The world, as far as Clara could tell, was largely kept together by things that were on the verge of giving up.

It was true of the roof over the girls’ dormitory at St. Jude’s Home for Foundling Females, which sagged like an old donkey’s spine whenever the November rains came hard off the river. It was true of Mr. Povey’s knees, which popped like dry twigs every time he climbed the stairs to ring the rising bell. It was especially true of Clara’s pinafore, an article of rough, unbleached calico that had passed through the hands of four previous orphans before descending to her shoulders, where it hung like a damp shroud and smelled persistently of boiled cabbage.

At fourteen, Clara was neither pretty enough to be spoiled nor plain enough to be tragic, though she possessed an unsettling habit of staring at people’s cuffs.

"Stop that," Sister Agnes muttered, swatting Clara’s knuckles with the edge of a wooden ruler. The blow was more perfunctory than cruel, delivered with the mechanical rhythm of a woman who had spent thirty years trying to iron the crookedness out of other people’s children. "Look up, girl. Eyes on the stitch, not on the wall. A loose hem invites a slovenly mind."

Clara lowered her gaze to the grey wool sock stretched over her wooden darning egg. The wool was coarse, harvested from some wretched northern sheep that had likely died of spite, and it resisted the needle with every shove of her brass-capped thumb.

"It isn't a hem, Sister," Clara said mildly. "It’s a heel. And the yarn doesn't want to go that way. The twist is backwards."

"Yarn does not have wants, Clara. It has duties. Just as you do." Sister Agnes moved down the long row of trestle tables, her heavy skirts swishing like dry corn husks across the floorboards. "Work your row. The inspector comes at noon, and Heaven help the girl whose basket shows knots."

Clara did not argue, largely because arguing with Sister Agnes was like trying to persuade a milestone to roll uphill. Instead, she turned the darning egg in her palm and squinted at the grey fibers. To Clara, the yarn certainly did have wants. Everything that had ever been spun, woven, or spliced retained a stubborn memory of how it had grown. The wool remembered the brambles that had plucked at the fleece; the linen remembered the marshy mud where the flax had rotted; the hemp remembered the heavy salt of the rigging. If you pulled too hard against that memory, the thread snapped out of pure resentment.

If, however, you hummed a little into the eye of the needle—just enough to warm the cold steel—and gave the tail a quick roll between your finger and thumb, the fiber would sigh and slip through the weave without a fray.

She did it now, three quiet strokes, the yarn sinking into the thin spot over the heel until the hole vanished, swallowed by the surrounding wool as if it had never been worn through by the heavy boots of a carter’s apprentice.

"That's unnatural fast," whispered Minnie, the red-haired girl sitting three stools down. Minnie’s fingers were perpetually stained with blackberry juice or ink, and her own sock looked like a spider had attempted to build a nest inside a bird’s nest and then set fire to both. "How’d you do that? Show us."

"You have to let the tension go," Clara said under her breath, without looking up. "You’re strangling it, Minnie. You hold the needle like you’re trying to kill an adder."

"It bit me twice," Minnie grumbled, sucking a bloody thumb. "I hate wool. I hate thread. When I’m grown, I’m going to wear dresses made of tin. All riveted together by a blacksmith so they never come apart."

"You’d rust in the rain," Clara pointed out. "And you wouldn't be able to sit down."

"Better than darning," said Minnie.

The dormitory clock, a black marble monster with a broken pediment that had been donated by a guilt-ridden alderman, struck eleven with a wheeze. Across the workroom, sixty girls adjusted their shoulders at once. The sound of sixty needles dragging through sixty pieces of mending was like the sound of mice gnawing their way through the wainscoting.

Clara set her darning egg aside and picked up her apron. It was missing its top button again. It was always missing its top button. The buttons supplied to St. Jude’s were made of compressed pasteboard—cheap, chalky discs that dissolved into mush if they stayed wet too long and cracked in half if you leaned too hard against a wash-tub. Clara had tried five times to sew a proper bone one on, but bone buttons were property, and Sister Agnes had confiscated each one for the church bazaar.

In place of the button, Clara had tucked a bent brass pin through the linen, but the pin was blunt and regularly stabbed her in the collarbone whenever she sneezed.

"Clara Finch," a voice barked from the arched doorway.

