On Monday morning Hajin carried a pair of silver-rimmed glasses and an empty lunch box up to the twenty-second floor, and discovered that he had rehearsed the wrong sentence.

He had spent most of the weekend on it. In the kitchen on Saturday night, with the black notebook open and the glasses folded on the white counter beside a faded square of paper he did not look at, he had drafted eleven versions of what he would say. Some were brisk. *Your reading glasses. You left them in Room Three.* Some were dry. Some had an edge. One, written at two in the morning and crossed out so hard that the nib had torn the page, had run to four sentences and contained the word *please*. In the end, standing in the lift with the numbers climbing, he found that all eleven had gone and left behind only the plainest one, the one he had been afraid of.

Secretary Min rose when she saw him. Her face did the thing it did, arranging itself into perfect professional blankness around something very small.

"Mr. Yoon. The Director is in. She is not expecting you."

"I will only be a moment."

"Of course." Her eyes went to the lunch box under his arm, the navy cloth folded neatly on top. She said nothing about it at all, and the nothing was louder than a speech.

The office door was open. Seol Ahreum sat at the big desk in the grey light with a document held a hand's breadth from her face, and she was squinting. It was a small thing, a faint pucker between the brows, and it undid something in him that he had not known was tied. He had watched this woman read a quarterly report across a walnut table without a flicker. She had been doing it, he now understood, entirely by memory and willpower.

She lowered the page when she saw him. For half a second her face was simply open, startled and unguarded, and then it closed, as a hand closes over a coin.

"Mr. Yoon."

He crossed the carpet. He set the glasses on the blotter in front of her, and beside them the lunch box, wiped dry, its spring clip fastened.

"You left these," said Hajin.

That was all. It was the most ordinary sentence in the world, and it came out of him level and cool, in the voice of a man returning an umbrella. Nobody could have guessed what it had cost.

She looked at the glasses. She did not pick them up at once. Then she unfolded them and put them on, with both hands, in the slow careful way of a person assembling something she does not want to break, and her face came into focus in front of him. Her eyes behind the thick lenses were very dark and very tired, and she looked at him properly, perhaps for the first time since the sleet.

"The box is clean," she said.

"It is customary to return a vessel clean."

"I see." Her right thumb moved along the seam of her left cuff, and stopped. "Noted."

The cold went down the back of his neck. He had braced for it. It arrived anyway, thin and exact as a needle, and he held very still until it had finished.

"Good morning, Director Seol," he said, and turned to go.

"Mr. Yoon."

He stopped at the door.

"The agenda for Thursday is in your inbox."

"Thank you."

There was nothing else. He walked out past Secretary Min's studied blankness and rode the lift down, and somewhere between the nineteenth floor and the fourteenth he realised that what he felt was not relief. It was the opposite. He had gone upstairs braced for a fight, and she had given him a pair of ordinary words, and he stood in the polished steel box feeling like a man who has come to the door of a house with a key and found it open.

Taewon was waiting in his office with the blinds drawn and a printed sheet in his hand.

"Shut the door," he said, which in ten years he had never once had to say.

Hajin shut it. Taewon laid the sheet on the desk and turned it so that it faced him. It was an extract from the commercial registry, one page, with a company seal in the corner.

"Hanbit Advisory," said Taewon. "The vendor on the reserve entry. The one nobody could find."

"It does not exist."

"It exists now. It has existed for exactly six days before the first review meeting." He tapped the incorporation date with one finger. "Ten million won in paid-up capital. A single director, who turns out to be a nominee for a nominee. And a registered office in a serviced suite in Yeouido, on the ninth floor of a building that also houses the Seoul branch of a research firm the Strategy division has used for two years."

Hajin read the page twice.

"That is a coincidence of address."

"That is what I said." Taewon did not smile. "I also went to see the badge records. The intern, Nam Dayeon. On the night the vendor record was created in the Fund's system, under her login, her pass shows her leaving the building at 19:42. She did not come back until 08:55 the next morning. Someone created that record at two in the morning in her name, with her password, while she was on a bus to Gwangju."

"A login is not a person."

"No."

"Anyone who knew her password could have done it. Anyone, including Seol Ahreum."

