The Haunted Doll's House

Amy's mother dies one day, rather suspiciously. Was it the imaginary ghosts? Or is Amy really crazy?
We were told to wrote a story about a doll house. It could be anything as long as it was to do with a dolls house in some way. This was my story. Not the most riveting or exciting, but I aimed to be more thought provoking if you could get to the end.
NOTE:-I have no idea whether it's a dolls house or a doll house so just deals with it!
