Ha! Same here.
I think i read The Mystery of Lilac Inn....or maybe I bought it then didn't read it! Did you finish reading it?
Just so you know, the Hardy Boys, I think, are a lot like Nancy Drew, but they're boys.
The Bobsey Twins I think you might enjoy.....I think I read one of then a while ago.
You're welcome! I'm working on a few fantasy/fiction stories, too!
