The reject bin stood by the melt pit, a waist-high iron box where the yard threw anything that had failed a test and was not worth the trouble of logging. Tavin went to it in the middle of the morning, rummaged with one arm to the elbow, and came back to the bench with a valve.
It was a cheap one: a cast body about the size of two fists, a bore through the middle, a threaded stem, flanges at either end with the bolt holes filled with old rust. Somebody had painted it green once. Most of the paint had gone.
He set it down in front of her.
“Drill,” he said.
She looked at it, then at him. In three years he had never asked her to listen to anything. He had let her, on the days she did it without asking. He had tagged what she wrote. He had called it stress. But he had never put a piece of metal in front of her and told her to listen.
“With the cup?” she said. He had taken the brass earpiece from her in the shed and had not given it back.
He reached into his apron pocket and set it on the bench beside the valve, the wire coiled neatly around it.
“Ten minutes,” he said. “I’m counting.”
She uncoiled the wire. She tucked the end behind her left ear, against the graft, and pressed the brass cup to the valve’s body, just above the bore. Then she closed her eyes.
The yard was loud that morning. A wagon was unloading at the gate. Arlo had the cutting torch going on a frame by the fence, a hiss and a roar, and somewhere beyond the wall a crop-dome pump was changing over with a long grinding wheeze. All of it came through the bench and the floor and the soles of her boots, a muddle of noise.
She waited. She let the noise be noise. Under it, slowly, she found the valve.
It began as a plain hum, the sound most cast metal made, a kind of grey drone with no particular note in it. She breathed and pressed the cup a little harder. Under the hum, very faint, there was a thread: a thin high note, so high it was almost not a note at all, more like a pressure. It had a wobble in it. The wobble was regular, a pulse, as though the note were being plucked at the same point over and over.
She moved the cup slowly along the body, following the bore. The thread came with her. At the first turn of the bore, where the internal passage bent, it was steady. At the second turn, steady. At the third turn, the wobble widened and caught, and the note stuttered.
She held the cup there. Stutter. And under the stutter, not in the bore but beneath it, a second thing, a faint grinding, like grit between teeth.
“A stutter at the third turn of the bore,” she said, with her eyes still closed. “Not the bore. The weld under it. There’s a repair weld under the bore at the third turn, and it didn’t fuse.”
“Write it before you say it,” Tavin said.
She opened her eyes. He was standing at the end of the bench with his arms folded, his wrist clock in his hand, watching her.
“I said it.”
“I heard you. Write it before you say it.” He nodded at her apron pocket, where the notebook was. “If you say it first and you’re wrong, you’ll remember it the way you said it. If you write it first and you’re wrong, you’ll have the page.”
She took the cup off the valve. She took out the notebook, opened it to a clean page, and wrote: the time, which she read off his wrist clock upside down; green cast valve, reject bin; stutter at third bore turn; repair weld under bore, unfused. She wrote it in the left column, under today. She looked at the third column, empty, and left it empty.
Then she said it again, aloud, from the page. “Stutter at the third bore turn. Repair weld under the bore. Not fused.”
Tavin took the valve. He carried it to the vise at the end of the bench, clamped it with the bore running crosswise, and took the hacksaw from its hook. He set the blade at the third turn. He never asked her to show him where. He had heard her, and he had seen her write it, and he set the blade exactly where the third turn was.
He began to saw.
It took a long time. The cast body was thick and the blade was old, and Tavin sawed slowly, steadily, his whole shoulder in each stroke, pausing every twenty strokes to blow the filings away. Mara stood beside the vise and watched. She kept quiet. She found she was holding her hands together in front of her, very tightly, and made herself let go.
The blade went through the outer wall and into the bore. Tavin sawed on. The sound changed as the blade went deeper: a bright rasp in the clean metal, then, suddenly, a duller, grittier sound, and the blade jumped a little in the cut.
He stopped. He pulled the saw out and set it down and opened the vise.
The valve fell into two halves in his hands. He turned the cut faces up to the light.
There, under the bore at the third turn, was a seam. A line of different metal, a little darker than the casting around it, where someone long ago had filled a crack with a repair weld. Along most of its length it had fused cleanly into the casting. But at the center, for a length about as long as her thumbnail, a thin dark gap ran between the weld and the cast metal, a hairline, a place where the two had never become one.
Exactly where her note had put it.
Tavin looked at it for a long time. He turned the half-valve in his fingers, tilting it in the light so the gap caught and lost the glare. He put his thumbnail into the gap. It went in.
He was silent. The torch hissed by the fence. The wagon at the gate creaked as the last crate came off.
Then he said, “Keep doing that,” and set the two halves of the valve down on the bench, side by side, cut faces up, and went back to the hacksaw hook to hang the saw.
That was all.
Mara stood looking at the two halves. Something moved in her chest, a small warm pressure, and she distrusted it. It felt like pleasure. It felt like being right in front of someone who had always called the thing she did stress. It felt good in a way that made her want to do it again, immediately, to pick up the next valve from the reject bin and press the cup to it and find the next seam and see his face go still again.
The graft prickled behind her ear. It was a small sensation, a faint itch along the edge of the bone, the feeling that came before a long listen, when the graft was warming to a sound and wanted more.
She took the cup off its wire and set it on the bench. She coiled the wire around it, the way Tavin had, neatly. She stopped.
She did not start a second listen.
The pleasure was still there. She let it sit and gave it nothing. She thought of the shed and the old bell and the line of pain from her ear to her temple, and the forty-one minutes she had lost without noticing, and she thought that the pleasure and the bell were not so far apart. The graft did not care which one it played her. It only wanted to be listening.
She picked up the two halves of the valve and carried them to the bins. There was a box by the property cage, marked in chalk TESTED, where the yard put pieces that had been cut and checked and could be sold for what they were rather than what they looked like. She set the halves in it, cut faces up, so whoever bought them would see the seam.
When she came back Tavin was at the bench, writing on the slate.
“What’s next?” she said.
He kept his back to her. “Widow on Coil Stair. Second floor, number six. Heat pump. She brought it in for a look three days ago and I put her off. She’ll be bringing it up the lane in four days, on the cart, and I said we’d do the job then.” He wrote something on the slate and stepped back. “She’s been waiting.”
Mara remembered the pump. The widow had wheeled it in three days ago on a handcart, a squat steel box with a motor on one end and a pressure manifold on the other, and wheeled it home again when Tavin put her off. Its job card still hung on the hook by the office door, in Tavin’s handwriting: Ines Toller. Pump. Low output. Collar? Mara had glanced at the pump while it sat in the gateway and heard nothing in particular, a tired old motor and a manifold that wanted cleaning.
“I’ll do it,” she said.
“You’ll do it with me.” He turned. His face was the usual face, closed and plain. “Before you touch the collar, read the plate on the pump. All of it. Rated pressure, rated flow, the lot. And then ask her what pipes it feeds. What kind, how old.”
“The collar’s on the pump.”
“The pump’s on the pipes,” Tavin said. “Read the plate.”
“I’ll read the plate,” she said.
He looked at her a moment longer, as though weighing whether she meant it. Then he nodded and went back to the slate.
She looked at the job card on its hook by the door, fluttering a little in the draft from the gate. Four days. A widow on Coil Stair who had already waited three, a motor and a manifold and a collar that might or might not be the fault. And a plate on the side of the pump, small, stamped, that she had not yet read, because she had not thought to.
She would read it. She had said she would. But she could feel, already, in the small warm place where the pleasure from the valve was still sitting, how much she would rather put her hand on the collar first and listen.
