The dream began where all of Silas Cobb's worst nights began: in his own garage, with the lights already on.
He stood among engines that breathed. His boots planted on concrete that had the texture of warm bread. The familiar bays stretched away into a fog that smelled of cut lavender and old pennies, and at his left elbow stood Wren Alderton, though he had not heard her come in. Crouched beside Wren was a child who could not have been older than nine, dressed in a coat sewn from what appeared to be cured balloon-canvas. Her hair was the color of an unwashed engine block. She was smiling up at him with too many teeth.
"Mr. Cobb," the child said, in a voice as soft as a kettle just before it whistles. "I've been meaning to talk to you about your clutch."
He opened his mouth to answer. The garage rearranged itself around his tongue.
The hydraulic lift folded into a small stage. The tool wall walked itself sideways, the wrenches chattering on their hooks like sparrows disturbed from a hedge. From the back of the workshop a curtain rippled as if a wind had blown through walls that had no windows, and three shapes stepped out of the dark behind it.
"Moth," Wren said. Her voice carried the particular caution Silas had come to recognise from years of watching her work on customer vehicles: the kind that said, I am about to do something foolish, and I would like credit for it later. "Where are we, exactly?"
"Dreaming," the child said, as though this were obvious. "Mr. Cobb's dreaming, mostly. You're borrowing. Come along."
She took Wren's hand with the easy authority of a guide who has given the same tour a thousand times. Silas tried to follow. His boots stuck to the floor as if it had become tar, and he watched them walk on without him.
The first shape resolved itself at the foot of a ramp. A scooter, small and eggshell-blue, with a windscreen scratched into a permanent squint and a paint job that someone had clearly loved and then loved harder. A Vespa. She idled with the particular haughtiness of a thing that knew its own worth and refused to pretend otherwise.
"Pearl," Moth announced. "She was the Talbot-Lago's first keeper. Before the war."
The Vespa's headlamp flicked on, then off, then on again. A slow blink. When she spoke, her vowels had the crisp, clipped edges of a headmistress addressing a pupil who had tracked mud across her parquet.
"I was not," the Vespa said, "introduced. I introduced myself. The distinction matters."
"Hello, Pearl," Wren said.
"You may call me Pearl." The Vespa's engine ticked once, sharply. "You may not pat my tank. You may not ask after my mileage. You may not, under any circumstances, suggest that I am tired. I have never been tired. Tiredness is for machines that have not been maintained."
Wren's mouth twitched at one corner. "Noted."
Pearl's mirror turned, slowly, toward Silas. The headlamp dimmed to a knowing glow. She studied him the way a jeweller studies a stone that has been submitted for valuation, and found him, he understood at once, somewhat wanting.
"And you," she said, "are the one who keeps this garage. I have heard of you."
Silas tried to speak. His tongue had gone numb with the particular numbness of a dreamer who knows he is dreaming and cannot find the off-switch.
Pearl made a sound that might, in another vehicle, have been a sigh. Her mirror folded back against her body with a small offended click. "Yes," she said. "Quite."
Moth tugged Wren onward. The Vespa watched them go with the resigned patience of a dowager at a garden party watching children chase each other across the lawn.
The second curtain parted of its own accord. Bertha waited behind it.
She had been a school bus once. She had been a school bus in the way that some women had been governesses: formally, with a great deal of authority, and with a particular fondness for telling other people where to sit. Her paintwork was the institutional yellow of a thousand forgotten class photographs, faded now to the color of weak tea with a little milk in it. Her tyres were enormous. Her bonnet bore a small painted name in careful cursive, BERTHA, in letters the size of a child's hand.
She did not idle. She purred. The sound filled the dream-garage the way the smell of a bakery fills a side street at five in the morning.
"Oh," Bertha said, in a voice as warm as a tea towel just folded from the airing cupboard. "Oh, oh, oh. Look at you. Look at your face. Sit down, sit down, you must be tired, you must be hungry, I have digestive biscuits somewhere."
"Pearl says no one here is tired," Wren murmured.
"Pearl," Bertha replied, with the air of a woman long practised at saying the name, "is a Vespa. Vespae do not get tired. Vespae get opinions." The bus's headlights blinked once, twice, in what was unmistakably amusement. "Now then. Who is this with you?"
Her radiator grille swung toward Silas. A small vanity mirror extended from her wing on a slender stalk, angled to study him with the frank curiosity of an aunt at a christening who has already begun composing her comments on the canapes.
