Lord Erich von Hals opened his own side door at the seventh evening bell.
Dayla recorded the time before crossing the threshold.
The choice of hour was part of the meeting. Government clerks had left their offices. Noble households had begun receiving dinner guests. A consultant, his secretary, and a southern lord could all be absent from their usual places without requiring a shared explanation. By the time the capital noticed anything unusual, their absence would belong to yesterday.
Von Hals looked first at Frederick, then at Dayla's case of papers.
"No servants in the rear rooms," he said. "Your coats may remain with you."
He led them through a receiving hall arranged to communicate old money, reliable taste, and nothing personal. The candles were fresh. The portraits had been selected for ancestry rather than affection. A dining room visible through an open arch contained twelve places though Von Hals lived alone.
The study at the rear of the house abandoned the performance. Four chairs. A low table. A coal fire. No display shelves and no desk from which one man could preside. The room was designed for decisions that needed no witness except the people making them.
Lord Kaspar von Drent was already seated.
He inclined his head to Frederick. His eyes paused on Dayla long enough to confirm that the same instrument from Drentmark had been brought into the capital.
Dayla took the chair nearest the wall and opened her notebook. The first page already held the date, location, attendees, and purpose written in a hand small enough to waste no paper. The purpose line read: Continuity Consultation, Capital District.
It was not false. It was insufficient by design.
Frederick sat opposite Von Hals. "Thank you for receiving us."
"Kaspar has described the southern arrangements," Von Hals said. "My staff have also completed the personnel lists you requested. I have accepted the preliminary work. I have not accepted a use for it."
"That is why we are here."
Frederick laid out the architecture without naming it revolution. The king and loyal lords would assemble in the great hall for the consultation authorized by the senate. The senate expected to define the transition afterward. It believed the right to name a future office included the right to control the man who occupied it.
That assumption had been the hinge of Frederick's proposal. He had allowed seven men to believe they were building a chair when they were authorizing the removal of the room around it.
"At the sixth bell on consultation day, the palace hall closes," Frederick said. "No messenger enters or leaves until the announcement is complete. Within the same hour, the senate building must cease to function as an institution."
Von Hals did not ask what cease to function meant.
"My district controls its outer watch," he said. "The senate appoints its own inner guard."
"Your personnel list identifies nine of those guards with debt, three with family appointments controlled by your office, and two who will be away that week under orders already prepared by their captain."
Von Hals's gaze shifted to Dayla's case.
She had drafted those orders. The captain would sign them believing he was balancing rotations before a crowded session. Every sentence in the documents was ordinary. Together they made the building permeable.
"Twelve men inside," Von Hals said. "Six at the doors."
"If that is the number your method requires."
"You have no method?"
"I have a parameter. The building cannot reopen as the seat of a rival authority. The senators cannot be available to summon supporters, testify against the new arrangement, or claim continuity. How you satisfy the parameter belongs to the district lord who knows the building."
Dayla wrote the sentence exactly.
Frederick divided responsibility with the same precision he used to divide grain routes. He did not tell a man how to kill. He created a condition in which killing became the remaining method and allowed the man nearest the work to name it.
Von Hals rested two fingers against his lower lip.
"The chamber draws air through a single shaft below the eastern roofline," he said. "The inner doors can be barred from the corridor during a security alarm. We use smoke. A slow fire in the shaft first, then the records room after the chamber has gone quiet. The senators lose consciousness before they understand the exits are closed. When the visible fire begins, my district watch responds. They fail to enter in time."
"How many people outside the chamber?" Frederick asked.
"Two clerks until the fifth bell. A porter. Four inner guards after rotation."
"The clerks leave on schedule," Frederick said. "The porter is reassigned to the west entrance for a delivery inspection. The four guards?"
"My men replace them during the alarm."
"No unnecessary deaths."
Von Hals turned to Dayla. "The porter order must come from the district maintenance office, not mine. If my seal moves him on the same day my watch fails to open the chamber, even an incompetent inquiry will join the two."
Dayla reviewed the prepared chain in her mind. "The office can receive a complaint about water damage at the west archive. The porter has the only complete key ring. His supervisor will reassign him without a seal above the office level."
"Who submits the complaint?" Kaspar asked.
"A copying clerk whose roof actually leaks. He submitted the same complaint last spring. We return the old form to his desk and let him believe it was never filed."
Von Hals studied her. "You have the form?"
"A copy. The original remains in the archive."
Frederick said nothing. Dayla recognized the silence as approval and hated that she recognized it.
Von Hals examined him. "The senators are necessary."
"Under the parameter, yes. The staff are not."
Dayla's pen continued moving.
She had walked through the senate building that morning. A junior clerk had apologized because one corridor smelled of wet plaster. He had held two doors for her while carrying a stack of copied budgets against his chest. Dayla had thanked him and asked how many employees remained after the fifth bell.
He had answered proudly. She had written the number in the margin.
Now his early departure existed as one line in the plan. The fact that she had helped spare him did not alter the fact that she had counted him for a fire.
"How long?" Kaspar asked.
"From closure to unconsciousness, less than a quarter hour," Von Hals said. "From ignition to a fire large enough to explain the bodies, perhaps forty minutes."
