Miss Clack doesn't see Rachel at all for a month after Lady Verinder's death.
Lady Verinder has made her brother-in-law, Mr. Ablewhite, Rachel's guardian in her will, until Rachel turns twenty-one or until she gets married.
Mr. Ablewhite knows that Rachel is engaged to Godfrey and is happy about it.
In the meantime, Rachel doesn't want to stay at the house in London, because it reminds her of her mother's death, and the house in Yorkshire reminds her of the Moonstone.
So, Mr. Ablewhite proposes that Rachel stay in a rented house in Brighton (a seaside town) for a while with Mrs. Ablewhite, and Godfrey will be able to join them easily from London by train whenever they need him.
Mrs. Ablewhite is too lazy to take care of finding a rental house or hiring servants for it, so she asks Miss Clack to do it.
Miss Clack talks to Rachel before going to Brighton and finds that Rachel has changed a lot since her mother's death.
For one thing, Rachel is a lot more polite to Miss Clack.
She even apologizes for having been disrespectful to her in the past.
Miss Clack is delighted, and plans to make a real Christian out of Rachel.
She goes to Brighton to hire the servants, making sure that they're all good, solid Christians.
She even puts religious books and tracts on the table in the house so that Rachel will see them when she arrives.
Mr. Bruff accompanies Rachel and Mrs. Ablewhite to Brighton and stays for dinner.
Miss Clack is not happy – she doesn't think Mr. Bruff is a good influence on Rachel.
Miss Clack takes Rachel to church the next morning, and the sermon is over an hour long and gives Rachel a headache.
Instead of going to the second service that afternoon, Rachel goes for a walk with Mr. Bruff.
When they get back, she looks thoughtful.
She doesn't eat any supper.
The next morning, Miss Clack goes into Rachel's bedroom with a cup of tea before breakfast.
Rachel seems to be lost in her own thoughts.
Miss Clack wants to know what Mr. Bruff said to her, and tries to steer the conversation in that direction.
Rachel won't say much about it, except that she's grateful to Mr. Bruff for giving her some news.
Miss Clack then says something about Rachel's engagement to Godfrey Ablewhite.
Rachel interrupts her, saying that she's not going to marry Godfrey.
Miss Clack is shocked, but Rachel won't explain.
She just says to wait and see.
Miss Clack goes out for a walk.
When she gets back, she meets Godfrey Ablewhite.
He seems very glad to see her, and seems like his old self.
Miss Clack asks if he's seen Rachel.
Yes, he's seen Rachel. And yes, she's broken off the engagement.
But he seems very calm about it and promises to explain.
