The Locksmith’s Book

The first locksmith on Ferro’s list had been dead for eleven years. The second had moved inland. The third, Harlan Dowe, kept a shop on Pilgrim Street beneath a sign so salt-eaten that only the word LOCKS remained legible.

Imogen found him filing a brass key at the back counter. He was a narrow man with a magnifying lens strapped over one eye, and he looked at her badge before he looked at her face.

“Quill,” he said.

It was not a question.

“You supplied his keys?”

“His father’s, first. Bartholomew inherited the habit of locking things that did not need locking.” Dowe set down the file. “What has he done now?”

“He’s dead.”

“That is generally what people mean when they say someone has done something.”

Imogen placed the estate inventory on the counter. “I’m looking for records of duplicates. The study door. The household cabinet. Any key associated with a room at the Trawl Street boarding house.”

At the last phrase, Dowe’s lens stopped moving.

“Room six?”

“You know it?”

“I know that Quill brought me a key stamped with a six three months ago. Said it had been found in a drawer and needed copying.”

Imogen kept her expression still. “Did you copy it?”

“No. The key was worn past use. I told him to take it to the boarding-house keeper and have the lock changed.”

“Why bring it to you?”

“Because he wanted to know whether it had been used recently.”

The answer was too exact, and Dowe seemed to hear it himself. He removed the lens and rubbed his eye.

“Did you tell him?”

“I told him the wards were polished. That could mean use, or a person polishing the key with a cloth. Quill asked whether a copy could be made without leaving a record.”

“And could it?”

“Not a proper one.” Dowe turned toward a shelf of ledgers. “A poor one, perhaps. Brass remembers being cut. Steel remembers better.”

He brought down a book bound in cracked green leather. The pages smelled of dust, oil, and the damp that got into everything in Harbor Point. Under a date three months before Quill’s death, Dowe found an entry in a cramped hand.

B. QUILL. STUDY KEY—DUPLICATE. TWO COPIES. ONE TO REMAIN BLANK-BOWED.

Imogen read it twice.

“Two copies?”

“His instruction.”

“What does blank-bowed mean?”

“No number, no mark, no maker’s stamp. A key without an identity.”

“Why would he want that?”

Dowe shrugged. “People ask for strange things when they mean to give keys away.”

Imogen looked at the line again. The study key recovered beneath the desk had a smooth bow, worn but unmarked. It had not been a duplicate made for convenience. It had been made to pass for an old key.

“Where is the other copy?”

“Quill collected both.”

“Are you certain?”

“I have a receipt.”

The receipt was pinned beneath the ledger page. Quill’s signature ran along the bottom in a firm, unhurried hand. Imogen knew the signature from the will, the memorandum, and the labels on the evidence bags. The same hand that had written Sera’s name as if it were an entry in an account book.

She folded the receipt into an evidence sleeve.

“Did he order any other work?”

Dowe’s mouth tightened. “The study duplicates were not the only thing.”

He turned three pages forward. A second entry had been written in red pencil.

ONE SMALL KEY RING. RE-BOWED. FOUR KEYS. CLIENT TO SUPPLY LABEL.

No date. No name.

“Is this Quill?” Imogen asked.

“Most likely.”

“Most likely isn’t useful.”

“Then it isn’t Quill.”

She leaned over the counter. “You remember him bringing a ring?”

“I remember the ring.”

“How?”

“It was ugly. Iron, not brass. Four keys, each with a different bow. One had a strip of blue thread tied through it.”

Imogen thought of the missing key ring in the inventory, the Pell key, the study key placed under the desk. “Did you re-bow it?”

“No. He changed his mind.”

“Why?”

“He asked whether I could make a key appear old without making it useless. I said yes. Then he asked whether a person examining it would know it had been altered.”

“And what did you say?”

“That depended on the person.”

Dowe’s eyes rested on her badge.

“On the person examining it,” he repeated.

Outside, a cart rolled over the wet stones. The sound faded into the fog.

“Did Quill leave the ring here?”

“No. He took it away.”

“Then why is the work recorded?”

