“I pulled the package on Wilbert Dobbs. And I looked at the sign-out log. You pulled the package this morning and you took the bullets. You took the bullets from Sheehan’s service nine, the bullets he shot Dobbs with five years ago, and you turned three of them in to ballistics saying they were the bullets from the Howard Elias autopsy. You set him up to take the fall. But it’s your fall, Chastain.”

He checked the mirror. Chastain’s face had changed. The news Bosch just delivered had hit like the flat side of a shovel in the face. Bosch moved in for the finish.

“You killed Elias,” he said quietly, finding it hard to pull his eyes away from the mirror and back onto the road. “He was going to put you on that stand and expose you.

“You lucked out,” he continued. “The Dobbs case. It fit perfectly. You came across Sheehan’s threat in the files and took it from there. You had your patsy. A little research on the case and a little maneuvering here and there and you got to handle the autopsy. That gave you the bullets and all you had to do was switch them. Of course, the coroner’s ID markings on the bullets would be different but that discrepancy would only come up if there was a trial, if they took Sheehan to trial.”

“Bosch, shut up! I don’t want to hear anymore. I don’t — ”
