The Heritage of The Devil T01-T04 Complete

A good historical mystery/action comic in the tradition of the Da Vinci's Code.
Constant is trying to find the love of his life, who disappeared four years ago. A priest carries a secret that the Nazis and the malevolent singer Emma Clave both covet. A painting holds more clues to a great power, and a thief is sent to destroy it. And it all points to Rennes-le-Château.
