An instant later, he was back beside the posters where he had hidden a transceiver earlier. Two men were walking in the same direction he had gone. Dan followed them till they vanished, walking very rapidly now, around another corner. He picked up the mataform transceiver and looked around for the blocky structure with the big number "10" over it. He saw it, after a moment, near the wall with the lights and moving letters on it. "Kielgaard," he thought, "what do you suppose that wall is?" "We think it's a sort of abbreviated classified ad arrangement." "Sounds reasonable," Dan thought. Dan was by now near the blocky structure with the big numeral "10" above it. Each of the four faces of the structure had four large doors outlined on it--one door for each of the sixteen sections of the level. Dan stepped up to the door marked "4" and it was immediately outlined in red. A voice said, "Travelers are reminded of the special restrictions now enforced at the governmental sections. To enter, you must present valid authorization papers, or state an acceptable reason for entering." Dan stood perfectly still. He was fairly sure now that he must get into this section. But how? At that moment, the lights of the huge wall of moving letters caught his attention, and Kielgaard's voice said, "Dan, look to the left, about halfway up." Dan looked and saw moving letters spell out: S WANTED ON LEVEL 10 ALL CREDITS PAID SHORT TERM EMPLOYMENT *MEN WITH FAST REFLEXES WANTED ON LEVEL 10 * * * * * Dan realized he had seen parts of this ad spelled out twice at the terminal entrance. He didn't know if it was a trap or something he could use. He said, "I'm interested in a job on Level 10." "You have examined the record?" Dan had no idea what this meant. He said, "I understand men with fast reflexes are wanted on Level 10." "One moment." There was a short pause, then a new voice. "What we offer you is a special credit allotment sufficient for all normal mating and purchase needs. On account of these latest restrictions, I can't tell you exactly what the job is, but I can say this: The rewards are great. But you also might end up getting sprinkled over the forest. We've got a situation down here that has to be cleaned up fast. With the special referendum tomorrow, it might boil over and make an interstellar mess. We want you for a night's work. At the end you're either rich or dead. How about it?" Dan thought of the two words "interstellar mess," used in connection with a "special referendum." He had the sensation that he was getting close. "All right," he said. * * * * * There was a blur as mataform stations shuttled him from one place to the next. Then he was walking into a large room holding about thirty men, all of whom had something of the look of big cats alert for prey.
