Just thought of something
How come no one's written a mystery series set in the world of competitive figure skating yet? (At least I don't think they have.) I would think the title Death Spiral would be a slam-dunk. You could call it the Gold Medal Mysteries (tho' that does sound a little bit like a baking mystery). Maybe the Triple Axel Mysteries? Sharp Blades Mysteries?
No, I'm not going to write it. Well, maybe in some amorphous future when I have copious amounts of free time.
