The mist did not rise from the river; it seemed to sweat directly from the millstone grit of the valley walls, a cold, greasy vapor that smelled of peat, wet coal, and the impending rot of autumn. It was October of the year 1847, and the Great Skelmer Gorge was no longer a sanctuary for the owls and the red deer. It had been invaded by three thousand men, ten thousand tons of timber, and an insatiable appetite for stone. Across the deep chasm, where the River Skelmer twisted like a bruised ribbon, the skeletal ribs of the great viaduct rose into the gray sky, a monstrous monument to the age of steam.

Upon the highest tier of the timber staging stood Silas Vance, the resident engineer for the Great Northern and Western Railway Company. He was twenty-eight years old, but the dampness of the Yorkshire dales had already settled into his knees, and his boots were permanently caked with a gray slurry of lime mortar and crushed shale. In his hand, he held a brass-bound pocket transit, though there was little use for it today. The fog was so thick that the far side of the valley, barely four hundred yards away, had been completely erased, leaving only the immense, half-formed masonry piers to emerge from the void like the teeth of some buried leviathan.

"She’s shifting again, Mr. Vance," said his foreman, Jesse Clowes, whose voice was a gravelly rasp born of forty years in quarries and damp tunnels. Clowes stood on the narrow planking beside him, his wool coat patched with pieces of sailcloth, a clay pipe unlit between his yellow teeth. "Arch Number Four. The centring is groaning like an old woman’s joints when the wind catches it. I don’t like the sound of the timber. It’s too green, I tell you. The contractor is buying cheap larch from the lowlands, and it hasn't the strength to hold the weight of the crown stones."

Silas adjusted his wool muffler, his knuckles white against his brass instrument. "The Board won't hear of delays, Jesse. We are already six months behind schedule, and the London directors are screaming about the winter frost. If we don’t close the key-stones on the first four arches before the hard freeze sets in, the mortar will disintegrate by spring, and we shall have forty thousand pounds of masonry sliding into the river."

Below them, the gorge was a cauldron of chaotic noise. The sharp, rhythmic clink-clink-clink of the masons’ chisels echoed off the wet rock faces, punctuated by the harsh shouts of the mule drivers and the hiss of a portable steam winch at the base of Pier Three. But above all other sounds was the thudding heartbeat of the piling engines, driving heavy iron-shod timber baulks deep into the treacherous blue clay of the riverbed. It was a brutal, relentless rhythm that seemed to shake the very marrow of Silas's bones.

A sudden, sharp crack—like the report of a pistol—shattered the damp air.

Both men froze. Silas looked down through the gaps in the wet scaffolding planks. Two hundred feet below, the river looked like a thread of gray slate, its banks cluttered with the timber hovels of the navvies’ shantytown, a lawless settlement known locally as Jericho.

"That wasn’t a mason's hammer," Silas whispered, his heart hammering against his ribs.

"No," Clowes muttered, already turning toward the wooden ladder that descended into the mist. "That’s the main diagonal on the north trestle. The larch is splitting under the strain."

They descended together, climbing down the slick, wet rungs with the practiced ease of sailors, though Silas felt every foot of the drop in the pit of his stomach. A single slip on these greasy timbers meant a long, silent fall into the rocks below; the company did not provide safety ropes, and a man who lost his footing was simply replaced by another from the hungry crowds waiting at the hiring gates each Monday morning.

As they reached the lower platform of Arch Four, the air grew thicker with the stench of coal smoke and the sour, milky smell of fresh lime. Here, a gang of twenty navvies—men with chests like barrels and faces blackened by gunpowder and soot—stood in a silent semicircle. They were staring at a massive diagonal timber, eighteen inches square, that braced the great wooden framework supporting the unfinished stone arch. A long, jagged splinter of wood, several feet long, had peeled away from the heart of the beam, weeping sap onto the muddy platform below.

"Back away from her!" Clowes roared, shoving his way through the crowd of workmen. "Are you lot soft in the head? If that trestle gives, the whole platform goes into the river, and you'll go with it."

