The diesel arrived first, a low grinding rumble that shook the lighthouse walls and sent a thin line of dust cascading from the support beams overhead. Sable watched the particles drift through the grey morning light filtering between the louvered shutters and landed on the half-assembled manifold she'd been holding, one bracket still cold under her thumb. Rain hammered the copper roof in irregular sheets, the whole structure groaning and settling the way it did whenever the wind off the harbour shifted direction. Thursday. She remembered because Calla had scheduled the pressure-test of the third cylinder for Thursday, and the calendar was pinned to the bulkhead with a rivet that Sable kept threatening to replace. She never did. The rivet was fine. The rivet was a lot of things in this lighthouse.
The rumble grew teeth. Gears clunking through the gearbox with a rhythm that sounded wrong, too heavy, like a man dragging a chain across packed dirt. Then the front bumper of the Conventional cleared the dockyard gate and the whole workshop shuddered, the lighthouse's old foundation settling a quarter-inch against the bedrock. Sable set the bracket down on the workbench without looking at it, the metal still holding the warmth of her palm, and walked toward the ramp door.
The truck took up half the yard. Twenty-eight feet of steel and rust, a Conventional with a flat-nosed cab that still had its factory paint chipped down to grey primer along the lower fenders. Rain ran in grey rivers down the windscreen. The engine was idling, or trying to, because the cadence was broken, a stutter every fourth revolution that made the whole chassis shiver. Sable could hear it through the sole of her boots, a thump-thump-thump-pause, thump-thump-thump-pause, the rhythm of a thing that was running on fumes and stubbornness.
The driver's door scraped open. A step down, and a man appeared who was not what she'd expected. Rook. She'd heard Calla talk about him in the way people talked about ghosts, as a fact of the layout rather than a living person, but this was a solid, twenty-six-year-old man with shoulders that filled the cab frame and hands so wide they looked structurally unsupported. He stood in the rain with his jacket unbuttoned, a thin work shirt underneath that was already dark with moisture, and he looked at the lighthouse the way a dog looks at a new kitchen. Carefully. Like the thing might bite.
"Oi." He said it low, gravel at the bottom of the word, a northern drawl that flattened vowels and swallowed consonants. His voice was soft for a man that size, almost a murmur, and the rain nearly swallowed it. "She's throwing codes."
Sable wiped her hands on a rag tucked into her belt, the cloth already black with transmission fluid. "Which ones."
"Fourteen. Sixteen. And one I don't have a name for." He jerked his chin toward the cab. The OBD port was beneath the dashboard, and she could see the tail of a scan cable dangling, still plugged in, the LED blinking a rapid, confused amber. "Tried the shop in Thornwell. Three of 'em. None of the readers got the new map. Just spat back a generic misfire and told me to clear it and drive her gentle."
"Drive her gentle." Sable said the words flat, tasting the absurdity. "You've been running her through a rainstorm on a four-cylinder stutter for four hundred miles to get here."
"She holds together. Mostly." He pulled a rag from his back pocket, the kind that had been in the pocket so long it was practically a different colour, and wiped the rain from his lower lip. His hands, when he did that, were enormous, the knuckles scarred with old weld burns, the fingernails black to the second half-moon. "Six years, this rig. Drove her like a good dog. Fed her right, oil on schedule, filters on time. She never coughed on me before."
The last part came out quieter than the rest. Not sad, exactly. More like a man reporting a number to a ledger. Sable filed it away without marking it. She'd learned, working out of the lighthouse and the rooftop routes between, that a man's flat delivery meant the thing underneath was not flat at all.
She walked around the Conventional's nose, trailing her fingers along the intake manifold. The metal was cold, which was wrong. Cold in this rain, after four hundred miles of running, meant the coolant was circulating poorly or not at all. She pressed her ear to the block. The diesel was knocking, a wet wooden thud buried under the exhaust, and the idle pulsed with a lurch that made the whole truck list two degrees to port. She pulled back and looked up at Rook, who was standing under the cab's shadow, hands in his pockets, watching the lighthouse rather than the truck. Watching the building itself, the rivets, the old copper, the way the rain sheeted down the brick.
