A number of people applauded out of habit ... probably lecture fans or semi-pro TV studio audiences. The rest, including Clocker, waited as an aging man in a white lab smock, heavy-rimmed eyeglasses and smooth pink cheeks, looking like a benevolent doctor in a mouthwash ad, stood up and faced the crowd. He put his hands behind his back, rocked on his toes a few times, and smiled benevolently.

"Thank you, Mr. Calhoun," he said to the bearded man who was seating himself on a marble bench. "Friends—and I trust you will soon regard us as your friends—I know you are puzzled at all this." He waved a white hand at the buildings around them. "Let me explain. You have been chosen—yes, carefully screened and selected—to help us in undoubtedly the greatest cause of all history. I can see that you are asking yourselves why you were selected and what this cause is. I shall describe it briefly. You'll learn more about it as we work together in this vast and noble experiment."

The woman in the flowered housecoat looked enormously flattered. The little tailor was nodding to show he understood the points covered thus far. Glancing at the rest of the crowd, Crocker realized that he was the only one who had this speech pegged. It was a pitch. These men were out for something.

He wished Doc Hawkins and Oil Pocket were there. Doc doubtless would have searched his unconscious for symbols of childhood traumas to explain the whole thing; he would never have accepted it as some kind of reality. Oil Pocket, on the other hand, would somehow have tried to equate the substantial Mr. Calhoun and Dr. Harding with tribal spirits. Of the two, Clocker felt that Oil Pocket would have been closer.

Or maybe he was in his own corner of psychosis, while Oil Pocket would have been in another, more suited to Indians. Spirits or figments? Whatever they were, they looked as real as anybody he'd ever known, but perhaps that was the naturalness of the supernatural or the logic of insanity.

Clocker shivered, aware that he had to wait for the answer. The one thing he did know, as an authority on cons, was that this had the smell of one, supernatural or otherwise. He watched and listened like a detective shadowing an escape artist.

"This may be something of a shock," Dr. Harding continued with a humorous, sympathetic smile. "I hope it will not be for long. Let me state it in its simplest terms. You know that there are billions of stars in the Universe, and that stars have planets as naturally as cats have kittens. A good many of these planets are inhabited. Some life-forms are intelligent, very much so, while others are not. In almost all instances, the dominant form of life is quite different from—yours."

Unable to see the direction of the con, Clocker felt irritated.

"Why do I say yours, not ours?" asked Dr. Harding. "Because, dear friends, Mr. Calhoun and I are not of your planet or solar system. No commotion, please!" he urged, raising his hands as the crowd stirred bewilderedly. "Our names are not Calhoun and Harding; we adopted those because our own are so alien that you would be unable to pronounce them. We are not formed as you see us, but this is how we might look if we were human beings, which, of course, we are not. Our true appearance seems to be—ah—rather confusing to human eyes."
