On Saturday morning Matteo took her down a path she had not known existed.

It began behind the kitchen garden, beyond a gate in the wall that Mrs. Venn unlocked with a key the size of a trowel, and it went down through the cypresses in a long slant of worn stone steps cut into the cliff. The snow had not reached it. The air was cold and bright and smelled of resin and wet rock, and below them, through gaps in the dark trunks, the sea lay flat and silver, with a thin white seam where it met the shore. He walked ahead of her with the hamper in his good hand. Every few steps he stopped, and looked back, and held out the other, the bandaged one, palm up, and she put her fingers in it and went down a little further.

"You are going to tell me it is a surprise," said Sienna.

"It is a surprise."

"I do not like surprises."

"I know." He smiled at the step in front of him. "That is why I am taking so much trouble over this one."

Marco had not come. He had stood at the head of the stair in his dark coat with his newspaper under his arm and said, in a voice of perfect neutrality, that he had a great deal to do at the quay, and that he would be at the end of the telephone line, and that Mr. Bellandi would not need him before dark. Then he had looked at the ceiling of the sky for a very long time. Mrs. Venn had packed the hamper. It contained a loaf, a flask of soup, a jar of apricot jam, two cups, and at the bottom, wrapped in tissue, a single green-gold pear. There was no card. There did not need to be.

The path ended on a shelf of shingle. A small cove opened out below the cliff, a bowl of gray stones and black weed with a ruined jetty running into the water. At its landward end, tucked under an overhang of rock so that it was invisible from above, stood a long low building of weathered timber, silvered by salt, with a roof of mossy slate and two tall doors at the sea end, closed with a bar. A faded blue shutter hung from a single window. There were letters over the lintel, painted once in white and mostly flaked away. She made them out, one by one.

L I V I A.

"My mother's boathouse," said Matteo. "Her family's, rather. It never belonged to the Bellandis. It was a wedding present from her father, in her own name, and she left it to me in hers." He set down the hamper and took a key from his pocket. "My father never came here. Not once. He said the sea at the bottom of the cliff was a damp, sentimental sort of sea."

"And you?"

"I come every week. I have done since I was twelve." He turned the key. The lock gave with a small oily sound, and the door swung inward on a dim, cold, sweet-smelling dark. "It is the only place in the world where nobody has ever asked me for anything."

He stood aside. She went in.

It was a long, high, shadowy room, floored with wide planks gone gray and smooth with age, and the light came in through gaps in the boards in thin gold blades that lay across the floor like fallen ladders. The air smelled of cedar shavings, and varnish, and old rope, and the clean cold smell of the sea. Tools hung along one wall in neat rows, planes and chisels and spokeshaves, each in its own outline of worn pale wood. A potbellied iron stove stood at the far end with its pipe going up through the roof, and beside it, on a pair of trestles, a boat.

It was a small one, perhaps twelve feet, lying keel up with half its planking stripped to the ribs. The ribs were new. The pale curve of the stem gleamed like bone. Where the old planks remained they were lapped one over the next in the clinker fashion, gray and cracked and beautiful, and a long white shaving still curled on the bench beside it as though the carpenter had stepped out a moment ago.

"She was my mother's," said Matteo. "A dinghy. She sailed her to Carrow on a dare, the summer she was nineteen, and was sick over the side the whole way. When she died, my father had her taken out of the water and left on the shingle to rot. I brought her in here the winter I was fifteen. It has taken me eighteen years."

"You are rebuilding her."

"Rib by rib. I am very slow." He crossed to the stove and knelt, and she saw that the kindling was laid already. He lit it with a single match. "I did not know how to do any of it. I learned from a book, and from an old man on Pier Two who used to come on Sundays and not speak." The little flame caught and climbed. "She has no name yet. The old one was Livia, naturally, but I did not like to put it back. I thought it was too much to ask of a boat."

She walked slowly round the trestles with her hand trailing along the new timber. It was warm to the touch. Someone had oiled it, lovingly, over and over, until the grain ran like water.

"Why did you bring me here?" she said.

He sat back on his heels, with the firelight on his face. "You asked me, in the library, what I would show you if I might. I said I could not think of anything that was mine." He looked at the boat. "This is the only thing I have ever made that nobody told me to. I should like you to have seen it, in case I never finish her."

"You'll finish her."

"Perhaps."

"Matteo." She stopped. "You will. I am telling you as a person who has watched a great many things not finish. You'll finish her."

