He woke before the bell, as he had every morning for nine years, and lay with his eyes closed and took inventory.

It was the first thing a Warden learned and the last thing he stopped doing. Feet: cold, present. Knees: stiff, as stone floors had made them. Breath: shallow and high, the habit of a man who had discovered that a deep breath woke things in the chest. Then, last, and with the dread of someone opening a letter whose handwriting he already knew, the left arm.

He did not move it. He felt for it, the way you feel in the dark for a stair that may or may not be there. The wrist was cold. The forearm was cold and tight, as if the skin had been dried on a frame. And above the elbow, where there should have been only the ordinary ache of a limb slept on, ran a thin bright wire of pain that had not been there when he lay down.

Karn Reach, he thought. In the night.

He sat up. He pushed back the sleeve of his nightshirt and looked.

He kept a mark. It was a single stitch of red thread, sewn into the inside of the left cuff of every shirt he owned, a hand's breadth below the elbow. It was a childish thing, a private thing, and it was the only way he had found to tell himself the truth without having to say it aloud. For eleven days the black line had stayed below that thread. For eleven days, ever since a woman with ink-stained hands had laid a strip of tissue as fine as breath along the Sennet page, he had woken each morning and found the stitch alone in a field of pale skin, like a small red flag on a field that had been won back.

The line had crossed it. It lay a finger's breadth above, branching, fine as a hair, with the edges of it dry and grey and faintly lifted. He looked at it for a long moment, with no expression at all. He had learned the trick of that years ago. A face that does not move cannot be read, and the only person in the tower who might have read it was himself.

"A finger," he said, aloud, to the cold air. "That is not so very much."

It was a lie so familiar that it no longer even stung.

He dressed in the dark, by touch. Shirt, with its thread. Waistcoat. The grey glove, drawn over the left hand with a care that was almost tenderness, because the glove was the one thing in his life that did not ask anything of him. Boots. Coat. He stood for a moment in the middle of the narrow Warden's room, with its narrow bed and its one shelf and its single window cut like a slot in the wall, and listened to the sea breathe.

In, for ten. Out, for ten.

And, below, a long way below, in the workshop at the foot of the tower, a very faint sound of someone moving about already. A bucket set down. A shutter drawn back. It was not yet the fourth hour of the morning. She had slept, at best, five of them.

He found that he was listening to her walk.

He stopped himself, and was annoyed with himself, and went on listening anyway.

*

She had asked the night before, at supper.

It was the clause she had made him keep, the thing she called asking, and she did it the way she did everything, directly and with her chin a little raised, as though braced against a refusal. She had been spreading butter on bread and had not looked at him. "I'd like to see the reading," she said. "The dawn one. I've been in the vault when you've done the work, but never the whole of it. I'd like to know what it costs."

The knife in his hand had stopped.

"I would not call it a spectacle."

"I'm not asking for a spectacle. I'm asking to be there." She set down the bread. Her fingers did something odd as she did it, a small fumble, as though the bread had been farther away than she had judged. She curled them into her palm and smiled at him, a little too quickly. "You said you'd ask. This is me asking."

The proper answer was no. He had known it was no as she spoke. In nine years no one had stood on the reading stair at dawn. The old Warden had done it alone, and had taught him to do it alone, and had said, in his dry light voice, that a thing which cannot bear to be seen is a thing that has not yet been understood. He had not believed that, then. He had believed that the reading was the one private hour a man had left, and that he would keep it as long as he kept anything.

He had said, "At the quarter before the bell."

She had looked up, startled. Then she had smiled again, and this time it reached all the way to her eyes, and he had looked down quickly at his own plate, as one looks away from a lamp.

So she was waiting for him at the foot of the stair, in the cold blue dark, with a lantern and a coat over her apron, and she had braided her hair so tightly that it looked like a rope. She had not been late. He suspected she had been early. She looked, in the lantern light, absurdly young and entirely determined, and the first thing she said was, "I have a clause about this."

"You have a clause about everything."

"If it gets to be too much, you stop. You don't push through it to save face. You say so."

"It is a reading, Conservator, not a duel."

"It looks like a duel," said Maren, "from the outside."

He did not answer that. In his head, since the stairs on the third day, he had stopped calling her anything else. He had said it once to her face, in an unguarded moment, and watched it go through her like a pin. Aloud he kept the title, like a sleeve over a wound. It was a small dishonesty. He was beginning to notice how many of those he had.

They went down together, in step.

*

The Reading Stone lay at the foot of the well, below the sill, where the stair ended on a shelf of black basalt no wider than a doorstep. It was the oldest thing in the tower. The water here was deep and green and utterly still, and it was cold in a way that was not about temperature. In nine years he had never been able to look straight down into it for long.

He set the lantern on the lowest step. "You will stand there," he said. "On the third stair, behind the rail. You will not speak, and you will not come down, and you will not touch me. If I fall, you will not try to catch me."

"That's the stupidest rule you've made yet."

"It is the oldest."

"I'm going to ignore it."

"I know," said Tavian, and it came out gentler than he had meant.

