Chapter 1: The Silver Dust Ledger

Guanajuato's rainy season dragged on like a festering wound. Water seeped through the cracks in the Monastery's stone walls, mixing the bitter tang of quicklime with moldy herbs. Diego Ibarra stood in the dim pharmacy, fingertips pale and stiff from weeks of soaking in distilled alcohol.

Black clouds pressed down outside the window. Then—a dull thud from the stair landing, followed by the scrape of cloth dragging across stone and a ragged, heavy breath. Diego's gut twisted. He was across the room before he'd decided to move.

Rosario Vargas was curled on the floor—the old miner who'd spent half his life in the San Juan Silver Mine—dark blood foaming at the corner of his mouth. Diego dropped to his knees, checked the man's vitals: pupils pinwheeling shut, breathing fast and shallow. "Mr. Vargas, it's Diego. Stay still. Keep breathing." His voice was cold—nearly ruthless—the kind of calm you only get from triaging casualties in a field hospital.

Rosario's clouded eyes rolled to focus. He clamped down on Diego's wrist with a grip that shouldn't have been possible in a man this far gone. "Don't... don't call the police... they... haven't left yet..."

Diego didn't have time to figure out who "they" were. Training took over—stop the bleed, fight the shock. He tore open his sleeve, revealing the hemostats and suture thread he kept on hand at all times, and clamped the torn soft tissue beside the old man's trachea with a precision that would have made a surgeon wince. Clean. Fast. No secondary damage.

He barked orders at Carmen Estrada, the nurse who'd rushed in to back him up: epinephrine, normal saline. At twenty-eight, Carmen carried a hardness in her eyes that belonged to someone half her age. She disappeared down the dark corridor without a word.

Once the IV line was in, Rosario's color eased a fraction, but his consciousness kept fraying at the edges. Diego watched the blood pressure numbers, tracked the tremor in the old man's fingers. Just as he was about to call it done, Rosario surged up and seized Diego by the collar, gaunt fingers locking around his throat hard enough to make Diego's brow clench.

"Listen to me... Diego." The old man's voice was a thread, barely there, but the words were razor-sharp. "That Silver Plate... it's in your pocket."

Diego froze. Instinct sent his hand to his inner pocket—and yes, cold metal was sitting there, slipped to him by Rosario before the old man lost consciousness. He'd figured it was a keepsake, maybe an old coin. But now, under the dying man's fading gaze, The Silver Plate felt like it weighed more than lead. More than guilt.

"What is this?" Diego murmured, thumb tracing the rough, hand-cut edge.

"Coordinates..." Rosario gasped, each breath looking like it cost him something. "1891... The False Death Ledger... Raphael Fuentes... the men he killed... they're buried there... Don't trust the accountant... Guadalupe Aguilar... he's lying..."

The last warning dropped out of him like a stone into still water. Rosario went limp, his fingertip giving one final tap against Diego's chest. The monitor line stretched flat. A harsh, unblinking straight line. Diego didn't touch it. Some debts, he knew, someone had to collect.

Carmen stood in the doorway, having watched the whole thing. She stepped closer, voice low. "He's gone. Fast, too. Like an old horse that finally set the load down."

Diego got to his feet. The Silver Plate in his palm threw off a cold, greenish glint under the gas lamp. He turned to face Carmen.
