The sea did not so much yield Black Isle to the world as lend it out twice a day, reluctantly, between the tides.

When the gray waters of the Firth receded, they unveiled a sunken spine of slick cobbles, crushed mussel shells, and packed black mud known simply as the Crossing. It ran for three-quarters of a mile from the salt marshes of the mainland to the sharp granite cliffs of the island. For six hours, men, horses, and laden carts could scrape across the dripping track, their iron rims grinding against the stones while the gulls screamed overhead. Then the waters would gather themselves, black and icy, and sweep back over the causeway, swallowing the road under twelve feet of foam until the moon called them off again.

Luke Vance stood near the northern abutment, wrapping a strip of greasy wool around his palm where a patch of gorse had torn his skin. He was twenty-four, possessed of long legs, a narrow nose that smelled rain hours before it arrived, and the perpetual mud-splatters of a man who spent his mornings bent over tidal pools. As assistant to Master Gidney—the island’s only licensed apothecary—Luke’s duties frequently required him to scramble among the slippery rocks before the tide drowned his harvest.

Today, he had two wicker hampers slung over his shoulders. One was packed with blister-wrack and bladder-wrack, bitter seaweeds that Gidney boiled down into poultices for swollen joints; the other held roots of sea-holly, dug from the sand-dunes before the dawn broke cold and pale over the horizon.

"Step lively, boy, or I’ll leave you to swim it," called a rasping voice from the stone watch-house that guarded the island end of the causeway.

Joram sat on a three-legged stool in the lee of the stone wall, a stub of tallow candle flickering inside a horn lantern at his elbow. He was the toll-keeper of Black Isle, a man whose skin resembled salted cod and whose temper was somewhat less agreeable. In his lap rested the leather-bound ledger in which every horse, pig, barrel of brandy, and woolen coat entering the island was meticulously logged for the local magistrate’s tax.

"The tide has another half-hour before the sand-bar disappears, Joram," Luke said, lowering his baskets onto the flat top of a boundary marker. He wiped his cold nose on his sleeve. "And the sea-holly doesn't dig itself."

"The water moves faster when the wind comes out of the east," Joram grunted, hawking a thick glob of phlegm into the shale. He tapped his iron-tipped pike against the flagstones. "And the wind is turning. Look out there. The mainland side is thick with them today. Fair-goers, peddlers, and God knows what else fleeing the taxes in the south."

Luke turned his eyes toward the far shore. A quarter-mile away, where the mud gave way to the gorse-covered hills of the mainland, a cluster of dark figures had gathered at the water’s edge. They had been waiting since noon for the wet stones to emerge from the surf. Now that the causeway was clear, the line began to move forward like a jointed iron beetle creeping across the gray mud.

There were oxen hauling timber, drovers whistling behind herds of scrawny swine, and peddlers with A-frame packs strapped to their spines. Black Isle was not a large landmass—barely nine miles from its rocky western snout to the eastern fishing hamlets—but it held the only deep-water haven for forty miles of wild coast. Goods landed at the Haven were carried along the island’s single thoroughfare, the Spine Road, before being ferried back across to the northern shires. Whoever controlled the Spine Road controlled the trade of three counties.

Luke watched the approaching procession with the passive curiosity of an islander. Life on Black Isle was defined by the tide’s clock; everything arrived in rushes and departed in panics.

"Who is that at the lead?" Luke asked, squinting against the glare of the wet mud. "The heavy wagon with the canvas cover?"

Joram peered out beneath his bushy eyebrows, shielding his eyes with a gnarled hand. "That’ll be Master Peter’s rig. Took a load of smoked salt and salted herring over to the mainland four days back. He’s brought his return cargo."

The heavy wagon rumbled across the stone causeway, its broad wooden wheels churning the sea-mud into a black frothy paste. Two bay horses pulled it, their flanks steaming in the damp air, their nostrils flared wide and pink. The driver sat low on the box, huddled inside a oilskin cloak that glistened with brine spray.

As the wagon neared the stone archway of the watch-house, Luke picked up his baskets, intending to let the heavy rig pass before he walked the two miles back to the apothecary’s shop in the Haven. But as the lead horse drew abreast of the gate, it gave a strange, wet cough—a sound like a wet rag being slapped against a stone wall—and dropped its chin until its iron bit nearly scraped the mud.

"Steady there, brute," the driver growled, though his voice lacked conviction. He pulled on the reins, bringing the team to a halt beside Joram’s wooden toll-desk.

