The TV show "Mindhunter"

The series is based on the book Mind Hunter: Inside The FBI's Elite Serial Crime Unit and is largely inspired by reality, but the fact that the two protagonists in the series have fictitious names makes us wonder how much truth and how much fiction is in the Netflix series. But from the point of view of entertainment, the question is irrelevant, because in the end what we want from such a series is to give us tension and twists.
