I've probably read all of Connolly's Detective books with Bosch, and the Mickey Haller and Renee Ballard books. I liked the Bosch books the best, as Connolly is a gifted writer. Probably didn't read them all in order as I most likely happened on his book after the first two were written. I bought them before I got my e-reader so quite a few were paperbacks. When I first saw the Bosch series was about two or three years ago, and I watched one show and didn't like it as It didn't accurately portray Bosch, I was disappointed with Titus playing Bosch. I wasn't happy that they changed Bosch's character as one who'd been in the service in Afghanistan as in the books he'd been a tunnel rat in Vietnam, and that was the black echo and the lost light from his experience in the tunnels. Then on more than occassion in the books, Harry liked to get down in a squatting position at the crime scene to get a different view of the scene, which he uses to see the crime from a different viewpoint. Little things like that. So after a year or so I went back to the series with nothing better to do during this stupid shutdown, and I binged the whole six seasons in like four months and the charcter development came along pretty well and Titus grew on me. In the books Maddy didn't get as close to her dad as she did in the series, and his relationship with Elenor was not as estranged as in the books, in the books Elenor was a lot more aloof and more of an enigma type character I suppose the series had to be the way it was to introduce Maddy into the story line more to make the show more interesting. I guess what I'm saying is for the most part the series followed the basic plots of several Bosch books Angel's flight, City of Bones, etc. and the character development of Irving and Elenor and Maddy was deeper than the books got. All in all entertaining and depicted the basic stories that Connolly wrote fairly well, with more character development. Not Bad. The Books I will always appreciated as Connolly is a brilliant writer. In the later books Bosch retires but ends up becoming the old curmudgeon cold case solver in a SF valley precinct. This is kind of portrayed by all of the side stories to the main story like the Daisy Chandler in season six. And old man needing glasses but a wealth of knowledge to give to any young detective willing to learn from him, learning that "Everyone counts or no one counts".