It was not Sister Agnes, whose voice was like dry paper, but Mr. Povey. He stood in the frame with his hat in his hands, looking more than usually agitated. A speck of dried shaving soap clung to the lobe of his left ear.

"On your feet, Finch. Don't dawdle. Put your work in the dry-press and come along."

A collective murmur, like wind through dry rushes, rippled down the benches. To be called out of the sewing circle before the noon porridge could mean only two things: either your distant third cousin had died without leaving you any money, or someone had arrived downstairs with an indenture form and a guinea for the parish chest.

Minnie kicked Clara’s ankle under the table. "Don't go if he smells like fish," she hissed. "The fishmonger from the docks took Sarah Briggs last Martinmas, and she says she spends fourteen hours a day gutting herrings until her hair smells like low tide."

"He doesn't smell like fish," Clara whispered back, rising and shaking the grey fluff from her skirt. "He smells like nothing at all."

She followed Mr. Povey down the long, cold corridor where the portraits of past benefactors hung in grease-darkened oil frames. Every gentleman depicted had the same high, stiff collar that looked capable of decapitating him if he nodded too vigorously, and every lady wore a cap that resembled an overturned cabbage. None of them looked happy about having financed St. Jude’s, and Clara could hardly blame them; the place was thoroughly ungrateful and exceptionally cold.

"Is it the laundry?" Clara asked Mr. Povey’s broad, grey-clad back. "Because if it’s the laundry in Fishgate, I should tell you that the lye brings my hands out in blisters. I won't be much good with the sheets."

"It isn't the laundry," Mr. Povey grunted, his boots clumping heavily down the scrubbed stone stairs.

"A scullery, then? Mrs. Henderson said my arms were too thin for a spit-turner, but I can carry coal if the scuttle isn't larger than the ten-pound measure."

"It’s not a scullery, neither. And hold your tongue, girl. You talk like an ungreased wheel. She’s waiting in the front parlor, and the Matron has already brought out the good biscuits—the ones with the caraway seeds that come out of the tin only for the bishop."

Clara slowed her pace slightly. The caraway biscuits were legendary. They were kept in an octagonal tin behind the Matron’s tea-caddy and were reputed to be ten years old and harder than slate, but the mere fact of their appearance signaled an event of catastrophic respectability.

"Who is she?" Clara asked.

"A person of trade," Mr. Povey said, though his tone lacked its usual disdain for people who worked with their hands. There was a peculiar, cautious edge to it, like a man describing a dog that had never bitten him, but which looked entirely capable of swallowing his leg to the hip. "From over the water. Bramble Street."

"Bramble Street isn't over the water," Clara said. "That’s across the old bridge, behind the wool-wharves."

"I know where it is, miss, and you don't know anything about it. So shut your face and wipe your shoes on the mat. The real mat, not the rag by the door."

The front parlor of St. Jude’s smelled of beeswax, wet umbrellas, and seventy years of institutional damp. It was the only room in the house with a carpet, a Turkey rug so worn that the pattern had retreated into a few muddy red smudges near the hearth.

Matron sat behind the mahogany table, looking unusually small. Her hands, which were normally folded over her apron like two lard bladders, were twitching against her cuffs.

Opposite her sat the visitor.

Clara stopped on the threshold, her eyes dropping instantly—as they always did—to the garments.

The woman was neither young nor ancient, but she had the weathered, dry look of cedar that had hung in the smoke for several winters. She was small, hardly taller than Clara herself, and wore a cloak of dark green broadcloth that seemed entirely too heavy for the muggy spring morning. The cloak was fastened at the throat not with a brooch, nor with a ribbon, but with a single, immense button carved from dark cherrywood. It was shaped like an acorn, slightly flattened, and had four holes bored through its heart with absolute, hand-drilled precision. The thread holding it was not silk or linen, but three strands of twisted catgut, thick as twine and waxed till it shone like amber.

The woman did not look up when Clara entered. She was watching the steam rise from her tea-cup with an expression of faint boredom.

"This is the Finch girl, Madame," Matron said, her voice pitched half an octave higher than its usual disciplinary rasp. "Clara. Found on the steps of the chapel during the Great Frost. No name on her, only a scrap of an old flannel petticoat with an ink-mark that looked like an F. She is healthy, though slight. Her needlework is passable, though her temper is somewhat... wandering."

