This book truly scared me. Read this book alone in a dimly lit room. You can feel the London fog and the vacant streets. The accounts given by Stevenson of Hyde's behavior aren't quite as chilling as when you hear of it from another character in the story especially when the accounts are given to Jekyll who knows the true identity of the madman. Not a second is wasted in this book except maybe the last chapter which felt a bit unnecessary. The book is short and to the point and develops at such a fast pace you can hardly catch your breath. You won't even want to take a bathroom break from this read. I'm not much for re-reading books but this one I will certainly read again someday.
