The junction hub on forty-three smelled like every other junction hub Cole had ever worked: ozone and hot plastic, the particular sharpness that came off transformers running closer to their ceiling than anyone wanted to admit.
He shifted the parts crate higher on his shoulder and took the long way through.
The long route kept him clear of the main stairwell, and he had four minutes of margin before his return-time window closed.
Someone was crouched at the access panel near the trunk line.
Cole slowed.
Not stopping stopping would read wrong to anyone watching just letting his pace drop to match a man checking his own mental list.
Making sure he’d grabbed everything he needed before the climb back up.
The kind of hesitation that happened a dozen times a shift, unremarkable as breathing.
The tech at the panel had a tester in one hand, leads clipped to a segment of the stairwell feed, and she was working it methodically: no wasted motion, tracing the draw back one junction at a time.
Her coveralls said Mechanical.
Her movements precise, deliberate, no fumbling with the clips told him she knew exactly what she was looking for.
Cole stopped at a tool rack ten feet down the corridor.
Set the crate on the deck.
Made a show of checking the manifest clipped to the side, even though he’d already checked it twice.
She didn’t look up.
The tester beeped once, a short confirming tone, and she made a note on a pad balanced on her knee.
Moved the leads two segments down the line.
Reset.
The tester beeped again, longer this time, and she paused.
Wrote something else.
Her hand was steady.
Cole couldn’t see her face from this angle, just the line of her shoulders and the methodical certainty in the way she repositioned the leads.
She was isolating something.
A spike, maybe.
A draw that didn’t match the manifest for this section.
A draw that shouldn’t be there.
His draw.
Cole picked up the crate.
Turned toward the stairs.
Three steps, unhurried, just a tech finishing his errand and headed home.
The kind of movement that didn’t register because it was exactly what you’d expect to see in a junction hub at the tail end of a shift.
She glanced up.
Their eyes never met.
She was looking past him, or maybe through him, her gaze still halfway inside the problem while the real world ran on without her.
Just an electrician passing with a parts crate.
Nothing worth a second thought.
She went back to her tester.
The beep came again, and Cole heard her exhale soft, controlled, the sound of someone finding the thread they’d been hunting.
Cole kept walking.
Made the stairs.
Didn’t look back.
His boots rang on the metal treads, each step measured to match the rhythm he’d learned to keep without thinking about it the pace that said routine and unremarkable and nobody worth watching.
The crate wasn’t heavy but he felt its weight anyway, a specific pressure against his collarbone that gave his hands something to do besides shake.
The exact segment his cast had run through.
The exact place where Faculty B had pulled power it shouldn’t have needed, left a signature invisible to standard logs but bright as fire to someone who knew how to read the current.
Not the display itself he’d killed that feed the second it had started to resolve, pulled it dark before anyone but Pell had gotten a clean look at it.
But the power draw.
The signature left behind when Faculty B did whatever it did to a screen, the faint off-pattern spike that standard maintenance logs would miss entirely but a tester and enough patience would flag in seconds.
Corliss was looking for a behavioral pattern.
Shift overlaps.
Faces in the wrong place at the wrong time.
This woman whoever she was was looking for the actual signature.
Cole made level fifty-six with two minutes to spare.
Logged the parts return.
Handed the manifest to the depot clerk, who initialed it without looking up and waved him off with the kind of automatic dismissal that meant the paperwork was clean.
Standard end-of-errand procedure.
Nothing flagged.
Nothing worth remembering.
He walked home the long way.
Took the residential bypass instead of the main stairwell, added fifteen minutes to the route.
Let himself think through the shape of what he’d just seen without the pressure of needing his face to stay neutral in a crowd.
Out here the foot traffic was lighter mostly people heading home after shift, too tired to notice anyone else.
She’d been good.
Really good.
The kind of good that came from years of working a problem until it surrendered, not from following a checklist someone else had written.
Mechanical, the coveralls had said, which meant she had access to the infrastructure from the bottom up.
Power routing.
Load balancing.
Every junction and transformer between Down Deep and Up Top.
The skill he’d seen wasn’t just competence.
It was the patience of someone who’d spent years reading electricity as a language, tracing anomalies through miles of conduit until the pattern resolved.
She’d find the spike.
She’d cross-reference the timestamp.
And when she found no fault report, no scheduled repair, no reason for that screen to spike and die in eight seconds, she’d have questions that wouldn’t settle.
Questions, in a silo this size, eventually found their way upward to the people who decided whether they mattered.
Cole reached his door.
Unlocked it.
Stepped inside and set his bag down by the table the same spot he always set it because routine was what kept a person invisible, and invisible was the only safe place left.
He had no idea what her name was.
No idea if she was chasing the spike on orders or because she’d stumbled across it and refused to let it go.
No idea if her trace would end with him or dead-end at a board with no serial number and a power log that proved nothing but coincidence.
But he knew the rhythm of her work.
The patience.
What he did know: she’d gotten closer than Corliss had.
Closer than anyone had.
And she didn’t even know she was hunting him.
Cole sat down at the table.
Let his hands rest flat against the surface, palms down, fingers spread.
The tremor he’d been holding off since the junction hub worked its way through his wrists and settled the body finally catching up with what the head already knew.
Two threads now, closing from different angles.
Judicial from above, hunting for the face that kept showing up in the wrong shift logs.
Mechanical from below, hunting for the signature that had no business existing in the power draw.
He’d spent three days convinced his only problem was Corliss narrowing a list.
He’d been wrong.
The silo was bigger than one deputy’s investigation.
A hundred forty-four levels.
Ten thousand people.
More junctions than any one person could count, more wire than anyone could map in a lifetime.
And somewhere in all that infrastructure there were techs like the woman he’d just seen methodical, patient, good at their jobs who pulled threads simply because the threads were there and the numbers refused to add up.
Cole had assumed Corliss was the threat.
The deputy with her interview logs and her pattern-matching, tightening the circle one name at a time.
But Corliss was hunting behavior.
This woman was hunting physics the burn of electricity through wire, the trace of power where none should have flowed.
And physics left marks you couldn’t talk your way out of.
She probably had a name.
A shift rotation.
A supervisor who signed her work orders and trusted her to chase down anomalies without asking too many questions first.
A history.
Cole didn’t have any of it.
Just her face.
The way she’d moved her hands.
The patience in the way she’d repositioned those leads.
What he had was her face, locked now in memory alongside every other detail that mattered, and the cold certainty that if she kept tracing that spike she’d trace it all the way back to a screen on a landing four levels up, and the only person standing close enough to touch it when it died.
He pulled his hands off the table.
Flexed his fingers once, twice.
The tremor was gone, or buried deep enough that it didn’t matter which.
Tomorrow he’d work his shift.
Fix the boards that needed fixing.
Answer the questions he was asked and no others.
Keep his routes clean and his face steady and his name off every list he could manage.
And he’d count the people hunting him.
Two now.
Maybe more tomorrow.
The silo was full of people who were good at their jobs.
Sooner or later, one of them would be good enough.