"Passable is not what I asked for, Mrs. Grote," the woman said. Her voice was surprisingly low, dry and rhythmic, like small stones rolling around in a tin pail. "A donkey's gait is passable, but you would not enter him at Newmarket."

"She has an eye for the cloth," Matron insisted, leaning forward. There was a distinct eagerness in the old woman’s grey jowls. She wanted Clara gone. Clara had a way of looking at the hem of the Matron’s Sunday gown—which was three inches shorter on the left side than the right—that made the good lady feel as though she were listing into the gutter. "She doesn't waste thread. Even the Sister admits she has a light hand with a backstitch."

The woman in the green cloak turned her head at last.

Her eyes were not the watery grey common among the townspeople, nor the dull brown of the marsh-dwellers, but a flat, pale hazel, like stagnant water over river pebbles. Her face was crisscrossed by dozens of tiny, purposeful lines—not the lines of worry or age, but the squint-creases of someone who spent eight hours a day looking through an eyelet no larger than a grain of mustard.

"Come here, child," she said.

Clara took three steps across the Turkey carpet. As she drew nearer, she realized that the woman did not smell of lavender, nor of the vinegar people used to ward off the marsh-fever. She smelled of mutton tallow, cold beeswax, and something sharp and metallic, like the taste of a copper coin held under the tongue.

"Hold out your hands."

Clara extended them, palms down. They were small hands, red-knuckled from the lye water in the scullery and scarred with dozens of pale white pricks along the side of the left index finger where the needle had strayed in the winter gloaming.

The woman did not touch them with her skin. Instead, she produced from her sleeve a small pair of shears—not the heavy iron scissors used for cutting flannel, but delicate things made of blackened steel, their finger-loops wrapped in thin green silk. With the blunt tip of the blades, she nudged Clara’s fingers apart, inspecting the nails, the joints, and the thick yellow callous on the inside of the right thumb.

"No rot," the woman observed. "Joints are straight. You don't bite the thread, do you?"

"Only when Sister Agnes isn't looking," Clara said truthfully.

Matron made a small, choked noise in her throat, but the woman in green only gave a single, hard nod that might have been approval or merely the filing away of a fact.

"A girl who bites her thread loses her front teeth by thirty," said the woman. "Steel shears are cheaper than false ivories, Clara Finch. Remember that. Why is your pinafore pinned?"

"The button broke, ma'am."

"What was it made of?"

"Paper-paste," Clara said. "It got into the wash-copper."

The woman reached into the deep pocket of her cloak. Her hand emerged holding a small, round object which she dropped into Clara’s palm.

It was a button, but like nothing Clara had seen in the supply baskets at St. Jude’s. It was made of common river-horn, semi-translucent, the color of weak cider, with two neat holes drilled through the center. When Clara’s thumb brushed the surface, she expected the oily, cold feel of dead horn, but the thing was warm. Not hot, but warm like a stone that had been carried in a pocket against a horseman’s thigh all morning.

More than that, it had a grain that Clara could feel without touching it—a grain that ran across the disc like the current in a mill-race.

"Well?" the woman asked.

"It’s too heavy for the calico," Clara said instinctively, turning the horn disc between two fingers. "If I sew this to this pinafore, the first time I catch it on a door-latch, the cloth will tear right out before the button lets go. You’d need three rows of linen tape behind the facing to take the pull."

The room was very quiet for three long ticks of the black marble clock.

Matron opened her mouth, likely to scold Clara for her insolence in criticizing the lady’s goods, but the visitor raised two fingers—short, square fingers with nails trimmed straight across—and the Matron’s mouth snapped shut with a small clack.

"She has the weight of it," the woman said to the wall. "She doesn't know the why, but she has the weight. That will do."

She rose from the chair. She was remarkably compact; her skirts fell in heavy, stiff folds that did not rustle as she stood, but settled around her like the lead weights at the bottom of a seine-net.

"Get your bundle, Clara Finch. One apron, one shift, one pair of boots. If you have any trinkets of your own, leave them. They only collect lint."

"Wait," Clara said, her fingers tightening around the horn button. "Are you taking me for the needlework?"