"She could have," Taewon agreed. "And then she moved the girl to a safer desk before anyone had asked, and rewrote the entry afterwards with her own initials where the girl's had been." He lifted a shoulder. "That's a strange way to frame someone. You usually leave their name on it."

"She is clever."

"I know she's clever. I'm telling you what I found. You said no knuckles."

"This is a timestamp."

"It's a timestamp," said Taewon, and left it lying on the desk between them, white and square, like something neither of them wanted to pick up.

The restaurant on Tuesday was in Hannam, a quiet French place with plants in the windows and a waiter who moved like a man carrying a full glass. Yurim had chosen the table by the glass. She wore a soft yellow sweater and her hair in a loose knot, and she had ordered soup for both of them before he arrived, and had done it so naturally that he had sat down and begun to eat before he noticed it was something he would have chosen.

"You look better," she said.

"I'm eating."

"I can see." She smiled. "I told you, restful ally. I notice things and I stay quiet about them."

He waited until the plates were cleared. He had decided, on the way over, that he would not use any of the eleven openings he had prepared for the other conversation. He would simply ask.

"Reference RD-0112."

Her spoon paused for the smallest fraction of a second. Then it went on, down into the bowl, and came up again.

"Oh, that." She said it lightly, with the faintly rueful air of a woman asked about a family scandal at a dinner party. "Everyone in the family knows that one. Where did you find it?"

"In the archive, on Friday night."

"Yes, I heard you were up there late. Min mentioned it." She touched her napkin to the corner of her mouth. "A family of three. A girl, a mother, a father. It was an ugly business. The girl had got into some kind of trouble at school, and the parents were making noise about it. Naturally the school wanted it quiet, and so did Grandmother." She lowered her voice. "So she wrote a cheque and put them on a plane. Forty-one million won, I think. It's what money is for, in our family. Ahreum has spent twelve years making sure no one asks."

"The line has words in it."

"Because even Grandmother couldn't bring herself to reduce it to a code. That's the only decent thing about it." Yurim sighed. "I'm sorry. I did try to warn you. She is not what she looks like, Hajin. She is the one who asked for it. I saw the request myself when I was a girl."

"The requested-by field is blank."

"Of course it is."

It had come so quickly. That was what he noticed. Not the content, which was plausible, tidy, and damning in exactly the way he had been trained to want. It was the speed. The answers arrived like water finding a channel already cut for it, without a hesitation or a search. He had interviewed a great many people over the years, and the honest ones paused. They went looking for the thing. They said *I think* and *I may be wrong*. Yurim never paused.

He heard himself say, in the mild voice he used for questions he already knew the answer to, "Who told you the consent dates in Annex D were wrong?"

"A friend in Compliance."

"Which friend?"

"I'd rather not say. They would lose their job." She tilted her head, and her smile came up.

It came up late. He watched it. He had been counting without knowing, and now he counted on purpose: her eyes met his, and stayed, steady and unreadable, and one half beat later the corners of her mouth rose to join them. It was a very small delay. It was the length of a person remembering that a face was supposed to do something.

He wondered how many times he had looked at it since the first lunch and told himself that he was imagining things.

"Of course," he said. "I understand."

He finished his coffee. She talked about easier things. He listened, nodded, said the right words in the right places, and thought of an old shirt button that had always been slightly loose and that he had pressed a thumb to every morning for a year, and had never sewn on, and had one day found missing.

The Daon pension fund kept its offices on the thirty-fourth floor of a building in Yeouido, behind a reception desk of white marble and a wall of dark glass. The investment director was a heavy, courteous man in his sixties called Lim, with a handshake like a warm sandbag and an air of having been told a great many lies by clever people and having forgiven them all.

"Mr. Yoon." He waved him to a deep leather chair. "Thank you for coming. I must say, I had half expected to find you more difficult to meet."

"Difficult?"

"Your reputation in Seoul is for being very hard to reach." Mr. Lim smiled. "But Director Seol was clear that you would be perfectly reasonable."

Hajin did not move.

"Director Seol?"

"She telephoned me on Thursday evening. Quite late." Mr. Lim folded his hands over his stomach. "I confess I was surprised. We do not often hear from the Seol family directly. She said that if Mr. Yoon of Maru Learning should request a meeting about our holdings in the education company, I ought to hear him out in full, before the board's people did. She asked me, in fact, not to hurry."