"The hall announcement will still be underway."
"Then the two events acquire the same official hour," Dayla said.
The three men looked at her.
She had not intended to speak. Yet the record mattered. If the senate died before the new authority was announced, Frederick could be accused of seizing power through murder. If it died afterward, surviving loyalists could argue that it remained a lawful rival for part of the transition. The same hour made sequence difficult to prove.
Frederick nodded once. "Correct. The public record must not establish which institution ended first."
Dayla added the instruction beneath the time.
Kaspar leaned back. "And the seven families?"
Frederick turned to him.
"Wives, children, adult sons," Kaspar continued. "The estates can finance opposition. The sons can call themselves heirs to murdered offices. If you remove the men and preserve their houses, you preserve seven centers of grievance."
"The senate seats are not hereditary," Frederick said.
"Grievance is."
"Nothing happens to the families. Their property remains theirs. Their accounts remain open. They receive the compensation owed to officials who die in service."
Von Hals watched Frederick more closely than before. "That is a vulnerability."
"It is a limit."
"Limits become vulnerabilities when enemies do not share them."
"Then we will manage the vulnerability."
Kaspar's expression did not change. "You are asking us to risk the entire arrangement for people who will hate us."
"No. I am refusing to enlarge the arrangement for convenience. Their deaths serve no present requirement. If one later commits an act against the state, that act will be answered. We do not punish a household in advance for understanding what was done to it."
The sentence was colder than mercy. It protected the families because Frederick had not placed them inside the calculation, not because he felt their grief. Dayla found the distinction more trustworthy than kindness would have been. Kindness changed with mood. A boundary stated as procedure might survive him.
She wrote: Estates and dependents excluded from action. Frederick reviewed the line over her shoulder and added, "Write expressly protected. Excluded can be revised by omission."
Dayla struck the phrase once and replaced it.
Expressly protected.
The words looked fragile in the notebook. They were still more than the families had possessed before he spoke.
The rest of the meeting concerned routes and signals. Von Hals's men would enter as maintenance workers over two mornings rather than arrive together. Kaspar's southern riders would wait outside the capital district to intercept any senator absent from the session. A sealed dispatch from the palace would trigger both closures. Dayla assigned each copy a mark that identified its route without naming its purpose.
By the eighth bell, the plan occupied six pages.
Frederick read them in silence. He corrected one time, removed an adjective from the alarm instruction, and drew a line through the sentence identifying Kaspar's riders. Their destination belonged in a separate order so no single document connected the senate building to the southern roads.
"Prepare three clean copies," he said. "One for Von Hals. One for Kaspar. One retained without names. The working notes remain with you."
Dayla closed the notebook.
The men stood and clasped hands. Kaspar first, because the south supplied force. Von Hals second, because the capital supplied access. Frederick last, because the design required him to appear at neither site.
Outside, the avenue of lords had entered its social hour. Carriages stopped beneath lit windows. Music escaped from a house across the street each time its doors opened. A couple walked past Dayla and Frederick arm in arm, speaking about a dinner neither would remember in a week.
Frederick matched Dayla's pace rather than walking ahead.
After one street he said, "You have not opened the notebook."
"The meeting is concluded."
"You write after meetings."
"Usually."
They continued another ten paces.
Dayla stopped beneath an unlit balcony. "Will the families be protected when it becomes inconvenient?"
Frederick stopped too.
"Yes."
"Von Hals and Kaspar both believe the decision is a mistake."
"They are permitted to believe it. They are not permitted to alter it."
"That is not what I asked."
His face remained still, but stillness in Frederick was not emptiness. Dayla had spent four years distinguishing calculation from restraint. She could not identify which one held him now.
"I do not lie to you," he said. "The protection is not a word used to complete the negotiation. It is an order. If either man breaches it, I will treat that breach as disobedience against the structure we are creating."
"Even after you need them?"
"Especially then. A limit observed only while convenient is not a limit."
Dayla believed him.
The belief brought no comfort. Seven men would still enter a chamber and breathe smoke until the state no longer had to argue with them. Frederick had not become merciful because he refused to kill their children. He had merely drawn a boundary around his violence and promised to defend the shape.
Yet boundaries mattered. Dayla knew that because every order she drafted was made of them.
They resumed walking.
"You spoke in the meeting," Frederick said.
"The timing required clarification."
"It did."
She waited for correction. None came.
"Your sentence prevented a sequence from entering the public record," he continued. "Keep that principle in the clean copies."
He had praised neither her judgment nor her nerve. He had accepted the contribution and converted it into procedure. From Frederick, that was the more dangerous recognition.
Dayla looked at the case in her hand. Inside it were six pages that could end a senate. Tomorrow she would rewrite them without hesitation marks, ash from Von Hals's fire, or the pressure of Kaspar's question. The clean copies would look as ordinary as every document that had prepared the road toward this room.
She wondered when accuracy had ceased to be a record of the work and become one of its weapons.
At the next intersection, Frederick turned toward the consultancy house. Dayla followed, carrying the notebook against her side.
Behind them, Lord Erich von Hals remained in his plain study, deciding how little smoke would be enough.
