Agatha Christie, you've done it again.
This is my eighth Agatha Christie novel, and I still haven't been able to predict the ending.
What I think lifts this book above the others is how there are morals for each of the murderers' original crimes.
For example...
General Macarthur: takes revenge Send's his wife's lover unnecessarily into battle where he gets killed
Anthony Marston: little regard for human life Runs over two kids and has no regrets
Mr. & Mrs. Rogers: neglect Neglect to save their employer's life because they gain much money as inheritence
Once again, this book just has me amazed. She even threw in some wordplay! U. N. Owen (a.k.a. Unknown) invited them to the island
Definitely a five stars (I would do six, but there is no option!)
