Angie nodded. "Yes. On his cell phone. He was telling me he was about to leave for town when whoever it was came bursting inside."

Joanna looked at Dick Voland. "There's only one set of tracks showing," she told him. "Depending on when the rain ended, they could either be corning or going. Since the Hummer isn't anywhere in sight, I'd say going. You drive on in as far as the trailer. Try to stay far enough off the roadway itself that you don't disturb any of the tracks."

"What are you going to do?" Voland asked.

"Walk," Joanna said. "Something may give me a clue as to which way he was going or how long ago he left."

"Wait a minute," Voland objected. "What if they're still in there?"

"With the Hummer gone, I doubt it," Joanna returned. "But that's a risk we're going to have to take."

"Wait," Angie said. "I'll come with you."

"No you won't," Joanna told her. "You'll stay in the back of the Blazer until either Dick or I give the word that it's safe. Understand?"

Nodding, Angie subsided back in the seat. Joanna slammed the door on Dick Voland's next volley of objections and turned her attention back to the tire tracks. They were easy to follow. They led directly around the cemetery and toward the little boulder-free clearing where the trailer was parked. Halfway there, a second set of tracks-from the same tires-suddenly overlaid the first.

Joanna held up her hand and signaled for Dick to stop the Blazer long enough for her to sort out what had happened. The original set continued on toward the trailer. The second set-definitely more recent than the first-headed off toward the south. Motioning Dick to stay where he was, Joanna walked closer to the trailer. She was concentrating so hard on the tracks that only a hint of movement registered in her peripheral vision. Because she was already filled with apprehension, the movement, combined with a sudden whack of metal on metal, was enough to send her diving for cover behind a boulder, drawing her Colt 2000 as she did so.

At once, Voland killed the engine on the Blazer. In the sudden hush that followed the whack came again. "Did you see something?" Dick asked a moment later as, nine-millimeter in hand, he dropped to the ground beside her.

Feeling stupid, Joanna didn't want to answer. "It's the door," she said. "The open door to the trailer blowing in the wind."

"Cover me," Voland said. "I'll go on up and check it out."

"No," Joanna said. "We'll both-" She stopped short. Had she not been looking at Dick Voland just then, she might have missed it entirely. "Look!" she said, pointing.

"Look at what? I don't see anything."

"Footprints," she said. She crawled around her chief deputy to examine the set of footprints that had been left in the soft sand. They looked as though they had been left by a pair of worn sneakers, and they led directly from the brush toward the trailer. The prints from the right foot were distinct and clear. The ones made by the left foot were blurry, less defined. A foot or so off to the left of them was a third track of some kind-a round hole poked in the dirt at regular intervals.

"Whoever left these tracks may be hurt."

"What makes you say that?" Voland asked.

"He's using a cane or a crutch," Joanna said. "Most likely a cane."

Voland eyed her quizzically. "How can you tell?"

In order to handle the livestock chores on the High Lone-some, Joanna had found it necessary to have a hired hand. An octogenarian neighbor of hers, Clayton Rhodes, had volunteered for the job. The previous winter, though, after slipping on an ice-glazed pile of cow dung, Clayton had been forced to use a cane for almost two weeks. During that time, Joanna had noticed the tracks he had left behind on trips from his pickup to the barn, to the house, and back again. Those tracks and these were inarguably similar.

"Experience," she said, without pausing to explain. "Come on. Let's check out that trailer."

"Wait a minute," Voland warned. "Don't forget a gunman inside that trailer can shoot through those aluminum walls as easily as shooting through pop bottles."

''Right," Joanna said. "So what do you suggest?"

"Split up and stay low."

Joanna crept forward, following the tracks, while Voland moved off to the left. The tracks on the ground were easy enough to follow. They led directly to the wooden step outside the trailer's open door. There they disappeared.

"Mr. Hacker," Joanna called, ducking behind a tree trunk little more than a few feet from the door. "Are you in there?"

Joanna waited for the better part of a minute, but there was no response other than the intermittent whack of the door on the trailer's metal siding. She watched while Voland circled around until he was behind the trailer. Finally, when he signaled, they both moved forward.

They arrived at the trailer almost simultaneously, with her approaching one of the front windows just as Voland's face appeared in one at the back. "Looks like nobody's home," Voland called.

Still taking care to dodge the footprints, Joanna walked close enough to the trailer to poke her head in through the door. The interior of Dennis Hacker's camper looked as though it had been hit by a cyclone. Shards of broken glass were everywhere, along with shattered pieces of molded black plastic that looked as though they had once been part of a cell phone. There were also several reddish stains that resembled smears of blood.

Sickened, sure that she had once again arrived at the scene of a crime too late to do any good, Joanna backed away. "If you're looking for signs of a struggle," she called back to Dick, "here they are."

While Voland hurried around the trailer to peer in through the door, Joanna walked away, following two new sets of foot-prints. Now the person wearing the sneakers had been joined by someone else, by someone wearing what Joanna surmised to be hiking boots. Traveling together, the two pairs of prints headed around the trailer in a counterclockwise direction before disappearing into a vehicle-the same wide-tracked vehicle whose tracks Joanna had followed before.

"I'll go back to the Blazer and radio for a crime scene technician ..."

Joanna knew Dick Voland was speaking to her, but she barely heard him. If the vehicle-presumably Dennis Hacker's Hummer-had left the trailer with two passengers instead of one, maybe Joanna and Dick Voland weren't too late after all.

"Come on," she called urgently to Dick. "Go get the Blazer. They're headed south."

"Together?" Dick asked, jogging up behind her.

"That's my guess."

Voland started toward the Blazer. Then, to Joanna's annoyance, he turned and came back. "What about the girl?" he asked.

"Angie?" Joanna returned. "What about her?"

"She got us here," Voland said. "I'll give her that much, but if we're heading into an armed confrontation ..."

Without bothering to listen to the rest of the sentence, Joanna knew he was right. As an officer of the law, her duty was to keep civilians out of danger rather than leading them into it. She nodded. "Tell Angie to wait in the cemetery. Have her duck down behind that rock wall and stay there until we come back."

"With pleasure," Voland replied. He hurried away.

Thinking that settled the issue once and for all, Joanna turned back to the tire tracks. She had gone no more than a few yards when she heard running footsteps pounding behind her. "Joanna, wait," Angie called. "Let me come, too."

Annoyed that Dick Voland hadn't stated the case plainly enough, Joanna turned to face her friend. "Look, Angie," she said sharply, "you can't come with us. It's too dangerous."

Angie stopped in her tracks. Behind her came the Blazer with a smiling Dick Voland at the wheel. A single glimpse of the man's face was enough to let Joanna know that he hadn't tried to stop Angie, not really. If he had, he would have and she wouldn't be there. No, letting her go had been a deliberate ploy on Dick Voland's part. He was testing Joanna again, wanting to know whether or not she was tough enough to call the shots and make the right choice between friendship and duty.

Except this time there was no choice to make. As sheriff and as a sworn police officer, Joanna Brady's responsibility was blazingly clear-to serve and protect. "Go back," she said.

"Why should I?" Angie objected. "I'm wearing a bullet-proof vest."

"You may have a vest," Joanna conceded "but that still leaves a whole lot of you unprotected and exposed to danger, which is unacceptable. You brought us this far, Angie. We're grateful for that, but there's no telling what's up ahead. We're armed. You're not."

"But ..."

"No buts," Joanna insisted. "What if there's a shootout? What if, in trying to take care of you, we can't protect Mr. Hacker? Your being in the way at a critical moment could make all the difference-the difference between life and death. Go now, please."
