I was recently re-reading one of my all time favourite murder mysteries, And then there were none, by Agatha Christie, and was amazed to find it just as intriguing as the very first time. I just can't get over how brilliantly written it is. Right from the opening chapter she is obfuscating the murderer and misleading the reader, but if you go back to it once you reach the end, all you can do is be astounded that you missed the clue that was presented in her careful wording.
After finishing the book, I downloaded the television drama that was available on Amazon video in 3 parts. I have noticed in previous versions that they changed the ending, and while there were some changes made, this one didn't shy away from the final death. I just wanted to take a moment, if you haven't read the book, to recommend it. It truly is murder mystery at it's best!
