After it was discovered she was carrying James' child, Sarah was confined to the family estate at Southwold for the duration of her pregnancy. She ran away and presented herself back at 165 just as she was giving birth. Though Sarah miscarried, Lady Marjorie recognised her duty to what would have been the mother of her grandchild, and thought it best that Sarah stayed on at 165 with some light duties to keep her occupied. Sarah was appointed nursery maid to Elizabeth's daughter Lucy and, acting responsibly for once, saved the infant from the incompetent attempts of the elderly family nanny.
However, it wasn't long before Sarah returned to form...

Sarah: What you staring at me for?
Mrs Bridges: You know what I think, Sarah? I think you're eating for two. Am I right?
Sarah: I dunno what you're talking about.
Mrs Bridges: Oh yes you do, my girl! I've noticed – I'm not blind. You've been putting on weight, haven't you? Eating in between meals, dropping trays... Feeling a bit dicky in the mornings, I shouldn't be surprised?
Hudson: Is this true Sarah?
Sarah: Just 'cos I had a rotten bit of cake...
Hudson: Sarah, I demand a simple answer – are you, or are you not, expecting?
Sarah: What if I am?
Mrs Bridges: There are, what did I tell you?
Hudson: I am shocked, Sarah. Shocked to my very fibre.
Sarah: It wasn't my fault.
Mrs Bridges: The cry of the hussy, Mr 'Udson – it's never her fault. You're talking to me and Mr 'Udson, my girl. We know you don't get babies by smelling the flowers.
Sarah: It's not fair, you know. It's always me what's put upon, ever since I first come to this house. Go on, sack me. I don't care – wish I could die. You sack me without a character.
Mrs Bridges: Character? It's a bit late to talk about character!
Hudson: Mrs Bridges...
Mrs Bridges: It's the truth. Now, come along, who is he?
Sarah: I'm not saying.
Mrs Bridges: Don't know which of many, eh?
Hudson: Mrs Bridges, please...
Mrs Bridges: Well... the little trollop!
Sarah: Last time you wasn't 'orrible. You was understanding last time.
Mrs Bridges: Last time was bad luck. This time it looks like it's becoming a bad habit!

Virginia Bellamy (née Hamilton) was the third mistress of 165 Eaton Place. She first met Richard Bellamy in 1916 when she tried to solicit his help in setting up a charity to help war widows – he brusquely palmed her off onto an underling. She again asked for his help in 1918 when her son was being court-martialled for cowardice under fire. Richard's admiration for Virginia's sprit and pluckiness brought the two close together and they married in 1919. Originally intending to live away from Eaton Place, unsubtle pressure from James persuaded the couple to change their plans and, together with Virginia's two earlier children, they took up residence at 165 until the house was sold off in 1930.
