THE MAFIA BOSS'S SECOND IN COMMAND CLAIMED CLARY WAS LYING, BUT WHEN THE HOSTAGE PHOTO REVEALED A FAMILIAR BRASS LION, HIS SMILE DISAPPEARED.

“What were you planning to do with those recordings, Arthur?”

Declan Knox did not raise his voice. That frightened me more than shouting would have. He stood in the doorway of his private bathroom, black tattoos disappearing beneath the cuffs of his white dress shirt, holding the transmitter as if it weighed a hundred pounds. On the other side of the marble wall, my brother was alive. Upstairs, five hundred guests were still celebrating a birthday, unaware that someone had turned the house beneath their feet into a prison.

Arthur Bell gave a crooked smile. “The same thing you would have done. Protect the business.”

“From what?”

“From yourself.”

Two guards held Arthur at the threshold. He had stopped reaching for his phone, but his eyes kept darting toward the ventilation grille above the door. Declan noticed. With two fingers he indicated the grille, and his security chief, Celia Ward, stepped into the corridor to speak into her radio.

I pressed my palms together so hard that the little listening device left marks on my skin. “Please,” I whispered. “Can I see Tommy?”

Declan turned. For a heartbeat, the intimidating man the newspapers called the king of the waterfront vanished. He looked like someone who had only just understood how cruelly his home could be used.

“Yes,” he said. “You should have been with him already.”

“Boss,” Arthur interrupted, “the boy owes money to dangerous people. She brought this into your house.”

Declan's gaze returned to him. “You knew where the boy was kept.”

“I was managing a situation.”

“You were managing a kidnapping.”

Arthur flinched. It was a small movement, but I saw it.

A medic came through the connecting corridor with a collapsible stretcher. I followed her, limping from the stiffness in my legs after hours kneeling on the bathroom floor. Beyond a locked service door lay a passage I had never known existed. Its concrete walls smelled of damp mortar and old heating pipes. At the far end, a guard held open a metal door beneath a brass lion plaque.

“Clary?”

Tommy was sitting on a narrow bed. He was twenty-one, though he looked younger under the sickly fluorescent light. His hair stuck to his forehead. There was a bruise on one cheek and a crust of blood beneath his nose. But he was sitting up. He was breathing. He was looking at me.

I crossed the room before anyone could stop me.

“Oh, Tommy.”

He threw both arms around me. His body shook so violently that I could hardly hold him.

“I knocked,” he sobbed against my shoulder. “I heard you singing and I knew it was you. I knocked three times.”

“Our signal,” I said, pressing my face into his hair. “You remembered.”

“I thought maybe you wouldn't hear.”

“I heard.” My voice broke. “I heard you.”

The medic gently asked him to lean back so she could examine his injuries. I stayed beside the bed, holding his hand while she checked his pupils and pulse and asked about food, water, and medication. Tommy admitted he had received water and sandwiches, but sometimes a guard made him wait an entire day. He said no one had explained when he would be released.

“Don't tell them about the folder,” he whispered suddenly.

“What folder?”

His eyes flew to the doorway. “Not here.”

The medic looked at me, then at the guard. “He needs medical care outside this building. And neither of them should be questioned in front of anyone connected to the confinement.”

Celia appeared behind her. “An ambulance is coming through the south service entrance. The police have been called.”

Arthur's distant voice erupted in protest. “You called the police into a Knox residence?”

Declan answered, calm and unmistakable. “A young man was locked in my wall. Yes.”

I looked up. Declan stood a few steps away, careful not to crowd Tommy. He had bloodshot eyes. Perhaps he had been awake as long as I had. Perhaps he had spent his birthday believing the people closest to him were loyal.

Tommy stared at him. “You're Declan Knox.”

“Yes.”

“They told me you ordered it.”

Declan went still. “Who did?”

“The man with the silver ring. Arthur. He said if you knew my name you'd have me sent to the river.”

“I didn't order your confinement,” Declan said. “I understand why that may be difficult to believe.”

My brother looked at the hand holding mine. “He wanted Clary to put a microphone in the bathroom. I kept saying she wouldn't.”

