Well, we don’t know much about this character, as she doesn’t appear so often to memorize her. Grace Poole is chubby, middle-aged, red-haired dressmaker who works as a servant at Thornfield Hall. Also, she is secretly the nursemaid and correctional officer for the insane Bertha Mason. Jane keeps thinking that Grace is responsible for the strange laugh on the third floor, the attempt to burn Rochester alive, and other strange and creepy nighttime things. Once, she failed much; Bertha escaped and burned the house making severe injuries to Mr. Rochester.
