The fog came first, thicker than wool and tasting of brine and burnt sugar. Nella Vross pulled her hood lower as the ferry slid between the rusted pilings of the outer gate, and Murkmere opened before her the way a wound opens under a surgeon's blade: slow, wet, and impossible to look away from.
She had counted the lanterns from the Cindermarch crossing. Forty-three to the first bridge. Forty-three more to the customs dock. The numbers had kept her hands from shaking, which was the only reason she counted them.
The deck beneath her boots was slick with something she chose not to examine. Somewhere below, the engine coughed in a rhythm she recognized from her years riding the surgeon's cart through the lower wards of her own city, that arrhythmic heartbeat of a machine being asked to do more than it was built for. Smoke-wardens rode engines built to drown. This one was built to carry rich men to pleasure gardens, and it complained about every passenger it wasn't paid to want.
A child darted past her, bare feet slapping the wet planks. Nella's hand moved to the small of her back before her mind caught up, fingers brushing the hilt of the belt knife she'd taken off a man who'd tried to take more off her. The child didn't look back. Children on ferries learned early that looking back was a luxury.
"Murkmere!" the ferryman called, his voice carrying the particular grandeur of men paid by the shout. "Last stop for the honest and the curious! All others, mind your step."
Nella stepped off the gangplank onto stone that had been walked on for nine hundred years and had the wear to prove it. Her boots sank slightly into a slick of moss and lamp soot. Above her, the city climbed in a chaos of balconies, rope bridges, and wooden spires that had no business standing, yet did, the way all impossible things in Murkmere did, through stubbornness and a little help from bribes.
She did not look up at the banners of the Ashfall Guild snapping from the customs tower. She had seen enough of that sigil, the smoking lantern wreathed in cinder-flame, stitched onto the shoulders of men who had come to collect her from the ruins of her mentor's clinic. Men who had stood in the smoke and done nothing while the roof came down. She had opinions about that sigil, and none of them were suitable for embroidery.
The customs dock was a cathedral of bad decisions. Stalls slumped against the quay wall, selling fried river-eel, roasted gourd, and small clay pots of something the locals called black tea but which smelled, to Nella's trained nose, of boiled boot leather and medicinal bark. A one-armed woman hawked tooth-pulls from a folding chair. Two boys fought over a crate of glass eyeballs, the sort used by procurers to identify marks in the gambling houses.
Nella pushed through the crowd, keeping her shoulders tight. She had learned the trick of moving through a press of bodies without touching more than necessary; it was a skill taught to her by a man now dead, and she did not think of him by name, because names were how the bounty hunters found you. They followed names the way her old guildmaster had taught her to follow the curl of smoke: by shape, by weight, by the places it bent toward.
She needed to find Pock.
Pock was not a name that appeared on any guild roster. Pock was not a name that appeared anywhere except in the mouths of people who needed something moved, hidden, or carried quietly across rooftops at unreasonable hours. He was, by all accounts, twelve years old, though Nella suspected the accounts had been written by the same sorts of men who wrote down the height of the city's walls and were off by a quarter in either direction.
She found him exactly where the harbor-rumors said he would be: perched on an overturned anchor at the edge of the customs dock, swinging his legs, eating something fried from a paper cone. He wore a coat three sizes too large for him, the sleeves rolled into mittens, and a grin that suggested he had already taken inventory of her purse and her boots and was deciding which one to admire more.
"You Vross?" he said, before she could open her mouth. His voice was high and slightly nasal, the vowels drawn long the way dock-rats draw them when they want you to know they've been places. "The woman from the Cindermarch? With the guild mark burned off her shoulder and the bounty on her head that could feed a family for a season?"
"I haven't burned anything off my shoulder."
"Smoke-wardens say you have. Bounty notice has a sketch. It looks a bit like you, if you squint and the wind is right." He bit into whatever was in the cone. It crunched. "Also, your boots are wrong for Murkmere. Guild folk wear boots with a heel. Yours are flat. Surgeon's boots."