The men did not run. They were tired, their muscles stiff from twelve hours of shoveling and lifting, and they possessed the strange, fatalistic indifference of men who lived with death as a daily workplace acquaintance. One of them, a broad-shouldered Irishman named Rory Doyle, spat a stream of dark tobacco juice onto the splitting timber.

"She’s hungry today, Mr. Vance," Doyle said, looking not at the splintered wood, but at the massive stone pier beside them. The pier was a hollow shell of dressed ashlar blocks, filled with a core of rubble and mortar. "The viaduct’s always hungry when the mist comes down. She’s looking for her tithe."

"Don't talk rot, Doyle," Silas said, though he could not help but look at the great dark opening of the hollow pier. To save on stone and weight, the design called for the lower sections of the piers to be built with internal chambers, empty spaces that would later be sealed and forgotten. "The timber is defective, that’s all. We will replace it with a double-baulk of Baltic fir from the depot."

"We’ve no Baltic fir left in the yard, sir," Clowes said quietly. "The last of it was used to timber the head-heading of the West Tunnel last week. There’s nothing left but the local green larch."

Silas felt a cold drop of water slide down the back of his neck. He stepped closer to the splitting beam, his boots crunching on the loose grit. He could hear the wood creaking, a low, vibrating hum that traveled through the soles of his feet. The weight of the stone arch above them—hundreds of tons of hand-carved gritstone—was pressing down on this single, fragile point of support. If the timber collapsed before the mortar cured and the keystone was dropped into place, the entire arch would buckle inward, dragging the adjacent piers down in a catastrophic chain reaction.

"We must jack it up," Silas ordered, trying to keep his voice steady. "Bring the hydraulic jacks from the smithy. We’ll place three of them under the transom and relieve the pressure on the split beam. Then we’ll sister it with three-inch iron plates and bolt them through."

"The jacks are at the north tunnel, Mr. Vance," Doyle said, his voice flat. "The contractor took them yesterday to lift the roof-shield after the cave-in."

"Then send a mule cart to fetch them!" Silas snapped. "Immediately. If we don’t secure this arch before the shift ends, we’ll be digging our work out of the river tomorrow morning."

Doyle didn't move. He looked at the other navvies, who stood like statues in the swirling fog. There was a sullen, stubborn resistance in their eyes that Silas had seen before. These men were paid by the yard of earth moved or the number of stones laid; they had no love for the railway company, and still less for the young, book-learned engineers who told them how to risk their lives.

"The men won't work under that arch while the timber’s singing, sir," Doyle said. "It’s bad luck. We’ve already lost three men this month—one to the blast in the cutting, and two who took the long step off Pier Two. The lads are saying the viaduct won't stand until she has a man in every pier."

"That is superstitious nonsense!" Silas said, his voice rising in anger. "You are Yorkshiremen and Irishmen, not savages. The stone stands because of mathematics and the strength of the mortar, not because of some pagan blood-sacrifice. Get those jacks, Doyle, or I’ll have your name off the time-book before the sun sets."

Doyle shrugged, a slow, insolent gesture, but he turned and spoke to two of the younger boys, who vanished into the gray gloom toward the north end of the gorge.

Silas stepped closer to the great stone pier, trying to ignore the prickle of unease that Doyle’s words had left in his mind. He placed his hand against the cold, damp face of the ashlar wall. The stone was cold—colder than the air around it—and it seemed to vibrate with a faint, rhythmic thrumming that was not entirely in time with the distant piling engines. He leaned his head closer, his ear nearly touching the wet gritstone.

For a brief, absurd moment, he thought he heard a sound from within the hollow core of the pier.

It was not the sound of settling rubble or the dripping of water. It was a soft, dry scratching, like the claws of a nesting bird, or perhaps the fingernails of a man scraping against the rough interior face of the stone.

He drew back quickly, his heart racing. He looked at Clowes, but the old foreman was busy examining the split in the larch timber with his pocketknife, muttering curses under his breath.

"Jesse," Silas said, his voice lower now. "Did you hear that?"

"Hear what, sir? Only the wind in the stays and this bloody timber crying for mercy."

"Within the pier," Silas said, pointing to the narrow inspection slit in the masonry—a temporary opening left to allow the engineers to check the alignment of the internal core before it was sealed. "It sounded like... something moving."

