Reading the Hum

The Hollow run was still chalked on the dispatch board, uninitialed, when Sarqon ducked under the first truss of Yadri Kessim's waystation, and the sound hit him before the old man did — a low, braided hum of a dozen engines working at once, bleeding down through the Seam's understructure like water finding every crack.

He'd walked past that hum a thousand times without really hearing it. Today he needed to.

"You're early," Yadri said, not looking up from the crate he was unpacking. He was a wide, stooped man with forearms like cable, gray hair cropped close against a skull that had taken more than its share of hits. "Or you're desperate. Man who shows up to my door before noon is usually one or the other."

"Call it early."

"Call it desperate." Yadri set a jar of something pickled on the shelf beside forty others exactly like it. "You want something, Nashaq. You've got the look. Chit-poor and time-poor both, and trying not to let it show in your shoulders."

Sarqon let that sit. There wasn't a version of this conversation where lying to Yadri Kessim worked, and he hadn't come here to practice. The old man read faces for a living the way other men read manifests, and he was better at it than most Compact auditors Sarqon had met, which was a low bar that Yadri cleared by a mile.

"I need to raise my Resonance," he said. "Fast, if there's a fast way."

"There isn't."

"Then the next fastest way."

Yadri finally looked at him — a long, assessing look, the kind he usually saved for cargo he suspected was hotter than advertised. "Why."

Because I died at the Dromat gate three days from now and the mechanism seized under me and I want to hear it happen before it happens instead of after. He couldn't say that, not the whole of it, not to a man who'd ask follow-up questions Sarqon had no honest answers for yet.

"Because the Hollow run through Dromat is tighter than I like," he said instead, which was true enough to hold a lie's shape without being one. "I want to hear a strained gate before I'm standing on it."

Yadri grunted, which from him counted as agreement. "That's not nothing. Most men want Resonance so they can brag about it at the dock. You want it so you can be somewhere else when the floor gives out." He wiped his hands on a rag that had given up being clean years ago. "Fine. Come listen to my mess."

"What's in the jars?"

"Don't ask questions you don't want answered before breakfast." Yadri set the last one down and didn't elaborate, which Sarqon decided to count as mercy.

The waystation ran four lift-engines under license — small, legal, grudgingly inspected — and Yadri kept them deliberately out of tune with each other, because, he said, a smuggler who could only read a quiet room had learned nothing worth knowing.

"Pick one," Yadri said, nodding at the engines. "Not the loudest. Pick the one that's wrong."

Sarqon closed his eyes and let the chorus come at him the way it always had — a wash of sound, no edges. He reached for the loudest strand in it, the one that pulsed hardest against his teeth, and pointed.

"That one. Second from the left."

"Wrong." Yadri didn't sound disappointed, exactly. He sounded like a man confirming a fact he already knew. "That one's loud because I feed it rich. Loud isn't strained. You're listening for volume because volume's easy. Strain's quieter than you think — it hides."

Sarqon tried again. This time he went the other way, chasing the thinnest thread in the hum, the one that seemed to flicker at the edge of hearing. He held it a second, lost it, reached for a second thread at the same moment to triangulate — and the two threads smeared together into noise, the way two conversations overheard at once become nothing at all.

"Lost it," he admitted.

"You tried to hold two," Yadri said. "Man who tries to listen to two engines straining at once ends up hearing neither. You've got one ear, Nashaq, whatever your chits tell you. Pick a strand. Hold only that one. Let the rest be noise."

"Is that one of yours, or does it actually finish somewhere?"

"Man who finishes his own sayings," Yadri said, not missing a beat, "has stopped learning anything new from them." He went back to his crate before Sarqon could decide whether that counted as an answer.

Third try. Sarqon stopped chasing volume and stopped trying to cover the whole chorus at once. He picked a single thread — not the loudest, not the faintest, just the one that felt, for half a second, slightly off its own rhythm — and he narrowed everything down to it the way a man narrows a lantern's beam by cupping his hands. The rest of the engines didn't disappear. They just stopped mattering.

There. A joint in the third engine's housing, flexing a half-beat late on every third cycle, like a knee that had taken one too many stairs.

"Third engine," he said. "Housing joint. It's dragging."

Yadri's eyebrows went up, a fraction. "That took you three tries instead of thirty. Most men need a season for that." He crossed to the third engine, laid two fingers against its casing, and nodded once, slow. "Dragging bearing. I've been meaning to get to it. You're not wrong, and you're not supposed to be right that fast."

[RESONANCE THRESHOLD REACHED: Isolate — Attentive Thread]

You can now hold a single mechanical signature inside a crowded chorus of noise at distance, filtering out ambient strain to track one source's rhythm specifically.

The words arrived the way they always did, somewhere behind his sternum rather than in front of his eyes, a fact rather than a voice. Sarqon had stopped being surprised by them. He'd started being grateful. Whatever kept the ledger on these things had a gift for naming the obvious like it was handing out medals — Attentive Thread, as if he'd been inattentive on purpose — but he wasn't about to complain to a notification that couldn't hear him.

"What was that," Yadri said. Not a question — he'd watched Sarqon's face go still and far-off for half a second, the way it always went when something landed that wasn't in the room.

"Nothing," Sarqon said. "Thinking."

Yadri let it go, the way he let most things go that he intended to remember later.

The Dromat Seam's checkpoint tower was visible from the edge of the waystation's lower deck, close enough that its own engine hum carried over the trusses even at this distance — the sound Sarqon had died inside three days from now and remembered dying inside like a bruise he could still press.

He walked out to the rail. Narrowed his attention the way he'd just learned to, the way that had taken him three tries and an old man's patience. He let the gate mechanism's hum come to him and picked a single thread out of it, the way he'd picked the dragging bearing — not the obvious strand, not the loudest. He went looking for wrong.

He found it.

Underneath the gate's working rhythm sat a second pulse, faint and regular, ticking against the main cycle like a second, smaller heartbeat out of time with the first. It didn't belong to opening. It didn't belong to closing. It ran constant, independent, grinding at something the gate's housing wasn't built to absorb — a stress harmonic with no business being there at all.

"Yadri." Sarqon didn't take his eyes off the tower. "Dromat Seam runs maintenance on what cycle?"

"Compact posts it every ten days. Why?"

"When was it last serviced?"

Yadri came to stand beside him, following his gaze to the checkpoint tower, and went quiet in a way that had nothing to do with proverbs.

"Six days back," he said slowly. "I know because I had a courier pass through it that morning, griping about the inspection delay." He looked at Sarqon sideways. "You're hearing something."

"A second pulse. Under the main cycle. It's not cosmetic strain — it's structural, and it's been running long enough to settle into its own rhythm." Sarqon kept listening, kept the thread held, because letting it go felt like closing his eyes on a road he hadn't finished crossing. "That gate shouldn't sound like that six days after service."

Yadri didn't finish his next sentence the way he usually didn't. He just stood there a long moment, listening to a hum he couldn't hear the way Sarqon could, weighing a thing he clearly didn't like the shape of.

"Man who finds a crack nobody ordered," he said finally, "is standing closer to it than—"

He didn't finish that one either. He didn't have to. Sarqon was already doing the math himself — the gate that killed him once wasn't failing because of anything he'd done to it. It had been failing on its own, quietly, under a maintenance record that said otherwise, since at least its last service.

Which meant whatever was wrong with the Dromat Seam had started before he ever touched it, and would still be wrong there long after this Turn, whichever way it ended.
