He got off the moving strip as soon as the lights of the center of the city were clear below, and stepped into the self-operated lift that sped down to ground level. From the elevator, he moved on to one of the long, honeycombed concourses, filled with passing shoppers who stared at the colorful, enticing three-dimensional displays. At one of the intersections ahead, he spotted a visiphone station, and dropped onto the little seat before the screen. There had been a number, if only he could recall it. But as he started to dial, the silvery screen shattered into a thousand sparkling glass chips, showering the floor with crystal and sparks. Harry cursed, grabbed the hand instrument, and jangled frantically for the operator. Before she could answer, the instrument grew warm in his hand, then hot and soft, like wax. Slowly, it melted and ran down his arm. He bolted out into the stream of people, trying desperately to draw some comfort from the crowd around him. He felt utterly alone; he _had_ to contact the not-men who were in the city, warn them, before they spotted him, of the attack he carried with him. If he were leading his pursuer, he could expect no mercy from the ones whose help he sought. He knew the lengths to which they would go to remain undetected in the society around them. Yet he had to find them. In the distance, he saw a figure waiting, back against one of the show windows. Harry stopped short, ducked into a doorway, and peered out fearfully. Their eyes locked for an instant; then the figure moved on. Harry felt a jolt of horror surge through him. Dr. Webber hunting him in person! He ducked out of the doorway, turned and ran madly in the opposite direction, searching for an up escalator he could catch. Behind him he heard shots, heard the angry whine of bullets past his ear. He breathed in great, gasping sobs as he found an almost empty escalator, and bounded up it four steps at a time. Below, he could see Webber coming too, his broad shoulders forcing their way relentlessly through the mill of people. Panting, Harry reached the top, checked his location against a wall map, and started down the long ramp which led toward the building he had tried to call. Another shot broke out behind him. The wall alongside powdered away, leaving a gaping hole. On impulse, he leaped into the hole, running through to the rear of the building as the weakened wall swayed and crumbled into a heap of rubble just as Webber reached the place Harry had entered. Harry breathed a sigh of relief and raced up the stairs of the building to reach a ramp on another level. He turned his eyes toward the tall building at the end of the concourse. There he could hide and relax and try, somehow, to make a contact. Someone fell into step beside him and took his arm gently but firmly. Harry jerked away, turning terrified eyes to the one who had joined him.
