In "The Storyteller", by Saki, the theme that is best supported by the story the bachelor tells is <em>Pride comes before a fall.</em>
There are three children with their aunt on a train. They are boisterous. She tries to entertain them with a story about a good girl to whom good things happen. As the children are bored by it the bachelor, who travels in the same train tells them a story about a girl who is "horribly good". She has a lot of medals pinned in her dress and a wolf finds her because her medals make noise. Excessive pride comes before something bad makes you realize that you are not so good.
