The call came in through Petty, which meant it was official, which meant it was small.
"District maintenance flagged a shadow anomaly in the west utility tunnels," the liaison said, folder out, apologetic already. "Minor. Probably nothing. The registry would like the response asset to, ah, respond."
"They want us to look at a basement."
"They want to be able to say the primordial response asset assessed it." Petty had learned to be honest with them, which was why they kept him. "It’s a formality. Bring one person."
Soren brought four and a mole.
Formalities were where people got sloppy, and sloppy was where the count found things.
◆◆◆◆
The tunnels ran under the old district in a grid nobody had updated in a long time.
Mona went first.
She was built for this. Low, blind-friendly, tinted lenses useless down here where there was no light to tint. She moved through the dark reading the ground with her whole body while the rest of them followed her nose.
"She’s faster than the map," Dani said, watching her go.
"She doesn’t trust the map. She trusts the dirt."
"The map’s surveyed."
"The map’s from before the district settled. Ask the dirt." Soren nodded at the mole. "The dirt’s current."
Dani filed that, which was the highest compliment Dani gave anything.
"She likes it down here," Maren said.
"She’s a mole."
"I’m saying she’s happy. Look at her."
Mona was, in fact, thrilled. She tunneled a little into a soft wall just because she could, backed out, and continued, radiating contentment.
"Don’t dig us a second entrance," Soren told her.
Mona did not agree to this.
◆◆◆◆
The anomaly was a cold spot two levels down.
Selah found it before the instruments did, one hand on the wall, frost refusing to form where it should.
"There," she said. "The shadow’s thin here. Something’s been feeding on the edges of the light."
"Feeding how much?"
"Not much. It’s small." She frowned at the wall. "The kind of thing that grows slow, a season at a time, if nobody comes. Somebody came."
Dani had her feeds up. "Reads as a splinter. Detached shadow, no core, no intent. It’s not a monster. It’s a leak."
"Then we plug the leak and go home," Soren said. "Maren."
Maren burned the cold spot out in thirty seconds, hearth-orange, thorough, and the shadow-thin patch of wall went warm and ordinary and dead.
Easy.
That was the part that bothered him.
◆◆◆◆
He stood in the cleared tunnel while the others packed up and ran the shape of the whole thing.
A leak. Small. Exactly big enough to justify a call to the response asset and exactly small enough to handle in an afternoon with no risk. A job sized to make them look competent and cost them nothing.
He’d seen jobs sized like this before.
All year, in fact. Every crisis of his first year had been exactly the right size. Big enough to matter. Small enough to survive. Sequenced, spaced, each one teaching one thing.
This one had taught tunnel work. Mole deployment. Cold-reading with Selah.
The unowned entry in his count turned over.
"Soren." Selah’s voice, from further down the tunnel. Flat, which meant she’d found something worse than the leak. "Come look at this."
◆◆◆◆
She’d gone twenty yards past the cold spot, off the assignment, because Selah did not stop at the edge of a task.
She was standing at a spot where the tunnel wall had been cut into once, long ago, and patched.
The patch had marks on it.
Soren put his light on them.
They were gouges. Parallel, deep, worn into the old stone in a groove, and at the bottom of each groove the surface was polished smooth and pale where something had rubbed the same track over and over.
He’d seen this exact wear before.
On oiled chains, under a festival, on links somebody had serviced into a groove that taught a god-piece where to file.
"Those are anchor marks," Selah said. "Something was chained here. For a long time."
"And maintained here."
"What?"
He crouched and touched the polished groove. Smooth. Recent-smooth. The kind of smooth that came from a hand coming back, on a schedule, with oil.
"The east yard chains had this," Soren said. "Exactly this. Same groove. Same polish."
"That’s the other side of the district."
"I know."
Dani came up behind them and read the wall over his shoulder. She went quiet. That was her tell for a data point that had just ruined a model.
"Two sites," she said. "Same maintenance signature. Different ends of the city."
"Whoever kept the east yard grave kept this one too."
"There’s no grave here. It’s an empty anchor."
"It’s an empty anchor with fresh polish." Soren stood. "Somebody’s been coming down here to maintain a chain that isn’t holding anything anymore."
Maren crouched by the marks and put her hand near them, not on them.
"Cold," she said. "The stone’s colder than the wall. Whatever was chained here liked the cold."
"Like the east yard."
"Colder than the east yard." Her ears were flat. "I don’t like this one. The east yard felt asleep. This feels moved out."
"Moved out where," Selah said.
Nobody had that one.
Soren looked at the empty anchor and made himself say the quiet part, at least to the count.
An empty grave was worse than a full one. A full grave, you knew where the thing was. An empty grave with fresh polish meant somebody had been keeping the ground ready for a tenant that had either left or hadn’t arrived, and either answer put a hole in his year that no shell and no Vasquez had ever explained.
◆◆◆◆
Nobody said the obvious thing on the walk out, so Soren said it in his own head where it belonged.
Two anchor points. One hand. A maintenance schedule that spanned a city and a year and served graves whose contents nobody had inventoried.
The east yard held a fragment. This one held nothing, or held nothing now, and the difference between those two facts was a door he wasn’t going to open in a utility tunnel with four bonds and a mole watching his face.
Mona stopped at the empty anchor on the way past.
She put her nose to the polished groove, held it there, and made a small unhappy sound, the one she made at the east yard seal.
Then she looked up the tunnel, further in, the direction they hadn’t gone.
"Augh," Mona said.
Aimed down. Aimed at something.
"There’s nothing that way," Dani said, checking. "Tunnel dead-ends in forty feet."
Mona did not agree, and did not move, and kept her nose pointed at the dead end until Maren picked her up.
Soren looked at the direction the mole had picked and filed it with the groove and the polish and the year of right-sized favors.
"We’re done here," he said. "Petty gets his formality. The registry gets its sentence."
"And the anchor marks?" Selah asked.
"Go in my report. The one nobody reads."
