There is a ship-captain called Jean-Luc Picard.
Yes, I know it's a perfectly ordinary French name so why wouldn't a guy in the 17th century be called like that but...
It's also one of those books with random French phrases in the dialogue. You know in a book set in France...I sort of assume that they speak French anyway so I do wonder what language I'm supposed to imagine when Richelieu calls Marie 'ma nièce'. Double-French? Klingon?
