|I recently finished listening to the Librivox recording of The Extraordinary Adventures of Arsène Lupin, Gentleman-Burglar. Librivox make it available as a free podcast, but I notice the book is also available from Amazon.|
This is Maurice Leblanc's classic. The Sherlock Holmes/Hercule Poirot who took the other path in life!
I first encountered the character in the Japanese anime Lupin III by Kazuhiko Kato.
