Dexter - Episode 1 - Season 2

In the season, the bodies of Dexter's victims are uncovered and an investigation is launched in Dexter's own department to find the killer, dubbed the "Bay Harbor Butcher". During this time, Debra struggles to recover after surviving the Ice Truck Killer's attempt to murder her, and Rita sends Dexter to Narcotics Anonymous meetings when he tells her that he has an "addiction". Sergeant James Doakes (Erik King) stalks Dexter, suspecting that he is connected with the Ice Truck Killer murders. Three new characters are introduced: Keith Carradine appears as Special Agent Frank Lundy, an FBI agent who heads the Bay Harbor Butcher investigation; JoBeth Williams as Rita's mother Gail; and Jaime Murray as Lila Tournay, Dexter's Narcotics Anonymous sponsor.[