“Because I wrote it down.” Dowe tapped the ledger. “I write down everything. That is why people stop coming to me.”

Imogen left with copies of the entries and a new understanding of the missing ring. It had not simply vanished from the study. It had been handled by a man who had considered its appearance, its age, and the impression it might leave in another person’s hand.

At Quill House, Sera was in the corridor outside the schoolroom, sorting linen. She glanced at the papers in Imogen’s hand and did not ask what they were.

“You found the locksmith,” she said.

“He remembers Quill ordering two duplicate study keys.”

Sera folded a sheet with unnecessary care. “Did he remember me?”

“No.”

“That would have made it easier.”

“It would have made it cleaner.”

Sera’s hands stopped. “Clean is what he wanted.”

Imogen watched her. “You’ve said that before.”

“I’ve been saying it since the first day.”

“You knew about the cord. You knew the study bolt could be drawn from outside. You took a page from his desk and a key from his schoolroom. You were in this house every day.”

Sera met her eyes. “And you think I’m about to make your work easier by confessing.”

“I think you’ve left something out.”

For a moment the corridor held only the distant knock of a pipe.

Then Sera placed the linen aside.

“Two nights before he died, Quill moved the spool.”

“From the schoolroom?”

“To the study.”

“Why did you notice?”

“Because he made me fetch it.”

Imogen felt the familiar tightening behind her ribs. “What did he say?”

“He said the drawer in the schoolroom was sticking. He wanted the black cord brought to him. I took it upstairs.”

“And you didn’t mention this.”

“I didn’t mention the cord at all.”

“Why?”

Sera gave a small, humorless smile. “You have already explained why.”

The answer was fair. It was also dangerous. If the cord had been moved into the study before the murder, Sera could have known exactly where it was. She could have handled it. She could have used it. The truth had not freed her from the mechanism; it had given the mechanism another place to fasten.

“Did you see the keys?” Imogen asked.

Sera looked toward the closed schoolroom door.

“Quill wore them on a ring. The night before he died, he left them on the hall table.”

“The missing ring?”

“I don’t know. There were four keys.”

“Did you touch them?”

“No.”

“Did anyone else?”

Sera’s gaze shifted to the staircase. “Petra Vance came to the house that afternoon.”

“Why?”

“She and Quill argued in the study. I couldn’t hear the words. I heard the ring strike the desk.”

That detail was small enough to be true and shaped enough to be useful. Imogen could almost see the room: the ring laid down, the keys separated, the duplicate prepared to imitate the original. But seeing a sequence was not proving its author. It was only proving that the sequence had been made visible.

“Why didn’t you tell me this yesterday?”

“Because you were looking at me as if every fact had a price.”

“It does.”

“Yes.” Sera picked up the linen again. “That is why I kept some.”

Imogen should have been angry. Instead, she heard the exhausted logic of it. Quill had built a case from Sera’s silence, and every honest answer she gave arrived with its own shadow.

She returned to the station before dusk and placed Dowe’s ledger copies beside the locked-room report. Then she added Sera’s statement, word for word, including the parts that made her look worse.

Ferro read the pages standing up.

“This puts her hands near the cord,” he said.

“It puts Quill’s hands near the duplicate keys.”

“It puts her near both.”

“Yes.”

He looked at her. “You’re still going to submit it?”

Imogen thought of the smooth blank bow, the ring altered but never collected, the cord moved into the room where it would later close the door. She thought of how easily she had followed each invitation.

“Everything,” she said. “The clean evidence and the dirty evidence.”

Ferro sighed. “That won’t save her.”

“No.” Imogen sealed the statement. “But hiding it won’t save anyone.”

On the envelope she wrote: DUPLICATE KEYS—QUILL COMMISSION. Then, beneath it, she added: SERA LINDQVIST—SUPPLEMENTAL STATEMENT.

The two lines sat side by side, equal in ink and unequal in consequence.

Somewhere, the missing key ring was still waiting to be found. When it surfaced, Imogen knew, it would not answer whether Sera had touched it.

It would answer whether someone had wanted her to seem as though she had.
