Karson stared at the thick-featured face framed by the visiscreen. "You've won again," he said after a pause. "We can't fight you, Lugert. How much time do we have to evacuate the Government Building?" "How much do you need?" Karson thought for a moment. "A week, at least. Is that all right?" "One week, no more," Lugert agreed. "My men and I will come up to take over things at noon on 7 September." He chuckled. "7 September, 2531. A day to go down in history, eh, Karson?" He broke the contact. * * * * * Karson turned from the dead screen and looked at Speaker Darell. "Well, there's our ultimatum," he said. "One week to get out and then Lugert takes over." "That means we'll have to move fast," said Darell. "You'd better call Dr. Lorence. Only a week...." Karson was already busy punching out Lorence's code number on the visiphone. When the scientist appeared Karson quickly sketched out the situation as it stood. Lorence's eyes widened when Karson told of Lugert's threat. Then the Speaker went on to outline the part Lorence and his time-net would play in the attempt to defeat Lugert. "I'll see what I can do," Lorence promised. "I'll try to find the man you're looking for." "Can you do it in two days or less?" "I hope so," Lorence said. It took two days. Then Lorence rang the Office of the Council and told Karson, "It's worked!" "The time-net? You've got the man?" "I have. I'll bring him right over." Lorence entered the council room a while later, followed by a tall, thin, lean-faced man dressed in archaic clothing. Karson's heart thumped excitedly; here was the man, he thought! Here was the hero from yesteryear who would put an end to the threat Lugert represented. "This is Speaker Karson and Speaker Darell of our governing Council," Lorence said. The man from the past nodded curtly. "You can call me Jack." His voice was cold, flat, with a curious twang of regional accent in it; the vowel-pronunciation was odd, as was to be expected. Karson eyed the hard-faced stranger. He didn't seem to have an ounce of fat on him; he looked tough, uncompromising. "I think you'll do," he said after a moment's study. "You've got the stuff." "Thanks," Jack said in a wry voice. "Suppose you line the program out for me now. Give me the picture; tell me what I'm here for." Karson frowned. "You're here to help us, because we're helpless ourselves. Did Dr. Lorence tell you what the characteristics of this world are?" "He said a few things. You fill me in." "It's 300 years since we last had a war of any sort. Crime had been extinct 150 years--until Lugert. "Lugert. I heard of him. Who is he?" "He's the man you're going to kill for us," Karson said bluntly. The man named Jack grinned. "Oh? A rub-out job?"
