He plans to take a flirtatious girl to Paris as his mistress, but to his astonishment the girl's sister (the sensible and stubborn Mary) fools him into taking her place. Mary is a wonderful heroine--she full on shoots the hero at one point--and her affection for him even made me like Vidal. And it must be admitted that Vidal is far, far warmer and less creepy than his elegant father Avon. I enjoyed this book rather more than These Old Shades, despite the lack of cross-dressing, because I found the characters and their relationship to each other so much less icky.
