Read Chapter 16: The Missing

The roar came before the warning. One moment Félix was crouched by the timber, tapping its base with his pick, humming some tune from his village that Émile had grown sick of hearing. The next, the chalk above him groaned like a dying animal, and the ceiling came down in a white avalanche.

Émile moved without thinking. He had his hands on Félix's shoulders and was dragging him backward before the dust had finished blooming. But Félix had been kneeling in the wrong place—the place where the old timber met the sagging roof—and the collapse had caught him from the waist down.

He screamed once, not a word, just a sound that belonged in a slaughterhouse. Then the dust filled his throat and he coughed instead, spraying pink spit over his own hands.

"Petit!" Émile shouted. "The braces! Now!"

Petit was already moving, dragging fresh timbers from their dwindling supply. The other two—a quiet Basque called Lhande and a Parisian thief named Gérard—threw themselves against the wall where the chalk had begun to weep a steady trickle of white powder, as if the earth were bleeding sand.

Brandt the chaplain stood in the tunnel's mouth, his hands folded across his stomach, his blue German eyes unreadable. He had stopped offering prayers three days ago. Now he just watched.

Émile dug. He dug with his hands, then with a spade that Petit shoved into his grip, and the chalk came away in wet, crumbling chunks. Félix's voice came up through the rubble, muffled and strange.

"I can see them."

"You can see nothing," Émile grunted. "Keep your head down. We'll have you out—"

"No, listen." Félix's hands emerged from the white, scrabbling at the air. His fingers closed on Émile's wrist with surprising strength. "There's a chamber. Side-cut. They're in there, Émile. All of them."

"Who?"

"The wounded. French. German. A priest—no, two priests. One with a red cross on his arm." Félix's eyes were wide and unblinking, his face caked with chalk dust so that he looked like a statue come briefly to life. "They're just sitting there. They're not fighting. They're just sitting there and dying."

Petit crossed himself. Lhande looked away.

"Félix," Émile said, keeping his voice low and even, the way his father had talked to a spooked horse in the mines, "you're buried. Your head is telling you things because the weight is on your chest. It's a dream, Félix. A waking dream."

"I know what I saw." Félix's grip tightened. "There's a door. Green. Rusted. Painted with crosses—the old kind, the equal-armed ones. It's behind them. If I can get to it, I can open it. I can let them out."

"I'll get to it," Émile said. "Just tell me where."

"Side-cut. Three meters along the left wall of this gallery. But the timber's rotten. It'll fall on your head if you go past it." Félix coughed, and blood flecked his lips. "You'll need to widen the space where I'm stuck. I can fit through. I'm smaller than you."

He wasn't smaller. Félix was built like a draft horse, with shoulders that barely fit through the standard galleries. But Émile didn't argue. He dug faster.

The chalk came away in slabs now, loosened by the collapse. Petit worked beside him, and together they exposed Félix's torso, then his hips. The timber that had caught him lay across his thighs at an angle, and the wall had sagged inward, pinning him like a vice.

"We'll need to cut it," Petit said. "The timber's live. If we shift it, the whole roof comes down."

"Then we don't shift it," Émile said. "We go around."

He crawled past Félix's shoulder, pressing himself against the left wall. The chalk here was pale and streaked with dark veins, like the inside of a diseased lung. He moved three meters. Four. And there it was.

A gap in the wall. Not natural—cut, squared, framed with the same rough timbers as the rest of this ancient system. And behind it, a clear space where the air moved differently, carrying a smell that Émile knew from every field hospital he'd ever passed: gangrene, carbolic, the sweet stink of dying flesh.

He turned back and said nothing.

The side chamber was large enough to hold a company of men. It held maybe thirty. They lay in neat rows on the floor, wrapped in grey blankets—French and German blankets both, stitched together into patchwork pallets. A single lantern hung from a hook in the ceiling, burning low and steady. The men beneath it did not stir.

Émile counted ten who were clearly dead: their faces grey, their mouths slack. The others watched him with dull, exhausted eyes. One German soldier raised a hand in salute, then let it fall. A French soldier—his uniform so caked with dirt that the blue had gone brown—croaked something Émile couldn't understand.

There was no doctor here. No red cross. No orderly. Just a stack of provisions against the far wall, a bucket of water that had gone murky, and a pile of bandages that had been boiled so many times they had the texture of muslin.

And behind them, against the wall, a green door.

It was exactly as Félix had described: rusted iron, painted badly with a green that had faded to the color of old moss. The equal-armed crosses were still visible beneath the oxidation, and the hinges were massive, each one as long as Émile's forearm. No handle. No lock. Just a door set into the chalk as if someone had built it to seal something away forever.

Émile's hand went to his pocket. The Blue Madonna figurine was there, small and smooth, the broken compass inside it pressing against his thumb.

"Help me," the French soldier said. His voice was barely a whisper. "We've been here for weeks. They said they'd come back."

"Who said?"

The soldier shook his head. "The ones who brought the provisions. They said the machine was primed. They said—" He stopped, his eyes going wide. "They said you'd come. The digger. The one who carries the blue."

Émile's blood went cold. He stepped back from the soldier, and his heel caught something soft. He looked down.

It was a German field cap, but not the standard issue. This one carried a chaplain's cross on the band—a cross that matched the one Brandt wore.

Émile turned. Brandt was still in the tunnel mouth, watching him through the rubble and the dust with those pale, unreadable eyes.

"You said you were alone," Émile said. "Three days hiding in the shrine. You said you hadn't seen anyone since the bombardment."

Brandt's face didn't change. Under the chalk dust and the three days of stubble, under the exhausted hollows of his cheeks, something moved behind his eyes.

"I was alone," he said. "Eventually."

"That man in there is German. He's been alive for weeks. He's been here the whole time."

Brandt said nothing.

"And that cap—" Émile pointed. "That's a chaplain's cap. Who did it belong to?"

The silence stretched. Petit had stopped digging. Lhande and Gérard had gone still, their hands on their spades. Behind Émile, the wounded began to moan, a low chorus that seemed to rise from the earth itself.

Brandt took a breath. He let it out slowly.

"It belonged to Father Muller," he said. "He came down four months ago. The army said he deserted. The network knew better. He reached the first gate before they caught him."

"The network," Émile repeated. "The one that tried to bury us.

Brandt nodded. "They wear both uniforms. French and German. It makes no difference to them. The machine doesn't care which side digs when the ground comes down." He paused. "I was one of them. Three days ago, I decided I wasn't anymore. That's why I'm still alive."

"You're a spy," Félix said from the rubble, his voice thick with pain. "You've been leading us toward this door the whole time."

"No," Brandt said. "I've been running from the same thing you're running from. The difference is that I know what's on the other side of that door."

He pointed at the green iron.

"There's a room there. Bigger than any cathedral. And in the middle of it, a machine—old, older than anything man has built. It keeps the tunnels from collapsing. It keeps the war from reaching the deep places. And it's dying."

The wounded moaned again. The lantern guttered.

"If it dies," Brandt said softly, "everything above us comes down. Both armies. Both sides. The whole war ends in a grave the size of Flanders."

Émile looked at the door. He looked at Félix in the rubble, at the wounded men watching him with dull and desperate eyes, at Petit who crossed himself again and again.

Then he took out the Blue Madonna, held it so the lantern light caught the tiny, broken compass inside it, and pressed his palm against the green iron.

The door was warm.
