The hospital had been built in the winter of 1974, on land that had belonged to a family of glassblowers for three generations before the war turned everything into memory and the war turned memory into something even less reliable.

Edward stood in corridor B on the third floor, where the fluorescent lights hummed at a frequency that seemed designed to grind down hope over time. He was twenty-seven, tall and thin in the way that comes not from dieting but from standing in hospital cafeterias watching coffee grow cold. His brother Thomas was two years younger, broader, the kind of man who still believed in the redemptive power of physical work even as illness stripped him of the ability to lift a tool.

They had not spoken in eleven days. Not since the telephone call from St. Jude's Ward, not since the nurse on the other end had used the word "terminal" the way people use umbrella terms—broad enough to cover everything, specific enough to mean nothing at all.

The corridor stretched between two rows of doors, each one bearing a numbered placard like the aisles of a library where the books had stopped reading themselves. Edward pressed his palm against wall 214 and felt the plaster beneath his fingers, warm from the heating system that had been broken since March and still broken because no one had the heart to tell the maintenance crew to come back.

Thomas lay behind door 216, and behind Thomas lay a diagnosis that the oncologist had delivered in a voice trained to sound certain about uncertain things. The man had spoken of survival curves and statistical baselines, of medians and quartiles, of numbers that described populations while saying nothing whatsoever about the person in the chair.

Edward was not a man who trusted numbers. He was a clockmaker by trade, or had been before the hospital bought the building and the lease and turned his workshop into a space for waiting families. He repaired timepieces—watches, pocket watches, carriage clocks with faces no larger than saucers—and he understood, in a way that his brother never would, that time was not a resource to be managed but a medium to be inhabited.

The door to 216 was open. Edward paused in the threshold and watched his brother sleep, breathing through a mask that fogged and cleared in rhythms that Edward counted without meaning to do so: one thousand one, one thousand two, one thousand three—

"Ed."

Thomas's eyes were open. They were the same blue they had been at seven, when they had fallen through the ice on the river behind their grandmother's house in Devon and Thomas had dragged Edward out by the collar of his coat while Edward coughed up English water and tried not to cry.

"You're counting again," Thomas said.

"I wasn't."

"Your jaw's doing the thing it does when you're counting. You've always done that when you're anxious. Mum used to say you could hear your teeth grinding from the garden."

Edward sat in the chair by the bed—the same chair where he had sat for eleven days, eating sandwiches that went stale and drinking tea that went cold and reading the same page of the same book over and over because the words refused to enter his head.

"How are you?" he asked, which in the language of brothers means: I am terrified and I don't know how to say it out loud.

"Like a man who's been given a number he can't work with," Thomas said. He smiled, and it was the same smile that had gotten them out of trouble at十四 when they'd broken Mrs. Pemberton's greenhouse window with a cricket ball. "But the nurses are good. Sister Halloway brought me a book. Dostoevsky. She says I should try to finish it this time."

"You never finished The Brothers Karamazov the first seventeen times."

"That's because I was distracted. There were girls in those days. Girls and football and the unbearable lightness of being invincible."

Edward looked at the ceiling tiles and counted the perforations across one panel: seventeen by twelve. Two hundred and four holes, each one a tiny mouth gasping for air that couldn't get through.

"I have something for you," Thomas said, and moved his hand toward the bedside cabinet where Edward knew, from watching him reach for it earlier that morning, that there was a small wooden box he had not had there before.

Thomas pulled it out. It was the size of a deck of cards, carved with patterns that Edward recognized as the same gear patterns he used in his clocks—interlocking cogs and springs and escape wheels rendered in walnut wood by a hand that was no longer steady enough to hold a chisel.

"I had made it before—" Thomas stopped, swallowed, tried again. "I had it made. Before the last admission. The carpenter at the hospice—he's very good. He said he could work from my sketches."

Edward opened the box. Inside, resting on velvet the colour of old bruises, was a pocket watch. But not just any pocket watch: it was a mechanism laid bare, its gears visible through a face of crystal so clear it was as if the watch were floating in air. The hands were moving, but not in any direction Edward could identify.

"It's beautiful," he said, which was inadequate, the way all compliments to the dying are inadequate—too small for what they're trying to carry.

"It doesn't keep time," Thomas said. "I wanted you to have something that doesn't keep time. Something that just... exists. Like you always said timepieces should. You're always telling me that a clock doesn't tell you what time it is—it tells you that time exists, that it's real and passable and worth measuring. So measure this one however you want, Ed. But don't count anymore. Not for me. Please."

Edward's throat tightened the way his father's had tightened before the stroke took his language and left him sitting in the armchair by the fireplace, pointing at the television news anchor and making a sound like a kettle boiling.

"I don't know how not to," Edward said.

"Then learn," Thomas said. "That's what you do. You learn. You were always the clever one. I was the one who could lift the heavy things. But you—you understood how the world worked underneath the surface. That's a different kind of strength, and you always were strong in that way, even when you didn't think you were."

Sister Halloway appeared in the doorway, a clipboard in her hands and eyes that had seen too much to be fooled by hospital optimism. She was in her sixties, with silver hair tied back in a bun that defied gravity and gravity's emotional equivalent: the refusal to let things fall apart.

"Mr. Thomas," she said, "you should be resting. And you, Mr. Edward—your sister phoned. She's on her way from Bristol."

Edward had forgotten about his sister. Charlotte lived in Bristol now, two hours west on the motorway that ran like a scar across the English countryside. She had called twice since the diagnosis, and each time Edward had let it go to voicemail, unable to bear the sound of her voice cracking the way their mother's had cracked on the telephone on the day Thomas was born—except that was wrong, Thomas was older, the day Thomas was born had been cold and bright and their father had come home from the hospital holding a wrapped bundle and said, "He's got your nose, Ed. And your stubborn chin."

