Ooo Lupin
If you havent heard about Lupin the third, he is rather like james bond but less cool and more a perv.
My french is not good enough to have read much Arsène Lupin, but I like this idea.
It could be a lot of gun to do the nobel thiefs, gentlewomen and gentlemen working together to steal grand jewels (very oceans 11), or some working to steal it and some working against it.
