A spaceship claiming to be from Earth requests a landing beam, but John doesn't trust them and uses a shield to keep them away. A good thing, too, because the crew is four criminals who robbed a deuterium bank and are now fleeing the Space Patrol. They chanced across Zumdish, who has quit the Celestial Department Store and now operates a tour agency. Using this cover and playing on Smith's greed, they find a way to land. And they decide this planet will make a nice hiding place, once they get rid of the people who are already there.
