Upstairs Downstairs

Suspecting Persie of passing on information to the Germans, Sir Hallam ends their affair and joins his wife in trying to sober up Pritchard, who soon afterwards goes missing. Rose tells Johnnie that the butler is a reformed alcoholic who is clearly ashamed of his lapse. Casper visits Lady Agnes to tell her he is returning to the States, by which time Sir Hallam is aware of Persie's treachery, just as Lady Agnes is of the affair. With nobody to support her, Persie kills herself before she can be arrested. Beryl and Harry get married, planning to emigrate to America, and Pritchard returns for the wedding. As war is declared, Pritchard becomes an air raid warden, Blanche joins the fire service, and Johnnie is called up. The Hollands agree to stay together in London, but Lady Agnes's trust in her husband is severely compromised.

Persie begins to develop a relationship with Ribbentrop, the King decides to abdicate, Lotta continues to be traumatized and Hellam discovers he has a sister.

After being told it is dangerous for her to have more children, Lady Agnes joins her husband in entertaining American ambassador Kennedy and his family, along with charming Jewish self-made millionaire, Caspar Landry. Pritchard's pomposity forces Mrs Thackeray to resign and move in with relations, though they are unappreciative of her excessive cuisine, and she returns to Eaton Place. Mr Amanjit and Blanche combine to help in the organization of rescuing Jewish children from Germany, whilst Lady Persie, having seen its brutality first hand, ends her flirtation with Naziism and returns home.
