happened a little bit after that.”

  I didn’t know what to say, and so I didn’t say anything at all. I just stared at him, trying to formulate the words that came next. I couldn’t find them.

  Nathan nodded, seeming to understand my silence. “More than half the people who were in the accident didn’t make it out of the ER. Some of the others will never be the same. That doesn’t even go into the ones who won’t wake up.”

  “There’s more than just the drivers?” The question came out in a whisper.

  “Two from the bus, a few passengers from the cars—it’s hard to tell ‘sleepwalking, won’t wake up’ from ‘genuine coma’ right now. You were in a coma. You came out of it.” Nathan paused, wincing. “Oh, hell. Sal, I didn’t mean to…”

  “It’s okay. I asked, remember? And I know my coma didn’t end the way the original Sally might have wanted. I wanted to be supportive.” My stomach was still rolling. I pressed my hand flat against the skin above my navel, grimacing. “Maybe I was a little too supportive. I’ll have to remember that for next time.”

  “Thank you for trying.” He reached across the table to take my free hand. “Even a little supportive is good enough for me.”

  “Don’t say that. I’m still learning social norms, remember? You tell me I don’t have to support you to the best of my ability, next thing you know, I’m not showing up for dates anymore, and I keep asking you to do my laundry.”

  A small smile creased the corners of his mouth. “I think that’s kids coming home from college.”

  “Or working as biotech interns. I have just described my sister, only substitute ‘dinner’ for ‘dates.’ ”

  “Good, because I don’t want to date your sister, and I don’t want to think about you dating your sister, either.”

  I burst out laughing, earning myself a startled glance from the people at the next table over. “Now that would definitely be going against social norms.”

  “Very true.” Nathan released my hand and looked at the remains of our lunch. Neither of us had cleaned our plates. “Are you going to eat anything else?”

  With how upset my stomach was, I wasn’t sure I was going to keep down what I’d already eaten. “No,” I said. “Can we go for a walk?”

  “Sure,” he said, and signaled for the check.

  I leaned back in my chair and tried to smile, despite the fact that I really felt like I was going to throw up at any moment. The check came quickly, and Nathan paid. Pushing the feeling of roiling unease aside, I took Nathan’s hand, and we walked together out into the early afternoon sun.

  Every six months or so, some conspiracy nut starts in with “what they aren’t telling you” and “these are the things they don’t want you to know,” and you know what? Not one of them has produced verifiable scientific evidence that the Intestinal Bodyguard™ is harmful in humans. Not one! Don’t you think that if there were some kind of negative side effect, we’d have seen it by now? I don’t mean to sound like I’m claiming nothing can ever go wrong—we’re all human at SymboGen, we make mistakes—but even if you’re into conspiracy theories, you’ve got to admit that it’s pretty far-fetched to believe that we could somehow suppress every possible bad effect of the Intestinal Bodyguard™. Millions of people have our implants. Millions. That’s not a small number, and those people talk. We couldn’t keep them all quiet if we wanted to.

  And why would we want to? Look at the blogs, look at the social media updates! No more allergies, no more missed medication—heck, some people even claim their Intestinal Bodyguards™ guard against hangovers. Now, that’s not a feature that we were necessarily aiming for, and it’s not in the brochure, but if your implant wants to help you have a little more fun, I say go right ahead. What’s the harm?

  Steve’s initial proposal was as fascinating as it was flawed. He wanted to take D. yonagoensis—a type of tapeworm that parasitizes fish in its natural environment, using small crustaceans as a secondary host—and use it to design a sort of “super tapeworm,” a specially crafted hybrid that would enhance the human immune system, protect against allergies and autoimmune conditions, and die every two years. That way, it would be the perfect pharmaceutical tool, but it wouldn’t put the entire pharmaceutical industry out of business. I won’t pretend that he wasn’t thinking about the profits. We all were. Money makes the world go ’round.

  It’s a pity, really, that the design for his D. yonagoensis was never going to be viable. He used too many genetic strains, blending them without a cohesive core. The entire plan was flawed from the start. It couldn’t have worked.

  That’s where I came in.

  AUGUST 2027

  The Embarcadero encompasses a series of grassy lawns and jogging paths along the San Francisco Bay. It’s one of the most scenic places in an already beautiful city, and even on a workday afternoon, it was decently crowded with a mix of tourists and natives. The sky was a flawless blue, the color of surgical gloves, which probably had something to do with the size of the crowd. There’s something about a beautiful day that just encourages trips to the seaside, even when the seaside is only a few blocks from your office. Maybe especially when the seaside is something you can see from your window while you’re pretending to care about work.

  Nathan and I walked along a stretch of grass near the street, close enough to each other that we didn’t feel like we were in danger of getting separated by random joggers, far enough apart that we could enjoy the day on our own terms. Nathan liked to look at the ground as he walked, watching for interesting plants and examples of the increasingly rare local wildlife. I preferred looking at the sky. Somehow, the endless blueness of it all never stopped amazing me.

