I always really enjoyed Agatha Christie's books and her skill to write mystery. I have read many of her books, but I really liked the first one I read, And Then There Were None, formerly known as Ten Little Indians. Just recently, I read Curtain: Poirot's Last Case, which was a good book too, but the ending is quite sad, but it's still a good book. Another one of her books I liked was The Seven Dials Mystery, which was quite a twist at the end. Most of her books that I have read, I have forgotten, like Sleeping Murder. I personally think that her most boring book so far must be The Hound Of Death, which has twelve different stories, and most of them are boring and confusing, but some were good.
