Of course the man was fearful. He probably was reviewing his recent mistakes, wondering which one he might be called upon to explain. Too bad his mind wasn't clear enough to read. But what could you expect? Possibly, he could drive Research into improving the device later. "Anyway," he told himself, "everyone has something they're afraid of. It's natural. And everyone has their pet hates, too." For an instant, he thought of Harwood. He focused his mind on a single thought. "_Get me the quarters file for Sector Nine._" There was a definite effect this time. There was a sharp radiation of pained surprise. Then, there was acquiescence. The clerk started to say something, then backed toward the door. The impression of fear intensified. Morely smiled sardonically. The thing was an amusing toy, at that. He might find uses for it. He sat back, thinking. He could use it as a detector. Coupled with shrewd reasoning, well-directed questions, and his own accurate knowledge of human failings, it could tell him a great deal about his people and their activities. For instance, a question about some suspicious circumstance would cause a twinge of fear from the erring person. And that could be detected and localized. Further questions would produce alternate feelings of relief and intensified fear. He nodded complacently. Very little had ever gotten by him, he thought. But from now on, no error would remain undiscovered or unpunished. The clerk returned to place the file drawers convenient to his superior's desk. He hesitated a moment, his eyes on the headband, then picked up the completed papers from the desk and went out. Morely riffled through the cards, idly checked a few against his notes, and leaned back again. The file section seemed to be operating smoothly. He looked at his desk. Everything that had to be done immediately was done. And the morning was hardly more than half over. He rose to his feet. Surely, somewhere in the headquarters, there must be some sort of trouble spot. Somewhere, someone was not producing to the fullest possible. There must be some loose end. And he'd find it. He went out, jerking a thumb back at his office as he passed his clerk's desk. "You can pick up those files again, Roberts. And see to it that my office gets cleaned up a little. I won't be back for a while." He went out, to walk down the corridor to the snack bar. * * * * * There were a few girls there. He walked by their table, glancing at their badges. Communications people. He nodded to himself, ordered coffee, and chose a table.
