Four really good short stories. The one I think of most often is "Chawdron", one of the best examples I have ever seen of how to use an unreliable narrator.
The framing device is that a charming, witty, extremely cynical friend is telling the story after breakfast at a country house. With evident disgust, he describes how a wealthy industrialist, Chawdron, falls for a young woman, Maggie Spindell. Well, "falls" is maybe the wrong word. It's not clear that anything sexual happens. He becomes enamored of her soul, and finds her a remarkable, unique person, who opens his eyes to things he things he has never experienced before. The narrator encourages us to groan along with him at Chawdron's naive sentimentality, and the transparent subterfuges that Maggie uses to manipulate him. He knows she is just a cheap con-artist playing her mark, and also that she is terrified he will unmask her.
As the scene at the breakfast table progresses, it however becomes clear that the narrator is not a very nice person either, and that he may well have his own reasons for presenting the story the way he does. Some details don't quite ring true. After a while, you start to wonder if Chawdron could be right. Perhaps Maggie really is an exceptional person, and the narrator, eaten up with envy, is refusing to admit what he actually knows very well.
Huxley succeeds perfectly at keeping both views of the story plausible; at the end, I was uncertain which one to believe. It's a great technical achievement, and nonstop entertaining.
