It was hotter when he reached the main enclosure, but still cool by his standards. At a refreshment stand he ordered a hot dog with mustard. As he waited, leaning against the counter, he saw the man in the tweed jacket among a group of people walking toward the elephant yard. He paid for the hot dog, picked it up, and walked along the path, keeping the jacket in sight.
The man in tweed went by the elephants, past the giraffes and the zebras, then around the south wing of the building. Up the walk toward the aviary he went, with Kemper not too far behind. At the top of the hill the man stopped in front of the aviary. It was a wide enclosure fenced by bars thirty feet high. In the larger section were the myriad ducks, cranes, gulls and other harmless birds; walled off from these were eagles, vultures, and condors squatting on carved balconies. From the hilltop there was a fine view of the zoo grounds below. The man in the tweed jacket turned, apparently to look down the hill, but instead looked squarely at Mr. Kemper standing a few feet away.
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."
Ulbasar ran his hand over his jacket lapels. "But it's cold. How do you stand it in that light shirt?"
"Very simple; I'm wearing long underwear."
"Well, you've obviously been here much longer than I have."
"Yes," said Kemper. "I've been here quite a while."
