She said it without hesitation when Imogen brought her into the interview room, though the room had no fire and the fog had turned the window into a blank gray pane. Petra removed her gloves finger by finger and placed them beside her handbag.
“Not approximately,” Imogen said. “The exact time.”
“I looked at the clock in the hall before I went out.”
“Why?”
“Because Mr. Quill had kept me waiting.”
That was the sort of answer Petra gave when she wanted to sound truthful: specific enough to be checked, unimportant enough to seem natural.
Imogen set the municipal certificate on the table between them. “At 8:47, you were in Quill House. At 8:50, according to the medical examiner’s revised estimate, he could still have been alive.”
“I told you he was alive when I left.”
“Did he have the key ring?”
Petra’s eyes lowered to the certificate. “He put it in his coat during our argument.”
“You saw him do it.”
“Yes.”
“Did you see him take it out again?”
“No.”
“Did you see the coat after you left?”
“No.”
Imogen leaned back. The answer had been waiting for her. She could feel the shape of it: Petra had not removed the ring from beneath the desk, but she had been the last living person to see it. The waxed filament made the distinction less useful than it should have been. Whoever removed the ring had known its exact position. Petra had known the room. Petra had handled the keys. Petra had a reason to lie about the payment file.
And yet the conclusion sat too comfortably in the chair across from her.
“What did Quill say when you left?”
“That he would find the document himself.”
“Which document?”
“The one concerning Pell.”
“He sent you to retrieve a file that did not exist, then told you he would find it himself.”
“Mr. Quill enjoyed making people search for things.”
“Did he tell you to return the study key?”
Petra looked up. “No.”
“Did he ask you to move the desk?”
“No.”
Next
Imogen will search for Quill’s missing coat, which may connect the vanished key ring and weapon—or reveal that both absences were designed to survive her investigation.
There it was. Not a denial of the act, but a denial of the invitation. Petra had been expected to enter the room. She had been expected to open the drawer. She had not been expected to finish the arrangement.
Imogen took the brass ruler from her coat and laid it beside the certificate. “The ring was on the floor when it left its impression. The desk was moved after the ring was removed. The thread was caught at the edge of the impression. Someone pulled the ring away with a waxed filament, or used one while lifting it.”
Petra’s mouth tightened. “You think I did it.”
“I think you were there.”
“That is not the same thing.”
“No. It is worse.”
For the first time, Petra’s composure lost its faint amusement. She folded her gloves together.
“If I had killed Bartholomew,” she said, “why would I leave the key beneath the carpet for you to find?”
“Perhaps you wanted me to believe you had not.”
“Then why admit I handled the ring?”
“Perhaps because Quill had already arranged for me to discover that.”
The words seemed to surprise Petra. Not because they were false, Imogen thought, but because they had come too close to the room’s true architecture.
Petra turned her head toward the fogged window. “You have made him very clever.”
“He made himself clever.”
“He made a great many things. Money. Enemies. Paperwork.”
“Did he make his death?”
Petra’s gaze returned to her. “You are asking whether a dead man planned his own murder.”
“I am asking whether you believe every clue in that study was meant to be found.”
“No.”
“Which one was not?”
Petra considered. “The weapon.”
The answer landed without drama. That made it heavier.
“Why?”
“Because if Mr. Quill had wanted to tell you a story, he would have given you the weapon as well. He was never careless with an ending.”
Imogen watched her carefully. “Unless the weapon was meant to remain missing.”
“Then the story is not finished.”
“That is what you want me to think.”
“No,” Petra said. “That is what the room wants you to think.”
A constable knocked and opened the door. Ferro stood behind him, holding a sealed envelope from the municipal records office. His expression was grim in the way it became when facts arrived that could not be argued with.
“Calloway,” he said. “A word.”
She left Petra under the constable’s eye and followed him into the corridor. The station smelled of wet wool, coal smoke, and the sour coffee Ferro drank when he wanted to punish himself.
He broke the seal on the envelope. “The certified copy is admissible. Shaw found the original register and signed an affidavit. Quill paid Pell’s launch fee on the eighteenth, advanced him money for a private passenger, then settled the balance on the twentieth.”
“I know.”
“You know. I need to know what I can do with it.”
“You can establish that Quill was involved in Sera’s disappearance.”
“Can I establish that Sera had a reason to kill him?”
“She had a reason to hate him.”
“That is not what I asked.”
“No.”
Ferro opened the envelope wider and tapped the page. “This is outside his estate records. It survives him. It survives the missing file. If we put it before the magistrate, the defense can’t say we built the whole case out of Quill’s papers.”
“Nor can they say it proves murder.”
“Not murder by Quill.”
Imogen said nothing.
Ferro studied her face. “You’ve been given a clean motive, a prior conviction, stolen money, and a room only she could supposedly have staged. Now you’ve found a history between the victim and the accused that makes the motive uglier. What exactly are you waiting for?”
“The part that doesn’t fit.”
“Everything fits.”
“That’s the problem.”
He exhaled through his nose. “The prosecutor wants a recommendation by tomorrow.”
“She is not ready for a recommendation.”
“She was ready the day we found the body.”
“Then she was wrong.”
The chief’s expression hardened, but not with anger. With fatigue. “You asked for a second chance. This is what one looks like in Harbor Point. You take the evidence you have, or you spend another year explaining why a dead man’s house made you uncertain.”
He walked away before she could answer.
Imogen returned to the interview room. Petra was standing now, her handbag clasped in both hands.
“Where is the coat?” Imogen asked.
“What coat?”
“Quill’s. The one he wore when you left.”
“In his bedroom, I assume.”
“It is not.”
Petra’s face altered by a fraction.
“The staff searched the bedroom,” Imogen continued. “The wardrobe, the laundry, the cloakroom. The coat is missing.”
“Then perhaps he left the house after me.”
“With the ring?”
“If he had it.”
“And the weapon?”
Petra looked toward the closed door. “You think the coat contained that too?”
“I think a man who leaves behind a locked room, a missing key ring, and no weapon may have left behind the wrong absence.”
Petra’s voice lowered. “You said he was alive when I left.”
“You said that.”
“I saw him standing by the desk.”
“Did he look at you?”
“Yes.”
“Did he speak?”
“He told me to close the door.”
“Which door?”
“The study door.”
“Did you?”
“Yes.”
Imogen felt the case shift—not toward Petra, not toward Sera, but toward the interval after Petra’s departure. A living man had stood beside the desk. A door had closed. Somewhere between that moment and Sera’s discovery, the room had become a machine waiting for its witness.
“Why did you leave it unlocked?” Imogen asked.
Petra went still.
“I didn’t,” she said.
“Then how did Sera enter?”
“The bolt was thrown.”
“From outside.”
Petra’s eyes dropped to the brass ruler. “You already knew that.”
“I wanted to hear you say it.”
“And now you have.”
“No. Now I know you knew.”
Petra gathered her gloves. At the door, she paused.
“Detective,” she said, “if you keep following the evidence, you will eventually arrive at the person who wanted you to follow it.”
“Is that a warning?”
“It is an observation.”
After Petra left, Imogen stood alone in the room. On the table lay the municipal certificate, the one fact Quill could not have planted after his death. It gave her a history, a motive, and a reason to distrust the dead man’s papers.
It did not give her a murderer.
Before dawn, she would search for Quill’s missing coat. Before noon, Ferro would ask whether the independent record was enough to put Sera in the dock. And somewhere between those two demands, Imogen would have to decide whether proving Quill had lied was more important than proving Sera had not killed him.
The fog pressed against the station windows.
Inside it, the case waited with every door apparently locked.
