I started this book the day I got it, late in the afternoon. I was halfway done by bed time. I didn't get back to it until the afternoon the next day. I finished the book by 9:00 pm.I didn't know who mastermind was until the very last sentence of the book! I was blown away. I usually guess the end long before I finish a book, but this book was spellbinding until the last sentence.I recommend this book highly, you'll be turning the pages very quickly. I also bet you won't guess who did it either. ENJOY!
