Michelle Dockery, who beds Turkish diplomats as Lady Mary on Downton Abbey, has signed onto the BBC-Sundance Channel miniseries Restless, about a woman searching for her mother's former lover-slash-spymaster, with flashbacks to 1939 Paris. Dockery will keep to the 1979 half of the drama — she's the daughter — but that's okay, since God willing, Downton will get Lady Mary to 1939 sometime in season twelve.
