never took anything that was not his due—not even if it lay abandoned and rotting. It was one of the differences between Glenn Tropile and the people he moved among. I've got it made, he exulted; it was what I needed to clinch my victory over her. He spoke: "I need you more than I need coffee, Gala." She looked up, troubled. "What would I do," he demanded, "if a beam fell on you one day while you were scrambling through the fancy groceries? How can you take such chances? Don't you know what you mean to me?"

Its appearance was known: constructed on a base line of some thirty-five yards, slaggy, midnight-blue in color. Almost nothing else about it was known—at least, to mankind. It was the only one of its kind on Earth, though men thought (without much sure knowledge) that there were more, perhaps many thousands more, like it
