The former evidence-storage annex stood behind a row of abandoned industrial buildings, its windows covered with dusty metal shutters and its loading bay blocked by a rusted security gate.
The city had officially closed the facility five years earlier after transferring its evidence-management operations to a modern warehouse. Since then, the property had passed through several administrative arrangements, eventually becoming part of a private logistics lease.
From the street, it looked forgotten.
That was precisely what worried Daniel.
At 3:30 p.m., an independent investigative team arrived with the required authorization to inspect the premises. General Marcus remained at the command vehicle while the lead investigator reviewed the entry plan and confirmed that the property manager had been notified.
Daniel stood beside the vehicle, watching the building.
"Do you think the notebook is still inside?" he asked.
"I think someone wants us to believe it is," Marcus replied.
"Then why send us the photograph?"
"To control our attention. The photograph may be genuine, outdated, or deliberately staged. The threat may be intended to frighten you, draw you into a trap, or make us rush into an error."
Daniel glanced toward the building.
"Either way, we have to investigate."
"Yes. But we do it with authorization, independent witnesses, and a documented record of every item recovered."
The lead investigator approached.
"The initial inspection can proceed. The property manager has provided the access records, and the outer areas have been checked. We haven't identified anyone authorized to be inside the building today."
General Marcus nodded.
"Proceed according to the approved plan. If anything appears inconsistent with the inventory, document it before moving it."
The team entered.
Daniel remained with the command group, monitoring communications. For nearly fifteen minutes, nothing happened. The investigators photographed the loading bay, inspected the exterior doors, and began documenting the storage areas.
Then a voice came through the radio.
"We've located a restricted room at the rear of the building. The door was locked, and the property manager's key doesn't fit. We need to verify the authorization before attempting entry."
"Stand by," the lead investigator replied.
General Marcus turned toward the command vehicle's communications officer.
"Confirm the room's status with the property manager. No forced entry until the legal authority and safety conditions are established."
A minute later, Daniel noticed a white van moving slowly along the street beyond the gate.
It passed the entrance once.
Then it turned at the intersection and disappeared behind a row of warehouses.
Daniel watched it go.
"Did you see that?"
Marcus followed his gaze.
"The van?"
"It passed twice before we arrived. I saw it near the intersection earlier."
"Did you record the registration?"
"No."
Marcus signaled to the communications officer.
"Ask the team to document any vehicles observed near the property. Don't pursue anything without a lawful basis."
Before the officer could respond, a sharp metallic crash sounded from inside the annex.
Everyone outside turned toward the building.
A second later, the radio erupted with overlapping voices.
"We've got movement inside the rear corridor!"
"Hold your positions!"
"Possible unauthorized person!"
General Marcus raised his hand.
"Nobody rushes in. Get a clear report from the team leader."
Daniel felt every instinct telling him to move toward the building. He forced himself to remain beside the command vehicle.
A voice came over the radio.
"One person has exited through the rear door. We are attempting to establish their identity."
"Do not assume they are a suspect," Marcus ordered. "Maintain safe distances and follow the authorized procedures."
The communications officer relayed the instruction.
Seconds passed.
Then the lead investigator reported, "The individual has been detained for identification. No weapons observed. We have not confirmed whether they are connected to the investigation."
Daniel looked at the general.
"Someone knew we were coming."
"Possibly. We still need to establish who the individual is and why they were there."
The investigators continued documenting the scene. Inside the restricted room, they discovered several empty metal cabinets, damaged shelving, and a stack of old transfer forms.
The blue notebook was nowhere to be seen.
But one document caught Elena's attention when the team transmitted photographs to the secure office.
It was a transfer receipt dated six months earlier.
The receipt listed three boxes of archived case materials, one digital storage device, and a personal notebook recovered from Thomas Bell's property.
The receiving party was identified as Meridian Strategic Solutions.
The signature belonged to Nathaniel Shaw.
Daniel read the document twice.
"They moved the notebook out of the police system and into a private company's custody."