Luke stepped back into the shelter of the stone archway. He was no horse-doctor, but he had lived around farm animals long enough to know the sound of a wind-broken lungs. Yet this was not the dry, raspy wheeze of an old plow-horse. The bay horse shuddered, its flanks quivering under its damp coat, and a rope of yellow, frothy mucus dripped from its left nostril onto the cobblestones.

"You’re late, Peter," Joram spat, not rising from his stool. "The water’s already sloshing over the lower spit. Another ten minutes and you’d have been resting at the bottom of the Firth with the crabs."

The driver did not answer immediately. He slowly peeled back the hood of his oilskin cloak. The man was Peter Vane, a carrier who had driven the Spine Road for twenty years, known throughout the island for his loud laugh, his booming baritone in the taprooms, and his fierce arguments over farthings.

Today, Peter looked as though he had been dragged through a mill-race. His skin, usually the ruddy red of a turnip, was ash-gray around the mouth and strangely flushed across the bridge of his nose. His eyes were small, bloodshot spheres embedded in deep sockets of dark violet flesh.

"The mud was thick on the south turnpike," Peter muttered. His tone was flat, hollowed out, as if every word required a deliberate effort of his lungs. "The horses wouldn't trot."

"They look like they're ready for the knacker's yard," Joram observed, dipping his goose-quill into an ink-horn strapped to his belt. "What have you brought back from the south? Wine? Ironwork?"

"Cloth," Peter said. He cleared his throat, but the sound caught in his chest, turning into a tight, dry hack that made his entire torso shudder beneath his heavy cloak. He pressed a hand against his ribs, wincing. "Bales of wool from the valley mills. And four casks of tallow."

Luke took a step closer to the wagon. A scent drifted from the canvas-covered bed—not the warm, oily smell of raw wool, nor the sharp grease of tallow, but something else underneath it. It was a faint, sickly sweet odor, like apples left too long in a dark cellar, mixed with the sharp sourness of stale sweat.

"Peter," Luke said quietly, stepping up to the iron wheel. "Are you taken with a chill?"

The driver turned his heavy head slowly, as if his neck were made of dry timber. He looked at Luke for a moment without recognition before his pupils slowly brought the young man into focus.

"The fog was heavy in the valley, Luke," Peter whispered. "Cold fog. It settles in the throat. Stays there."

"You ought to have Master Gidney look at you when you reach the town," Luke said, leaning over the side of the wagon bed to glance at the cargo. "He has a syrup of horehound and oxymel that loosens the chest."

"Gidney’s a thief who charges three pennies for a spoonful of boiled honey," Peter grumbled, though there was no heat in his words. He reached into his coat and produced a greasy leather purse, fumbling with the drawstring with fingers that seemed stiff and thick. "Here’s your sixpence, Joram. Let me through. The horses need stabling."

Joram took the coins, spat on them for luck, and tossed them into a brass bowl on his desk. "Move along then. There’s three more carts behind you and the tide won't wait for your nag to catch its breath."

Peter pulled on the reins, shouting a dull "Hup!" to the bays. The horses strained against their collars, their hooves slipping on the wet algae of the gateway, and the heavy wagon lurched forward, heading up the rising gradient of the Spine Road toward the interior of the island.

Luke watched it go. The yellow froth from the bay horse’s nose lay on the cold stone between his boots, slowly dissolving in the drizzle. He bent down, instinctively reaching for his handkerchief, then stopped. He picked up a small drift-wood twig instead and touched the fluid. It was thick, sticky, and held a faint yellow cast, streaked with tiny threads of dark blood.

"Dirty water in the south," Joram remarked, dipping his pen again as the next traveler—a peddler leading a donkey laden with tin pots—approached the desk. "Every autumn it’s the same. They drink from the ditches, get the belly-gripes and the throat-rot, and then bring their misery over my causeway. If I had my way, I’d close the gate from Michaelmas to Easter."

"Has there been fever in the valley?" Luke asked, dropping the twig into the sea-brine where the waves were already beginning to lap against the stone wall.

"There’s always fever somewhere," Joram said carelessly. "If it isn't the bloody flux, it’s the smallpox; if it isn't the smallpox, it’s the swamp-shakes. Men die, Luke. That’s why we have churchyards. Name and business, master!" he shouted at the peddler, who was trembling in his thin coat.

"Giles of Oakhaven," the peddler squeaked. "Pots, pans, and needles for the market at the Haven."

"Two pennies for the donkey, a penny for the pack. Pay up or turn back. The tide’s at your heels."