"You've been here before?" she asked.
"No. Called ahead. Tell me you're the one with the hands that can read a map the scanners don't." He said it without looking at her, and the sentence came out in one piece, no pause, the gravel in it smoother than before.
"I'm the one with the hands that can read a map the scanners don't, yeah." She patted the workbench through the ramp door, a gesture that meant come in, get out of the rain, stop looking like a man who's been standing in the Atlantic for three hours . "You can idle her there or kill the engine. Your choice. I'll need the cab open if I'm pulling the rail."
He killed the engine. The silence that followed was sudden and vast, the rain filling every frequency the diesel had been occupying, and Sable heard the lighthouse settling again, the copper ticking as it cooled, the harbour somewhere below the dockyard making its low, salt-stained exhale against the pilings. Rook wiped the windscreen with the same black rag, the motion slow, deliberate, each pass of the cloth in the same direction, left to right, left to right. A habit. A small, repeated thing that said I will make this clean before I let anyone else touch it.
He followed her up the ramp. The workshop smelled of machine oil and the particular dusty sweetness of old wood, and Sable could feel the damp on her own skin, a cold film that would take an hour to burn off. She pulled a stool from the rack and set it beside the lighthouse's central pillar, a column of riveted iron that had held the old lens mechanism before Calla gutted the whole thing and rebuilt it into a frame for the warm engine. The engine's core sat on the pillar now, half-encased in copper sheathing, and it looked, in the grey light, like a heart in a ribcage. Rook stopped four feet away. His eyes went to the copper. His jaw worked. He said nothing.
"Pull up a chair, then." She was already unrolling a schematic from the bench, the paper stiff with age, the ink a faded blue-black. "I need you to walk me through what the codes did. Not what you think they mean. What they did . Fourteen made her limp at idle. Sixteen killed the secondary pump. And the one you don't have a name for."
"The one I don't have a name for makes her forget." He said it without inflection. He sat on the stool, his long legs folding, the chair creaking under the weight, and his ham-sized hands rested on his knees, palms flat, fingers spread wide. "She forgets the fuel cut. At full throttle, the injectors lose their pattern for maybe two, three seconds. The needle lifts, the pressure drops, and for a heartbeat she's running on nothing. Then she catches. If the catch is clean, you never know. If it isn't, she stalls mid-corner and you're sideways in a lane of traffic."
Sable's pen stopped moving above the schematic. The rain intensified, a harder slap on the copper roof, and the sound of it made the lighthouse rings, a high, thin note from the old lens housing two floors up. She looked at Rook. He was watching the engine on the pillar, not at her, his expression flat and tired in the way that meant he'd been driving through the night and the rain had not been the first thing that had been hard this week.
"Two to three seconds," she repeated.
"Sometimes four."
"That's not a code. That's a fault in the timing circuit. The injector map is dropping out and re-locking." She tapped the paper. "Which means the ECU is seeing a ghost signal. Something's feeding it a clean read when the line's open."
Rook nodded once. "I was going to say the same thing except in less words and more cursing."
A sound escaped the back of her throat. Not quite a laugh. More a small, sharp exhalation through the nose. He looked at her, and the flatness in his face shifted, just a degree, a warping, like a gear meshing a half-tooth wrong. Then it was gone. He leaned forward and put both palms flat on the schematic, the paper buckling under the weight, and his fingers traced the timing diagram with a careful, sliding motion. The knuckle scars caught the light.
"Here," he said, pointing at a junction where the fuel-cut relay met the secondary pump controller. "This line. In the old grid they used a mechanical fail-safe. A spring-loaded contact. If the signal dropped, the spring closed the circuit and the pump kept running until a human reset it. This ECU doesn't have a spring. It just... lets go."
