The Widow's Thread

Chapter One: The Second Knocking

The outer ring woke the way it always woke, with coughing.

Merryn Rusk heard it through the soles of her feet before she heard it with her ears — the small dry knock of it passing from raft to raft along the lashings, six or seven children on the Trewin platform, then the old man on the netting float, then somebody's baby. In the middle rings they said the outer ring sounded like a rope being sawn. In the outer ring they just called it morning.

She was already at work. She had been at work since the dark thinned, kneeling on a grating with her knees in three inches of warm bilge, sewing a patch of oiled hide onto the belly of the Trewins' raft where the sinew stitching had rotted out. The needle was whalebone, as long as her forearm and curved like a gull's wing. The thread was twisted sinew waxed with fish-fat, and it went through the old strake with a sound she had loved since she was nine years old: a small, wet, satisfied bite.

Thirty feet above her head, the sky was a blue so pale it looked scrubbed. Around the whole enormous rim of the world stood the wall.

You did not look at the wall if you could help it. It was easier on the mind not to. Twelve miles off in every direction it rose out of the flat warm water and went up until the eye stopped following it, a grey-green cliff of cloud turning and turning, so vast that from Ambry it looked motionless. Only at dawn, when the light came slantwise through the top of it, could you see the truth of the thing: streaks of vapour moving across its face at a speed that would take the skin off a man, and lightning crawling inside it like veins under a hand.

That was the Longturn. It had walked its slow circle on the ocean since before anyone's grandmother was born, and inside it, in the flat warm eye, the city of Ambry had drifted for two hundred years without once touching land.

"You're breathing through your mouth," Merryn said, without turning round.

Behind her, on the walkway, Tegan Wick shut her mouth.

The girl had been there an hour. She was always there. She had been there most days for three years, since she was twelve — sitting where Merryn had to see her, saying nothing much, watching her work with the flat, patient look of somebody tallying a debt. She was fifteen now and had got tall the way rope gets tall, all length and no give, brown hair cut short with a shell knife because long hair snagged in rigging. She wore a rigger's harness she had not earned and a scowl she had.

"That patch won't hold," Tegan said.

"It'll hold two years."

"The strake's rotten either side of it."

"Then in two years somebody sews the strake." Merryn drew the sinew tight, felt the plank take the strain, felt where it did not want to. "You could learn this. You've the hands for it."

"I don't want your trade."

"No," Merryn agreed. "Nobody does."

She had been the best stitcher in the fleet. That was not pride, it was record: nine hulls of her building were still afloat, and the wall-pilots had fought over which of them got her aboard for a crossing, because Merryn Rusk could put her jaw against a strake and tell you what the wall was doing thirty miles away. A sewn hull sings. Everyone in Ambry knew that much. Press your jawbone to the wood and you hear the water, and under the water you hear the storm, because a hull stitched with sinew and pegged with horn is not a box — it is a ribcage, and it breathes, and it listens.

Three years ago she had listened, mid-crossing, and got it wrong.

She finished the seam and knotted it and cut the sinew with her teeth, and then, because it was habit older than shame, she laid her cheek and jaw against the wet plank and listened to the day.

The Longturn's pulse came up through the wood. It always did. A long, low, unhurried beat, the sound a mountain would make if a mountain had a heart — one great compression of the whole storm, then the slow slack after it, then another, forty seconds apart, the same as it had been since she was a child. That beat was the first thing Ambry taught you to know and the last thing you forgot. Every hull in the city rang to it. Every rope street sagged and tightened to it.

Underneath it, this morning, there was something else.

Merryn went very still.

It was small. It was fast. It came in under the great beat like a finger tapping the far side of a door — nine or ten quick knocks, then a pause, then a broken scatter of them, then nothing, then again. It was not the wall. The wall did not tap. It was not a hull working; she knew the sound of every kind of hull working. It was not fish and it was not the anchor-kelp and it was not somebody's pump.

It was a rhythm, and rhythms in the water meant something alive.

She stayed down so long that the bilge soaked through to her hip and Tegan's shadow moved across her back.

"What," said Tegan.

