 How does Pop feel about Sattell?
There is nothing like it on Earth, of course. Sattell got the shakes when he thought of Pop, and Pop rather probably knew it. He'd started to follow Sattell knowing what had happened to his wife and children, but it was hearsay only. When Sattell fled to another continent, Pop followed because he had some distinct memories of his wife—and the way he'd felt about her—and some fugitive mental images of his children. When Sattell frenziedly tried to deny knowledge of the murder in Tangier, Pop had come to remember both his children and some of the happiness of his married life. The sun rose very, very slowly in what by convention was called the east.
