The Calculus Affair

“For The Calculus Affair, I traveled for the first time, in order to sketch and take photos of the places where the action was going to take place.” –Hergé

An amazing invention from Professor Calculus starts to cause disasters at Marlinspike Hall: all the windows blow out, as well as most of the glass objects! Professor Calculus' new discovery is a source of envy and he is soon abducted. It’s now up to Tintin and Captain Haddock to rescue their friend and prevent his mysterious invention from being transformed into a fearsome weapon.
Tintin, perhaps one of the most famous cartoon heroes of all time, is as much a child of the 20th century as his creator, Georges Remi—aka Hergé (1907-1983). Tintin’s adventures, marked by his inquisitiveness, sense of mystery and witty humour, are deeply rooted in the events of that tumultuous era.
