The Gumdrop ghost

Now you see her, now you don't... She does headstands, she does cartwheels, she can even do a split! Lizzie Benson gives such an amazing performance in a River Heights talent show that she wins a shopping spree at Tremendous Toys. But is Lizzie for real? She looks an awful lot like the actress in a very old movie poster whose name was Elizabeth Benson. And Lizzie says she lives at 10 Tide Street -- a haunted house. Nancy's friends are convinced that Lizzie is a ghost. Nancy says she'll prove them wrong -- but does she have a ghost of a chance?.
