Read Chapter 26: The Fallen Tower

The château's grand salon had become a war zone.

Marcus pressed his back against a marble pillar, the crack of gunfire splitting the air above his head. Plaster dust rained down like snow. Across the room, Sophie crouched behind an overturned settee, her expression sharp and focused as she sighted down the barrel of a pistol she'd pulled from God knows where.

"Two on the balcony," she shouted. "One more circling from the garden."

Petrova moved like smoke along the eastern wall, her silhouette barely registering before she returned fire. A body crumpled somewhere beyond the broken French doors. The stench of cordite mixed with the sweat and old leather of the room.

"Who are these people?" Marcus yelled, pressing his palms over his ears as another volley hammered through the windows.

"The Order's cleaning crew," Petrova said, reloading with mechanical efficiency. "They don't negotiate. They sterilize."

The clock above the fireplace — a towering Louis XIV piece, all gilded bronze and mother-of-pearl — took a bullet to its face. Glass shattered, spraying across the marble. The clock's hands quivered, then stopped. And then, with a groan that sounded almost human, the entire casing shifted.

Not a clock. A door.

The bronze face swung inward on hidden hinges, revealing a narrow spiral staircase descending into darkness. Cold air breathed up from below, carrying the faint mineral scent of water and stone.

Sophie was already moving toward it. "Tunnel?"

"Cellar access, probably." Petrova fired three rounds toward the balcony, then ducked back behind a collapsed bookshelf. "The lake. There's a water gate."

Marcus ran for the stairs, gunfire biting at the marble behind him. He was halfway through the opening when something slammed into his shoulder — not a bullet, but the edge of the grandfather clock's broken casing, knocked loose by a ricochet. He stumbled, caught his balance on the cold iron rail, and descended into darkness.

The stairs were old, worn smooth by centuries of feet. The air grew colder with every step. Above them, the gunfire continued, muffled now by layers of stone. Sophie came down fast behind him, her boots ringing on the metal treads. Petrova followed, pulling the clock door shut. The latch clicked into place — old machinery, oiled and maintained. It would hold for minutes, not more.

A single overhead bulb cast yellow light across a stone corridor that stretched toward the lake. Wine racks lined the walls, their bottles covered in dust and cobwebs. At the far end, a heavy oak door with iron bands. Markus could hear water lapping against stone on the other side.

They'd almost reached it when Marcus heard the sound. A whisper of movement above, too quiet to be debris. He turned—

The sniper had found the maintenance hatch.

The shot came through a ventilation grate near the ceiling. A crack like lightning splitting a tree, and Petrova was between Marcus and the bullet in the same instant she registered the sound. Her body jolted, back arching against an impact that snapped her forward and sent her sprawling across the stone floor.

No. The word didn't form in Marcus's mouth before another round punched through the grate, hitting the oak door's iron latch and fusing it shut.

Sophie was up the stairs before Marcus could think, her pistol barking twice through the grate. A cry from above — flesh, not metal. The grate went silent.

Silence fell like a weight.

Marcus crouched over Petrova. Her dark eyes were already glassing, blood pooling in a dark ribbon beneath her ribs. She grasped his wrist. Her grip was surprisingly strong, though her breath came in shallow, labored bursts.

"Marcus." Her voice was thin, almost a whisper. "The clock."

"What?"

"The clock hands." She swallowed, grimacing as the movement pulled at her wound. "Bronze. They're keys. Brass keys, hidden in the hands. The third key — it's not a coin, not a signature. It's a name." Her fingers tightened. "The account needs blood and bone. My brother bought it with his life. Your parents paid with their silence."

"Petrova, we need to get you—"

"Listen." The word was a command, even now. "Jean-Baptiste Arnaud. He's not for me. He's for the True Guardians. They think they're protecting something. A secret. But the secret is a wound. They want to keep it open."

Her hand slipped from his wrist. She reached into her jacket, trembling fingers producing a folded piece of paper, damp with blood. "Tom left this. He was your friend first. It's the location — where the final node lives."

Marcus took the paper. The dark ink was smudged but legible, Tom's cramped handwriting unmistakable. A single line: *The church of bones cries when the earth remembers.*

"The Catacombs," Sophie said, crouching beside him. Her face was pale, but her voice was steady. "Paris. The ossuary walls."

