Downton Abbey star Michelle Dockery has found her follow-up TV role. The actress has been tapped to star in TNT drama Good Behavior, which has landed a pilot order at the Turner-owned cable network. In the new show, Dockery will star as Letty Dobesh, a thief and con-artist whose life is always one wrong turn, one bad decision from implosion — which is just 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. The role will mark her follow-up to Masterpiece’s Downton Abbey, which has earned her three straight Emmy nominations.
