The colleague's facility was a ground-floor space in a converted logistics building off the coastal road, the kind of industrial building that accumulated functions as its original one became obsolete. The bottom floor had been a cold-storage facility once, which meant thick walls and a concrete floor that held temperature well and a heavy door with commercial seals.
Dr. Kim had a key.
Inside: two workstations, a third monitor for reference, a climate-controlled equipment cabinet with drives arranged in a system that Dr. Kim understood and Na-young assessed in thirty seconds.
"Good setup," Na-young said.
"She's particular," Dr. Kim said. "So am I." She plugged in the drives. "We'll run dual analysis streams. You take the waveform comparisonâI'll handle the metadata chain."
Na-young was already pulling up a chair.
Kane set his phone on the table's edge and started work of a different kind. Calls, quiet, ticking through a list of contacts in the way of someone running a logistics operation from memory.
Caden went to the window.
The coastal road was visible from hereâtrucks, a couple of early-morning fishery vehicles, the particular light of a harbor city before the working day started. Nothing that looked like a vehicle pacing or a person anchored.
He pressed his palm to the wall.
Concrete, excellent for [Ground Sense]. Nobody in the adjacent spaces. Nobody in the corridor. The building felt empty except for them.
He stood there for a while.

At 0930, Min called from Seoul.
"The maritime freeze is being challenged," she said. "Section 9's legal team filed a counter-motion at 0915. Emergency stay request based on jurisdictional groundsâthey're arguing that a Hunt Internal Affairs proceeding has no authority over Section 9 infrastructure."
"Does the argument hold."
"In a standard proceeding, probably not. In an emergency stay at 0915 in the morning with a judge who's being lobbied by people who outrank Magistrate Ohâ" Min paused. "It creates delay. The freeze isn't lifted. But it's in question."
"How long before Oh rules on the counter-motion."
"She's asked for submissions by 1400. She rules by end of business." Min's voice had the particular flatness of someone delivering bad news without edging it. "If she upholds the freeze, we're still on the original timeline. If she suspends itâSection 9 starts moving immediately."
End of business was roughly 1800. They had twenty-six hours on the authorization window. If the stay was granted, those twenty-six hours became three.
"Where's Yeo," he said.
"In her office running the inquiry. She's been on it since last night. She knows about the counter-motion." A pause. "She says to tell you she's not planning to fold."
He didn't doubt that. What he doubted was whether Yeo's intent was the variable that mattered.
"The forensic authentication," he said. "How much does the case change if we get it in time."
"Na-young's assessment is that authenticated evidence of recording tampering, combined with the registry fragment and Park's testimony, gets us past a threshold where Yeo can't be blocked on procedure alone." Min said it carefully. "With the authentication, the counter-motion looks like obstruction, not jurisdiction. Without itâ"
"It's Yeo's word against Chae's filing."
"Yes."
He looked at the window.
"We need every hour Dr. Kim has," he said. "Give me regular updates."
He hung up and went back inside to tell Kane about the counter-motion.
---
Kane received the information in the way he received most information: standing very still for four seconds and then speaking.
"Section 9 has three attorneys capable of drafting an emergency jurisdictional stay," he said. "At least one of them is Chae Yun-seo's standing counselâshe keeps them on retainer, which means they were ready for this move before the freeze was filed." He looked at Caden. "This was anticipated."
"Yes."
"Which means she also anticipated the authentication."
"Yes."
"She has a counter to it."
"She has a counter prepared for everything," Caden said. "The question is whether she has a counter for Na-young and Dr. Kim specifically."
Kane was quiet.
"Kim resigned rather than authenticate a tampered recording," Caden said. "She knows what she's looking for. She built her entire independent practice around documentation that can't be challengedâbecause she knows exactly how it gets challenged." He leaned against the wall. "Chae has a counter for the concept of forensic analysis. She doesn't have a counter for Kim's methodology."
"You hope."
"I calculate." He kept his voice level. "It's a different calculation than yesterday's, but it's still a calculation."
Kane didn't look convinced. But he also didn't argue.
---
By noon, Dr. Kim had produced an initial analysis of the first session file.
She printed it and placed it on the table and both she and Na-young looked at it in the specific silence of people who'd been staring at evidence for three hours and were seeing it for the first time on paper.
"The modification is clear," Dr. Kim said. "The timestamp discrepancy alone is admissible in most jurisdictions as evidence of tampering. But that's the minimum." She tapped the printout. "I'm finding four distinct edit points in session one. The seventeen-minute estimate Na-young made from the backup metadata was conservative. It's closer to twenty-three minutes of removed content."
"That's four separate cuts," Na-young said.
"Yes. Each one corresponds to a shift in the interrogation's direction." Dr. Kim looked at Caden. "What they've done is sophisticated. They didn't remove Shin's statementsâthey removed the interrogators' questions before those statements. Without the questions, her answers read differently."
He thought about that.
"They left her saying the right things," he said. "But stripped out what they were responding to."
"Correct. So she sounds cooperative, forthcoming, supplying information voluntarily. When in fact she was answering specific leading questions that shaped every response." Dr. Kim picked up her pen. "Session threeâthe nine-second insertionâthat's even cleaner. The inserted audio is from a different session entirely. A different day, by the background noise profile. Someone extracted a sentence from another recording and placed it here."
"Can you prove the original source."
"If I have access to the other session files, yes. The question is whether you have them."
Na-young pulled up her file list. Scrolled.
"I have six session files on the drive," she said. "Three are labeled. Three aren't."
"Open the unlabeled ones," Caden said.
Na-young opened them.
Three additional recordings. Not debriefing sessionsâthese were what the editing had removed. Interrogation audio, context and all: the questions before the answers, the pressure, the specific pauses and re-attempts that made the "cooperative" readings into something else entirely.
