By morning, the seventh door had become respectable.

It had acquired a lintel, though Iona had not slept long enough for anyone to install one. Its paint had dried into an old civic blue used on municipal broom closets before the current administration decided blue encouraged introspection. A brass plate appeared at eye level:

TEMPORARY STORAGE

AUTHORIZED PERSONNEL ONLY

The plate was almost persuasive. That was what frightened Iona most. A lie in Latch did not need to convince everyone. It only needed enough people to behave as though it were inconvenient to object.

Mirela sat at the kitchen table with a blanket around her shoulders and a wrench in one hand. The wrench was older than Iona, black-handled, nicked from years inside the Clock House. She had slept beside it.

"It is not temporary storage," Iona said.

"No."

"It is using the city's habits."

"All clever doors do."

Iona set tea before her mother. "How much did Rowan tell you before he left?"

Mirela looked at the steam rising from the cup. It wrote nothing. "He told me enough to prove he was my son and not enough to prove he was wise."

"That is not an answer."

"It is a category of answer."

The first bell rang again at eight. This time it sounded correct, which made the previous morning worse. A mistake repeated is an incident. A mistake denied is architecture.

Iona took the tram to the Bureau with Rowan's message copied in her notebook. She did not write the words "First Door." She wrote "primary threshold," then crossed it out, then wrote "family matter." That looked pathetic enough to be safe.

At the Bureau, everyone was cheerful in a rehearsed way. A banner hung above the permit counters:

THANK YOU FOR SUPPORTING THE SCHEDULED ACOUSTIC VARIANCE.

Two clerks were arguing about whether the celebration bun should be classified as edible propaganda or commemorative pastry. Deputy Registrar Pell's office door stood open, which meant he wanted to be overheard.

"Surveyor Vell," he called.

Iona stepped inside. Pell was shaped like a man assembled from straight lines and caution. His desk held no papers except the one he was reading, and his pens lay in a row like accused parties.

"Your amendment work was prompt," he said.

"Thank you."

"Promptness is a form of loyalty."

"I thought it was a form of scheduling."

His eyes lifted. Iona regretted the sentence immediately.

Pell tapped the paper. "A minor anomaly was reported near your residence last night."

Iona kept her face still. "Was it?"

"You live above the former umbrella shop on Tallow Street."

"Yes."

"A neighbor reported condensation spelling an alarming phrase on the outside wall."

"Condensation is prone to drama."

Pell smiled without improving the room. "You are a capable surveyor, Iona. Capable people sometimes feel invited by irregularity. It flatters them. They believe the city has chosen them for a special errand."

"Has it?"

"No. The city has departments for errands."

He slid the paper toward her. It was a voluntary disclosure form, already filled out except for her signature. It described a harmless vapor event caused by kettle misuse.

Iona read the form. "This says I own a kettle with speculative tendencies."

"Do you not?"

"Our kettle is loyal."

"Then sign on its behalf."

She took the pen. The nib hovered.

Behind Pell, through the frosted window, the Clock House blurred and sharpened. For one instant its twelve faces showed twelve different times. Then the glass clouded.

Iona put the pen down. "I need to consult the archive before I sign. If this is a classified vapor category, I should use the correct number."

Pell considered her. "Half an hour."

"The archive clerks require forty minutes to locate their own chairs."

"Thirty-five."

The Bureau archive occupied three underground floors and one rumored mezzanine that was officially a metaphor. Iona's pass admitted her to standard door histories, hinge taxation, and the section on fraudulent alcoves. It did not admit her to extinct thresholds, unlicensed borrowings, or anything marked FIRST.

She went instead to the correction shelves.

Whenever Latch edited a record, the original was supposed to be pulped, blessed, and stirred into pavement paste. In practice, clerks were sentimental. They kept copies behind loose skirting boards, inside hollow ledgers, under chair cushions. Iona had discovered half the hiding places during her apprenticeship and reported none of them, because a city without old mistakes is only pretending to have learned.

She found yesterday's witness slips in a ledger labeled Seasonal Drainage Disputes. They had been altered. Not with ink. With reality.

The old sentences shimmered beneath the new:

The first bell sounded wrong.

Underneath, faint as a thought:

The first bell sounded toward somewhere else.

Iona copied the phrase.

At the back of the ledger, one slip had not been amended. It came from an address that no longer existed.

12 Ash Step, Lower Latch.

There were eleven Ash Steps. Iona knew because Rowan had once broken his wrist jumping from the ninth to the tenth on a dare. The slip's witness name was blurred except for an initial: R.

The report read:

The bell answered. I answered back. The door counted me.

A sound came from the next aisle: paper breathing.

Iona slid the ledger back and crouched. Through a gap in the shelves she saw a woman in the charcoal uniform of the Office of Cancellations. No, not a woman exactly. A clerk so precise she seemed drawn with a ruler. Her hair was white, her gloves black, her badge a silver zero.

The Auditor.

Every child in Latch heard stories of the Office. It collected unpaid tolls, closed unlawful passages, and canceled places that could not justify themselves. Most of its clerks were ordinary, tired, fond of stamps. Auditors were different. They arrived when an inconsistency had learned to run.

Deputy Registrar Pell walked beside her.

"The Vell girl?" the Auditor asked.

"Manageable."

"No one with a borrowed door in her kitchen is manageable."

Pell's shoes stopped. "You know about that?"

"The door filed a complaint."

Iona pressed her palm to her mouth.

"It complains that it has been mislabeled," the Auditor said. "Temporary storage. An insult. It claims descent from an older authority."

"The First?"

"Do not be theatrical in an archive."

Pell lowered his voice. "If Rowan Vell is involved..."

"Rowan Vell was canceled."

The words moved through Iona like cold water.

The Auditor continued, "Yet his debt remains active. Debt without debtor. Door without license. Bell without self. These are related uglinesses."

Iona backed away. Her shoulder struck a shelf. A bundle of old permits slid loose and slapped the floor.

The Auditor turned.

Iona ran.

She knew the archive better than her fear did. Left at Drainage, right at Fraudulent Alcoves, down the staff stair where the third step complained, through a rolling rack of obsolete hinge prayers. Behind her, Pell shouted for security. The Auditor did not shout. That was worse.

Iona burst into the public hall, signed herself out under the name of a retired chimney assessor, and reached the street shaking.

At home, the seventh door stood open an inch.

Mirela sat beside it, pale but upright. "It knocked."

"Doors knock from the other side."

"This one is ambitious."

Iona showed her the copied slip.

Mirela read it and closed her eyes. "Ash Step."

"There are eleven."

"Now."

"What happened to the twelfth?"

The door exhaled steam across the kitchen floor. This time the letters formed slowly, each one dragged from effort.

NOON KEEPS WHAT LATCH ERASES.

ASK MAER TOLLIVER.

The last line took longest:

IO, I AM NOT DEAD ENOUGH.

Iona folded the paper until it fit in her fist.

Outside, the bells rang noon though the sky still showed morning.
