Strange things are happening in the evening at the mansion. Glass things break without any apparent reason. The Professor, somewhat apathetic to the whole series of events, leaves the following day to attend a conference on nuclear physics in Geneva. Foreign powers get wind of the Professor's work and send their agents to investigate.
