Don't worry it's not another property show. This TV classic about the upper classes and their downstairs servants returns to the Beeb 35 years after the original ended. This Christmas, BBC One invites viewers old and new across the threshold of one of television's most famous addresses – 165 Eaton Place. Set in 1936, this lavish three-part serial sees diplomat Sir Hallam Holland move into the iconic townhouse along with his wife, Lady Agnes. With the help of former parlourmaid Rose Buck, they launch a whole new era for the sumptuous home at the heart of Upstairs Downstairs. Eileen Atkins, Art Malik, Anne Reid and Adrian Scarborough co-star. Continues tomorrow.