  A man jogged by with a black Lab at the end of a nylon leash. The dog looked miserable, dragging her feet and carrying her tail tucked low between her legs. I stopped walking to watch them go by. “That’s weird…”

  “What?” Nathan stopped in turn, turning to face me. “Sal?”

  “Did you see that dog? The black Lab?” I pointed after the man and his dog. Well, presumably his dog. A dognapping could explain the animal’s distress, which was only growing as the pair moved on. Now she was visibly pulling against the leash, trying to get away. “You never see a Lab that unhappy. They’re the best-natured dogs in the world. That’s why they wind up being used as service animals so often.”

  “You can’t save every animal you think might not be optimally happy, you know.” Nathan squeezed my shoulder. “I wish you could, but you’d run out of room at the shelter before you ran out of animals that needed help. I run into something similar with patients. I want to help them all. I can’t.”

  “Time and insurance are cruel masters,” I said automatically. I still couldn’t take my eyes off the dog. The jogger had stopped and was scolding his pet now, although they were too far away for me to hear what he was saying. The dog pulled harder on her leash, and barked, once. That sound was loud enough to carry, and several other heads turned toward it. Dogs barking in the city wasn’t anything unusual. Dogs barking in that much evident distress was.

  Maybe we weren’t the first ones to witness what happened next; maybe other people saw it happen before we did. But those people didn’t tell anyone what they’d seen—maybe didn
’t understand what they’d seen—and we did. That made all the difference in the world.

  First the jogger dropped the leash. It fell to the grass, and the dog ran several yards before turning back to face her master, barking again. She was a good dog. I could tell she was a good dog, even without knowing her name or why she was so unhappy. A bad dog would have run as soon as she had the chance. This dog looked back to her master, waiting for whatever was wrong to go away and leave things the way they were supposed to be. I abandoned all thoughts of a dognapping when I saw the look the dog was giving to that man, to her man, as she waited for things to fix themselves.

  The man didn’t move. For several seconds, he didn’t move at all. Then all the tension went out of his shoulders and neck, leaving his head to loll limply forward. Several more seconds passed. Nathan’s hand tightened on my shoulder.

  “I don’t like this, Sal,” he said. “Whatever this is, I don’t like it. We should get out of here.”

  “But the dog—”

  “Will be fine.”

  “What if he’s having a seizure or something? Shouldn’t you see if you can help?”

  Nathan shook his head. “This doesn’t look like the start of a seizure. I don’t know what it is, but it could be viral, and it’s not something I’m equipped to deal with.”

  The man raised his head.

  The dog immediately started barking again, her ears going flat against her head and her posture going rigid, something I recognized from the shelter as a sign that she was about to attack. Without thinking about it, I put two fingers in my mouth and whistled. Her head whipped around, ears going back up, and she broke into a sudden run, heading straight for us.

  “Oh, crap, she’s going to attack!” said Nathan, and pulled me backward, seeming set on physically removing me from the scene if that was what it took to keep me from getting savaged.

  I pulled my shoulder out of his grasp. “No, she’s not,” I said, and dropped into a crouch just as the dog reached us. She practically flung herself into my arms, whining frantically. She stank of urine, a hot, acrid smell. At some point during the confrontation with her master, she must have pissed herself.

  “What did he do to you?” I muttered, and raised my head, intending to give the dog’s owner a piece of my mind. Then I froze, arms tightening around the still-whimpering dog. She plastered herself hard against me, like she thought she could somehow protect us both by cowering just a little more thoroughly.

  The man—her master—was walking toward us with his arms held out for balance, a blank look on his utterly slack face. He looked like the people Joyce and I had seen at the mall; he looked like he was sleepwalking. All around us, people were shouting and pointing at him. Many of them were filming his shambling approach with their phones. The footage would be all over the Internet before the news crews even showed up.

  This time, when Nathan pulled on my shoulder, I didn’t pull away. Instead, I scrambled to my feet, grabbing the dog’s leash at the same time. She whined, but she came willingly as the three of us turned and ran, as fast as we could, away from the Embarcadero.

  We arrived back at the hospital winded and sweaty, having run the first two blocks and walked the rest. Only the dog seemed unaffected, probably because she belonged to a jogger—keeping up with me and Nathan had to seem like a walk in the park to her.

  Just thinking the word “park” made that uneasy feeling in my gut reappear. I staggered to a stop just inside the lobby, catching myself against the wall with my free hand as I gasped for air. The dog sat down by my feet, assuming the patient waiting posture that has been the characteristic of the Labrador retriever since the breed was born.

  Nathan stared at the closed door, and then turned to stare at me. “Did you see that?” he asked needlessly. I looked at him without saying a word. He grimaced. “I’m sorry, I know you saw that, of course you saw that, but that was—he was perfectly normal, and then he was just…”

  “Gone,” I whispered. I pushed away from the wall and knelt next to the dog. She had a full set of tags. I dug through them until I found the one with her name. “He was gone, and Beverly here was all alone. Weren’t you, Beverly?”

  The dog—Beverly—looked up at me with warm, trusting brown eyes. I was a human. I had her leash, and I knew her name. Clearly, I was going to make everything okay. It must be nice to be a dog.

