Nobody knew exactly what the number meant.
It referred to the unknown source behind the targeting system.
Someone appeared to know which travelers were carrying cash, where they were going, and when they would be on isolated roads.
Frank fit the profile perfectly.
He was older.
He traveled with legal firearms.
He carried cash.
And he drove alone.
The team equipped his truck with discreet cameras and recorders.
His cash was photographed and tracked.
His permit was completely valid.
Shaw gave him one instruction.
"If they stop you, cooperate."
Frank smiled.
"I've been cooperating with authority since before you were born."
Shaw didn't smile back.
"This isn't a game."
"I know."
"If anything feels wrong, leave."
Frank looked at her.
"Something already feels wrong."
That was when Shaw told him about the second suspect.
Officer Barnes.
They knew Barnes was present during several questionable stops.
But they didn't know whether he was involved.
