Few were attracted by its rugged growth, save in very warm weather, when hardy souls ventured within its borders to relax in artificial breezes created by silent concealed fans. In its center stood a small stone building that housed the maintenance machinery. It was deserted, except for once each year when the city engineering crews came to check the machines and to make minor repairs. There the Libero-Freedom Movement held its meetings, in the shadow of the whirring wheels. Sorgel came out of the shadows as Dirrul pushed through the thicket of brush that surrounded the stone building. In a hushed whisper he asked, "That you, Eddie?" "Yes--where are they?" "Inside. I gave them a hypo--they're both under now. It makes it easier." "How did it happen, Paul?" "I was to meet Glenna and Hurd at her apartment, to talk over the details of the Plan. The police were there ahead of me but I broke up the party before they could finish the job. Since they've got to do this sort of thing unofficially, to be able to deny it later if any questions are asked, I scared them off easily enough. I brought Glenna and Hurd here in my Unicyl but I'll need your help to get them out." "This is the second time it's happened, Paul!" said Eddie. "And the Plan--we'll have to organize all over again. As soon as our people hear about this most of them will run like scared rabbits." "Not if they don't know, Eddie. That's where you come in. We've got to get Glenna and Hurd away from Agron. If there's no evidence of a crime there's no reason for an investigation." "But what can I do?" "Borrow one of the Air-command's surface jets for a while." Paul Sorgel's plan was simple and efficient. The Air-Command field was fenced with electronic paralysis barriers and the entrance was heavily guarded. But no watch was kept inside the encampment except for a daily inspection of the machines when the guard was changed at dawn. Since Dirrul was a Captain of the Space-maintenance Division, 73rd Air-Command Wing, he was able to enter the area at any time without question. Among the scheduled night training flights for new cadets, the departure of one more surface jet would pass unobserved. "Come back here for Glenna and Hurd," Sorgel said, "and take them out to the South Desert. If there's no hitch you should be back before dawn, with time to spare. If not...." Sorgel shrugged. "Eddie, we can't build a better universe without taking occasional risks." Slowly Dirrul's body tensed with fear. In a cold dead voice he asked, "Am I to leave them there, without help or medicine, to die of thirst and hunger?" "Many sacrifices are necessary for the good of the Movement." "But Glenna and Hurd are our leaders!"
