L'Or et le Sang is a comic book series by Fabien Nury (script), Merwan and Fabien Bedouel (drawing).
Calixte de Prampéand, a Parisian aristocrat and industrialist, never imagined he would meet a holibrist of the calibre of Léon Matilo, a Corsican from Marseilles trained in the methods of the Panier underworld. And vice versa!
