They reached the waterfront. And here in the darkest part of the night and with the moon near to setting, the waters of the Bay of Naples rolled in small, smooth-surfaced, tranquil waves. There was a Navy barge waiting. Those who had come by plane boarded it. It cast off and headed out into the middle of the huge harbor. In minutes there was a giant hull looming overhead. They stepped out onto a landing ladder and climbed interminably up the ship's metal side. Then there was an open door. "Now," said the American colonel triumphantly, "now everything's all right! Nothing can happen now, short of an atomic bomb!" The Greek general glanced at him out of the corner of his eyes. He said something in that heavy accent of his. He asked mildly if creatures--Invaders--who could travel between the stars were unlikely to be able to make atom bombs if they wanted to. There was no answer. But somebody led Coburn into an office where this carrier's skipper was at his desk. He looked at Coburn with a sardonic, unfriendly eye. "Mr. Coburn, I believe," he said remotely. "You've been very well staged-managed by your friends, Mr. Coburn. They've made it look as if they were trying hard to kill you, eh? But we know better, don't we? We know it's all a build-up for you to make a deal for them, eh? Well, Mr. Coburn, you'll find it's going to be a let-down instead! You're not officially under arrest, but I wouldn't advise you to try to start anything, Mr. Coburn! We're apt to be rather crude in dealing with emissaries of enemies of all the human race. And don't forget it!" And this was Coburn's first inkling that he was regarded as a traitor of his planet who had sold out to the Invaders. All the plans made from his information would be based on the supposition that he intended to betray mankind by misleading it. [Illustration] V It was not yet forty-eight hours since Coburn had been interrupted in the act of starting his car up in Ardea. Greek newspapers had splashed lurid headlines of a rumored invasion by Bulgarians, and their rumored defeat. The story was not widely copied. It sounded too unlikely. In a few hours it would be time for a new set of newspapers to begin to appear. Not one of them would print a single word about the most important disclosure in human history: that extra-terrestrial Invaders moved blandly about among human beings without being suspected.
