In Agatha Christie’s classic mystery And Then There Were None, ten strangers are summoned to a secluded island home, each believing for different reasons. When no host appears, they find themselves accused of murder. One by one they are forced to confront their past, and one by one they begin to die.
And Then There Were None is incredibly successful. I kept telling myself that I could figure it all out, and sure enough at the end– I was completely clueless. It seems like a good mystery is one in which you can’t figure out who-did-it, but when all is revealed the answer seems absolutely obvious.
