On his way home from his meeting with Professor Mannfeldt, Helius is mugged by henchmen of the gang. They steal the research that Professor Mannfeldt had entrusted to Helius, and also burgle Helius's home, taking other valuable material. Turner then presents Helius with an ultimatum: the gang know he is planning a voyage to the Moon; either he includes them in the project, or they will sabotage it and destroy his rocket, which is named "Friede". Reluctantly, Helius agrees to their terms.
