His mouth tightened.

“Because courage sounds simple when the only person who pays for it is you.”

I looked away.

There was no good answer to that.

The old Carter property appeared around a bend.

The house had been demolished years earlier, but the barn remained.

So did a wide stump behind the foundation.

Cedar.

Marcus parked.

“Site security is aware of our location,” he said. “Local unit is ten minutes if needed.”

I nodded.

No one needed to say why.

Someone had stolen the box.

Someone had breached the communications facility.

Someone had left my childhood photograph inside.

Whoever had engineered today was not finished.

The stump was gray and hollowed at the center.

My father approached slowly.

“Tree used to be twice the height of the house.”

I walked around it.

Nothing.

Then I saw six shallow cuts in the wood.

Old.

Deliberate.

I knelt.

Band six.

I pressed against the sixth section between cuts.

The wood shifted.

Marcus crouched beside me.

“Compartment?”

“Looks like.”

We removed a rotted panel.

Inside was a narrow metal tube.

Not a wooden box.

My father let out a breath.

I pulled it free.

There was no lock.

Inside was a rolled sheet of paper protected by waxed cloth.

And a key.

I unfolded the page.

Thomas’s handwriting.

Rachel—

If you are reading this, then either I overestimated the problem or underestimated it. I hope it was the first.

Do not trust the box.

I looked at my father.

Marcus said nothing.

I continued.

The box contains records copied from my work. They are real, but incomplete by design. Anyone who finds them will believe they have the answer.

They do not.

The problem is not what the system transmits.

It is what the system remembers.

I stopped.

Marcus leaned closer.

Thomas had written a series of equipment designations beneath it.

Most were obsolete.

One was not.

ARCHIVE INTERFACE 47.

The cabinet.

The one opened today.

My mouth went dry.

At the bottom, Thomas had added:

If Cabinet 47 still exists, destroy nothing until you know who has been editing the archive.

Do not let them convince you this is about foreign intelligence.

It began here.

County side.

I heard a branch crack behind us.

Marcus moved first.

He pushed my father down behind the stump and turned toward the tree line.

“Show yourself.”

No response.

I moved to cover beside him.

Another crack.

Then a man stumbled through the brush with both hands raised.

Derek.

Marcus’s posture did not relax.

“What are you doing here?”

Derek looked at me.

“Mom’s gone.”

My father stood.

“What?”

“She left the house ten minutes after you did.”

“Vehicle?”

“No. Somebody picked her up.”

“Who?”

“I couldn’t see.”

“Why didn’t you call?”

“I did. You didn’t answer.”

I checked my phone.

No signal.

Derek looked at the paper in my hand.

“Is that Thomas’s?”

“Yes.”

He swallowed.

“Then we have another problem.”

“What?”

“The box wasn’t stolen today.”

I stared at him.

“What are you talking about?”

“My mom told me before she left.”

“When?”

“Right after you drove away.”

“What did she say?”

Derek took a breath.

“She gave the box away seventeen years ago.”

Part IV — What Thomas Left Behind

We got signal half a mile back toward the main road.

By then, Aunt Rebecca’s phone was off.

Sheriff Mercer issued a locate request.

Marcus contacted the communications site.

I called my mother.

Rebecca had said nothing before leaving.

No bag.

No coat.

She simply walked down the driveway at 3:42 p.m. and got into a silver sedan that stopped at the mailbox.

Todd had seen it through the kitchen window.

No plate.

No driver description.

Only one detail.

The passenger-side mirror had been wrapped with black tape.

Marcus listened to the information while driving.

“Could be damaged.”

“Could be rental.”

“Could be nothing.”

“Probably isn’t.”

My father stared through the windshield.

“Why would Rebecca go willingly?”

Derek answered from the back.

“Because she knows who called her.”

We looked at him.

He shook his head.

“She never admitted it. But she knows.”

“How do you know?” I asked.

“Because Mom is terrible at lying when she’s scared.”

“That’s not evidence.”

“No. But I’ve been a cop eighteen years.”

The irony landed between us.

Derek looked down.

“I know how that sounds.”

I said nothing.

He continued.

“When Mercer showed up, she wasn’t surprised somebody had used my card. She was surprised they’d found it in her car.”

“She used it.”

“That’s what she said.”

“You don’t believe her.”

“I believe she took it. I don’t believe she was the one who used it.”

Marcus glanced at him in the mirror.

“Why?”

“Because Mom can barely use the self-checkout at the grocery store.”

My father almost objected.

Then didn’t.

Derek leaned forward.

“And she told me she never drove through the gate. She said the card disappeared from her purse at the gas station.”

I turned.

“She told us she used it.”

“I know.”

“Why lie?”

“To keep me out of it.”

“No. If she wanted to keep you out, she’d say it was stolen.”

Derek went quiet.

Marcus said, “Unless she was protecting whoever used it.”

Exactly.

I called Sheriff Mercer.

He answered immediately.

“Anything?”

I explained Derek’s account.

Mercer was silent for a moment.

“General, there’s something you need to know about the card.”

“What?”

“It wasn’t merely used at the outer gate.”

I closed my eyes.

“Where else?”

“Maintenance access on the north perimeter.”

The drainage route.

Derek leaned forward.

Mercer continued.

“The first credential event occurred at 12:36. Second at 12:41.”

Five minutes.

Enough time for Rebecca’s card to be passed to someone waiting nearby.

Or cloned earlier.

“Video?”

“Outer camera captured her vehicle. North access camera had been physically obscured.”

“By whom?”

“Unknown.”

“Any prints?”

“Being processed.”

“Daniel. I need one thing from you.”

“Name it.”

“Find out everything Thomas Carter’s old county-side work touched. Permits. Utilities. Contractors. Deputies assigned to the route. Anything.”

“I’ll pull archives.”

“And locate Rebecca before anyone decides she’s no longer useful.”

“I’m on it.”

I ended the call.

Derek stared at the floor.

“She’s protecting someone.”

“Yes.”

“Who?”

“I don’t know.”

“But you have an idea.”

I looked at my father.

Walter had become very still.

“Dad.”

He did not answer.

“Who else knew Thomas?”

“Lots of people.”

“Who knew about his work?”

“I don’t know.”

“Who would Rebecca protect?”

He finally looked at me.

“Family.”

Derek shook his head.

“There isn’t anybody else.”

Walter’s eyes stayed on mine.

“Yes, there is.”

The sentence seemed to change the air inside the SUV.

“Who?” I asked.

My father took several seconds before answering.

“Thomas had a son.”

Derek whispered, “What?”

I thought I had misheard.

My father looked suddenly older.

“A boy. Christopher.”

“How old?”

“Born when Thomas was twenty-two.”

“Where is he?”

“I don’t know.”

“Who was the mother?”

“A woman named Elaine Porter. Thomas and Elaine were never married. They split when Christopher was a baby.”

“And no one told me?”
