This book is great for a few reasons, namely that it focuses more on someone OTHER than the Pimpernel (don't get me wrong -he's cool, too, but it's not really his story).
This time, SP is only a help in a story where Juliette Marny (the heroine) is determined to right a wrong done to her brother (alas, deceased). When the opportunity comes, she takes it, only to find that she has fallen for the man she swore to bring down. So does it work out?
It all takes a little thinking, some tender memories and lots of pluck from Sir Percy, our heroine and her beloved, with Chauvelin and the revolutionary tribunal on their heels to make a great read.
