I picked up a book called Poor, Poor Ophelia from BookBub by a woman called Carolyn Weston (never heard of). Book is a police procedural written in the late 60s about a crusty detective sergeant and his bright young offsider, set in Santa Monica, and turned out to be a ripper. Santa Monica is at the western edge of LA and the end of Route 66. The movie Falling Down, with Michael Douglas, climaxed on Santa Monica Pier.
I found in the footnotes that The Streets of San Francisco, the long-running police series with a young Michael Douglas and Karl Malden, was based on this pair, and that she was involved in writing 120 episodes. She grew up in the depression and did all sorts of jobs before writing these. The pilot episode for SOSF was a movie from this novel.
Reminded me of Charles Willeford, who said his best days were as an army rifleman in the Korean War before writing crime novels. He finally got to a series that looking like being a winner with a detective Hoke Moseley. They filmed one, Miami Blues, with Fred Ward as Hoke but had the criminal, played by Alec Baldwin, as the star. Fred Ward was listed down the cast. Also starred a young Jennifer Jason Leigh. Tragically Willeford died shortly after attaining success and the Hoke Moseley series only had 3 or 4 books. There were a lot of lesser-known hard-boiled detective novels written in the 50s and 60s.
Only 3 books in the Weston series though.
Strangely, the only Wikipedia page for her is in French...who do love their noir detective novels. IMO they do it better than anyone else.
