The first bolt came out whole. The second brought half the wall with it.
Iven watched a fist-sized piece of masonry tumble through the bridge’s lower braces, strike a pipe, and vanish into the dark gap between the buildings. It struck something else on the way down. The sound arrived late, followed by a man’s voice asking who was throwing the city away.
“No one,” Neri called. “We found a loose piece.”
“Put it somewhere else.”
“That’s the intention.”
Iven leaned over the rail. The voice belonged to a mason carrying two buckets along the lower lane. Both buckets appeared intact, though the man had stopped in the middle of the walkway and was examining his shoulders as if expecting further deliveries.
“Sorry,” Iven called.
The mason raised one bucket in acknowledgment and continued. He did not thank them for the warning, which was fair. They had not given him one.
Neri ran her fingers along the torn bolt hole. The bridge’s far end rested on a steel shoe fixed to the old wall. During Mercy’s recent turn, the shoe had twisted. Her crew had brought longer beams and temporary support across the gap, leaving a route for two pedestrians at a time or a stretcher party. No carts. No crowd. The limit had held through yesterday’s test and through the night, but the old far bolts had to come out before she would call the crossing sound.
“There’s a pocket behind the face,” she said.
“That’s where the piece came from?” Iven asked.
“Probably. I’ll look before I promise.”
She tied a line around the rail, checked the knot, and lowered herself over the side. Iven held the other end around a sound post. The movement pulled at the sore place in his shoulder, but the pain had faded since the collapse, and the line’s load was light. Dessa stood beside him with a second rope, while Jem waited at the far wall with the replacement fasteners.
Below the bridge, a narrow gutter collected water from the roofs. Its cover had bent during the turn. The gutter ran past a shored building whose upper room had collapsed; the masonry there still bore marks from the rescue. A strip of blue cloth tied to a window frame indicated that the rooms beneath were occupied. Someone had set a pot of green shoots on the sill. Iven could not decide whether it was a hopeful sight or an accusation that the rest of the street ought to have done better.
Neri tapped the exposed wall with her hammer. A dull section answered behind the broken hole.
“Who filled this?” she asked.
Jem leaned out to hear. “Old work. Before mine.”
“Before the bridge?”
“Maybe. The shoe sits over the patch.”
Iven could see the difference now: a darker seam beneath the steel plate, covered by years of paint and soot. Whoever had installed the shoe had driven the bolts into a surface that appeared solid. Some of them had reached the original wall. At least one had found the pocket.
Neri put her weight against the line and angled her lamp into the gap. “Brick backing is sound farther in. We can bridge the pocket with a longer plate.”
“How long?” Iven asked.
“Long enough to get beyond both sides. Jem, measure from the third hole to the sound edge.”
Jem took out a folding rule. He measured, checked the far edge with the awl Neri passed him, and gave her the figure. Iven held the rope while she made a quick sketch against the wall with chalk.
The wind shifted. A smell of smoke came from the street beyond the shored building, followed by the sharp scent of something burning that should not have been in a cookstove.
Dessa turned first. “That’s too much smoke.”
A gray plume lifted over the roof. A woman appeared at the corner below, carrying a basket against her chest. She saw the plume and began to run. Another followed, dragging a child by the hand.
Neri looked up at Iven. “Get me up.”
He pulled. The winch pattern was seated, but he did not use it until her boots lost purchase against the wall. Then he drew against the post, adding a steady force to the rope while Dessa took the slack. Neri came over the rail and landed on the bridge with both hands free.
“Jem, keep the shoe supported,” she said. “Dessa, clear the far landing. Iven, with me.”
They ran toward the smoke. The bridge dipped a fraction under their combined weight and returned to its mark. Iven had no time to appreciate the workmanship. At the far landing, he nearly collided with a boy carrying a folded blanket. Neri caught the boy’s shoulder and steered him back toward Dessa.
“Tell her what’s burning,” she said.
“The washhouse stove,” he gasped. “The chimney fell inside.”
The washhouse occupied the ground floor of a long building whose upper windows had been boarded after the collapse. A row of tubs stood outside under a canvas awning. The canvas was already burning along one edge. Two people were trying to pull it down with a pole that was too short.
Iven seized the pole, climbed onto the nearest tub, and hooked the canvas. The tub shifted under his boots. He steadied himself with a hand against the wall and pulled. The fabric tore, came down in a burning fold, and landed on the wet paving. One of the washers threw a bucket over it. Steam rose around their legs.
“Inside?” Neri asked.