Sable looked at the diagram. Then at the engine on the pillar. Then at the diagram again. The warm engine was supposed to solve the heating problem, a machine that could keep a district warm through a frost that never ended, and every component had been rebuilt from salvaged parts, each one carrying the ghosts of its previous life. She understood, in the bone-deep way that lived in her hands rather than her head, what he was pointing at. The spring. The human reset. The small, stupid, essential piece that no scanner could read because it was not electrical. It was mechanical. It was a wire and a weight and a gap, and it was the one thing that said when the signal dies, something catches you.
"You want to build one," she said. Not a question.
"I want to put a spring on this thing before it eats itself on a hillside in February." He said it the way you'd say I want a cup of tea , flat and final, the sentence a door that had already been closed. "And I want to do it in this shop, on this bench, because the only other place in Thornwell that'd fit a Conventional under a lift is a yard that charges by the mile and wants a deposit." He paused. The rain tapped the shutters. "Calla's the one who answered the phone. I wasn't sure you'd be the one doing the work."
"Calla's the one who answers the phone," Sable corrected, "because she's the one who remembers the numbers. I'm the one who gets her hands in the guts." She rolled the schematic tight and set it on the engine block, pressing it into the copper sheathing so it would unroll flat against the surface. "But you came here for the right reason. The codes are a symptom. The fault is upstream. And I don't have the spring."
"No, you don't."
"So we make one."
He looked at her then, really looked, and the expression was the one she'd seen on his face standing in the rain, the careful, new-kitchen look, except turned inward. She read it as alright. You're the one I needed. And I didn't want to need you here. He said, "Coffee?"
"Black. Ugly. And you've got oil in your shirt that looks like a topographical map of somewhere I'd rather not visit."
He grinned. One corner. Quick. Gone. He stood, the stool groaning under the shift of weight, and walked to the lighthouse's back corridor where a battered percolator sat on a shelf above a sink that hadn't held water properly in a year. The percolator's plunger was loose, and when he set it down it rattled against the glass carafe with a sound like teeth clicking in a jaw. He ran the tap. Nothing. A thin, sputtering thread, then silence.
Sable watched him tilt the canister and shake, the ritual of a man trying to make a thing work that had quietly stopped working three years ago and nobody had told him. The rain was still on, a steady grey drum on the copper, and the lighthouse groaned its one low, structural note, and somewhere in the yard the Conventional's exhaust ticked as it cooled, a long, slow metal sound like a clock winding down.
"Pour what you've got," she said, pulling two mugs from the shelf. One was chipped. The other was a mug that said DUNMOOR MECHANICAL CORPS - PROPERTY OF THE CROWN in faded blue lettering, and the 'O' in CORPS was cracked through the middle. Sable set it on the bench in front of Rook without asking. He picked it up, his big hand wrapping around the ceramic, and the mug looked small in the grip, almost a toy. He drank. Winced. Set it down.
"Right," he said. "Spring."
"Spring."
He reached into his jacket pocket and produced a folded paper, the corners soft and grey with handling, and spread it on the bench beside the oil-stained schematic. It was a hand-drawn diagram, pen and ink, the lines dense and cramped, a single junction expanded into a full page of annotations. Arrows. Numbers. A small note in the margin, in handwriting that was not his: M. - do not forget the gap. 2mm max. - M.
The initials were Mabel's.
Sable looked at the paper. Looked at Rook. The rain filled the silence between them, the lighthouse settling, the Conventional ticking in the yard, the percolator on the shelf rattling its one empty click. Rook's hand was still on the mug, the ceramic warm, the chipped rim of the other one catching the grey light. He did not look at the paper anymore. He looked at the engine on the pillar, at the copper sheathing, at the warm half-heart of the thing Calla had been building for two years in a lighthouse on the edge of a frozen city.
