The shadow of the supermutant, Tropnow, kidnaps Thora. Rhodan is not amused. With Pucky and Noir he goes into action. Actually, not much is going on. The traitors die without much resistance.
The only interesting thing in here is that there is some critique of Llloyd against PR. Maybe he should have handled things differently regarding the two guys. And Rhodan himself is not sure that he was right in denying them the bliss of eternal life.