“A woman and her son,” the washer said. “The back door’s blocked.”
Smoke rolled from the open front doorway. Iven could see the stove just inside, its chimney pipe lying across a table. A stack of drying cloth had caught where the pipe struck it. The flames had not yet reached the far wall, but the smoke filled the upper half of the room.
The washer pointed down the passage between the buildings. “Back door’s there. The wall from the old storage room came down across it yesterday.”
Neri went toward the passage. “I’ll clear the exit. Don’t push them into the smoke.”
“I know.”
“I know you know. I’m saying it anyway.”
Iven pulled his coat over his mouth and checked the three patterns he had seated that morning: plate brace, spring step, and winch draw. The filter was in his library, not ready in a channel. He stepped into the doorway’s shelter, let spring step settle back, and drew the filter forward with his free hand. The change took several breaths. He kept his eyes on the room while he did it, because he had once tried to make a change faster than he understood and nearly walked into a wall.
The filter could take grit and smoke particles from a small volume of air. It could not make oxygen. It could not make the burning cloth harmless. He stayed low, tested one breath, and moved toward the stove.
The woman was beside an overturned tub at the back. She had her son under one arm and a wet cloth over his face. He was perhaps six, too frightened to stand though his legs seemed sound. The back door lay behind them, its lower half pressed inward by fallen blocks.
“Can you walk?” Iven asked.
The woman nodded. “He won’t leave the dog.”
The boy held a thin cord wrapped around his wrist. It disappeared behind the overturned tub. Iven crouched and found a small brown dog wedged between the tub and the wall. It bared its teeth at him, then coughed.
“Your dog has excellent timing,” he told the boy.
“He’s afraid.”
“So am I. We can all go together.”
Iven tried to lift the tub. Its rim had caught beneath a shelf, and the water left inside made it heavier than it looked. He put his shoulder under the edge, ignoring the complaint from the bruise, and raised it a few inches. The dog scrambled free and ran directly toward the front door.
The boy followed. His mother caught his coat before he reached the burning cloth. Iven thought of a piston push, then remembered it was not seated. He took the physical water bucket beside the stove instead, and threw it over the nearest flame. The cloth hissed and collapsed against the table. He did not need a new pattern for a bucket.
At the back door, something struck the fallen blocks. Neri’s voice came through the wood. “I’m opening the top. Stand clear.”
The woman moved the boy against the wall. Iven caught the dog’s cord as it circled back. The animal snapped at the rope, missed, and pressed against the child’s leg.
The top block lifted. A second slid away. Light entered through a gap no wider than Iven’s hand. He put his fingers through and felt Neri pass him a short line.
“Can you get this around the inside handle?” she called.
He tied it through the handle’s iron loop. Neri pulled from the other side. The handle tore free, taking a splinter of wood with it.
“That wasn’t the plan,” she said.
“It improved the ventilation.”
“Stand back.”
Iven heard the scrape of a lever. The upper door moved inward. A block dropped through the gap. He raised the plate brace over the woman and child, catching the block against its compact surface. The impact jarred his forearm. He directed the piece toward the floor, released the brace, and kicked it clear of their feet.
Neri forced the door farther. Dessa appeared behind her, holding the lever while Jem shifted the next block. The opening widened enough for the boy to crawl through. He went first, pulling the dog after him. His mother followed, then turned immediately to help him stand.
Iven started toward the opening and stopped. The table beside the stove had tilted. A pot on its edge held more water than the bucket he had thrown. He caught the handle with his hammer, pulled it down, and tipped it over the burning cloth. The remaining flame shrank to a dark, steaming patch.
Outside, the boy had his arms around the dog. The animal looked embarrassed by the attention. Its owner had soot across one cheek, and his mother was rubbing at it with a cloth that only made the soot larger.
“You missed a spot,” Iven told her.
“I’ll find it later.” She looked past him into the washhouse. “The clean blankets were in there.”
He followed her gaze. Some lay in a basket near the front wall, blackened at the edges but not burning. The roof above them was still sound. He and one of the washers went back in with wet cloths over their mouths and carried the basket out. Sera would know which blankets could be cleaned and which should be discarded. For now, the family had something other than their own clothes to bring away.
Neri inspected the back wall while the washers moved their tubs. The fallen blocks had come from an old storage room, not the washhouse itself. She pointed to a crack above the doorway and told the owner to keep the passage clear until it was shored.
“Can you do it?” the owner asked.
“My crew can. Not before we finish the bridge.”
“The bridge can wait,” Iven said.
