Chapter 408: Beneath the Returning Water

The return washed over the walk beneath the steps.

Ren had one foot on the first step and the replacement under his arm. Wenna was climbing above him. Orrin was still near the span, gathering the line, with Hadde coming behind him, lamp raised.

Ren carried the bundle to the first turn, set it against the wall clear of the steps, and went back down.

Water pulled across Orrin’s legs toward the lower openings. He tried to bring his trailing foot forward and had to set it down again. The loose end of his line snapped taut in the current.

Ren reached into the short stretch between the span and the steps. He bent the flow past Orrin, leaving a quieter strip along the walking line. More water pressed into it from farther up the course. Ren braced his footing with Earth in the plain stone beneath him and caught Orrin’s forearm.

"Leave the loose end. Come here."

He hauled Orrin onto the steps. The man gathered the line against his chest and climbed clear.

"Hadde!"

She kept one hand on the wall, feeling for the edge of the walk with her foot. Water reached her thighs where the stone dipped. Ren held the strip open until she reached him, then pulled her onto the bottom step.

Above them, Wenna slipped.

A surge struck the wall below the first turn and washed across her footing. She fell sideways, her outstretched forearm hitting the stone edge. Ren let go of Hadde as Orrin caught her elbow. He took the steps in a stride and seized Wenna’s coat below the shoulders before she slid farther.

"My arm."

He got an arm beneath her back and lifted her clear. She clutched the injured forearm against her chest.

The lamp below them swung as water struck it. Its hook came free, and the light dropped into the return.

Ren kept his grip on Wenna. He still had water pressing across the walking line, and Hadde had not cleared the lower steps.

The fallen light passed beneath the span. Hadde raised her lamp over Orrin’s shoulder.

"To the landing," she said.

Ren carried Wenna up. Orrin collected the replacement at the turn, and Hadde followed, lighting their footing. Only when her boots reached the dry shelf did Ren release the diversion. Water closed over the strip below.

— • —

Wenna sat against the landing wall. Orrin put the replacement beside her, still wrapped, while Hadde set down her lamp. At the shelf’s uphill end, the upper crossing rejoined the main stair above the older closure. Water still covered the low span below them.

The forearm beneath Wenna’s wet sleeve was swelling. She kept her other hand under it while Hadde looked.

"Could be broken. Orrin, take her up to Tamsin. She needs a healer."

"I can ease some of this," Ren said.

Wenna nodded without looking up.

He rested his hand over her sleeve, keeping its weight off the injury. He had used Life on Bolt’s torn tissue; here he followed the hurt around the bone, easing the gathering blood and heat. Wenna’s breathing slowed. Ren stopped there. He could not tell how the bone lay, and he left it alone.

"Less," she said. Her grip on the sleeve loosened, then tightened as she tried to shift her arm.

"Keep it there," Hadde said. "Orrin’s nearly ready."

He had split a narrow strip from the replacement’s packing board. Hadde unbuckled her lamp’s carrying strap, and he used it with a length of line to secure Wenna’s splinted arm against her coat. Ren held the arm steady while he worked.

Hadde called up the stair. The nursery hand answered, then came toward the landing with a light.

"Tell Tamsin what’s happened. Orrin’s bringing her up."

Wenna drew out her slate with her good hand.

"Beyond the junction," she said. "The return rose there first. Before the slot nearer the steps. Both readings are on here."

She held it out. The wet edge slipped in her fingers, and Hadde caught it in both hands. Wenna kept her thumb pressed against the corner until Hadde had a firm grip. Then she let go, and Orrin helped her stand.

Hadde put the slate inside her coat. The hand went ahead with the light; Orrin followed, supporting Wenna on her uninjured side.

Along the landing’s other wall, a narrow maintenance ledge continued above the flooded walk toward the far end of the course. Hadde lifted her lamp and pointed along it.

"That reaches the back of the coupling. We can get at the seat from above."

"Is there room to work?"

"A bay beside it. We’ll look. If you can keep the seat clear, I can fit the replacement. If you can’t, we leave it wrapped and come back along this ledge."

Ren picked up the bundle. Hadde went first with the lamp.

— • —

The ledge narrowed enough that Ren turned sideways to carry the bundle past a projecting rib. Below, the approach to the first pair of mouths had vanished under moving water. He could follow the current beneath his feet, but lost it where the gallery bent.

They reached a wider working bay behind the junction. Hadde set her lamp on a dry shelf and knelt beside the coupling. Ren put the replacement within her reach.

From here he could see the edge hidden from the approach. The coupling met its seat along a short strip. Beside it, a finger-wide gap opened beneath the worn face. Water pulsed through whenever the current crossed the junction.

Hadde rested her palm on the fitting, then on the stone beyond the gap.

"The working’s still in the piece," she said. "It isn’t passing the change through this contact properly."

Ren touched the near edge. He could follow the response within the coupling and feel where it faltered at the seat. Beyond that, he could not separate it from the rest of the course.

"That’s holding the chambers?"

"It’s disrupting their discharge. We’ve had late fills and water held through the ebb. This connection should keep those responses together." She pressed her palm against the far contact again. "Wenna’s readings will tell us which ones emptied into the return first."

