The Watcher is an American mystery horror television series created by Ryan Murphy and Ian Brennan for Netflix.

[6] The series follows a married couple who, after moving into their dream home in a fictionalized version of Westfield, New Jersey, are harassed by creepy letters signed by a stalker who goes by the pseudonym "The Watcher".

Similarities between John Graff's character and the List murders include his career as an accountant, attending Lutheran church, and murdering his family members and live-in mother, along with leaving music playing in the house and planning an alibi that would cause the bodies to remain undiscovered for several weeks.
