What is Flora's next tidying-up project and how does she start it?

Flora feels she still needs to sort out Judith, Adam, and Aunt Ada Doom (the biggest problem) before the farm can be considered truly tidy. She decides to tackle Judith next. Flora invites her to London for some shopping and lunch with an Austrian doctor. Although Judith doesn't reply, Flora instructs her to be ready by nine the next morning. That evening, as Flora is writing a letter to Charles, she receives a wire from Dr. Adoph Mudel, confirming lunch the next day.