"I am taking you because your ears aren't completely plugged with porridge and your thumbs have some spring in them," the woman replied. She pulled a pair of heavy mittens over her wrists, leaving the fingers bare. "I am Mother Thimble. Some call me Mrs. Architrave, but they are usually lawyers or bailiffs, and neither have any business that concerns you. You will carry the bag, you will keep the floor swept of trimmings, and you will learn not to scream when you prick your thumbs on the cold brass. If you don't like it, the river is three doors down from my shop, and you may jump into it at your convenience."

Matron was already scrawling her name across the bottom of a grey parchment sheet. Her hand was shaking slightly, which Clara found very strange. Matron had sent girls off to the match-factories and the brick-fields without so much as blinking an eyelid, yet she did not look Mother Thimble in the eye as she exchanged the paper for two small silver pieces that made a dead, leaden thud on the mahogany table.

"The girl’s belongings are already at the gate," Matron said quickly. "A change of linen in a kerchief."

"Keep the kerchief," Mother Thimble said, turning toward the heavy oak door that led to the hall. "The flax was pulled green; it will be shreds before Michaelmas. Come along, Finch. Don't drag your heels. The tide is turning, and the ferryman waits for no one who doesn't have a double penny."

Clara looked back once.

The parlor seemed smaller now, like a box she had outgrown without realizing it. On the small side-table, the plate of caraway biscuits sat untouched, grey and hard in the cold morning light. Matron was already pulling the silver coins toward the edge of the desk with one blunt finger, her eyes fixed on the ink that was still wet on the indenture.

"Goodbye, Matron," Clara said.

The Matron did not answer. She merely waved one hand toward the hall, as if shooing a fly from the butter-crock.

Outside, the street was grey with the mist that rose from the estuary. It was not the soft, clean fog of the countryside, but the thick, coal-scented breath of a town that burned sea-coal and slaughtered pigs by the basin. Clara followed three paces behind the green cloak, her boots clattering on the slimy cobblestones.

She still had the horn button in her pocket. It pressed against her hip through the thin calico, steady and strange.

"Mother Thimble?" Clara called out, hurrying her stride to match the woman’s surprisingly long, swinging steps.

"Save your wind for the hill," the woman snapped, not turning around.

"Where is Bramble Street?"

"Behind the world, mostly," the old woman said. "And mind the dray-horses. If you get yourself mashed between the wheels before we reach the bridge, I won't get my two shillings back from that tallow-faced cow at the orphanage, and I hate an unbalanced ledger."

They turned the corner into Fishgate, where the smell of salted cod and wet horse-dung hit Clara like a wet towel across the face. For the first time in her life, she was outside the high brick walls of St. Jude’s without an iron chain on the gate or Sister Agnes's ruler behind her ear.

Her skirt had already gathered two inches of brown grease around the hem, her right boot had a hole in the sole that admitted the icy mud of the gutter with every third step, and the brass pin in her collar was working its way loose again.

Clara reached into her pocket, felt the hard, warm curve of the river-horn button, and for reasons she could not have explained to the bishop, the Matron, or even Minnie, she smiled.

The crossing over the Old Bridge was negotiated not by polite conversation, but by a series of sharp elbow-thrusts and a relentless forward momentum that made Clara suspect Mother Thimble possessed the physical density of an anvil. Carter boys with heavy loads of split timber yielded to her without looking up; draymen carrying hogsheads of porter swore under their breath, but wrenched their teams aside just enough to leave a dry channel of stones between their iron-banded wheels and the woman’s swinging skirts.

Clara kept her nose buried in the small of Mother Thimble’s back, shielding her face from the spray of mud thrown up by the passing traffic.

Below them, the river ran thick and yellow, choked with grease from the fellmongers’ yards upstream and the oily scum of timber-rafts awaiting the tide. It smelled like ancient mud and rotten rope, a heavy, cold stench that clung to the palate long after the mouth was shut. Clara had seen the river before only from the attic windows of St. Jude’s—a distant, leaden ribbon slicing the borough in half—but up close it possessed an alarming, sucking hunger that seemed entirely capable of swallowing horses, wagons, and stray apprentices without so much as a ripple.

"Don't look down at the weir," Mother Thimble said, her voice carrying clear through the clamor of iron hoops and shouting boatmen. "Water makes simpletons of the ignorant. It’s only wet dirt on the move. Keep your boots under your hips."

