Mr. Mercedes: Season 3 (DVD)

Beloved local author John Rothstein (Bruce Dern) is found murdered. Hodges (Brendan Gleeson), Holly (Justine Lupe) and Jerome (Jharrel Jerome), along with local police, must track down his killer, but this case is more complex than the cold-blooded killing of an American icon. Unpublished novels of Rothstein's were stolen from his home and they are worth millions. As the case unfolds, the trio learns that, although Brady (Harry Treadaway) may be gone, his depravity lives on in the lives of his victims.