"The gap's two millimetres," he said, and his voice had gone back to the low gravel, the murmur that the rain nearly took. "And when it breaks, there's no spring to close it. And she forgets. And you're on the highway at ninety with the injectors in the wind." He set the paper down. Both hands flat on the bench, the scars catching the light. "I've been driving her for six years, Sable. I know the knock. I know the lurch. I know the silence between the catches. But I can't fix what I can't read."
She picked up the chipped mug. Drank the cold, bitter residue at the bottom. The taste was metal and old water, and the mug was warm from his hand, and the lighthouse was shaking, the rain was a wall of sound, and the Conventional in the yard was cooling and ticking and forgetting, the way it did, the way it had been doing for six years, the way a dog forgets the name of the house it was raised in when the lights go out and the heating cuts and the cold creeps under the door.
She set the mug down. Picked up a bolt. Held it in her palm, the hex faces cold, the threads worn.
"Then we build the spring," she said. "And we read the silence."
The third hour arrived the way the rain arrived, slow and then all at once, and Calla's fingers had gone white from the cold at the edges of the loaf she held. The bread was stale in the way that only a long coast wind could make it, the crusts brittle as dead leaves, the crumb dense and grey with the salt in the air. Rook tore his piece with the jagged patience of a man who had once used hydraulic pliers to open jammed valve covers, and the snap of the crust echoed off the lighthouse wall behind them. Neither of them chewed quickly. The bread was punishment, but a small one, and the rain had a rhythm to it that made chewing a kind of metronome, and so they worked through the loaf in time.
The mugs sat between them on the tailgate's metal lip, the ceramic rims chipped in matching places, the coffee in them black and thin and long past the point of warmth. Rook's had gone to a cold residue at the bottom, the way the last sip of a forgotten cup tastes of the cup itself, of mineral and old enamel. Calla kept hers tilted, letting the thin stream run down the inside of her jaw, the bitterness a small clean blade.
The Conventional ticked in the dark of the yard. Not the angry tick of a seizing bearing, not the desperate stutter of an injector losing its timing. A lower sound than that. A slow, wooden creak, the way a floorboard in an empty house creaks when the wind shifts and nothing else is there to move. The engine-spirit was in the block, in the copper-sheathed cylinder head, in the six cylinders that Rook had driven for six years and known the way a father knows the particular limp in a child's gait. And it was grieving.
Calla set her mug down. Pressed both palms flat against the tailgate's cold steel, feeling the metal pull the warmth out of her skin, feeling the vibration of the ticking travel up through the plate and into the bones of her forearms. She leaned forward, close to the engine's bulk, close enough to see the condensation on the block's flanks, the faint blue sheen of old oil still weeping from a weep hole in the lower gallery.
"You carried her things," she said. Not a question. Her voice was low, the soft northern drawl she used only when she was working with something that didn't want to be worked, the way you speak to a horse that has seen a storm. "Cross-state. Cross-country. The last trip. And now she's in the ground and you're in my yard and the rain's getting into your breathers and you can't stop remembering the seat and the way she folded her coat and the way she tapped the window with one finger, just once, at each state line."
The ticking slowed. The wooden creak went quiet for two seconds. Then it resumed, softer.
Rook said nothing. He was looking at his hands, the scars on the knuckles catching the grey light, the old burns from a ruptured steam line in '09 mapped across the back of his left hand like a river delta. He tore another piece of bread. Did not eat it. Held it in his palm, the crumb crumbling over the scar tissue.
"She sat in the passenger seat," he said. His voice was the low gravel, the murmur that the rain nearly swallowed. "Every state line. One tap. And I'd say 'Mabel, hold on to the window, it's gonna be a hard patch between Kansas and the Missouri border,' and she'd say 'You talk to the truck like it's a dog, Rook.' And I'd say 'It is a dog. It's a very large, very stubborn dog that owes me six years of service and I'm not done with it.'" He set the crumb back on the torn half. "She died in the back seat. Two weeks before I walked out of the works. And I put her in the trunk and drove her to her mother's house in Ashfall and drove back with the lock still cold on the handle and the air still smelling like lavender soap and the particular dust that old wool throws up when you fold it."
