as any material in existence and its insulating qualities couldn't be matched. In the spotless control cabin he found that the instruments were fully modern. The cabin was globular; gyroscopes kept the gravity—if any—under its floor. A glance into other compartments brought a whistle to his lips—the Chicago was crammed with fuel and food. Gail Melvin must have prepared this as a permanent home. Two tiny sections were the sleeping quarters of Gail and George Melvin. He poked around them until a feeling of guilt made him stop. He sank into a spongy, bolted-down chair, damning his new-found ethics. He'd straighten out a few things when that female showed up. She didn't seem surprised to see him.

"They questioned George with a new type of lie detector—Skolssolky or some such name. I wasn't supposed to know—" Barnard's eyebrows went up. "The police questioned George? Somebody must have found out!" Gail dropped her coat over the back of another chair and sat on the chair. She was pale and her eyes were haggard. "When I found the police had picked him up," she said, "I took an espine pill and became en rapport with him."
