Echo Park

13 years ago, Harry Bosch and his partner Jerry Edgar had worked on a high-profile case.  Marie Gesto had vanished and is presumed dead.  At the time, they were unable to solve it.  However, Harry never forgot and routinely checked the file out of archives and worked it.  It just so happened that he had it checked out when the district attorney needed it.  The recently arrested Raynard Waits, AKA the Echo Park Bagman, was willing to clear multiple homicides to avoid the death penalty; Gesto was one.  Before he hands over the file, Bosch maneuvers his way into the process.  Harry and his current partner, Kiz Rider, question Raynard Waits.  Bosch thinks the guy is lying.  The DA decides to test Waits.  If he can lead them to the body of Marie Gesto, that would clinch it.  The following day, Bosch, Rider, the DA, Waits' lawyer, Detective Olivas, a deputy sheriff with a shotgun, a camera man, and a forensic investigator drive out to a remote canyon with Raynard Waits in tow.  Wearing cuffs, Waits guides them unerring to a body.  On the way back, Waits was uncuffed so he could ascend a steep slope.  He used the opportunity to snatch a gun, kill two, and seriously wound Kiz.  Waits is on the loose.  Now Harry must find Waits' secret lair before he can kill again.

This book, combined with City of Bones, was the first to be adapted for the Amazon TV series.  Waits is one of the better villains in the series.  Highly recommended.
