In this chapter, the author tells us how Mary Lennox arrived at Misselthwaite Manor, her uncle’s house.
She arrived there at night, so she couldn’t release what is a moor. Mrs. Medlock told her that her uncle, Mr. Archibald Craven, didn’t want to see the girl. She wasn’t surprised: nobody ever wanted to see her. Mary was told that she couldn’t go out of her room. Never. Ever.