  “I have to notify the ER. They need to send someone to pick him up…” Nathan raked a hand through his hair before whipping around to look at me. “Can you wait in my office for a few minutes? I promise, I’ll be there as fast as I can.”

  “Right now, I’m not going anywhere that isn’t in this hospital, and neither is Beverly,” I said, and straightened.

  Any protest Nathan might have been considering died when he saw the way I was holding the leash. He nodded. “Okay. I’ll be right there. I love you.” He kissed my cheek, and he was gone, speed walking toward the nearest set of doors.

  The nearest security guard frowned in my direction as soon as Nathan was out of sight. I was disheveled, and I was with a dog who didn’t have a service jacket on. I offered the woman a wavering smile and turned to walk quickly toward the nearest bank of elevators, hoping that she’d let me go off and become someone else’s problem.

  Luck, or maybe laziness, was with me; the guard kept glaring until I was safely in the elevator and bound for Nathan’s floor. Beverly walked easily on her leash, with none of the pulling or foot-dragging that I’d witnessed when she was being walked by her owner; she even heeled naturally, settling against my leg like she’d been born there.

  “You’re a good dog, aren’t you, Beverly?” I asked her. “You’re a good, good dog. A good dog like you shouldn’t be treated like that. I’ll make sure it doesn’t happen again. You have my word on that.”

  Beverly turned her big brown eyes on me and believed every word I said. I could see it in her face, and belief is in the nature of dogs.

  The elevator let us out on Nathan’s floor, where everyone was much more familiar with me, and hence more inclined to be forgiving. Nathan’s research assistant, Devi, still raised an eyebrow at the sight of my new black shadow. “Sal, I don’t mean to sound like I’m prying here, but… is that a dog?”

  “She’s a dog,” I confirmed needlessly. “Beverly, I want you to meet Devi. Devi, this is Beverly. She joined us in the park.”

  “It’s nice to meet you, Beverly,” said Devi to the dog, as politely as if she were addressing a human. Her eyes flicked back to me. “Still not trying to pry, but you look a little flushed. Can I get you a glass of water or something?”

  The unspoken Are you okay? in her words was loud enough that she might as well have said it. I mustered a smile and said, “A glass of water would be good.” A fainting couch would be better, but if I asked for that, I was going to find myself getting more medical attention than I wanted—and there was no telling what would happen to Beverly, who really wasn’t supposed to be in the hospital.

  “Uh-huh.” Devi rose, still watching me. “Are you going to tell me why you look so tired, or are you going to let me spin wild stories to amuse myself? You’re secretly an international spy who’s been faking amnesia while you waited for your contact to meet you with the goods.”

  “ ‘The goods’?” I echoed.

  “You know. Information that can be used to prevent the next World War.” Devi walked into the small nurse’s closet behind the desk as she spoke, and called back, “It’s probably on a thumb drive hidden inside the dog. That’s why you have her, right?”

  I’d seen enough bad spy movies to know where Devi was going with this, and decided to play along. It would make us both feel better. “Yes, but I’ve decided to abandon my mission,” I deadpanned. “I just can’t bring myself to cut open a dog to get to the secret plans.”

  “That’s what makes you a better person than your government masters.” Devi emerged with a bottle of red Gatorade. I wasn’t sure whether it was the red kind t
hat supposedly tasted like fruit punch or the red kind that supposedly tasted like cherry. I also wasn’t sure it mattered. I was thirsty enough that the first half of the bottle didn’t taste like anything but sweetness. By the time the first traces of artificial fruit came creeping in, the dryness in my throat was mostly gone, and Devi was no longer watching me like she was afraid I’d keel over at any moment.

  “Thank you,” I half-said, half-gasped, and replaced the lid on the bottle. “I think I needed that pretty bad. We saw—”

  The image of the man in the park—Beverly’s real master, even if she had abandoned him for me—as the animation drained from his face rose behind my eyes. My stomach gave a lurch, objecting to the memory more than to the Gatorade. The result was the same. I clapped a hand over my mouth, thrusting Beverly’s leash into Devi’s hands. Devi looked unsurprised. She took the leash and stepped aside, clearing the way for me to race to the bathroom.

  Red Gatorade looks a lot like blood when it’s filling a toilet basin. I stayed on my knees in front of the bowl, bracing my hands against the floor while I waited for my head to stop spinning. My stomach gave another lurch. I managed to flush away the mess before I threw up again, but barely.

  At least this time, there was less artificial red in the bowl. I leaned to the side and pressed my forehead against the tile wall, waiting for the urge to vomit a third time to pass. It went slowly, but it went, and I stood on legs that felt like they were made of rubber. Once I was sure they’d hold me, I staggered to the sink and washed my face with icy water. I only wished there were a way for me to wash away the memory of what I’d seen. That poor man…

  I shuddered. Then I straightened, dried my face with a paper towel, and walked back out of the bathroom to rescue Devi from Beverly.

  Devi turned out not to need much rescuing. She was back behind her desk, and Beverly was sprawled at her feet, looking like she belonged exactly where she was. I laughed a little, despite the ongoing lightness in my head.
