 What is Trella's relationship to Dom Blessing?
This e-text was produced from Amazing Science Fiction Stories March 1959. Trella feared she was in for trouble even before Motwick's head dropped forward on his arms in a drunken stupor. 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. Perhaps she could call one of Motwick's friends; she had no one on Ganymede she could call a real friend herself. Trella swung with her whole body, and slapped him so hard he nearly fell from his chair. There were only two other people in the Golden Satellite: the fat, mustached bartender and a short, square-built man at the bar. Her protector was obviously unwilling, but the dark man, faced with his massiveness, took no chances. Evading her attempts to stay behind him, the squat man began to move down the bar away from the approaching Kregg. The dark man moved in on Trella again as Kregg overtook his quarry and swung a huge fist like a sledgehammer. Exactly what happened, Trella wasn't sure. She had the impression that Kregg's fist connected squarely with the short man's chin before he dodged to one side in a movement so fast it was a blur. But that couldn't have been, because the short man wasn't moved by that blow that would have felled a steer, and Kregg roared in pain, grabbing his injured fist. It smashed on Kregg's head, splashing the floor with liquor, and Kregg sank stunned to his knees. The dark man, who had grabbed Trella's arm, released her and ran for the door. Moving agilely around the end of the bar, the bartender stood over Kregg, holding the jagged-edged bottleneck in his hand menacingly. Trella ran to the unconscious Motwick's side. He followed Trella out the door of the Golden Satellite and fell in step beside her. The transparent dome of Jupiter's View was faintly visible in the reflected night lights of the colonial city, but the lights were overwhelmed by the giant, vari-colored disc of Jupiter itself, riding high in the sky. “I'm Trella Nuspar,” she said, favoring him with a green-eyed glance. “He and my mother lived on Jupiter until the oxygen equipment wore out at last. “If Dr. Mansard succeeded in landing on Jupiter, why didn't anyone ever hear from him again?” she demanded.
