Arsene Lupin versus Herlock Sholmes 

Le Blanc’s creation, gentleman thief Arsene Lupin, is everything you would expect from a French aristocrat — witty, charming, brilliant, sly . . . and possibly the greatest thief in the world. In this classic tale, Lupin comes up against the only man who may be able to stop him . . . no less than the great British gentleman-detective Herlock Sholmes! Who will emerge triumphant? (Amazon)
