Chapter 1: It's Not a Virus
The evacuation sirens in Port Ashgrove stopped at 4:52 in the afternoon, which was how you knew the people running them were either gone or dead.
You noted the time on the whiteboard anyway, under the column you had labeled HOST BEHAVIOR in neat block capitals three days ago, back when the Lindqvist Institute still had a director, a cafeteria, and a security guard named Marcus who brought you clementines. The column had gotten long. The handwriting had gotten worse.
Behind the glass of the containment suite, sample 7-C pressed its pale, ribbed body against the wall of its petri dish and rippled toward the heat of your hand.
"Don't flatter yourself," you told it. "Everybody does that."
The lab was on the fourth floor, BSL-3 with ambitions, and you had sealed it yourself at noon when the last of your team climbed into a National Guard truck and begged you to come with them. You had said you would follow in an hour. You had said it the way people say it to telemarketers. Seven samples of a parasite that should not exist were sitting in your incubators, and four of them were still alive, and if the city burned tonight the only living specimens on the West Coast would burn with it.
So you stayed. You ate vending machine pretzels. You talked to a worm.
At 5:10 the elevator dinged.
You froze with a pipette in your hand. The elevators had been locked down. You had locked them down. You turned, very slowly, toward the airlock window, and watched a man step out into the corridor with a pistol raised in a two-handed grip, checking corners like he had done it ten thousand times and found something terrible in at least half of them.
He was tall, broad through the shoulders, in a dark tactical jacket over a gray henley and a holster rig that looked like it had opinions. His hair was the color of wet sand and fell into his eyes in a way that had to be a deliberate choice, because no one with that jaw left anything to chance. There was a two-day beard on him and a cut over one eyebrow that someone had closed with a butterfly strip and then ignored.
He reached the airlock, saw you through the glass, and lowered the gun about three inches.
You pressed the intercom. "This is a sealed laboratory."
"I gathered." His voice came through the speaker tinny and dry. "Doctor, I'm going to need you to open the door."
"Who are you?"
"Leon Kennedy. DSO." He held a badge up to the glass. You squinted at the eagle, the seal, the tired face in the photo. "Division of Security Operations. I report to the President, which sounds more impressive than it is. You're the parasitologist."
"I'm a parasitologist."
"You're the one who wrote the report." He tucked the badge away. "Forty pages. Somebody in Washington read the summary, panicked, and called me. Now I'm here, and you're coming with me."
"I'm not leaving my samples."
He looked at you for a long moment through two inches of laminated glass. You had the uncomfortable sense of being assessed by someone who did it professionally, a threat check and a medical check and a stubbornness check all folded into one blink.
"Okay," he said. "Bring them."
That was not the argument you had prepared for. You opened the door.
He did not touch anything, which you appreciated, and he did not stand too close, which you appreciated more. He walked the perimeter of the lab with his gun lowered but not holstered, glancing into the cold room, the autoclave alcove, the window that looked down on the empty parking lot where your car was still parked crooked. Then he came back and stopped in front of the containment suite and looked at sample 7-C for a long time.
It rippled at him.
"Huh," he said, flat as a sidewalk. "Hi again."
"You've seen this before."
"Something like it." He didn't take his eyes off the dish. "Spain, a long time ago. A village where everybody had one of these in their spine. They called them Las Plagas." A muscle in his jaw went tight and then let go. "I've been tracking the black market for samples ever since. Somebody sold one to somebody, and that somebody put it in your city's reservoir."
"The Ashgrove intake on Tuesday," you said. "I know. I sequenced it." You pulled your laptop around and turned the screen toward him. "It's been modified. The original Plaga needed direct injection or ingestion of eggs. This one has a free-swimming larval stage. It survives in chlorinated water for up to seventy hours and enters through the gut lining."
He leaned in. He smelled like gun oil and rain and the inside of a car that had been driven very fast. "So it's a virus that swims."
You closed your eyes.
"It is not a virus."
"It spreads like one."
"So does gossip. Gossip isn't a virus either." You opened your eyes again and found him watching you, the corner of his mouth doing something small. "A virus is a strand of genetic material in a protein coat. It can't reproduce on its own. It doesn't have a nervous system. It doesn't," you jabbed at the screen, "grow tentacles out of a man's collarbone and use them to open a car door. This is a multicellular eukaryotic parasite with a functional ganglion. It's an animal, Agent Kennedy."
"Leon."
"It's an animal, Leon."
"Noted." He straightened up. "Does the animal have a weakness?"
"Light," you said, and some of the tension went out of your shoulders, because this part you knew cold. "Intense light. The adult form is photophobic. A flash at close range overloads the ganglion and forces it out of the host's body to escape, at which point it's exposed and very easy to kill."
