Chapter 1: Half a Broken Sword

Dusk had soaked Florence in rain and mist, and the flagstones gleamed with a cold, hard sheen. Katerina stood deep in the narrow alley, watching the gray-clad courier hurry away, a black wooden box wrapped in oilcloth rolling to a stop at her feet. Wind whipped the rain into threads that lashed her thin wool sweater, and the chill crawled up her spine. She didn't give chase. She only lowered her head, her fingertips trembling slightly.

Three years now. Ever since the day of her father's funeral, this old street called Vecchio had been her place of exile. The Grimaldi name could no longer be dug out of the city hall archives, the archaeology team's badge had long since been snapped in two, and the last letter her sister Bianca sent contained nothing but a cold money order—as if an invisible wall had risen between them.

Now the rain pattered softly. She scooped up the wooden box, turned, and retreated into that workshop of less than ten square meters. The sound of the bolt sliding home echoed heavy and hollow down the empty corridor.

Inside, the light was dim and yellow, the air thick with the metallic tang of polishing powder for old silverware. Katerina cut through the oilcloth, revealing half a broken sword. The blade was pitch black, mottled with rust, but at the notch in the edge there was a weld mark that looked deeply unnatural. She leaned close to the desk lamp, and her pupils contracted sharply.

The Latin abbreviation carved into the inner side of the blade matched, exactly, a damaged inscription sketch she had drawn in a notebook with her own hand three years ago. This was no ordinary antique. This was a fragment of history someone had deliberately erased—the riddle her father had never solved, right up to his death. Someone had reopened the old case, and they'd chosen today to do it—a day when no one so much as mentioned her mother's death anniversary.

Her fingers brushed along the spine of the blade and felt no warmth at all, as if she were gripping a cold tombstone. Outside the window, the bell tolled six—the evening prayer at San Lorenzo Church, solemn and reverent, yet it couldn't drown out the pounding of her own heart.

The doorbell rang, sharp and urgent, cutting through the dead silence. Leather shoes struck the flagstones, coming closer, carrying a kind of pressure. Katerina drew a deep breath, stashed the broken sword at the very bottom of a drawer, and turned to pull the door open. Standing there was Hans Beckendorff, the regular customer who often came by to have gilded icons repaired.

He wore a well-tailored dark gray coat, rain dripping from the brim of his hat and blurring into the water stains at the threshold. Hans didn't step in right away. He just tilted his head and glanced past her at the workshop, his eyes sharp as a blade.

"Miss Katerina," he said, his voice low, with that German roll in his throat. "I hear you've taken on some 'special' work lately?"

His gaze swept over her stain-covered apron, as if searching for some piece of evidence. Katerina lowered her eyes, her tone calm to the point of coldness. "If you mean silver restoration, sir, that's just how I make a living. Nothing special about it."

Hans edged sideways into the cramped workshop, trailing the damp smell of tobacco. He set a gilded base down on the workbench and pushed his glasses up his nose.

"This is a custom base for St. Mark's Basilica, but…" He paused, fingers tapping lightly on the tabletop. "There's something off under the oxidation layer. I'm not here to have you fix the gold, Mr. Hans."

Katerina pulled on her gloves and picked up the base, her movements practiced and mechanical. "I'm a craftswoman. Fixing gold is my job. But if you mean something else, I'm afraid that's outside my range of services."

Hans's gaze drifted to the wall behind her, where a few old blueprints her father had left were hanging—one of them with its edge deliberately burned away. His Adam's apple bobbed. He lowered his voice. "The city hall has been cracking down on illegal artifact trafficking lately. Those archives that got scrubbed clean? More dangerous than a broken sword."

Katerina's fingers paused for a second at the edge of the base, then kept working. She wiped along the seams of the gold leaf with a soft cloth, her movements gentle but firm.

"The acid etching is under the third oxidation layer," she said without looking up. "That's the signature of a strong acid bath—usually used to strip away inscriptions. It's a filthy technique, Mr. Hans. It doesn't belong to any legitimate channel, and it doesn't belong to any legal restoration process."

Hans sighed, fished a banknote from his pocket, and set it beside the base—but didn't pull his hand back.

"I once saw a man near the Uffizi holding a fragment like that. Dressed impeccably, but pale as death. Looked like he was running from someone."

Katerina stopped what she was doing and looked up, meeting Hans's eyes. There was no fear in that gaze—only a kind of cold, clinical scrutiny.

"Are you sure you saw a sword," she asked, her voice soft as a falling leaf, "and not a hallucination?"

Hans avoided her eyes and pushed the banknote a little closer. "That weld mark is ancient. It carries a clear family private-casting stamp. You won't find that kind of craftsmanship on any modern industrial assembly line."