The ticking stopped. The engine was silent. The rain filled the silence with its flat, indifferent wash over the lighthouse roof, over the yard, over the tailgate where they sat with their cold bread and their black coffee and the weight of a dead woman's lavender-tinged wool hanging in a dead man's memory.
Calla pressed her forehead against the tailgate's edge. The steel was cold enough to make her sinuses ache. She breathed into the metal, her breath fogging, clearing, fogging. "I'm not going to make you remember the fold," she said. "I'm not going to make you run the line again. I just need you to hold the block so it doesn't crack when I pull the head. Two millimetres. That's the gap. I'll machine the spring tonight. You just hold."
A long silence. The rain. The tick, starting again, very soft, very far away, like a clock in another room.
Rook nodded. Once. The bread in his hand went soft from the moisture in his palm. He ate it in one flat tear, chewing with the methodical patience of a man who had been chewing for forty years and had learned that bread was not the part you thought about.
Sable, four metres up on the hydraulic lift platform, had been watching them for the better part of an hour from the position she had claimed when she'd come down from the roof after her parts run, a crouch with her knees drawn up and her elbows on them, her chin in her hands, her dark hair plastered to her skull where the workshop heat had steamed it. She looked, from the tailgate's perspective, like a gargoyle that had been left on a drainpipe too long, all angles and bad posture, one boot swinging in a slow arc.
"You're gonna give me a cavity," she said, dropping the words down at them in the fast, clipped cadence she used when she was annoyed, the street-level rhythm that had never quite lost its edge no matter how many years she'd been off the rooftops. "Three hours, you two, on a tailgate in the rain, eating dry rye like it's a goddamn picnic. And the engine's been doing its little ghost show for forty minutes and you're just sitting there talking to it like it's a stray."
"It's not a stray," Calla said, without looking up. Her voice had that warm, measured quality, the one she used when she was explaining a load-bearing calculation to a client who wanted to know why his heating coil was going to burst, the tone that said I have patience and you will have it too if you sit still . "It's a Conventional. It has a name in the schematics. And it's not showing. It's remembering. There's a difference."
Sable's swinging boot stopped. She uncurled one hand from beneath her chin, let it hang, the knuckles scraped and red from where she'd been picking at a rusted bolt on the lift's frame. "Right. Remembering." A flat, dry sound. "So we just sit here while a lorry's soul has a nostalgia episode and the world freezes over and the warm engine's still got a two-millimetre gap in its most critical joint and we're all just, what, having a moment?"
"We've been having the moment for three hours," Rook said from the tailgate, and his voice had that sudden jolt to it, the gruff snap that came up like a pressure valve releasing, the gravel cracking against the low murmur. "And I'll be having it until Calla's got her spring machined and I've held the head steady and you've stopped swinging that boot because it's starting to sound like a tap on a cistern in a dead man's house."
Sable's boot swung again, slower now, the rhythm more even. She looked down at the tailgate, at the two of them, at the cold mugs, at the torn bread, at the rain that was pooling on the metal lip and running off the edge in thin, silver threads. The lighthouse behind them was a dark shape in the downpour, its lamp cold and dark, the converted structure standing against the flat grey sea like a clenched fist.
"You know what my cadet instructor used to say," Sable called down, the words tumbling over each other in that fast, urban stutter. "He said, 'The machine doesn't grieve, the machine forgets, and the only way to make a machine remember is to break it in a new place.' And I ran out of the Corps because I told him that was bullshit. And I was right. It was bullshit. The machine doesn't forget. It just doesn't get asked." She paused. The swinging boot stopped. She looked at the engine, at the Conventional in the yard, at the slow tick of its grief. "So you're asking it. You're asking it to hold. And it's holding. And that's three hours of the most expensive tailgate in Dunmoor."
