Senna left first, because Senna was the one who could.
She wrapped her shawl over the leather apron, told the brazier without looking at it to keep its temper, and gave Marek a short nod that meant go the other way and do not be tidy about it. Then she stopped at the curtain and looked at Isolde the way an old physician looks at a difficult prescription she is still weighing whether to sign.
"Seven hours," Senna said. "I'll come back through the south cellar with two pair of hands and a coat that fits. Until then he does not let go of you. You do not pull away."
"I understand."
"You don't yet. You will." She lifted the curtain. "Match his breath. Don't try to think about it. The thinking part is the part that broadcasts."
The curtain dropped. The room was three people and a brazier; it became two people and a brazier when Marek went a beat later through the arch by which they had come.
The tall man held still while their footsteps thinned out of the brick. He stayed at his own place near the curtain, hands open at his sides, and waited until the corridor outside had gone back to the silence it had owned before any of them touched it.
When he turned, he turned towards her, not at her. She had spent fifteen years registering differences in how people approached a desk, and the body that walked across the small chamber to her brought no requirement with it. Only a fact.
"It works like this." His voice was lower in the closed room than it had been in the tunnel. "Hand on your throat. Over the mark. Your back to my chest. No talking. We breathe. My out, yours out. My in, yours in. Two minutes to dim. Senna said seven hours."
She heard the words and translated them, automatically, into the register of a procedure: contact, duration, fall-back. The translation was the thing she had to do to be able to stand up off the stool.
She stood.
"Two minutes."
"To dim. To go dark, longer. To be sure we are not bright at the surface, hold for hours."
"All right."
"All right."
He waited. He did not approach. The waiting was deliberate, and she understood, sluggishly, that he was waiting for her to walk towards the wall, and that the walk was hers to choose.
She walked.
The chamber had a vault wall of brick laid in the same herringbone as the tunnel ceiling, and the bricks at shoulder height had been worn smoother than the rest by a century of bakers' apprentices leaning against them while their masters shouted. She put her forehead against the brick first, because the forehead was the part of her that had decided this was now her morning. Then she turned to bring her back to the wall, and then, because the geometry he had described required her facing the wall, she turned again and put her hands flat against the brick and lowered her shoulders.

He stepped in behind her.
The displaced air at the back of her neck reached her before he did. His right hand came forward over her shoulder, palm open, and laid itself against the side of her throat where the mark lay under the cloth.
The cloth was thin enough that his palm was on the silver through one layer of linen. She had not lowered her collar this time. He had not asked her to.
The first thing his palm was, was cold. The tunnel air had been on his hand longer than on hers. The cold lasted four heartbeats, and then his skin warmed to the temperature of the inside of his coat, and the silver under her collar took the new heat and lost a fraction of its own brightness.
She watched the light at her throat through the angle of her own shadow on the brick.
A pulse, and another, and a slower one after that.
His chest came to her back. Not pressed. Placed. His other hand stayed away from her, at his side. He did not put his arm around her. The contract had been the throat and the breath, and he kept to the contract.
His breath touched the small hairs at the side of her neck before she heard it.
She matched it.
The first match was a clumsy one, off by half a count, because she had been holding her own breath without noticing. The second was closer. The third was correct. The silver under his hand went from silver to a paler silver to a colorless gleam that lived only in the cloth now, gone from the skin underneath, and then the cloth went still.
Overhead, boots. Four of them, walking the brick street by counting. They had been there before, in the moment before Senna had said now would be the time. They had stayed. They had widened their loop.
The boots paused.
Her breath wanted to pause with them. His did not. His breath went out steadily through his nose at the back of her hair, and she felt the slight pull of him taking the next one, and her own went after his without permission from any of the parts of her that gave permissions.
The boots resumed. They moved north, and then further north, and then the ceiling stopped sending her boots.
She was standing in a chamber under a baker's oven with the back of her head against the chest of a man whose face she knew only from a wanted poster, and her body was not afraid.
That was the sentence her mind offered her, in the careful syntax of the Registry's quarterly summary report. The subject's body is not exhibiting fear-response indicators. She cataloged it and set it aside, because cataloging was the only available method of remaining a person.
His palm did not move on her throat. It rested there with the weight of an object that had been put down on a shelf where it belonged.
