was very tall and dignified and wore formal clothes and had a white beard parted in the center.

"Please feel at ease," he said in a big, deep, soothing voice, like a radio announcer for a symphony broadcast. "You are not in any danger. No harm will come to you."

"You sure we ain't dead, sweetie?" the woman in the flowered housecoat asked Clocker. "Isn't that—"

"No," said Clocker. "He'd have a halo, wouldn't he?"

"Yeah, I guess so," she agreed doubtfully.

The white-bearded man went on, "If you will listen carefully to this orientation lecture, you will know where you are and why. May I introduce Gerald W. Harding? Dr. Harding is in charge of this reception center. Ladies and gentlemen, Dr. Harding."

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."

Nuts, Clocker thought irreverently. Get to the point.

"I don't think this is the time for detailed explanations," Dr. Harding hurried on before there were any questions. "We are friendly, even altruistic inhabitants of a planet 10,000 light-years from Earth. Quite a distance, you are thinking; how did we get here? The truth is that we are not 'here' and neither are you. 'Here' is a projection of thought, a hypothetical point in space, a place that exists only by mental force. Our physical appearances and yours are telepathic representations. Actually, our bodies are on our own respective planets."

"Very confusing," complained a man who looked like a banker. "Do you have any idea of what he's trying to tell us?"

"Not yet," Clocker replied with patient cynicism. "He'll give us the convincer after the buildup."

The man who looked like a banker stared sharply at Clocker and moved away. Clocker shrugged. He was more concerned with why he didn't feel tired or bored just standing there and listening. There was not even an overpowering sense of urgency and annoyance, although he wanted to find Zelda and this lecture was keeping him from looking for her. It was as if his emotions were somehow being reduced in intensity. They existed, but lacked the strength they should have had.

So he stood almost patiently and listened to Dr. Harding say, "Our civilization is considerably older than yours. For many of your centuries, we have explored the Universe, both physically and telepathically. During this exploration, we discovered your planet. We tried to establish communication, but there were grave difficulties. It was the time of your Dark Ages, and I'm sorry to report that those people we made contact with were generally burned at the stake." He shook his head regretfully. "Although your civilization has made many advances in some ways, communication is still hampered—as much by false knowledge as by real ignorance. You'll see in a moment why it is very unfortunate."

"Here it comes," Clocker said to those around him. "He's getting ready finally to slip us the sting."

The woman in the housecoat looked indignant. "The nerve of a crumb like you making a crack about such a fine, decent gentleman!"

"A blind man could see he's sincere," argued the tailor. "Just think of it—me, in a big experiment! Will Molly be surprised when she finds out!"

"She won't find out and I'll bet she's surprised right now," Clocker assured him.

"The human body is an unbelievably complicated organism," Dr. Harding was saying. The statement halted the private discussion and seemed to please his listeners for some reason. "We learned that when we tried to assume control of individuals for the purpose of communication. Billions of neural relays, thousands of unvolitional functions—it is no exaggeration to compare our efforts with those of a monkey in a power plant. At our direction, for example, several writers produced books that were fearfully garbled. Our attempts with artists were no more successful. The static of interstellar space was partly responsible, but mostly it was the fact that we simply couldn't work our way through the maze that is the human mind and body."

The crowd was sympathetic. Clocker was neither weary nor bored, merely longing for Zelda and, as a student of grifts, dimly irritated. Why hold back when the chumps were set up?

"I don't want to make a long story of our problems," smiled Dr. Harding. "If we could visit your planet in person, there would be no difficulty. But 10,000 light-years is an impossible barrier to all except thought waves, which, of course, travel at infinite speed. And this, as I said before, is very unfortunate, because the human race is doomed."

The tailor stiffened. "Doomed? Molly? My kids? All my customers?"

"Your customers?" yelped the woman in the housecoat. "How
