Priya examined the system.
“There's an elevator call at 1:10. It traveled from the sixth floor to the basement.”
“Who called it?”
“Unknown. The elevator control system doesn't record individual identities.”
Adrian looked at Marcus.
“The basement.”
They moved quickly through the stairwell, followed by two investigators.
The basement housed vehicle storage, maintenance equipment, and an old records archive that had not been used regularly in years.
The fluorescent lights flickered above rows of parked vehicles.
At the far end stood a door marked ARCHIVE B.
It was slightly open.
Adrian approached cautiously.
“Laura?”
No answer.
He pushed the door open.
Inside, metal shelving filled the room. Cardboard boxes were stacked against the walls, each labeled with a year and a department code.
A single desk lamp illuminated a table near the back.
On the table lay a white envelope.
Adrian approached it without touching it.
His name was written across the front.
DETECTIVE ADRIAN CROSS.
Marcus looked toward the doorway.
“Could be a trap.”
“Probably.”
Adrian photographed the envelope and its surroundings before asking an investigator to document it.
Inside was a handwritten note.
You are looking in the wrong place.
Beneath it was a second line.
Daniel did not die because of the audit.
Adrian read the message twice.
Marcus frowned.
“What does that mean?”
“It means someone wants us to question the motive.”
“The audit was the only reason anyone would have wanted him silenced.”
“Maybe. But the person who wrote this wants us to believe there's another reason.”
Adrian examined the handwriting.
It was neat, deliberate, and unfamiliar.
There was no signature.
No date.
No explanation of where Laura had gone.
He placed the note back into the evidence sleeve.
Then he noticed something beneath the table.
A small black flash drive had been taped to the underside.
The investigator photographed it before removing it.
Adrian examined the label.
DF-03.
Daniel Foster's initials.
And the number three.
“That's not a random label,” Marcus said.
“No.”
“Could it be the missing drive?”
“Possibly. But we don't connect it to anything until the digital team verifies it.”
Adrian looked around the archive.
There were no signs of a struggle.
No broken furniture.
No overturned boxes.
Nothing suggested that Laura had been forced into the room.
Yet she had left a message that seemed designed specifically for him.
He took out his phone and called the department's front desk.
“This is Detective Cross. I need to speak with Sergeant Nolan.”
A moment later, Nolan answered.
“Sergeant Nolan.”
“Where is Laura Bennett?”
“She went home.”
“Her vehicle is still in the parking lot.”
“She may have taken a ride.”
“Who authorized her to leave her shift?”
Nolan paused.
“I'm not aware that anyone needed to authorize it.”
“Did you see her leave?”
“No.”
“Did anyone see her leave?”
“I couldn't say.”
Adrian's voice became colder.
“Sergeant, an employee who may be a witness in an active investigation has disappeared from the building. Her access credentials were used after she was supposedly gone. I need you to tell me exactly what you know.”
Nolan exhaled.
“I saw her speaking with someone.”
“Who?”
“I couldn't identify him.”
“Describe him.”
“Dark jacket. Tall. Maybe in his forties.”
“Uniform?”
“No.”
“Did you see his face?”
“Not clearly.”
“Where did they go?”
Nolan hesitated.
“Toward the administrative elevators.”
Adrian looked at Marcus.
“Did you report this?”
“No.”
“Why?”
“I didn't think it was important.”
Adrian ended the call.
Marcus stared at him.
“He's lying.”
“Or he's afraid.”
“Does that distinction matter?”
“It matters when we decide what to do next.”
Adrian turned to the investigator.
“Preserve the envelope, the note, and the flash drive. Have the digital team image the device using the approved forensic process. No one opens the files on a standard workstation.”
The investigator nodded.
Adrian looked at the empty shelves.
“Find out who has access to Archive B.”
Marcus checked his phone.
“Already doing it.”
A message arrived.
Marcus read it and frowned.
“What?”
“Archive B was scheduled to be cleared two weeks ago.”
“By whom?”
“An administrative disposal request signed by Deputy Chief Vance.”
Adrian looked at the note again.
Daniel did not die because of the audit.
Someone had tried to direct his attention away from the financial investigation.
Someone had planted a flash drive connected to Daniel.
And someone had removed Laura Bennett from the building without leaving a clear record.
The question was whether those actions came from one person.
Or whether two rival factions inside the department were using Adrian to expose each other.
He turned toward the door.
“Marcus, I want a discreet search for Laura. Hospitals, transit cameras, nearby businesses. No department-wide alert.”
“Understood.”
“And contact the state witness protection coordinator.”
Marcus's eyebrows lifted.
“You think she's a protected witness?”
“I think someone considered her important enough to remove her from the building.”
Adrian glanced down at the note.
“And I think she left us something because she knew she might not get another chance.”