“You were right,” Declan answered.

Celia's radio crackled. “North stairwell secure. Ballroom doors staffed. Technical team checking the event feed.”

Something in Declan's expression sharpened. “The event feed?”

She hesitated. “Arthur's people requested a live audio connection from the private suite to the birthday stage.”

I remembered Tommy's voice through the transmitter: He wanted Clary to record what you said about the five hundred guests tonight.

“Why would they need that?” I asked.

“Tonight,” Declan said slowly, “I was supposed to announce who would control the Knox Harbor Relief Fund for the next five years.”

I knew the fund. Its posters hung in the staff entrance: housing repairs, school supplies, winter heating. Declan's father had started it after the East Pier warehouse fire. The fund was spoken of with reverence, though I had met housekeepers who said their relatives had waited years for promised assistance.

Arthur had overseen the fund's administration for a decade.

Declan looked at Celia. “Who prepared my speech?”

“Arthur approved the production team and the final program.”

“Stop the presentation.”

Celia spoke rapidly into her radio. Then an answer came back, too low for me to understand. Her jaw tightened.

“What?” Declan demanded.

“The screen system is locked on a timed sequence. The technicians can't cancel it from the stage.”

A cold sensation spread through my chest.

From the corridor came a muted burst of applause. The ballroom was two floors above us, but sound traveled down the old service shafts. The guests had begun calling for their host.

“What sequence?” I asked.

Celia checked her phone. “A birthday tribute. Scheduled for ten fifteen.”

Declan looked at the wall clock. Ten twelve.

“Evacuate the room?” one guard suggested.

“Not by causing a crush,” Celia said. “Five hundred people, narrow west stair, a balcony. We need exits opened and staff stationed.”

Declan nodded. “Do it properly. Tell them there's a technical and fire-safety concern. No speeches. No dramatic announcements.”

I could scarcely believe the room still contained ordinary decisions: which stairs to use, where to place medics, who would take Tommy's statement. My life had narrowed to a single fear for three nights, and now every second carried a different one.

Declan turned toward me. “Clary, the device they gave you. Did you switch it on?”

“No. I tried twice, but I couldn't make myself hide it. I only held it.”

“Good.”

His relief was so plain it almost hurt. Then he corrected himself. “I mean, you should never have been put in that position. What happened to you and your brother is not a test you were required to pass.”

I stared at him, unsure how to accept kindness without waiting for its price.

Tommy touched my wrist. “Clary, look in my shoe.”

The medic lifted an eyebrow. Tommy gave a tiny, embarrassed shrug. “They searched my pockets.”

Inside the worn lining of his left sneaker was a folded rectangle of blue paper, softened by sweat. I opened it carefully. Numbers and dates filled one side. On the other, in Tommy's hurried handwriting, were four words:

DON'T LET THEM TOAST.

Below that: HARBOR FUND — ORIGINAL BOOK.

“What's the original book?” Declan asked.

Tommy swallowed. “They made me copy figures from it. I didn't know what they meant. I only knew they were scared you would ask to see it.”

A guard hurried into the doorway. “Mr. Knox. We've found the media rack. Someone removed the manual controls.”

The clock changed to ten thirteen.

Declan looked at Celia. “Whoever is still upstairs gets out. I don't care what the screen says about me.”

“Understood.”

I watched him turn away. For the first time since entering the mansion nine months earlier, I saw a man choosing something other than appearances. He was abandoning his own birthday party, not because a maid had sung beautifully, but because a child of his household had been used as leverage and the people upstairs might be in danger.

At the corridor entrance, Arthur called to him from between the guards. “You think turning off a projector stops this? You're already too late.”

Declan stopped. “For what?”

Arthur smiled without warmth. “Five hundred witnesses, Declan. That's what you invited tonight.”

The first fire alarm rang above us. Not a full evacuation bell. One sharp, deliberate tone.

Then the mansion lights blinked.

Celia's radio screamed with overlapping voices. “The screen is live. It's playing the boss's voice.”

Declan closed his eyes for half a second. When he opened them, he gave orders that were precise and calm. “Keep the doors open. No one uses the west stair. And record every second of that playback.”
