Read Chapter 17: The Infection Spreads

The coach had become a fever ward. Élise counted the bodies as she moved down the aisle—not corpses, not yet, but people bent over in the grip of something that turned their lungs to glue. A woman with blood seeping from her nostrils pressed a torn shirt to her face, the fabric already sodden. Two rows back, a man clawed at his own throat, fingernails leaving red furrows as he tried to find air that wouldn't come.

Twenty cases had become fifty in the space of ninety minutes.

"Fifty-three confirmed symptomatic," Pierre said, catching up to her at the rear of the coach. His voice was low, meant only for her. "Twelve of them hemorrhagic. That's not the progression we saw in the first wave."

Élise pulled the filtered mask down from her mouth just enough to speak. "The first wave had one point of exposure. This is different. Whatever Antoine released, it's mutating faster inside human hosts than the original strain."

"Or it was always this fast and the first passengers just took longer to show symptoms."

That was worse. That meant they were sitting on a bomb with no timer and no idea how much time they had left.

"Is Renaud still in the staff room?"

"Locked in." Pierre glanced toward the forward corridor. "He told Ahmed he's 'monitoring the situation from a safe vantage point.' Those were his exact words."

Of course they were. A bioweapon test doesn't care if its subjects panic, but it does require its observer to survive long enough to record the results.

"I need to see Marcel."

Pierre's face tightened. "Élise, the man's barely holding himself together as it is. The passengers can hear him at the end of the car. He's not exactly reassuring."

"Good. Panic gets results."

She found Marcel where she expected him—in the small crew alcove at the head of the first-class coach, a half-empty bottle of water trembling in his hand. His face was grey, the color of a man who hadn't slept in two days and had run out of reasons to pretend he had.

"You need to tell them," Élise said without preamble.

Marcel looked up at her, eyes hollow. "Tell them what? That we're all going to die in a tube under the sea?"

"No. Tell them the truth about why we're still here."

"I don't know why we're still here. No one tells me anything." His voice cracked. "I'm just the driver. I drive the train. That's all I do. I press buttons. I open doors. I don't know anything about—" He gestured vaguely toward the fevered passengers beyond the window.

"But you do know something." Élise sat down across from him, forcing her voice low and even. "You know why we haven't been rescued. You know why there's been no news, no helicopters, no emergency protocols. I've asked. There's been nothing. Forty-eight hours in a tunnel with a sick train and not a single external contact. That doesn't happen unless someone wants it to happen."

Marcel's hands tightened around the bottle. His knuckles went white.

"I want to help you," Élise continued. "But I can't help you if you're still lying to me."

The silence stretched between them, broken only by the distant sound of a passenger coughing—a wet, retching sound that seemed to go on too long.

"Renaud," Marcel finally said. "He came to see me before we left Paris. Told me there'd been a credible threat against the train. Said I was to follow his orders exclusively, no matter what radio traffic suggested. That help would come when he said it was safe."

"And?"

Marcel's laugh was bitter. "There's no credible threat. There's no rescue plan. I've been trying to raise Eurotunnel control for twenty hours. All I get is static and a recording telling me to stay calm." He reached into his jumpsuit pocket and pulled out a handset the size of a brick, its casing scuffed and battered. "This is all I have left. Renaud thought I didn't know about it. Emergency channel. Not connected to the main comms—a direct line to a government office in Paris. They told me to sit tight, that a team would be dispatched."

"When?"

"That's the thing." Marcel's eyes met hers, and she saw the weight of his confession settling into them. "They've known the casualty figures since the first hour. They told me to report a lower number to any passengers who asked. To keep the death count a secret."

"How many deaths?"

"Fourteen." His voice dropped to hardly more than a whisper. "Fourteen people have died on this train, Dr. Fournier. Not from the virus—from a stampede at the beginning, trying to get away from the first sick passengers. Crushed against the doors. And we've been reporting three. Blamed it on pre-existing conditions."

Élise felt the floor shift beneath her, though the train was motionless. "The passengers don't know how many people are actually dead?"

"The passengers aren't the problem. It's the people outside." Marcel gestured vaguely upward, toward the tunnel roof and the sea beyond. "They think this is contained. They think there's two dozen sick, not—" He gestured toward the car behind them. "Not this."

The truth of it hit her like a physical blow. Renaud wasn't just running a test in isolation. He was running a test with a story attached—a clean narrative, a controllable casualty count, a version of events that could be managed after the fact. Fourteen dead from panic didn't fit the narrative. Fifty-three sick didn't fit. What would fit was a tidy number, a contained outcome, a "successful quarantine" that could be reported without embarrassing anyone.

But if the virus spread and half the train died, the story would unravel. And Renéant had already shown he was willing to kill people to keep his operation secret.

"I need to contact the outside," Élise said. "Now. Before this gets worse."

Marcel looked at the emergency phone in his hands, then at her. Something shifted in his expression—a decision, a surrender, an acknowledgment that he was already in too deep to go back.

"There's one contact programmed." He handed her the phone. "I don't know who it belongs to. I was told to only call if the train was hopelessly compromised and to describe the situation as 'fully contained' or 'fully breached.' No other options were acceptable."

Élise took the phone. It was heavier than she expected, warm from Marcel's grip. A single button on the face, marked only with a symbol she didn't recognize—but the code underneath it made her breath catch.

77-CH-4-V.

The same code as the pathogen ampoule. The same code as the satellite phone she'd found on the dead DGSI agent.

This wasn't a line to Eurotunnel or the French government. It was a direct line to the people running the operation.

"Don't call it," she said. "Not yet. They'll know something's wrong if you break protocol."

Marcel nodded slowly, his face pale. "Then what do we do?"

Élise looked down at the phone in her hands, weighing its possibilities. Whatever was at the other end of that line, it was the only connection they had to the world above. And if Renaud was the kind of man who would hide the death count of his own passengers, there was no telling what a call to his masters might unleash.

"I'll find Antoine," she said. "But first—"

A scream cut through the carriage. A woman's voice, raw with terror. Élise was moving before she'd finished the thought, Marcel scrambling to keep up.

At the far end of the car, a passenger had collapsed in the aisle, his body contorted, blood streaming from his eyes, ears, and mouth. The hemorrhagic presentation. Only this was faster than any case Pierre had charted. Seconds, not hours.

A man beside him bent to help and recoiled, his hands already stained red.

"It's getting worse," Marcel whispered.

Élise looked down at the emergency phone, then at the dying passenger, then at the long line of frightened faces pressing close to see what had happened.

They had maybe hours before this train became a tomb. And the only person who might have the answer was currently hiding somewhere in the guts of the Channel Tunnel with a vial of engineered virus and a counter-serum that might not even exist.

She pocketed the phone and began to push through the crowd toward the ventilation shaft access. She wasn't going to wait for help that had never been coming.
