For today's Tuesday Paris reading rec, a book I reviewed for the New York Times more than a decade ago, but I've enjoyed seeing on my own shelves ever since. The Mistress is a much better title than The Gastroenterologist, though the latter is much more accurate. And I'm standing by the line, "''Gut-wrenching" ... has never described a scene so well as it does a Nazi's gurgling death by the most exquisitely French means." Though this isn't really a mystery novel, if you're a fan of clever twists, you'll find a memorable one here.
