The Spirit of Adventure (L’esprit d’aventure) by Nob
From the Journal de Spirou #3914, the 75th anniversary special (2013).
“I tried not to get lost in parody. I’ve always loved the feel of Champignac. The idea was that a weekend with the Count would be like a weekend with your own grandparents! And I would love to read the next part of this story – which stops just when the adventure really begins!” Nob
