At 0927 they were two blocks from Namsan Archive, parked in a records contractor van that Ryu had sourced overnight. White, dented rear bumper, logo of a records storage company that had gone out of business sixteen months ago. He'd pulled the logo from archived web images and had a print shop run it.
Caden wore a gray contractor vest. Two archive boxes in the back, one with actual files insideâNa-young had filled them from public records she'd pulled from the city database overnight, correct weight and aging, convincing from a glance.
Hana sat beside him in the van's cargo section, dressed like a researcher. Modest coat, document case, her archive visitor ID from two years ago that should still be in the system if nobody had flagged it.
She looked at the ID in her hand.
"If this has been flaggedâ"
"Na-young checked it this morning," Caden said. "It's clean."
"Na-young checked it three hours ago."
"Then we find out when we get to the desk."
She nodded. She'd put away most of her doubt since the planning session. What was left was just the right amountâthe kind that kept you sharp without making you freeze.
Vera had entered the alley side of the building nine minutes ago, on foot, with a maintenance bag and a transit worker's vest. She was in position.
"Earpieces off before we enter," Caden said. Min had stressed thisâjammer perimeter was real. "Radio silence inside."
"I know."
"If Dr. An asks about meâ"
"Colleague from the university archives office. You're returning a physical records pull." She'd rehearsed the cover story three times. "I won't volunteer anything."
They exited the van.
---
The Namsan Administrative Archive's public entrance was a glass door off the building's main facade, staffed by a single civilian security guard who checked IDs and logged visitor names. No weapons scanner. No biometrics. Researchers came in with laptop bags and document cases and no one checked the contents.
Hana's ID cleared without a pause.
Caden's maintenance passâa different identity than the Sector 5 card, Na-young had two blanksâcleared on the second scan. The guard frowned once at the delay. Caden shrugged and said the card was new and sometimes the chip took a moment. The guard handed it back.
They were in.
The main archive floor smelled like paper and humidity control. High ceilings. Rows of request terminals. Three researchers visible at the far tables. A records clerk at the collection window.
Dr. An Byeong-chul was at table six with four document binders stacked around him and reading glasses on the end of his nose, looking up a citation on a printout. Late fifties, reading glasses, the particular posture of someone who spent most of his professional hours not quite comfortable in any chair.
Hana walked toward him.
"Byeong-chul-ssi."
He looked up. His face went through surprise, then warmth.
"Baek-ssi! I didn't know you were coming." He started to stand.
She waved him down. "Sit, please. I'm just dropping a pull with my colleague. I didn't want to come in without saying hello."
He settled back, glancing at Caden with the brief assessment of a man who'd categorized him as non-relevant and moved on.
"I saw about the network situation in the news," Dr. An said, quietly. "That all looks very complicated."
"It is," Hana said. "Ongoing. I appreciate your concern."
"Of course." He looked back at her. "You look tired."
"I've had a busy few days."
"Well." He picked up his pencil. "If you need to look anything up while you're here, come find me. I know this floor better than anyone."
"I know you do," she said. "Take care of yourself."
She walked away toward the northeast corridor.
Caden followed with the cart.
---
The northeast corridor was thirty meters, academic storage on both sides, and ended at a service branch where a sign read BUILDING INFRASTRUCTURE - AUTHORIZED ACCESS ONLY.
Past the sign, in an unmarked alcove: the utility closet.
The closet held cleaning supplies and a freight elevator door that had no call button on its exterior. Just a card reader and a small keypad.
Na-young had given him a device the size of a thick wallet that connected to the card reader's bus port via a probe. He plugged it in and waited. Fifteen seconds.
The elevator door slid open.
He pushed the cart inside, turned it to face out, and pressed the single sub-basement button.
The car descended.
Seventeen seconds. Slower than a standard model. He made a mental note for the exit.
The door opened.
Antechamber. Three meters of plain corridor. Concrete walls, one overhead light, one security camera in the upper corner. At the end: a steel door. Through the reinforced window in its center, two guards visible at a desk inside the checkpoint.
He'd gotten two seconds of visual before the fire door alarm went off.
The sound came through the steel door as a muffled two-tone. Both guards stood up immediately. One reached for something mounted on the wallâ
The auto-lock engaged with a hydraulic thud that Caden felt in his feet.
He backed flat against the antechamber wall out of camera frame and breathed.
