In spite of the treaties and acceptance of peaceful measures made on the part of the Martians, there was always the chance that some underhanded move might be made. There was that edge to life; that fine, razor-sharp edge of excitement and danger. Mars might make untoward moves, but it was not all Mars' party. Terra made her own espionage and operations tended to display her might to the Red Planet. Brushes that never reached notice were always going on. He permitted himself to wax enthusiastic over his being home again. They never knew that it was not merely the release from space loneliness but a return from a too long, too uneventful vacation. He considered himself objectively one day after he found himself looking forward to the return to Terra. The investigation did not bother him; it was the question of whether his year of absence from the service would cause him a year's loss in advancement. If it caused him no loss, he would become a Senior Executive within a month or so after his return. That would give him the right to captain a destroyer like this one. His interest and anxiousness to return to Terra had become honest. On Ertene he had argued against it. Now he knew his mind and also knew that Charalas had done the proper thing. He would not have remained on Ertene. Some day the everlasting peace and quiet would get him, and then there would have been trouble. He owed them his life, and if some of the things in his log worked to his own satisfaction, he owed them more than that. He'd keep their secret; denying Terra the right to exploit Ertene was hard, but better deny them that than to deny them the knowledge he had gained. Terra would hold dominance over the Solar System without Ertene's presence; though it was not without Ertene's help. Poor Ertene. A sterile, placid life that was beginning to look pale and uninteresting against the rugged, boisterous existence of men who roamed the Solar System. Let them have their stability. What was their history? A few thousand years since the dawn of their written lore? Far greater than Sol's though he had been loath to tell them that. At that time such an admission was like admitting that one was but an adolescent. But it was true. But in those thousands of years, had their science come a comparable distance with Terra's? And Guy knew why. With nothing to strive against, progress ceases. He wondered whether the investigating committee would make an issue of the fact that a junior executive had been so oblivious to his duty as to permit capture by Martians. That was the only fly in his ointment, the only point over which he worried. He felt that his capture could have happened to anyone, and secretly he admired the bold stroke in the light of how daring it had been for Mars to storm the very ramparts of Sahara Base. But investigating committees are strange things and their decisions are often based on theory instead of action with no regard to circumstances.