They left the bridge by an arched wynd so narrow that the eaves overhead met like clasped hands, shutting out the drizzling sky. Here, the noise of the main thoroughfare died away into a peculiar, damp stillness, broken only by the drip of gutter-spouts and the occasional clatter of a cooper’s mallet against oak staves. The houses leaned forward with their timber bellies protruding over the flagstones, their plaster walls greyed by centuries of chimney soot and patched with rough lath where the river-damp had rotted the lime.

"Is this it?" Clara ventured, jumping over a sluggish black rivulet that oozed from an alleyway.

"This is the Shambles-by-the-Wall," said the older woman, never slackening her pace. "The parish puts the slaughterers here because the blood runs down to the sluice by natural inclination. Bramble Street has no use for pig-stickers. We provide for our own leaks."

They turned twice more: once past a tallow-melter’s whose yard was stacked high with grey, fly-blown tubs that made Clara’s stomach perform an uneasy somersault, and once down an incline paved not with standard river-cobbles, but with flat, bluish stones that looked like slate taken from an old quarry.

At the foot of this slope, the character of the town shifted with an abruptness that made Clara pull up short.

The alley ended at an iron turnstile, green with verdigris and set between two high brick walls crowned with broken bottle-glass. Beyond it lay a crescent of three-story brick tenements, their fronts as straight and sober as the line of a carpenter’s rule. There was no mud here; the stones were swept so clean that the mortar between them looked like grey chalk, and the gutters on either side were dry, filled with gravel rather than sewage.

A painted board, hung from a wrought-iron bracket in the shape of a doubled bodkin, swung above the turnstile. It bore no crest or coat of arms, only three words painted in faded vermilion: Bramble Street, South.

"Push through," Mother Thimble commanded, giving Clara a small shove between the shoulder blades. "The gate has a catch on the lower rung. Don't trip it with your heel or it’ll take the skin off your shin-bone."

Clara squeezed through the iron bars. The metal gave a low, musical ping, like an oversized tuning fork struck against a hearth-brick. The sound hung in the air for several seconds, traveling along the row of brick facades until it died against the chimney-pots.

It was impossibly quiet after the roar of Fishgate. There were no dray-carts here, no dogs chasing offal, no street-criers howling about hot tripe or vinegar-eels. Yet the street was not empty.

Across the lane, an elderly man in a brown frieze coat was sweeping his front steps with a broom made of birch twigs. His movements were slow, rhythmic, and perfectly circular, as if he were measuring out the stone in round yards. At the window above him, a woman with a white linen cap sat behind a pot of pale pink geraniums, her fingers moving in an unvarying flash of steel that Clara recognized instantly as bobbin-lace.

Every house in the crescent had a door painted the same shade of dull, dark green, like stagnant dock-water, and every door was fitted with an identical iron knocker shaped like a closed fist.

"Step out," Mother Thimble said, passing through the gate without the slightest sound from her skirts. "The morning is half-spent, and the glue-pot won't stay warm by itself."

She led the way down the crescent toward the center of the arc, where the houses were taller and the roofs pitched more sharply toward the lead gutters. Number Seven sat between a shop with its shutters barred by three cross-planks of unplaned fir and a narrow, four-story tenement that had a small wooden lantern suspended from its second-floor balcony.

Unlike its neighbors, Number Seven had no geraniums on the sills. The front window was broad, bowed slightly toward the street, and divided into twenty-four small square panes of thick green crown-glass, each with a heavy, swirling bullseye in its center that distorted the shadows within. Above the lintel, a carved sign had been nailed flat to the brick:

M. THIMBLE & CO. Fastenings, Stays, Closures, and Repairs.

The front door had no keyhole. In its place, centered in the middle of the middle stile, was a circular plate of dull, unpolished brass about the size of a saucer. It was pierced by four large holes, through which a thick, tarred rope had been passed and knotted into a heavy cloverleaf.

Mother Thimble did not knock. She did not produce a key. Instead, she reached out with her bare thumb, found the uppermost loop of the tarred rope, and gave it a sharp, downward tug, as if clearing a catch in a spring-lock.

There was a muffled thud deep within the wood, followed by the dry, distinct sound of four heavy bolts sliding back in their channels simultaneously. The door gave a small, contented sigh and swung inward an inch on its iron straps.

