Chapter 3 - The Brass Lock

The lock clicked into place with a heavy, satisfying thud.
Inside Gabriel’s master suite on the fourth floor, the world felt insulated from whatever storm was brewing downstairs. The room was vast, dominated by a king-sized four-poster bed made of dark walnut, floor-to-ceiling bookshelves lined with leather-bound legal texts and Italian history, and an arched bay window that looked out over the glowing gas lamps of Louisburg Square.
A fire was already dying in the brick hearth, casting amber embers across the deep navy carpet.
Sofia did not let go of my apron until we were past the heavy doors. The moment the deadbolt engaged, the adrenaline that had carried the nine-year-old through her public revelation seemed to evaporate all at once. Her knees buckled slightly, and I caught her under the arms, lifting her small frame against my shoulder.
“I’ve got you,” I whispered, carrying her toward the leather sofa beside the hearth. “You’re okay, Sofia. You were so brave.”
She buried her face into the curve of my neck, her small hands clutching the collar of my uniform. Her tears soaked through the thin cotton fabric, hot and fast. She was trembling so violently that her teeth chattered.
“Is Daddy mad at me?” she sobbed, her words muffled against my skin. “Celeste said... she said if I ruined their wedding, Daddy would send me to boarding school in Switzerland. She showed me pictures of it on her phone. It was high up in the mountains with big iron fences. She said bad girls who make up lies about their mothers get sent where the snow never melts.”
A spike of pure, protective rage pierced my chest.
In my six years at the children’s shelter, I had seen every variety of psychological cruelty. I had seen foster parents use shame, isolation, and fabricated guilt to keep vulnerable children compliant. But to watch an adult systematically terrorize a grieving child whose mother had died in this very house—to weaponize her grief against her—made my stomach turn with an intensity I hadn't felt in years.
“Look at me, Sofia,” I said, sitting on the edge of the sofa and pulling her back gently so her tear-streaked face met mine.
She looked up at me with her mother’s large, hazel eyes—eyes that had haunted every framed portrait in the hallways of this house.
“Your father loves you more than his own life,” I said, speaking slowly and deliberately so every word would take root. “He will never send you away. Not to Switzerland. Not anywhere. Do you hear me? He looked at you tonight, and he believed every single word you said.”
“Did he?” she sniffed, wiping her nose with the back of her sleeve.
“He locked the front gates, sweetheart,” I said softly. “You saw him. When Gabriel Romano locks the gates, it means nobody hurts his family. You did the right thing.”
I wrapped a thick cashmere throw blanket around her shoulders and walked over to the adjoining kitchenette to pour a glass of water. As I handed it to her, my mind raced back to the fleeting metallic glint I had seen beneath the umbrella stand on the ground floor.
A dark blue coat with shiny buttons. She dropped something.
If Celeste had been in this house the night Elena Romano fell, and if she had fled down the service stairs in a panic, whatever had rolled under that antique stand had likely been overlooked by the crime scene technicians. Two years ago, Gabriel’s grief had paralyzed him. The police had treated the death as an open-and-shut domestic accident—wealthy socialite slips in silk slippers while fetching a late-night cup of tea. No signs of forced entry. No defensive wounds.
Unless the intruder hadn't forced her way in at all.
Unless the intruder had been invited. Or held a key.
A sudden, sharp knock rattled the heavy oak door.
Sofia flinched, spilling water over her blanket. She scrambled backward on the sofa, pulling her knees up to her chest, her eyes widening in terror.
“Rachel?”
The voice on the other side of the door was not Celeste’s, and it was not Gabriel’s. It was Marco.
I stood up, keeping one hand raised to signal Sofia to stay quiet. I approached the heavy door, leaning my ear against the wood. “Marco?”
“It’s me,” he answered, his gravelly voice low and hurried. “I’m alone. The boss asked me to bring you something, and I need you to confirm a detail before the guests finish clearing out.”
I turned the heavy deadbolt. The lock mechanism slide back with a dry scrape, and I pulled the door open three inches, keeping the heavy brass security chain engaged.
Marco stood in the dim corridor. His tie was loosened, his brow furrowed with deep tension, but his eyes were sharp. In his left hand, he held a sealed manila envelope. In his right, tucked between a pair of latex gloves, was a small, transparent plastic evidence bag.
“Is she calm?” Marco asked, glancing past my shoulder toward the sofa.
“She’s terrified, but she’s safe,” I said. “What is that?”
Marco lifted the evidence bag.
Inside lay a circular object, roughly the size of a half-dollar. It was made of tarnished mother-of-pearl, bordered by intricate filigree in rose gold, with a broken silk shank on the reverse.
A designer button.
“Found it under the umbrella stand by the pantry,” Marco said, his voice dropping to a whisper that didn't carry down the hall. “Just like she said. It’s an antique Italian horn-and-gold button. Custom work. Only one boutique in New England imports this line from Milan.”
My heart skipped a beat. “Marino Imports on Newbury Street.”
“Owned by Celeste’s mother,” Marco confirmed grimly. “I just pulled the manifest from their winter collection two years ago. Celeste had a cashmere trench coat custom-tailored in October, three weeks before Elena died. Midnight blue. With six of these buttons down the front.”
A chill ran across my skin. “Does Gabriel know?”
Marco’s jaw tightened, a muscle jumping beneath his graying stubble. “I haven't told him yet. Right now, he’s in the library with Celeste and her father’s attorney. Old man Marino sent a representative within ten minutes of the gates closing. They’re trying to claim Sofia’s testimony is inadmissible trauma-induced fantasy.”
“It’s not fantasy,” I said fiercely. “She remembered the buttons, Marco! A seven-year-old doesn't invent antique mother-of-pearl buttons!”
“I know that, Rachel. And Gabriel knows it in his gut,” Marco said, leaning closer to the gap in the door. “But we’re dealing with the Marino family. If Gabriel executes Celeste without ironclad, undeniable physical proof, it triggers a full-scale turf war between the North End and South Boston. Blood will run in the streets before dawn. We need more than a button found in a hallway that Celeste visits every week.”
“What do you need?”
Marco handed the manila envelope through the door. “Elena kept a private diary. Not a paper one—she had an encrypted flash drive hidden inside her vanity on the third floor. We never found the password. Gabriel couldn't bear to touch her things after the funeral. But you’ve been cleaning that room for six months.”
I held the envelope. The paper felt heavy, containing something rectangular and rigid.
“Sofia told me her mother used to sing her a song when she put her to sleep,” Marco said, his eyes drilling into mine. “Something in Sicilian. Gabriel doesn't know it—Elena only sang it when they were alone. Sofia might remember the lyrics. The password prompt on the drive is a single phrase in Italian: La custode dei segreti.”
The keeper of secrets.
“I’ll ask her,” I said.
“Be careful, Rachel,” Marco warned, stepping back from the doorway. “Celeste isn't alone in this house. She has loyalists among the catering staff. Don't open this door for anyone until I come back with the boss.”
He turned and walked rapidly down the carpeted hall, his boots making almost no sound.
I closed the heavy oak door, turned the deadbolt, and slid the security chain back into place.
When I turned around, Sofia was sitting up on the couch, staring at the envelope in my hands. The color had returned to her cheeks, but her eyes were fixed on the paper with an expression that was far too old for a nine-year-old child.
“That’s Mommy’s music box,” she whispered.
I stopped. “What did you say?”
May you like
Sofia pointed at the envelope. “Mommy had a little silver stick she called her music box. She told me if anything ever happened to her, I had to give it to the priest at St. Leonard’s.”
She looked up at me, her lower lip trembling again. “Rachel... Mommy knew she was going to fall.”
