looking for information 

Hello. Does anyone know the name of the book or the author about a boy who was rescued from the moors in England by a man dressed up as a convicted criminal to go live with his great aunt who is in a wheel chair and only wears a wedding dress and in a locked room of the house sits a wedding cake-the whole room is set up for a wedding party but is covered in cob webs because it happened along time ago. Basically the aunt's wedding never happened. This book is centered around the 1800's in England. (I think) Any info leading me in the right direction would help, trying to find the book for a friend. I believe it was made into a movie/play Please email me at mgiddley2434@charter.net
Thank you!
