The courier packet reached Solitude after Tamsin had finished charging a customer for work she had actually done.
She put the payment beside the pump’s completed job sheet, wiped the grit from her fingers and checked the relay marks. Dispatch on the thirty-fifth day. Two forwarding marks. Arrival on the thirty-seventh.
Someone at the lower camp had wrapped the boards properly.
Pell brought the clean paperweights without being asked twice.
“Coming home?”
“Something to check.”
“That wasn’t the question.”
“It’s the answer I’ve got.”
He set the weights where she pointed and watched her open the packet. Dimensions. A rubbing. Direction marked against the upper mount. The hidden area had been labeled hidden instead of filled with Felix’s hopes.
She appreciated that.
The morning’s pump stood in the district washhouse, where the owner had run it through the agreed ordinary cycle before signing the job sheet. It had moved the same water on the second run as on the first, without requiring a cultivator to look sternly at it.
Tamsin liked a completed job that stayed completed.
The owner had offered her another repair while she packed. She had booked a separate visit instead of turning one paid morning into everything the building might need. Her tools had come home in their own bag; her time had come home with them.
Now she laid out the incoming measurements in the space she kept for that work. Pell moved a drawing he’d made of the new bridge sections, pausing to put its corners under a book so the draught wouldn’t scatter it. He had drawn the gap too narrow. She left the correction for later.
The outer shape looked promising. So did the broad bolt pattern. Tamsin laid the rubbing beside the retained socket drawing and reached for the template she had made after measuring the garden shaft.
Three marks aligned.
The fourth did not.
She stopped.
Pell leaned forward until she held up one finger. He stayed on his side of the bench while she checked the measurement units, the orientation arrow and the fixed reference point.
Not reversed. Not a different cord standard. Felix and Lyra had repeated the accessible measurements.
The inner contact path met the wrong ring.
She fetched three loose washers and set them on the diagram. One marked the input. The next sat over the intended sharing path. The third rested where the candidate housing would send the load instead.
Pell followed the drawn line with one finger, keeping it away from the actual documents until she gave him a spare tracing.
“It goes round this one.”
“Yes. It would leave the inner ring taking the wrong share.”
He moved the third washer closer.
“That doesn’t move the metal inside the housing,” she said.
He put it back with an expression she had seen on several adults who had made the same proposal in more expensive words.
She checked the inner spacing against her template again before recording the failure. A wrong arrow could have caused this whole argument. The repeated reference point and the second measurement ruled that out.
She placed the template over the rubbing, lifting it slightly so Pell could see both.
“Here,” she said. “Our ring is inside this mark. That one feeds outward.”
“The holes fit.”
“Most of them. The load doesn’t.”
He studied the circles.
“Could we call it the right part and use the other holes?”
“Names are the cheapest material in a bad repair.”
“You say that about lots of things.”
“People keep offering them instead of fittings.”
She marked the matching points in one color and the incompatible contact in another. The shape had been built for a simpler distribution task. It could resemble the proper load-sharing coupler without doing its work.
The old removal inventory described the original component’s inner arrangement. The later storage reference used the same broad category, which had apparently survived into the recent shipment account. Somewhere along that chain, a cheaper substitute had acquired a description convenient enough to conceal the difference.
That did not tell her who changed it.
It told her not to install it under her house.
Pell fetched the second retained drawing when she asked. He read its label aloud, checking each letter before handing it over.
C-14B.
The final letter still mattered.
Tamsin compared the recorded contact spacing once more and wrote her conclusion on a fresh sheet: the measured housing was incompatible. Preserve its marks. Do not spend the return freight hauling it as the missing coupler.
A knock sounded at the workshop door.
The district progress officer arrived carrying the bridge schedule under one arm. He had crossed in the inspected basket, and his first question concerned the new material stack, not Felix’s travels.
His second concerned Felix’s travels.
“A component found?”
“A housing measured. Wrong inner arrangement.”
The hopeful expression left his face slowly enough to make her wish she had better news.
“Can we report the expedition on track for installation?”
“We can report they checked before hauling it.”
“People need a date. Crews need work sequenced.”
“Yes.”
“The funding review is easier with progress.”
She moved the template aside so he could see the mismatch.
“Then report the progress. They’ve located the wreck, recovered a loading amendment and measured the first candidate. It doesn’t fit. The second location still needs inspection.”
He looked down at the diagrams.
“Could the contact be altered?”
“Not into the load path we need by making another hole.”
“I had to ask.”
“You did.”
He sat on the stool Felix disliked and amended his draft. Tamsin let him finish without supplying a more encouraging adjective.
Then they went to the east abutment.
The public bridge remained a gap.
Paid work had changed everything around it. Sound supports had been prepared on both sides. Replacement span sections lay marked for their positions, protected from weather and stacked where their weight stayed inside the current cap. Across the gap, a crew on the academy side eased a new fitting into its cradle while the supervisor watched the hoist marks.
