John Lithgow is joining the cast of Dexter as a regular for season four!

According to Showtime, Lithgow is playing "Walter Simmons, an unassuming, mild-mannered suburbanite who has been living a dual life as one of America's most prolific and deadliest serial killers. Dubbed the Trinity Killer because of his proclivity to kill in threes, he relocates to Miami after being tracked by F.B.I. Special Agent Frank Lundy (Keith Carradine). Brought on to assist in the investigation of Miami's latest serial killer, Dexter Morgan (Michael C. Hall) becomes fascinated with Trinity's unique killing methods and his ability to evade capture for almost three decades." 

The Trinity Killer, huh? Well, Dexter, Rita and baby do make three. Will Simmons be gunning for Dex & Co., or will he really be our antihero's new guiding light?