Luke picked up his two wicker hampers, settling the leather strap across his shoulder. The gray sea was indeed rising fast now. The distant mainland shore was disappearing behind a wall of cold, salt-laden fog that rolled off the deep water like smoke from a wet fire. The stones of the causeway were disappearing one by one, swallowed by the gray waves that hissed as they hit the cold masonry.

He turned his back on the Crossing and set off along the Spine Road.

The road was the pulse of Black Isle. It ran from the Crossing in the south, through the low, marshy belly of the island, past the timber mills and the sheep crags, until it reached the sheltered bay of the Haven on the eastern shore. On either side of the dirt track, grey stone walls separated the roadway from small, miserable fields of barley and oats. The houses here were low-slung, built of fieldstone and roofed with thick sods of peat to keep out the gale-force winds that screamed across the Firth in winter.

As Luke walked, he kept a steady pace, the weight of the sea-holly roots pressing into his back. A quarter-mile ahead, he could see Peter Vane’s covered wagon moving slowly up the incline. The wagon’s iron wheels left two deep, dark ruts in the wet clay of the road.

Every few dozen yards, Luke noticed small patches of dark fluid in the mud where the lead horse had coughed or snorted.

He stopped once, setting his baskets down on a flat boulder, and knelt to examine a puddle by the roadside. A drop of red had merged with the gray rainwater—not horse blood, which was dark and thick, but bright, arterial red, diluted by spit.

"He shouldn't be driving those beasts," Luke muttered to himself. "Nor walking himself, if his chest sounds like that."

A cold wind blew off the marsh, carrying with it the sharp, mineral stink of decaying vegetation and salt water. Luke pulled his wool cloak tighter around his neck. He was not a superstitious man—Master Gidney had hammered the nonsense of omens and witches out of him during his first year of apprenticeship—but the air felt heavy today. It was the sort of damp, dead cold that clung to the wool of a coat and never quite left it, even after hours sitting beside a peat fire.

Behind him, a dull boom echoed across the lowlands. It was the sound of the great oak and iron gate at the watch-house swinging shut, followed by the clatter of the heavy cross-bar falling into place.

Joram had locked the Crossing.

For the next six hours, Black Isle was entirely severed from the earth. Nothing could come in; nothing could go out. The sea owned the world between the shores, and the island was left to its own devices under the darkening gray sky.

Luke hoisted his hampers once more and stepped out into the mud, following the dark ruts of the wagon toward the Haven.

The mist did not climb from the sea so much as it bled from the very earth of the Spine Road, thick and smelling of wet shale. By the time Luke Vance reached the western rise of the Haven, his boots were twice their normal weight with accumulated clay, and the straps of his wicker hampers had chewed red ruts into the flesh of his collarbones.

The Haven was a town built in tiers, like an amphitheater designed for some ancient, forgotten tragedy. At the lowest level, where the black harbor water lapped against rotten oak piles, stood the salt-houses, the cooperages, and the low-ceilinged taverns where foreign sailors drank cheap barley spirit and cursed the local tides. Above them, perched on terraces of damp granite, sat the slate-roofed houses of the merchants, their windows narrow and dark to keep out the salt gales. At the very top, overlooking the whole grey assembly like an old tooth, stood the stone tower of the bailiff’s court and the small, squat church of St. Jude of the Reef.

Luke took the shortcut through Deadman’s Lane, a steep, cobbled passageway where the wind always seemed to whistle through the cracks in the masonry like a dying man’s breath. The high stone walls on either side were green with wet liverwort, and the air here was cold and stagnant, untouched by the breeze from the bay.

He stopped outside a narrow, two-story house with a hanging wooden sign that bore the faded image of an iron pestle and mortar. The paint was peeling, curled by years of sea-spray, but the brass knocker on the door was polished until it shone like a cold sun. This was the shop and home of Master Gidney.

Luke pushed the door open, the small bronze bell above the lintel giving a dry, metallic ting.

Inside, the shop was warm, heated by a small peat fire that smoldered in a brick hearth at the back of the room. The air was a thick, confusing soup of smells: the sharp, vinegary bite of pickling brine, the earthy dust of dried roots, the greasy sweetness of mutton fat being rendered for salves, and the unmistakable, lingering odor of old parchment and damp wool. Rows of dark green and blue glass bottles lined the pine shelves, each labeled in Gidney’s precise, cramped hand with Latin names that Luke had spent the last three years memorizing until his brain felt as dry as the roots he dug.

"You’ve been gone long enough to dig the entire dune, boy," a voice dryly observed from the shadows behind the counter.

