Nancy Drew & The Hardy Boys: The Lady in Grey and The Man in Red

Well, to start off I am a big fan of Nancy Drew and The Hardy Boys (eventhough I only read the Nancy Drew series). I watched this one episode of Nancy Drew and The Hardy Boys in 1 mystery- Nancy Drew and The Hardy Boys meet Dracula, and I LOVED it. So here I'm making a fanfic both series in 1. Enjoy!
It all started with a nice, welcoming conversation between the old friends- Nancy Drew, Bess Marvin, George Fayne and Frank and Joe Hardy. As they were chatting, Nancy saw a little boy and a girl, holding a woman's hand, running down the lane. They told her that they were chased by ghosts, a woman in grey and a man in red. Will Nancy and her gang get to solve this mystery? Read the book to find out!
