The beginning of a well known book has been encrypted below. Each letter of the alphabet has been replaced by another using a simple substitution technique. For example, A may always be represented by G, etc. Can you name the book?

The piece of text is from the original Great Expectations , by Charles Dickens and should read:
"I am instructed to communicate to him," said Mr. Jaggers, throwing his finger at me sideways, "that he will come into a handsome property. Further, that it is the desire of the present possessor of that property, that he be immediately removed from his present sphere of life and from this place, and be brought up as a gentleman - in a word, as a young fellow of great expectations."