Clowes stopped his carving and looked at the slit, then back at Silas. His expression was solemn, devoid of the skepticism Silas had expected. "There’s plenty of things moving in the gorge, Mr. Vance. Mostly rats. The navvies leave their scraps everywhere, and the beasts find their way into the hollows. Best not to listen too closely to the stones. A man can go mad in this fog if he starts trying to translate what the masonry is saying."

Before Silas could answer, a loud shout arose from the direction of the north abutment. It was a high, panicked cry that cut through the low rumble of the valley.

"Heads up! Below there!"

A terrible, rending sound echoed from the fog above them. It was followed by the crash of falling timber and the metallic scream of breaking iron chains. Silas looked up, but the mist showed nothing but a swirling gray vortex.

"Run!" Clowes yelled, grabbing Silas by the collar of his coat and hauling him backward toward the safety of the rocky ledge where the arch met the valley wall.

The navvies scrambled like rats, throwing themselves into the shallow crevices of the rock face. A split second later, a massive pine scaffold pole, sixty feet long and thick as a man's waist, came hurtling out of the sky like a giant’s spear. It struck the platform where they had been standing just moments before, smashing through the heavy larch planks as if they were dry twigs.

The platform collapsed with a sickening roar. The splitting diagonal timber gave way entirely, and with it went several tons of unfinished stone voussoirs from the arch above. The masonry fell in a slow, thunderous cascade, disappearing into the mist and striking the riverbed below with a sound that shook the entire gorge.

For several minutes, Silas could hear nothing but the ringing in his ears and the sound of his own ragged breathing. The air was thick with the choking dust of shattered lime mortar and the smell of freshly splintered wood. He lay on his stomach on the cold rock ledge, his hands over his head, waiting for the rest of the bridge to come down upon them.

But the great piers held. The massive stone pillars stood rigid in the gloom, unshaken by the destruction of the timberwork around them.

Silas slowly raised his head. The platform was gone. Where he, Clowes, and the navvies had been standing, there was now only a yawning gap of gray fog, with the shattered ends of the remaining timbers dangling over the abyss.

"Jesse?" Silas called out, his voice hoarse from the dust. "Jesse, are you whole?"

A groan from a nearby niche in the rock answered him. Clowes crawled out, his face covered in gray dust, looking like a ghost risen from the earth. "I'm here, sir. Though I think my ribs have had a disagreement with a piece of iron-work."

The navvies were slowly emerging from their shelters, shaking the white lime dust from their hair and clothes. Amazingly, none of them appeared to be seriously injured, though several were bleeding from minor cuts.

"Is everyone accounted for?" Silas asked, struggling to his feet and wiping his spectacles on his sleeve.

Rory Doyle walked to the edge of the broken platform, looking down into the gray void where the timbers had disappeared. He did not look frightened; his face was grimly satisfied.

"We’re all here, Mr. Vance," Doyle said, turning back to face him. "But the wind-lass boy from the north pier says different. He says one of the quarrymen was on the upper staging when the chain snapped."

"Who?" Silas asked, a cold dread settling in his stomach.

"Young Billy Cobb," Doyle said. "Only sixteen. He was working the lime-bucket. He went down with the stone."

Silas walked to the edge of the rock ledge, looking down into the swirling mist of the gorge. The River Skelmer was invisible, buried beneath the thick blanket of vapor, but he could hear the distant, muffled roar of its waters, rushing southward toward the sea, carrying with it the dirt, the stone, and the secrets of the valley.

"We must get a search party down to the riverbed," Silas said, his voice trembling slightly. "Perhaps he survived the fall. The water is deep under Arch Four."

"He didn't survive, sir," Doyle said quietly, his voice carrying a strange, heavy authority that silenced the other men. "Nobody survives a fall from the top tier. The river has him now. Or the stone does."

Silas looked at the massive, dark face of Pier Four. The stone blocks looked black in the damp mist, their mortar joints bleeding white lines of lime down the face of the masonry. The inspection slit was still there, a narrow, dark mouth in the side of the pillar, completely silent now.

