Winding their way easily upward, Dirk and Inga came finally to a secluded terrace which overlooked the Sound. Here they saw Stanton, who was unaware of their approach, looking skyward at the dim and sinister shape which was outlined against the sky. Stanton's brow was contracted and his expression was filled with apprehension. He started suddenly when he became conscious of the presence of Dirk and the lovely daughter of Fragoni. He rose to his feet, a short man in his forties, stocky in build and somewhat swarthy in complexion. He contrasted very unfavorably with Dirk, who was tall and well-built and who had abundant blond hair and steady steel-blue eyes. "What do you make of that thing, Vanderpool?" he asked, almost ignoring the presence of Inga. "I don't know enough about it yet to be able to express an opinion," Dirk replied. "We will find out about it soon enough," he added, "so why worry about it in the meantime?" "It is well enough to affect such an attitude," said Stanton, with a touch of sarcasm in his voice, "but let me tell you, Vanderpool, that there is good reason to worry about it." * * * * * Dirk frowned at the statement as he saw a shadow pass over the fair face of Inga. "That thing up there," continued Stanton, with conviction in his voice, "is not a natural phenomenon. I flew fairly close to it in my plane and I know what I am speaking about. That thing is some sort of a monster, Vanderpool, that is made of metal or of some composition that is an unearthly equivalent of metal. It is a diabolical creation of some sort that has come from out of the fathomless depths of the universe." He shuddered at the fantasy that his feverish imagination was creating. "It is metal, I tell you," he continued, "but it is metal that is endowed with some sort of intelligence. I was up there," he breathed swiftly, "and I saw it hanging there in the sky, quivering with heat and life." "You are nervous, Stanton," said Vanderpool coolly. "Get a grip on yourself, man, and look at the thing reasonably. If that thing has intelligence," he added, "we will find some way to slay it." "Slay it!" exclaimed Stanton. "How can you expect to slay a mad creation that can leap through space, from world to world, like a wasp goes darting from flower to flower? How can you kill a thing which not only defies absolute zero but also the immeasurable heat which its friction with the atmosphere generated when it plunged toward the earth? How can you kill a thing that seems to have brains and nerves and bones and flesh of some strange substance that is harder and tougher than any earthly compound we have discovered?" * * * * * He stopped speaking for a moment. They listened to the voice that was broadcasting from the Worldwide Tower.
