As Stephen Colbert prepares to bid farewell to 'The Late Show,' he's already booked a gig on the CBS drama 'Elsbeth,' where he'll play a late-night host.

Elsbeth, starring Carrie Preston, Wendell Pierce and Carra Patterson, is a murder-of-the-week show. It follows astute but unconventional attorney Elsbeth Tascioni (Preston), who utilizes her singular point of view to make unique observations and corner brilliant criminals alongside the NYPD.

Stephen Colbert will guest star in an upcoming episode of the crime comedy series "Elsbeth," appearing as a late-night frontman.