The mist seemed to press closer, swallowing the ruins of the scaffolding and drawing a gray curtain over the gorge. Silas knew that the work would not stop. Tomorrow, new timbers would be hauled down the steep tracks, a new platform would be built, and another gang of hungry men would take their places on the narrow planks. The railway must go through. The Great Northern and Western would have its viaduct, no matter how many men it swallowed.

The paymaster’s hut stood three hundred yards downstream from the works, teetering on a bank of black mud that smelled permanently of boiled cabbage and wet mules. It was constructed of tarred felt nailed over green pine planks, an architectural style that Silas Vance had come to realize was entirely peculiar to the railway age: cheap, portable, and utterly incapable of keeping out the damp. Within, a cast-iron stove glowed cherry-red around its lower seam, threatening to set the floorboards ablaze while failing entirely to warm the corners of the room, where mold grew in thick, velvety rings.

At a high desk made from two salvaged casks and an unplaned deal board sat Barnaby Finch, the clerk sent out by the Leeds committee. Finch was an ink-stained bachelor of fifty with the pallor of a turnip and the sharp, nervous eyes of a terrier that expected to be kicked. He wore black alpaca sleeves to preserve his cuffs, and his fingers were dyed an indelible purple from the indelible ink of the company registers.

"A boy named Cobb," Silas said, leaning his dripping oilskin hat against the corner of the desk. He held his raw, scraped knuckles toward the stove. "William Cobb. The windlass crew claims he was on the north stagings when the larch gave way."

Finch didn't reach for a fresh sheet of paper. Instead, he dipped his steel nib into the well, tapped the excess onto the rim with three dry, metallic clicks, and drew a thick, ruled line across the middle of a ledger bound in calfskin. "Cobb. William. No middle initial recorded. Did he leave any boots behind in the huts?"

"I didn't inquire after his boots, Finch. He fell two hundred cubits into the torrent. The boy is dead."

"The company cares about the boots, Mr. Vance," Finch said without looking up, his pen scratching rhythmically across the fibrous blue paper. "Boots issued against wages are recoverable property. If his mates took them from his palliasse before the shift ended, that’s four shillings and sixpence the subcontractor owes to the central office. We can’t write off leather just because the river is high."

"Write him down as dead," Silas said, his voice dropping into that quiet, hard register he used when his patience wore down to the gray grit.

"I cannot do that," Finch replied mildly. He blew on the ink, then turned the ledger toward Silas so that the engineer could read the column headings. They were ruled in neat carmine lines: Name, Parish of Origin, Gang Number, Stoppages for Provisions, Tallow and Beer, Balance Carried Forward.

"Why can you not?"

"Because there is no body, Mr. Vance. The Board in London has a very clear protocol regarding casualty compensations. A pound toward burial expenses is only paid out upon production of a remains, certified by a surgeon or a churchwarden. If every lad who slipped off a trestle or walked away to work the harvest in Lincolnshire were listed as deceased, the directors would be bankrupt by Christmas. He is entered as Absent Without Leave. His balance of three shillings and twopence is forfeit to the general contingency fund."

"The boy was crushed under five tons of stone before he even hit the water," Silas said. "Jesse Clowes saw the timber take the staging out from under him. He isn't walking to Lincolnshire."

"Perhaps he is, perhaps he isn't," Finch said, turning the page. "Men walk away from Jericho every Saturday night. Some go over the moors toward the Lancaster line. Some go into the coal pits at Barnsley. Some go into the ground. Unless the local constable drags him out of the shallows at Skelmer Pool and brings him up the hill in a barrow, William Cobb is simply an open account that failed to report for his tally."

Silas stared at the open page. Down the left margin, inked in Finch’s meticulous copperplate hand, were dozens of names. Nearly half of them were crossed through with a single stroke of red ink, marked with the abbreviation A.W.O.L. or Gone to Settle.

"How many have left the works since the foundation stone was laid in May?" Silas asked.

"Departed or discharged?"

"Missing."

Finch leaned back, his small eyes blinking behind square-framed spectacles. "The turnover among the navigators is eighty per cent per quarter, Mr. Vance. You know that as well as I. They are migratory beasts. They drift in from the fens, from Connemara, from the Scottish borders. They work until they have twenty shillings in their pocket or until they break a wrist, and then they vanish. They are not like town clerks. They don't leave cards."

