Parasite (Parasitology) (8 page)

“Sal?” said Nathan, from the office doorway. “You ready?”

“I’m coming.” I straightened, smiling again. “Let’s eat.”

Nathan clicked the office lights off as he stepped out to the hall. The lights in the terrarium stayed on, casting a bloody red glow over everything. I grabbed my bag from the chair and followed him into the hall, leaving the silently growing plants behind.

The Indian restaurant we wound up in was half a mile from the hospital, tucked into one of those odd warrens of half-residential, half-commercial streets that seemed to spring up all
over San Francisco. Every neighborhood had its own character, a mixture of city natives, transplants, and people who thought of themselves as just passing through, even though they’d been living there for longer than I’d been alive. On such blends are cities built.

Nathan took a sip of his mango lassi as he looked thoughtfully at his goat curry. I leaned over and poked him in the arm with my fork. He looked up, startled.

“What?”

“We’re supposed to be having lunch together, but I don’t know where you are,” I said. “What’s on your mind?”

An odd look crossed his face. Putting down his lassi, he reached up and adjusted his glasses—a sure sign that he was uncomfortable. “Did you know that curry powder is a natural antiparasitic? That’s probably part of why it was originally so popular in Indian cuisine. India has a warm, moist climate. That encourages high levels of parasitism, and the more parasites you have, the more ways you’ll need to keep them out of your population. Assuming you want to have a healthy population, that is.”

“And it’s not until recently that we’ve been put into the position of needing to
add
parasites for the sake of our health, rather than getting rid of them,” I said. “I know. You tell me things like that every time you don’t want to talk about what’s really on your mind. It’s a good thing I was never enthusiastic about developing a taste for sushi. I think you’d get us kicked out of any sushi restaurant worth visiting.”

“Just because people don’t want to consider the risks inherent in their food choices—”

“Nathan, what’s
wrong
? You don’t usually try to change the subject twice in one meal.”

He paused before sighing heavily. “If I say you really don’t want to know, Sal, will you believe me?”

“Yes, but I won’t stop asking.” I poked him with my fork
again. This time the action earned me a brief smile. “I would be a terrible girlfriend if I didn’t make you tell me what was on your mind. You listen to me whine about dealing with SymboGen enough. I can listen to you.”

“It’s about what happened last night.”

The words were simple, but still sent a thread of unease into my guts, where it curled and twisted like a parasite in its own right. Last night he’d been dealing with an accident. I hated hearing about accidents… but this was Nathan, and he deserved better than me shutting him out because I was uncomfortable. “I’m a big girl,” I said. “I can handle it.”

He sighed again. This time he took off his glasses, polishing them on the tail of his shirt as he said, “It was a nine-car pile-up on the Bay Bridge. The people who made it as far as the hospital said they had no warning at all. One minute, traffic was moving normally. The next, a big rig was jackknifing to block all four lanes of traffic, and cars were slamming into it before they had a chance to realize what was about to happen to them. Eleven people died before emergency services could even get to the scene.”

“That’s horrible,” I breathed, feeling the unease twist harder in my stomach. It was horrible, yes, and it involved a car crash, which was normally enough to make Nathan reluctant to discuss his work with me. But was it horrible enough for him to be
this
reluctant?

I didn’t think so.

Nathan heard my confusion. He looked up, putting his glasses back on, and said, “You said you were going to the mall with your sister yesterday. In San Bruno. Where those people started sleepwalking.”

“Yes. Joyce and I were both there. But what does that have to do with anything?”

“The driver of the big rig survived. So did the driver of the bus that capped off the accident. His passengers—the ones who
lived—said he hit the gas when he came around the curve on the bridge and saw the wreckage. Not the brakes. The gas.”

The similarity to my own accident made me go cold. “What are you—”

“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.

T
he 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.
