 What is the significance of the title of the story?
A pair of guards, their purple hides smoothly polished and gleaming with oil, crossed their ceremonial pikes in front of him as he approached the entrance. "And just what business do you have here, stranger?" asked the senior of the guards, his speaking orifice framing with difficulty the sibilances of Universal Galactic. "Just tell him that a man has arrived from Earth to talk to him. An elegant courtier, with elaborately jeweled harness, bustled from inside the palace, obviously trying to present an air of strolling nonchalance. "But then I'm told you're an Earthling. "It was only decided yesterday, back on Earth, that I would be the one to make the trip here. What I meant was that I expected someone from Earth to break through our blockade and come here. "If you wanted someone from Earth to come here to see you, why did you put the cordon around Earth? And why did you drop a planet-buster in the Pacific Ocean, and tell us that it was triggered to go off if we tried to use the distorter drive? There are more inhabited planets in the Galaxy than there are people on your single world. There was even serious discussion of destroying Earth out of hand, while it is still possible. While these creatures could by no means be classed among the intelligent races, there was a general expectation, which we reported to the Sunda, that they would some day come to be numbered among the Servants of the Emperor. As an Earthling, you have heard of the details of the first expedition of your people into space, of course?" " Heard about it?" exclaimed Crownwall. He settled down comfortably on a couch, without requesting permission, and thought back to that first tremendous adventure; an adventure that had taken place little more than ten years before. The men of Earth had decided that it should work in theory. To do so, said their theory, would usually—seven point three four times out of 10—destroy the ship, and everything in space for thousands of miles around, in a ravening burst of raw energy. They had headed for that planet confidently and unsuspectingly, using the ion drive. Two weeks later, while they were still several planetary diameters from their destination, they had been shocked to find more than two score alien ships of space closing in on them—ships that were swifter and more maneuverable than their own. On the distorter drive, they had returned to Earth as swiftly as they had departed.
