Best part of story, including ending:
This story is a great update on the classic Nancy Drew mystery stories from the books.
Best scene in story:
I like the scene when Nancy finds the secret passageway in the big mansion, because every big mansion needs to have secret passageways to be interesting.
Opinion about the main character:
Nancy tries her best to give up sleuthing at the request of her father, but finds she is not able to give it up. Her reasoning is sweet because she is really trying to help the other young woman named Jane discover the truth abour her birth mother.
