Petey probably wouldn't have been familiar with the term "the Stockholm principle," but he was a skillful-enough manipulator that he would have understood it. After a period of time, captives grow weary of their roller-coaster emotions. Grateful to be shown small kindnesses, they tend to accept their situation and to bond with their captors.

That would have been Petey's hope. But of course he wasn't accustomed to providing for a wife and son. The breakfast would have quickly disappeared, and then there'd have been the problem of what to do about lunch and supper. Petey wouldn't have thought that far ahead, but even if he had, how was he going to keep hamburgers and fries from spoiling, and what about a way to reheat them? He needed to buy a cooler, a camping stove, pots and pans and… What had started as an urge to take my place suddenly didn't have the gratification it had promised. Everything was getting too complicated. Why not admit that he'd made a mistake and chuck the whole business? Why not do what he wanted with Kate and Jason, kill them and the driver in the trunk, hide their bodies, drive into the nearest big town, abandon the car, buy a bus ticket, and adios?

The thought made me shudder. No, that's how Lester Dant would have acted, I tried to assure myself. Lester Dant would have killed Jason right away, then driven Kate to a secret spot and dumped her body down a ravine when he got tired of abusing her. He certainly wouldn't have taken the time and the risk to lay a false trail all the way to Montana. That only made sense if Petey had abducted them, if he was determined to take over my life and make Kate and Jason his family.

But his patience would have been sorely tested. The only way he could have felt at ease enough to go to sleep was by putting Kate and Jason back into the trunk so they wouldn't try to escape while he was dozing. The shade of the trees would have prevented the trunk from becoming lethally hot. Still, Petey would have had no idea how long he might sleep. He'd have loved eight hours. Even with numerous ventilation holes, Kate, Jason, and the man whose car he'd stolen probably wouldn't have been able to survive that long in the trunk without the lid being opened periodically to vent carbon dioxide. Two people, though, would have a chance. There'd have been one-third more air for them if…

That's when I knew that Petey had deliberately killed the second driver, whereas the first death had been an accident.

Sleep. I could barely keep awake. But as I opened a back door, staring at my suitcase, knapsack, laptop computer, and printer, I realized that I was going to have to put them in the front seat so I could stretch out in the back. It would have annoyed Petey to move his four suitcases. Another complication. Another nuisance. In addition, I was going to have to disable the car's interior light so I could leave a back door open and stretch my legs while I slept-to prevent the car's battery from dying. One more damned thing to do.

No, this wouldn't have been at all like what Petey had wanted.

The sound of a passing vehicle startled me awake. I sat up sharply. Before I checked my watch, the angle of the sun told me that the time was late afternoon. Out of sight from the trees, the vehicle kept bumping along the dirt road. My mouth felt pasty as I got out of the backseat and peered through the trees, seeing that the vehicle was a pickup truck, a rancher in a hurry to get somewhere. My back was sore.

Thus Petey's nervous schedule would have resumed: checking on his captives, lifting them out so they could relieve themselves and wash their faces in the river. At some point, he would have had to take care of himself. His clothes would have felt grimy. Probably he changed them for some of the clothes that he'd stolen from me. Perhaps he'd felt angry as the rumblings in his stomach told him that he had to start thinking about getting more food for everybody. He couldn't go on like this. Either he had to find a place in which to settle or he would have to kill Kate and Jason for creating his problems.

No! The only way I could shove that mind-threatening thought away was by imagining how Kate and Jason might have reacted to Petey's growing impatience. Kate's training would have told her that she had to accommodate Petey as best she could, to make things less complicated for him, to ease the strain he felt.

"I can try to wash these dirty clothes in the river. Tie me to a tree and watch me on the bank. That way, you'll be sure I can't run away. What about these suitcases you moved to the front? Why don't I return them to where they were? There's a lot of housekeeping I can take care of."

Jason might have caught on by then. He might have understood what Kate was doing and tried his best to appear the obedient son. Reinforce Petey's fantasies. Make him believe that his risk and effort were worthwhile. That was the only way they were going to stay alive. In a way, it was the captives trying to make the captor fall into the Stockholm syndrome.

Petey would have been too close to where he'd abandoned the Caprice. The new vehicle he was driving would soon have been reported missing. Maybe it had license plates from several states away, suggesting that the driver had a distance to go before arriving home and wouldn't be reported missing until at least the end of the day. All the same, Petey wouldn't have been able to depend on that. He needed to get on the move. But he didn't dare show the car until darkness made him invisible. That meant waiting to get food for Kate and Jason. But it also meant that Kate and Jason had more time to talk with him, a chance to try to bond with him, to personalize themselves, so that killing them wouldn't be easy.

Petey brought out the rope and the duct tape.

"I need to ask you to do something," Kate said.

Petey tied her hands behind her back.

"Please, listen," Kate said. "I understand why you need to put the duct tape over our mouths. You're afraid we'll yell and make somebody call the police."

Petey tied her feet.

"Please," Kate said. "It's almost impossible to breathe when the trunk gets hot. When you press the duct tape across our mouths, I'm begging you to…"

Petey tore off a section of tape.

"Please. It won't threaten you if you cut a small hole where our lips are. We still won't be able to yell. But we'll be able to breathe better."

Petey stared at her.

"You promised you'd take care of us," Kate said. "What good are we to you if we're dead?"

Petey's harsh eyes were filled with suspicion. He pressed the tape over her mouth and set her in the trunk. He did the same to Jason. Kate looked beseechingly up at Petey, who reached to close the trunk, paused, then pulled out a knife and slit the duct tape over their lips.

I hoped. But when darkness finally came and I returned to the interstate, I couldn't repress my unease that I was totally wrong about my reenactment of what had happened. In Wyoming, I came to another fork in the interstate. My palms broke out in a sweat as I tried to decide what to do next. I could retrace my route on 25, eventually returning to Denver, or I could veer east on the continuation of 90, heading into the Black Hills of South Dakota. I couldn't imagine Petey returning to Denver. But the Black Hills would surely have appealed to him. Plenty of places in which to hide.
