Il y a un sorcier à Champignac
André Franquin
 In There is a Sorcerer in Champignac, Spirou and Fantasio go on a bicycle camping trip to the country and end up near the village of Champignac-en-Cambrousse. They meet its pompous mayor and rustic inhabitants, and an aloof local landowner, the Count of Champignac. Strange phenomena are affecting farm and wild animals, and the frightened villagers blame a gypsy who is passing through. Spirou and Fantasio, however, discover that the real culprit is the Count, deeply involved in creating strange concoctions from mushrooms, and they rescue the vagabond from a lynch mob. Later, the Count creates a drug that within a limited time will endow superhuman strength, which a gangster steals to create mayhem.
