THE MAFIA BOSS NOTICED BLOOD ON HIS MAID'S BANDAGE, BUT WHEN HE ASKED WHO WAS RESPONSIBLE, SHE BEGGED HIM NOT TO SAY ANOTHER WORD.

Ronan entered the old treatment corridor at eleven forty-two. He wore no jacket, only a black shirt with the sleeves rolled to his elbows. Two guards escorted him, but I could tell from the way they avoided his eyes that they weren't his men anymore.

Celeste stood beside me with the pistol hidden beneath her folder. The red mark on my cheek had begun to swell. Beyond the steel door, Sofia sat so quietly I kept checking to hear her breathing.

“Show me both sisters,” Ronan said.

Celeste nodded to Malcolm, who emerged from the service lift. He unlocked Sofia's door. My sister stumbled into the corridor, thinner than I remembered, with a bruise along her jaw and the same fierce brown eyes she'd always had. I crossed the distance between us before anyone could stop me.

She smelled of stale linen and antiseptic. Her arms closed around my shoulders, and for one brief, impossible moment, we were in our old kitchen after a bad day, holding each other while the kettle boiled.

“You shouldn't have come,” she whispered.

“Too late.”

She tried to smile. I couldn't.

“Now,” Celeste said, “the transfer.”

Ronan held up the document she'd left on his desk. “All fourteen pages, including the board authorization. My signature is on the final page.”

“Give it to me.”

“First, let them leave.”

Malcolm stepped forward. “You aren't negotiating, Vale.”

Ronan ignored him. “Celeste, I know you wanted my father to make you his successor. I know he promised you the company if you kept Westbank quiet. But you can't own it from a cell.”

“Your father promised many things,” she said. “He meant almost none of them.”

“Then don't become him.”

The words struck her harder than I expected. For a moment she looked nearly young, as if he had found a place inside her that had never stopped wanting August Vale's approval. Then the softness was gone.

“Put the papers on the floor.”

Ronan did. Malcolm picked them up and examined the last page.

“It's signed.”

Celeste took the folder. “You see? Reasonable decisions aren't so difficult.”

“Let them go,” Ronan repeated.

“You can all leave together,” she said, “after the vote.”

She pointed toward the treatment rooms. Malcolm pulled the weapon from her folder, and suddenly I understood the truth. She had never intended to honor the bargain. We were witnesses. Witnesses were expensive to keep alive.

“You said we'd walk away,” I protested.

“I said you would be released. Time is a flexible concept.”

Ronan moved closer. Malcolm raised the pistol. A new voice echoed down the corridor.

“State police. Nobody move.”

Detective Naomi Reyes stood at the lift entrance, a badge held high. She was in her forties, with dark hair pulled back and a gray raincoat damp at the shoulders. Two uniformed officers waited behind her. Their presence made the air change.

“Mr. Vale,” she said, “I need everyone to step away from the door.”

Celeste smiled, recovering almost instantly. “Detective, thank goodness. We've been dealing with an employee who broke into restricted rooms. She attacked me and threatened to expose confidential medical records. Ronan was trying to calm her down.”

Naomi looked at my swollen cheek, then at Malcolm's weapon. “Set that on the floor.”

“I'm the director of security,” Malcolm said. “It's licensed.”

“Then you understand a lawful instruction.”

He set it down. One officer stepped forward to secure it, but Malcolm shifted, bumping the officer into the wall. The lights went out.

For one heartbeat the corridor was pure black. Someone screamed. I grabbed Sofia's arm and dragged her to the floor as a gunshot cracked against the tiles. Ronan shouted my name. Emergency lights blinked on, painting everything red.

Naomi had one officer pinned behind a cart for cover. Malcolm had disappeared through the service door. Celeste, still holding the signed documents, was gone.

“Move!” Naomi shouted. “Everyone out!”

A smell reached me—hot electrical insulation, then smoke. The lights in the ceiling sputtered. Somewhere above us a fire alarm began to wail.

Ronan found us kneeling beside the wall. He helped Sofia stand, then turned to Naomi. “The east service lift connects to the conservatory. That's where the fire's starting.”

“Go back toward the kitchen stairs,” she said. “My people are clearing the grounds.”

But when we reached the stairwell, smoke poured down from above. The door slammed shut as though the house itself had rejected us.

“We can't go that way,” I coughed.

Ronan pulled his shirt over his mouth. “The old inspection tunnel. We can reach the library from the lower passage.”

Sofia grabbed his arm. “No. The pump line runs along that tunnel. If they opened the river gate, it could flood.”

“Then what do you suggest?”

She pointed to a narrow maintenance hatch behind the cabinets. “That leads to the greenhouse drainage corridor. I saw it when they moved me.”

