THE MAFIA BOSS FOUND HIS MAID TREMBLING BESIDE A BLOODSTAINED CABINET, BUT ONE HIDDEN MESSAGE SUGGESTED DANGER WAS ALREADY INSIDE HIS HOME.

"Camila!" I shouted into the grille.

Only silence answered. Ronan caught my elbow before I could press my injured hand against the cold metal.

"Elena, listen to me. Did you see her?"

"No, but I heard her. I know my sister's voice."

We stood on the second-floor landing, with the dead wing across the courtyard and the mansion's pale marble stretching around us like a museum after closing. The vent had been painted the same cream color as the wall. Dust crowded its corners. Behind it, air moved through an old service shaft.

Ronan put his ear close to the grille. Nothing. He tried calling her name once, then stepped back.

"The east wing has its own ventilation system," he said. "It shouldn't connect here."

"But it does."

"Then someone changed something without telling me."

The thought seemed to trouble him more than he wanted to admit. He was a man who controlled shipping companies, private investments, and half the construction cranes along the river. Yet the house he inherited from his father was keeping secrets from him.

He placed a call to a man named Miles Keene, the estate's head of security. I grabbed his arm before he could finish.

"Please don't tell him where we are."

Ronan studied me. "Do you have a reason not to trust Miles?"

"I have a reason not to trust anyone Grant hires."

That stopped him. He canceled the call and sent a short message instead, asking Miles to meet him in the main foyer. Then he led me into the guest suite, promised he'd return, and locked the door from the hall only after showing me how to open it from inside.

The room was larger than my apartment. A fire burned in a white stone hearth. Fresh flowers stood on a table near the bed, and the curtains were the color of winter clouds. None of it made me feel safe. Luxury didn't matter when a locked door could become a cage.

I sat on the edge of the mattress and looked at the stitches in my hand. Dr. Shaw had placed six. She had told me to keep the wound clean and call if the swelling increased. Under the bandage, my fingers throbbed with every heartbeat.

I waited six minutes.

Then a note slid under the door.

I thought Ronan had sent it, but the handwriting was different. Three words were written in black ink: YOU WERE WARNED.

A second later, the lights went out.

I rushed to the door and pulled it open. The corridor was empty, dimly lit by emergency lamps. At the far end, a small red indicator blinked above the stairwell. Somewhere downstairs, an alarm began to chirp.

"Mr. Vale?" I called.

No answer.

I should have remained in the room. I knew that. But I'd spent eleven months imagining Camila trapped somewhere and calling for me. Now I had heard her. Staying still felt impossible.

I followed the corridor toward the east-wing connection. It ended at carved double doors secured with a chain and electronic keypad. The keypad glowed despite the outage. A handwritten sign read RESTRICTED — STRUCTURAL REPAIRS.

I touched the chain.

"Elena."

I spun around. Mrs. Wynn, the housekeeper, stood beneath a flickering lamp. She was in her sixties, with silver hair pulled into a severe bun and a face that looked carved from patience.

"You shouldn't be here," she said.

"I heard someone."

Her expression changed. "A man?"

"My sister."

For a moment, all the color left her face. Then she straightened and reached into the pocket of her cardigan.

"Come with me. Quietly."

I hesitated. Mrs. Wynn had been kind to me from the day I arrived. She made sure I ate after double shifts and told the other maids not to tease me for asking questions. But kindness, I was learning, did not guarantee innocence.

"Why?" I asked.

"Because the cameras on this floor went dark thirty seconds ago. The house doesn't do that by accident."

She opened a narrow servants' door behind a tapestry and ushered me into a corridor no wider than my shoulders. Old radiators ticked along the wall. I could hear people running on the other side, their voices muffled by brick.

"You knew about this passage?" I asked.

"I've worked here thirty-one years. There isn't a passage I haven't swept."

"Then tell me how to reach the east wing."

She stopped. "I can't."

"My sister is there."

Mrs. Wynn looked away. "That wing isn't empty. But it's not what you think."

A door slammed somewhere close. She pushed me behind a shelf stacked with spare linens and raised a finger to her lips. Through the narrow crack between boards, I saw Grant Mercer appear with Miles Keene.

"The girl heard the voice," Grant said.

Miles swore under his breath. "You told me the recordings were disconnected."

"They were. Someone switched them on."

Recordings.

The word struck harder than any slap. My knees almost gave way. Was the voice I'd heard just another trick? Was Camila not here at all?

"Find the maid," Grant ordered. "I want her phone and everything she took from the library."

"Vale is asking questions."

