It is a real book, but it wasn't something I read. My agent had it on hand and read from it to give me some ideas for a story. I believe the book was called something like, "Weird Stories of New York," or something like that. So sorry I can't be more specific, but he can't remember the name of the book either. Still, I'm sure if you're looking for books on haunted places, there're some awesome ones out there! Good luck!
