Arthur Mitchell (Dexter)

Arthur Mitchell, also known as the "Trinity Killer", is a fictional character and the main antagonist of the fourth season of the American Showtime television series Dexter. Arthur presents himself as an unassuming church deacon, high school teacher and family man, but is secretly a highly prolific serial killer who kills to suppress his childhood trauma derived from accidentally causing his sister's death. Agent Frank Lundy of the Federal Bureau of Investigation dubs him the "Trinity Killer" due to mistakenly assuming a recurring pattern of three killings; slitting a woman's femoral artery while naked in a bathtub, forcing a mother of two to jump off a building, and bludgeoning a father of two with a hammer; It is later revealed that the killings are preceded by Arthur burying a young boy alive in cement. Arthur is portrayed by American actor John Lithgow, whose performance was widely praised. He won a Golden Globe Award and a Primetime Emmy Award for his performance. In 2016, Rolling Stone ranked him #34 of their "40 Greatest TV Villains of All Time". IGN ranked him #57 of the "Top 100 Villains".