"Show me the August ledger," Silas said.

Finch hesitated, his quill hovering above the inkpot like a poised dart. "The August books are balanced and sealed for the auditors."

"Open them."

With a small, theatrical sigh that expressed the profound martyrdom of all minor bureaucrats, Finch reached down into a zinc-lined chest behind his stool and hauled out an older volume, bound in buckram that was already buckled and warped by the damp river air. He laid it flat with an audible slap and flipped the leaves back to the weeks of late summer, when the heat in the valley had turned the water in the shallows green and the men were dying of the bloody flux two at a time in the turf shanties.

Silas leaned over the clerk’s shoulder. His eyes, trained to find discrepancies in chains and links of land measurement, scanned the neat columns.

There were names he remembered. Big Thomas, the Cornish miner who had set the charges for the foundation trench of Pier Three. Michael Burke, the quiet carter who could back a four-horse team onto an eight-foot ledge without blinking. James Miller, the young mason who had brought his wife and two daughters up from Nottingham.

Next to Big Thomas: A.W.O.L. Aug 12. Left pick and shovel; balance forfeit. Next to Michael Burke: Departed without notice Aug 19. Two carts unclaimed. Next to James Miller: Left works Aug 24.

"Miller didn't leave," Silas murmured, his finger tapping the dry paper. "Miller had a four-room sod hut behind the lime kilns. He had two young girls with the whooping cough. He told me himself he wouldn't move until the viaduct reached the seventh arch, because the air on the moor was better for the children's lungs than the smoke in Nottingham."

"And yet," Finch said, pointing with the dry end of his pen, "he isn't here. His tools were sold at the Saturday auction to cover his arrears at the company canteen. Eight shillings for his chisels, five for his mallets. Mrs. Miller took the coach to Leeds three days later. The company was generous enough not to sue her for the remainder of his account."

"Did anyone speak to her?"

"The canteen manager did, I expect. She took her bundles and went. People don't linger in Jericho, Mr. Vance, once their breadwinner takes a notion to see the world."

"Men don't abandon four pounds' worth of English tool-steel to go tramp the roads," Silas said. "A mason's tools are his living. A man will pawn his coat, he'll pawn his boots, he'll even pawn his bible, but he won't leave his chisels unless his hands are cold."

Finch dipped his pen again. "You have a very romantic view of the common laborer, Mr. Vance. Most of them are scoundrels who would murder their own grandmothers for a gallon of gin, and half of them are running from parish constables in the south. When a bailiff shows his face at the head of the valley, three gangs melt away into the gorse before noon. If they leave their iron behind, it’s because iron is heavy to run with."

Silas didn't answer. He turned the pages himself, his boots leaving dark water marks on the floorboards as he shifted his weight.

The numbers didn't make sense. In any major civil work—a canal cutting, an ironworks, a dockyard—there was an expected rate of waste. Men broke legs under shifting wagons; they lost eyes to flying chips from the scappling hammers; they caught the swamp-fevers and died in their cots. But on the Great Skelmer Viaduct, the ledger recorded an astonishing lack of burials. According to Finch’s neat figures, only five men had died by misadventure since the first sod was turned fifteen months ago.

Five men dead.

And seventy-four men listed as having simply walked into the mist, leaving their coats, their pay, and their tools behind them.

"Where is the hospital tent?" Silas asked suddenly.

"Taken down two weeks ago," Finch said smoothly. "Mr. Harbottle, the contractor, decided it was an unnecessary charge upon the medical fund. The sick are now sent by cart to the workhouse infirmary at Keighley."

"And the ones who don't survive the cart ride?"

"The parish overseer deals with them. It doesn't appear on our balance sheet." Finch closed the ledger with a soft, final thud. "Was there anything else, Mr. Vance? I have forty-eight subsistence vouchers to check before the lamps are put out. The Board has noticed an irregular consumption of candles in the carpenter's shop, and I am instructed to deduct the difference from the master carpenter’s monthly allowance."