Calla laughed. It was a small sound, quick, the kind she made when a calibration reading came in just right and she could feel the tolerances click into place, the sound of a person who was not used to the relief arriving in pieces. She pressed her forehead back against the cold steel. The rain was on her face, the cold running in thin lines from her hairline down her temples, and she did not wipe it.
"Two millimetres," she repeated, to the engine, to Rook, to the rain. "I'll have the spring by nightfall. You hold the head. And the Conventional, you hold what you remember. You don't have to drive it again. You just have to not let the block crack."
The ticking started. Slow. Even. The sound of a heart that had been running for a long time and was learning, in the cold and the rain and the three hours of a woman's quiet, warm voice, to slow down enough to bear one more weight.
Sable swung her boot once more. Then she leaned back against the lift's frame, the metal groaning under her, and closed her eyes. Above her, the rain hit the lighthouse roof in a sound like static, like a radio tuned between stations, like the particular silence of a city that was freezing over, one degree at a time, and the warm engine was not yet built, and the gap was still two millimetres wide, and the night was coming, and the mugs were empty, and the bread was gone, and the three of them were still in the rain, and the ticking was the only clock that mattered.
Below them, on the tailgate, Rook reached into the wet pocket of his work jacket and pulled out a square of paper, folded to the size of a cigarette. He did not open it. He set it on the tailgate's lip, next to the cold mug, and watched the rain flatten the creases, watched the ink run, watched the words he had not read in six years dissolve into grey. Then he picked up his chipped mug, turned it over, and let the last cold drop fall onto the tailgate, a small dark spot in the silver water.
"Two millimetres," he said, to no one, to the engine, to the rain. And the ticking held.
The rain found the gap between Rook's jacket collar and his neck and he shivered, a full-body convulsion that rattled his teeth. Sable watched him do it from the lift's crossbar, her elbows tucked into her ribs, her boots swinging over the tailgate's edge into the grey water two feet below. She smelled wet wool and the copper tang of blood from where she'd split her lip an hour ago against the engine housing. The ticking went on. Slow. Even. Two millimetres of silence inside the warm engine, and the sound of the piston striking its housing on every other revolution.
"Gap's the same," Calla said. Her voice came from below the tailgate, muffled by the lighthouse's corrugated wall, but Sable caught the words. Calla was crouched in the workshop's lower bay, her headlamp a thin white wedge cutting through the curtain of rain, her hands deep inside the engine's casing. "Still two. I've shifted the housing a quarter-turn clockwise and the clearance is the same. Either the bore is scored or the piston is out of true and I can't tell which until I strip the block."
"You can't strip the block in the rain." Rook said it flat, to the lighthouse wall, as though the wall owed him an answer.
"I can if I hold the housing with one hand and reach with the other." Calla's headlamp swept. Her shadow crossed Sable's boots. "Give me twenty more minutes."
Twenty more minutes. Sable counted them on her fingers, the way she did when the cold got into her joints and she needed something mechanical to hold her attention. Twenty minutes of rain on the lighthouse roof, a sound like a thousand small teeth chewing on metal. Twenty minutes of Rook sitting on the tailgate, his chipped mug long dry, his hands wrapped around it like a man holding a dead bird. Twenty minutes of the ticking.
She swung her boots again. The water below the tailgate was silver and still, disturbed only by the fall of rain, and in the pause between drops the lighthouse's silhouette was a black finger pointing at a sky so thick and low it had no colour at all.
"Rook." Sable's voice came out faster than she meant it to. A sharp bark.
"Hm."
"You're sitting here in the rain holding a dry mug like it's a goddamn reliquary."
"It's the last mug."
"It's chipped. I saw the chip. You've got tea in a chipped mug in the rain and you're not drinking it."
