I was so blessed to receive an electronic copy of this new release edition.  The final chapter is sealed so you have to try and solve the clues to find out whodunit. 

I love to try and solve the mystery before I reach the end of a book but this one was so cleverly plotted I didn't get it right.  Agatha Christie is the Queen of crime and this is an absolute masterpiece.  

Thank you Harper Fiction and Netgalley for providing the ARC
