 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. 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. "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.
