Read Chapter 20: The Voice

The tapping came from everywhere and nowhere. Émile pressed his ear to the damp chalk and felt the vibrations travel through his jaw like a second heartbeat. The rhythm was precise—deliberate. Not the random settling of earth or the scrabble of rats. This was code.

He lay in the drainage pipe that had carried him down from the French lines, his breath shallow, fingers splayed against the wall. The message repeated twice, then paused, then came again with a variation. He recognized the pattern from his training at the 6th Engineer Regiment—tapping stations operated by the British across the line. But this wasn't British. The spacing was off. The intervals too clean.

A voice drifted through the dark, thin and reedy, carried along the pipe's curve like a current of air. It spoke in a whisper of French, mangled by distance and stone: “…find me… the door is not the door… find me before the candle dies…”

Émile’s pulse hammered. He crawled forward, elbows scraping against years of silt and rust. The pipe narrowed, and for a moment his shoulders caught, panic flaring hot in his chest, before he twisted and forced himself through. The pipe opened into a broader passage, one he didn’t recognize—a natural fissure that had been widened by hand, the marks of a pick still fresh in the chalk.

The tapping resumed, closer now. He followed it, counting his steps as his father had taught him in the mines. Forty paces. Fifty. The passage curved sharply, and there, ahead, a faint light glowed—not the yellow of a lamp or the blue of the Madonna’s shrine, but white and steady, like a candle burning in still air.

The tomb was small, no larger than a confessional. Shelves had been cut into the walls, and upon them sat candles, most burned down to stubs. In the center, propped against the far wall, sat a man in a French infantry uniform. His left leg was wrapped in blood-soaked rags, and his face was the color of old paper. A candle burned beside him, nearly spent.

“You came,” the man said, without surprise. “I wasn’t sure you would. The others don’t hear the tapping. Only the ones already underground.”

Émile knelt, keeping his distance. “Who are you?”

“A bad soldier and a worse spy.” The man coughed, blood flecking his lips. “Name’s Lucien. I was with the 5th Chasseurs. Then I wasn’t. Then I was with the other side. Then I wasn’t that, either.”

“You’re a double agent.”

Lucien smiled weakly. “Double implies two masters. I’ve served four.” He shifted, wincing, and gestured to a satchel at his feet. “The Brotherhood doesn’t care about flags. They care about what’s underneath them. The tunnels, the shrines, the chambers that were old before the Gauls. They’ve been down here for centuries, watching. Keeping. I was their eyes on the surface.”

“The Brotherhood,” Émile repeated. The word sat strange in his mouth. “Brandt mentioned them. In his journal.”

“Brandt.” Lucien’s eyes flickered with something like recognition. “The chaplain. Good man. Wrong side, right cause. He knows what the generals don’t—that this war is being fought on the skin of something far older. And that there are those who would crack that skin open to get what’s below.”

The candle guttered. Lucien’s hand shot out, steadying it. “The green door,” he said. “You’re looking for it.”

“You know where it is.”

“I know where it isn’t.” Lucien laughed, then coughed again, harder this time. “It’s not under Hill 60, no matter what the priest told your brother. It’s not under the château, though you’ll find a guard there for your trouble. The door moves, sapper. It shifts with the water table, with the tides, with the weight of the dead above it.”

Émile leaned closer. “Then how do I find it?”

Lucien’s eyes met his, and there was something ancient in them, something that had seen too much dark. “You don’t. It finds you. But if you want to shorten the wait…” He reached into his satchel with trembling fingers and withdrew a folded piece of oilcloth. “The defense chamber. A cache hidden by the French engineers in ’15, sealed when the front moved. Coordinates are marked. Provisions, tools, a map of the secondary galleries. It will keep you alive long enough to be found.”

Émile took the oilcloth. It was heavy, coated in wax, and bore a faded stamp of the 3rd Engineer Regiment. “Why are you giving me this?”

“Because the Brotherhood wants the door protected,” Lucien said, his voice dropping to a whisper. “And the one thing that threatens it more than the Germans is the ambition of a French colonel with too much ammonal and not enough conscience.”

Émile’s blood went cold. “Moreau.”

“So you know his name. Good. Then you know what he plans.” Lucien’s hand clamped around Émile’s wrist, surprisingly strong for a dying man. “The mother lode, sapper. It’s not under the German lines. It’s under both. Under the ridge, under the chapel, under the field hospital where your brother was last seen. If Moreau lights it, he doesn’t just take the hill. He collapses a hundred kilometers of tunnels and buries the door forever. The Brotherhood won’t allow that. Neither should you.”

“My brother,” Émile said, his voice cracking. “Antoine. Is he with the priest? Is he alive?”

Lucien opened his mouth to answer, but his body convulsed instead. The cough that followed was wet and brutal, blood spattering his chest in dark blossoms. He sagged against the wall, his grip on Émile’s wrist loosening.

“Your brother,” he rasped, “made a choice. The same choice you’re going to have to make. The surface… or the deep.”

“What does that mean?”

Lucien’s eyes drifted past Émile, to somewhere beyond the candlelight. “The tapping,” he said, almost dreamily. “It’s not them. It’s not the British. It’s the others. The ones who didn’t choose the surface. They’ve been tapping for eight hundred years. And now they’ve found a new voice to answer them.”

His body went slack. The candle beside him flickered once, twice, and died.

Émile sat in the sudden dark, the oilcloth clutched against his chest, the man’s final words echoing in the narrow chamber. He reached out, his hand hesitating over Lucien’s tunic. A soldier’s instincts—check for papers, for orders, for anything that might explain who he was dealing with. His fingers brushed something hard in the breast pocket. He drew it out, felt its weight.

Iron. Simple. Heavy. A key with an ornate bow, too old for the locks of any trench or dugout he’d ever seen.

The tapping resumed, faint but unmistakable, coming from a new direction—from beneath, rising through the floor of the tomb. It pulsed in a rhythm he almost understood, as if trying to spell out a word in the dust of centuries.

His name. The voice from the deep, closer now, patient, no longer calling across the dark but standing just on the other side of it.

Émile pressed the key into his palm, feeling its cold solidity. Lucien had given him a map. A cache. A name for his enemy. But the key—the key belonged to another purpose entirely. And the voice in the floor was certain he would use it.

He rose, tucking the oilcloth into his tunic, slipping the key onto the cord around his neck beside the scrap of Antoine’s letter. He did not look back at Lucien. There was nothing left to learn from the dead.

But as he stepped into the passage, the tapping changed. It became faster. More insistent. And for the first time, Émile realized it wasn’t calling him forward.

It was warning him of what he would find ahead.