We crawled through the hatch one by one. Naomi remained with us while her officers secured the nearest stair and called the fire service. The passage was barely high enough to stand. Hot air pushed through the grating overhead, and the stone beneath our shoes trembled with distant machinery.

“Malcolm is burning the evidence,” Sofia said as we hurried. “He told Celeste that if the board found the original records, everything would collapse.”

“What original records?” Naomi asked.

“Westbank manifests. Water tests. Payoffs. They hid the paper trail in the old control room because nobody knew the room was still there.”

Ronan glanced at her. “You found it?”

“Not all of it. I found the index.”

We reached a narrow ladder just as something thundered overhead. Dust fell like gray snow. From above came a woman's cry.

“Help! Somebody!”

I knew that voice. “Mrs. Finch.”

Ronan looked up at the hatch above the ladder. “The linen room is on the other side.”

Naomi caught my arm. “Elena, you and Sofia keep moving. My officers will get her.”

But the nearest officers were aboveground, and Mrs. Finch was calling again, weaker now. She had risked her job for me, hidden my identity, and tended my injuries when she had no reason to expect a reward. I couldn't walk away from her voice.

“I'm coming,” I called.

I climbed before anyone could stop me. Ronan followed, cursing softly. We emerged into a smoke-filled service hall where burning insulation hung from the ceiling. Mrs. Finch lay beside a fallen rack, her ankle trapped beneath a metal frame. A few feet away, flames licked at the linen shelves.

“Oh, you foolish girl,” she gasped when she saw me. “I told you to stay alive.”

“Then stop making that so difficult.”

Ronan lifted the rack while I pulled her free. Mrs. Finch cried out, then bit down on the sound. We each took one of her arms and headed toward a door marked SERVICE EXIT. It was chained from the other side.

“Malcolm,” Ronan muttered.

He kicked at the lower panel. Once. Twice. On the third blow, the old wood split enough for him to reach the chain. It scraped loose and fell, and fresh air rushed through the opening.

Firefighters were already running across the lawn. We stumbled into the rain, carrying Mrs. Finch between us. A medic hurried forward. Behind us, black smoke lifted through the conservatory roof, turning its shining glass into a cracked, angry sky.

I found Sofia sitting on the wet grass beside Naomi. She stood when she saw us and held her arms open. I stepped into them without speaking.

“There's something I haven't told you,” she whispered.

“Not now.”

“Now. Because I don't know whether I get another chance.”

She pressed a small folded card into my hand. It was a museum inventory tag, its edges softened with sweat. On the back was a sequence of letters and numbers.

“They kept asking me for a code,” she said. “The room under the pumps has an old mechanical ledger cabinet. My job was to restore the index, and I realized the cabinet's numbering matched Mara's notes. Celeste thought I knew how to open it.”

“Do you?”

“I know the first half. I thought the rest was gone.” Sofia looked past my shoulder toward Ronan. “Then I heard you played Mara's recording.”

Ronan knelt beside us. His face was streaked with soot. “What does her recording have to do with the code?”

“She says, ‘Follow the water.’ It isn't just a warning. It's part of her key.” Sofia swallowed. “I need the drawing on the back of that photo of her and you at the dock. She made me examine it when I was cataloging the archive.”

Ronan stared at her. “That photograph has been in my library for years.”

“And underneath the cardboard backing,” Sofia said, “is a map.”

The fire service commander shouted for everyone to move farther from the building. An upstairs window shattered, and flames blew outward into the rain. I thought of the library, the photograph, Mara's letter, all the things a frightened girl had tried to save.

Naomi approached, speaking urgently into her radio. “The road cameras caught a vehicle leaving through the south gate. Celeste's car. Malcolm may be with her.”

Ronan stepped toward the burning house, but I caught his wrist.

“No,” I said. “We are not going back in there.”

“The photograph—”

“Your sister died trying to get someone to listen. You listened. That doesn't mean you have to die proving it.”

He looked at the flames, then at me. Finally he stopped fighting my grip.

A firefighter emerged from the side entrance carrying a scorched wooden box. “Anyone recognize this?” she asked. “Older lady said it was in the linen safe and not to leave it.”

Mrs. Finch, already on a stretcher, lifted one hand triumphantly.

“People think housekeepers only remember where the napkins go,” she called hoarsely. “They forget we know where everyone hides the things they love.”

Ronan opened the box. Inside, wrapped in a tea towel, was the photograph of him and Mara.

He turned it over. Under the loosened cardboard backing, a second drawing showed a winding blue line and an arrow pointing to a small square.

Beneath it, in Mara's handwriting, were five words:

THE ROOM IS NOT EMPTY.