Chapter 6: The Flash Drive
At 2:03 a.m., the digital forensics laboratory confirmed that the flash drive contained three encrypted files.
The first was a spreadsheet.
The second was a scanned document.
The third was an audio recording.
Adrian stood behind Priya Shah as she opened the spreadsheet in an isolated forensic environment.
Rows of transactions filled the screen.
Dates.
Contract numbers.
Invoice references.
Payment authorizations.
The document appeared to track payments made by the city to Sentinel Municipal Solutions.
At first, the numbers seemed ordinary.
Then Priya sorted the entries by recipient.
Several payments had been routed through subcontractors that did not appear to have legitimate business operations.
One company listed a residential address.
Another shared a phone number with a business that had been dissolved two years earlier.
A third had received nearly four million dollars for equipment that had never been delivered.
Adrian leaned closer.
“Who approved these payments?”
Priya expanded the relevant column.
“Most were approved through the public safety procurement office. But the final authorization codes belong to the department's executive administration.”
“Vance?”
“His office's credentials appear on several entries.”
Marcus folded his arms.
“That's enough to establish a financial connection.”
“It's enough to justify further investigation,” Adrian replied. “Not enough to establish that Vance personally knew what was happening.”
Priya opened the scanned document.
It was a formal internal memorandum dated eight months earlier.
The subject line read:
DISCREPANCY REVIEW — EVIDENCE RECORD 24-771.
The memorandum described a missing digital storage device and an inconsistency between a witness statement and the final investigative report.
At the bottom, a sentence had been highlighted.
The original recording must not be released until the discrepancy has been resolved.
The document carried the signature of Daniel Foster.
Adrian stared at it.
“Why would Daniel sign a memo saying the recording shouldn't be released?”
“Maybe he was instructed to delay it,” Marcus suggested.
“Maybe. But look at the date.”
The memorandum had been signed two days before Daniel's death.
And the file's metadata indicated that the document had been scanned several weeks after his death.
Someone had taken an original document and digitized it later.
That alone was not necessarily suspicious.
But the digital signature did not match the version preserved in the department's archive.
Priya compared the two files.
“The signatures look similar, but the metadata is different. This version was created on a workstation assigned to the deputy chief's office.”
“Can you determine whether the signature image was copied?” Adrian asked.
“I'm running a comparison now.”
The result appeared a few seconds later.
Priya turned toward him.
“The signature image is identical to one found on another document.”
“Which document?”
“A routine equipment authorization signed three years earlier.”
Marcus swore under his breath.
“Someone copied Daniel's signature.”
“Possibly,” Adrian said. “We still need the original paper document and a qualified forensic examination. But the evidence strongly suggests this version was assembled after the fact.”
He sat down.
The implications were serious.
If someone had fabricated a memorandum bearing Daniel's signature, the goal might have been to make it appear that Daniel himself had ordered the evidence withheld.
That would redirect suspicion away from whoever altered the final report.
It would also create a convenient explanation for why the original recording had disappeared.
Adrian opened the third file.
The audio began with a faint hum, followed by the sound of a chair moving across a hard floor.
A man spoke.
“It's already been changed.”
Another voice replied.
“Then change it back.”
“I can't. The signed version is in the system.”
“Then remove the signed version.”
A pause.
“That would trigger an audit.”
“Only if the audit sees it.”
Adrian raised a hand.
Priya stopped the recording.
“Play that again.”
She replayed the last sentence.
Only if the audit sees it.
Marcus looked at Adrian.
“That sounds like Vance.”
“Maybe.”
“You recognize the voice?”
“I've heard him speak at briefings. But this recording is too short to make a reliable identification.”
Priya adjusted the audio.
A second section became audible.
“Foster knows about the original.”
The first voice replied, “He knows enough to be dangerous.”
“What do we do about him?”
Silence.
Then a third voice entered the conversation.
“Nothing happens to Foster until the review is finished.”
Adrian leaned forward.
“Stop.”
Priya froze the audio.
“Third voice,” he said. “Can you isolate it?”
“I can try.”
“Do that.”
She separated the sound into several frequency ranges and replayed the passage.
The third voice was quieter, but clearer.
“Nothing happens to Foster until the review is finished.”
Adrian listened carefully.
Something about the voice was familiar.
Not Vance.
Not Lieutenant Harris.
Someone else.
Someone whose authority came from outside the department.
He asked Priya to play the next section.
A chair scraped.
Then the first voice spoke again.
“The detective has already copied the file.”
The second voice replied, “Then we have a bigger problem than the audit.”
The third voice answered.
“No. We have a problem with the people who think the department belongs to them.”
The recording ended.
Marcus stared at the screen.
“Whoever that is, he sounds like he's trying to stop them.”
“Or trying to make us think he is.”
Adrian stood and walked to the far side of the laboratory.
