He was sweating heavily twenty yards after getting out of the car. And already regretting his decision. He was in the middle of nowhere, on foot on a major highway, and the slowest vehicles were doing sixty. Nobody was going to want to stop for him. Even if they did want to, give them a little reaction time, give them a little time to check their mirrors, a little braking time, they'd be more than a mile away before they knew it, and then they'd shrug their shoulders and speed up again and keep on going. Dumb place to hitch a ride, they'd think.

It was worse than dumb. It was suicidal. The sun was fearsome and the temperature was easily a hundred and twelve degrees. The slipstream from the cars was like a hot gale, and the suction from the giant trucks wasn't far from pulling him off his feet. He had no water. He could barely breathe. There was a constant stream of people five yards away, but he was as alone as if he was stumbling blind through the desert. If a state trooper didn't come by and arrest him for jaywalking, he could die out there.

He turned and saw the Cadillac, still sitting inert on the shoulder. But he kept on walking away from it. He made it about fifty yards and stopped. Turned to face east and stuck out his thumb. But it was hopeless, like he knew it would be. After five minutes, a hundred vehicles, the nearest thing he'd gotten to a response was some trucker blasting his air horn, a huge bass sound roaring past him with a whine of stressed tires and a hurricane of dust and grit. He was choking and burning up.

He turned again. Saw the Cadillac lurch backward and start up the shoulder toward him. Her steering was imprecise. The rear end was all over the place. It was close to slewing out into the traffic. He started walking back to it. It came on to meet him, fishtailing wildly. He started running. He stopped alongside the car as she braked hard. The suspension bounced. She buzzed the passenger window down.

"I'm sorry," she said.

He didn't hear it in the noise, but he caught the shape of the words.

"Get in," she said.

His shirt was sticking to his back. He had grit in his eyes. The howl of sound from the road was deafening him.

"Get in," she mouthed. "I'm sorry."

He got in. It felt exactly the same as the first time. The air roaring, the freezing leather seat. The small cowed woman at the wheel.

"I apologize," she said. "I'm sorry. I said stupid things."

He slammed the door. There was sudden silence. He put his hand in the chill stream from the vents.

"I didn't mean them," she said.

"Whatever," he said back.

"Really, I didn't mean them. I'm just so desperate I can't tell right from wrong anymore. And I'm very sorry for the thing about the sex. It was a crass thing to say."

Then her voice went small. "It's just that some of the guys I've picked up, I figured that was what it was going to have to be."

"You'd have sex with them so they'd kill your husband?"

She nodded. "I told you, I'm trapped and I'm scared and I'm desperate. And I don't have anything else to offer."

He said nothing.

"And I've seen movies where that happens," she said.

He nodded back.

"I've seen those movies, too," he said. "They never get away with it."

She paused a long moment.

"So you're not going to do it," she said, like a statement of fact.

"No, I'm not," he said.

She paused again, longer.

"O.K., I'll let you out in Pecos," she said. "You can't be out there walking. You could die in heat like this."

He paused too, much longer than she had. Then he shook his head. Because he had to be somewhere. When you live on the road, you learn pretty quick that any one place is about as good as any other place.

"No, I'll come with you," he said. "I'll hang out a couple of days. Because I'm sorry about your situation, Carmen. I really am. Just because I won't walk in and shoot the guy doesn't mean I don't want to help you some other way. If I can. And if you still want me to, that is."

She paused another beat.

"Yes, I still want you to," she said.

"And I want to meet Ellie. She looks like a great kid, from her picture."

"She is a great kid."

"But I'm not going to murder her father."

She said nothing.

"Is that completely clear?" he asked.

She nodded.

"I understand," she said. "I'm sorry I asked."

"It's not just me, Carmen," he said. "Nobody would do it. You were fooling yourself. It wasn't a good plan."

She looked small and lost.

"I thought nobody could refuse," she said. "If they knew."

She turned and watched the traffic coming up behind her. Waited for a gap. Six cars later, she pulled back onto the highway and gunned the motor. Within a minute she was doing eighty again, passing one car after another. The trucker who had used his air horn as he left Reacher in the dust lasted seven whole minutes, before she reeled him in.

The Crown Victoria made it to the destination the woman had selected within eighty minutes. It was an inch-wide empty brown stain on the map, and it was a forty-mile-wide empty brown stain in reality. One road ran through it, meandering roughly north and east in the lee of distant mountains. Hot, lonely, valueless country. But it had all the features she had predicted. It would serve her purposes. She smiled to herself. She had an instinct for terrain. "O.K.," she said. "First thing tomorrow. Right here."

The big car turned and headed back south. The dust from its tires hung in the air for long minutes and then floated down to the powdery ground.

Carmen came off the highway just short of Pecos and speared south on a small county road that led down into total emptiness. Within five miles, they could have been on the surface of the moon. "Tell me about Echo," he said.

She shrugged. "What's to tell? It's nothing. When they were first mapping Texas a hundred years ago, the Census Bureau called a place settled if it had more than six people to the square mile, and we still don't qualify. We're still the frontier."

"But it's very beautiful," he said.

And it was. The road was snaking and diving through endless contours, with red rock canyons either side of it, tall and noble to the east, fractured and pierced to the west, where ancient streams had sought the banks of the Rio Grande. Tall dry mountains reared beyond, with an immense technicolor sky above, and even in the speeding car he could sense the stunning silence of thousands of square miles of absolute emptiness.

"I hate it," she said.

"Where will I be?" he asked.

"On the property. In the bunkhouse, I guess. They'll hire you for the horses. We're always a man short. You show up with a pulse, they'll be interested. You can say you're a wrangler. It'll be a good disguise. It'll keep you close by."

"I don't know anything about horses."

She shrugged. "Maybe they won't notice. They don't notice much. Like me getting beaten half to death."

An hour later, they were tight for time. She was driving fast enough that the tire squeal from the curves was more or less continuous. They came up a long steep grade and then turned out between two rock pillars on a peak and suddenly there was flat land below them as far as the eye could see. The road fell away like a twisted tan ribbon and was crossed twenty miles ahead by another, just visible through the haze like a faint line on a map. The distant crossroads was studded with a handful of tiny buildings, and apart from them and the two roads there was no evidence humans had ever lived on the planet.

"Echo County," she said. "Everything you see, and a lot more besides. A thousand square miles, and a hundred and fifty people. Well, a hundred and forty-eight, because one of them is sitting right here with you, and one of them is still in jail."
