Now, not long before sunup, the Mississippi Border Checkpoint appeared ahead of them, a twinkling village of lights in the predawn darkness. Even at this hour, the lines were long, mostly tanker trucks headed north to St. Louis or Chicago. Guards with dogs and Geiger counters and long mirrors on poles moved up and down the lines. Wolgast pulled in behind a semi with Yosemite Sam mud flaps and a bumper sticker that read: I MISS MY EX-WIFE, BUT MY AIM IS IMPROVING.

Beside him, Doyle stirred, rubbing his eyes. He sat up in his seat and looked around. “Are we there yet, Dad?”

“It’s just a checkpoint. Go back to sleep.”

Wolgast pulled the car out of line and drew up to the nearest uniform. He rolled down the window and held up his credentials.

“Federal agents. Any way you can wave us through?”

The guard was just a kid, his face soft and spotted with pimples. The body armor bulked him up, but Wolgast could tell he was probably no more than a welterweight. He should be back at home, Wolgast thought, wherever that was, snug in bed and dreaming of some girl in his algebra class, not standing on a highway in Mississippi wearing thirty pounds of Kevlar, holding an assault rifle over his chest.

He eyed Wolgast’s credentials with only vague interest, then tipped his head toward a concrete building sitting off the highway.

“You’ll have to pull over to the station, sir.”

Wolgast sighed with irritation. “Son, I don’t have time for this.”

“You want to skip the lines, you do.”

At that moment, a second guard stepped into their headlights. He turned his hips to their vehicle and unslung his weapon. What the fuck, Wolgast thought.

“For Pete’s sake. Is that really necessary?”

“Hands where we can see them, sir!” the second man barked.

“For crying out loud,” Doyle said.

The first guard turned toward the man in the headlights. He waved his hand to tell him to lower his weapon. “Cool it, Duane. They’re feds.” The second man hesitated, then shrugged and walked away.

“Sorry about that. Just pull around. They’ll have you out fast.”

“They better,” Wolgast said.

In the station, the OD took their credentials and asked them to wait while he phoned in their ID numbers. FBI, Homeland Security, even state and local cops; everybody was on a centralized system now, their movements tracked. Wolgast poured himself a cup of sludgy coffee from the urn, took a few halfhearted sips, and tossed it in the trash. There was a No Smoking sign, but the room reeked like an old ashtray. The clock on the wall said it was just past six; in about an hour the sun would be coming up.