He turned it over in his hand, studied the rim, and set it down on the tailgate's lip with a soft clink. "Ain't tea. It's rain. Got water from the eaves an hour back." He paused. The ticking went on behind them, in the wall, in the engine, in the space between the piston and the bore. "What's the difference."
"That's not a question."
"No. It's a statement. And it's a true one." He said it the way he said everything, low and flat, like a man reading a weather report from a station that hadn't updated in weeks. "You can drink rain or you can drink tea. The cup's the same. The cold's the same. The fact that you're sat in it is the same."
Sable almost laughed. The rain in her hair was cold, stinging the parting along her scalp, and she wiped it back with the heel of her palm. Almost laughed, and then didn't, because the almost was a thin membrane and underneath it was something she did not want to name while Calla was in the engine and the gap was still two millimetres and the night was twenty minutes from falling.
Instead she said, "You're done."
Not a question. A statement, matching his. She leaned forward, her boots finding the crossbar, and looked down at him. The rain ran in a line down her jaw and she did not blink.
"I'm done hauling. I'm done with the scrap. I'm done driving the truck into the district, finding a pallet of gearbox housings that weigh four tons and rust through the base plate, and loading them into the back because some bloke in a wool coat told me to, and then unloading them into a yard where they'll sit in the frost another six months." He said it in one breath, the way a boiler releases steam, all at once, the pressure building for years and then just gone. "I'm done. End of the month. I hand in the keys and I walk away and I don't know what the bloody hell I do with the rest of it."
The ticking.
"Rest of it." Calla's voice came up through the lighthouse wall, muffled, still working. "Rest of what, Rook?"
"Rest of me. That's what." He held the dry mug by the handle, turned it a quarter-turn. The rain filled the gap where the tea had been. "Six years. Six years I've been hauling scrap for the district, loading and unloading, driving the same route, same roads, same frost on the same glass. And it was because of Mabel. That's what I was doing. Keeping the truck moving because if I stopped moving I'd sit in the workshop and look at the schematic board and remember where the pressure valve was and I'd open it and I'd feel the grid and I'd hear Mabel's boots on the catwalk and I'd call out a number and nobody'd answer because she was dead and the grid was dead and the number didn't matter. So I drove. I drove and I loaded and I unloaded and I didn't look at the schematic board. Six years."
The rain hit the tailgate in a hiss. Sable watched the water sheet down the metal, watched it pool in the lip where Rook's mug sat, watched the mug's dark ring slowly dilute into the silver.
"So what do you do?" Calla asked, and her voice was not muffled now. She had emerged from the lower bay, crawling up the internal ladder, and she was on the workshop floor three feet away, her headlamp cutting a cone of white across the three of them. Her face was streaked with engine grease and rain, her hair plastered to her forehead, and she was looking at Rook with the specific, exhausted, irritated tenderness of a woman who had just spent twenty minutes reaching inside a machine in a downpour. "You say you're done. Six years of not looking. What's the next six?"
Rook did not answer. He set the mug down. He picked up the square of paper from the tailgate's lip, the one the rain had already eaten, and he held it up between two fingers. The ink was a grey smear. He looked at it for a long moment, then folded it in half and tucked it back into his wet jacket pocket. The pocket had already lost whatever it had been protecting.
"I don't know," he said. Two words. Low. Gravel. "I don't know what I do with a man who's spent six years not looking."
"You could just stay," Calla said.
It came out fast. Unthinking. The words left her mouth before she had shaped them, before the grease on her hands had wiped off, before the rain had stopped hitting the roof. She looked at Rook, and he was looking at her, and the two-millimetre gap in the engine behind them ticked on, and the rain was the only other sound, and she heard herself say the words back to her own surprise.
"There's a bunk under the shop. I've got a quilt, a thermos, a tin of tinned beans that's three winters old. You don't have to haul anything. You don't have to drive anything. You just have to sit here and look at the schematic board and tell me where the pressure valve is and whether the bore is scored or the piston's out of true, and I'll do the stripping, and you don't have to stop moving because you can move a wrench, and it's not the grid, and it's not Mabel's boots, and the number matters because it's a clearance I can measure."