He did not say anything. He only looked at her, with that quiet, dazed, unguarded expression, and she felt it go through her like warmth through cold hands.

The stove had begun to tick. They spread a blanket on the floor in front of it, on a heap of clean shavings that smelled of cedar and sun, and unpacked the hamper between them like children. She tested the soup. She tested the bread. She cut the pear in two with his penknife, and put half in his hand, and he ate his with the same grave absurd reverence he had given the first one, so that she laughed again, and he flushed, and it was all so simple that she felt it was a thing she might have stolen.

After a while he said, "I should like to ask you for something."

"Anything."

"Do not say that until you have heard it." It was her own phrase, and he gave it back to her with a small crooked smile. "Your book. The one you write in. I have not asked to see it, in all these months. I would not. But we agreed, in the library, that we would put what we know side by side. I have a book too. I have kept it hidden from you, and I would like to stop." He drew a breath. "I thought we might exchange them. Logs. Here, where no one is looking."

She sat very still.

Her notebook lay in her bag, three feet away, a blue cloth cover gone soft at the corners. It held every doubt she had ever had. It held the line about a card, and the line about a sideboard, and the small cold column of figures down the margin of a page. She had not shown it to a living soul. She had been trained since girlhood to keep her cards, and she heard in her head a voice from the long room above the quay, her own, saying: the first thing is to say what we know.

"Yes," said Sienna.

He went to his coat. He took out a small book, bound in black cloth, with a spine rubbed gray at the edges, and held it for a moment against his chest. It was thicker than she had expected. It had been written in until the pages had swollen. Then he came back and knelt in the firelight and held it out, in both hands, as a man hands over a sword.

She took it. She put her own into his, and he received it as carefully, and for a moment they sat face to face on the blanket, each holding the other's heart in their lap, and neither of them opened a page.

"Rule seven," he said quietly. "Read all of it. I shall not ask you to stop."

"Nor I you."

She opened the black book.

The first page was missing. She saw it at once: a ragged stub of paper stood in the gutter, a tongue of white along the spine, and the leaf that should have followed lay open on a line of date and ink. She looked up. He was watching her hands.

"The first page," said Matteo. "It is the day I woke. I tore it out. I could not bear to look at it." He did not look away. "It is in a drawer. I would rather not read it yet."

She waited. She gave him the silence, as one gives a drowning man a rope, to see if he would take it. He did not. His eyes stayed on hers, dark and level and open, and she knew it was true, every word of it, and she knew that it was not the whole of the truth.

She turned the page.

It began in the middle of a sentence. It was written in a small neat slanting hand that grew less neat as the pages went on, and every entry was dated, and every date was in the margin, in a column down the left. She had expected a diary. It was not a diary. It was a catalogue. It was the careful compiled evidence of a man who had been trying for two years to prove that a woman existed, and she read it as she would have read a case history, slowly, one line at a time, and it undid her entirely.

12 November. Gray raincoat, hood back. Canvas bag on the left shoulder. She does not look both ways at the Alder Street crossing; she looks at her feet and counts. She laughed at something the tall friend said. It changed her whole face.

14 November. She tests everything. Tea, coffee, a bun from the cart. The strips are yellow. She holds them up for the friend to see, like a conjuror. The friend rolls her eyes. They are very fond of each other.

19 November. Did not follow. Sat in the car for an hour afterwards. Marco brought water. I did not drink it.

She turned a page. A line of Saturdays. The market on Calloway Street. One apple, always the smallest, and a bench by the fountain. He had noted the day she bought a green one and made a face, and the day she gave the core to a pigeon, and the day it rained and she ate under an awning with her collar up and her braid wet and her eyes shut. 3 March. She hums when no one is near. I could not catch the tune. 17 March. It was the one her father whistles on the stair. 22 March. I should not know this. I should not be here. I am here.

She read faster. She could not stop. The entries thinned and darkened. The hand grew smaller. There were days with only a word, a single line: Nothing. Did not go. Went. And there, near the end of a gray winter, under a date in June, a longer entry that began without a heading and went down the whole of a page.

I drove to Tern Street at one in the morning. I told myself I would only look. There is a light on the second floor. She was up. I could see the shape of her through the blind, bent over a table, writing. I thought of the glass. I thought of her hand. I thought, if I could go in. If I could stand in that room and say, I know you. I know what you take in your coffee. I know that you were afraid and were brave anyway. If I could just say it once to someone who could hear.

I did not go in.

