John Lithgow has a new role to die for – or from.
According to network reps, the former "3rd Rock From The Sun" star will play Walter Simmons, the so-called "Trinity Killer" — one of America's "most prolific" murderers, who has evaded police for decades. He comes under investigation from F.B.I. Special Agent Frank Lundy (Keith Carradine) and Dexter himself (Michael C. Hall).
"Dexter" Season 4 is set to premiere Sunday, September 27 on Showtime.
