He shifted the box to his hip, took out his phone, and snapped two quick photos. One of the diagnostic screen, one of the collared breaker.
Then he kept walking, before the guard could turn around.
He was halfway across the employee parking lot when his phone buzzed in his pocket.
He set the box on the hood of his old pickup truck and looked at the screen.
A text message. Unknown number.
You saw something you shouldn't have.
Caleb read it twice. Then he looked back at the hangar.
High up on the catwalk, framed in the open doorway, a figure stood watching him.
From this distance, he couldn't tell who it was.

40 miles away, in a private suite on the top floor of Hollister Medical Center, the woman from the gate opened her eyes.
The room was quiet, except for the steady beep of a heart monitor. Snow had started falling outside the window.
A young man in a gray suit sat in the chair beside her bed, typing furiously on a tablet. When he saw her stir, he nearly dropped it.
"Miss Ashford. Thank God."
Her name was Vivien Ashford.
She was 39 years old, and she was the chief executive officer of Ashford Aeronautics, the company her grandfather had started in a single rented hangar after the war.
Business magazines put her net worth somewhere north of $4 billion.
Most of the people who worked at Harland Field had never seen her in person. She ran the company from its headquarters in Chicago, and when she traveled, she traveled quietly.
That morning, she had traveled more quietly than ever.
A doctor came in with the toxicology results.
A powerful sedative she had never been prescribed had reacted with her heart medication, slowing her pulse and pushing her toward collapse.
"Another 15 minutes on that concrete," he said, "and this would be a very different conversation. Did you drink or eat anything unusual this morning?"
Vivien thought about it.
"Tea," she said slowly. "From a thermos. The driver handed it to me when he picked me up at the airport."
The doctor wrote that down and left.
Her assistant, Nolan Pierce, stopped typing.
The room felt suddenly colder.
Vivien looked at the ceiling for a long moment. When she spoke again, her voice was flat and controlled.
"Who booked the car, Nolan?"
"I did. Through the usual service. But they sent a different driver. They said the regular man was out sick."
Vivien closed her eyes.
Only four people had known she was coming.