She leaned over the bay and pointed below it.

"There’s your receiving chamber. Mouth here, outlet at the bottom. Check all three."

Ren followed the water through the mouth. The chamber’s level was below the old working mark on its wall. Through the lower opening, he could read the outlet drawing water away; the passage turned beyond it, out of his reach.

"The outlet’s running. There’s room."

"Take enough in to clear the seat. The rest can keep going along the approach toward the span." Hadde pointed to the mark. "Call before it reaches that. If you can’t keep the seat clear without filling the chamber, I stop. Leave the regulator’s working to me."

Ren drew part of the crossing flow into the mouth. The chamber rose slowly. Water still passed along the approach, but the wash over the coupling’s seat thinned and fell away.

Hadde watched it through another surge.

"Keep that."

She fitted her iron hook into the old coupling’s lifting eye and took a short bar from her coat. The bar gave her room to lift the seated edge. She worked it free a little at a time while Ren watched the mouth and the chamber below.

The coupling shifted. Water struck through the open contact and curled toward the recess where Hadde was working.

Ren caught the change and bent more of it into the receiving mouth. The level began rising faster. At the bottom, the outlet continued drawing, but less was leaving than entering.

"The chamber’s rising," he said. "Still below your mark."

Hadde pulled the coupling clear. She set it face up on the bay’s dry stone, then held a hand over the empty recess to follow the changed working.

"Keep reading the outlet."

Ren unwrapped the replacement beside her, leaving the cloth and its binding cord tucked beneath the packing board. She checked the new face against the exposed seat. Its dressed edges followed the shape of the recess; the formed passage through its middle would meet the passage in the old stone.

"You’ll have to lower it against the water," she said. "I’ll guide the edge. When it meets, hold it there while I join it."

He crouched beside her and took the fitting in both hands.

The receiving mouth was accepting less. Its chamber had filled enough to resist the incoming share, just as the nearer chamber had behind the landward branch. Here the outlet could not clear the extra water he had sent in after Hadde lifted the coupling.

The level had not reached her mark. Ren reduced the share entering the mouth and let more pass along the approach toward the span. The stronger current tried to curl into the empty seat. He kept its edge turned past the recess.

"I’ve reduced it," he said. "The outlet can’t clear that much."

"Seat?"

"Still clear."

Hadde looked at the chamber mark, then put her hands against the fitting’s edges.

"Down."

Ren lowered it. Water pushed against the underside, turning one corner toward the recess. He held the piece level while Hadde guided that corner past the lip. Her fingers moved away, then returned to the upper edge.

"A little toward me."

He shifted it. Stone touched stone. Hadde ran a finger along the meeting edge, checked the far side, and pressed down with her palm.

"There. Hold it."

The weight was easy. Keeping the fitting motionless while the water struck beneath it took his attention. He braced his knee on the plain ledge stone and watched the receiving chamber through the gap beside Hadde’s arm. Its level had slowed below the mark. Most of the return now passed the bay, held off the seat by the narrow turn he maintained in the flow.

Hadde worked at the lower contact first. Ren felt the cultivated pattern in the replacement meet the old course. He could follow the nearest join taking up the response, but she continued farther along it than he could read.

She shifted her palm to the other edge. Water struck under the fitting again, lifting against Ren’s hands. He kept it seated. Below them, the receiving level crept upward once more.

"Still rising," he said.

"How close?"

"Below the mark. Less room than before."

Hadde kept her hand at the far contact. Ren held the fitting and the turn in the current, watching for the level to reach the line.

Then the outlet began drawing more strongly.

He checked the mouth. He had not changed its share. The level steadied, then fell beneath its wet trace on the chamber wall.

"The outlet’s taking more."

"The far side’s answering," Hadde said. She moved her hand back across the join. "Ease the water off. A little first."

Ren loosened the turn beside the seat. Water passed the new fitting and continued along the approach. It no longer curled into the recess. He let more of his diversion go, watching the chamber and its outlet together.

The level kept falling.

He withdrew the last of his Water working. Hadde stayed at the contact through another pulse of the return, then told him to release the fitting.

Ren lifted his hands. The coupling remained seated. A thin stream passed along its outer edge without washing over the join. Below the bay, the return was running lower, exposing part of the approach they had left underwater.

Hadde watched through several more pulses before sitting back.

"It’s joined and answering. We’ll need the next change to check the cycle."

She turned the old coupling in the lamplight. The hollow on its seating face ended in a worn, uneven strip. Ren rested his palm on the unbroken stone beside it. The Water working still ran within the piece, organized beyond the depth he could follow. The failed contact had not erased it.

"We’ll have this examined," Hadde said.

She marked the seating side, folded the coupling into the replacement’s wrapping, and secured it with the saved cord.

A light appeared along the ledge. The nursery hand called from the bend before coming into the bay.

"Wenna’s above. Tamsin’s sent for the healer. The outside marker’s turning."

Hadde checked the new seat once more, then lifted the wrapped coupling. Ren gathered the empty packing board and took her lamp from the shelf.

The hand led them back along the dry ledge, his fresh light reaching the next turn.