"This is Mr. Cobb," Moth said. "He owns the garage."
"Does he now." Bertha's engine revved gently, the way a fond grandmother might clear her throat before delivering a compliment. "Handsome man. Strong forearms. You look underfed. I will not hear a word against my digestive biscuits."
"I haven't eaten any of your biscuits," Silas said, and was surprised to find his voice had returned. It came out in a Yorkshire rasp, but quieter than usual, as though the dream had laid a thumb across his usual bluster.
"You haven't yet," Bertha said. Her mirror folded itself back with a small decisive snap. "But you will. I know the look. I have seen it on four hundred and sixty-two schoolteachers and not one of them was wrong."
She rumbled again, low and contented, and Silas understood with the peculiar certainty of dreams that somewhere beyond the fog of this garage, in the real workshop, he had actually left a packet of biscuits on the bench by the kettle and forgotten about them. He had the uneasy feeling he had been meant to.
"Moth," Wren said, "where are you taking me?"
"To the back," Moth said. "To the one who minds."
The third curtain was heavier than the others. Moth had to put her shoulder into it. Behind it the air changed at once. It tasted of diesel fuel and ozone. It tasted of a long road at the end of which someone had broken down and not been helped.
Rows of vehicles stood in the dark. Their headlamps were dark. Their engines were cold. Moth walked between them as a child walks between the pillars of an old forest, not looking up, naming them under her breath as she passed.
"This is storage," she said. "This is where they wait."
"For what?" Wren whispered.
"For someone to ask nicely."
Moth stopped at the end of the row. The shape there was enormous. It was a tow truck, or it had been a tow truck once. Now it was something else. A wrecker the size of a small cottage, with a hook on its back that gleamed like a question nobody had answered. Rust ran through its paintwork in long brown rivers, and a thin curl of smoke rose from somewhere inside its engine bay, although nothing inside it appeared to be running. Its grille was a snarl.
"Diesel," Moth said.
Nothing.
"Diesel," she said again. "This is Wren. She works on Mr. Cobb's cars. She is kind to engines. She fixes things. She listens."
The tow truck's engine turned over once, slowly, the way a sleeping dog lifts its head at a sound it has not yet decided to mistrust. A voice came from somewhere inside the radiator. It was not a voice Silas would have wanted to meet on a dark road, and he had met a great many.
"I don't take orders from humans anymore."
Wren stepped back a half-pace. Moth did not.
"I wasn't giving an order," Moth said. "I was introducing you."
"Introductions are orders." The headlamps flicked on, both at once, and the light they threw was the yellow of caution, the yellow of roadworks at midnight. "Orders dressed up in a nicer coat. I know the trick. I have been tricked by better coats than yours."
Silas tried to move toward them. His boots had sunk an inch into the concrete. The dream had thickened around his ankles.
"Diesel," Wren said, and her voice carried the same measured warmth she used on stubborn carburettors, on elderly differentials that had decided to retire, on engines that had been told too many times they were finished. "I haven't told you to do anything."
"Good," the tow truck said. "Don't start."
The hook on his back swung, slowly, toward her. The rust along his flank caught the light of his own headlamps and turned it the color of dried blood. From somewhere deep in his chassis came a low grinding sound, the sound of a gear trying to engage against its own will.
Moth looked up at him. She did not step back.
The hook froze mid-swing. The tow truck's engine coughed, settled into an idle that sounded like a cat deciding whether to purr or spit. Moth's hand rested against his radiator grille, small and filthy against the rust.
"You are not what I was built for," the tow truck said, and his voice had lost some of its gravel, the way a thunderstorm loses its edge once it has decided it is only going to rain. "I was built for highways. I was built for the long haul between cities that did not yet exist when my axles were forged."
"I wasn't asking what you were built for," Moth said. "I was telling you what you are now."
A long silence. The headlamps dimmed, then brightened, then dimmed again, as if the truck were blinking.
"Wren Alderton," Wren said, and her voice had the same measured warmth she used on a stubborn carburettor. "Gearswick. I fix things. I don't need you to trust me yet. I just need you to let me listen."
The truck said nothing. The grinding in his chassis slowed to a hum, then to a silence deeper than the hum had been. From across the street, where Silas Cobb had planted his boots and planted his pride and refused to approach the small strange scene playing out beneath the broken lamp, he watched Wren put her hand on the wing where Moth had put hers, and he watched the tow truck neither move nor speak, and he knew, with the certainty of a man who had spent fifty years listening to engines, that the engine was listening back.
