Jason spent one depressed day lying on his bunk counting rivets, forcing himself to accept defeat. Kerk's order that he was not to leave the sealed building tied his hands completely. He felt himself close to the answer--but he was never going to get it. One day of defeat was all he could take. Kerk's attitude was completely emotional, untempered by the slightest touch of logic. This fact kept driving home until Jason could no longer ignore it. Emotional reasoning was something he had learned to mistrust early in life. He couldn't agree with Kerk in the slightest--which meant he had to utilize the ten remaining days to solve the problem. If it meant disobeying Kerk, it would still have to be done. He grabbed up his noteplate with a new enthusiasm. His first sources of information had been used up, but there must be others. Chewing the scriber and needling his brain, he slowly built up a list of other possibilities. Any idea, no matter how wild, was put down. When the plate was filled he wiped the long shots and impossibles--such as consulting off-world historical records. This was a Pyrran problem, and had to be settled on this planet or not at all. The list worked down to two probables. Either old records, notebooks or diaries that individual Pyrrans might have in their possession, or verbal histories that had been passed down the generations by word of mouth. The first choice seemed to be the most probable and he acted on it at once. After a careful check of his medikit and gun he went to see Brucco. "What's new and deadly in the world since I left?" he asked. Brucco glared at him. "You can't go out, Kerk has forbidden it." "Did he put you in charge of guarding me to see if I obeyed?" Jason's voice was quiet and cold. Brucco rubbed his jaw and frowned in thought. Finally he just shrugged. "No, I'm not guarding you--nor do I want the job. As far as I know this is between you and Kerk and it can stay that way. Leave whenever you want. And get yourself killed quietly some place so there will be an end to the trouble you cause once and for all." "I love you, too," Jason said. "Now brief me on the wildlife." The only new mutation that routine precautions wouldn't take care of was a slate-colored lizard that spit a fast nerve poison with deadly accuracy. Death took place in seconds if the saliva touched any bare skin. The lizards had to be looked out for, and shot before they came within range. An hour of lizard-blasting in a training chamber made him proficient in the exact procedure. * * * * * Jason left the sealed buildings quietly and no one saw him go. He followed the map to the nearest barracks, shuffling tiredly through the dusty streets. It was a hot, quiet afternoon, broken only by rumblings from the distance, and the occasional crack of his gun. It was cool inside the thick-walled barracks buildings, and he collapsed onto a bench until the sweat dried and his heart stopped pounding. Then he went to the nearest recreation room to start his search. Before it began it was finished. None of the Pyrrans kept old artifacts of any kind and thought the whole idea was very funny. After the twentieth negative answer Jason was ready to admit defeat in this line of investigation. There was as much chance of meeting a Pyrran with old documents as finding a bundle of grandfather's letters in a soldier's kit bag. This left a single possibility--verbal histories. Again Jason questioned with the same lack of results. The fun had worn off the game for the Pyrrans and they were beginning to growl. Jason stopped while he was still in one piece. The commissary served him a meal that tasted like plastic paste and wood pulp. He ate it quickly, then sat brooding over the empty tray, hating to admit to another dead end. Who could supply him with answers? All the people he had talked to were so young. They had no interest or patience for story-telling. That was an old folks' hobby--and there were no oldsters on Pyrrus. With one exception that he knew of, the librarian, Poli. It was a possibility. A man who worked with records and books might have an interest in some of the older ones. He might even remember reading volumes now destroyed. A very slim lead indeed, but one that had to be pursued. Walking to the library almost killed Jason. The torrential rains made the footing bad, and in the dim light it was hard to see what was coming. A snapper came in close enough to take out a chunk of flesh before he could blast it. The antitoxin made him dizzy and he lost some blood before he could get the wound dressed. He reached the library, exhausted and angry. Poli was working on the guts of one of the catalogue machines. He didn't stop until Jason had tapped him on the shoulder. Switching on his hearing aid, the Pyrran stood quietly, crippled and bent, waiting for Jason to talk. "Have you any old papers or letters that you have kept for your personal use?" A shake of the head, no. "What about stories--you know, about great things that have happened in the past, that someone might have told you when you were young?" Negative. Results negative. Every question was answered by a shake of Poli's head, and very soon the old man grew irritated and pointed to the work he hadn't finished. "Yes, I know you have work to do," Jason said. "But this is important." Poli shook his head an angry no and reached to turn off his hearing aid. Jason groped for a question that might get a more positive answer. There was something tugging at his mind, a word he had heard and made a note of, to be investigated later. Something that Kerk had said ... "That's it!" It was right there--on the tip of his tongue. "Just a second, Poli, just one more question. What is a 'grubber'? Have you ever seen one or know what they do, or where they can be found--" The words were cut off as Poli whirled and lashed the back of his good arm into Jason's face. Though the man was aged and crippled, the blow almost fractured Jason's jaw, sending him sliding across the floor. Through a daze he saw Poli hobbling towards him, making thick bubbling noises in his ruined throat; what remained of his face twisted and working with anger. This was no time for diplomacy. Moving as fast as he could, with the high-G, foot-slapping shuffle, Jason headed for the sealed door. He was no match for any Pyrran in hand-to-hand combat, young and small or old and crippled. The door thunked open, as he went through, and barely closed in Poli's face. Outside the rain had turned to snow and Jason trudged wearily through the slush, rubbing his sore jaw and turning over the only fact he had. Grubber was a key--but to what? And who did he dare ask for more information? Kerk was the man he had talked to best, but not any more. That left only Meta as a possible source. He wanted to see her at once, but sudden exhaustion swept through him. It took all of his strength to stumble back to the school buildings. * * * * * In the morning he ate and left early. There was only a week left. It was impossible to hurry and he cursed as he dragged his double-weight body to the assignment center. Meta was on night perimeter duty and should be back to her quarters soon. He shuffled over there and was lying on her bunk when she came in.............
