Crime fiction set in 60s/70s: LA, cults, Manson etc

Hi all,

Does anyone have any suggestions for some crime fiction set in 60s/70s – ideally LA / Manson / cult related.

I’ve been watching the Aquarius tv show and the setting really speaks to me (as does Once Upon a Time in Hollywood).

I’ve read all James Ellroy at least twice (one of my favourite authors), also thought about the Lew Archer books, or Inherent Vice (own it but not read yet).

Thanks!
