"But he didn't fire from here."
"That's my point. He should have, but he didn't."
"So?"
"He had a minivan. He should have parked it right where we are now. On this exact spot. He should have climbed through into the back seat and opened the sliding door. He should have fired from inside the minivan, Helen. It had tinted windows. The few cars that passed him wouldn't have seen a thing. He should have fired his six shots, with the much easier aim, and the six cartridge cases would have ejected inside the van, and then he should have shut the door and climbed back into the driver's seat and driven away. It would have been a much better firing position and he would have left nothing at all behind. No physical evidence of any kind, because nothing would have touched anything except his tires would have touched the road."
"It's farther away. It's a longer distance to shoot."
"It's about seventy yards. Barr was reliable at five times that distance. Any military sniper is. With an M1A Super Match, seventy yards is the same thing as point-blank range."
"Someone would have gotten his plate number. There's always some traffic. They would have remembered him being here, afterward."
"His plates were covered with mud. Probably on purpose. It would have been a great getaway. In five minutes he would have been five miles away. Much better than threading through the traffic on the surface streets."
Helen Rodin said nothing.
"And he was expecting it to be sunny," Reacher said. "You told me it usually is. Five o'clock in the afternoon, the sun would have been in the west, behind him. He would have been firing out of the sun. That's an absolutely basic preference for a sniper."
"Sometimes it rains."
"That would have been OK, too. It would have washed his tire tracks out of this grit. Either way around, he should have been up here in his van. Every reason in the world says he should have been up here in his van."
"But he wasn't."
"Evidently."
"Why not?"
"We should get back to your office. That's where you need to be now. You've got a lot of strategizing to do."
Helen Rodin sat down at her desk. Reacher walked to her window and looked out into the plaza. Looked for the damaged man in the boxy suit. Didn't see him.
"What strategizing?" Helen asked. "Barr made a choice about where to shoot from, that's all, and it wasn't a great choice, according to you, according to some fourteen-year-old military theory that he probably forgot all about the day he quit the service."
"They don't forget," Reacher said.
"I'm not convinced."
"That's why he walked out on Chapman. Chapman wasn't going to be convinced, either. That's why he asked for me."
"And you are convinced?"
"I'm looking at a situation where a trained sniper passed up an excellent location in favor of a much worse one."
"He used a parking garage in Kuwait City. You said so yourself."
"Because that was a good location. It was directly in line with the apartment building's door. The four guys were walking directly toward him. They went down like dominoes."
"This is fourteen years later. He's not as good as he was. That's all."
"They don't forget," Reacher said again.
"Whatever; how does it make him less guilty?"
"Because if a person chooses a terrible B instead of a great A, there has to be a reason for it. And reasons have implications."
"What was his reason?"
"It had to be a real good one, didn't it? Because he trapped himself inside a building, down at street level, in a congested area, with a much harder shot, in a place whose very nature made it the best crime scene a twenty-year veteran like Emerson has ever seen."
"OK, tell me why he would do that."
"Because he was literally going out of his way to leave every last piece of evidence he could."
She stared at him. "That's crazy."
"It was a great crime scene. Everyone was so happy with how great it was, they never stopped to realize it was way too great. Me included. It was like Crime Scene 101, Helen. It was what they must have given Bellantonio on his first day in college. It was too good to be true, therefore it wasn't true. Everything was wrong with it. Like, why would he wear a raincoat? It was warm and it wasn't raining and he was in a car and he was never outside. He wore it so he could scrape unique fibers off it onto the pillar. Why would he wear those stupid shoes? You look at a pair of shoes like that and you just know they track every last piece of crap around. Why did he shoot out of the dark? So that people would see his muzzle flash and pinpoint the location so they could go up there afterward and find all the other clues. Why would he scrape his rifle on the wall? That's a twenty-five-hundred-dollar purchase. Why didn't he take the traffic cone away with him? It would have been easier just to throw it in the back of his van than leave it there."
"This is crazy," Helen said.
"Two clinchers," Reacher said. "Why did he pay to park? That bothered me from the start. I mean, who does that? But he did. And he did it just so he could leave one little extra clue. Nothing else makes any sense. He wanted to leave a quarter in the meter with his prints on it. Just to tie it all in a nice little bow. To connect it with the shell case, which he probably also left there on purpose."
"It fell in a trench."
"He could have gotten it out. There was plenty of wire lying around, according to Bellantonio's report. It would have taken a second and a half."
Helen Rodin paused. "What's the other clincher?"
"That's easy, once you start looking through the right end of the telescope. He wanted to be looking at the pool from the south, not the west. That was crucial. He wanted to be looking at it lengthwise, not sideways."
"Why?"
"Because he didn't miss, Helen. He fired into the pool deliberately. He wanted to put a bullet in the water, down the long diagonal axis, from a low angle, just like a ballistics tank, just so it could be found later, undamaged. Just so it could tie his barrel to the crime. Sideways wouldn't have worked for him. Not enough travel distance through the water. The bullet would have hit the wall too hard. It would have gotten damaged."
"But why the hell would he do all that?"
Reacher didn't answer.
"Remorse? For fourteen years ago? So he could be found and punished?"
Reacher shook his head. "He would have confessed as soon as they found him. A remorseful person would have been wanting to confess."
"So why did he do all that?"
"Because he was made to, Helen. Simple as that."
She stared at him.
"Someone forced him to do it," Reacher said. "He was forced to do it and he was forced to take the blame for it. He was told to go home afterward and wait for the arrest. That's why he took the sleeping pill. He was probably going crazy, sitting there waiting for the shoe to fall."
Helen Rodin said nothing.
"He was coerced," Reacher said. "Believe it. It's the only logical explanation. He wasn't a lone nutcase. That's why he said, They've got the wrong guy. It was a message. He was hoping someone would pick up on it. He meant they should be looking for the other guy. The guy who made him do it. The guy he feels is more responsible."
Helen Rodin said nothing.
"The puppet master," Reacher said.
Reacher checked the plaza again, from the window. The ornamental pool was about two-thirds full. The fountain was splashing merrily. The sun was out. There were no loiterers visible.
