“What do you mean? She told me she would run the numbers. I gave her your cell.”

“I know. She just called me and told me to meet her down in the front plaza. She told me to come alone. What am I getting into here, Rachel?”

Walling laughed before she answered.

“Nothing, Harry. She’s just that way. Very secretive, very cautious. She’s doing you a favor and doesn’t want anybody else to know.”

“You sure that’s all?”

“Yes. And she’ll probably want something in return for the favor. Quid pro quo.”

“Like what?”

“I have no idea, Harry. It might not even be right now. You may just owe her one. Either way, if you want to find out who owns the gun you’ve got, go down and see her.”

“Okay. Thanks, Rachel.”

Bosch disconnected and stood up. He looked behind him. Chu was still not at his desk. Bosch hadn’t seen him yet that morning. He saw Jackson looking at him, and Bosch gave him a signal to meet him at the door. Harry waited until they were out in the hallway before speaking.

“You have a few minutes?” he asked.

“I guess,” Jackson said. “What’s up?”

“Come over here.”

Bosch moved to the glass wall that allowed him to look down on the plaza. He scanned the concrete benches until he saw a woman sitting alone, holding a file. She wore a blazer over slacks and a golf shirt. Bosch could see where the blazer rode up into a sharp ridge behind the right pocket. The woman had a gun holstered under the jacket. It was Wingo. Bosch pointed down at her.

“See the woman on the bench? Blue jacket?”

“Yeah.”

“I’m going down to meet her for a few minutes. I just need you to watch us, maybe take a picture with your phone. Can you do that?”

“Sure. But what’s going on?”

“Probably nothing. She’s from ATF and wants to give me something.”

“So?”

“I’ve never met her before. She didn’t want to come in and told me to come down alone.”

“Okay.”

“I guess I’m just being paranoid. With O’Toole obviously checking on my every move . . .”

“Yeah, I don’t think it helped, you calling him out like you just did. As your defense rep, I don’t think you should be—”

“Fuck him. I gotta go down. You’ll watch?”

“I’ll stay right here.”

“Thanks, pal.”

Bosch hit him on the arm and walked away. Jackson called after him.

“You know you’re the most paranoid guy I know.”

Bosch narrowed his eyes in mock suspicion. “Who told you that?”
