Hot Money is the inheritance one. It’s one of my favorites, although I’m not sure why. There’s no romance at all, and although our hero does get a bit roughed up a bit, he doesn’t show the kind of perseverance through physical pain that typifies the Dick Francis hero. It does have a very good mystery-novel trick, where the titular money is essentially a McGuffin. Everybody assumes all along that the murderer must be after the money, when it turns out to be something else entirely. And, of course, it’s the troubles of foolish rich people, which is always good for an escape.
Is it possible that Hot Money is out of print in the US? Neither Penguin nor Random House have a web page for it. I don’t really know what the rights situation is with his back catalogue, but I would figure that a publisher could turn a profit on keeping just about any Dick Francis novel in print. Ah, well.
