Now, this is "the perfect crime".

This thrilling murder mystery, about 10 strangers in an island being killed off one by one according to a nursery song, is a gripping tale that gets you off guard in the best way possible.

You are not a true mystery/crime/thriller fan if you haven't read this book yet. This is mystery at its best. There is no detective to solve the crime for us. There is supposedly not even a murderer and at the end, there remain nobody, not even a single soul to explain what happens. But somehow this genius of a woman makes everything make perfect sense.

Not only that but it also raises the old question of what is justice, who decides it and who has the right to execute it? Is it ethical to kill someone whose actions were unintentional but never the less resulted in the death of someone?
 
And that's why I love Agatha Christie and devour her books. She doesn't just focus on the "exciting" parts that make your heart beat, she also adds in her little touch of morality and psychology. 
 
If you've decided to give this book a go, do yourself a favour and double the pleasure of it by listening to the audiobook narrated by the MAGNIFICENT Dan Stevens. He will NOT disappoint you
