I don't remember when exactly I read this book. I'm pretty sure it was during 6th grade because that's when I used to read Nancy Drew. It doesn't matter when I have read it because to this day, I call this book one of my favorites. Whenever someone asks me what my favorite book is, I reply with this one (even though it isn't my #1; I don't have a #1.) This book is basically about people's minds, creepy professors, and hypnosis !!! The hypnosis part of this book was so great I immediately wanted to learn how to hypnotize people. A mystery and suspense filled book. Not like regular Nancy Drew series, innocent and young. The Nancy Drew: Files are more hardcore than the younger series's. More murder, more danger, and a lot more suspense. My favorite Nancy Drew book among the hundreds I have read. (Yeah, I have read almost all of the books in all of the different Nancy Drew series. Even the little kid's ones. )GREAT BOOK!!
