For there was something about Raoul Beardsley that eternally evoked amusement--an air of vacuous innocence and a remote forlornness. He gave the appearance of a person who sold shoes during the day, washed his wife's dishes at night and then solved two or three galacti-gram puzzles before turning off the light precisely at ten. Few, if any, remembered that this nervous little man had once been top Inspector of New York City's Homicide Bureau ... but that was a dozen long years ago. Since then he had seen the antiquated detective methods of 1960 disappear, and he had died a little, too, seeing his Homicide Bureau relegated to a mere subsidiary with the growth of the Coördinate and Mechanical Divisions. His appointment to Chief of Co-ördinants, Federal, was automatic and unquestioned; and Beardsley would have been the last to know, or to care, that he had correlated some eight million miles of serological data for the entrains of ECAIAC, a perfect record of not a single unsolved case. And the penalty was in his eyes, if one cared to look beyond the thick-lensed glasses. No one ever did. They were remote eyes, a little bewildered, a little hurt ... a mirror gone dull from times remembered but irretrievably lost. * * * * * Beardsley stepped onto the corridor slidewalk, coasted to the escalator and rode it down. Still immersed in his thoughts, he pushed into ECAIAC's room ... _and again it happened_. So shockingly sudden, there was not even time for remonstrance at himself. The feeling hit him as always before, straight and unerring, a surging impact that smashed forward and stopped him in his tracks, literally paralyzed. He caught his breath convulsively. How often had he come here? And how often had this happened, even when he'd sworn he wouldn't let it? There was something about the sight and sound and feel of ECAIAC that got to him, that seeped beneath flesh and bone and into his brain and sent his senses singing. Beardsley managed to gulp, as he observed the shiny black colossus that filled the entire length of the ninety-foot room; a dozen techs scurried around it, taking notes, attentive to the flashing lights in red-and-green and the faint clicking of thousands of relays that rose in susurration. But more than that arose. It was something that pervaded the room, not a pulsing but a _presence_, a sort of snapping intangible intelligence that reached beyond the audible and sheared at Beardsley's nerve-ends. And it hadn't been there a moment before. That was the shocking thing. Beardsley knew that it _knew_! It was sentient, it was alive and aware and waiting, and it was listening. As always, it knew that _he_ had entered.