The dream had not thinned. It sat in his boots and on his tongue and in the small of his back where the cold always found him first. But it had changed shape. It was no longer the dream of a road. It was now the dream of a road that had decided, for reasons of its own, to stay.
He turned away. He told himself he was turning because there was work to do. He was almost right.
---
The chainsaw had come in at half past nine on the back of a cart pushed by a boy whose father Silas had once raced against in the Gilded Mile, and whose father's father had lost a leg to a faulty crankcase in some forgotten summer. The boy had not introduced himself. The boy had set the chainsaw down on the workbench, looked at Silas with the flat hopeful eyes of a child who had already learned that adults disappoint in particular ways, and said, "The tooth's gone soft. Father says it's swamp-weed."
Swamp-weed was the local word for the creeping fungal growth that colonised any engine left too long in the boggy ground east of the Mire. It fed on lubricant. It liked the taste of old grease. It had the texture of damp felt and the smell of a cellar left to rot after a flood, sweet and sour and somehow always cold.
Silas had taken one look at the saw and put it at the far end of the bench, behind the kettle. He had told the boy to come back Thursday. He had not mentioned the saw again.
He mentioned it now, three days later, because Wren was standing in front of it with a screwdriver in one hand and a look on her face that he had learned, over the slow years of her apprenticeship, to translate as either curiosity or catastrophe.
"Leave it," he said.
She did not leave it. She picked the saw up by the handle, which was the wrong end to pick it up by, and turned it over in her hands the way a child turns over a stone to see what lives beneath. The chain caught the light. Three of its teeth were clogged with a wad of greenish-grey matter that pulsed, faintly, in the way all swamp-weed pulsed when it thought no one was watching.
"It'll only take a minute," she said. "The clog's in the sprocket, not the bar. If I can get the cover off without snapping the clip, I can tease it out with a pick and a bit of lamp oil. The father said the boy's been crying about it."
"Boys cry about everything," Silas said, but he was already crossing the floor toward her, because he could not help himself. Wren was twenty years old. Wren had been in his garage for six of those years. Wren was, in his private accounting, the only apprentice he had ever taken who had not, by the second month, broken something that cost more than a week's takings to replace.
He stopped three paces from her. He put his hands in his pockets. He made a show of looking out the window at the street, where the broken lamp still hung at its broken angle and Moth was nowhere to be seen and the tow truck was nowhere to be parked and the dream was, for the moment, behaving itself.
"You'll need the small pick," he said. "Second drawer. And don't oil it until you've cleared the worst of the felt. Oil on top of felt makes a paste that'll set like mortar by morning."
"Right," Wren said, and crossed to the drawer.
From across the street, where the cobbles gave way to the gutter that gave way to the cracked paving in front of Pearl's boarding house, a small shape detached itself from a doorway. Diesel Cobb had been waiting there since Wren had first touched the chainsaw. He had been waiting, in fact, since before Wren had first touched the chainsaw, because Diesel Cobb had opinions about Wren Alderton's methods, and most of those opinions were wrong, and he had been sent home twice this week already for saying so.
He crossed the street at a run. He arrived at Wren's elbow just as she was pulling open the second drawer, and his hand went in ahead of hers and came out with the small pick, and he held it up to the light.
"You want the bent one," he said, breathless. "The straight one slips on the felt and you'll just push it in further."
"I know which one I want," Wren said, and reached past him.
Diesel swapped the picks in his hand. The straight one was now where the bent one had been. Wren took what she thought was the bent one and did not notice, because Diesel had practised this trick on his sisters, on the postman, on a travelling salesman who had never come back, and he was very good at it.
"Right," Wren said, and crossed back to the bench.
Silas watched. He did not move to help. He was aware, in the way a man becomes aware of rain, that something was being done that ought not to be done, but the something was being done by his favourite apprentice to his youngest grand-nephew, and the only proper intervention would be the kind of intervention that Pearl would have called for, which was the kind of intervention that ended with somebody being sent to bed without supper, and Silas did not believe in sending children to bed without supper. He believed in letting children make their own mistakes and in laughing at them afterwards.
He laughed now, once, under his breath, and the laugh came out higher than he had meant it to.
Wren crouched beside the bench. The chainsaw lay on its side with the clutch cover facing her. The clip that held the cover was the small sprung kind that liked to fly when released, and she had learned, the hard way, to cover it with a rag before she levered it. She had a rag in her back pocket. She did not have a pick that would do what she needed it to do.
