Read Chapter 7: The Promise

The dressing on Félix’s shoulder had gone stiff overnight, and when Émile peeled it back in the grey of false dawn, the wound had turned the colour of spoiled meat. Streaks of red climbed toward his collarbone, angry and branching like the fissures in the tunnel walls.

“It’s nothing,” Félix said, but his teeth were chattering and his skin had the waxy sheen of a man who’d been left out in rain too long.

Émile pressed the back of his hand to Félix’s forehead. Hot. Too hot. “You’re going to the field hospital.”

“The hell I am. They’ll take my arm.”

“They’ll take your life if you stay.” Émile tore a clean strip from his own shirt and rewrapped the wound, tighter this time. Félix gasped but didn’t cry out. He never cried out. Not since they were boys and Félix had fallen from the quarry ledge, breaking his wrist and saying nothing until their mother noticed the swelling at supper. The Marchands bore pain in silence. It was a family trait that had killed his brother Antoine just as surely as any German bullet—walking into an avalanche rather than turning back, because turning back meant admitting the mountain had beaten him.

Émile pushed the thought away. He needed to focus on the living.

“Listen to me,” Félix said, gripping Émile’s wrist with his good hand. The strength in it surprised him. Fever gave men strange reserves. “Whatever you’re planning—the tunnel, the Germans, all of it—I don’t want to know. But when you find it, the way through, promise me you’ll take it.”

“Take what?”

“The pathway home.” Félix’s eyes were bright and glassy, fixed on something beyond the ruined wall of the château cellar. “I saw it. In the tapping. It answers because it knows your name, Émile. The old stone remembers the Marchands. You promised Antoine you’d find him. Find the pathway instead, and you’ll find them both.”

“You’re delirious.”

“Promise me.”

Émile looked at his brother’s hand on his wrist—the same broad palm, the same coal-dusted knuckles that their father had worn smooth as river stones. He couldn’t refuse a Marchand deathbed request, even one born of fever.

“I promise.”

Félix smiled, and for a moment he looked twenty years younger, like the boy who’d once believed the quarry tunnels led to the centre of the earth and that dragons slept below. Then his eyes rolled back and his grip went slack.

Émile carried him up the cellar stairs. Claude met him at the top, face tight with worry.

“I’ll take him,” Claude said, reaching for Félix’s shoulders. “You’ve got mud in your boots and secrets in your coat. One of us has to look like a soldier.”

It was true. Émile’s uniform was a disgrace—torn at the knee, caked with chalk dust from the tunnel, blood from a dozen small cuts he hadn’t bothered to clean. He looked like a deserter, or worse, a man who’d been digging where he shouldn’t.

“The dressing needs changing every four hours,” Émile said. “If it blackens, cut it off above the elbow. Don’t wait for a surgeon who’s got sixty other men to see first.”

Claude nodded once, the gesture of a man who understood. He hoisted Félix onto his back with a grunt and carried him out into the morning mist. Émile watched them go until the fog swallowed their shapes, then turned to find Corporal Bryce standing in the shadow of the doorway, arms crossed, watching him with unsettling stillness.

“Your brother?” Bryce asked.

“Yes.”

“The one from the letter.”

Émile stiffened. He hadn’t told Bryce about the letter—about his mother’s illness, about Antoine’s silence since Verdun. Somehow, the Englishman knew anyway. “You have good ears.”

“I have good sources.” Bryce stepped inside, closing the warped door behind him. He moved with the easy confidence of a man who owned whatever ground he stood on. “I also have good eyes. I saw the carvings in the cellar. The spiral. The inscription. That’s Templar work, that is. Ninth century, if I’m any judge.”

“You’re a tunneler. What do you know of Templars?”

Bryce smiled, and something in his expression shifted. The rough edges of the NCO fell away, revealing a sharper cut beneath. “I’m not a tunneler, Marchand. Not exactly.”

Émile’s hand drifted toward the revolver at his hip. “Start talking, or I start shooting.”

“Easy now.” Bryce raised both palms. “You’re right to be wary. Deception is the currency of this war, and I’ve spent a good deal of it. But I think we have common ground, you and I.”

“What ground is that?”

