Christie's most popular work by far, this tale of ten people on an island killed one by one really is quite gripping. It's so easy to absolutely tear through the book as the mystery continues to become more and more intriguing and tense. You can definitely see why it became such a popular formula to the point of being the foundation of the slasher film genre and many mysteries since, including works released to this day. My only complaints are that it's a little short and the reveal is actually not as satisfying as I would've hoped but it's still worth a read for any mystery fan.