I sat under the lamp until the light went out. It was a quarter to four. I do not think I breathed.

The page blurred. She took her hand from the book and pressed her knuckles against her mouth, and the firelight ran and broke. A drop fell on the paper and she snatched it away, and wiped it frantically with her sleeve, and it left a small clean spot where the ink had faded.

"I am sorry," she said thickly. "I have spoiled it."

"No," said Matteo. His voice was very low. "It is the only part of it that has ever been touched."

She looked up. He was not reading hers. He had it open on his knee, unread, and he was watching her face, steadily, as he had watched the whole of that long night on a pier at sunset. The firelight lay along his cheek. He had gone white around the mouth.

"All the time," said Sienna. "You were there all the time. And I did not know. I was in a flat on Calloway Street writing about a card, and thinking I was alone."

"Yes."

"I hated you." She laughed, a cracked wet laugh. "For three months, in the lab, I made columns about you. I gave you a percentage."

"I know."

"You know?"

"I have not read a line of it." He smiled, a little crookedly. "But I have been watching you write it for three months, and you do not do it with your eyes. You do it with your jaw."

She made a sound. She set the black book down carefully on the blanket, closed, with both her hands on it. "Read mine," she said. "Please. All of it. I should like you to see what you have been living with."

He opened it.

She watched him read. It was the most frightening thing she had ever done. She sat with her hands pressed between her knees and her whole body drawn tight as a string, and she watched his face as it moved, line by line, down the first page. A bridal suite. A sideboard, bare. A card under a ribbon. The word Divergence, underlined twice. He turned the leaf. The pier at sunset, and a cup of coffee: He knew I would test it. The long room above the quay. A foreman on his knees. The pen that skipped on the second signature. His breath checked once at that, and went on. He read the page about the salt. He read, with a stillness that went on and on, the line she had written after the dinner: Last time, he never touched my glass. Last time I didn't know he would.

Then he turned over a leaf, and she saw him come to the margin.

It was only a column of small hard figures, down the edge of the page, each beside a pair of initials, each in a different pressure of the pen. M.B. 70. M.B. 70. M.B. 65. M.B. 60. And below it, newer, in a hand a little less steady than the rest, a line drawn through the last and a smaller figure written under.

M.B. 65.

He did not speak. His eyes went down the margin, and stopped, and went down again. She saw them pause at the date beside the last change, and she saw him understand what the date was. It was a Wednesday. It was the day her father had come, with a boat in brown paper.

He looked up.

It was a very long look. It was not accusing, and it was not afraid. It was a look she had seen only once before, on the face of a man who had just put a ring on a woman's finger and was waiting to learn whether it would stay there. His lips parted. The whole bright, tired, undefended architecture of his face seemed to lean toward her, and wait.

She held his gaze, and said nothing.

One second. Two. The stove ticked. A gull went by outside, crying once, and was gone.

Then Matteo looked down at the page again, and closed his eyes, and drew a slow breath.

"Sixty-five," he said, very quietly, "is higher than I deserve, and lower than I feared."

"It isn't for the glass," said Sienna.

He went still.

"I stopped believing you killed me a long time ago. I think the day you wept at the Registry Office. I just could not seem to stop writing the number." She drew her knees up and wound her arms about them. "It isn't for the glass anymore. It hasn't been for weeks."

"I know," said Matteo.

It was all he said. He did not ask what it was for. She saw the question rise in his face, and saw him put it down, gently, as one lays a sleeping child in a cot. He would not ask her. She understood that, with a feeling that was half grief and half tenderness. He would not ask, because he knew she would answer, and he was not ready to hear it. They sat there on a blanket of cedar shavings, two people who had given each other every key in the house but one, and each knew the other had seen the shape of the door. Neither of them reached for the handle.

It was a kind of cowardice. She knew it for what it was. It was also, she thought, with great weariness, the most loving thing she had ever seen two people do.

"Here," said Matteo.

He had turned the last page. There, at the end of her notebook, in a margin that had held nothing but a number, her own hand had written something once, in the night, on the fourth of December, and she had forgotten it. A single line, very small. He read it aloud, in a voice so soft that she could hardly hear.

"If he asks me to stay, I will say yes."

She put her hands over her face.

"I did not know you had written that," said Matteo.

"Neither did I."

He was very close. She had not felt him move. She felt the warmth of him, and the faint cedar smell of his coat, and the careful, trembling hover of a hand that did not touch her.

"May I?" he said.

"Yes."