“The ground beneath our feet.” Bryce moved to the table where Émile had spread his map, the one marked with the abbey and the old mines. He ran a finger along the pencilled notations. “I’m a captain in the Royal Engineers. Tunnelling Corps, Seconded to Special Duties.”

“Special duties.”

“I was sent here to investigate rumours. Rumours of a vast cave system beneath both lines. Rumours the Germans have found it and are using it to move troops unseen, perhaps to undermine our positions on a scale we can’t match with conventional galleries.” Bryce’s eyes met Émile’s. “Six months ago, our intelligence intercepted a German dispatch referencing a ‘subterranean highway’ running from Lille to the sea. We laughed at it. Called it propaganda. Then three of our best tunneling officers vanished—not killed, not captured, just gone—while surveying a collapsed shaft near Ploegsteert. Now I’m here. And I find spirals and Templar inscriptions in a château cellar, with a stairway leading down into the dark.”

“You think the Germans are the other side of that darkness.”

“I know they are. I’ve heard them. Same as you.” Bryce straightened. “But here’s what I don’t know, Marchand: what you’re planning to do about it. You were ordered to place six hundred kilos of ammonal under Hill 60. You didn’t. You’ve been skulking about unauthorized tunnels, talking to deserters, and lying to your lieutenant. Now your section is cut off behind German lines, your brother’s been taken to hospital, and you’re standing in a cellar that might as well have a sign over the door saying ‘COME DOWN HERE’ in six-foot letters.”

Émile said nothing. He’d learned long ago that silence was a miner’s best tool. It let the earth speak first.

Bryce continued, his voice dropping lower. “I’m not here to arrest you. I don’t care about your orders from Lieutenant Moreau, and I don’t care about your deserters or your midnight expeditions. I care about one thing: whether the Germans can move a division under our lines without us knowing. If they can, this war is lost by Easter. If we can beat them to it, if we can find that highway and hold it, we could win the war in a week. So I’m asking you, man to man, soldier to soldier: what did you find down there?”

Émile considered his options. He could lie again, but Bryce had already seen through three of his deceptions. He could refuse, but then Bryce would become an obstacle, and Émile had too many obstacles already. Or he could trust the Englishman—a man who’d come down a dark shaft with nothing but a torch and a nerve of steel, who’d seen the same symbols and heard the same answering taps.

In the end, it wasn’t any of those calculations that decided him. It was Félix’s voice in his head, fever-bright and desperate: *Find the pathway home.*

“The ammonal,” Émile said. “I’m not going to detonate it. The ground under Hill 60 is unstable—it’s honeycombed with galleries older than the war, older than the Romans, maybe older than anything we have names for. If we blow that charge, we don’t just collapse a hill. We collapse the access to everything below. Both sides’ access.”

Bryce’s eyebrows climbed. “You want to use it. Use the tunnels.”

“I want to prove there’s a corridor that runs under both lines, clear enough for men to move through—a way to flank the Germans from beneath.” Émile tapped the map. “There’s an abbey five kilometres west of here, marked on this map with a symbol that matches the carvings in the cellar. There’s a shaft network connecting it to the château—I’m certain of it. If I can reach the abbey, I can find the main gallery. And if I can find the main gallery, I can map a route that bypasses the German trenches entirely.”

“That’s a big if, Marchand.”

“That’s why I need you.” Émile met Bryce’s eyes. “You’re an officer. You have authority. You can requisition supplies, fresh men, explosives, timbers. You can get me the resources I need to probe the galleries before Moreau blows the whole thing sky-high.”

Bryce was quiet for a long moment. Outside, the distant crump of artillery rolled across the fields. The war was continuing without them, indifferent to their plans.

“If I do this,” Bryce said slowly, “I need something in return.”

“Name it.”

“When we find that corridor—and we will find it—you take me with you. All the way down. I didn’t come across the Channel to watch from the surface.” He extended his hand. “Deal?”

Émile looked at the offered hand. Trusting an English officer. Trusting a man who lied about his rank, his mission, his very name. It went against every instinct his father had drilled into him about keeping his own counsel.

But Félix had asked for a promise. And Marchands kept their word.

Émile took Bryce’s hand and shook it.