"You're observant for a child."
"I'm observant for anyone. And I'm not a child. I'm twelve." He held up the hand not holding the cone, fingers spread, as if this proved something. "Pock. You're looking for me. Don't lie and say you aren't, because I've been told you don't lie, which is stupid, because everyone lies, but it's useful information for me, so."
Nella studied him. He had the look of canal children, all elbows and soot, the sort who learned to read ledgers before they learned to read poetry. His eyes, though, were sharper than the rest of him. They flicked to her collar, her sleeves, the scab on her knuckles, and back to her face in the time it took her to draw a breath.
"Where did you hear I don't lie?"
"I hear lots of things. I hear that you were a surgeon's apprentice under a man named Havel, that the Red Riot burned his clinic to the waterline, that you stitched up half the docklands with your own belt for a tourniquet, and that you left your city watch badge on the desk of the chief warden with a one-word note that I won't repeat because it had the word 'cowards' in it, which is a brave word for a woman with a price on her head the size of a guild pension." He paused, chewing. "I also hear you pay in coin, not promises."
"Havel's clinic." The words came out before she could stop them. They sat in her mouth like copper. "What else do you hear about that night?"
"That the smoke-wardens of your fair Cindermarch stood in a ring around the building and let it burn. That the guildmaster took a brief meeting in his office while the roof came down. That Havel's body was never recovered, because there wasn't enough of one to recover." Pock said this with the same cheerful rhythm he'd used for the boots. Children who grew up around death learned to rhyme with it. "I hear you walked out of the smoke with a bloodstained apron and a look that has made grown men step off the sidewalk. I hear you're here because the bounty hunters have run out of places to look in your own city and have started asking around the canals."
Nella's hand found the small of her back again. Not the knife this time. The scar, the one that ran from her left shoulder blade to her hip. The shape of the falling beam. The shape she traced when she couldn't sleep, which was most nights.
"What I need," she said, "is a place to sleep that isn't a bounty hunter's idea. A week. Maybe two."
"A week of not being found. In Murkmere. During the Cindermarch fair." Pock whistled, low and impressed. "That's a tall order. The fair brings every cutpurse, river-pirate, and guild-marked hunter between here and the southern locks. You understand what you're asking?"
"I understand exactly what I'm asking. Can you do it?"
Pock hopped off the anchor. He was shorter than she'd expected. He had to tilt his head back to look up at her, and he did it with the air of a man inspecting a horse he might buy.
"Can I do it," he repeated. "Lady, I can hide you in a crate of pickled eels. I can hide you under a fishmonger's apron. I can hide you in plain sight on a barge full of pilgrims going upriver to the singing bridges, where every face is a stranger and nobody looks twice at a woman with a soot-streak on her cheek. The question is not can I do it. The question is what are you willing to pay, and what are you willing to carry."
"Carry?"
"News travels. I am the news. I move it. If you want to disappear, you need me to move the wrong news about where you are. I need to tell people you went north, or south, or into the marsh-tombs under the old canal, and I need to tell them with enough conviction that when the hunters come sniffing, they sniff the wrong way." He stuck out his hand. It was small and dirty and very serious. "I don't work for coin only. I work for stories."
"Stories."
"You heard me. I'm twelve. I like stories. I'm partial to the ones where the hero gets one over on the men who think they own the city. I'm partial to stories with a moral, and a bit of blood, and a woman at the center of them who isn't just waiting to be rescued by some lantern-jawed boy with a guild sword." He grinned again, gap-toothed. "You've got a story, Vross. I want a chapter of it. A good one. With names."
