The DrsC have been watching a TV miniseries called Bosch, about an LAPD homicide detective by that name. He works out of precinct in the Hollywood/Beverly Hills area.
I don't believe it was ever broadcast, we're seeing it on Amazon Fire Stick via streaming video. A check of Wikipedia suggests Amazon had the series made for its streaming service.
Bosch is a series of one hour episodes which are effectively chapters in a novel. You really do need to see them in order and without missing any, unlike the typical cop show where each episode is free-standing, from crime to solution in an hour.
Bosch is noir, gritty, and rife with city-level politics. It's very embedded in the Hollywood region of LA with place names, iconic architecture, and atmospherics that create echoes in the skull for a native Angeleno. I spent my earliest years living five blocks from Hollywood and Vine.
The first season deals with a serial killer, and we've finished most of it. So far, it's quite good. A second season is not yet available for binge watchers, although an Internet search suggests it has been, or is being, made.
