Since its release in April, Netflix's true crime drama "Baby Reindeer" has become a huge pop culture phenomenon.
The series was created by its lead actor, Richard Gadd, who plays a fictional version of himself called Donny Dunn. It's based on his experiences with being stalked by a woman earlier in his career, when he was trying to make it as a comedian.
Buzz around the show quickly snowballed, as audiences tried to track down the real-life people the show's characters are based on, particularly Dunn's stalker, Martha Scott, and his abuser, Darrien.
Forensic psychologist, Dr. Ruth Tully, told Business Insider that true crime shows like "Baby Reindeer" can turn audiences into armchair detectives because the genre blurs the lines between entertainment and reality.
The speculation culminated on Thursday when Piers Morgan interviewed Fiona Harvey, a 58-year old Scottish woman who fans outed as "the real Martha Scott."
Here's a complete timeline of the "Baby Reindeer" drama.