Master Gidney was a small, round-shouldered man of sixty years, with a bald head that caught the yellow light of the tallow lamp and a pair of spectacles perched so far down his bulbous nose that he had to tilt his head back to look at Luke. He wore a heavy apron of stained leather over a threadbare wool tunic, his sleeves rolled up to reveal forearms covered in pale hair and dark purple ink stains.

"The tide was slow to clear the lower bar, Master," Luke said, hoisting the heavy hampers onto the counter with a wet grunt. "And I had to search three hollows before I found any sea-holly worth the spade. Most of it was rotted by the late rains."

Gidney grunted, stepping forward to peer into the first basket. His short, stubby fingers, their nails permanently blackened by walnut juice and charcoal, reached in and pulled out a long, pale root. He brought it to his nose, sniffed it once, then snapped it in two with a clean crack.

"Good," the old man murmured, inspecting the white meat inside the root. "Dry enough in the center. Not too stringy. The sea-holly is the only thing that keeps the bailiff’s gout from turning into a gangrene of the toe, and the old wretch is already three weeks behind on his payments. If he dies before he settles his ledger, we’ll be eating cabbage broth until Christmas."

"I met Peter Vane at the Crossing," Luke said, unbuttoning his damp cloak and hanging it on a peg near the hearth. He rubbed his hands together over the glowing peat. "He was returning from the south valley with a load of wool and tallow."

"Peter?" Gidney asked, his fingers still sorting through the sea-holly. "A noisy man. Always wants to trade for his wife’s cough-drops with salt herring instead of coin. Did he bring the iron needles I ordered from the mainland smith?"

"I don't know," Luke replied, his mind returning to the wet, yellow froth on the gateway stones. "But he looked ill, Master. Very ill. His horses were coughing as if their lungs were full of gravel, and Peter himself could barely hold the reins. His face was the color of a wet turnip, save for his nose, which was as red as a cherry, and he had a dark purple ring under his eyes."

Gidney stopped his sorting. He held a piece of bladder-wrack in his hand, his thumb tracing the slippery nodules of the weed. "A winter chill, no doubt. The southern valleys are damp valleys. They have none of our clean salt air to sweep the miasma from the ditches. When the damp gets into a fat man like Peter, it settles in his grease and makes him sluggish."

"It didn't look like a common chill," Luke said, stepping closer to the counter. "The horse was dripping yellow mucus, thick and streaked with bright blood. And when Peter spoke, he sounded... hollowed out. Like a dry bladder being squeezed. He said the fog in the valley was cold and stayed in his throat."

Gidney sighed, a long, whistling sound through his nose, and dropped the seaweed back into the hamper. He reached for a linen rag and wiped his hands, his eyes narrowing as he looked at his apprentice through his spectacles.

"Luke, you have a fine imagination, which is a useful thing when one is trying to convince a fisherman’s wife that a pinch of dried daisy-heads will cure her husband’s wandering eye, but it is a dangerous thing in a true apothecary. The world is full of dirty horses and tired carters. If we stopped to marvel at every running nose that came over the Crossing, we’d have no time to boil the grease for the leather-workers."

"I know what a common horse-rot looks like," Luke insisted, his voice quiet but stubborn. "This was different. The smell of the cart... it wasn't just wet wool and tallow. It was sweet. Like cider apples left to rot in a dark corner. It made my tongue feel greasy just to smell it."

Gidney paused, his hand hovering over his ink-horn. The old man’s brow furrowed, a network of deep, yellowed wrinkles appearing above his spectacles. "Sweet?" he asked, his voice losing some of its sharp, mocking edge. "Like dry rot?"

"Yes."

The apothecary stood silent for a moment, the only sound in the shop being the crackle of the peat fire and the distant, rhythmic roar of the tide against the harbor wall. Then, he shook his head, the movement brisk and dismissive, as if shaking off a troublesome fly.

"An old barrel of grease, likely," Gidney said, turning back to his ledgers. "Or some southern fruit he tried to smuggle across to avoid the bailiff’s tax. Go wash your hands, boy. The grease on your fingers is transferring to my sea-holly. Then take the small copper pot and render down the mutton fat with the wild thyme we gathered on Tuesday. Master Vane’s lungs are his own business, but the bailiff’s gout is ours."

Luke knew better than to argue when the old man’s voice took on that flat, decisive tone. He nodded, took his leather apron from its peg, and walked into the small back room where the copper vessels and the water butts were kept.

Yet, as he dipped his wooden ladle into the fat-pot, his mind remained on the road. He could still hear the dry, rattling hack of Peter Vane’s chest. It had not sounded like the loose, wet cough of a man who had taken a splash of cold river water; it had sounded like something dry and hard was trying to claw its way out of the carter’s throat.