"Charlotte's coming?" Edward asked.

Sister Halloway nodded. "She's bringing photographs. She said she'd found the albums from Devon. The ones with the river and the house and—" She glanced at Thomas. "The cricket ball. The greenhouse window."

Thomas smiled. "She always kept the memories. I was too busy living them to archive them."

The afternoon wore itself out through the window of room 216. Edward watched a crow land on the ledge outside and peck at something that might have been food and might have been nothing at all—the difference, in hospitals, was often imperceptible. He counted the crow's movements: one peck, two pecks, pause, three pecks, shake of the head, fly away. He stopped counting when Thomas's hand found his on the edge of the bed and squeezed it, once, in the way that meant: I know what you're doing, and I'm doing it too.

When Charlotte arrived at half past five, she brought with her three shoeboxes of photographs and a silence that was not empty but full—the kind of silence that exists between people who have loved each other long enough that words have become redundant, a shorthand of looks and touches and the pressure of a hand on a shoulder.

They went through the photographs together. Edward watched his brother's face change as he looked at images from a life that seemed, even to Edward, like the life of someone else: a boy of seven on the riverbank, a teenager of fifteen with a cricket bat slung over his shoulder, a young man of twenty in a pub with friends whose faces were blurred by time and alcohol and the happy oblivion of being alive and unwell.

"There's one," Charlotte said, holding up a photograph taken at Christmas 1989, "that Mum always said was your favourite."

It showed Thomas at twelve, standing in the snow in front of the house in Devon, wearing a scarf his mother had knitted that was too long and kept dragging in the snow. Edward was eight, standing beside him, looking at the camera with an expression that was somewhere between indignation and determination. Their parents stood behind them, arms around each other, smiling the way people smile in photographs taken when they don't yet know what they have.

Thomas reached for the photograph with a hand that shook—had always shaken, since the treatment had started three months ago, since the hair had fallen out in clumps and the skin had gone translucent and the body had become a foreign country that he was touring without a map.

"Mum's gone," he said, not looking at the photograph but through it, into some middle distance where the dead walked around in bodies that were thinner than air and heavier than stone.

"I know," Edward said.

"Dad too."

"I know."

"They'd like this. The hospital. Sister Halloway. You two, sitting here like... like boys again. It's what they'd want, to see you like this. Together."

Edward looked at his brother, really looked at him, in the way that brothers rarely do because looking requires seeing and seeing requires the kind of honesty that is easier in anger than in love, and what he saw was a man who was fading—not disappearing, not yet, but fading the way watercolour fades when too much water is added to the pigment, the colours running into each other until the edges of everything become uncertain.

"I'm here," Edward said.

"I know," Thomas said, echoing his sister, and then added, in a voice so quiet that Edward had to lean forward to hear it: "Don't count when I'm not looking."

They stayed until eight o'clock, when Sister Halloway came to check the monitors and announce, in a voice that managed to be gentle and factual simultaneously, that visiting hours would end in thirty minutes.

Edward stood at the door of 216 for a long time after Charlotte had led Thomas back to bed and settled into the chair by the window, watching the corridor lights flicker on one by one like candles at a vigil. He held the pocket watch in his hand, feeling its weight—lighter than he expected, as if it were made of something less dense than wood, something closer to memory.

He opened it again and watched the gears turn in their meaningless, beautiful circles. And for the first time in eleven days, he did not count. He let the hands move where they would, in whatever direction they chose, and he thought about what Thomas had said about time being a medium to be inhabited rather than a resource to be managed, and he understood, in a way that he knew would not last and was therefore all the more precious for its impermanence, that the only thing that had ever been real was the standing in corridors and the holding of hands and the counting of breathing rhythms when you were trying to convince yourself that the person you loved was still, definitively, alive.

The hospital clock in the main lobby struck eight. Edward closed the pocket watch, put it in his pocket, and went back to sit beside his brother's bed, where the fluorescent lights continued to hum and the plaster continued to feel warm beneath the palm and time, real and passable and worth measuring, continued to flow in whatever direction it preferred, indifferent to clocks and counting and the desperate human need to believe that if you just kept track, just measured and recorded and counted, you might somehow be able to stop it from running out.

But he counted anyway. One thousand one. One thousand two. One thousand three. Because that's what brothers do. They count. They watch. They wait. They love in the only language they have, which is presence, and presence is measured not in hours or minutes or seconds but in the quality of attention you bring to the room when the person you love is lying in it, fading, and the only thing you can do is sit and be there and pretend that the fluorescent lights aren't humming and the plaster isn't warm and time isn't running out.

Edward did all of these things. He sat. He watched. He counted. And when Thomas's eyes closed and his breathing changed from the rhythm of a man who is awake but tired to the rhythm of a man who has slipped beneath the surface, Edward opened the pocket watch, watched the gears turn their meaningless circles, and whispered: "I'm still here."

And that, in the end, was the only chronicle that mattered—not the fading of the body or the diagnosis or the statistics, but the simple, irreducible fact of presence: a brother sitting in a chair in corridor B on the third floor, watching another brother breathe, counting the breaths not to manage time but to inhabit it, to be inside it the way a clockmaker is inside the mechanism he repairs—hands steady, heart open, aware that every tick and every tock is a small miracle of gears and springs and human ingenuity, and that the only thing more sacred than fixing the machine is sitting beside the person who is fading and not letting go of their hand, even when the hand is no longer warm, even when the counting has stopped and the numbers have run out and there is nothing left to measure but the silence that follows.
