My Fiancée Claimed My Sister Ran Away Years Ago—Then I Found Her Bracelet Beside a Hidden Trapdoor in My Own Mansion.

The crystal chandeliers of the Bellandi estate cast a warm amber glow over three hundred guests, but Victor Bellandi felt none of the warmth. He stood broad-shouldered in his custom midnight-black tuxedo, towering over the politicians and capos laughing near the ballroom fountain. His polished shoes made no sound as he stepped away from the crowd, his rugged face carved in stone.

Something was wrong.

He had heard it twice now. A dull, rhythmic knocking echoing faintly through the mansion’s eastern wing.

Victor walked down the quiet, wood-paneled hallway toward the private library. The noise grew sharper. It wasn't plumbing. It was deliberate. Three taps, a pause, then two more.

He reached for the heavy mahogany library doors, but a sudden rustle of silk cut him off.

Celeste appeared in the doorway. She looked immaculate in an extravagant silver evening gown that shimmered under the sconces, diamonds glittering around her pale neck. She forced a bright, practiced smile and placed a manicured hand flat against Victor’s chest.

"Aren’t you supposed to be in the reception hall?" Celeste asked, her tone smooth as honey.

Victor looked down at her. His cold eyes didn't blink. "What’s under the floor, Celeste?"

"Don't be ridiculous, darling. The wine cellar compressors are old. Come, the Senator is asking for you."

Victor didn’t move. His gaze dropped past her silver hemline to the antique oak planks. Trapped between two floorboards near the base of the massive bookshelf was a thin silver chain with a teardrop sapphire.

Victor froze. His jaw tightened until the muscles bunched like iron.

He had bought that bracelet in Florence eighteen years ago for his younger sister Adriana's eighteenth birthday. The sister who had vanished three years ago without a trace.

Victor pushed past Celeste with one brutal sweep of his arm. He dropped to one knee, gripped the edge of the disguised floorboard, and tore it upward with raw, furious strength. The hidden hydraulic pins snapped with a loud crack.

Beneath the floor lay a narrow, lighted concrete chamber.

Curled on a thin cot was a woman in a faded dark dress and worn flats. Her skin was pale and her dark hair was matted, but the high Bellandi cheekbones were unmistakable.

She looked up, squinting through the sudden light, and weakly reached toward him.

"Victor…" Adriana whispered, her voice trembling. "She told everyone I ran away."

Victor reached down and hoisted his sister out of the hole in one fluid, protective motion, pulling her against his chest. He set her gently onto the leather armchair, turned, and stepped toward Celeste.

Victor didn't raise his voice. He didn't ask a question. He swung his heavy hand across Celeste’s face.

The slap cracked like a gunshot. Celeste staggered backward, lost her balance, and crashed violently into the nine-foot mahogany bookcase. The structure toppled sideways, hitting the floor with a deafening crash as hundreds of leather-bound books scattered across the Persian rug.

Dust rose into the air. Celeste lay amidst the ruined books, her fair cheek already swelling with a deep purple bruise.

Slowly, without a single tear, she pushed herself up from the floor. Her silver gown was torn at the shoulder, but her icy blue eyes burned with terrifying confidence.

"Go ahead and set her free," Celeste said in a low, threatening voice, wiping blood from the corner of her lip. "And then you’ll understand why your father buried the truth."

Adriana staggered forward and gripped Victor’s tuxedo sleeve with white knuckles.

"Victor…" Adriana said softly, her breath catching in her throat. "He knew the truth about our biological father."

Victor froze in shock.
