From the Agreement of Temporary Cooperation, Clause 9, in red carpenter's pencil on the back of a flour merchant's order form: "Neither Party shall keep from the other anything that matters."

For three days Wenxi lived inside a soap bubble, and everyone in Yunxi was kind enough not to prick it.

It began on the morning after the loft. She came down the narrow stair at six with her hair in a knot and her cardigan buttoned wrong, and found Grandma Su at the work table, folding dough, with her back to the door. Push. Turn. Fold. The old woman did not look round. She did not say a word about the pen, or the hour, or the fact that her granddaughter had come home through the courtyard at a quarter to one, barefoot, carrying her own shoes. She only said, in the mildest voice in the river country, "There is congee," and went on folding, and from somewhere deep in her chest, very low and very slow, came a tune that was not the wedding song.

Wenxi ate the congee. She tasted every grain of it.

The whole street seemed to know, and to have agreed on a policy. Auntie Zhou pressed a jar of pickled mustard greens into her hands and refused payment, and then, because that did not seem enough, a second jar. Mr. Qian, passing under the willow with his bird, lifted his hat to her with a gravity that would have suited a minister. The Wei sisters put a new hand-painted card through the shop door, with two doves on it, and this time they had agreed on the verse. Even the cat on the third flowerpot, which had spent the summer regarding her with weary understanding, rose when she passed and rubbed once against her ankle, like a person who has decided that a long argument is over.

And he came every morning at seven.

He came with a loaf from the tea house under one arm, or a bucket, or a plane, or nothing at all, and he stood on the step of the back door in his working clothes with the sun on his hair and said, "Good morning," in the low plain voice that she would have known at the bottom of the sea. She said it back. Then, since there was a green door in the wall and a jasmine bush that had survived a typhoon and not a single clause between the two of them, he stepped across the threshold, and put his hand against her cheek, and kissed her, quite slowly, in the shade of the leaves, while a thrush in the plum tree sang the same small phrase over and over like someone trying to remember a name.

She hummed all day. She could not stop. She caught herself doing it over the dough, over the till, in the middle of a sentence to a customer, and each time Auntie Zhou looked up from her string bag with an expression of such rapture that Wenxi blushed to the roots of her hair and hummed louder.

She was happy. It was a simple, enormous, unreasonable fact, like the weather, and she walked about inside it with her arms a little out from her sides, as one walks on a new floor.

On the fourth day, she rang Bai Ning.

* * *

She did it from the courtyard, at four in the afternoon, sitting on the rim of the stone jasmine pot with the chip in its corner. She had promised. She had written, Can I ring you tomorrow, and sent it before she could change her mind, and then the storm had come and eaten the tomorrow, and the one after. Six days. She felt every one of them as she waited for the call to connect.

"You," said Bai Ning.

It was the voice of a woman in a small bright flat three hundred kilometres away, with a cup of tea at her elbow and a pile of laundry she had been meaning to fold since Thursday. Wenxi shut her eyes. She could see the flat. She could see the yellow sofa, and the window with its view of a bus stop, and the shelf of cookery books that they had alphabetised together one rainy Sunday and then disagreed about for a year.

"Me," said Wenxi.

"You said tomorrow. It has been six tomorrows."

"There was a typhoon."

"I saw. It was on the news. A little town with a canal, and a woman in a yellow raincoat carrying a basket of eggs up a stair." A pause. "I thought, I know that woman. I thought, she's going to be all right, and I thought, I'm going to throw my phone at a wall if she doesn't ring."

"I'm sorry."

"Are you all right?"

"Yes," said Wenxi.

It came out by itself. She heard it, and she waited for the old brittle ring, the shop-window shine, and it did not come. It sounded like a plain word, spoken by a person who meant it. "I think I am. I think I'm better than all right. I've told people. I told the, I told someone. About the job. About the box." She drew a breath. "I told him."

There was a silence on the line so complete that she thought it had dropped.

"Him," said Bai Ning, in a very small voice.

"The carpenter. The one in the photograph."

"The one who, "

"Yes."

"Wenxi Su," said Bai Ning, "I am going to have to sit down." There was a thump, as of a person lowering herself onto a yellow sofa. "Tell me everything. No. Don't. I'll cry. Tell me the minimum. Is he kind?"

