Bosch nodded, hoping she would keep talking.

“But back then it didn’t lead to anything,” she said. “They never came up with a suspect. Who’d they come up with on the cold hit?”

“We’ll get to that in a second,” Bosch said. “What I meant was, did you submit to the lab from any other cases you were working? Or was this all you had going?”

“No, that was it,” Shuler said, his eyes squinting in suspicion. “What’s going on here, Harry?”

Bosch reached into his inside coat pocket and pulled out the hit sheet. He slid it across the table to Shuler.

“The hit comes back to a sexual predator who would look real good for this except for one thing.”

Shuler unfolded the sheet and he and Dolan leaned together to read it, just as Bosch and Chu had earlier.

“What’s that?” Dolan said, not picking up on the significance of the birth date yet. “This guy looks perfect.”

“He’s perfect now,” Bosch said. “But back then he was only eight years old.”

“You’re kidding,” Dolan said.

“What the fuck?” Shuler added.

Dolan pulled the sheet away from her partner as if to see it clearer and to double-check the birth date. Shuler leaned back and looked at Bosch with those suspicious eyes.

“So you think we fucked up and mixed up cases,” he said.

“Nope,” Bosch said. “The lieutenant asked us to check out the possibility but I don’t see any fuckup on this end.”

“So it happened at the lab,” Shuler said. “Do you realize that if they screwed things up at regional, every defense lawyer in the county is going to be able to raise doubt about DNA matches that come out of there?”

“Yeah, I kind of figured that,” Bosch said. “Which is why you should keep this under your hats until we know what happened. There are other possibilities.”

Dolan held up the hit sheet.