Time did the thing time did in archives. It went away and came back at intervals, and the intervals lengthened. She counted, for a while, because counting was what her shoes did on a stair and what her thumbs did on the edge of a page; counting was her hand-rail. She counted his breaths, and hers, and then stopped counting, having lost which breath she was on.
At some point her shoulders had lost the line they had been holding. They had come down. She had not given them permission.
Her forehead bent forward until it was near the brick again.
At some point her eyes closed.
The choice registered only afterward, against the dark inside her eyelids: her body had been waiting for permission to be tired for somewhat longer than a morning, and the permission had now been granted by an absence: the absence of the requirement to be Isolde Verren, Senior Archivist, second floor, north wing. The absence had a hand on her throat. The hand belonged to a man who had been a face in three drawings on a wanted bill, and the absence was not contradicted by him.
She thought, slowly, that she should be horrified. The thought arrived at the right address without its luggage.
A long time passed. The chamber's brazier ticked down to coals that gave the brick a russet warmth at the floor and nothing higher. The curtain across the corner did not move, because there was no draft to move it. Somewhere above them in the world, the bakers' afternoon was turning into the bakers' evening; the smell of yeast had thinned in the air. None of it broke the brick.
His breath, slow, even, the size and weight of a sleeping animal pressed against the back of her.
Hers, slow, even, the size and weight of a thing that had stopped being asked to perform.
For fifteen years of mornings she had done a column of small steady motions designed to make sure she did not, at any point, soften. Tea, exact measure. Collar, exact angle. Glasses set on the desk in the corner where the lamp would catch them. The discipline had not felt to her like a wall; it had felt like a hallway. Now the hallway was empty for the first time in fifteen years, and someone she had not been introduced to was standing inside her hallway with his palm on her throat, and her hallway did not mind.

The boots came back.
They were further away this time. They had widened their loop again. They paused at a corner she could not place, because her mental map of the bakers' quarter was a surveyor's plan and not an inhabited geography. The pause was longer than the first. The mark under his hand twitched and brightened, a quick small flare she felt before she saw, because the cloth at her throat warmed by half a degree before the silver showed at the edge of his fingers.
He tightened his hand.
Not hard. Closer. His thumb moved a half-inch to take the pulse point on the side of her neck, and his palm settled. Their breaths had separated by a heartbeat in the moment of the brightening. He brought his back to hers without speaking, and her own followed his into the shared rhythm with the lag of a person learning a dance.
The flare faded. The boots, after a long minute, resumed and went on. She tracked the sound out of the ceiling and did not let herself name the absence of it as relief, because relief was a luxury that asked the body to drop, and the body could not drop yet.
Against her hair, low, near a vibration in the bone behind her ear:
"Breathe. With me. Or they find us."
The voice was the voice that had given the dark the word move. It was the voice that had given her the word will you. It was something else here, something the tunnels had not made room for: a softness it did not seem to know it carried, and an opening in the vowels that belonged to the southern provinces, where the cities were built around fountains and the consonants gave way.
She had no professional reason to know the accent of the southern provinces. The Imperial Registry did notcatalog accents. The fragment of her that recognized how the voice opened around the e of breathe had not learned it at a desk.
Her chest understood before her mouth did. She breathed. With him. The mark stayed dark.
They held the chamber a long time after the second patrol passed. The coals settled. Somewhere above them in the world the bakers' evening turned into the bakers' empty hour, when the ovens cooled and the apprentices went home and the streets above the herringbone gave back to the cold its old ownership. None of it came through the brick.
When his hand moved at last, it moved by the smallest measure she could have registered. His thumb lifted off the pulse point. The palm stayed. The motion was the beginning of a sentence he had not yet decided whether to speak.
He spoke it.
"I'm sorry."
The word came out of him too fast. It had not waited for the next sentence to be ready. It sat in the chamber alone for the time it took for him to recognize what he had said, and then it sat there a beat longer, because he did not call it back.
She did not turn. She could not have turned without dislodging the hand, and the hand had become the thing the room was built around.
She heard him take a breath, not for the mark, for himself, and find the voice again.
"Seven hours," he said, evenly, the way a man recites a duty. "I will have to not let you go."
The brick was cool against her palms. The silver under his fingers was dark. The boots did not come back.
She closed her eyes again and let the word sorry sit in the room where he had left it, because there was nowhere to put it that would make it smaller.