"He's very kind."

"Does he make you laugh?"

"He's the funniest person I know. He doesn't know it."

"Does he listen to you when you talk?"

"He knows the sound of my step," said Wenxi, and heard her own voice go thick, and Bai Ning on the other end made a noise like a kettle.

They talked for forty minutes. They talked about the pavement and the cardboard box, about Aurelle, which had been bought by a hotel chain and turned into a conference suite, about Bai Ning's landlord and the yellow sofa and a man at work called Doug who microwaved fish. The sun slid down the courtyard wall. The jasmine moved. Wenxi sat on the pot with her free hand pressed over her mouth and laughed until her ribs hurt, and thought, this is what it is not to be afraid of the telephone.

"I wasn't going to say anything yet," said Bai Ning at last.

She said it carefully. It was the voice of a woman setting down a tray with something on it that might spill.

"Say what?"

"It's probably nothing. It's only, I wasn't sure if it was fair. You sound so, you sound happy, Xi. I haven't heard you sound like that in seven years. I don't want to be the person who, " She stopped. "But I'd never forgive myself if I sat on it, either. So I'm going to forward you something, and you can delete it. And I'm going to say now that it's not an instruction. It's only a door."

"Bai Ning, what is it?"

"Check your email," said Bai Ning. "And ring me after. Please. Don't say fine."

* * *

It was there when she opened it, in the quiet of the little room under the rabbit, with the window open on the blue autumn dusk.

The message was forwarded, with a line from Bai Ning at the top in capitals, PLEASE READ ALL THE WAY TO THE END, and under it, in a clean grey font, the first email had been written by a woman she had never met.

Subject: Creative Director, Qiao Atelier.

Dear Ms. Su,

Bai Ning speaks of you often, and always in the same breath as the word peony. I am the founder of a new patisserie atelier in the old financial quarter. We open in November. We have a forty-seat salon, a production kitchen with six ovens, two floors of studio, and a team of eleven pastry chefs who are very good and who have no one to tell them what to make.

I am looking for a Creative Director. I do not want a manager. I want someone who can draw a cake nobody has seen before and make eleven people believe in it.

I have seen the portfolio that Aurelle published before it closed. I have seen the lavender cake, and the sugar peony, and a wedding piece with a cascade of pulled-sugar wisteria that I have not been able to forget for two years. I would like to meet you. I would like to offer you the position.

The salary is twice what Aurelle paid. There is a budget for research and for travel, and a studio of your own with a north-facing window. You would begin in the first week of November.

I will not rush you. I ask only for an answer by the sixteenth of October.

With great respect, Qiao Min

She read it standing up.

She read it again at the window, with the light going, and then a third time sitting on the bed with her bare feet drawn under her. Something happened in her chest that she had not expected. It was not fear. It was the thing before fear: a quick bright leap, a lift, as of a bird going up from a field. A north-facing window. Six ovens. She had not known that her whole body could still do that. She had thought it was gone, with the cardboard box and the offset spatula, that the part of her that drew towers of sugar had been left on the pavement outside the building. And here it was, wide awake, pulling at the lead like a young dog.

A cake nobody has seen before.

She put her hand over her mouth. She was smiling. She saw it in the dark glass of the window, a girl in a cardigan with a wild bright face, and she thought, with a kind of horror, Oh. I still want it.

The fear came a moment later, and sat down beside the joy, and neither of them said anything.

The sixteenth of October was five weeks off. She counted it on her fingers. The finale was before that, in the first days of the month. After the finale there would be the roof, and the prize, and the long slow business of mending a street house by house, with their own hands, as she had stood up in a hall and promised. She had said, I will raise the price. I will make boxes. I will do what I know how to do.

I said that, she thought. I stood in front of two hundred people and said that.

And I want this too.

It did not seem possible to want two things at once. She had been brought up in a house with one oven and one rule, which was that you did not ask for a second helping until everyone had eaten. She sat on the edge of the bed with the phone warm in her hand and the whole bright wide city opening in her mind, its salons and studios and glittering ballrooms, and a small cold voice at the back of her head said, quite pleasantly, you see. You are not made for a street. You never were.

And under that, deeper, a smaller voice, like an old tune. If you don't ask, nobody has to say no.

