L'abbaye truquée
 Spirou, Fantasio and their guest Itoh Kata are visited by Charles Atan and his henchman Renaldo, members of The Triangle, who abduct the Japanese magician as a means of forcing his friends to join their organisation. The trail leads them to an old abbey located in an abandoned village. There, Spip, their pet squirrel, also disappears. During this time, Kata's kidnappers are unable to keep him captive very long due to his conjuring tricks, no more than Spip who rejoins Spirou and Fantasio. When Spirou and Fantasio finally find Kata, he has just locked up all the men of the Triangle in a cell, with the exception of their leader, Charles Atan, and his assistant Renaldo. Continuing their search, they prevent the self-destruction of the abbey and capture Atan. But Renaldo frees his boss and the two gangsters flee.
