It was a quiet morning, and she should have known better than to trust it.

The eleventh day of the cycle came in grey and soft, with a mist lying low across the Low Sea and the tower rising out of it like something half-remembered. There was no wind. The bells sounded muffled and far away. Suzu woke before the first one, as she always did, and lay for a while looking at the ceiling, and then rose and washed and ate the bread and cheese that had appeared outside her door, still warm, with a slip of paper under the plate that said only: Sleep is not an optional resource.

She had folded the slip in four and put it in the inventory book, between the pages where she kept the list of her friends. It was not for any reason. It was simply tidy.

The party had the morning to itself. Miyu and Haruto had gone to the customs house, to wrestle with a stubborn coil. Ren and Nana were walking the quay to read the water gauge. Sael had left before dawn, with a courier's satchel over one shoulder and a look of faint distraction, and had said only that he would return by the third bell. She had the tower to herself, and the small dry room, and the blank white hours.

It was a dangerous thing, to give Suzu Arimura a blank hour.

She sat down at the table with the book and the stylus, and told herself she was going to organize.

---

The first hour was a good one. She copied out the full record of the gate: the windows, the interval progression, the revised figure from Miyu's meter. She redrew the diagram of the tower's levels, the flooded stairwell, the four dry landings, the private rooms. She recorded the market in its entirety, the prices, the rope-bound stalls, the names of the merchants, the tea. She wrote a page on Ren, and one on Nana, and one on Haruto, and a long careful paragraph on Miyu that began with her coils and ended with the little brass cog she kept touching at her collar. She was in the clear, quiet, orderly state in which a thing is understood only once it has been written.

When she had finished with her friends, she turned to a fresh page and wrote, at the top: Guardian.

She looked at the word.

It was a reasonable heading. It was a negotiation file. If she were to be under the supervision of one person for the better part of a year, it was only sensible to know the person's habits. Any competent representative would do the same. She had done the same with the vice principal, in her second year, and with the head of the student council, and with the very frightening man at the ward office who had approved the club's budget. There was nothing in it. It was background.

She wrote:

Sael Dunmarrow. Auditor, third rank. Keeps to procedure. Always accurate. Does not exaggerate. Will tell me what he cannot tell me.

That was good. That was neutral. She went on.

Prefers to be called Sael, not Auditor (corrected me on day one; has since stopped correcting me).

She paused. It was true. She had not noticed when it had begun.

Does not like his work called inefficient. Does not like being thanked for requisitions.

That was also true. She had thanked him, three days ago, for a loaf of bread, and he had gone as still as a pond and said, "It is a provision." She smiled at the page, and corrected the smile, and kept writing.

Taps two fingers on the nearest surface when concentrating. Left hand. Stops when he notices.

Grips fabric with his left hand when anxious. Right hand stays still.

Stands up straighter when he lies.

She looked at that last line. She had written it before, and crossed it out. She wrote it again, and this time she did not cross it out.

Tea: warm, not hot. Salt, no honey. Drinks it with his eyes closed, the first sip. (Does not know.)

The stylus was moving quickly now. She did not seem to be holding it. The sentences came one after another, very small, very tidy, and she was not quite sure where they were coming from. Lids: moves when surprised. Moves slowly when he is moved. Stays across when he is, something. Mouth: left corner, when amused. Duration, 0.8 seconds. Observed three times. Four, counting the market.

Her hand stopped.

It stopped in the middle of the word market, with the tail of the last letter half-drawn. It simply hung there above the page, as though a string had been pulled, while her eyes drifted slowly away from the ink and out through the shutters to the sea. She was not looking at anything. She was looking at a place on the plank where a boy had bumped her, and a hand had caught her arm, and a heart had hammered once against her palm like a trapped bird.

She did not know how long she sat there.

It was the knock that brought her back. It was not loud. It was two light raps on the open door, quiet as a falling leaf, and she did not hear them. She did not hear the door itself ease inward on its hinges, or the low step across the threshold, or the stillness that fell when it stopped.

