Serial Boxes: John Lithgow to Play Killer on Season Four of Showtime's "Dexter"

In a rather surprising twist, John Lithgow (Confessions of a Shopaholic) has been cast in Season Four of Showtime drama Dexter.

Lithgow will appear in all twelve episodes of Dexter's fourth season, which launches September 27th, and will play serial killer Walter Simmons, known by his sobriquet The Trinity Killer, one of America's deadliest murderers who kills in threes and masquerades as an "unassuming mild-mannered suburbanite."

Having relocated to Miami, Simmons will cross paths with Michael C. Hall's Dexter Morgan as Dexter assists F.B.I. Special Agent Frank Lundy (Keith Carradine) investigate the three-decades long crime spree of The Trinity Killer.

(Lithgow is no stranger to playing characters with psychotic tendencies; remember his turn as multiple characters in the 1992 Brian De Palma film Raising Cain?)
