Landmaus und Stadtmaus auf Reisen

Cousin Sophie has invited Emily and Alexander to a very special event: they can be there when the great inventor Marconi receives a radio message for the first time. The two travel all the way to Newfoundland for the occasion. There is an antenna here that is supposed to receive the radio message from England. However, strange things happen there. Someone tries to prevent the experiment at the last moment. Once again a case for our clever amateur detectives.
