By the time Grace Walker realized every man in the courtyard had stopped talking, the estate gates had already closed behind her.

The silence in the study was broken only by the steady rhythm of Titan’s breathing.

"His bloodline?" Grace repeated, her throat dry. "What does that mean?"

"The vault your father designed wasn't just built with steel and mechanical tumblers," Luca explained, leaning against the edge of his desk. "Samuel was paranoid about modern electronic overrides. He constructed a bio-mechanical locking mechanism calibrated specifically to a physical key... and a blood-frequency lock calibrated to his personal DNA."

Grace let out a bitter, disbelieving laugh. "This sounds like something out of a movie, Mr. Moretti. I’m a line cook. I spent the last three years working in a mid-tier diner before taking this estate job."

"And who gave you the referral for this job?" Luca asked sharply.

Grace hesitated. "An agency in Manhattan. Mrs. Gable."

"There is no Mrs. Gable," Luca revealed, pulling a file folder from his desk drawer and opening it. "I had Victor trace the agency credentials two hours ago. The entity that paid your placement fee was a shell company owned by Vance Holdings."

The name landed in the room like a dropped weight.

Grace recognized the name. Arthur Vance was a high-society real estate mogul who regularly appeared in New York business journals. He was known for buying up historic properties—and for the quiet rumors of corporate extortion that seemed to follow his acquisitions.

"Vance was my father's rival," Luca said coldly. "He was the man who ordered the hit on my family twelve years ago. He’s been searching for the Moretti vault for over a decade. He couldn't find Samuel, so he tracked you down and manipulated your employment application to herd you directly into my house."

"Why into your house?" Grace asked, her mind racing.

"Because Vance knows I wouldn't let him touch you if you were here," Luca answered. "He wanted us in the same place. He wanted the key, the dog, and the daughter together so he could force a final standoff."

Grace sank down onto the armchair, burying her face in her hands. Her entire life felt like a elaborate chessboard where she had been moving according to a script written before she was even twenty years old.

Suddenly, Titan stood up.

The giant mastiff let out a low, rumbling growl, his ears pinning back against his head. He stepped over to Grace and began nuzzling aggressively at the heavy leather collar around his neck.

Luca watched the dog closely. "What is he doing?"

"He used to do this when his collar was too tight as a puppy," Grace said, reaching out with trembling hands to calm the dog. "Wait... Titan, hold still."

Grace turned the gold M buckle on the collar. As she inspected the thick leather underside, she felt a strange, rigid bump sewn into the lining near the brass rivets.

"Luca," Grace said, her voice barely above a whisper. "There's something inside the leather."

Luca immediately produced a small pocket knife, stepping beside her. With practiced precision, he sliced through the reinforced stitching along the inner band of the collar.

A small, silver object slipped out and fell directly into Grace’s open palm.

It was a custom-carved steel key, intricate and heavy, its head shaped in the likeness of a oak leaf—the exact symbol Samuel Walker used to carve into the corner of every wooden table he ever built.

Tucked behind the key was a tiny, tightly rolled piece of oilpaper.
