TNT has ordered a pilot for Good Behavior, a drama series that will serve as the follow-up to Downton Abbey for its star Michelle Dockery. Based on the Letty Dobesh books by Wayward Pines author Blake Crouch, Good Behavior is written by Crouch and Chad Hodge and tells the story of Letty Dobesh (Dockery), a thief and a con artist whose life is always one wrong turn, one bad decision from implosion — which is exactly how she likes it.

Fresh out of prison, Letty is attempting to stay afloat. But when she overhears a hitman being hired to kill a man’s wife, she sets out to derail the job, setting her on a collision course with the killer and entangling them in a dangerous and seductive relationship.

Dockery and the Downton crew are currently shooting the final sixth season of the lauded British period drama. If patterns hold, the final season will air  on the UK’s ITV in the fall, and in early 2016 on PBS’ Masterpiece in the U.S.

Dockery is repped by WME, Anonymous Content and Hamilton Hodell. Hodge is repped by WME and Fuller Downs, and Crouch by Cheng Caplan Company, InkWell Management and Nelson Davis LLP.