Nella looked at his hand. She thought of Havel, who had taken her on as an apprentice because she'd fished a glass shard out of a stable boy's thigh with a pair of kitchen tongs and steady hands. She thought of the way he'd laughed when she'd told him she wanted to be a surgeon, not a healer, because surgeons got to keep their tools. She thought of the smoke, the smoke, the way it had come through the window of the clinic in a wall of black, and the way the building had groaned, not like a dying beast but like a ship giving up its mast.
She took Pock's hand. His grip was stronger than it looked.
"One chapter," she said. "When I'm out of Murkmere."
"Done. Now, the pickled eels are a joke. You'd suffocate." He reached into the too-large coat and produced a folded square of paper, which he shook open like a fan. It was a map of the canal-city, hand-drawn in red ink, the lines of the major waterways marked in blue. He pointed with a finger that had been bitten down to the quick. "Your hunters will work the customs gate first. They always do. Then they'll work the inns on the Cutthroat, which is where the Cindermarch guild stays when they're in town, because they like their beds soft and their wine in glass. Then they'll start working the clinics, because they know you've got the healer's instinct, and healers go to healers when they're hurt."
"You've thought about this."
"I've thought about everything. I'm twelve. Thinking is my job." He traced a route along the map, his nail leaving a faint red line on the paper. "What I need to do is get you off the main canals and into the part of the city the guild doesn't like to walk through. The Salt Ladder. It's where the river meets the marsh, where the buildings lean like they're tired, and the watch doesn't patrol after dark because the watch is paid not to patrol after dark."
"You're talking about bribed watchmen."
"I'm talking about practical arrangements between the watch and the people who actually live here. Don't moralize at me, Vross. I'm twelve. I don't have time." He folded the map with a practiced snap. "There's a woman in the Salt Ladder. Old Maerlyn. She keeps an herb shop at the top of the worst stair in the city. She owes me a favor, which is a sentence I never thought I'd say, because she doesn't like owing anyone anything, but I once carried a packet of her dried root across the rooftops in a rain that would have drowned a duck, and she said if I ever needed a thing she could give, she'd give it. This is the thing."
"What sort of favor?"
"The sort that involves a spare room, a kettle, and a woman who doesn't ask questions because she already knows the answers." Pock started walking. Nella fell into step beside him, and the crowd parted around them the way crowds part around a boy with a too-large coat and a woman with the look of someone who has stopped caring what she looks like. "Also, Maerlyn's got a way with smoke. She can tell a person by the way their clothes smell of it. She'll know you're guild-trained, and she'll know you left under bad terms, and she'll know you stitched up half the docklands with your own belt, because the news of that got down the river faster than the guild's apology, which is to say, it got here, and the apology didn't."
Nella followed him up a set of stone steps that had been worn into bowls by nine centuries of feet. The fog thinned as they climbed, but the air grew heavier, wet with the breath of the marsh. Below them, the city spread out in a maze of bridges and barges, lanterns winking on in the deepening dusk like the eyes of animals deciding whether to trust the dark.
"Why are you doing this?" she asked. "Truly. Not the stories. Not the coin. Why?"
Pock didn't turn around. He kept walking, his coat flapping behind him like the wings of a small, scruffy angel that had decided to specialize in courier work.
"Because three years ago," he said, "my sister got a cough that wouldn't stop. I carried her to six healers. Six. The first five took coin and told us to pray. The sixth was a smoke-warden from your city, down on the river for the fair, and he looked at her and said the guild mark on her chest said he had to send word to the Cindermarch first, and by the time the word got there and the permission came back, my sister was a small, cold thing I had to bury under the docks." His voice didn't change. The words came out in the same cheerful, nasal rhythm. "I am not sentimental about smoke-wardens. But I am sentimental about women who learn to stitch with kitchen tongs. So when I heard you'd left your badge on the chief warden's desk and a one-word note on top of it, I thought: that is a person who might be worth the trouble of hiding. Even from the guild. Especially from the guild."
