Donald Alford, research physicist, came across the POSAT ad tucked at the bottom of a column in _The Bulletin of Physical Research_. He was engrossed in the latest paper by Dr. Crandon, a man whom he admired from the point of view of both a former student and a fellow research worker. Consequently, he was one of the many who passed over the POSAT ad with the disregard accorded to any common object. He read with interest to the end of the article before he realized that some component of the advertisement had been noted by a region of his brain just beyond consciousness. It teased at him like a tickle that couldn't be scratched until he turned back to the page. It was the symbol or emblem of POSAT, he realized, that had caught his attention. The perpendicularly crossed ellipses centered with a small black circle might almost be a conventionalized version of the Bohr atom of helium. He smiled with mild skepticism as he read through the printed matter that accompanied it. "I wonder what their racket is," he mused. Then, because his typewriter was conveniently at hand, he carefully tore out the coupon and inserted it in the machine. The spacing of the typewriter didn't fit the dotted lines on the coupon, of course, but he didn't bother to correct it. He addressed an envelope, laid it with other mail to be posted, and promptly forgot all about it. Since he was a methodical man, it was entrusted to the U.S. mail early the next morning, together with his other letters. Three identical forms accompanied the booklet which POSAT sent in response to the three inquiries. The booklet gave no more information than had the original advertisement, but with considerable more volubility. It promised the recipient the secrets of the Cosmos and the key that would unlock the hidden knowledge within himself--if he would merely fill out the enclosed form. Bill Evans, the unemployed pharmacist, let the paper lie unanswered for several days. To be quite honest, he was disappointed. Although he had mentally disclaimed all belief in anything that POSAT might offer, he had watched the return mails with anticipation. His own resources were almost at an end, and he had reached the point where intervention by something supernatural, or at least superhuman, seemed the only hope. He had hoped, unreasonably, that POSAT had an answer. But time lay heavily upon him, and he used it one evening to write the requested information--about his employment (ha!), his religious beliefs, his reason for inquiring about POSAT, his financial situation. Without quite knowing that he did so, he communicated in his terse answers some of his desperation and sense of futility.
