The Interlevel Limited left the lower warmth and streaked up the great winding tunnel through the neat residential suburbs, through the squalid upper levels, through the ice-locked roots of ancient Manhattan. But Steel barely noticed when the windows in his compartment frosted over. He was studying his glacier maps. The comet crater was located near the frozen ruins of what was once a surface city named Jersey. He'd been on a snow-deer hunt up there once; an old guide had told him about the ice-bear cubs. Steel plotted his course from the Surface Terminal to the Ruins, then checked his equipment list--electrosuit, oxygen helmet, volt rifle, rations. He'd charter a little ski plane at the Terminal. When he finished, he leaned back in his seat and glanced at his watch. Almost there. Had he forgotten anything? Fitted into the oxygen helmet was a little radio unit so he could keep in touch with Stahl. He'd set up a receiver in a vacant room in the Vita-Heat Building and arranged for one of Stahl's guards to be there at all times. He'd also arranged for Stahl to send a copy of their contract--reward or insurance--to Commissioner Brandt. Not that he didn't trust Stahl.... Well, it looked as if he was all set. He'd buy a hunting license to put on the ski plane--for all anybody'd know he was out for snow-deer. He'd spend the night at the Terminal Hotel, leave first thing in the morning.... When the Limited's whirring ceased, he put away the maps and picked up his bag. As the outer door slid open, he stepped out into the vast Terminal and headed for the viewway that would take him to the hotel. The Terminal was a heavily insulated cavern in the ice crust. The landing and departure stalls encircled the huge room where the motley thousands of hurrying travelers bought tickets, waved goodbyes or greetings, or waited sleepily around Dr. Albert Harmon's chrome statue. As Steel passed the statue of the shaggy-haired bespectacled old man, he eyed it thoughtfully. Dr. Harmon's experiments with household and jet propulsion heat had done a lot of good but it looked as if his green-eyed daughter wasn't good for anything but a cocktail party.... Then he was on the viewway. His spine tingled at the sight outside.