By nightfall, the fog had crawled up from the harbor and swallowed the Haven entire.

The yellow oil lamps of the taverns down on the quay were nothing but faint, greasy smudges in the darkness, and the silence that settled over the town was heavy, broken only by the occasional bark of a dog or the rattle of a loose slate in the wind.

Luke sat in the small loft above the shop, his knees drawn up to his chin under a thin woolen blanket. The loft was cold, the wind whistling through the cracks in the roof tiles, but he had a small view of the street below through a tiny, triangular window in the gable.

The Spine Road was quiet. Under the dark sky, the mud of the road looked like a river of black ink.

At midnight, he heard the sound of footsteps on the cobbles below—heavy, uneven steps that dragged and slipped on the wet stones. He leaned closer to the glass, his breath fogging the small pane, and wiped it clean with his sleeve.

A figure was walking up the hill from the direction of the lower town. It was not Peter Vane, but one of the harbor porters—a broad, thick-shouldered man named Barnaby, who made his living carrying sacks of salt from the ships to the curing houses. He was a man who could carry two hundredweight of iron on his back without a murmur.

But tonight, Barnaby was not carrying anything. He walked with his arms hanging limp at his sides, his head tilted back as if he were trying to find air in the thick fog. Every few steps, he would stop, lean his forehead against the rough stone of a house wall, and stand there trembling for a minute before dragging himself forward again.

Even from the height of the loft, Luke could hear the sound of the man's breathing.

It was a wet, rattling gasp, like water bubbling through a narrow pipe. Barnaby did not cough; he simply whistled with every breath, his chest heaving under his canvas jerkin.

As Luke watched, the porter reached the corner of Deadman’s Lane and stumbled. He did not fall clean, but slid down the wet stone wall until he was sitting in the mud of the gutter, his legs splayed out before him. He sat there for a long time, his face turned upward toward the gray sky, his mouth open wide like a fish landed on a gravel bank.

Luke reached for his boots, his fingers cold as he fumbled with the laces. He didn't know what he intended to do—perhaps only to offer the man a hand, or to bring him a cup of the small-beer Gidney kept in the cellar—but before he could tie the second knot, a door creaked open across the lane.

It was Maura, the widow who lived opposite the shop, a woman who earned her bread by washing linen for the ships’ captains. She came out with a wooden bucket of dirty suds, intending to empty it into the common gutter before the frost took the street.

She stopped when she saw the shape in the mud.

"Barnaby?" she called out, her voice thin and sharp in the cold air. "Is that you, you great lump? Have you been at the black beer again?"

The porter did not answer. He made a low, bubbling sound in his throat and turned his head toward her. In the faint, gray light of the rising moon behind the fog, his face appeared strangely white, save for his lips, which were dark, almost black, like the skin of a bruised plum.

Maura took a step closer, then stopped. She did not empty her bucket. Instead, she let it drop, the gray water splashing over her clogs and running down the hill in a greasy stream.

"Mother of God," she whispered.

She did not touch him. She turned and ran back into her house, the heavy oak door slamming shut with a sound that echoed through the empty street like a gunshot.

Luke sat on the edge of his pallet, his bootlaces half-tied, his heart drumming a wild, uneven rhythm against his ribs. He looked back out the window.

Barnaby had managed to get to his feet again. He did not look back at Maura’s door. He simply continued his slow, dragging march up the hill, his head tilted back, his hands scraping along the rough stone walls as he went, leaving a faint, dark smudge on the gray granite wherever his fingers touched.

He was heading toward the Spine Road, toward the houses of the upper town, where the air was supposed to be clean.

Luke slowly untied his boots and lay back down on the straw, but he did not sleep.

The wind had shifted. It was coming from the south now, blowing soft and warm over the low salt marshes, carrying with it the smell of the damp valleys beyond the Crossing. It was a wet, heavy air that felt too thick to breathe, as if the sea itself were turning into vapor and settling over the island like a gray shroud.

In the dark, he listened to the small noises of the old house—the creak of the timber rafters, the scurry of mice in the thatch, and, from the room below, the low, steady snoring of Master Gidney.

But beneath those familiar sounds, Luke fancied he could hear something else. A faint, collective sigh rising from the lower terraces of the town, a soft, dry whistling of a hundred lungs trying to find a breath of air in the dark, while the tide outside the harbor walls turned and began its long, cold creep back toward the stone gate of the Crossing.