Silas looked at the little clerk. In the dim, orange glow of the stove, Finch’s skin seemed more than ever like parchment, as though he had lived so long among columns of figures that his veins ran with nothing but iron-gall ink.

"William Cobb's mother lives in Skipton," Silas said. "I saw her once, when he signed his articles. She had one eye and a crippled foot. She won't have four shillings and sixpence to buy back his boots."

"Then she should have taught him to keep his footing on the staging," Finch said, not looking up as he uncorked a jar of pounce. "The railway does not run on sentiment, Mr. Vance. It runs on seven-and-a-half-percent preference shares. Good evening to you."

Silas pulled his wet hat down over his forehead and stepped out into the gorge.

Outside, the darkness had come down completely, swallowing the upper half of the valley in a blackness so dense that the great viaduct was invisible except for the scattered braziers burning on its lower platforms. They hung in the night like suspended coals, their red glare painting the dripping rock walls of the gorge with long, bleeding streaks.

The wind had shifted from the east, bringing with it the sulfurous tang of the lime kilns and the dull, persistent sound of the river rushing through the narrow gap between Piers Three and Four. The water was higher now; the rain on the moors five miles north was funneling down the gorge, turning the river into a brown, frothing monster that tore at the temporary piling and carried dead sheep and sheared timbers down toward the low country.

Silas walked along the tram-road that ran along the valley floor. The iron rails, spiked hastily into rough pine sleepers, were slick with mud. Every few paces, he had to step aside into the weeds to let a gang of night-shift earth-movers pass. They moved like shadows, their wool jackets steaming with sweat, their faces invisible beneath the low brims of their caps. None of them spoke. The cheerful, brutal noise of the day shift had vanished, replaced by the grim, mechanical labor of men who worked under the threat of the sack.

At the base of Pier Four, he stopped.

The scaffolding above was a tangle of black lines against the leaden sky, like the web of a monstrous spider that had died in the winter. Below, on the bank, a single brazier sat on an upturned oil barrel, attended by Rory Doyle. The Irishman was sitting on a block of millstone grit, a thick ash stick between his knees, staring into the embers.

"You're late down from the books, Mr. Vance," Doyle said, not turning his head. He seemed to recognize Silas by the sound of his stride on the iron rails.

"The clerk is a hard man to convince," Silas said, stepping up to the warmth of the brazier. His trousers were stiff with cold mud around the ankles. "He says young Cobb has walked to Lincolnshire."

Doyle gave a short, dry bark of laughter that ended in a cough. "Aye. That’ll be it. He’s taking the air in the fens. Him and the others."

"What others, Doyle?"

The Irishman looked up then. His face was a map of old scars, the skin around his eyes puckered from an old blast-powder flare-up in the Box Tunnel ten years before. "You're a gentleman, Mr. Vance. You've got an uncle in the company offices in London and a degree from the college in Durham. You think things happen because a man with a gold watch signs an order on white paper."

"I think things happen because men work, or because they make mistakes," Silas countered.

"Mistakes," Doyle repeated, rolling the word in his mouth like a piece of sour fruit. "That's what they call it when a chain parts or a heading caves in. But the stone doesn't make mistakes, Mr. Vance. You can test it with your little levels and your brass sights all day long, but this gorge has been here since the flood, and it doesn't want your iron road running across its mouth."

"The stone is gritstone, Doyle. It has a compressive strength of eight hundred pounds to the square inch. It doesn't want anything. It doesn't have a mind."

Doyle stood up, towering over the young engineer. He was not a tall man, but he was wide—built with the heavy, sloping shoulders of a ditcher who had spent thirty years moving mountains one spadeful at a time. He pointed with his ash stick toward the base of the pier.

The ashlar blocks at the water level were four feet long, two feet high, joined by mortar so fresh it still had the gray, greasy look of lard. The temporary opening—the inspection hole Silas had peered into that afternoon—was barely two feet wide, a narrow black wound in the side of the stone tower.

"Put your ear to it now," Doyle said.

"I have work to do at the depot, Doyle."

"Put your ear to it," the navvy repeated, his voice dropping into that low, flat growl that brook no contradiction from men who valued their teeth. "Listen to the mortar setting."

