~ Arthur Mitchell to his victims before he kills them.

Arthur Mitchell, better known as the Trinity Killer, is the main antagonist of the fourth season of the Dexter TV series.

He was portrayed by John Lithgow, who also played Burke in Blow-Out, Lord John Whorfin in The Adventures of Buckaroo Banzai Across the 8th Dimension, B.Z. in Santa Claus: The Movie, Eric Qualen in Cliffhanger, Earl Talbot Blake in Ricochet, Lord Farquaad in Shrek and Lamar Blackburn in The Accountant.

History

In 1959, 10-year-old Mitchell was watching his older sister, Vera, take a shower. Upon seeing him, Vera panicked, slipped and broke the glass screen, cutting her femoral artery and bleeding to death. Arthur's parents blamed him for Vera's death. His mother became extremely depressed, and ultimately killed herself by jumping off a building. Following this, his father, already a heavy drinker, became an alcoholic and frequently beat his son during his drunken rages. Ultimately, his father was bludgeoned to death with a hammer - it is suggested by Mitchell himself.

Ever since, Mitchell has been recreating the deaths of his family in a cyclical series of murders: first he murders a young boy, symbolizing himself; then he kills a young woman by slicing her femoral artery, symbolizing his sister; he forces a middle-aged mother to commit suicide by leaping to her death, symbolizing his mother; and finally he bludgeons a man to death with a hammer, symbolizing his father.

He claims to take no pleasure in killing, and does seem to harbor some remorse; after each murder, he punishes himself by taking a scalding hot shower and goading a drunk into beating him up.

He has killed dozens of people over 30 years, while “hiding in plain sight” as an apparently devoted family man, church deacon and pillar of his community who runs a business building houses for the homeless.

Dexter Morgan decides to make the “Trinity Killer” his next victim after hearing about him from FBI agent Frank Lundy. When he finds Mitchell, Dexter - who has recently become a father - sees that his quarry can apparently balance his family responsibilities with his “secret life” as a serial killer, and decides to learn from him before murdering him. He befriends Mitchell by pretending to need his spiritual counsel; calling himself "Kyle Butler", he claims to have accidentally killed someone and asks for Mitchell's help finding salvation. This strikes a chord in Mitchell, who comes to believe that God sent Dexter to him. Mitchell believes that God is punishing him and attempts suicide, but Dexter saves his life so he can kill him himself later.

Dexter has Thanksgiving with Arthur's family, and discovers that Mitchell is not the loving husband and father he appears to be: he is in fact an abusive tyrant who beats his son, keeps his wife virtually imprisoned in their home and has repressed incestuous feelings for his own daughter. When Mitchell begins hitting his son, Dexter intervenes and nearly kills him. Mitchell decides to get rid of Dexter, and discovers who he really is.

It is eventually revealed that Mitchell has an adult daughter, Christine Hill, from a previous relationship, and that she knows he is a serial killer. Rather than turn him in, however, she covers up for him and even kills Lundy, all so she can win his love. When he learns about Lundy’s death, however, he curses her for bringing the police down on him and says he wishes she had never been born. Devastated, she commits suicide.

Mitchell begins his murder cycle again, kidnapping a young boy. Dexter saves the boy, however, forcing Mitchell to go on the run. Dexter finally subdues Mitchell and prepares to kill him. Mitchell accepts his fate and says that a similar one awaits Dexter, sooner or later. Dexter then bludgeons Mitchell to death with a hammer.

When Dexter returns home, he discovers that his wife, Rita, has been murdered, having bled to death after her femoral artery was slit; she was the Trinity Killer’s last victim.

Trivia

  • Arthur Mitchell is the only main antagonist in the entire series to be killed by Dexter's entire uninterrupted ritual:
    • Dexter subdued Arthur, wrapped him in plastic inside of a kill room Dexter specifically chose for him, the room was surrounded by pictures of Arthur's victims so he could see them all, his blood slide was taken and put into Dexter's blood slide box, and finally dismembered and dumped into the ocean.
  • Arthur is the oldest main antagonist in the series, being 65 years old when Dexter killed him.
  • Arthur is the second person in the entire series to have found out that Dexter uses aliases to hide who he really is, the first being Zoey Kruger.
  • Arthur could possibly be inspired by real life serial killer Dennis Rader, also known as the BTK Killer, for several reasons:
    • Both had secret lives with families, consisting of two children and a wife.
    • Both had specific kill routines they always followed.
    • Both were prominent figures in their church communities.
  • It's not really known as to how Arthur knew not only where Rita Morgan lived but also that she knew Dexter at all. It's possible that Arthur stalked Dexter off-screen at some point for some reason, but it's never been confirmed.
