“Get down,” he said and pulled Eleanor down on the seat.

The Mercedes floated by and turned onto Bolsa. He released his grip on her neck. “What the hell do you think you’re doing?” she demanded as she came up.

Bosch pointed at the Mercedes, which was heading away. “They were coming by. You would’ve been made because you went in the office today. What took you so long?”

“They had to track down Rourke. He wasn’t in his office.”

Harry pulled out and started following the Mercedes from a distance of about two blocks. After a long moment composing herself, Eleanor said, “Is he by himself?”

“I don’t know. I didn’t see him get in. I was looking up at the corner for you. I think I heard more than one car door close. I’m sure I did.”

“But you don’t know if Tran was one of them who got in?”

“Right. Don’t know. But it’s getting late. I figure it’s gotta be him.”

Bosch realized then that he might have fallen for the oldest ruse in the surveillance book. Bok, or Tran, or whoever he was, could have simply sent one of his minions in the hundred-thousand-dollar car to draw away the tail.

“What do you think, go back?” he said.

Wish didn’t answer until he looked over at her. “No,” she said. “Go with what we got. Don’t second-guess yourself. You’re right about the time. A lot of banks close at five before a holiday weekend. He had to get going. He was warned by Binh. I think it’s him.”

Bosch felt better. The Mercedes turned west and then north again on the Golden State Freeway toward Los Angeles. The traffic crept slowly into downtown, and then the gold car went west on the Santa Monica Freeway, exiting on Robertson at twenty minutes before five. They were heading into Beverly Hills. Wilshire Boulevard was lined with banks from downtown to the ocean. As the Mercedes turned west, Bosch felt they had to be close. Tran would keep his treasure at a bank near his home, he thought. The gamble had been right. He relaxed a bit and finally got around to asking Eleanor what Rourke had said when she called in.

“He confirmed through the Orange County clerk’s office that Jimmie Bok is Nguyen Tran. They had a fictitious name filing. He changed his name nine years ago. We should’ve checked Orange County. I forgot about Little Saigon.

“Also,” she said, “if this guy Tran had diamonds, he might have used them all up already. Property recs show he owns two more shopping centers like that one back there. In Monterey Park and Diamond Bar.”

Bosch told himself it was still possible. The diamonds could be the collateral for the real estate empire. Just like with Binh. He kept his eyes on the Mercedes, only a block ahead now because rush hour was in full force and he didn’t want to get cut off. He watched the black windows of the car move along the rich street, and he told himself it was heading to the diamonds.

“And I saved the best for last,” Wish announced then. “Mr. Bok, also known as Mr. Tran, controls his many holdings through a corporation. The title of said corporation, according to the records check by Special Agent Rourke, is none other than Diamond Holdings, Incorporated.”

They passed Rodeo Drive and were in the heart of the commercial district. The buildings lining Wilshire took on more stateliness, as if they knew they had more money and class in them. Traffic slowed to a crawl in some areas, and Bosch got as close as two car lengths behind the Mercedes, not wanting to lose the car on a missed light. They were almost to Santa Monica Boulevard and Bosch was beginning to figure they were headed to Century City. Bosch looked at his watch. It was four-fifty. “If this guy is going to a bank in Century City, I don’t think he’s going to make it.”

Just then the Mercedes made a right turn into a parking garage. Bosch slowed to the curb and without saying a word Wish jumped out and walked into the garage. Bosch took the next right and went around the block. Cars were pouring out of office parking lots and garages, cutting in front of him again and again. When he finally got around, Eleanor was standing at the curb at the same spot where she had jumped out. He pulled up and she leaned into the window.

“Park it,” she said, and she pointed across the street and down half a block. There was a rounded structure that was built out to the street from the first floor of a high-rise office building. The walls of the semicircle were glass. And inside this huge glass room Bosch saw the polished steel door of a vault. A sign outside the building said Beverly Hills Safe & Lock. He looked at Eleanor and she was smiling.

“Was Tran in the car?” he asked.

“Of course. You don’t make mistakes like that.”

He smiled back. Then he saw a space open up at a meter just ahead. He drove up and parked.

“Since we started thinking there would be a second vault hit, my whole orientation was banks,” Eleanor Wish said. “You know, Harry? Maybe a savings and loan. But I drive by this place a couple times a week. At least. I never considered it.”

They had walked down Wilshire and were standing across the street from Beverly Hills Safe & Lock. She was actually standing behind him and peeking at the place over his shoulder. Tran, or Bok as he was now known, had seen her earlier, and they couldn’t risk his spotting her here. The sidewalk was clogged with office types that were pouring through the revolving glass doors of the buildings, heading to parking garages and trying to get even a five-minute jump on the traffic, on the holiday weekend.

“It fits though,” Bosch said. “He comes here, doesn’t trust banks, like your friend at State was talking about. So he finds a vault without a bank. Here it is. But even better. As long as you have the money to pay, these places don’t need to know who you are. No federal banking regulations because it isn’t a bank. You can rent a box and only identify yourself with a letter or a number code.”

Beverly Hills Safe & Lock had all the appearances of a bank but was far from it. There were no savings or checking accounts. No loan department, no tellers. What it offered was what it showed in the front window. Its polished steel vault. It was a business that protected valuables, not money. In a town like Beverly Hills, this was a precious commodity. The rich and famous kept their jewels here. Their furs. Their prenuptial agreements.

And it all sat out there in the open. Behind glass. The business was the bottom floor of the fourteen-story J. C. Stock Building, a structure unnotable save for the glass vault room that protruded in a half circle from the first-floor facade. The entrance to Beverly Hills Safe & Lock was on the side of the building at Rincon Street, where Mexicans in short yellow jackets stood ready to valet a client’s car.

After Bosch had dropped Eleanor off and gone around the block, she had watched Tran and two bodyguards get out of the gold Mercedes and walk to the safe and lock. If they thought they might be followed, they hadn’t shown it. They never looked behind them. One of the bodyguards carried a steel briefcase.

Eleanor said, “I think I made at least one of the bodyguards as carrying. The other’s coat was too baggy. Is that him? Yeah, there he is.”

Tran was being escorted by a man in a dark-blue banker’s suit into the vault room. A bodyguard trailed behind with the steel briefcase. Bosch saw the heavy man’s eyes sweep the sidewalk outside until Tran and Banker’s Suit disappeared through the vault’s open door. The man with the briefcase waited. Bosch and Wish also waited, and watched. It was about three minutes before Tran came out, followed by the suit, who carried a metal safe-deposit box about the size of a woman’s shoe box. The bodyguard took up the rear, and the three men walked out of the glass room, out of sight.