"Arimura," said Sael.

---

She lifted her head.

He was standing three paces from her chair, with the courier's satchel in his hand and the morning mist still clinging to the shoulders of his coat. He had come back early. He had knocked, she realized later; she would learn, much later, that he had knocked twice, and that the door had been ajar, and that he had spoken her name three times before she turned. He had a folded paper in his other hand. He was holding it out.

He was not looking at her.

He was looking at the table.

The book lay open between them, a hand's breadth from his sleeve. It lay facing him. It lay with the page upturned, and the heading Guardian, and the small close writing running down the page in even rows, Taps two fingers, grips fabric, stands up straighter, tea with his eyes closed, left corner, 0.8 seconds. It was perhaps nine inches from his face.

She understood three things at once. The first was that he could read it. The second was that he could read it faster than anyone she had ever met. The third was that he had already done so.

It took him, she thought afterward, about one second. His eyes moved down the page the way a thumb runs down a column of figures, and he did not need to move his head. She saw the pupils contract, and then widen, and then the clear inner lid slide across them, and stop.

She slammed the book shut.

It made a loud flat clap. The stylus rolled across the table. She was on her feet without any memory of standing, with the book held against her chest in both hands like a shield, and her face on fire from the collar to the roots of her hair.

"That," she said. Her voice came out crisp and pleasant and entirely steady. It was a miracle. It was the voice she used to chair meetings. "That is a set of working notes. For the negotiation of the guardianship terms. It's standard practice to prepare a profile of the counterparty."

"I see," said Sael.

"It's strictly for the purposes of the arrangement."

"Yes."

"It has no other function."

"Of course."

"It doesn't contain anything that, that bears on, it's not personal."

"No," said Sael. "It is observational."

"Exactly. It's observational."

"It is also," he said, "accurate."

The silence went on for a long moment.

She had no procedure for it. She could feel the whole of her carefully built apparatus, the clauses and the headings and the neat transitions, folding in on itself like a house of cards. She said, rather faintly, "I didn't mean for you to see it."

"I am aware."

"I'm sorry."

"There is nothing to be sorry for. The door was open. I entered without waiting for a reply. The fault is mine." He spoke slowly, evenly, each word set down as carefully as a stone on a causeway. "I came to deliver a notice from the Senior Auditor. I will leave it on the table."

He put the paper down. His hand, she saw, was not quite steady. He drew it back and tucked it behind him, and lifted his gaze at last to her face, and his eyes were very dark and level and wide.

"May I ask a question," said Sael.

"Yes."

"Is there an error margin?"

She stared at him. "In what?"

"In the observations. You have recorded the duration of an expression as 0.8 seconds. I would like to know whether you consider the measurement to be reliable." He paused. "It is a technical inquiry. I am interested in your method."

She understood, in a slow cold wave, that this was a trap. It was a kind and terrible one, set without malice. If she said yes, it meant she was unsure of the measurement, and the measurement was a measurement of him. If she said no, it meant she had been sure.

She had never told a lie that was not also a kindness. She was a poor liar. She straightened her spine.

"No," said Suzu. "There isn't one."

The clear lid slid across his eyes. It moved very slowly. It went all the way across, and it stayed there, and in the half-second before it drew back she saw something in his face that she had not seen before and would not be able to name for a long time: a startled, unguarded, painful sort of tenderness, as though he had been given something he did not know how to hold.

"Thank you," said Sael, "for the clarification."

Then he turned and walked out of the room, and closed the door behind him, very softly, all the way.

---

She stood there for some time with the book against her chest.

Then she did the thing she had always done, in every crisis since the age of twelve. She made a plan. She told herself, in short sharp sentences, what had happened and what it meant. He had read the page. It was a page of notes. It was a negotiation file. It was nothing. She would behave as normal and he would behave as normal and the matter would be closed. She would not refer to it. She would not explain it. She would add no more entries, or if she did, she would add them in a section clearly labelled for the purpose.