* * *

She went to tell him.

She was quite sure of it. She came down the stair with the phone in her pocket and her mind made up, and crossed the courtyard through the green door in the dusk, past the bush of jasmine and the rain barrel, with a speech forming itself as she went. Chengyan. I've had an email. It isn't a decision, it's an offer, and I'd like you to read it. She had it by heart before she reached the workshop. It was a good speech. It was exactly the length of Clause Nine.

The great double door stood open.

It was a soft blue evening, and the lamp over the bench was lit, and the whole long room lay in a warm gold dusk, full of the smell of oil and cedar. The tools hung in their rows. The radio on the shelf was playing something low. And at the bench, with his back to her and his sleeves rolled and his head bent, Chengyan was carving.

She stopped in the doorway.

He had a block of boxwood clamped in front of him, pale and close-grained, no bigger than the palm of his hand, and in his right fist was the smallest of the little chisels. The tip moved in tiny precise tickings, a fraction of an inch at a time. There was a thin pale curl on the bench. There was a drawing pinned beside him with a pin, a rough sketch in his square pencil, and she could see two long drooping branches on it, crossing, and crossing, and then at the end of each a single small leaf that had not been in the first.

He was humming.

It was a very small sound. It was the tune from the radio, or part of it, the thin cracked aria, but it had gone soft and domestic in his throat like a man crooning to a kettle. He did not know that he was doing it. She stood with the speech in her mouth and listened to a man who had once said that he did not sing, humming over a piece of wood, and her whole heart turned over.

He felt her. He always did.

"Don't look," said Chengyan, without turning round.

"I'm not."

"You are. I can feel it on the back of my neck." He laid the chisel down and put both hands flat over the drawing on the bench, as a boy covers a test paper. "It's not ready. It's the second one. The first had a chip in it, and I thought, if it's going to have a chip, it might as well be on purpose. So I'm, " He turned his head. He saw her face. The corner of his mouth went up, and his eyes crinkled, and it was the whole smile, wide and unguarded, the one he had given her once in front of three thousand people. "What?"

She opened her mouth.

I've had an email, she thought. Say it. It is five words. It takes about as long as a breath.

And she looked at him, at the pale curl of boxwood on his sleeve, at the drawing under his hand, at the long scarred fingers spread across a sketch of two branches that grew toward one another, and something went through her like cold water poured down a stair.

He does not ask for things.

She had heard him say it. In a boat shed, over a bowl of congee. If you don't ask, nobody has to say no. A boy of seven who had learned that a request is a weight, and that you do not hand weight to people who are already carrying a great deal. She had held that sentence in both hands, and she had thought, I will never make him ask.

And she thought, if I put this in front of him, what will he do?

She knew. She knew as one knows the shape of a step in the dark. He would read it. He would read all of it, slowly, to the end, with the careful square attention that he gave to a joint. He would lay it down. And then he would look up, with that grave and steady face, and he would say, quite gently, with his hands flat on the bench and not one muscle moving, that it was a very good offer. That she should go.

He would say it because he loved her. It would be the kindest thing he had ever done. And she would watch him do it, and it would be the cruellest.

"Flour," said Wenxi.

"What?"

"You've got, no. I have. There's flour on my, " She put her hand to her cheek, in a vague frantic way, and found, to her dismay, that there actually was. "I came to say that supper is at eight. Grandma's making the fish. She says you're to come."

"I'll come."

"Good."

"Wenxi."

"Yes?"

He was looking at her with his head slightly on one side, in the way that he looked at a board before he cut. She saw him notice something. She saw the shadow of a question cross his face, and hover, and wait. It was Clause Nine, and it was standing in the doorway between them with its hands folded, very polite.

She smiled. It was the bright one. She had not used it in nine days, and it came up over her face as a lid comes down over a pot.

"It's nothing," said Wenxi. "Don't be late."

* * *

She made herself a very good argument on the way home.

It took thirty paces, and it was extremely reasonable, and she delivered it to herself in the voice she had once used on difficult clients. It went like this. The clause said, anything that matters. An offer was not a thing that mattered. It was only a possibility. A possibility was a cake that had not yet been baked, a thing that might rise or might not, and nobody would say that a man had been lied to if you had not shown him the batter. She had not decided. She had not even begun to decide. When she had decided, she would tell him, at once, with the whole story laid out like a table, and it would be a fact, and a fact was what the clause was about.