They walked in silence for a while. The sounds of the city rose around them: the slap of oars, the complaint of pulleys, the distant singing of a barge-poler with a voice like a wet saw. Somewhere above, a bell rang the hour, low and slow, the way bells ring in cities built on water and secrets.
"Maerlyn will want something," Nella said.
"Maerlyn always wants something. She wants a story too, but a different kind. She wants to know why you left, and she wants to hear it in your own words, and she wants you to be honest, which is a thing she is very good at detecting and very quick to punish." Pock glanced back at her, and for a moment the grin was gone and there was just the child underneath, sharp-eyed and tired. "Be honest with her, Vross. She is the closest thing to honest I have ever met, and I have met a lot of things."
The stairs narrowed. The lanterns dimmed. Ahead of them, at the top of the worst stair in Murkmere, a door stood open to the marsh wind, and a thin line of smoke, blue and bitter, curled out into the night like a question waiting to be answered.
The blue smoke curled around Nella's boots like a cat looking for a warm lap. She stepped over the threshold, and the smell hit her first: dried rosemary, something older and darker underneath, and beneath that the wet-rot sweetness of marsh water seeping through floorboards. Old Maerlyn's rooms had always smelled like the bottom of a peat bog left out in the sun.
"Pock." The word came out more breath than voice. "Wait."
He paused, half in, half out. The street behind him was a black mouth. He didn't turn, but she saw his shoulders tighten, the way a boy's shoulders tighten when he knows what's coming and is already bracing for the blow.
"I should tell you," she said. "So you can decide."
"Mm." He tilted his head. The smoke-warden mark on his ear caught the lamplight and made it look like a coin pressed into skin. "Decide what?"
"Whether you want to be on the dock when the ash-folk come looking."
He was quiet for a long moment. Then, very softly: "I have decided."
"You haven't heard what I, "
"Vross." He turned then, and his face was the face of a boy who had decided many things before his tenth birthday and none of them had been soft. "I have been on the dock for a year. I will be on the dock tomorrow. If you want to scare me, you will need a different story."
She almost laughed. Almost.
Maerlyn's sitting room was smaller than Nella remembered. The walls had been hung with bundles of dried herbs and small bone fetishes on leather thongs, and the fireplace was no more than a circle of soot-blackened stones with a kettle balanced on a tripod. A single candle burned on a low table, the flame leaning hard to one side as if listening. The herb-witch sat cross-legged on a faded rug, her hair the color of tarnished silver, her face a sketch of itself, all angles and shadows. She looked up when they came in. Her eyes were the pale blue of a winter sky and just as warm.
"Nella Vross." The voice was thin, dry, a wind through dead reeds. "You are thinner than the girl I knew. And you walk like a woman expecting the floor to give."
"Mistress."
"Sit. Both of you. The rug is older than either of you and has borne worse."
Pock sat. Nella did not. She stood with her back to the door and her hands loose at her sides, and she watched the old woman's fingers, which were long and stained and did not quite still. A ring on the second finger of the left hand caught the candlelight: black iron, no stone, etched with a pattern that was not quite a pattern. Nella had seen that ring before. She had seen it on a different finger, in a different room, on the night the Red Riot came down Wren Street and her mentor's clinic went up in smoke that tasted of sulfur and burning hair.
"You have questions," Maerlyn said.
"I have one."
"The guild. Yes. I suspected." The old woman picked up a clay pipe from beside the candle, a small dark thing with a long stem, and began to fill it from a leather pouch. Her movements were precise, almost ritual. "They do not send the quiet ones. The quiet ones are the ones who keep lists. They have come for a reason, and the reason will be specific, and the reason will have your name folded into it like a letter inside a letter. Sit down, child. Your standing makes my neck hurt, and I am too old to be made to look up at people who are not even paying me the courtesy of being taller than me."
Nella sat. The rug smelled of dogs and woodsmoke and something faintly metallic, like old blood.