Dr. Kim listened to thirty seconds of the first unlabeled file.
She looked at Na-young.
"They kept the source files," Na-young said. "In the backup partition. They edited the presentation files but didn't delete the originals."
"They assumed the backup was secure," Caden said.
"They assumed," Na-young agreed, with the particular satisfaction of someone who'd spent seventeen hours maintaining that assumption and then broken it.
Dr. Kim set her pen down. "Give me six more hours. I'll have full documentation that any court in the country will take seriously." She looked at Caden. "Assuming we're not interrupted again."
"We won't be," Caden said.
He hoped that was true.
---
The afternoon passed in the particular way of waiting during something importantâtime simultaneously too slow and too fast, every update either not enough or too much to sit with.
Kane managed the legal counterplay from the table, on calls or composing messages for most of the afternoon. At 1612, Magistrate Oh's ruling came through: freeze order upheld. The jurisdictional challenge was noted and deferred to standard proceedings, which would take weeks. For now, the freeze stood.
Caden read the update and sat very still for a moment.
One variable resolved.
He was aware of how many remained.
Vera had been quiet for most of the day. She'd taken a position near the door after the morning's move, watching the facility's approach from the narrow window, checking the building's perimeter at intervals that were regular enough to be useful and irregular enough not to be predictable. She moved through it with the ease of someone who'd spent decades making herself hard to surprise.
At some point after 1700, she sat down on the low concrete ledge that ran along the interior wall and stretched her legs out.
"Sit down," she said, without looking at him.
"I'm functional."
"You've been standing for four hours. Sit down."
He sat down on the ledge.
His cheekbone was a steady specific ache that he'd been managing through the day by not touching it. [Pain Resistance] had spent four years being the thing he could rely on when his body decided to inform him of its condition. Without it, his body was informing him at full volume.
"How bad," Vera said.
"Manageable."
"Caden."
"Two things. The cheekbone from the dock exchange. And my right knee has apparently been taking more impact than I knew." He looked at the knee in question. "The knee has opinions."
"The knee has had opinions since before I met you." She looked at him sidelong. "You bought [Enhanced Speed] at the wrong price."
"Yes."
"You know that."
"Yes."
She was quiet for a moment.
"I've lost skills I shouldn't have lost," she said. "Everyone does. The system is what it isârandom is random, even when you've calculated against it." She stretched her arms overhead, cracking something in her shoulder. "The thing you have to watch is whether you start making impulsive kills because you're behind. Trying to recover faster than the math allows."
"I know."
"Do you." She looked at him. "Because the kill in the alley this morning was not a calculated play. It was recoverable without the kill."
He could argue with that. He had an argument ready, had been constructing it since the alley. The man had a weapon, the situation could have escalated, the expected value of taking the skill while the option was in front of him wasâ
He didn't make the argument.
"You're right," he said.
She turned her head slightly, as if the agreement surprised her.
"I'm telling you because the game ahead gets harder, not easier," she said. "If you're making uncalculated plays nowâ"
"I said you're right."
She looked at him. There was something in the look that was different from assessmentâharder to define, harder to file. He'd spent enough time across tables reading people to know when a look meant something outside the context it was framed in.
He looked away first.
Outside, the coastal road was quieting downâlate afternoon, the early trucks done, the fishing fleet out. The building around them was still.
"You should sleep," Vera said. "Kim needs another six hours. There's nothing useful you can do for six hours."
"I can watch the door."
"I'll watch the door."
"You need sleep too."
"Less than you think." She stretched her legs out again. "I don't sleep much. Haven't since Incheon."
He'd heard her mention Incheon twice now. The safe houses Chae Yun-seo had burned fifteen years ago. He'd never asked her to fill in what was around it.
He looked at her profile.
"How many people," he said.
She was quiet for long enough that he thought she wouldn't answer.
"Eleven," she said. "Seven in the first house. Four in the second. Third was emptyâI'd already moved." She kept her eyes forward. "Seven of the eleven I knew. Three I'd only met once. One I'd never metâwe were supposed to that week."
He sat with that.
"I looked for her," Vera said. "Two years. The third house was where she'd been living. I thought maybe she'd gotten out before it burned." A pause. "She hadn't."
He had nothing useful to offer for that. He didn't try.
"Get some sleep," she said. Her voice had the same register it always didâno variance, nothing added or subtracted. But she'd said twelve words to him she hadn't said before. "I'll have you up in three hours."
He leaned his back against the concrete wall and closed his eyes.
He didn't expect to sleep.
He did.
---
She woke him at 2043, which was slightly more than three hours, and the facility was still running, and Dr. Kim was still working, and nothing had gone wrong in the interval.
He sat up with his cheekbone reminding him of its existence and his knee seconding the motion.
The coastal road outside the window was dark. Harborside dark, with the particular quality of industrial waterfront at nightâdistant machinery, the smell of fuel and cold water, lights that were functional rather than decorative.
He looked at Vera.
She handed him a cup of coffee from a portable setup in the corner that hadn't been there before.
"Where did that come from," he said.
"I went to the corner shop." She sat back down on the ledge. "It's been there. I checked the approach first."
He drank.
The coffee was too hot and too strong and tasted like a corner shop in Busan, which was to say it tasted like salt air and industrial district and getting back to work.
"Thank you," he said.
She shrugged.
He held the cup with both hands and watched the window.
Six hours until Dr. Kim's analysis would be ready. Twenty-two hours on the freeze order. Eighteen hours until their operational window closed.
He'd been dealt a bad hand at the alley this morning.
The new hand wasn't better. But it was different, and different was something to work with.
He watched the dark harbor and waited for morning.
