I read this book for the first time, almost 16 years back. It was part of those Reader's Digest compiled editions, which has three-four famous books across different genres. Since then, I think I must have consumed this story in all forms available-the book, the movie, the tele series, the audio play, audio book and still on a lookout for a version/medium that I haven't come across.
YES. THAT IS HOW MUCH I LOVE THE SCARLET PIMPERNEL :)

It was infact this book that introduced me to historical romances (a time when I acutely loathed mushy stuff. Haah! lot did I know what I was missing!)

This book gets all the points imho for being an adventure sort of swashbuckling (sans any pirates though) story set during the Reign of Terror during the French Revolution.
It definitely tickled my uninitiated palate for romances and need for a happy ending with the end justifying the means.
So definitely 5+ stars to my all-time favorite Classics.
