The book. Also known as "Ten Little Indians". By Agathie Christie.
I love this book. I haven't seen either movies, but the book is sooooo good. It's one of the best classics ever (usually they're boring). It is about 10 people stuck in a mansion on an island and one of them is a murderer, picking them off one by one. It is so hard to pick out who the murderer is until it's down to two and the murderer kills the other guy. You have to read this. If you like murder mysteries, read it. If not, read it! I hate murder mysteries normal, but this one was so owesome!
Anyone else like this book?
