"What is it?" she cried. "Come and look," he told her gravely, and made room for her. * * * * * At first she saw only the unwinking stars of space. Then her eyes shifted forward. Jupiter lay ahead, a vast cloud-girt disk. It was ominously near. Somehow it gave the effect of rushing straight at her. Right along the equator floated, or seemed to float, a huge red oval--the Great Red Spot of Jupiter. She had heard of it before. But what caught her immediate attention was a tiny flare of intense illumination, right in the very heart of the Spot. Bright orange it was, tinged with yellow, dazzling even at this distance. She watched it eagerly. Then she gave a sudden start. "You've seen it." Grant's voice sounded quietly in her helmet. "Yes. Why, it--it pulsates!" "Exactly. Now look along the hull of the ship." She did so, and gasped again. The steel-shod sides were bathed in an unearthly orange glow. "Why, that must be the light from the orange spot down there." Grant nodded. "Yes, and more than that. They are power waves of a nature that we've known nothing of before. We are being pulled down along that beam straight for Jupiter, straight for the source of that light!" "But that means there are intelligent beings on Jupiter." "No doubt." "But--but everyone know that there's no life on Jupiter. It's a frozen waste swathed in impenetrable whirlwind clouds." "How does everyone know?" Grant retorted. "Has anyone ever penetrated through those clouds?" "No," she admitted; "though there have been plenty of expeditions that tried, and never came back." "That of course doesn't prove anything. Mind you," he added. "I didn't say there was native life existing on Jupiter. I merely said there were intelligent beings operating that illumination." "Who could it be then?" "We'll find out when we get down there." * * * * * The very calmness of his matter-of-fact statement brought her back abruptly to their precarious situation. "But, great heavens, we'll smash and be killed. Can't we do something?" "We'll not smash." Grant said positively. "Though very likely we shall be killed. As for doing something, we can only wait and take our chances, if the gentry who are hauling us in will only give us an opportunity. You know," he added with a fine inconsecutiveness, "I don't even know your name." She bubbled with sudden laughter. "Nona--Nona Gail. I was on my way to Callisto, to meet my father," she explained. "He's an engineer, doing some construction work for Interspace Products. But now that I've told you all, what and who may you be?" He was frank. There was now no need for concealment. "Grant Pemberton, an unimportant unit of the Interplanetary Secret Service." "Then you knew that the trip would be dangerous," she challenged. "Yes." "Why did you come?" "It is part of my duties."