"A year," Maerlyn said, tamping the tobacco with a small bronze tool. "A year you have been a ghost in my city. You stitched beggars in the wharfside alleys. You brewed fever-tea for the canal children. You let Pock run your errands and did not ask him where he got the coin, which was kind, and which was also foolish. And in all that time you did not come up the stair. You did not knock on the door. You let the city think you were no one."
"I was no one."
"You were no one the way a knife is no one when it is sheathed. That is not the same thing, and you know it." She lit the pipe with a twig from the fire, sucked until the bowl glowed, and then exhaled a thin stream of smoke toward the ceiling. "What changed?"
Nella was quiet for a moment. Pock, cross-legged at the edge of the rug, was watching her with the bright stillness of a boy watching a rigged card game. She did not want to say it. She did not want to give it weight in this room, in this voice, in front of this old woman who already knew too much and pitied too easily and would, if asked, take the burden on herself and bear it until it broke her, which was a thing Nella had decided a year ago she would not allow.
But she had come to ask. And you do not ask an herb-witch for favors without paying the price of an honest answer. That was the first rule. The second rule was that the price was always higher than you expected.
"A man," she said. "Tonight. On the Mardle steps."
"The Mardle steps are where the river-folk go to die."
"He didn't die on the steps. He died coming up them. I found him in the boarding house in Tallow Lane, the one with the green shutter. The landlady said he came in at sundown and asked for a room with a view of the bridge and paid in copper and did not come down for his supper."
Maerlyn's pipe-smoke thickened. "You went in."
"I went in." Nella reached into the pocket of her coat and drew out, very carefully, by the very edges, a thing wrapped in a scrap of linen. She set it on the table between them. The candle flame leaned toward it as if curious. "He was on the floor. The rats had been at him. But his hands were crossed on his chest, like a man waiting to be buried, and in his right hand he held this."
She unfolded the linen.
The lens-glass lay on the pale cloth like a sleeping eye. It was perhaps three inches across, the rim of it cracked across one quadrant and the glass itself fogged with a residue that was not quite dust and not quite ash and that caught the candlelight in a way that made the light look sick. Even through the linen Nella had felt it: a faint vibration, a hum just below the threshold of hearing, like a wasp trapped in a jar.
Maerlyn did not touch it. She leaned forward, and the pipe-smoke from her exhale curled around the lens-glass and was pulled, slowly, into the fog on its surface. The old woman's face changed. The lines around her mouth deepened. The pale blue of her eyes went flat and hard.
"Where," she said, very softly, "did you say he came from?"
"I didn't. I don't know. He had no papers. No letters. No tokens. But he had this, and he had, " Nella stopped. Reached into her coat again. Drew out a second scrap of linen, smaller, and unfolded it on the table beside the lens-glass.
On the linen, in black, the size of a thumbnail, was the mark of the Ashfall Guild.
It was not a brand exactly. It was more like a stain that had been pressed into the skin while the skin was still warm, so that the flesh had accepted it as a wound and healed around it. A spiral of black smoke, dense at the center and thinning as it curled outward, until at the edge it was only a suggestion, only a rumor of smoke. It did not move. It never moved. Nella had seen it three times in her life, and each time it had been on the wrist of a man who was already dead or close to it.
Maerlyn set down her pipe.
"Show me your wrist."
"Mistress, "
"Show me your wrist, Nella."
Nella pushed back the cuff of her coat. The skin of her inner wrist was bare, unmarked, the veins showing blue through the pale. The old woman looked at it for a long moment. Then she reached out, very slowly, and laid two fingers against the pulse point. The fingers were cold. The touch was light.
"The hum," Maerlyn murmured, almost to herself. "You feel it. You have felt it for a year, and you thought it was the river, and you thought it was the city's breathing, and you thought it was your own grief. But it is not."
"I don't, "
"Hush." The fingers tightened, just slightly. "Listen."
Nella listened.
