An 1878 novella (too long to be a short story, too short to be a novel) by Henry James -- half romantic comedy, half social commentary and mockery of rich, snobby Americans who tried to imitate rich, snobby Europeans. Available here. With all the misunderstandings, bad judgment and Daisy's clever wit, the scandal plays out like a typical romantic comedy. And then Daisy dies of Roman fever, and Winterbourne realizes too late that he was wrong about her, so he goes back to his older mistress in Geneva since it's too late for him to change. He has lived too long in foreign parts.
