how to manipulate relationships—Earth's greatest discovery—to set up a system that would work. It paid off for us in the long run." 

 "So what's all that got to do with me?" Duke asked. He'd heard of the great science of Earth and her ability to manipulate all kinds of relationships before, spoken of in hush-hush terms when he was still in college. But he'd quit believing in fairy tales even before then. Now he was even sicker of Earth's self-justification. 

 Flannery frowned, and then shrugged. "It's no secret I need a good man on Throm, and you're the logical candidate, if I can pound some facts into your head.
