The square of sidewalk dropped. Grant walked between X-ray scanners and remembered to deposit his heat-gun. He was met by an Earthman who took him up a long escalator. They went into a well-lighted room hung with rich tapestries and golden drapes. The man escorted Grant to a pedestal in the center of the room. The lights went out and it was inky black. Then suddenly there sprang into sight on the pedestal a transparent dome the size of a small goldfish bowl. It was lighted by ultra-violet from the bottom. In the center of the dome a small golden ball hung by a platinum wire, and on the ball was a tiny butterfly--Netse the Jovian. Netse's wings moved slowly as he walked around the ball, and the violet light brought out the delicate green luminous tracery in his wings. Grant involuntarily stepped back. There were whistling words and Grant was aware that they came through a speaker and amplification system. He knew the dome that protected the Jovian was almost indestructible. "You wished to see me?" The wings moved slowly back and forth. Each one had a purple spot in the center like an eye. Grant gulped. "Yes. I--I have something to show you. I need your help." He wondered if the purple spots actually were eyes. "Most people do," said Netse dryly. Grant, inordinately ill at ease, fumbled in his watch-pocket. It was incredible that this tiny butterfly that would hardly outweigh a cigarette paper should have the brain to conduct a ramified business such as this one, and it was even more incredible that men and everything else--except perhaps Relegar--would yield to its will. Will, of course, was the key factor. Will was dominant and men obeyed. * * * * * Grant held out the echindul stone. "This is one of a pair," he said. "I found the other one too." "You have just come back from the Red Lava Range," said the whistling voice. "How many pairs did you find?" Grant stared at the butterfly. Some thought the Jovians could read minds. Grant wondered. Then he decided to be honest. "Sixteen." Netse's wings quit moving for a minute. "What do you want me to do?" "I want you to assure me safe passage to your office. I will give you three-fourths of them," Grant blurted. He had not meant to make an offer like that. He had intended to let Netse ask but the delicacy of his situation hit him abruptly and fully and he was weighed down with sudden desperation. "How can you find the others?" asked Netse. "I--" Grant got cautious. "I have provided for that." The butterfly fluttered to the top of the dome and hung upside down for a moment. Then the whistling came again. "I am sorry. I do not see where I can be of any assistance." Grant was stunned. He held out both hands. "But--" The lights went out. The Earthman was at his side, leading him out. He was given his heat-gun. "But what--why?--I don't understand," Grant said, bewildered.
