Read Chapter 16: The Cost of Knowledge

The cave mouth exhaled cold air thick with the mineral smell of wet stone. Étienne stood at its threshold, the diary still open in his hands, the words of his brother’s final entry burning behind his eyes. Behind him, Claire’s breathing was measured, deliberate, the way she steadied herself before a surgery.

“We need to move,” she said quietly. “That blood trail won’t stay fresh forever.”

He closed the diary. The leather was worn soft at the corners, the spine cracked from decades of handling. He tucked it inside his coat and turned to face her. In the pale light leaking through the fog, her face was unreadable, a mask of professional composure that he knew by now cost her something real.

“There’s something I have to tell you.”

“About Gaspard.” It wasn’t a question. She had read the diary over his shoulder, had watched his face as the truth settled into him like lead shot.

“About more than that. There’s a chance I’ve been lying to all of you. Not about what I knew. About what I suspected.” He forced himself to hold her gaze. “I need to tell the others. Before we go any deeper.”

Claire’s jaw tightened. She looked past him, into the dark of the cave, then back. “You think they’ll want to keep following you after this?”

“I don’t know what they’ll want. But they deserve the choice.”

She nodded once, sharp. “Then we go back.”

The walk down from the ridge took forty minutes through thinning fog. By the time they reached the truck, the afternoon light had gone amber and thin. Giancarlo stood by the hood with a field dressing pressed to his forearm, the bandage stained a faint rust color. François sat on the tailgate, rosary beads clicking between his fingers.

Giancarlo saw Étienne’s face before anyone spoke. He straightened. “What happened?”

“We need to talk.” Étienne dropped his pack by the wheel well and leaned against the truck’s flank. The metal was warm from the engine, and it grounded him, kept his hands from shaking.

Claire stood apart, arms crossed, giving him the stage.

Étienne told them. Everything—the diary, the surgical recordings in Gaspard’s hand, the transformation. That Hartmann wasn’t just summoning a beast. That she had found a way to make one. That the thing in the mountain wore his brother’s bones.

When he finished, silence pooled in the clearing. A bird called somewhere high in the pines. Giancarlo’s face had gone still in that particular way men learn when they’ve held composure through worse news than this.

“You knew,” Giancarlo said. It wasn’t an accusation so much as a statement, flat and tired.

Étienne shook his head. “I suspected. On some level. I’ve been hunting this thing for seventeen years, and every time I got close, the pattern felt… personal. The way it moved through terrain. The way it chose its victims.” He rubbed his jaw. “But I didn’t know. Not until the diary.”

“You should have told us.” Giancarlo’s voice rose, a crack in the calm. “We walked into a mountain with you and you didn’t think to mention the thing we were hunting could be your brother?”

“I didn’t know it was him,” Étienne repeated, quieter. “And if I had told you I suspected, would you have come? Would you have walked into that pass with a man who thought his own brother might be the beast?”

Giancarlo’s mouth worked. He looked away, toward the treeline, his wounded arm flexing. Étienne could see the calculation happening behind his eyes—the inventory of risks taken, injuries suffered, all predicated on a lie Étienne had told by omission.

Claire stepped forward. “There’s more.”

Étienne stiffened.

She turned to face him fully. In the amber light, her eyes were pale and unflinching. “You didn’t just suspect, did you? That first night in Martigny, when we shared a room. You took your shirt off to wash. I saw your forearm.”

Étienne’s stomach dropped. He’d forgotten. Or he’d hoped she hadn’t noticed. The scars ran from his wrist to his elbow, a lattice of pale grooves where teeth had raked down to the muscle—too regular to be anything but bites. Human bites.

“I saw them,” she said. “Before I knew what they were. I thought maybe an animal attack. A dog, a wolf. But the spacing was wrong.” She paused. “That was Gaspard, wasn’t it?”

The word hung in the air. Étienne felt the weight of it press down on his shoulders. The scar tissue ached, phantom memory, teeth grinding through skin and tendon.

