Tintin: The Calculus Affair
Strange things are happening at Marlinspike Hall. Windows, glass, mirrors and vases break without warning. Professor Calculus, apathetic to the events, leaves for a conference on nuclear physics in Geneva. Foreign powers get wind of Calculus work and send an agent to investigate. Sensing danger, Tintin, Snowy, Captain Haddock and the Thompson detectives go to his aid, but what exactly will they find in Switzerland?
