Soon they were at the landing field and Gorla had run out the very air-sled that had brought Telis to the Temple City. Telis stepped into the forward cockpit and tested the jet. It came readily to life under his practised hands, and he motioned Gorla and the girl in beside him. "Fly low," the girl said almost pleadingly. He laid the stun-gun within easy reach and turned to Gorla. "Not that I don't trust you, my old friend," he said with a thin smile, "but I will feel much more comfortable if you are well-behaved while I am flying." Gorla made no reply. He merely shrugged and wrapped himself in his cassock as best he could. Telis glanced around at the sleeping field. Far across the landing area lights were flashing on. The sound of the air-sled's jet had awakened the attendants, and soon they would be giving the alarm. But there was no chance for anyone to stop them now. Almost disdainfully, Telis shoved the throttle forward on the quadrant and the jet roared. With a hissing of runners, the sled moved swiftly across the red sand and into the air. Zooming low over the buildings at the far end of the field, the sled drove out into the blackness. Then with breathtaking suddenness, it slashed through the light shield and the lights of Dorliss vanished while the heavens came alive with the early morning stars. Telis pointed the sled's blunt nose at the hatefully beautiful morning star that was Terra riding low on the eastern horizon. Presently, he levelled the craft and reduced his speed to maximum cruising power. Just skimming the reddish dunes, they sped eastward, into the sudden glory of the desert dawn.... IV At noon, Telis took time to search the sled's storage locker. Turning the controls over to the girl, he crawled across the bare deck into the rear cockpit. Most sleds that were used for over-desert flying carried emergency rations and weapons for the use of anyone unfortunate enough to need them. In the matter of weapons, he was doomed to disappointment, for this particular sled carried none. But there was a small packet of concentrates, and a flask of precious water. Telis gathered the packet in his arms and turned to start back toward the forward cockpit. He stopped short. From his vantage point behind her, Telis could see that the girl had taken a small cube from her pouch and was holding it to her ear. For several seconds she sat quite still, as though listening, then she turned the cube, held it to her lips for a moment, and returned it to the pouch at her belt. He scrambled back to his place beside her, demanding, "That cube. What was it?" "Cube?" "In there." Telis touched the pouch that hung at her side. "You must have been mistaken. There is no cube," she said, "Perhaps you saw me checking my compass...." She reached into the pouch and drew out a small magnetic compass in a square metal case. "You see?"
