**THE MOMENT THE MAFIA BOSS’S FIANCÉE CALLED ME “A NOSY LITTLE CLEANING GIRL,” I WAS STANDING BESIDE HIS DEAD BROTHER’S CASKET—HOLDING THE WATCH THAT WAS SUPPOSED TO BE ON HIS WRIST.** The private viewing had been closed to everyone except family.

“How do you know what we’re going to find down there?”

Anthony’s voice didn’t echo in the chapel. It didn’t need to. It simply absorbed all the air in the room.

Bianca’s eyes darted toward the security men. Then to Anthony’s mother. Finally, they landed on me.

“I don’t know what you’re talking about,” Bianca said. Her voice was too high. Too thin. “I just think it’s disrespectful to tear apart your father’s legacy while your brother is lying right here.”

Anthony didn’t argue.

He didn’t yell.

He simply reached out and took the large brass key from his mother’s trembling hand.

“Stay here,” Anthony told his mother gently. He kissed her forehead. “Do not let anyone leave this room. Especially her.”

He didn’t point at Bianca. But two massive men in dark suits immediately stepped in front of the chapel’s double doors.

Bianca folded her arms, her knuckles turning white.

Anthony turned to me.

“Kate. Walk with me.”

I shouldn’t have gone. I was making fifteen dollars an hour to wipe down folding chairs and empty trash cans. But my uncle had taught me to trust my eyes, and my eyes told me that whatever was happening here, a man had been murdered for it.

And I was the only one who noticed how.

I followed Anthony out the side door of the funeral home, into the freezing Chicago rain. Two security guards flanked us, their coats pulled tight against the wind.

A black SUV idled at the curb.

Anthony opened the door for me. It wasn’t a gesture of chivalry; it was a command.

I got in.

He slid in beside me, tapping the glass partition. The driver pulled away from the curb immediately.

“Where are we going?” I asked.

“The old financial district,” Anthony said, his eyes fixed on the rain-streaked window. “My father didn’t trust modern banks. He kept a private locker at the Sterling Depository. It’s a secure facility for people who prefer paper ledgers and physical keys.”

I looked down at the tiny brass key in Anthony’s hand.

“And the room beneath it?” I asked.

“It’s not a room,” Anthony said softly. “It’s a sublevel vault. Only two people in the world had access to it. My father, and the depository manager.”

“Not Daniel?”

“No.” Anthony’s jaw tightened. “Which means Daniel didn’t just happen to have that tiny key. He stole it. Or he was given it right before he died.”

We arrived at a massive, gray stone building. No signs. No grand entrance. Just a heavy steel door in an alleyway.

Anthony bypassed the front desk entirely, flashing a heavy silver ring to a man standing near the elevators. The man nodded and swiped a card.

We descended.

The air grew cold.

The elevator doors opened to a corridor lined with floor-to-ceiling brushed steel lockers.

Anthony walked to locker 402.

He inserted the large brass key his mother had given him.

It turned with a heavy click.

He opened the door.

I expected stacks of cash. Passports. Diamonds.

It was entirely empty.

Anthony stared at the barren steel shelf.

“He cleared it out,” Anthony whispered. “Daniel cleared it out.”

He looked down.

At the bottom of the locker was a seamless steel floor. But in the back right corner, barely visible under the harsh fluorescent light, was a tiny keyhole.

The room beneath it.

It wasn’t a basement. It was a hidden compartment built into the foundation of the locker itself.

Anthony knelt.

He inserted the tiny brass key I had extracted from his brother’s watch.

It fit perfectly.

He turned it.

A section of the steel floor popped up.

Anthony reached in and pulled out a heavy, dark wooden box.

He placed it on the floor between us and opened the lid.

Answer one.

The box didn’t hold money. It didn’t hold weapons.

It held a stack of faded letters, tied with a black ribbon.

Open two.

Who wrote the letters? And why did Daniel die to protect them?

Anthony untied the ribbon. He opened the first envelope.

He read the first line, and his entire body went rigid.

“Mr. Romano?” I asked cautiously.

He didn’t answer. He just handed me the letter.

I looked at the elegant, looping handwriting.

My dearest Daniel, Bianca knows. She found the medical records. If Anthony marries her, the Russo family will own the shipping lines legally. You have to tell him the truth about her bloodline. Protect Leo.

I stopped reading.

“Who wrote this?” I asked.

Anthony looked at me, his eyes hollow.

“My father.”

The reversal hit me like a physical blow.

His father hadn’t died nine years ago of natural causes. He had been murdered too. Because he knew Bianca’s secret.

But before Anthony could speak, a metallic clatter echoed down the corridor.

We both looked up.

One of Anthony’s security guards was lying on the floor, bleeding from the head.

Standing over him was the depository manager.

And he was pointing a suppressed pistol directly at Anthony’s chest.

“Put the letters back in the box, Anthony,” the manager said.
