He had been terminated after an internal investigation.

I turned to my husband.

“You lied?”

Aaron closed his eyes.

“Yes.”

He admitted he had approved vendor paperwork he knew was questionable. His supervisor had pressured him, using subtle threats about his new position, our rising rent, and the fact that we were expecting Caleb.

Then Marisol began investigating.

Aaron cooperated for two weeks.

Then someone left photographs under our apartment door.

Pictures of me.

Pregnant.

Walking.

Driving.

Living my life while someone watched.

Aaron panicked and destroyed the envelope.

I stood, shaking.

“You found photos of your pregnant wife being followed, and you said nothing?”

“I thought I was protecting you.”

“You don’t get to use that word yet.”

His face crumpled.

“I know.”

Part 6: File 417

Aaron said he stopped cooperating after the photos. Two months later, his company blamed him for the irregular documents and gave him a choice: resign quietly or be terminated.

He chose termination because resigning felt like admitting he had acted alone.

Before I could process that, Diane called.

Her voice was different.

She admitted that after we left, she and Peter had talked all night. She said Aaron had come to their house late the week before he lost his job and asked about Peter’s old floor safe.

Then came the part none of us expected.

“You put something inside,” she said.

Aaron stared at the phone.

“I don’t remember.”

Peter checked the safe that morning.

Whatever Aaron had hidden was gone.

Only a brass key and a slip of paper remained.

On the paper was one number.

Dad went still.

The name Thomas Harrison surfaced next. Aaron’s uncle had known the safe combination and had worked in government contracting, including briefly at Halberd.

Dad recognized his name from an old inspector general review, but he could not discuss protected material.

Then Marisol sent a photograph.

It showed Aaron in a parking garage five days before he lost his job.

Behind him, reflected in a car window, stood Thomas Harrison, holding a folder marked 417.

Diane’s voice broke through the speaker.

“You saw him that week.”

Aaron denied it.

“He came to our house after you left,” Diane said. “He said you forgot something.”

Dad warned us not to jump past evidence.

Then my phone rang.

Unknown number.

I answered.

“My name is Marisol Vega,” the woman said. “Something changed.”

She had received an alert from an old secure account.

Someone had accessed File 417.

Part 7: Sentinel

Marisol explained that when Aaron cooperated with her, he created a dead-drop archive for evidence he feared would be deleted. She could not open it because the final authentication required a physical key.

The brass key.

But she warned us not to use it.

Opening the archive would alert whoever built the secondary access monitor.

Then she revealed the terrifying part.

The login attempt came from inside a government network.

A message had been attached:

Carter is involved now. Move the family before he remembers Sentinel.

For the first time that night, my father looked shaken.

“What is Sentinel?” Aaron asked.

Dad went pale.

He finally told us Sentinel was an investigation he had worked eighteen years earlier. It involved a network that manipulated defense contracts by placing trusted people inside procurement offices. Careers had been destroyed. Evidence had vanished. The investigation was shut down before they could prove who was behind it.

Then he looked at the image of Thomas.

“Thomas Harrison was not a suspect,” Dad said.

Aaron’s relief lasted less than a second.

“He was one of our confidential sources.”

Diane began to cry.

Then she revealed the truth that shattered Aaron completely.

Thomas was not Aaron’s uncle.

He was his biological father.

Aaron stood frozen, unable to speak.

From the guest room, Caleb woke and called, “Dada.”

I moved toward Aaron and held him, not because I needed him to be strong, but because the story of his life had just broken open.

Then Dad’s phone buzzed again.

A message appeared from Marisol’s secure account.

But Marisol was still on the phone.

She had not sent it.

The message read:

THOMAS HARRISON DIED ELEVEN YEARS AGO.

Then a second line appeared.

SO WHO WAS STANDING BESIDE AARON FIVE DAYS BEFORE HE LOST HIS JOB?
