There was no need. No single individual could activate that access element; doing so required the combined and nearly simultaneous consent of three different human beings and two robot backups, each of whom received a different coded order from a different source. Any attempt to use it without the actions of all the others would result not only in a dead computer and blank terminal but also in a warning flashed to security.

The little man sat down in the chair, adjusted it for proper operating position, then leaned over and casually opened his briefcase. Removing a small crystalline device, he idly flicked it on with a thumb motion and then it set against the activation plate of the terminal.

The screen flickered, came to life. Printed on it were all the access codes as if it had received them and the question of whether the user preferred voice or CRT communication. There was no question of a print-out. Not with this computer.

“CRT only, please,” the little man idly said, in a thin, dry, nasal voice that bore no trace of accent. The machine waited. “Defensive files C-476-2377AX and J-392-7533DC, please, at speed.”

The computer seemed to blink at that last; at speed would be at roughly four hundred tines a second, the limit of the CRT to form the images in the first place. Nonetheless, the computer went to work. Both plans were delivered up and snapped past the little man in less than a second.

He was pleased. So much so that he decided then and there to press his luck a little and ask for more. “Run the master defense emergency plans, please, at speed, in order,” he told the machine casually.

The machine obeyed. Because of the volume of material it took almost four minutes.

The little man glanced at his watch. It was so tempting to continue, but every second he was here increased his chances of somebody just looking in or some random check. That wouldn’t do, not at all.
