Book 25 of 52: And Then There Were None by Agatha Christie.
This was my first Agatha Christie novel, and it did not disappoint. This twisty whodunnit reminds me of the game Clue. 10 individuals are invited onto a private island by an unknown guest. Each one has a secret. As night falls, one by one they are murdered, leaving everyone to wonder: is the murderer among us?
