It isn't really binge watching I know but if you get a chance watch the limited series I Will Be Gone In The Dark. It is the story of a very talented magazine and crime blog writer who becomes obsessed with a series of sexual assaults and murders that she is convinced are all committed by the same person. The assaults/murders occurred in California in the 70s and 80s and her investigation takes place in over two decades later. In investigating for the article and then a book she begins to author she speaks to as many people who had anything to do with the original crimes as possible but did as much new investigation that she could. You see what a creative investigative mind she had so that the investigation was able to go in many different directions. Particularly as the crimes were not at first connected themselves in any way. She also was a very down to earth person and mother who was married to the comedian Pat Patton Oswalt. I was totally absorbed by the series. The below is an NPR interview interviewing her husband and the director of the series.