"Flashbangs," he said. "Yeah. I figured that one out the hard way."
"Then you did it right by accident."
"Story of my life." He checked his watch. "Pack what you need. We've got a helicopter coming to the rooftop of the federal building on Third in ninety minutes, and the streets between here and there aren't friendly."
You started pulling samples into a transport cooler, moving fast, hands steady in a way they had not been since Tuesday. Then you stopped.
"How did you get up here?" you asked. "I locked the elevators."
"Somebody unlocked them." He was at the window now, looking down. "Card reader in the lobby showed a valid access badge about twenty minutes before I got here. I figured it was you."
"I haven't left this floor since noon."
Leon turned around.
Somewhere below you, in the stairwell, a door banged open against a wall.
There were six of them, and they came up the stairs the way water comes up a drain, all at once and from below. You heard them before you saw them: the scrape of shoes, a man's voice saying something in a language that was not quite English and not quite anything, a low wet clicking like a tongue against teeth.
"Behind me," Leon said. "Close the cooler."
You closed the cooler. He was already moving. He kicked the lab door shut, threw the deadbolt, and shoved a steel cart in front of it, and the first body hit the door a second later hard enough to rattle the glass in the observation window.
You saw a face through it. You knew the face. It belonged to Marcus, the security guard who brought you clementines, and his eyes had gone a flat, dull red like a coal under ash, and there was a dark line running up the side of his neck under the skin like a vein that had decided to go somewhere else.
"Oh," you said, very quietly. "Oh, no."
"You know him?"
"He works here." You swallowed. "Worked."
Leon did not say I'm sorry. He did not say anything at all for a second, just looked at Marcus through the glass with an expression you would think about later, something old and worn-in, like a coat he had put on too many times. Then he pulled a cylinder off his belt.
"How close is close range?" he asked.
"What?"
"For the flash. You said close range. How close?"
"Within two meters for a full ganglion overload," you said automatically. "Beyond that you'll stun the host but the parasite stays seated."
"Two meters." He nodded once. "Great. Get down and cover your eyes."
The door gave.
What happened next happened in pieces. Marcus came through first, and then a woman in a nurse's scrubs, and then a man whose jaw hung loose in a way that made your stomach drop. Leon let them come. He let them come right into the room, past the cart, past the edge of the bench, close enough that you could smell copper and pond water, and only then did he pull the pin and toss the grenade underhand into the middle of them and turn his face away.
The world went white.
You had covered your eyes and still saw the bones in your fingers. The bang hit you in the sternum. When you could see again, three of the hosts were on their knees and the backs of their heads were opening like seed pods, pale tendrils whipping blindly at the air, and Leon was already firing, precise and unhurried, one shot each.
The other three were still standing.
"Those ones were too far back," you shouted over the ringing in your ears.
"Yeah," Leon said. "I noticed."
He went for them with the knife. You had seen fights in movies. This was not like that. It was quiet and ugly and over in about nine seconds, and at the end of it Leon was breathing hard and there was a long tear in the sleeve of his jacket and something dark on the floor that was still twitching.
He turned around. "You okay?"
You were on the floor with your back against the bench and the cooler hugged to your chest. Your heart was trying to come out through your ears.
"The parasite you just stabbed," you said, "was a juvenile. You can tell by the coloring. If juveniles are already in the hosts, the incubation period is shorter than I estimated, which means my model is wrong, which means the evacuation perimeter is wrong."
Leon stared at you.
"You're welcome," he said finally.
"Thank you," you said. "You're bleeding."
He looked down at his arm as if it belonged to someone else. "Huh. So I am."
You got up, legs shaking, and pulled a first aid kit off the wall, and he let you cut the sleeve away and look. It was shallow. You cleaned it anyway. He held very still while you worked, watching your hands instead of your face, and when you pressed the gauze down he let out a breath through his nose that might have been a laugh.
"What?"
"Nothing. Most people who see that," he tipped his head at the bodies, "don't go straight to incubation periods."
"Most people don't have a forty-page report due."
"Your report's done. I read it on the plane."
"Then I need to write an addendum." You taped the gauze. "Did you understand any of it?"
"About a third." That small thing happened at the corner of his mouth again. "The third with the pictures."
You were about to tell him what you thought of that when your phone buzzed in the pocket of your lab coat.
You pulled it out. One new message. The number was saved in your contacts, though you had not seen it light up in eleven months, not since the funeral, not since you had stood in the rain while they lowered a closed casket into the ground and told yourself the lab fire had been an accident.
DR. E. HALVORSEN: You always did keep the best samples for yourself. Come home, Doctor. I'll leave the light on.
You must have made a sound, because Leon was suddenly beside you.
"Who is it?"
You turned the phone so he could see.
"My mentor," you said. "He's been dead for almost a year."
