Trella feared she was in for trouble even before Motwick's head dropped forward on his arms in a drunken stupor. Trella had not wanted to come to the Golden Satellite. It was a squalid saloon in the rougher section of Jupiter's View, the terrestrial dome-colony on Ganymede. A woman could not possibly make her way through these streets alone to the better section of town, especially one clad in a silvery evening dress.

I was born and brought up there, and I was finally able to build a small rocket with a powerful enough drive to clear the planet.” “If Dr. Mansard succeeded in landing on Jupiter, why didn't anyone ever hear from him again?” she demanded. 53 “You wear Motwick on your shoulder like a scarf.