And she heard it. Not with her ears. With something lower, something in the bone behind her ears, something that had been there a year and a night, since the night the clinic had burned and her mentor had not come out and the smoke had tasted of sulfur and burning hair. A hum. A single note, held forever, just below the threshold of hearing.
The lens-glass on the table brightened.
The fog on its surface moved.
"Oh," said Pock, in a very small voice.
The smoke of the spiral, the black mark on the linen, began to uncurl. It rose from the cloth like a slow, deliberate snake, thickening as it rose, until it stood an inch above the linen, and then two, and then it had a shape that was not quite a shape, a suggestion of shoulders and a suggestion of a face and a suggestion of eyes that were not eyes but only the memory of eyes. The candle flame bent sideways as if pressed by an invisible thumb. The air in the room went cold.
Maerlyn did not move. Her hand on Nella's wrist did not move. Her face did not move. Only her mouth, which shaped, without sound, a word that Nella did not know.
The smoke-shape leaned forward. It had no smell, but Nella smelled it: wet ash, old copper, and beneath that, faint and unmistakable, the lavender-and-rosemary scent of the back room of a clinic in Wren Street, where her mentor had kept the bone saws and the cauterizing irons and the small leather book in which she had written the names of the dead.
The smoke-shape spoke. The voice was not a voice. It was a hum with words folded into it, a single note on which a sentence had been pressed like a flower into a book.
"Nella Vross. Apprentice of Maren Dulse, surgeon, unregistered. Last seen Wren Street, year of the Red Riot. Believed lost. Believed compliant. Believed silenced."
The hum deepened.
"You are none of these things. And we have come to collect what is owed."
The smoke-shape leaned closer. The cold in the room thickened until Nella could see her own breath. Pock had pressed himself back against the wall, his eyes very wide, his hand at his belt where he kept his little knife. Maerlyn's grip on Nella's wrist was iron.
"It cannot hurt you here," the old woman said, and her voice was steady, and her voice was thin, and her voice did not waver. "It is only a sending. A long thread. The hand at the other end of the thread is far away, and it cannot reach through me, not in this room, not while the herbs are burning, not while the bones are listening. But the thread is real, child. And the hand at the other end knows now exactly where you are."
The smoke-shape inclined what might have been its head.
"Ashfall does not forget. Ashfall does not forgive. You were given a debt. The debt is come due."
It did not bow. It did not curtsy. It simply came apart, the way smoke comes apart in a still room, thinning and thinning until there was nothing left but a faint smell and a black residue on the linen that looked, if you looked at it from the corner of your eye, like the shape of a closed eye.
The lens-glass on the table went dark. The hum in Nella's bones went silent. The candle flame, released, straightened itself and burned on as if nothing had happened.
The room was very quiet.
Pock let out a breath that was almost a sob. "I am going to need to be paid more for this."
Maerlyn did not smile. She released Nella's wrist and sat back, and the motion cost her, Nella saw, cost her something she would not show. The old woman's hands, when they settled in her lap, were trembling.
"A debt," Nella said. Her voice was her own. That surprised her. "What debt?"
"Your mentor." Maerlyn's voice was a thread. "Maren Dulse. In the year before the Red Riot, in the winter when the fever was on the city and the dead were stacked like firewood in the chapel yards, she took a patient. A man with a wound that would not heal. She did what she could. She was a surgeon, not a witch, but she had the sight, and the sight told her that the wound was not a wound. It was a door. And the door had been made by the Ashfall Guild, and behind the door was something that wanted out."
"What did she do?"
"She closed the door. She had to. The man was dying. The thing behind the door would have taken him and then the room and then the street. She closed the door, and in closing it she took a piece of the guild's work into herself. A splinter of the spell. A fragment of the debt."
"And they want it back."
"They want it back. They have wanted it back for fourteen years. They do not forgive. They do not forget." Maerlyn looked at Nella, and for the first time since Nella had known her, the pale blue eyes were not hard. They were tired. "And when Maren died, the splinter passed. To her apprentice. To the one who held her hand at the end. To you."
