Following the IAD investigation, which was conducted by Detectives Pierce Lewis and Don Clarke, Bosch was sent to Hollywood Division and assigned to the homicide desk .

He left retirement and returned to the LAPD at the conclusion of The Narrows . After his return, Bosch was assigned to RHD's Open - Unsolved Unit, a cold case squad . Bosch transferred out of Open - Unsolved and into Homicide Special during the time between Echo Park and The Overlook . </P> <P> During his time in the LAPD as covered in the novels, Bosch was in Hollywood homicide and worked with Frankie Sheehan (Bosch's partner in RHD, who was later murdered in Angels Flight), Jerry Edgar (his longest serving partner) and Kizmin' Kiz' Rider, the other members of Bosch's team in Hollywood homicide . The 2004 Limited Edition DVD that was available with The Narrows included an excerpt of a speech real - life LAPD Chief William Bratton made at the Police Academy, in which he publicly asked Harry Bosch to return from retirement (Connelly was on the stand behind listening to the speech; see Blue Neon Night: Michael Connelly's Los Angeles). In The Overlook, Connelly gave Bratton an approving endorsement (albeit without using his name) for "raising the morale of the rank and file" and for giving "Bosch his job back" (pp. 145--146 of the Vision paperback edition). </P>