Silas hesitated, but the strange, cold curiosity that had haunted him all afternoon pulled him forward. He stepped through the mud, his boots sinking to the lacing, until he stood against the cold flank of Pier Four. The smell was intense here—the alkaline, dead-bone smell of the slaked lime mixed with the river weeds and the damp sulfur from the coal fires.

He leaned in. He did not touch the stone with his hands this time; he simply brought his ear within two inches of the open slit.

At first, there was only the wind—the hollow, flute-like whistle of the draft being sucked into the interior core of the pier by the chimney effect of the tall shaft. But then, underneath the whistle, he heard it again.

It was not a scraping this time.

It was a slow, wet slump. The sound of something heavy settling into deep, stiff mud. A thick, sucking sound, like a cow pulling its leg out of a peat hag.

And then, clear and distinct above the lap of the river against the footings, came the sound of three sharp, rhythmic raps.

Tock. Tock. Tock.

It was the precise, ringing sound of a mason’s iron mallet striking the interior face of the stone from within.

Silas jerked back so violently his hat fell into the mud. He grabbed his pocket transit with one hand, his heart hammering against his ribs like an engine with a broken governor. "There is someone inside that core," he whispered, his breath coming in white clouds against the black stone.

Doyle didn't move from his brazier. He picked up a lump of coal with his bare, calloused hand and tossed it into the red embers. It hissed, split, and caught fire with a spurt of greasy yellow flame.

"There was forty yards of rubble dropped into that pier this afternoon, Mr. Vance," Doyle said quietly. "Brought down from the high cutting in the tip-carts. Six carts of ballast, four carts of lime, and three carts of shale from the black seam. If there’s someone inside, he’s got ten tons of rock sitting on his boots."

"We have to open it," Silas said, lunging toward the stack of picks leaning against the platform legs. "Fetch the gang from the smithy! We can clear the slit before the lime cures—"

Doyle’s arm shot out, his heavy fingers clamping down on Silas’s forearm with the force of an iron clamp. The navvy's face was completely expressionless in the firelight.

"You won't touch that stone, Mr. Vance."

"Are you insane? There is a man alive in there!"

"There was a man," Doyle said. "Maybe two hours ago. Maybe yesterday. But if you take a crowbar to that pier now, the arch above will drop three inches before midnight. The whole south centering will skew, and the company will lose thirty thousand pounds. Do you think Mr. Harbottle will thank you for that? Do you think the London directors will give you another line to build?"

"I don't care about the company's money—"

"I do," Doyle interrupted, his grip tightening until Silas felt the bone in his wrist groan. "Because if this work stops, the contractor goes bankrupt, the canteen closes, and two thousand men spend the winter starving on the moors with no bread and no beer. One lad from Skipton doesn't weigh against two thousand, Mr. Vance. That’s the arithmetic of the line. Your books in the office don't show it, but that's how the track gets laid."

Silas struggled against the grip, but he was a creature of ink and paper compared to the man who held him. He looked from Doyle’s scarred, pitiless face back to the dark mouth in the stone.

The tapping had stopped.

There was only the sound of the river now, and the steady, indifferent drip of water from the upper stagings, falling two hundred feet through the mist to splash upon the stones below.

"Who was it?" Silas asked, his voice shaking. "It wasn't young Cobb. The tapping was too steady. Cobb didn't have a mason's hammer."

Doyle slowly released Silas’s arm. He wiped his hand on his trousers, turned back to the brazier, and spat into the coals.

"James Miller was a good hand with the chisel," Doyle said, his voice so low Silas could barely hear it over the roar of the Skelmer. "He could face three yards of stone a day and never leave a feather-edge. But he had a sharp tongue on him when the beer was sour, and he had a notion that the contractor was cheating the gangs on the yardage."

"Miller went to Nottingham," Silas said, though he knew, with a sudden, sick certainty, that the words were hollow. "His wife took the coach."

"Aye," Doyle said, looking up into the swirling gray mist that hung between the half-formed arches. "The coach to Leeds. That's what the clerk wrote down, isn't it? And Finch is a very particular man about his books. If it’s in the ledger, Mr. Vance, it must be the gospel truth."