He stood, the hem of his coat sweeping across the workbench and stirring a faint breeze.

"Contracts outlast promises, Katerina. But some contracts are written in blood. Good evening." The doorbell rang again—this time the sound of the door closing. Silence settled back over the room, broken only by the clear ticking of the wall clock. Katerina stared at the euro coin glinting under the lamp and didn't move for a long time.

Then she turned, retrieved an old magnifying glass her grandfather had left her from deep in a drawer. The frame was cast brass, badly worn at the edges, but the lens was clear as new. She opened the cabinet beneath the workbench, took out the broken half-sword, and clamped it to a wooden board.

She turned the lamp up to its brightest, brought the magnifying glass close to the repaired section of the blade. Katerina held her breath and studied the micro-structure of the weld through the convex lens. To an ordinary eye it was just a rough silver line—but to her, it was a fingerprint of time.

Tiny grains of special quartz sand were mixed into the weld, evenly distributed, giving off a distinctive matte texture. This was low-temperature cold welding—a technique only people inside the Grimaldi family knew. It required extremely low temperatures and a specific alloy ratio. One wrong move and you'd leave bubbles or cracks.

But the weld points here were flawless. A work of art, really. Which meant the person who'd repaired it wasn't just highly skilled—they had the family's internal formula. Katerina's fingers traced that thread of silver, and a chill rose in her heart. If an outsider had done it, there was no way it could be this precise. If someone in the family had done it—then the traitor was one of us.

The knock came again, light and urgent this time. Katerina opened the door. Anna Rossi stood in the rain, soaked through, strands of hair plastered to her pale cheeks. She clutched a crumpled list in her hand, her eyes full of urgency and fear.

"Rosa Rinaldi," Anna gasped, thrusting the list forward. "She's been buying up a batch of scrubbed archives at sky-high prices. The list shows the transaction went down three days ago—at an underground auction house in Brussels."

Katerina took the list and scanned the names. Her brow furrowed. Rosa Rinaldi—that elegant, respectable gallery owner who pulled the strings of the black market in artifacts, who killed people with drugs and lawyers and never left a fingerprint. Why would she set her sights on erased history?

"Why does she want these?" Katerina asked. Anna looked up, despair written across her face. "Because she knows these archives hold secrets that could bring down the entire family's reputation. She's cleaning house, Katerina. She's scrubbing memories."

Bianca pushed the door open from behind. She came in damp with the smell of rain, long hair hanging wet against her shoulders, a cup of hot milk in her hands. She didn't say anything. She just set the milk silently at the corner of the desk, steam curling up into the cold air and blurring her face. Three years of silence, broken by a single cup of something warm—and it felt so fragile.

Bianca's fingertips brushed lightly against the desktop, her gaze falling on the broken sword in the half-open drawer. Her pupils contracted. She saw the familiar private-casting stamp, and a flicker of pain crossed her face. She turned to Katerina, reached out both hands, and tried to clasp her sister's cold fingers.

"Let's do this together," Bianca said, her voice soft but steady. "We'll put these pieces back together. No matter who's standing behind it."

Katerina looked at the tears still unshed in her sister's eyes, and finally nodded.

Katerina handed the broken sword to Bianca and gestured for her to check the back of the inscription. Bianca pulled on a pair of white gloves with practiced ease and ran her fingertips along the other side of the blade. Suddenly, she stopped. There was a clear wax seal mark there, yellowed and cracked with age. Bianca looked up, a gleam of discovery in her eyes.

"There's something here," she murmured, pulling a tiny engraving knife from her pocket. Katerina held her breath as her sister carefully pried open the wax seal. The motion was delicate, like defusing a bomb. Flecks of wax scattered across the floor, revealing a small pellet wrapped in metal.

Bianca cradled it in her palm. It was an old lead bullet, its surface pitted with oxidation, a scrap of paper no thicker than a hair wrapped inside. She extracted the paper and unfolded it—and in that instant, the air in the workshop seemed to freeze solid.

Katerina leaned toward the lamp and stared at the yellowed slip. The handwriting was so familiar it made her heart clench—her father's distinctive strokes, every letter carrying the weight of his hand. There was no text on the paper. Only a date and a set of coordinates. Coordinates that pointed to the exact place her father had last been seen before he vanished.

The tears in Katerina's eyes froze to ice in an instant. She fought back the choke in her throat, her voice hoarse. "Bianca. This is Father's last message."

Her sister nodded, tears welling in her own eyes. Outside the window, the rain over Florence kept falling, soft and endless, as if it would never stop. This broken half-sword pointed not only to erased history, but to the very source of what had pushed their family into the abyss. And they had only just now gotten their hands on the key to the truth.
