This has to be the best murder mystery I've ever read. Agatha Christie has written a perfect mix of suspense, action, and character development. And Then There Were None is literally a page turner, once you start you can't stop! The conclusion was also so clever I doubt that anyone who's ever read this has actually figured it out. 
 I also love the way she ties in the 10 Little Soldier Boys rhyme. I kept referring back to it many times as I was reading. It serves as a sort of timeline to the story but don't worry, it doesn't give anything away. 
 I think more authors should take note of Agatha Christie. This novel came in at less than 260 pages and it packed more of a punch than any 500+ page book I've read recently. I think some authors feel like in order for a book to be "meaty" it has to be long. Agatha Christie proves in And Then There Was None that it doesn't have to be that way. Tell us a story, give us what we need to know, don't hide the plot in drawn out paragraphs and tired plot devices. It's amazing how well I felt I knew these characters by the end; there's other books that are twice the length that I finish and think "Wow did that actually go anywhere?" Sad but true (end rant). 
 I intend to pick up more Agatha Christie in the future, well worth the time!
