In the case of Mark Twain’s “Luck”, the one-word title actually has something to do with the story. The story leaves a lot of questions, though. A much-decorated military figure is being honored while a clergyman at the event explains to the narrator that the honoree is only where he is by sheer luck because he is actually a “fool”.
Who is the real “sham”? The acclaimed leader or the clergyman? And who does Twain consider the real “sham”? That’s the question I find intriguing but for which I find no real answer.
