And Then There Were None

The title of "world's bestselling mystery" belongs to the classic And Then There Were None, by Agatha Christie, the queen of crime. The story starts with the account of how ten people came to an island for various reasons. They soon find out they are each accused of a murder that cannot be proved and that they are trapped on the island. The only clues as to what is going on are a record accusing them and an old nursery rhyme known as the Ten Little Indians.

One by one, people are killed in perfect accordance to the nursery rhyme. A thorough search of the island clearly points out that one of them must be the murderer and planner of this scheme, but it is impossible to prove who it is. As they dwindle in number, life on the island becomes full of terror, suspicion, and alertness as each fights for his life.

This book is amazing. Just when the reader thinks he has figured out who the murderer is, something happens that throws the whole theory off. Even as the last of the ten dies, he doesn't really know who the murderer is. If it weren't for a revelation in the epilogue, we would have an unsolvable mystery.