"That's what the receipt appears to show," Marcus replied. "We need the original document, the company's custody records, and evidence that the transfer was authorized or unauthorized."
The independent investigator soon returned with an update.
The person detained at the rear of the annex was a maintenance contractor who claimed he had been called to inspect a damaged electrical panel. His work order appeared legitimate, but the property manager had not received it.
The contractor insisted that he had entered through a side door that was already open.
Investigators documented his account and began checking the work order's origin.
Then Daniel's phone rang.
The number was unfamiliar.
He answered without speaking.
A man's voice came through, calm and almost amused.
"You shouldn't have come to the warehouse, Detective."
Daniel signaled to the communications officer that he was receiving a call.
"Who is this?"
"Someone who knows how this ends."
"Then tell me."
A short laugh.
"You think the general can protect you? You think a few recordings and some paperwork will bring down people who have spent years preparing for this?"
Daniel kept his voice steady.
"If you have evidence, provide it through the proper channels."
"That's what Thomas Bell believed."
The mention of Bell made Daniel's stomach tighten.
"What happened to him?"
"You have his notebook. Read it."
"We don't have the notebook."
"Not yet."
The call ended.
Daniel immediately documented the time and circumstances of the call and handed the relevant information to the investigative team. He did not attempt to call the number back or send a message that might compromise the investigation.
General Marcus listened to the account.
"Did the caller identify himself?"
"No."
"Did you recognize the voice?"
"No. It sounded deliberate, as though the caller wanted to disguise it."
"Then we'll preserve the call information and see what can be established."
Elena arrived with a tablet.
"General, we have something else from the transfer records. Meridian received several items from the old annex, but the company's current inventory doesn't list any of them."
"Can you identify the missing items?"
"One digital storage device, two case boxes, and the blue notebook."
Marcus looked toward the warehouse.
"Then we need to establish where Meridian moved them and who had custody."
Daniel glanced at the photograph of the notebook on his phone.
The warning had been intended to make him stop searching.
Instead, it had confirmed that someone was actively protecting the notebook's location.
"General," he said, "if the notebook contains evidence about Bell's death, the person who has it may be our best chance of finding out what happened."
"Agreed. But we won't let an unknown caller dictate our actions."
The team completed the initial inspection and secured the documents under the appropriate procedures. The contractor was released after his identity and account were documented, pending further verification of the suspicious work order.
As the investigators prepared to leave, a final notification arrived from the independent digital analyst.
The maintenance work order had been created using a temporary account linked to Meridian Strategic Solutions.
The account had been activated less than an hour before the team arrived.
Daniel stared at the screen.
Someone had arranged for a person to be inside the warehouse on the exact afternoon investigators came searching for the notebook.
Whether that person was a deliberate distraction or an unwitting participant remained unknown.
General Marcus read the report and gave a slow nod.
"We have enough to justify expanding the investigation into Meridian's role. But we still don't know who sent the threat, who has the notebook, or whether the caller has direct knowledge of Bell's death."
Daniel looked at the warehouse one final time.
The building had yielded documents, discrepancies, and another trail leading toward the same private company.
But the most important piece of evidence remained missing.
As they drove away, Daniel's phone vibrated once more.
This time, the message contained no photograph.
Only six words.
ASK MARCUS WHAT HAPPENED IN BLACKRIDGE.
Daniel read it aloud.
General Marcus went completely still.
For several seconds, he said nothing.
Then he looked out the window, his expression suddenly older than it had been that morning.
"Blackridge," Daniel repeated. "What happened there?"
Marcus slowly turned back toward him.
"An operation that was supposed to have ended twenty years ago."
"Was Adrian Mercer involved?"
The general did not answer immediately.
When he finally spoke, his voice was quiet.
"Yes."
He paused.
"And if someone is using Blackridge to threaten us, then the conspiracy surrounding Operation Clean Slate may be connected to the darkest failure of my career."
Daniel felt the weight of the words settle between them.
"Tell me what happened."
General Marcus looked toward the road ahead.
"I will."
His jaw tightened.
"But first, we need to establish whether the people who survived Blackridge are still alive."
