It was so near that they could not overtake her. It was so easy! Or it would have been but for the banths! The banths at night and the workers in the fields by day. Confined to the tower and without proper exercise or food, the girl failed to show the improvement that her captors desired. Ghek questioned her in an effort to learn why it was that she did not grow round and plump; that she did not even look as well as when they had captured her. His concern was prompted by repeated inquiries on the part of Luud and finally resulted in suggesting to Tara of Helium a plan whereby she might find a new opportunity of escape. "I am accustomed to walking in the fresh air and the sunlight," she told Ghek. "I cannot become as I was before if I am to be always shut away in this one chamber, breathing poor air and getting no proper exercise. Permit me to go out in the fields every day and walk about while the sun is shining. Then, I am sure, I shall become nice and fat." "You would run away," he said. "But how could I if you were always with me?" she asked. "And even if I wished to run away where could I go? I do not know even the direction of Helium. It must be very far. The very first night the banths would get me, would they not?" "They would," said Ghek. "I will ask Luud about it." The following day he told her that Luud had said that she was to be taken into the fields. He would try that for a time and see if she improved. "If you do not grow fatter he will send for you anyway," said Ghek; "but he will not use you for food." Tara of Helium shuddered. That day and for many days thereafter she was taken from the tower, through the enclosure and out into the fields. Always was she alert for an opportunity to escape; but Ghek was always close by her side. It was not so much his presence that deterred her from making the attempt as the number of workers that were always between her and the hills where the flier lay. She could easily have eluded Ghek, but there were too many of the others. And then, one day, Ghek told her as he accompanied her into the open that this would be the last time. "Tonight you go to Luud," he said. "I am sorry as I shall not hear you sing again." "Tonight!" She scarce breathed the word, yet it was vibrant with horror. She glanced quickly toward the hills. They were so close! Yet between were the inevitable workers--perhaps a score of them. "Let us walk over there?" she said, indicating them. "I should like to see what they are doing." "It is too far," said Ghek. "I hate the sun. It is much pleasanter here where I can stand beneath the shade of this tree." "All right," she agreed; "then you stay here and I will walk over. It will take me but a minute." "No," he answered. "I will go with you. You want to escape; but you are not going to." "I cannot escape," she said.
