The rain had stopped.
But the city had not dried.
Water clung to the courthouse steps and reflected the pale morning sky as Seo Hae-in arrived before eight.
She noticed the black sedan immediately.
Same model.
Same tinted windows.
Different plate.
Hae-in slowed for half a second.
Then kept walking.
She had learned not to stare at things that wanted to be noticed.
Inside her office, Detective Kang was already waiting.
He had two coffees on the desk.
She looked at them.
"You came early."
"So did you."
"I always come early."
"I know."
She picked up the coffee.
"Thank you."
Kang smiled faintly.
"You're welcome."
That was all.
No unnecessary conversation.
Hae-in placed her bag down and looked at the board.
The case had changed since yesterday.
The second man's disappearance had added another layer to the investigation, but something about it bothered her.
Not the escape.
The timing.
She turned toward Kang.
"Show me the original visitor records."
"I already did."
"The original ones."
He understood.
Five minutes later, a scanned document appeared on the monitor.
The visitor registry from the night before the murder.
Father.
Lawyer.
Medical representative.
Three names.
Three signatures.
Hae-in stared at the page.
"Zoom in."
Kang did.
She studied the signatures.
The father's handwriting was shaky.
The lawyer's was precise.
The medical representative's signature was almost illegible.
"Something's wrong."
Kang leaned closer.
"What?"
"Look at the dates."
He frowned.
All three visitors had signed in on the same day.
But the times were different.
19:42.
20:06.
20:31.
Hae-in pointed at the last signature.
"Who was this?"
"The medical representative."
"Why was a medical representative visiting him?"
"According to the file, routine medication review."
"Was he actually there?"
Kang checked another record.
"There's no medical appointment."
Hae-in looked at him.
"Then why is his signature here?"
Kang didn't answer.
He began searching.
Ten minutes later, he stopped.
"There's no employee with this name."
Hae-in's eyes narrowed.
"Search former employees."
Nothing.
"Contractors."
Nothing.
"Medical staff."
Nothing.
Kang slowly leaned back.
"He doesn't exist."
Hae-in looked at the signature again.
"No."
She shook her head.
"Someone used his name."
"Whose name?"
She pointed toward the file.
"The person who signed this."
Kang frowned.
"How do we find someone who doesn't exist?"
Hae-in closed the document.
"We find out who the name belonged to before someone erased it."
The detention center archive was colder than the rest of the building.
Metal shelves stretched toward the ceiling.
Old records filled cardboard boxes.
Hae-in disliked archives.
Too many things were forgotten there.
And forgotten things were easy to manipulate.
The warden unlocked a cabinet.
"These are personnel records from the last ten years."
"Good."
Kang pulled out the first box.
They worked in silence.
Names.
Dates.
Transfers.
Resignations.
Retirements.
Nothing.
Then Hae-in found a thin folder at the bottom of the third box.
It had no label.
She opened it.
Inside was a single personnel form.
The name at the top had been crossed out.
But underneath it...
was another name.
Kang leaned over her shoulder.
His expression changed.
"That's the same name."
Hae-in nodded.
The medical representative.
Except this record was dated eight years earlier.
Position:
Correctional Medical Liaison.
Status:
Terminated.
Reason:
Unauthorized access to restricted patient records.
Kang looked at her.
"Why would a terminated employee be visiting a prisoner eight years later?"
"He wasn't."
She turned the page.
There was another document.
A termination notice.
Then a transfer request.
Then—
Nothing.
No death certificate.
No new employment.
No address.
The person had simply disappeared from the records.
Kang whispered,
"Someone cleaned him out."
Hae-in didn't answer.
She was looking at the final line.
Last known assignment: Cell Block C.
The same cell block.
The same building.
The same place where the mysterious maintenance inspection had occurred.
Her phone vibrated.
A message.
Unknown number.
One sentence.
You are looking in the wrong year.
Hae-in stared at it.
Kang noticed.
"What does it say?"
She showed him.
His face tightened.
"How do they know where we are?"
Hae-in looked around the archive.
Rows of boxes.
Locked cabinets.
A security camera above the door.
Then she looked at the phone again.
"They don't."
"What?"
"They don't know where we are."
She put the phone away.
"They knew where we were going."
By noon, the old personnel file had been transferred to the police evidence room.
Hae-in sat across from Kang.
Three names were written on the board.
The father.
The missing second man.
The former medical liaison.
They were connected.
But not in the way she expected.
Kang placed another photograph on the table.
"We found this in the old archive."
It showed a group of detention center employees standing outside the facility.
Hae-in studied it.
There were twelve people.
Doctors.
Guards.
Administrators.
Maintenance workers.
She counted them.
Then stopped.
"Who is that?"
Kang followed her finger.
A man standing at the edge of the photograph.
Half his face hidden behind another employee.
"That's him."
The medical liaison.
Hae-in looked closer.
There was something else.
The photograph had been taken eight years ago.
The man was standing beside the detention center director.
But behind them, barely visible through the glass doors...
was a young woman.
Hae-in's breathing changed.
She took the photograph closer.
"Do you recognize her?"
Kang shook his head.
"No."
Hae-in did.
Not immediately.
But enough.
She had seen that face before.
In the case file.
A photograph attached to a witness statement.
A woman who had claimed she knew nothing about the father's disappearance.
A witness who had later withdrawn her statement.
Hae-in placed the photograph beside the witness file.
Same face.
Same eyes.
Same small scar beneath the left eyebrow.
Kang stared.
"That's impossible."
"No."
Hae-in looked at the date on the photograph.
Eight years ago.
Then at the witness statement.
Three months ago.
The woman hadn't simply known the father.
She had been inside the detention center years before the murder.
And someone had made sure nobody remembered.
Hae-in stood.
"Find her."
Kang grabbed his jacket.
"Where?"
Hae-in looked at the photograph one last time.
"Everywhere."
Her phone vibrated again.
Another unknown message.
This time, there were only four words.
You finally found her.
Hae-in stared at the screen.
Then slowly looked toward the window.
Across the street, a woman stood beneath the awning of a closed café.
Black coat.
Dark umbrella.
Watching the courthouse.
Watching her.
Hae-in moved toward the window.
The woman turned.
Their eyes met.
For one second, neither moved.
Then the woman lowered her umbrella.
And Hae-in saw the scar beneath her left eyebrow.
The woman smiled.
Not warmly.
Not fearfully.
As if she had been waiting for this exact moment.
Then she walked away.
Hae-in reached for her coat.
Kang looked at her.
"What happened?"
She was already heading for the door.
"We found her."
"Who?"
Hae-in didn't slow down.
"The woman who never told us the truth."
And for the first time since the case began—
she wasn't chasing a clue.
The clue was running from her.