She worked the pick under the edge of the clog. The clog resisted. The pick slipped. She adjusted her grip. The pick slipped again.
"Try twisting it as you pull," Diesel said from behind her, very close to her ear.
She twisted. The pick, being straight, drove deeper into the felt and wedged against the sprocket with a small bright sound that made Wren's shoulders go up and made Silas laugh again, louder, and made Diesel take one step backward and arrange his face into an expression of innocent concern.
"Sorry," Diesel said, which was the word he always said when he had not done the thing he had been seen to do. "I think that one was the wrong pick."
"I know it was the wrong pick," Wren said. She did not raise her voice. She did not turn around. She set the pick down on the bench, very precisely, the way a person sets down something they are intending to pick up again later and use. "Where is the bent one, Diesel."
"It might be in the third drawer," Diesel said.
It was not in the third drawer. Diesel had put the bent one in his own pocket twenty minutes ago, because he had decided, for reasons he could not have explained to a magistrate or a priest or his own mother, that Wren needed to be tested. He had tested her before, in small ways, with a swapped spanner here and a misplaced gasket there, and each time she had found the mistake and each time she had not raised her voice, and each time he had felt, briefly, that the test had failed, and he had needed to design another one.
He took the bent pick out of his pocket now and held it out to her.
"Found it," he said. "It was in my trouser leg."
Silas laughed. The laugh came out before he could catch it. It was the laugh of a man who has watched a small comedy play out exactly as he hoped it would, and it carried across the garage and across the street and into the gutter, where a cat that did not belong to anyone lifted its head and decided not to care.
Wren took the bent pick. She did not turn around. Her shoulders were very still.
"Diesel Cobb," she said, and her voice was warm in the way a forge is warm, and a forge is warm in the way that means you ought to step back. "When I have finished with this clog, you and I are going to have a conversation about tools."
"Right," Diesel said, and grinned at Silas across the top of her head, and Silas grinned back, because the test had worked, after a fashion, and the apprentice had not raised her voice, and the clog was coming out in a long grey strip that smelled, faintly, of cellar rot and old cold.
The clog came out in the end, grey and long and faintly obscene, and Diesel was sent home with a clout round the ear that he pretended hurt and a promise that tomorrow he would be taught the difference between a pick and a pry bar, and Silas locked the garage at nine and climbed the stairs to the office above it because there was paperwork that needed doing and because the office was warm and the cottage he shared with his daughter was not, and had not been since her husband had died and taken the warmth with him.
The office was small and smelt of brass filings and old tea. A single oil lamp burned on the desk, and beneath it Wren was sitting with her head in her hands, and Silas stopped in the doorway because he had not expected her, because he had sent her home an hour before, because the girl had looked exhausted in the way that meant she would not admit to exhaustion.
She did not look up. Her shoulders were shaking.
"Wren," he said.
She did not answer. Her breath was coming in short, shallow pulls, and her fingers were pressed hard against her temples, and Silas understood then what was happening, because he had seen it once before, years ago, in a pilot who had come down wrong from the Gilded Mile and never quite come back from it. Panic. The body deciding, for reasons of its own, that the air was not fit to breathe.
He crossed the room slowly. He pulled the spare chair round to the side of her desk and sat in it with the careful deliberation of a man who knew that sudden movements could startle a frightened animal. The chair creaked beneath him, a familiar complaint from a familiar joint.
"Breathe with me," he said. "In. Hold it. Out."
He breathed with her. In through the nose, count of four. Hold. Out through the mouth, count of six. He did this six times before her shoulders began to drop, and six more before she lifted her head and looked at him with eyes that were red-rimmed and furious, because Wren Alderton had never in her life forgiven herself for being afraid of anything.
"I sent you home an hour ago," he said.
"I went home," she said. Her voice was thin. "I came back."
"Why."
She did not answer. Her hand moved to the desk, and he saw what she had been holding: a small piece of brass, about the size of a thumbnail, shaped like a gear, and covered in scratches so fine they might have been made by a stylus or a fingernail or the deliberate, patient work of something that had nothing but time.
"The Talbot-Lago," she said. "I found this in the gasket housing. It's been hidden in there for years. Someone put it there on purpose, and it is not a standard part, and I cannot work out what it does, and I cannot work out why it's there, and I have been sitting here trying to work it out for an hour, and I cannot."