Neri looked at him. “Can the stretcher crew wait?”
He glanced toward the lane. A pair of workers had reached the bridge with a stretcher between them. They were standing behind Dessa’s chalk line, waiting for someone to tell them it was safe to cross.
“No,” he said.
“Then we’ll ask the mason below whether he has a crew free. We’ll bring him the measurements.”
It was a better answer. Iven disliked that he had needed it, and liked that Neri had given it without making the people at the doorway wait for him to feel clever.
They returned to the bridge. Jem had fitted a temporary block beneath the shoe and kept the stretcher party on the near side. One of the bearers had made a sling for the injured person’s arm from a strip torn off his own shirt. The patient lay still under a blanket, watching the bridge as if it had personally offended her.
“This will be quick,” Neri told them.
“That’s what the last man said before my roof came down,” the patient replied.
“Then I won’t ask you to believe me. Watch the far post. If it moves past the chalk mark, we stop.”
The patient turned her head toward the post. Neri and Jem checked the temporary supports, then allowed the party onto the bridge. Iven walked beside the stretcher without touching it. The shoe held. The post stayed within its mark. Halfway across, the injured woman asked whether she could sit up.
“Not until we’re on the landing,” one bearer said.
“I’m not asking you. I’m asking the bridge.”
“The bridge hasn’t answered yet,” Iven said.
“Then it has better manners than most of the people I’ve met.”
They reached the far landing. The bearers continued toward Sera’s clinic, and the woman gave the bridge a final suspicious look over her shoulder.
Jem returned with the longer plate. It was a length of sound steel from the cooperative’s stock, drilled at one end and blank at the other. Neri marked the new holes against the solid backing rather than trusting the old ones. Iven held the plate in position while Jem drilled. The noise brought the mason back from the lower lane.
“You found more wall?” he called.
“We’re trying not to drop it on you,” Neri replied.
“That’s considerate. I’ve brought a helmet.”
He held it up. The dent in its crown suggested he had needed it before. Neri told him about the washhouse passage. He agreed to inspect it after delivering his buckets, and asked whether the family had a place to stay if the upper room had to be closed.
“Asa will know,” Iven said.
“Then I’ll ask her before I frighten them.”
The new plate went over the pocket and anchored into the sound sections on either side. Neri tightened the fasteners in sequence. Iven checked the shoe’s alignment while Jem removed the temporary block. The bridge settled under its own weight, then stopped.
They tested it with sandbags first. The far post moved a fraction and returned. Neri added another bag. The plate held without opening the chalk marks. Only then did she permit a handcart across, empty for its first trip and loaded with timber for the second.
The cart’s wheels rattled over the joints. Halfway across, Iven caught himself holding his breath. The cart reached the landing without a sound from the new plate.
“Can we increase the limit?” Dessa asked.
“To one loaded handcart with an attendant,” Neri said. “Not a crowd behind it. We’ll inspect after the evening shift.”
Iven touched the new bolt head. The metal was warm from his hands and the afternoon sun. He had repaired the bridge’s support, but the work was not his alone; Neri had found the pocket, Jem had cut the plate, and Dessa had kept the route clear. The important result was visible: people could cross without trusting a bolt driven into an empty space.
Brin arrived with a note from Tavin. Cage Seven’s gouged guide wheel had caught during the morning inspection. It had not failed, but the limit remained in place, and Tavin wanted a replacement before the next heavy transfer.
“Does he have a wheel?” Iven asked.
“There’s one at a freight yard. The yard says it’s reserved.”
“For whom?”
Brin unfolded the note. “It doesn’t say.”
Neri wiped her hands on a rag. “Then we’ll find out.”
The boy from the washhouse came up the lane with his dog. He held the animal under one arm now, though it was almost too big for him. The dog strained toward Iven, perhaps hoping for another dramatic escape. The boy offered him a wet, folded piece of cloth.
“Your coat was burning,” he said.
Iven looked down. A small scorch marked the hem. The boy had apparently put it out without Iven noticing.
“Thank you,” he said.
The boy nodded gravely and carried the dog away.
Neri watched them go. “You keep finding ways to damage that coat.”
“It keeps finding ways to stay attached.”
“Give it to me this evening. I’ll have someone patch the hem.”
“I can sew.”
“I’ve seen the evidence.”
He let her take the last word. He had a bridge to inspect after the evening shift, a wheel to find, and a coat that smelled like a washhouse fire. For a day that had begun with a falling bolt, it had acquired an unusual number of directions.
