 What likely happens to Crownwall after the story is over?
John Crownwall, florid, red-headed and bulky, considered himself to be a bold man. If they carried out the threats of their present attitude, Earth would have to send Marshall to replace him. Instantly, and unexpectedly to Crownwall, the threatening crowd dropped back fearfully, so that he walked the last fifty meters alone. 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. If you know what's good for you, you'll get out of here while you can still walk. Crownwall sat on the steps, puffed alight a cigarette, and blew expert smoke rings toward the guards. Crownwall stamped out his smoke and ambled after the hurrying courtier along tremendous corridors, through elaborate waiting rooms, under guarded doorways, until he was finally bowed through a small curtained arch. 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? There was even serious discussion of destroying Earth out of hand, while it is still possible. It had been manned by a dozen adventurous people, captained by Crownwall, and had headed out on its ion drive until it was safely clear of the warping influence of planetary masses. 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. Although far within the dangerous influence of a planetary mass, they had again activated the distorter drive, and they had beaten the odds. You knew that you could have destroyed not only yourself, but also all who live on that planet. You could also have wrecked the planet itself and the ships and those of my own race who manned them. With your total lack of information about us, what you did was more than the height of folly. "Could we have done anything else that would have kept you from landing on Earth and taking us over?" asked Crownwall. Even if you could get down to the bottom of the ocean and tamper with the bomb, you would only succeed in setting it off, and that's what the Sunda had been in favor of in the first place.
