The De Santis residence was not a house; it was a fortress dressed in Renaissance marble. Lucía sat in a high-backed leather chair inside Matteo’s private study, surrounded by dark mahogany shelves and the suffocating scent of expensive cigars and old paper.
The heat in the room was oppressive, or perhaps it was just the adrenaline burning through her veins.
Matteo sat behind a massive desk. He slid a single sheet of heavy, cream-colored paper across the polished wood.
"Read it," he commanded.
Lucía pulled the paper toward her. Her eyes scanned the text with the rapid, mechanical precision of an auditor.
The terms were clear. Cold. Logical. Matteo would guarantee Alba’s immediate relocation and absolute immunity. In exchange, Lucía would surrender the decoded ledger. She would reside within the palazzo walls under Matteo’s direct protection.
Then she reached the final paragraph. She stopped reading. Her grip on the edge of the desk tightened until her knuckles turned white.
"A public engagement," she said, her voice flat, devoid of the panic clawing at her throat. She looked up at him. "You want me to pose as your fiancée."
"I want you to be untouchable," Matteo corrected, his gaze unwavering. "If you are merely an informant, Carlo will have you quietly poisoned in the kitchens. If you are a house guest, you are a hostage. But if you are the future of the De Santis family, harming you is an act of treason."
"It makes me a target," she snapped, the polite veneer cracking. "It paints a bullseye on my back for every rival you have."
"You already have a bullseye on your back, Lucía. The difference is, this one comes with my men standing behind it."
Lucía stood up, pacing the length of the Persian rug. Every instinct she possessed, honed by years of surviving her stepfather’s violence and the city’s predators, screamed at her to run. Every promise of protection she had ever received had been a trap. Dependence was annihilation.
"This isn't shelter," she said, turning to face him. "This is ownership."
Matteo stood. He moved around the desk, his presence filling the room, eclipsing the light from the fireplace. "It is a contract. A shield. Nothing more."
"I won't be a piece on your board."
"You are already on the board. You have been since your father opened that book. You can play the game, or you can let Carlo take you and your sister off the table." He stopped inches from her. He smelled of rain and cold iron. "Do we have a deal, or do you walk out that door alone?"
Lucía looked at the door. Beyond it lay the dark streets of Porto Nero. Beyond it lay Carlo's hounds, waiting to tear Alba apart just to make Lucía scream.
She turned back to the desk. "I want an addendum."
Matteo raised an eyebrow. "Go on."
"My sister remains outside all family business. Forever. If she is used as leverage by anyone in this house, the deal is void, and I burn the cipher."
"Agreed."
Matteo reached into his coat and withdrew a silver pocket knife. He snapped the blade open. It caught the firelight. Without hesitation, he pressed the sharp edge into the palm of his left hand and pulled. A thin line of crimson welled up, bright and stark against his pale skin.
He set the knife down, picked up a heavy fountain pen, and signed his name at the bottom of the document. Then he pressed his bleeding thumb next to the signature. The red mark stained the cream paper.
A blood contract. The oldest law in Porto Nero. Inviolable.
He turned the pen toward her, his dark eyes locked on hers.
Lucía stared at the blood. Her heart hammered against her ribs like a trapped bird. She was signing away her anonymity. She was stepping into the cage of the most dangerous man in the city.
But Alba would live.
Lucía picked up the pen. Her hand was perfectly steady. She added her clause in sharp, precise cursive at the bottom margin. Then, she took the silver knife. The steel bit into her palm, a sharp, grounding sting.
She signed her name. She pressed her thumb to the paper, her blood mixing with his in the fibers of the page.
Matteo took the contract, folded it, and placed it in his breast pocket. He looked down at her, his expression unreadable, but the air between them had shifted. It was heavier, charged with a sudden, suffocating gravity.
"Welcome to the family, Lucía," he said quietly.
She wrapped her bleeding hand in a handkerchief, refusing to break eye contact. She had survived the night. But as she looked at the cold, beautiful monster standing before her, she realized the true danger hadn't been locked outside the door.
She had just invited it in