"Wipe your boots on the scraper," the woman said, stepping over the threshold into the gloom. "Not on the stone. The stone is limestone; the vinegar from your shoes will pit it."

Clara dragged her feet across the iron scraper—which was shaped like an enormous, blunt tailor’s goose—and followed her through the door.

The interior of the entrance hall was cooler than the street, and smelled predominantly of things that had been boiled down and set out to dry: hide-glue, turpentine, the bitter nuttiness of crushed gallnuts, and an unmistakable underlying reek of sulfur that reminded Clara uncomfortably of the brimstone boxes the boys used for catching sparrows.

There was no hall-table, no umbrella-stand, and no hat-pegs. Instead, the walls from baseboard to ceiling were lined with shallow shelves, not an inch wider than the palm of a hand, and every inch of those shelves was occupied by round wooden pillboxes, each labeled with a small square of paper bearing a few neat strokes of black ink.

Clara caught glimpses of the writing as she passed: Oak-wart, 3-hole. Pewter-eye, small. Pike-jaw, heavy. Double-twist.

"Shut the door behind you," Mother Thimble called from the dark end of the passage. "Push until you hear the three teeth drop. If you don't hear three, push harder. We have neighbors who are somewhat too curious about the draft."

Clara leaned her weight against the heavy timber. The door had an astonishing heft to it; it moved without squeaking, but with the steady, oily resistance of a dock-gate. When it met the frame, three distinct iron clicks sounded within the thickness of the stile, one after the other, like a gun being cocked three times in a padded room.

"Now come in here and let’s see the back of you," the old woman’s voice commanded.

Clara followed the sound into a small back parlor that looked out through a high, barred casement into a narrow brick courtyard. A small fire burned in the grate—not coal, which made a yellow, greasy smoke, but square turf-sods that gave off an earthy, dry heat that Clara felt instantly in her shins.

Mother Thimble was already out of her cloak. Without it, she appeared even shorter and wider than she had in the Matron’s parlor. She wore a bodice of stiff black fustian, completely unadorned except for a row of twelve small, white bone buttons that ran from her collar to her waistband with the regularity of teeth in a saw. At her side hung a heavy leather châtelaine from which dangled an assortment of implements that made Clara’s eyes widen: three pairs of shears of varying curves, a brass awl with a polished boxwood handle, a small horn grease-pot, and an enormous, pitted iron thimble that looked as though it could have been used to measure brandy in a low tavern.

"The cloak," Mother Thimble said, pointing toward a peg behind the parlor door. "Hang it by the collar-stay, not the hood. If you hang it by the hood, the weight stretches the grain and then the wind gets into the shoulder-blades."

Clara took the heavy broadcloth. It was surprisingly stiff, as if the lining had been reinforced with canvas or thin slats of whalebone, and it carried that same cold, metallic smell she had noticed at St. Jude’s. She hung it carefully on the peg, smoothing down the hem so it did not curl.

"Well," Mother Thimble said, seating herself in a low-backed armchair by the hearth. The chair had no cushions, only a sheepskin pelt that had lost most of its fleece along the seat-rail. "You’ve seen the street."

"It’s very quiet," Clara said, her fingers still hovering near her own pin.

"It is when the work goes right," the woman said sourly. "When the work goes wrong, it’s noisy enough to wake the drowners in the mud. Sit down, girl. Not on the basket—that has pig-bristle in it and it’ll stick through your skirts till next winter. Take the stool."

Clara sat on the three-legged stool near the hearth. The wood was scrubbed white and smooth as an eggshell.

"Do you know what this house is?" Mother Thimble asked, leaning forward with her elbows on her knees. Her thumbs, Clara noticed, were completely flat at the tips, like the spatulas painters use for mixing colors.

"A shop, ma'am," Clara said. "The sign says repairs."

"Repairs," Mother Thimble repeated, with a short, dry snort that might have been a laugh if there had been any humor in it. "Aye. The world has a deal of holes in it, Clara Finch, and most of them are small enough to fall through before you know you’re slipping. You’ve lived in an orphanage fourteen years. You think houses stay upright because of the lime in the brick?"

Clara blinked. "I suppose so. And the oak-beams."

