THE MAFIA BOSS'S FIANCÉE THREW HIS HOUSEKEEPER OUT—THEN A BIRTHDAY CAKE EXPOSED THE SECRET BENEATH HIS MANSION

Vanessa's expression changed so quickly I almost missed it. One second she was the perfect bride in red silk, chin lifted, diamond ring catching the kitchen light. The next, she looked like a woman who had heard a gun being cocked behind her.

“Margaret is confused,” she said. “She's seventy. She's upset. You cannot seriously be taking this—”

“Stop.” Luca didn't raise his voice. He didn't need to. The security guard beside the pantry straightened as though somebody had pulled a string through his spine.

Mrs. Russo flinched. Luca noticed and lowered himself beside her again.

“I'm not angry with you,” he told her. “Whatever my father made you promise, you don't owe that promise to a dead man if it puts you in danger.”

Her eyes filled. “He wasn't trying to hurt you, sweetheart.”

“Then why did he lock the cellar?”

She looked at the suitcase. “Because he finally understood what he'd helped build.”

The back door swung open. Cold November air swept across the tiled floor, bringing the smell of wet leaves. Behind Luca, the last notes of the engagement quartet drifted through the house. Forty people were still waiting to discover whether dinner would continue. It felt obscene that someone might be asking for another glass of champagne while Margaret Russo trembled on the steps.

Luca turned to his head of security, a broad, gray-haired man named Gabriel Torres. “Nobody leaves the property until I speak to them. No one enters the cottage. And find out who authorized construction.”

Gabriel nodded. “Yes, boss.”

“Luca,” Vanessa said, “you are humiliating me in front of our guests.”

He stared at her. “You threw the woman who raised me out of her home. We're well past embarrassment.”

I held the cake against my ruined uniform. My arms ached. Luca glanced at me and seemed to realize I was still standing there.

“Emily, put that down. Please.”

It was the please that nearly undid me.

I set the cake on a stainless-steel counter. The blue frosting had smeared, but the words HAPPY 70TH, MARGARET were still readable. I had spent an hour piping those letters, remembering how Mrs. Russo always said nobody bothered celebrating people after they got old. I hadn't known a cake could become evidence.

“Get her a clean uniform,” Luca told the kitchen manager.

“No,” Mrs. Russo whispered. “Emily should stay. I need her to hear this.”

Vanessa took a step toward us. “This is ridiculous.”

“Then you won't mind listening,” Luca replied.

Margaret pressed her fingers to the collar of her wool coat. “Your father gave me a key the night he died. He said I was to keep it hidden until the Bellinis came asking about the cellar.”

Luca's jaw tightened. “He mentioned the Bellinis by name?”

She nodded.

Vanessa laughed, a thin, brittle sound. “My family has done business with yours for decades. That's hardly a revelation.”

Margaret ignored her. “I sewed the key into the lining. I thought it was safe. Yesterday, your father-in-law came with two men. They searched my cottage. They turned out drawers and opened the walls behind my stove. When they didn't find it, he said I could give him the key or I could lose my home.”

“Why didn't you call me?” Luca asked.

“Because he said you were already involved.”

The silence afterward was different from the silence in the dining room. It was the kind that came before a verdict.

Luca rose. “Gabriel, take Mrs. Russo upstairs to the blue sitting room. Post two guards. They answer only to you.”

“I can walk,” Margaret protested.

“I know you can.” Luca offered his arm. “You don't have to do it alone.”

She gave him a small, sad smile. I wanted to cry again, but there was no time. When Gabriel escorted her inside, Vanessa caught Luca by the sleeve.

“You can't turn my father's business visit into a conspiracy because an old woman misunderstood him.”

“Then tell me what he was looking for.”

“I don't know.”

“Look at me and say that.”

She did. For a moment, I almost believed her.

Then her gaze dropped to my apron pocket.

It was a tiny movement, but Luca saw it. So did I. Margaret had gripped my hand earlier while I helped her carry the suitcase outside. I remembered the small pressure of something hard against my palm. At the time, I thought she'd handed me a coin. I had tucked it away without looking.

My pulse kicked.

Vanessa's gaze sharpened. “Emily, what's in your pocket?”

I put my hand over the fabric.

“Nothing, ma'am.”

“Show me.”

“She's not taking orders from you anymore,” Luca said.

Vanessa's face reddened. “You are choosing a maid over your future wife?”

“No. I'm choosing the truth over someone who keeps lying to me.”

She slapped him.

The crack echoed against the tile. My breath stopped. Luca didn't move. A red mark bloomed on his cheek, but his expression stayed terrifyingly calm.

“Get your coat,” he said. “Gabriel will escort you to the guest wing. You will stay there until your father arrives.”

“You can't keep me prisoner.”

“You can leave with your driver once security clears the gate. But you are not walking through my house or speaking to my staff again tonight.”

Vanessa looked as though she might hit him a second time. Instead she smiled at me.

“You think you've won something, Emily? You have no idea what you're holding.”

She walked away before I could answer.

Luca waited until her heels faded down the hall. Then he looked at my pocket.

“Do you?”

I shook my head and pulled out a small brass object wrapped in a strip of faded blue cloth. A key. Its head was engraved with a rose and the number nine.

Luca took one look and went pale.

“Where did you get that?”

“Mrs. Russo must have given it to me.”

He held it carefully, as if it might break. “My mother had a necklace with this exact rose. She wore it every day until she died.”

“What does the nine mean?”

He stared at the engraving. “I don't know. But I was nine when she died.”

We walked to the library together. It was the first time I'd entered the room beside him rather than to clean it. The fireplace was dark. The old wooden rocking chair stood untouched beside it, its cushion faded from years of sunlight.

Luca stopped in front of the chair. “Mrs. Russo told you never to touch this, didn't she?”

“Yes.”

“My mother used to sit here and read to me.”

He knelt and ran his hand beneath the seat. I heard a soft click. A narrow compartment opened, revealing an envelope wrapped in waxed paper.

Across the front, in elegant handwriting, were four words:

FOR LUCA. WHEN READY.

Luca broke the seal. Inside was a photograph of two men standing outside a brick warehouse. One was his father, younger and smiling. The other was a broad-shouldered man I recognized immediately from the engagement portraits displayed throughout the mansion.

Victor Bellini. Vanessa's father.

On the back of the photograph, someone had written: THE NIGHT WE BURIED THE WRONG MAN.

Luca stared at the words for a long time. Then his phone vibrated.

An unknown number had sent him a photograph taken through the library window. It showed the two of us standing beside the rocking chair, the envelope open between us.

Beneath the picture was a message.

THE KEY ISN'T YOURS. GIVE US THE GIRL BEFORE MIDNIGHT.

Luca lifted his eyes to mine.

For the first time since I'd met him, I saw fear.