He took off his coat, and folded it, and laid it on the stair. He rolled his left sleeve past the elbow, and took off the glove, and did not look at her while he did it. He knelt on the stone. The cold of it came up through his knees like a hand. He drew breath, a full one, the first of the day, and put his left hand into the water to the wrist.

The pages answered.

They always answered. It was not a voice. It was a pressure, a pull, as when you put your hand into a river and the whole weight of the current finds your fingers at once. Forty of them, hung in the dark above him, each pulling at him in its own measure. He did not hear them. He felt them, along the line of the black ink in his arm, each one a different quality of tension: Sennet, a sore, wincing thing, healing; the Gull's Teeth, brisk and sharp; Marrow Water, slow and heavy; and on, and on, through all their names, which he said aloud in the old tongue, one after another, in the low flat voice his teacher had given him.

"Sennet. Low and mending."

A long breath of sea. The bell, far above. He felt the answer settle in his arm like a stone dropped in a well.

"Gull's Teeth. Steady. Marrow Water. Steady. Karn Reach..."

He stopped. It was only a half breath. The page lagged, a small dull weak thing, like a pulse that has missed a beat. He pressed on it with his mind, as you press on a bruise to learn how deep, and it gave, and a white thread of pain ran up the inside of his arm from wrist to elbow and a long way past it.

"Karn Reach," said Tavian, evenly. "Failing. Slow."

He did not look round. He knew, without looking, that on the third stair behind him, a woman had stopped breathing.

He went on.

It was a strange thing, to be watched. He had expected it to be an intrusion. He had braced for it, the way you brace for a cold wind. But as the names went by, the Long Keel and the Hollow Ring and the Three Sisters, he found that the attention coming off her was not like a stare. It was like the warmth of a stove in a room where he had sat for nine winters without noticing it was cold. It did not press. It held. It lay along his back like a hand that did not quite touch, and he found that his voice, which had been flat and tight since the first night, had loosened.

In nine years, he had done this alone, and the aloneness had been the shape of it. He had thought that was the nature of the work. He had never considered that it was merely the nature of the room.

"Rooks Ferry. Steady. The Narrows. Steady. The Long Keel..."

The page at the end of the reading stuttered.

It was the oldest of the forty, the greatest of the currents, the one that held the whole southern run from the Rest to the open sea. In nine years it had never stumbled. Now it rose against his hand like a living thing, and fell, and rose, and he felt the whole slow weight of the water above him shudder.

He had expected it. He had felt it in the night. It was the page he had been dreading for a year. And knowing did not help at all.

Pain came up his arm like fire through a fuse. It was white and whole and for a moment he could not see. He heard the bell, high and wrong, ring a full beat early, and his voice said something. He did not know what. His vision narrowed to a green point. The stone swung out from under his knees.

She was there.

He did not hear her come down the stair. He knew only that there was a pair of hands under his right arm, strong and small and ferociously steady, and a shoulder against his chest, and a voice at his ear saying, "I've got you, I've got you, don't you dare, I've got you," in a tone he had never heard from her, with no wit in it at all.

"I said..." His own voice was a stranger's. "I said you would not..."

"I heard you. I'm ignoring you. Hold still."

He did not hold still. His arm was still in the water and the pull of the Keel was still on it, and she had one hand on his shoulder and the other closing over his right hand where it had clutched the stone. He felt it. That was the thing he would remember. He felt, through the white roar in his head, her fingers close over his, and they were cold.

Not ordinarily cold. Not the cold of a woman who has come down a stair in the dark. They were the cold of something that had been left outdoors. They lay over his knuckles like a handful of river stones, and he thought, distantly, with a clear small chill that went in under the pain: that is not right. That is not right at all.

Then the Keel eased.

It let go of him all at once, as a tide lets go of a boat, and the pain drained out of his arm like water from a basin. He drew his hand from the pool. It came out dripping and shaking, and he held it against his chest, and bent over it, and breathed.

She did not let go.

She was kneeling on the basalt beside him in the green light. Her hair had come loose on one side. She had both her hands wrapped around his right, and she was looking at him with an expression so open, so frightened and furious and plain, that he could not hold it for more than a second.

"Is it over?" said Maren.

"It is over."

"How often does that happen?"

"It does not." He swallowed. "It does not happen. It has never happened at the Keel."

"It's the oldest page."

"It is."

"And you knew."

"I suspected."

"No hidden pages, Tavian." She said it low, and not unkindly, but with a thread of iron in it. "You said you'd keep it."

"I am not hiding it." He heard how thin that was. "I am telling you now."

"After it nearly put you in the water."

He could not argue with that. He did not try. He sat with his shoulder against the cold stone of the stair and his hand in hers and felt the warmth, which he had no right to, creep back into his fingers, and he was angry with himself for it. It was absurd. It was a hand. It was a small cold hand with the stain of ink in the fingertips, holding his out of the pure ferocity of her professional conscience. It meant nothing. It was only that no one had done it in nine years, and his body, a stupid, loyal, starved animal, had not known how to refuse.

He looked at her fingers over his.

And he thought of another pair.