Petrova's eyes found Marcus's. "Your parents. They could have surrendered you. The Order would have taken you, raised you, used you as collateral until your bloodline was spent. They refused. Chose silence. Chose to make themselves invisible." A weak, bloody smile touched her lips. "I was never given that choice."

"Petrova—"

"You said I was a monster." Her voice rattled. "Maybe I was. But I'm a monster who wanted to burn the ledger. Not for gold. For the dead. All of the dead."

Marcus pressed his hand against her wound, but there was too much blood. Her heartbeat slowed under his palm, fluttering like a bird's wing against the glass.

"Berlin," she whispered. "My brother. He was the one who stole the master key first. They killed him for it. I finished what he started. Tell them, Marcus. Tell them what they did. Tell them it wasn't about money. Tell them—"

Her eyes found the ceiling, saw something far away from this cellar. Her hand fell.

The silence stretched. Somewhere above, orders being shouted. The latch on the clock door strained under a boot.

Marcus straightened, still holding the paper. His chest felt tight and empty all at once. He'd known her for less than a month — an enemy, a rival, a thief. But she'd stood between him and that round. She'd traded her breath for his.

Sophie put a hand on his shoulder. "We have to go. The water gate."

Marcus looked at the oak door. The snipers had fused the latch, but the wood was old, and the frame had rotted through in decades of lake moisture. He pulled his knife and worked it into the gap between the door and the jamb. The wood gave way with a groan, splintering inward.

Beyond it, the lake lapped at a narrow stone landing. A small motor skiff bobbed against a corroded cleat, half-hidden beneath a canvas tarp.

Marcus turned back. Petrova lay still on the stone floor, her eyes closed, one hand still outstretched toward him. He knelt and gently closed her eyelids with two fingers. His hand came away red.

"Who was she to you?" Sophie asked quietly.

"Complicated." He slipped the bloodied paper into his inner jacket pocket, next to the wolf coin. "Her brother was a thief who stole from the wrong ledger. She spent her whole life trying to undo it."

"And she saved you."

"Yes."

Sophie didn't say anything. Instead, she stepped past him to the skiff and began loosening the tarpaulin. Her movements were quick, efficient — no hesitation, no hand-wringing. In the château above, their pursuers would soon batter through the clock door. Below, the lake offered a way out.

Marcus stood over Petrova's body for a long moment. Visions of Zurich, the server farm, his parents' name in the ledger — all of it collided in his head. She'd known about them. She'd known about his parents buying his freedom with their own silence.

He pulled the wolf coin from his pocket and looked at it. Bronze, worn smooth from centuries of handling. On one side, a wolf's head. On the other, an inscription in Latin. *Per crucem ad aeternam.* Through the cross, to eternity.

The paper in his pocket was heavy. Tom's handwriting. *The church of bones.* The Catacombs. Whatever waited there had been waiting for generations.

He trusted Sophie now. Fully. She'd seen him laid bare, seen his debt and his anger, and she hadn't flinched. She'd stayed. She'd fought.

"Sophie." Her name came out rougher than he intended.

She looked up from the skiff, eyes dark in the dim light. "Yes?"

"Thank you." He said it simply, without armor. "For staying."

A flicker of surprise crossed her features, then something softer. "You'd do the same."

"I would." He meant it.

She held his gaze for a moment longer, then nodded once, briskly, and unhooked the boat's painter line. Without looking back at him, she stepped into the skiff and offered him his hand.

"Paris, then? The Catacombs?"

He took her hand, stepping into the boat. The hull dipped with his weight. Behind them, the château groaned as the clock door shuddered.

"Paris." Marcus stowed the coin and the paper. "But first," he said, pulling out his dead phone, "we need to make a call."

"What for?"

"Petrova said Jean-Baptiste Arnaud is the True Guardians' designated survivor. If they're hiding in the catacombs, and if they think they're protecting a secret that's actually a wound, then they're as dangerous as the Order. We're going to need what they know. And they're going to need what I know."

Sophie's eyebrow arched in a question, but she didn't ask it. She simply started the skiff's engine, pointed the bow toward the far shore, and let the little boat carry them out of the shadows.

Paris was still two days away. But the ledger was still running. And now, Marcus knew where Tom had hidden the final key.

The catacombs would have their reckoning.
