Great Expectations: Charles Dickens' fiction on mystery and adventure

One day a legal counselor named Jaggers shows up with odd news: a mysterious sponsor has given Pip an enormous fortune, and Pip should come to London quickly to start his schooling as a man of his word. Pip cheerfully accepts that his past trusts have worked out-that Miss Havisham is his mysterious advocate and that the elderly person means for him to wed Estella.
