If there is one character archetype I love the most, it is the sort of noble thief with the charm, wit, and panache to make you go "he may be a criminal, but he's damn fine criminal." I think what makes Lupin stand out amongst the classic antiheroes is his sense of giving due credit and possessing a bit of heart. He's no Robin Hood, he doesn't steal out of a need to redistribute wealth to those less fortunate, at least, not always, but there are moments when he forgoes theft entirely to appease those he cares for. His moral code is fascinating, always adjusting itself to the situation. 

Some of the stories' logic and how they unravel is a bit confusing at times, though that may be me adjusting to that older sort of vernacular and sentence structure or simply a bad translation Still, there wasn't a particular story I disliked and, even if I wasn't entirely entertained by the events, Lupin's inventiveness and personality are always the highlight of any tale he's in. Some of them even tend to be pretty comical at times, whether it's the master thief himself being the victim of a robbery or his crossover with Sherlock Holmes being nothing more than a passing conversation. 

Though the stories are simple, surface level stuff, the real draw is Lupin himself, with his unshakable confidence and ability to pull the wool over anyone's eyes.
