Upstairs Downstairs

It is January 1936 and diplomat Sir Hallam and Lady Agnes Holland move into 165 Eaton Place, closely followed by his widowed mother and her wayward sister. But they also need a full serving staff, for which Lady Agnes turns to an agency run by none other than Rose Buck, who used to work at the house. But the arrival of an unwelcome guest puts a strain on relations both, upstairs and downstairs.

It is five months since the Holland's moved into Eaton Place, and Rose is officially installed as housekeeper, while Lady Agnes has maneuvered the house to the center of London society. But storm clouds are gathering in Europe, Lady Persie falls under the spell of Oswald Mosley and his radical political views. Meanwhile, the servants are intrigued by a mysterious new addition to the household.

Lady Persie's life has become increasingly complex, as she continues her illicit affair and pursues her right-wing political interests. Meanwhile, Lady Agnes prepares for motherhood by having her picture taken by celebrated photographer Cecil Beaton and Sir Hallam finds himself dragged into the abdication crisis facing the monarchy and makes a discovery that will change his life forever.