It did not help. Her pulse would not slow down.

She went out to the balcony, because it was the only place in the tower that had air, and stood with both hands on the stone rail and her head down. The mist had begun to lift. The sea lay out before her in long, pale folds. In the distance, a pair of white birds turned and turned above the water, their wings gone gold, and she watched them without seeing.

It was only a task, she told herself.

That was the heart of it. It was a duty. She was the leader of the party and her friends were counting on her, and she had a guardian who held every one of their fates in his careful, exact, beautiful hands, and she had been studying him because she had to. She had been studying him because it was necessary. It was the same as the others. It was the same as everything she had ever done.

Except that it was not.

She had not written Ren's laugh into the page about Ren. She had not recorded the exact quality of the light on Haruto's face when he was happy. She had not noticed, in any note about Miyu, the way she held her breath before a good idea. She had written the things that were useful. But she had written down the first sip of tea, and the corner of a mouth, and the speed of a heart, and none of it was useful, none of it was for the party, and every line of it had come from somewhere low and warm and wholly unauthorized.

And under that was the older thing, the cold thing, the one that had lived beneath her ribs since she was twelve years old.

A field. A rope bridge. A girl's voice calling her name from the wrong side of the trees.

If you want something, said the cold thing, someone pays.

She had learned that lesson properly, and at an early age. She had wanted to be good at something, to be the sort of person who could make a day go right, and she had made the plan, and she had been so proud of it, and then a friend had fallen. It had been a small thing. A loose stone. A single detail she had not checked. But it had taught her the whole of the law, and the law was this: attention is a resource. Love is attention. If you love someone with half your mind, you will miss something with the other half, and someone will be hurt.

And the only one in the world who could not afford to be hurt, here, in a drowned country with a closing gate, was the whole of her party.

She had four friends to take home. She had no room for a fifth thing. She had no room for a look that lasted too long.

"It's a task," she said aloud, to the sea. It sounded thin. She said it again. "It's only a task."

The birds wheeled away over the water and were gone.

---

She did not go back to the room until late afternoon. When she did, the paper was lying on the table where he had left it, folded in thirds. She read it standing up.

It was a very short notice, on the Office's cream-colored stuff, in a hand she did not know. It was brief and courteous and exact, and it said that the Senior Auditor of the district would be returning to Ninth Tower on the morning of the fourteenth day of the cycle, for the purposes of a formal review of the party's registration. The ward would be required to present her effects. The ward would be required to be seated, and prepared, and in good order. It was signed with a flourish: a single long upward stroke, like the tail of a bird.

She read it a second time. She read the line about the effects.

Something turned over, slowly, in the pit of her stomach.

She thought of an old man's long finger, running down a margin, and stopping.

And she thought, with a small hollow jolt, that she had never in her life been so grateful for the existence of a clause: that a ward's record is not to be removed before the term is concluded. It was a very small and obscure sort of mercy. He had made it up on the spot, standing in the hall with his chin lifted. He had said it in front of the man who had raised him. He had lied for a page of notes in the margin of a book, and now she was holding a book that had a new page in it.

It had his name at the top.

She went to the table, and opened the inventory book, and turned to the final page. She did not read it. She only looked at the shape of the writing, the neat small rows. Then she took up the stylus and, with great care, with a hand that was not entirely steady, she wrote one last line at the bottom.

This is only a task.

She underlined it twice.

Her eyes were stinging. She told herself it was the dust.

The bell rang for the fifth hour, and the light came slanting in, and from far down the stair she heard a step: slow, even, a little too careful. It paused at the landing. It stood there for a long time, outside the range of her door, outside the reach of the lamp, and did not come up. She stood very still in the middle of the floor and listened to it not come.

At last it went away again, down and down, toward the water.

She did not move until the sound had gone. She was not sure whether she had wanted it to stay.