Merryn sat up. Her face must have shown something, because for once the girl's expression had nothing in it but a child's plain curiosity.

"Put your jaw on the strake," Merryn said. "There. Where it's wet."

"I can't hear like you."

"Nobody can hear like me. Do it anyway."

Tegan knelt. She put her jaw against the plank and closed her eyes, and her face did the thing all faces did when the Longturn's pulse came up into the bone — it softened, briefly, the way it does when somebody hears their own house at night.

"Big slow one," she said.

"Under it."

A long silence. The Trewin children coughed. Somewhere a woman was calling a boy by three names at once.

"There's a — " Tegan frowned. "A knocking. Little. Like a bird in a basket."

"Yes," Merryn said. "Like a bird in a basket."

They looked at each other, and for one breath the three years were not between them.

Then the floor of the world tilted.

It was not much. A hand's width, maybe, across a hundred feet of lashed raft — but Ambry had no ground, only the sum of ten thousand sewn hulls roped together, and every one of them felt it at once. The bilge water in the Trewin raft slid to one side and stayed there. The walkway rope above Merryn's head, which had hung slack in the same curve her whole life, straightened and thrummed. All along the outer ring, lashings groaned in a chorus, a great creaking sigh like a crowd sitting down.

Somewhere behind them a raft-side burst and a woman began to scream about her hens.

Merryn was on her feet with her needle still in her fist. She turned to the wall.

The wall had changed.

On the northern quarter, where the cloud cliff had stood since forever, there was — less of it. It was thinner. Not a gap, nothing so simple; it was as though a hand had drawn the grey out sideways and stretched it, so that the cliff on that quarter looked pale and combed and much too far away, and the light coming through it was a sick, bright, shadowless white.

And the wall to the east and west had come closer. She could see it with her naked eye and no instrument at all: the curve of the horizon that had been a circle her whole life had been pulled long, into an oval, and Ambry was drifting in the fat middle of it.

"The eye's stretching," she said.

"That's not possible." Tegan's voice had gone thin. "The eye is the eye."

"Yes. Go and find your aunt. Tell her to double the outer lashings and strike every awning on the north side, and tell her Merryn Rusk said it, and when she spits, tell her anyway."

Tegan did not move. "Why the north side?"

"Because the wall's thin there, and a thin wall lets wind through, and this city has never once had wind in the streets." Merryn was already coiling her sinew, already counting, already frightened in the specific, useful way she had not let herself be frightened in three years. "Go."

Tegan went, three steps, and stopped. "The knocking," she said. "What is it?"

Merryn looked north, at the pale combed place in the wall, and the small fast rhythm was still going in her memory, patient as a pulse, tapping on the far side of a door that had never in two hundred years had a far side.

"Something outside," she said. "Answering."

She spent the rest of the morning doing the work that had to be done, because she was still a stitcher and the rim rafts were still coming apart. She put four temporary throats into the Trewin platform. She showed old Gwyther how to hitch a snubbing line so that when the swell came through it would take the jerk out of his moorings instead of out of his floor. She lifted a child off a walkway that had gone slack under her, and the child coughed into her collarbone, thin and wet, the outer-ring cough, the one the middle rings called wind-sickness and the outer ring just called the cough. She could feel the little ribs going like a bellows with a hole in it.

Nobody in the outer ring thanked her. They took her work — you did not refuse a stitcher's hands, whoever they belonged to — and they took it the way you take medicine from someone who has poisoned a well.

Nine people. That was the arithmetic they did when they looked at her. A crossing three years ago, a tow of two hulls, the wall bucking in a way she had told Hugh Tonkin she understood. Cut the tow, she had said, with her jaw on the strake and absolute certainty in her mouth. Cut it now or she'll take us both.

They cut it. The second hull went into the wall and the wall took it apart in under a minute, and the nine people aboard it went wherever the wall takes things, and one of them was Tegan Wick's mother.

At noon a boy came running along the rope street shouting that a skiff had come in off the north rim with a man in it who was burned.

Merryn stood up out of the bilge with her hands full of wet sinew, and knew, the way you know your own name, whose skiff it was.