"The oak rots," Mother Thimble said flatly. "The lime turns to powder every time the November frost gets behind the pointing. A town is nothing but a million tons of dirt and wood and iron that would rather be lying flat in the grass if it had its own choice. Things want to come undone. It’s their natural state. Thread wants to untwist; nails want to back out of the beam; iron wants to turn red and crumble into the ditch. Everything that men build is an argument against the ground."

She reached into the small leather bag that hung from her châtelaine and took out three objects, laying them one by one on the round table between them.

The first was a flat disc of lead, rough-edged and grey, with four ragged holes punched through it with a square nail.

The second was a small button of polished boxwood, carved with six spiral grooves that curved from the center to the rim like the vanes of a mill-wheel.

The third was a simple, circular piece of blue glass, no larger than a gooseberry, with a loop of thin copper wire embedded into its back.

"Tell me what those are," she said.

Clara leaned forward. She did not touch them—there was an expression in Mother Thimble’s pale hazel eyes that suggested uninvited fingers might meet the business end of the brass awl—but she looked at them until the image seemed to burn into her retinas through the crown-glass light.

The lead one looked like it had been salvaged from an old roof-gutter. It was heavy, dull, and had a small greasy smear of soot along its lower rim.

"That one’s for something heavy," Clara said slowly. "Something that doesn't want to move once it’s sat down. A cellar-door, maybe. Or a wagon-tail."

"The second?" Mother Thimble’s voice was lower now, steady as the tick of a clock.

"The wood one... it has a turn in it," Clara muttered, her head tilting slightly. "The grain doesn't go straight across. The man who carved it followed the knot. It’s for something that turns around and around without coming off. A water-spout. Or a wheel-hub."

"And the glass?"

Clara hesitated. The blue disc was cold-looking, perfectly clear, like a drop of sea-water frozen on a winter morning. But when she squinted at the center, where the copper wire was twisted into the back, she could see a faint, iridescent film, like the oil that sits on top of ditch-water in the summer heat.

"It isn't for holding cloth," Clara said, looking up into the woman’s flat eyes. "It’s too smooth. The thread would slip off the shoulder. It’s for looking through. Or for keeping something from being seen."

Mother Thimble remained silent for so long that Clara began to wonder if she had said something stupid enough to warrant being sent straight back to the caraway biscuits and Sister Agnes’s ruler. A log of turf broke in the hearth, sending up a small, pungent shower of red sparks that died on the stone hearth.

"You’ve got the sight for the grain," the old woman said at last, her hand sweeping out to scoop the three buttons back into her bag with a single, practiced motion. "Most of them only see the color. They think a red coat wants a red button, and a black coat wants horn. Idiots, every mother’s son of them. They think a coat stays on their back because the cloth is cut right."

She stood up and went to the dresser, where a brown stoneware pitcher and two horn mugs stood between a basket of salt and a crock of pickled walnuts. She poured two measures of thin, sour small-beer and pushed one toward Clara.

"Drink that. It’s better than the pump-water, which is half bilge from the lime-pits. Then we’ll go down to the cellar."

"What's in the cellar?" Clara asked, taking the mug. The beer was bitter and tasted faintly of iron casks, but it was cold and wet, and her throat had been dry since the bridge.

"The foundation," Mother Thimble said. "Number Seven wasn't built by a mason, Clara. It was fastened down. Bramble Street doesn't have stones under it like the high town; it’s built on the mud of the old salt-marsh. Fifty feet of silt and dead rushes before you hit anything harder than porridge. If it weren't for the work done in this shop, every house from the turnstile to the slipway would have listed into the ditch before King George took the throne."

She took a long draught from her own mug and wiped her mouth with the back of her square hand.

"The people on this street don't know it, of course," she continued, her voice taking on that flat, rhythmic quality that Clara had noticed in the Matron’s parlor. "They think Mr. Cloutier’s chimney draws because he has a patent cowl on the pot. They think the cellar at the cooperage stays dry because the ditch was dug deep. They think Mrs. Gable’s front door doesn't stick in the August humidity because her nephew is a clever lad with a jack-plane."

She looked at Clara with a hard, sharp squint.