[Ground Sense] gave him what the camera could have. Both guards: toward the stairwell side. One had moved to the fire door. The other remained near the desk.
Seventy seconds of auto-lock. That was Na-young's estimate for an older electromagnetic system. Maybe sixty. Maybe ninety.
He counted.
At sixty-eight, the lock released with a second softer thud.
He heard the guard's footstepsâone set, moving from the fire door back toward the desk. The other set had gone through the fire door.
The second guard was in the stairwell. Looking for the source of the alarm.
Caden pushed [Ground Sense] through the steel door and found Vera's footstep signatureâfamiliar by now, the particular weight and distribution of someone with combat-calibrated movementâon the other side.
She'd been waiting on the stairwell side, inside the sub-basement level, during the alarm delay.
He tried the door.
It opened.
Inside the checkpoint, one guard at the desk looked up, hand going to his sidearm.
Vera came through the fire door behind the guard before he cleared the holster.
It was quick. The guard went down without a noise that would carry.
Caden crossed the checkpoint in four steps and tried the door to the medical bay.
It opened.
No one inside. Six empty examination bays, monitoring equipment on standby. The smell of antiseptic and filtered air.
The door to the cell block at the far end.
He tried it.
Locked.
Not card-reader locked. A different panel beside the doorâpalm reader, glowing red.
Section 9 biometric.
He pushed against it once with the heel of his hand. Solid. No give. No bypass port.
Through the cell block door's small reinforced window: a corridor of six doors. One of those doors had a light strip above it that was a different color than the others. Occupied indicator.
He pressed his palm to the glass.
Through it: movement. Someone had heard them.
A face appeared at the window.
Shin.
Left eye dark. Short-cropped hair. A scrape on her chin that hadn't been there before. She looked at him with the specific expression of someone who had already accepted that rescue wasn't coming and was now recalibrating.
She pointed at the palm reader. Then mouthed something.
He read it: *you don't have it.*
He pressed his palm flat to the door glass instead of answering.
She looked at him for two seconds. Then looked at the palm reader. Then back at him.
He had no way to tell her he'd come back. He had no way to tell her forty-one hours remained. He had no way to say anything except stand there like someone who'd gotten all the way to the table and found the wrong card.
She nodded once.
Not asking for anything. Just acknowledging.
Vera's hand landed on his shoulder. "Second guard will be back in under a minute."
He kept looking at Shin.
"Caden."
He stepped back.
They left the checkpoint the way they'd comeâfire door into the stairwell, up, through the alley exit, into the morning.

Nobody spoke on the walk back to the van.
Hana was already there, waiting. She'd left the archive normally, exchanged a few more words with Dr. An, taken the northeast corridor service entrance out after Caden had gone to the basement. She looked at their faces and said nothing.
Caden drove.
Four blocks from the archive, Min's voice came through the restored earpiece frequency.
"Status."
"We reached her," he said. "We couldn't open the cell." He let that sit for a moment. "The cell block has a Section 9 palm biometric. No bypass."
Min was quiet for three seconds.
"So we need a Section 9 biometric access holder."
"Yes."
"And we don't have one."
"We had one," he said. "We sent her running."
Longer silence.
"Park Hyun-ah," Min said.
"Yes."
"She went to ground in a residential building on Buseok-ro."
"Marcus had that address."
"Caden." Min's voice dropped. "You want to approach her."
"She's afraid. She doesn't know which way is safe. If we approach her rightâ"
"She's a Section 9 asset who we've been running surveillance on for less than twelve hours and whose motivations we don't fully understand."
"She ran from everyone when the spoof message hit. She didn't run to Epsilon. She ran to somewhere private and she's been sitting there for twenty-two hours." He kept his eyes on the road. "That's someone who's scared, not loyal."
"Or someone laying a trap."
"If Epsilon wanted to set a trap, they've had better opportunities."
More silence.
"I'll brief Kane," she said.
He drove.
Beside him, Hana was quiet. After two blocks she said, "She looked all right."
"Yes."
"She looked like herself."
He didn't answer. He was thinking about the look on Shin's face when she'd pointed at the palm reader. Not surprise. Not despair. Just the quick read of someone who'd already mapped their situation and was updating for new data.
Forty-one hours.
He'd gotten to the table and found the wrong card.
The question was whether Park Hyun-ah was the right card or a card that blew up the hand.
He drove through midmorning traffic and kept both possibilities open and didn't let himself lean toward either one yet.