“We were young,” he said slowly. “Fourteen and eleven. He’d been having dreams for weeks—nightmares, he said. Animals screaming in the snow. I thought it was just adolescence. But then the attacks started. Livestock first, stripped clean. Then two hikers, a couple from Geneva, found in a ravine above the tree line. The village blamed wolves. My father knew better.” Étienne’s voice dropped. “He was Warden. He’d seen the signs before.”

“What signs?” François asked quietly.

Étienne shook his head. “A change in the boy. The way he looked at his own hands. The way he’d go silent when the moon was low and full. I didn’t want to see it. He was my brother. He taught me to fish. He cried at our mother’s funeral.” His throat tightened. “Then one night, he came to my room. He was shaking, fever-hot. He said something was inside him. Said it whispered to him in our father’s voice.” He paused. “He asked me to kill him.”

The forest had gone silent. Even the bird had stopped.

“I couldn’t,” Étienne said. “He was my brother. I got him out of the house instead, into the mountains. I thought if I could get him to the high pass, to the old shrine, maybe the monks there could help. But we never made it. Something in him broke mid-climb. He turned on me.” He rolled up his left sleeve, showing the scars for the first time. “He bit me. Not to kill. To mark. The way an animal marks its territory. Then he ran, and the mountain took him. I searched for three days. The village searched for a week. We found nothing. Not a trace.” He pulled the sleeve down. “I’ve carried the guilt ever since. I should have listened to him. I should have helped him. Instead I let him become… this.”

Giancarlo’s posture had softened, but his eyes were still hard. “You let us go into that ravine without telling us any of this.”

“Because it changes nothing,” Étienne said. “The danger is the same. The mission is the same. I’m the one who has to carry the weight of what he’s become. Not you.”

“But it does change things,” Claire said quietly. “It changes how we plan.”

François stepped forward. He had been silent through all of it, rosary still moving, but now his eyes were bright. “There is something I haven’t shared with the group. Something from the texts at the archive.”

Étienne looked at him. “What kind of something?”

“About the Warden. About how the bond is broken.” François moved closer, his voice taking on a careful cadence. “In the oldest of the Aymon texts, the ones Hartmann referenced, there’s a passage about the ‘hunter’s bond.’ The creature—the beast—it’s bound by blood to the one who made it. To sever that bond, the maker must be unmade by a pair of hunters.”

Claire frowned. “A pair?”

“One human and one beast,” François said, “or two humans. But they must hunt together. Strike together. The killing blow must be shared. Ancient logic—balanced. It is the mountain’s way of correcting an imbalance. One hunter alone cannot do it. The beast will always overcome a single will. But two hearts beating in unison can break the spell.”

Silence. Étienne could hear the creek below the road, the distant rush of water over stone.

Giancarlo was the one to speak. “So we need two people to kill the thing together?”

“Two of a kind,” François said. “Two hunters. Two men who share a bond.”

Étienne’s gaze drifted back to the canyon beyond the ridge, where the cave waited, where his brother waited. Two hunters. He thought of the diary’s last entry—Gaspard’s handwriting, curling and strange at the edges, the letters beginning to slant like claws. *You will come*, it said. *You will come and you will try to end this. But you cannot do it alone. You never could.* Étienne had thought it a taunt. Now, in the context of François’s words, it felt more like an invitation. He had been bait to draw Étienne close. But if the bond required a pair…

Claire was watching him. “You’re thinking about it,” she said. “About who would go with you.”

“There’s no one else it could be,” he said. “No one else who’s walked what I’ve walked.”

“Then you’re thinking about killing your brother with someone at your side,” she said, quieter. “That’s heavy company to keep.”

The wind shifted, and for a moment Étienne smelled snow high on the wind. He looked at the two keys in his coat pocket—one his father’s, one the dead monk’s—and felt the weight of every choice that had carried him to this pass.

“I’ll sort it out,” he said. “But not tonight. Tonight we make camp somewhere defensible. We tend to Giancarlo’s arm. And we plan.”

He walked past them to the truck’s cab, pulled open the door, and sat. The engine was cold. He pressed his forehead to the steering wheel and breathed. Above him, the last of the light bled from the sky, and the mountain waited, patient and enormous, holding his brother in its dark.
