 What is Dom Blessings's relationship to Dr. Mansard?
Trella feared she was in for trouble even before Motwick's head dropped forward on his arms in a drunken stupor. Perhaps she could call one of Motwick's friends; she had no one on Ganymede she could call a real friend herself. The dark man moved in on Trella again as Kregg overtook his quarry and swung a huge fist like a sledgehammer. 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. He followed Trella out the door of the Golden Satellite and fell in step beside her. “If Dr. Mansard succeeded in landing on Jupiter, why didn't anyone ever hear from him again?” she demanded.