Until then it was only noise. It would be a cruelty to hand him noise.

She crossed the courtyard. She stopped beside the jasmine, with her hand on the rim of the pot, and heard what she had said, all of it, in the stillness of the dusk, and it was so tidy, so neat, so beautifully built, that she felt her stomach turn.

It is in the afternoon that we begin to explain ourselves, said a small old voice by a damp bench on a canal. By the evening, my dear, we have explained ourselves right out of the thing we wanted.

It was seven in the evening. She was already out of it.

But she did not turn round. She went up to the little room under the rabbit, and sat down at the desk where she had done twelve years of homework, and opened the phone, and wrote, in the box under Qiao Min's grey signature, a reply of six lines. She deleted five of them. What was left said, Thank you. I am very honoured. Please may I have a few weeks. She read it. It was true, and it committed her to nothing, and it was the first lie of her life that she had told by being exactly accurate.

She sent it before she could think.

Then she rang Bai Ning, as promised, and said that she was fine, and heard her own voice say it, and hated every letter.

Supper was fish, steamed whole with ginger and scallion, on the big blue plate with the chip in the rim, and Grandma Su put the best piece on Chengyan's bowl without comment. He ate it with his usual grave attention, and said that it was very good, and told a long dry story about Zhaoyu and a ladder. The old woman laughed in the right places. Wenxi laughed too. She did it at exactly the right moments, and not once did the muscles of her face feel anything but strange, like a coat that had been cut for someone else.

He went home at ten. He stopped at the green door, in the dark, with his hand on the latch, and looked back at her across the yard, and said, "Goodnight," in a voice that held a good deal more than the word. She said it back. She stood and listened to his step go away across the cobbles, heel first, with its small hesitation, and then there was nothing but the thrush, and the stars, and a great quiet.

When she came into the kitchen, Grandma was at the sink.

She had the big blue plate in her hands and was washing it very slowly, turning it under the tap, drawing the cloth round the chipped rim, as though it were something that wanted careful handling. She did not look up. Her small straight back was turned, in the old blue apron, and in the warm yellow light her white hair looked as thin and soft as a dandelion.

"Xi Xi," she said.

"Yes, Grandma?"

"Is there anything you want to tell me?"

It was asked so lightly. It was the voice for the price of rice, or the state of the oven, or whether the fishmonger had been rude. But the hands under the tap had stopped. They hung quite still in the stream, holding the plate, and the water ran over them, and the old woman waited with her face to the window, as she had waited all that spring for the bread to rise.

Wenxi stood in the middle of the floor.

It was a clean bare moment. There was a door in it. She saw it as clearly as she had ever seen anything, plain and ordinary, painted blue, standing open on a bright wide room full of people who loved her, and all she had to do was walk through. I've had an offer, Grandma. It's a very good one. I don't know what to do.

She opened her mouth.

I will fix it first, she thought. I will find the answer, and then I'll bring it, tied up, like a box. I will not hand her a weight. She is seventy-four, and she has been carrying a shop for sixty years.

"No," said Wenxi. "Nothing. I'm fine."

The tap ran.

"Good," said Grandma Su, after a moment. "That is good."

She turned off the water. She dried the plate with great care, and set it on the shelf, and folded the cloth in three and laid it over the rail. Then she stood for a little while, quite still, with her hand flat on the dresser, where the old green book had once leaned between the salt and the sugar. She was not looking at her granddaughter. She was looking, with her mild unchanging eyes, at the dark window, and at whatever was in it.

Wenxi saw her face in the glass. It was only a glimpse. It was the kindest face in the world, round and lined and quiet, and for the space of one breath it was not smiling at all. It was the face of a woman who has asked a question knowing the answer, and has been told, politely, that there is nothing to say, and has decided, out of love, to accept it.

It was sad. It was so entirely and tenderly sad that Wenxi felt it in her teeth.

Then Grandma turned, and smiled, and patted her cheek with a hand that smelled of ginger and soap. "Go to bed," she said. "You are all elbows."

She went up the stair, and lay under the peony quilt with her eyes open, and did not hum.
