The rain over the Harrowby Trade Estate was the kind of steady, gray northern drizzle that got into the seams of your jacket before you reached the trade counter. It beat a relentless, tinny tattoo on the ribbed roof of Ada Morland’s white Ford Transit van. That turned the gravel parking bay behind Unit 4 into a stew of diesel-slicked puddles and yellow clay mud.
Inside the cab, the air smelled of damp wool, radiator flux, stale tobacco from the last owner. The warm, yeasty crust of a thick sourdough crust sandwich wrapped in greaseproof paper on the dashboard. Next to it sat her green Stanley steel thermos, its stopper warm to the touch, venting a thin, comforting curl of steam that smelled of boiled tea and condensed milk.
Ada sat in the driver’s seat with the engine idling to keep the heater blowing a lukewarm breath across her boots. She was forty-three years old, with broad, square shoulders and weathered skin around her gray eyes from twenty-two years of kneeling on damp screed, crawling under Victorian floorboards, and breathing the sharp fumes of lead solder. Her dark hair was streaked with silver at the temples, pinned back into an unbending pencil bun with a two-inch brass hair-needle-point arrow.
She turned off the starting. The diesel engine shuddered once, then died into the quiet drumming of the rain.
On the passenger seat, Ada unbuckled her main check bag. An olive-drab canvas tool roll made of twenty-ounce waxed duck, double-stitched along the seams, with heavy leather buckle straps and solid brass eyelets.
She had spent half an hour at the trade counter drinking lukewarm machine coffee. She listened to two younger sub-contractors complain about plastic push-fit fittings that blew off. Just then, the water board pumped mains pressure above four bar. Ada hadn’t joined the conversation. If a tradesman trusted an unreinforced plastic grip-ring on a forty-pound live line, he deserved the sodden floorboards he had to rip up on Saturday morning.
She pulled out her kitchen balance from behind the passenger seat. A heavy, clockwork brass spring scale with a hooked steel eye at the bottom and an engraved face plate graduated in quarter-pounds. There was no battery in it. It worked on an oil-hardened steel coil spring that had been tuned against cast-iron test weights when her father ran the workshop in Bramley.
The rules from the Lowbank washroom were written on a scrap of cardboard tucked into her sun visor:
Maximum payload mass: 7.0 kg. Clockwork hand tools and sustenance only. No combustibles. No loose liquid fuels.
Ada knew what happened when an apprentice tried to cheat a load rating. She had seen an apprentice roofer try to take an extra bucket of slate nails up a light metal ladder rated for two hundredweight. The ladder had bowed, kicked out from the guttering. Then he put the lad in Leeds General Sickroom for six months with two shattered ankles. A limit was not a suggestion. It was a line drawn by gravity and physics, and neither of them gave an inch for an excuse.
Step by step, she emptied the canvas roll onto the passenger seat. She wiped each tool with an oily rag before selecting what went into the crossing kit.
First was the backbone of her trade: her ten-inch Bahco adjustable wrench. It was forged in Sweden from high-grade chrome-vanadium steel, its black phosphate finish worn away at the nose to reveal bright, silvery metal. The knurled adjusting screw had just enough clearance to spin with a thumb while wearing work gloves. But zero lateral slop when tightened across the flats of a brass union. One side of the reversible jaw was ground flat for chrome nuts. The other had serrated pipe-teeth that could bite into rusted through lead or iron without slipping.
She checked the jaw play, wiped a speck of copper green rust from the pivot pin. Then she slid it into the center canvas sleeve of the roll.
Weight: five hundred and fifty grams.
Second was her test eye. A clockwork brass dial pressure gauge, zero to one hundred pounds of pressure, with a backup scale in bar. The housing was solid cast brass, heavy and round, with a heavy beveled glass lens protecting the white enamel dial. It had a quarter-inch male thread at the base, cut with a standard British Standard Pipe taper. A knurled six-sided shoulder for wrench flats. Inside, there were no circuit boards, no thermistors, and no light-emitting diodes. It was purely a glowing-bronze Bourdon tube. A curved, hollow oval tube that straightened under pressure, turning a tiny clockwork brass side gear and hairspring that moved the black steel pointer across the numbers.
She held the gauge to her lips, blew a short puff of warm air into the threaded nipple. Then she watched the needle tick cleanly off the brass zero stop. She rose to half a pound before dropping back with a sharp, clockwork click.
Weight: four hundred and twenty grams.