"Ronan asks questions. Then he signs whatever I put in front of him. That's been the arrangement for years."

Their footsteps moved away.

Mrs. Wynn closed her eyes. She looked as though she had just lost an argument with herself.

"Come," she whispered.

She led me down two flights of narrow wooden stairs to a storeroom off the old kitchen. Flour sacks and crates of bottled water filled the shelves. There she switched on a battery lantern and took an envelope from a false bottom in a tin of tea.

"Your sister gave me this before she disappeared. I promised not to open it until someone came looking for her."

My hands shook as I pulled out a small photograph and a key. The photograph showed Camila standing beside Ronan's father, Henry Vale, in a hospital room. He looked frail, a blanket pulled high over his chest. At the edge of the frame stood Grant Mercer, smiling into the camera.

On the back, Camila had written a date and a sentence: HE WASN'T TAKING THE MEDICINE HE THOUGHT HE WAS.

"What does this mean?" I whispered.

Mrs. Wynn pressed her fingers to her lips. "I watched Mr. Vale get worse after Mr. Mercer took charge of his doctors. Your sister asked me to save the empty medicine bottles. I was frightened. I didn't."

"Then why give me this now?"

"Because after he died, I found a bottle hidden in the fireplace ashes. I kept it this time."

"Where is it?"

"Somewhere Grant won't think to look."

She put a small brass key in my palm. "The old conservatory. There's a cabinet beneath the sink. It opens the bottom drawer."

Before I could thank her, the storeroom door opened.

Ronan stood there, breathing hard. His sleeves were rolled to his elbows, and he had a flashlight in one hand.

"I've been looking for you," he said to me. "Both of you."

Mrs. Wynn took one step forward. "Mr. Vale, I've done something I should have done a long time ago."

Ronan looked at the photograph in my hand. His face changed when he recognized his father.

"Where did you get that?"

"Camila left it," I said. "She was worried about your father's medicine."

He stared at the image. "My father refused visitors during his last weeks. Grant told me it was because he didn't want me to see him like that."

"Did you believe him?" I asked.

"I wanted to."

The honesty in his voice made me look up. For the first time, I saw what his grief had done to him. He had spent half a year trying not to think about a closed door. Now that door was all we could think about.

"The outage wasn't accidental," he said. "Someone triggered the east-wing breakers. Miles insists it was a fault, but the control panel shows a manual override."

"Miles was with Grant," I said. "I heard them talking. They were looking for me."

Ronan turned toward Mrs. Wynn. "Who else knows these passages?"

"Only the oldest staff," she answered. "And Mr. Mercer."

"Then we're going to the conservatory," he said.

We moved through a covered walkway into a glass room behind the kitchens. The rain had stopped, leaving beads of water on the roof. Orange trees stood in blue ceramic pots. Their leaves made soft shadows across the floor. I remembered seeing Camila's photograph of that room years earlier, when she first told me she'd found a job with people who treated her kindly.

Beneath a deep porcelain sink, I found the cabinet Mrs. Wynn described. The key turned reluctantly. Inside the bottom drawer lay a brown pharmacy bottle wrapped in a dish towel, a folded invoice, and a narrow strip of medical tape marked with my sister's handwriting.

The invoice showed a private clinic called Bellwether Medical Services. It had billed the Vale family for weekly treatments no physician had mentioned to Ronan. Below the clinic's name was a payment reference marked BLUEBIRD.

Ronan unfolded the invoice. "I've seen this company before."

"Where?"

"In one of Grant's acquisition files. He said it was a healthcare investment the foundation was considering."

Mrs. Wynn touched the glass roof as the first distant thunder sounded. "Your father said that foundation was supposed to help families," she whispered. "He would never have wanted this."

Ronan took a photograph of the invoice with his phone, then opened a secure message thread. "I have a friend in forensic accounting. She doesn't answer to Grant. I'll ask her to trace these payments."

I looked at him. "You're trusting me now?"

"I'm trusting what I can verify. There's a difference."

He said it gently, not as a rebuke. I found myself liking that more than an easy promise.

Behind us, the conservatory door clicked shut.

Mrs. Wynn whirled around. The handle wouldn't move.

A mechanical voice announced from a speaker overhead, "Fire suppression system armed. Please evacuate."

The sprinklers didn't turn on.

Instead, a chemical smell poured through the ventilation grate beneath the sink.

Ronan pulled his jacket over my mouth and nose. "Get low. Now."

Through the fogging glass, I saw Grant Mercer standing on the walkway outside. He wasn't alone. Miles Keene stood beside him with a black device in his hand.
