Nolan was pale, but he kept the device raised. "It's already backed up. I don't have to erase something just because you don't like it."
For an instant the sergeant seemed to understand that his ordinary intimidation had met an obstacle he could not easily remove. Then he laughed and told Nolan he was too young to know what happened to people who crossed the police in Pell Hollow. He threatened the diner's operating license, Nolan's job, and any future complaint the cook might try to make. The customers watched him with faces drawn tight, and the silence that had protected him for years began to feel different.
"One last chance," Knox told Elias. "Walk out, or I'll put you out."
"Take your hand off my shirt," Elias said. "And listen carefully to what happens next."
The sergeant laughed at him. Elias reached slowly toward the pocket of his overalls, announcing the movement before making it. Knox ordered him to keep his hands in sight, but Elias had already produced a black leather credential case. He opened it at chest height, angled it toward the sergeant, and held it steady long enough for the federal identification to be read.
"Special Agent Elias Thornberry," he said. "Federal Bureau of Investigation. You're interfering with an authorized federal investigation. Let go of me."
Across the booth, Marcus displayed his own credentials. His friendly farmer's drawl disappeared, replaced by the level voice he used when explaining facts to a witness. "Special Agent Marcus Greer. And before you start another story, Sergeant, you should know the transaction at the register and your conduct here have both been documented."
Knox released Elias so suddenly that the fabric snapped back against his chest. He stared at the credentials, looked at Marcus, and then glanced toward Nolan's phone. His face reddened as he tried to work out which version of the afternoon might still be useful. The first one he settled on was that the badges were counterfeit.
"Anybody can print those," he said. "You think I'm stupid?"
"You don't have to take our word for it," Elias answered. "There's a publicly listed field office number. Call it, identify yourself, and request verification through the proper channel."
Dale pushed back from the counter. His hands trembled as he took his phone from his jacket, and for a second he nearly sat down again. Then he remembered his daughter's college letter tucked in the glove compartment of his truck. He called the number Marcus provided from the Bureau's public directory, spoke to the person answering, and followed the verification instructions offered by the office.
When he hung up, Dale looked at Knox without his usual lowered gaze. "The office confirmed there's an investigation team here," he said. "They checked the identifying details through their own procedure. Those men aren't pretending."
A low murmur moved through the diner. It was not the sound of victory, not yet, but the sound of people considering what might happen if their own observations mattered. Knox looked from face to face and found no one willing to rescue him from what he had done. Elias straightened his collar and gave him time to understand.
"At twelve twenty, you took an envelope from Mrs. Plumley," Elias said. "You threatened her business if she didn't keep paying. You put one of the bills into a gold clip, and you showed it around the room."
"A donation," Knox answered. "For community outreach."
"Then the department can produce an official receipt and an entry in the appropriate accounts," Marcus said. "We have the serial number of one bill. We documented it before we paid for lunch, and now it's in your possession."
