Description
Odd things are occurring in the evening at Marlinspike Hall. Windows,
glass, mirrors and vases break without any obvious cause. Professor
Calculus, somewhat apathetic to the entire series of incidents, leaves
the next day to go to a meeting on nuclear physics in Geneva.
International powers get wind of Calculus’ work and send one of their
agents to check out. Detecting danger, Tintin, Snowy, Captain Haddock
and the detectives Thomson and Thompson go to Professor Calculus’ help . |
