The little doctor began to enumerate on his fingers. "The center of population has shifted to this vicinity, so the average American lives here in the Middle West. Population is also shifting from rural to urban, so the average man lives in a city of approximately this size. Determining average age, height, weight is simple with government data as complete as they are. Also racial background. You, Mr. Crowley, are predominately English, German and Irish, but have traces of two or three other nationalities."
Crowley was staring at him. "How in the devil did you know that?"
Ross said wearily, "We've gone to a lot of trouble."
Dr. Braun hustled on. "You've had the average amount of education, didn't quite finish high school. You make average wages working in a factory as a clerk. You spent some time in the army but never saw combat. You drink moderately, are married and have one child, which is average for your age. Your I.Q. is exactly average and you vote Democrat except occasionally when you switch over to Republican."
"Now wait a minute," Crowley protested. "You mean I'm the only man in this whole country that's like me? I mean, you mean I'm the average guy, right in the middle?"
Patricia O'Gara said impatiently. "You are the nearest thing to it, Mr. Crowley. Actually, possibly one of a hundred persons would have served our purpose."
"O.K.," Crowley interrupted, holding up a hand. "That gets us to the point. What's this here purpose? What's the big idea prying, like, into my affairs till you learned all this about me? And what's this stuff about me getting something out of it? Right now I'm between jobs."
The doctor pushed his battered horn-rims back on his nose with his forefinger. "Yes, of course," he said reasonably. "Now we get to the point. Mr. Crowley, how would you like to be invisible?"
The three of them looked at him. It seemed to be his turn.
