L'Affaire Tournesol
Like the previous volume, "Explorers on the Moon", "The Calculus Affair" was created with the aid of the Hergé's team of artists at Studios Hergé. The story reflected the Cold War tensions that Europe was experiencing during the 1950s, and introduced three recurring characters into the series: Jolyon Wagg, Cutts the Butcher, and Colonel Sponsz. Hergé continued "The Adventures of Tintin" with "The Red Sea Sharks", and the series as a whole became a defining part of the Franco-Belgian comics tradition. "The Calculus Affair" was critically well-received, with various commentators having described it as one of the best Tintin adventures. The story was adapted for both the 1957 Belvision animated series "Hergé's Adventures of Tintin", the 1991 Ellipse/Nelvana animated series "The Adventures of Tintin", and the 1992-3 BBC Radio 5 dramatisation of the "Adventures".
