Neither of them said anything. The man in tweed seemed embarrassed. Mr. Kemper took a bite of the hot dog and chewed reflectively. After a while, he said, "I suppose I ought to recognize you, but I don't. Council of Science, no doubt." The man answered stiffly: "Ulbasar, of the First Science Council. Lord Kjem, you are under arrest." "You'd better use words; it's less liable to make anyone suspicious. You might have dressed a little more intelligently, too."