The candle guttered. The herbs on the walls rustled though there was no wind.
"You have been a ghost," the old woman said. "But ghosts do not hum. You have been a beacon. You have been walking the streets of my city with a splinter of the guild's own work in your marrow, and every step you took, you sang to them. And tonight, when you took that lens-glass from the dead man's hand, you answered."
Nella looked down at her own wrist. The skin was bare. The veins were blue. The hum was gone.
For now.
"I didn't know," she said. "Maerlyn, I didn't know."
"No. You did not know. That is the cruelty of it. That is always the cruelty of it." The old woman reached for her pipe, and her hand shook, and she set it down again. "They cannot take the splinter by force. It is in you. To take it they would have to unmake you, and unmake you would be to break the door wide open, and the door must not open. So they have sent the quiet ones. They have sent the ones who keep lists. And they will come for you, Nella. Not tonight. Not tomorrow. But soon. And they will offer you a trade. They will offer you your life, your freedom, your name. And the price of the trade will be the splinter, and the splinter is the door, and the door is the thing they made, and the thing they made must not be let out."
The fire popped. Pock's breathing had steadied, but his hand was still at his belt.
"What do I do?"
Maerlyn was quiet for a long time. The candle burned. The smoke from the pipe, which had gone out, curled in a thin line toward the ceiling and dispersed.
"You do what Maren would have done. You do what I could not do, and Tess could not do, and the long line of women who keep the small books and the small lamps could not do. You run. And you do not stop running. You find the places the guild does not look. You keep the splinter quiet. You learn to sing a different song." The old woman's voice dropped to a whisper. "Or you find the man who holds the other end of the thread, and you cut the thread, and you cut it clean, and you pay the price of the cut in whatever coin the cutting takes."
"What coin?"
Maerlyn looked at her. In the candlelight her face was a sketch of itself, all angles and shadows, and at the corners of her mouth there was the ghost of a smile that was not a smile.
"That," she said, "is the part of the story I do not yet know."
She reached into the folds of her dress and drew out a small leather pouch, no bigger than a walnut, and from the pouch she took a single coin. It was not copper. It was not silver. It was black iron, the same black iron as her ring, and on one face of it was a symbol Nella did not recognize, and on the other face was nothing at all.
"Take it," Maerlyn said. "It will not save you. But it will buy you the time of one true answer from one true person. And one true answer, in this city, in this year, is worth more than a house."
Nella took the coin. It was cold. It was heavier than it looked. It did not hum.
Pock cleared his throat. "I am going to need more copper," he said, "to forget that I saw what I just saw."
"You will forget nothing," Maerlyn said, "and I will pay you nothing, and you will be at the foot of the stair at dawn, because you are a boy who keeps his word, and there are not many of those left."
The old woman stood. It cost her. Nella saw it cost her. She crossed to the door, and she opened it, and the marsh wind came in and the smell of it was wet and green and did not smell, for once, of ash.
"Go," Maerlyn said. "Both of you. Go down the stair. Go to the places the guild does not look. And when the quiet ones come, and they will come, you will know what to do. You have known it for a year. You have been doing it for a year. You just did not know that you knew."
Nella stood at the door. Behind her, Pock was already on the stair, his feet quick and sure. Before her, the city of Murkmere lay spread out under a low sky, the lanterns of the bridges bobbing on the black water, the bells of the chapel of the river-saints ringing the small hours in their slow, patient way.
She put the black-iron coin in her pocket, beside the lens-glass and the linen with the smoke-mark. The coin was cold. The lens-glass was silent. The linen was only linen.
But the hum in her bones was there, just under the skin, waiting.
She went down the stair. Pock was three steps below her, and he did not look back, and she did not need him to. At the bottom, the alley smelled of fish and rain, and somewhere a dog barked once and then was quiet.