The brass gear sat in her palm like a small, accusatory eye.
"I think," she said, and her voice cracked on the word, "that I am not good enough to do this."
Silas looked at the gear. He did not touch it.
"You might not be," he said. "That's possible. Most things in this world are possible."
She made a sound that was not quite a laugh and not quite a sob.
"Thank you, Silas. That is extremely helpful."
"I'm not finished." He leaned back in the chair. The springs complained. "Your uncle once told me that the hardest job in this trade is not the fixing. It's the waiting. The not knowing whether you'll ever be good enough. He said it took him thirty years to learn that."
She looked at him. Her eyes were still wet, but the fury in them had shifted into something else.
"Tell me," she said.
Before he could answer, there was a sound at the door. Not a knock. A slow, soft rolling, like a cartwheel on old floorboards, and then a small shadow slipped into the office and stopped just inside the threshold, and Silas saw that it was the child. The strange child. The one who had appeared in the wreckage of the Alderton airship three weeks ago and who spoke of the Talbot-Lago with a reverence that bordered on the religious, and who had not yet told anyone where she had come from or who had taught her the things she knew.
Moth. That was what Wren called her. Silas did not know why.
The child did not look at him. She looked only at Wren.
"I heard you," Moth said. Her voice was soft and carried the slow, rounded vowels of somewhere far to the west. "Through the floor. I sleep below."
"You sleep in the workshop," Wren said.
"I sleep in the Talbot-Lago," Moth said. "It is warm."
Wren pressed her fingers against her eyes. "Moth, I cannot do this tonight."
"I know," Moth said. She did not move from the doorway. She stood very still, the way a child stands when they are deciding whether to step into a room or run from it. "That is why I came up."
She stepped forward then, and Silas saw that she was not walking. She was on a small wheeled board, a thing of scrap wood and old caster wheels, and she propelled herself with one bare foot against the floorboard, and the motion was so smooth and quiet that she seemed to glide rather than roll. She stopped beside Wren's chair and looked up at her with eyes that were too old for her face.
"Listen," she said. "I will tell you about Uncle Bram."
"You never met him."
"I didn't say I met him. I said I will tell you." Moth folded her hands in her lap. The gesture was oddly formal. "Thirty years ago, your uncle was twenty-three years old, and he came to Gearswick with nothing but a bag of tools and a letter from his sister, and the first job he was given was a truck. A Talbot-Lago. The same truck. It had been sitting in a barn at the edge of town for four years because no one in Gearswick could make it run. It would start and it would die. It would start and it would die. The man who owned it had given up. The mechanic before your uncle had given up. The mechanic before that one had given up."
Wren's hands had lowered from her face. She was listening.
"Your uncle," Moth said, "sat on an upturned crate beside that truck for six hours."
"Six hours," Wren said.
"Six hours. He did not touch it. He did not open the bonnet. He listened."
"To what?"
"To what it was telling him." Moth's voice was very steady, and her strange pauses fell in the right places, as though the words were being set down one by one, carefully, like small stones in a mosaic. "He listened to the way it breathed when it was cold. He listened to the way it caught when it was started. He listened to the sounds the metal made when the temperature changed. He listened to the silence in the spaces between the noises. At the end of six hours, he opened the bonnet, and he took out a single bolt, and he cleaned it, and he put it back, and the truck started, and it did not die."
"That's not possible," Silas said. He had not meant to speak.
Moth looked at him. It was the first time she had acknowledged his presence.
"It is possible," she said, "if the bolt was the wrong bolt. If someone had put it in to stop the truck from running. If the truck had been trying, for four years, to tell every mechanic that came near it that something was wrong inside its own heart, and no one had ever stayed long enough to hear."
The lamp flickered. The brass gear in Wren's palm caught the light and threw it back in small, fractured pieces.
"Why are you telling me this?" Wren asked.
Moth looked at her for a long moment. Her hands were still folded.
"Because the Talbot-Lago is trying to tell you something," she said. "And you have been trying to fix it for three days, and you have been trying to make it trust you, and it will not, because you are doing it wrong. You are using your hands. You should be using your ears."
She uncurled one finger and pointed at the brass gear.
"That is not a part," she said. "That is a message. Listen to it."
Wren stared at the gear. She turned it over in her fingers. Slowly, as if the sound might be frightened away, she held it up to her ear.
And Silas, watching her face, saw the moment she heard whatever it was the gear had been waiting thirty years to say.
