Dexter has cast British actor Chris Vance in a multi-episode arc.
The Showtime series, which has had nearly as many casting announcements for its fifth season as Dexter has had victims, will welcome Vance as Cole, an articulate personal aide to a popular business man. He'll appear in at least three episodes, a rep for the series confirms.
Vance, 38, recently guest starred on Burn Notice, and played a memorable role as Whistler on Fox's Prison Break. He joins a line-up of guest stars this season that includes Johnny Lee Miller, April Lee Hernandez, Shawn Hatosy, Julia Stiles, Katherine Moennig and Peter Weller.