His fingers closed gently round her wrists and drew her hands down from her face. He held them in his own, in his lap, between the two books. His eyes were wet and very bright. He did not smile. There was nothing in his face now but the plain, naked, trembling fact of what he was.

"Sienna," he said. "I will not ask. I told you that I wished to be chosen in the daylight. This is daylight. It is the middle of the morning. There is a stove, and a half-built boat, and a pear between us, and I should like to be the sort of man who asks." His voice shook. "But I cannot. I find I cannot make the words come. I have wanted it for so long that I am afraid, if I say it, you will hear the whole of it."

She did not know where the courage came from. It came up out of the very bottom of her, past every careful line she had ever written, and she heard herself say it clearly, as she might have read a result.

"Stay."

He did not breathe.

"Stay," said Sienna. "In this life. Please. I am not asking you to be anything. I am only asking you not to go."

It took a long time for the words to reach him. She watched them go in, one by one, slow and terrible and enormous, past the guard and the courtesy and the thirty-three years of care. Something broke in his face without a sound. He bent his head. His shoulders shook once, hard, and he put his forehead down against their joined hands, and she felt the hot wet fall of his tears on her knuckles.

"Always," said Matteo. It was hardly a voice. "Always. Always."

She freed one hand. She laid it on his dark head, and held it there, and felt it tremble under her palm like a bird. They stayed so for a long time. The stove ticked. The gold blades of light moved slowly across the floor and up the ribs of the half-built boat, until they lay along the pale new timber like a hand.

At last he lifted his head. He did not wipe his face. He looked at her, with that wondering, helpless, shining look, and she kissed him.

It was not like the other kisses. It was slower, and quieter, and without fear. There was no library in it, and no ledger, and no rule. There was a warm room, and the smell of cedar, and a man's mouth, trembling and salt and sweet. His hands came up, and cupped her face with a care that made her ache, and she thought, clearly, in the middle of it: this is what it is to be known, and stay.

"What shall we call her?" she said, when she could.

"I beg your pardon?"

"The boat." She drew back a little. "You said you wanted to be told."

He laughed. It was a broken, astonished sound. He glanced at the ribs, and back at her, and she saw him decide, very gravely, to be serious. "I should like," said Matteo, "to hear your suggestions."

"Pears."

"No."

"Gannet the Second."

"Certainly not."

"Then I'll think about it," said Sienna. "It is a very important decision. I may be some time."

"I have eighteen years," he said. "I can spare a few weeks."

They ate the rest of the bread. They sat before the stove while the afternoon went gold, and talked of nothing: the Gannet, and the old man on Pier Two who used to come on Sundays, and the best way to plane a rib without splitting it. She tried it herself, with his hand over hers on the long plane, and ruined a curl of cedar, and he laughed until he had to put his head down on the bench. The sun slid down the cliff. The sea turned from silver to rose. And somewhere in the middle of it, unnoticed, the thing that had sat on her chest all week turned over, once, and lay still.

It was dusk when they climbed the stair.

He went first, as before, with the hamper and the black book in his coat, and she came behind with her blue notebook pressed against her ribs. The cypresses stood black against a sky of green glass. A first star had come out over the sea. At the head of the steps the gate stood open, and beyond it the lamps of the villa were lit one by one, gold and small, like a promise.

He stopped at the gate. He turned, and held out his hand, and she took it.

"Thank you," said Matteo. "For coming down."

"Thank you for showing me."

"I should like to do it again."

"So should I."

He did not let go. They stood in the dusk with the cold coming up from the sea and the whole dark garden around them, hand in hand, and she felt, with the light, quick, terrible certainty of a woman at the top of a stair, that she was happy. It was a small bright thing, like a coin in her palm. She was afraid to close her fist on it.

And behind it, thin and cold, ran the line she had not been able to cross out. A torn page in a drawer. A boat in brown paper. A single sentence in a dead man's hand. She had held it all day, and had said nothing, and had let him say always into her hands. She thought: I will ask him tonight.

She thought it with her whole heart. She walked up the long gravel drive at his side, and into the lighted hall, and Mrs. Venn's voice called a welcome from the kitchen, and the great clock chimed the hour. She stood at the foot of the stairs with her hand in his, and looked up into his face.

He looked back. He did not say a word. He only waited, patient and tender and hers, with the lamplight on his hair.

And Sienna Hale, who had never in her life left a question alone, felt it rise to her lips, and felt his fingers close on hers, and knew that it was already, by one small and terrible degree, too late.
