The OD stepped back to the counter with their credentials. He was a trim man, nondescript, wearing the ash gray uniform of Homeland Security. “Okay, gentlemen. Let’s get you on your merry way. Just one thing: the system says you were booked to fly to Denver tonight. Probably just an error, but I need to log it.”

Wolgast had his answer ready. “We were. We were redirected to Nashville to pick up a federal witness.”

The duty officer considered this a minute, then nodded. He typed the information into his computer. “Fair enough. Raw deal, they didn’t fly you. That must be a thousand miles.”

“Tell me about it. I just go where I’m told.”

“Amen, brother.”

They returned to their car, and a guard waved them to the exit. Moments later they were back on the highway.

“Nashville?” Doyle asked.

Wolgast nodded, fixing his eyes on the road ahead. “Think about it. I-55 has checkpoints in Arkansas and Illinois, one just south of St. Louis and one about halfway between Normal and Chicago. But you take 40 east across Tennessee, the first checkpoint is all the way across the state, at the I-40 and 75 interchange. Ergo, this is the last checkpoint between here and Nashville, so the system won’t know we never went there. We can make the pickup in Memphis, cross into Arkansas, bypass the Oklahoma checkpoint by driving the long way around Tulsa, pick up 70 north of Wichita, and meet Richards at the Colorado border. One checkpoint between here and Telluride, and Sykes can handle that. And nowhere does it say we went to Memphis.”

Doyle frowned. “What about the bridge on 40?”

“We’ll have to avoid it, but there’s a pretty easy detour. About fifty miles south of Memphis there’s an older bridge across the river, connects to a state highway on the Arkansas side. The bridge isn’t rated for the big tankers coming up from the N.O., so it’s passenger cars only and mostly automated. The bar-code scanner will pick us up, and so will the cameras. But that’s easy to take care of later if we have to. Then we just work our way north and pick up I-40 south of Little Rock.”

They drove on. Wolgast thought about turning on the radio, maybe getting a weather report, but decided against it; he was still alert, despite the hour, and needed to keep his mind focused. When the sky paled to gray, they were a little north of Jackson, making good time. The rain stopped, then started again. Around them the land rose in gentle swells like waves far out to sea. Though it seemed like days ago, Wolgast was still thinking about the message from Sykes.

Caucasian female. Amy NLN. Zero footprint. 20323 Poplar Ave., Memphis, TN. Make pickup by Saturday noon latest. No contact. TUR. Sykes.

TUR: travel under radar.

Don’t just catch a ghost, Agent Wolgast; be a ghost.
