Beardsley gulped again, stood frozen for half a minute. None of the techs seemed to notice; they had often chided him about it, but he was used to that now. At last he broke the spell and made his legs move, feeling cold sweat as he hurried along the length of ECAIAC toward Arnold's office. There ... just about there ... by the rheostats, where the four red lights and the two green made a baleful pattern against the black metal skin. He felt it stronger than ever this time, something reaching and sinister aimed solely at him. He skirted the place with a quick goosey hop, stumbled a little and felt panic, but made it all right to the office. Beardsley hated these moments. He was still trembling as he made a hurried entrance. Sure enough, as if on cue Jeff Arnold glanced up from his charts and grinned. "Ah, good morning, Beardsley! Now don't tell me our pet goo--uh--snapped at you again?" It was the routine remark, but today Arnold was immediately contrite for a change. "Sorry," he said, and a certain weariness replaced the grin. He gestured to the alco-mech. "Can I dial you a drink? Feel in need of one myself!" "Eleven-C," said Beardsley, and slumped into the pneumo-chair. Arnold rose and dialled 11-C, handed him the drink and dialled 9-R for himself. Sipping it, he moved around the desk. There was something very strange and preoccupied in his movements, Beardsley thought, more than a mere tiredness. He had never seen Arnold this way. "Yes sir, this is the day!" A muscle twitched in his corded neck; Arnold eased his long frame into a chair, rubbed thumb and forefinger at his eyes. "Been up half the night running off clearance tests. Can't afford to foul up on this one!" Beardsley tossed off his drink and blinked at the fiery strength of it. Now why should Arnold say that? When had ECAIAC ever fouled up? He watched the man across the desk. Jeff Arnold was a vigorous, striking specimen, handsome in an athletic way, with long stubborn jaw and unhappy gray eyes beneath his unruly hair; the sort of face that intrigues women, Beardsley catalogued from past experience. And, he added, altogether too young a man to be operating a monster like ECAIAC. * * * * * Arnold indicated the empty glass. "Another?" "No, I think not," Beardsley replied carefully. Arnold hesitated, eyeing the briefcase in Beardsley's clutch. "It's been rough on you, too, I imagine. Hope there aren't more than thirty variants! We're set up for more, of course, but it'll necessitate--" "Twenty-two," Beardsley assured him. Carefully, he spread the coded and sealed _persona-tapes_ across the desk. "Fresh from Citizen-File Augment, everything annotated and cross-checked. Blood-count, emotional stasis, plethora, psycho-geneological index, neuro-thalamic imbalance--every type factor is here. We really went to the Files on this case." "Looks as if you did! How does it narrow down?"
