Plot
It is the spring of 1924, and Georgina returns from New York, having stayed with Elizabeth in her city apartment. Meanwhile, Daisy gets annoyed when Lily is given time off to go shopping by Mr Hudson. A few days later, while at the Wembley Exhibition, Georgina spots Hudson and Lily together holding hands. That evening she tells Virginia what she saw, and Virginia then asks Rose if Lily is seeing any one. Rose says she knows nothing, but then goes to see Lily and asks her if she is going out with Mr Hudson. Lily confirms this and tells Rose how he has taken her to concerts and museums. Very soon, the whole house knows what has been going on. Hudson explains to Mrs Bridges that Lily brings him hope and joy, and he tells Virginia that he has "very deep feelings" for her. Mrs Bridges is upset, as she and Hudson had agreed that one day they would marry. Hudson soon decides to resign and gives four weeks notice. Hudson wants to go with Lily on Sunday to see her mother in Banbury to ask for Lily's hand in marriage. However Lily cannot bring herself to tell him that she does not love him. On the Sunday morning, having spoken to Georgina, Lily talks to Hudson, and deliberately hurts him by saying insulting him. The following morning, Lily leaves 165, Eaton Place without telling anyone and goes back to live with her mother. She leaves a note for Mr Hudson, explaining she did not mean the hurtful things she said the day before; she had only wanted to stop him caring for her. Hudson withdraws his resignation, and Virginia writes a good reference for Lily. References