She stopped. The rain hit the roof. The ticking went on.
Rook blinked.
Not a quick blink. A slow one, the kind that took four seconds, the kind where the lower lid crept up and the upper lid came down and the whole face went still in the middle, the way a man does when a sound reaches a part of him that was not expecting sound. His hands were in his lap. The mug was in his left hand. He did not set it down.
"Yeah," he said.
The word was small. It was the size of a pin, a single point of pressure on the rain, on the ticking, on the two millimetres of gap in the engine behind them.
"Yeah," he said again, louder, and he set the mug on the tailgate, and he looked at Calla, and his face was a wall with one window open, and the window was the size of a pin, and through it you could see the whole of him, the six years, the catwalk, the number, the silence after the number. "Yeah. I'll stay."
Sable swung her boots. One time. The water below the tailgate churned, and the lighthouse's shadow shifted in the dark, and she said, "Alright. That's the best thing I've heard in a week, and I'm counting on it not being a bad thing."
"It's not a bad thing," Calla said. She was already moving, pulling the lower bay's curtain aside, the metal rings singing against the lighthouse's ribs. "I need you to hold the housing steady. Left hand, here. The bore. If the piston's out of true you'll feel a drag at the two o'clock position."
"Two o'clock." Rook was already on his feet. His joints cracked, a dry sound under the rain. He took the housing, and his hands found the metal, and his fingers closed around it with the easy, practised pressure of a man who had held a thousand housings, and he said, "Two o'clock. I'll hold."
Sable watched them work. Calla on one knee, the headlamp strapped under her chin, her hands inside the engine's chest, pulling the piston free. Rook on the other side, bracing the housing, his shoulders squared, his breath fogging in the cold air of the workshop. The piston came out with a wet, sucking sound, and Calla held it up, and the rain kept falling on the roof, and the ticking stopped.
The engine was silent.
"Scored," Calla said, into the silence. She turned the piston in the light of her headlamp. The bore showed a ragged line, a dark scratch running from the three o'clock to the seven o'clock position. "Not out of true. The bore's scored. I can ream it, but I need a reamer I don't have, and I need Sable."
Sable was already climbing down the tailgate, her boots finding the ladder rungs, the rain running down her neck, her split lip stinging. "Yeah, yeah. I know where the old Mechanical Corps yard is. There's a reamer in the east she'd, probably. Might be under a tarp. Might be rusted. Might be both." She said it fast, a single breath, and she was gone, swinging over the ladder's top rail, into the rain, into the dark.
The door closed behind her. The lighthouse was quiet except for the rain on the roof and the two of them, Calla and Rook, standing in the wet workshop, the piston in Calla's hand, the housing in Rook's, the two-millimetre gap closed at last by the simple act of taking the piston out.
"It'll take her twenty minutes," Calla said.
"It'll take her twenty minutes if the east she'd isn't flooded. If the tarp's there. If the reamer isn't a slab of rust she'll have to file down by hand." Rook set the housing in its cradle. He did not sit. He stood, and his hands hung at his sides, and he looked at the schematic board on the wall, and the board was blank, the old grid maps gone, the old numbers erased, and he looked at it, and his face did the pin-window thing again, and he said, "It was Mabel's board. The numbers were in her hand. She used to do the pressure callouts in red."
Calla was already reaching for the reamer box, a small metal case on a shelf above the bench. She opened it. Inside, wrapped in oilcloth, was a reamer, a long steel rod with a spiral cutting edge, and a second, smaller one, and a file, and a block of brass, and a spool of thin gauge wire.
"Reamer's here," she said. "I don't know why I've got it. I've had it since I was nineteen. I don't know why."
"Maybe you knew you'd need it," Rook said.