Next were the consumables and packing materials. She packed three spools of heavy commercial PTFE thread tape. The thick, yellow-cased gas tape, zero point a tiny fraction of an inch thick. It could seal pitted iron threads that ordinary white domestic tape would shred against. Beside them, she laid a hank of unspun hemp tow and a small flat tin of linseed-oil pipe paste, its screw-lid sealed with wax. If the Lowbank under-road drains were built of Victorian-era lead and river stone, tape alone might not take the bite. Hemp tow soaked in paste was the only thing that could seal an out-of-round collar. Just then, the threads were eighty years old.
Weight: three hundred and eighty grams.
From the door pocket, she took her clockwork check tools: a nine-inch solid brass drift for tapping stuck pipe rim pins without causing a starting spark. A hardened steel scraper for cleaning scale and old pipe lime from joint faces. And an old German check torch—a solid brass metal tube with a knurled head and a heavy glass bullseye lens. She laid two clean cotton rags, boiled in lye and dried until they were soft as flannel, in the bottom of the roll to prevent the metal tools from clattering against each other.
She paused, looking at her yellow grease pencil. She had carried it in her breast pocket since her apprentice days on the Leeds hospital district heating circuit. A grease pencil wrote on wet lead, oily cast iron, glazed tile, or rough granite. It didn’t wash away in a bilge leak, and it didn’t smear when wiped with a thumb. She slipped two pencils into the loop beside the Bahco.
She rolled the canvas tight, wrapping the leather straps twice around the bundle and cinching the heavy brass buckle into the fourth hole.
Ada hooked the steel eye of the spring scale through the leather carrying handle of the bag. She stood in the narrow footwell of the cab. She lifted the scale until the canvas roll swung free of the seat cushions.
The steel pointer groaned against the brass faceplate, sliding down past five pounds, past six.
It trembled, bobbed twice, and settled dead true on six point two pounds.
“Six point two,” Ada muttered to herself.
She took her lunch from the dashboard. The sourdough crust sandwich with mature Cheddar and pickle, wrapped tight in greaseproof paper, and an English Russet apple. She shoved both into the side pouch of the canvas bag.
She lifted the scale again.
The needle moved down two marks, settling firmly on six point eight pounds.
Two hundred grams of safety margin. Exactly seven ounces of air between her load and the total threshold of the arch. If she picked up an iron bolt or a handful of river gravel on the other side, she would have to leave a wrench behind to balance the ledger.
She lowered the bag to the passenger footwell, wedging it securely against the signal tunnel so it wouldn’t roll if she took a corner sharp.
She sat back in the worn vinyl seat, picking up her thermos of boiled tea. The dark brew was hot, bitter, and strong enough to coat the back of her throat, warming her ribs through her flannel shirt.
She looked out through the rain-streaked side window at the gray expanse of the Harrowby Trade Estate. Across the lane, a flatbed lorry from a timber merchant was unloading wet spruce floor beams with a diesel forklift, the machine’s high-pressure rams whining under the load. In the office of Unit 2, her seventeen-year-old nephew Ben was sitting behind a drawing table. He leaned over clockwork height drafts for a heavy-duty drainage run in Bradford.
Ben had asked her last night. Meanwhile, they were frying sausages over the gas ring in the back kitchen, why she was taking on extra work. Just then, the council repair backlog was already running five weeks deep.
Because a council contract pays thirty-four pounds for an afternoon of snaking out blocked grease traps in high-rise flats, she had told him, and the council takes six weeks to process an invoice. The girl on the other side of that brass hoop has a lockbox of river silver that assays at forty-five quid on the spot, and she understands that a pipe doesn’t care about town committee meetings.
Ben had looked at her with his quiet, serious eyes—so like his mother’s before the pneumonia took her—and told her to make sure her boots were laced tight and to keep her hands out of ungrounded water.
Ada smiled faintly, unscrewing the cup from her thermos and draining the last of the tea.
She reached for her work jacket. A heavy navy blue drill-cotton coat with quilted shoulders and grease-darkened cuffs. She checked her breast pocket. Her clockwork wristwatch with its stainless steel spreading band was ticking steadily against her wrist. It had no quartz battery, no microchip, and no display screen. It ran on seventeen jeweled bearings, a mainspring wound every morning at six. A balance wheel that pulsed five times every second.
She reached into the glove box, pulled out a fresh roll of electricians’ tape. Then she taped her council identification badge flat against her breast pocket so the plastic laminate wouldn’t catch on anything.
She looked at the digital clock on the van’s plastic dashboard: 12:02 PM.
Thirteen minutes until her lawful forty-five-minute lunch break began. Thirteen minutes before she turned the key, carried the canvas bag into the rear bay of Unit 4. Then she saw what the other side of the brass hoop had to say about water pressure.