Pell stood behind the viewing line near the workshop approach. From there he could see the numbered sections without getting beneath a suspended load.
A worker on the Solitude side asked Tamsin about moving the next stack closer to the landing.
She checked its assigned position against the latest readings.
“Not all of it. First marked section only. The rest stays there.”
“Saves a lift if we bring both.”
“Uses the margin if the wind changes during the lift.”
He glanced across the gap, where the hanging fitting turned slightly against its guide.
“First only.”
The officer watched the lift begin, then wrote the actual completed stage on his schedule. It was less satisfying than crossing a finished bridge. It was more useful than pretending the finished bridge existed.
Tamsin checked the home-side support with the crew’s fabricator. He showed her the new pin seats, then the cover he had kept over the exposed work overnight. One edge had loosened in the rain; they fixed it before opening the next section.
A crew member brought over the next pin with the wrong number turned toward her. Tamsin made him rotate it before she approved the stage. Its other face carried the correct section mark.
“Thought you’d recognize it,” he said.
“I did. The next person won’t be me.”
He chalked the visible side and carried it back. Across the gap, the academy crew answered the raised signal with its own matching mark. The hoist moved a short distance and stopped exactly where the guide required.
Pell raised his hand behind the viewing line, copying the signal until the worker laughed and showed him which version meant nothing at all. The boy practiced that one too.
Tamsin waited for the fitting to settle before recording it. New wood and bright metal looked reassuring from a distance. Close up, the work consisted of people checking the right face, waiting for a signal and putting weight where the supports could take it.
Nobody needed to improvise a crossing to inspect a cover.
The basket line remained the authorized way across the gap. Cargo used its rated arrangement. Public foot traffic waited for structural completion, the correct coupler and a witnessed load inspection.
“Could this be the new bridge?” Pell asked when Tamsin came back behind the line.
He pointed at the nearest section.
“Part of it.”
“It looks small.”
“A bridge is lots of parts that have to agree.”
“People too?”
She looked at the two crews signaling across the gap.
“They make it harder.”
Pell watched the next signal with deep interest.
The officer’s final review included the work already paid, the next stage permitted and the stage waiting on the coupler. A proposed convenience fitting for the cottage had found its way onto the wrong materials line. Tamsin crossed it out and put it with the private work.
“It’s a small amount,” the officer said.
“Then it’ll be easy to put on the right bill.”
He corrected that too.
Back in the workshop, she checked the bypass record before writing the reply. The last witnessed inspection remained within range. Today’s observation marks agreed. The temporary arrangement still carried reduced load through the tested path.
The outer material limit remained the eighty-first day. No clean reading had made ten weeks begin again.
Felix’s return target was the seventieth. There was room between those numbers, but it belonged to weather, installation and things nobody had measured yet.
She wrote the current condition plainly.
Then she returned to the component warning.
The apparent housing’s broad category and bolt pattern were insufficient. Compare the inner contacts shown in the enclosed diagram. Use the surviving late-loading amendment to inspect the second location. Record the genuine model marks before assuming the next brass object was the answer.
She did not know whether the original coupler remained intact. She said so.
She also wrote that sending the measurements had been useful. They had avoided paying freight to bring home an expensive disappointment.
Pell watched her draw the second alignment arrow.
“Will Felix think you’re cross?”
“He’ll know the part is wrong.”
“That’s not the question either.”
She looked at him.
He had inherited an inconvenient ear for incomplete answers.
Tamsin added a final line saying the kettle worked and no one had asked it for permission to use the kitchen.
“Better?”
Pell considered.
“Maybe say we still have his room.”
“He knows.”
“He might like it written.”
She wrote that too, then folded the page before the boy could appoint himself chief correspondent.
The courier took the reply for the next outward relay. Tamsin checked the destination against the latest forwarding stop and paid the proper charge. It would not reach the field shelter today. Weather and the ordinary route would decide how quickly it completed the journey.
After the packet left, she entered her completed work hours and put the pump payment in its proper place. A local customer’s return fitting waited on the bench beside her own tool roll. She had promised it for tomorrow, and Felix’s travels had not repaired it by correspondence.
Pell finished his observation note from the safe mark. He brought it to her before making any conclusion about the machinery.
She checked it, thanked him and set the rebuilt kettle going.
It clicked off at the right point.
The house had warm water, work for the morning and a room whose absent occupant would be angry at the wrong component for several entirely understandable reasons.
Pell brought his bridge drawing back after supper. This time he widened the gap, then complained that the new sections no longer reached across it. Tamsin gave him another sheet instead of letting him make the missing distance disappear beneath a much larger painted cloud.
Tamsin drank her tea beside the true socket template. The red-marked mismatch remained on the bench, where neither a good wish nor an encouraging report could move it into alignment.