"It isn't the cowl. It isn't the ditch. And it certainly isn't the nephew, who has thumbs like green bananas and couldn't plane a deal board flat if his salvation depended on the shavings. It’s the three-hole brass on Cloutier’s hearth-beam. It’s the double-shanked lead in the cooper’s sump. It’s the horn toggle Mrs. Gable keeps behind her door-post."

Clara stared into her small-beer. The idea was absurd, of course. Sister Agnes had spent eight years explaining that the world was governed by Divine Providence and the Board of Guardians, both of whom were notoriously strict about expenditures and took a dim view of girls who entertained notions about inanimate objects.

Yet Clara remembered the river-horn button in her pocket. She had only touched it three times since Mother Thimble had dropped it into her hand, but each time her fingers found it, the cold ache in her right ankle—the one that had bothered her ever since she fell down the coal-hole two winters ago—had seemed to ease, as if someone had bound the joint with a warm, tight woolen wrap.

"Why do you need me?" Clara asked.

Mother Thimble picked up her shears from the table, turning them over and over through her fingers with a dexterity that was almost frightening. The steel clicked rhythmically against the brass rings of her châtelaine.

"Because my eyes are going," she said, without the slightest change in her voice. "Not the sight for the bread or the street—I can still see a thief thirty yards off through the drizzle—but the eye for the twist. When the silk gets finer than a hair from a horse’s tail, it blurs. A knot that’s three inches out of true is worse than no knot at all; it’s an invitation to the tear."

She leaned closer. Clara could smell the tallow on her skin, cold and animal.

"And there’s another thing," Mother Thimble said, dropping her voice until it was hardly louder than the turf-smoke rising up the chimney. "Things have been loosening."

"Loosening?"

"A loop here. A shank there. Old work that should have held fifty years after I was in the lime-pit, coming untied in the night. It started before Michaelmas with the gate-iron at the lane-end. Then the baker’s chimney started smoking black into his dough-troughs, though the flue-button had three coats of pitch on it and hadn't moved since the year of the frost."

She stopped, her hand closing tightly around the shears until the steel dug into her thumb-flesh.

"Somebody is pulling the ends, Clara Finch. Somebody who knows where the stitches were put in."

Before Clara could answer, a bell rang somewhere above their heads. It was not a church bell, nor the tinny hand-bell the Sister used to summon the girls to their prayers, but a single, heavy clink, like a brass thimble dropped onto a flagstone.

Mother Thimble stood up instantly, her face settling back into its customary mask of weathered wood.

"The shop," she said, nodding toward the low door that led off the passage toward the front of the house. "That’ll be Mrs. Garrow from the tallow-wharf. Her corset-stay is made of whalebone that was split against the grain, and she expects me to keep her from bursting through her stays every time she has salt pork for dinner."

She turned at the threshold and looked back at Clara, who was still sitting on the three-legged stool with her horn mug half-empty.

"Leave the bundle," she said. "The room at the top of the garret stairs is yours. It has a flock mattress and a bolster that doesn't leak much straw. If the roof drips on the pillow, move the bed three inches to the left. Don't touch the spools on the window-board, don't light a candle after the nine-bell, and if you hear something scratching inside the wainscot, don't put your fingers through the knot-hole. It isn't a mouse, and it doesn't like salt."

She vanished into the dark hallway, leaving the door slightly ajar.

Clara sat alone in the parlor for several minutes, listening to the small sounds of Number Seven. Through the floorboards, she could hear a faint, regular vibration—a deep, muffled thump-clack, thump-clack that sounded like an enormous loom working somewhere down in the foundations of the house, though the motion was too slow for any linen-frame she had ever seen.

From the front shop came the high, shrill complaints of a customer, followed by the dry, measured rumble of Mother Thimble’s voice, which seemed to carry through the timber walls with the weight of an iron rod.

Clara reached down into her apron pocket and took out the cider-colored horn button.

She held it up to the grey light that filtered through the barred casement. In the dimness of the parlor, the two holes through the center looked less like drill-marks and more like the pupils of two very small, very attentive eyes.

"Three rows of linen tape," Clara whispered to the empty room, her thumb testing the smooth, warm bevel of the rim. "And a wax-thread backstitch. Otherwise the front’ll come off the first time you lean against the counter."

The button did not answer, but as she slid it back into the calico pocket, it felt slightly warmer than it had a moment before, like an ember covered over with dry grey ash, waiting for the draft to pick up from the river.
