Chapter 5 - Halberd
Five years earlier, Forward Operating Base Halberd had smelled like diesel, dust, and burnt coffee.
I remembered that more clearly than the explosion.
Memories were cruel that way.
They preserved ordinary details while blurring catastrophe.
Nathan and I had spent seven months working inside a compartmented task force tracking stolen military encryption systems moving through Afghanistan.
At least, that was what we believed.
Malcolm Rusk had been our civilian technical adviser.
Thomas Vance coordinated intelligence support.
Back then, I trusted both men.
That trust had nearly buried me.
“Sarah.”
Vice Admiral Shaw's voice brought me back.
“Yes.”
“We need everything you remember about Halberd.”
“That's a long conversation.”
“We have time.”
I checked the horizon.
“For now.”
Daniel remained off my left wing.
His partner, Captain Maya Chen, flew right.
Their presence no longer felt like a cage.
It felt like armor.
I began.
“Three days before Halberd collapsed, Nathan discovered someone was copying our raw intelligence.”
“Who?”
“We never identified them.”
Nathan's voice interrupted.
“I did.”
My breath caught.
He continued.
“Rusk.”
I stared at the radio.
“You knew?”
“Not until the last night.”
Nathan explained that Aegis Meridian's predecessor had quietly embedded backdoor access inside specialized battlefield communications equipment.
The software collected operational data.
Not just enemy signals.
American signals.
Deployment patterns.
Response speeds.
Encryption behavior.
Rusk had discovered the commercial value of classified operational data long before the government understood what he was doing.
“He was selling it?” Shaw asked.
“Not directly,” Nathan said. “He was trading access for overseas investment and technology.”
The distinction barely mattered.
I remembered my final mission.
A helicopter.
A remote valley.
A supposed recovery operation.
Then gunfire.
Confusion.
Our communications failing.
Nathan ordering me onto a second aircraft.
The explosion afterward.
“We weren't attacked by insurgents,” I said slowly.
“No.”
“Who attacked us?”
Nathan hesitated.
“Contractors working through a security firm Rusk controlled.”
The truth hurt differently from grief.
Grief had been empty.
Betrayal had edges.
“Why didn't they kill me?”
“They tried.”
“But I survived.”
“Yes.”
After the crash, injured and disoriented, I had been recovered by an American search team led by Vance's people.
They told me everyone else was dead.
They told me intelligence indicated another assassination attempt was likely.
They gave me a choice.
Disappear or become a target.
So Sarah Mercer died.
Sarah Mitchell was born.
Ohio.
Flight instructor.
Quiet apartment.
Quiet life.
No family.
No past.
No questions.
“Vance wasn't saving me,” I whispered.
Nathan's silence confirmed it.
“He was containing you.”
I closed my eyes.
Five years stolen.
Not because I was being protected.
Because I was evidence.
Shaw spoke carefully.
“Why reveal Sarah now?”
Nathan answered.
“Because Rusk found her.”
“How?”
“I don't know.”
I did.
A memory surfaced.
Two months earlier, an elderly man had visited my flight school.
He introduced himself as Robert Kane.
He claimed he wanted refresher training.
During our second lesson, he looked at me while we practiced an emergency descent.
“You fly like military.”
I laughed it off.
Three weeks later, he disappeared.
I had thought nothing of it.
Until now.
“I was tested,” I said.
Nathan understood immediately.
“Explain.”
I told them.
Ortiz started searching.
Within a minute she responded.
“There is no pilot certificate under Robert Kane matching your description.”
Of course.
Shaw said, “Rusk verified your identity before setting today in motion.”
“But why use me?”
Nathan answered.
“Because Echo Actual still has access.”
I looked at the hidden radio.
My stomach dropped.
“My credentials?”
“They were never revoked.”
“That makes no sense.”
“It does if someone needed an authentication identity so compartmented that automated security systems would trust it without normal review.”
I stared at the green light.
I had thought activating the system gave me leverage.
Maybe that was exactly what Rusk wanted.
“Disconnect me from the network.”
Ortiz reacted.
“Sarah—”
“Now.”
I reached for the switch.
Nathan shouted.
“No!”
My hand stopped.
“Why?”
“Because once Echo Actual disconnects, the beacon switches modes.”
“What mode?”
Nobody answered immediately.
Then Nathan said:
“Autonomous.”
A new warning flashed across the display.
AUTHENTICATION ACCEPTED.
My blood ran cold.
Another line appeared.
PHASE TWO INITIALIZED.

I hadn't activated an old secure radio.
I had unknowingly supplied the missing key.