It came to him whole, without being called. A low stair in the same tower, nine years gone. A woman standing in the grey light at the head of it, with her coat belted wrong and her hair coming down, and a thumb with a small pale crescent scar across the base of the nail. She had held his hand exactly like this. She had pressed a folded scrap of paper into his palm and closed his fingers on it with both of hers, and her fingers had been as cold as these. Promise me, she had said. Her voice, even then, had been low and rough and a little amused, as if she had found the whole of the world faintly absurd and had decided to love it anyway. My daughter has my hands. If she ever comes, if she ever finds a way, she will want to put them to the page. She will want to mend it. Do not let her touch the Oath. Whatever she says. Whatever it costs you. Promise me.

He had promised.

He had been twenty-two, and his teacher was already half gone, and the woman had been shaking so hard that the paper in his hand had rattled. He had said yes because he could not have said anything else. He had meant it, entirely. He had been certain, standing on that stair, that he was agreeing to a thing that would never happen. A girl who lived in another world, across a door that had not opened in the memory of any living man.

And now the door had opened, and the girl had come through it, and she was kneeling on the Reading Stone with her mother's hands, holding his.

He took his own away. He did it slowly, as gently as he could, and he saw the small flinch go across her face and be put away, and hated himself with an intensity that surprised him.

"Thank you," he said. "I am recovered."

"You are not."

"I am sufficiently recovered to climb a stair."

"That's not the same."

"It is the standard I hold myself to."

She looked at him for a long moment, kneeling there on the black stone, and he thought she would argue. Instead she stood, in one smooth movement, and held out her hand to help him up. It was her right. It was the cold one.

He took it. He could not have said why.

*

They climbed to the balcony because he always did.

It was the last part of the reading, the part that had no purpose except habit. He went up the narrow stair past her round room, with its closed door, and through the low arch, and out onto the stone. The sky was beginning to pale in the east, a long grey band like a sheet being drawn back. The sea lay under it, black going to pewter, breathing. He walked to the rail and stood with his left hand held out over the water, palm down, and felt the tide against his skin as a faint cool pressure, like the memory of a touch.

She came and stood beside him.

Not close. About a yard. She had pulled her coat around her, and her hair was blowing, and she was looking out at the sea with a face he could not read in profile.

He was thinking: I will never let her near the Oath.

It came to him as plainly as a sum. He would keep his word. He would keep it as he had kept it for nine years, in an empty tower, in the dark. And the only way to keep it was to keep her from the truth, because the truth was a door and she was a woman who walked straight through doors. Every day she stayed was another day on which he would have to choose, between the vow and the clause, between the promise he had made to a stranger on a stair and the promise he had written, in his own small neat hand, on a sheet of fish-tally paper. Neither of us keeps a page from the other.

He had signed it knowing he could not keep it. He had known that when he signed.

He was a man who kept his word. It was nearly all he was. And he had given it twice, to two women, in two directions, and there was no road between them that did not run through a lie.

The light grew. A gull cried. In the east the first thin gold edge of the day came up over the water and laid a path across it, and he watched it come with a feeling he did not want to look at. It was not fear. He knew fear, he had lived beside it for nine years like a lodger. This was something much more dangerous, because it did not feel like a threat. It felt like warmth. It felt like the stove in a cold room. He realized that he had stopped thinking of her as the woman who would go when the Shallows opened. He realized that, somewhere in the last eleven days, he had begun to arrange his mornings around the sound of her moving about downstairs.

He needed her there.

It was a very small thought. It was the kind of thought a man could tell himself was nothing. He turned his face to the sea, because the sea was the only thing in the world that had never asked him what he was thinking, and fixed his eyes on the line where the water met the sky, and did not move.

"Tavian."

She had never said it twice. He heard that it was a different sound in her mouth than in his own head, quieter, with the t soft.

"Yes, Conservator."

"Does it hurt every morning?"

He did not look at her.

He could have said many things. He could have said it was the work. He could have said that pain was only information and that he had stopped listening to it years ago. He could have said, truthfully, that the pain at the Reading Stone was a fraction of what came afterward, in the small hours, when he lay alone in the narrow bed and felt the ink inch upward by the length of a grain of rice. He could have said: yes. Every morning. For nine years.

He thought of her fingers on his, cold as river stones. He thought of how she had gone white when the Keel stuttered, and of what it would do to her, if she carried this.

"No," said Tavian.

The wind came off the water. Somewhere below them, in the harbor, the first boat was putting out, and a man's voice called a greeting across the still bay.

He turned his head then, because he could not help it, and looked at her.

She was standing very straight, with her hands in her sleeves and her braid blowing across her cheek, and she was not looking at the sea. She was looking at his left arm, at the sleeve still rolled past the elbow, at the black line lying above the red thread. She looked at it for a long moment, and then at his face, and he saw that she knew. It was in her eyes, quiet and clear, with no accusation in them at all. She knew it was a lie. She knew he knew she knew.

She said nothing.

It was the first lie he had told her that she had let him see her see through. He could not tell whether it was a kindness. He stood on the cold stone in the rising light, with the sea breathing under his hand, and could not tell whether he had been spared or sentenced, and the sun came up over the water like a thing that had made up its mind.