"Did she say why?"

"She said that the future of the Scholarship Fund would rest, in the end, on whoever held the balance." Mr. Lim paused. "And that she would prefer it rested on someone careful."

The office was very quiet. Through the dark glass the Han lay flat and grey under the winter sky, with a long barge sliding down it, slowly, towards the sea.

*Thursday evening.* That was the night of Annex D. That was the night he had said, in front of a room full of directors, a sentence that had turned her face the colour of paper. She had gone home, or somewhere, and she had picked up a telephone and spent part of her evening arranging for the man who had hurt her to be taken seriously by a pension fund.

"I see," said Hajin.

It was the first time in his life that he could not think of a second sentence.

"Is she sabotaging me or helping me?"

The car was crossing the bridge in the early dark, and Taewon, in the opposite seat, looked up from his tablet. The question had come out of Hajin without his permission, and it hung in the warm air between them like a cough.

"I'd say that depends on what she thinks you're doing."

"She is meant to be stopping me."

"Is she?"

"She takes every blow and says nothing. She signs every clause. She gives me the reserve. She tells Daon to listen to me." He pressed the heel of his hand to his forehead. "Either she is the best strategist I have ever met, playing a game so long that I cannot see its edges, or"

"Or."

He did not finish it.

"There's a third possibility," said Taewon, after a while.

"What?"

"That she isn't playing you at all." He said it quietly, looking out of the window at the lights going by. "That she's doing the thing she's doing, and you happen to be in the way of it."

"That is not a possibility. That is a wish."

"Maybe," said Taewon. "I've been wrong before."

He was silent for the rest of the journey.

There was an unsent email in the drafts folder of his laptop.

He found it at ten that night, in the back of the office with the lights off, when he went looking for something else. The subject line read *Reserve: questions for Thursday.* He had written it on Sunday, in the grey hours, in a mood he now struggled to recall. It ran to four numbered questions, each sharper than the last. They concerned RD-0112, and the blank line in the green book, and the identity of the person who had asked for a family to be sent abroad. The fourth said, in the careful courteous language he used when he meant to wound: *I would be grateful to understand whether the Fund's stewardship has ever been guided by anything other than convenience.*

He read it through.

It was a good email. It was exactly what he would have written three weeks ago, with a kind of cold pleasure, and sent. He could feel the shape of the pleasure even now, like the print of a hand in warm wax. It had been so easy to be that person. He had been so good at it.

He thought of a woman squinting at a page held a hand's breadth from her face.

He selected the draft and pressed delete. The window asked whether he was sure. For a moment his finger rested on the key, and he was aware that this was not a decision about an email.

He was sure. He pressed it.

It made no sound at all. The screen went blank and clean, and he sat in the dark with his hand still half raised, feeling as though something he had been holding for ten years had slipped, very gently, out of his grip, and he had not tried to catch it.

The door opened without a knock. Taewon stood there with his coat on and a sheet of paper in his hand, and his face had the stillness it wore when he had found something he did not like.

"The Luxembourg seller," he said. "I finally got the shipping side of it. When the first block of shares was transferred two years ago, the original paper certificates were couriered to Seoul by a logistics firm called Haneul Express." He put the sheet on the desk. "Haneul Express has exactly one account in Seoul that uses the same pickup address and the same billing contact. A research vendor. Yeouido, ninth floor."

Hajin looked at the page for a long time.

"The same building as Hanbit Advisory."

"The same suite."

"That could be a coincidence of address."

"It could," said Taewon, and did not say what he thought of it.

The phone on the desk lit up. Hajin did not need to turn it over to know whose name was on the screen. It was a quarter to eleven. He read the message upside down, in the cold blue glow.

*Tonight free? I have something you should see. :)*

He sat looking at it while the city went on glittering behind the glass, and the paper from Haneul Express lay under his left hand, and the little yellow smile at the end of the sentence waited, patient and warm, for him to say yes.

He had answered every message she had ever sent him within the hour. It had been the first thing Taewon had noticed.

He turned the phone face down on the desk. He did not answer.

It was the first time.
