That was one part of it. The other was that numerous contentious factions in the space cities and on the so-called open worlds wanted to spill over on the Freeholder planets. Again the Overgovernment refused, and again it made sense to Dowland. But the Freeholders feared--perhaps with justification, so far as Dowland could tell--that political pressures would mount with each increase in excess population and eventually lead to such measures. Many of them, probably the majority, led by Anthony Brand Carter--Firebrand Carter, head of the largest and wealthiest of the Families--believed that the only safe solution was to arm the planet. They wanted heavy weapons, and enough of them: the right to build them, to man them and, if necessary, to use them to beat off encroaching groups. The Overgovernment pointed out that the possession and use of major implements of war was by law its own exclusive privilege. Litigation on the matter had gone on for decades, was periodically renewed by Carter and his associates. Meanwhile, many of Terra's sportsmen became members of an extremely able-bodied group called Carter's Troopers, and assiduously practiced the skills of battle with the means allowed them. Dowland and the Solar Police Authority knew the Troopers were crack shots, excellent fliers and horsemen, but the Overgovernment was not worrying about it at present. Mr. Paul Trelawney, the younger of the brothers, had been a Trooper for two years while in his twenties, then had quarreled violently with Firebrand Carter, had left Terra to major in physics at the Overgovernment's universities, and presently received his degree. What he had done after that wasn't known. He appeared occasionally on Terra, might be here at present. Miguel, Paul's senior by almost twenty years, now in his early fifties, had also taken an interest in physics, attending an Overgovernment university a quarter of a century earlier. Miguel's studies terminated before he obtained a degree, as a result of a difference of opinion with the president of the university, whom he challenged to a duel. The records of both brothers indicated, in Dowland's opinion, more than a trace of the megalomania not too uncommon among men with excessive wealth and no real claim to distinction. But, in spite of their choice of studies, there was nothing to link either Trelawney to the missing YM. Mental brilliance might have made them suspect; but their I.Q. readings, while definitely better than average--a number of notches above Dowland's own, for that matter--were not outstanding. Their scholastic performance had been of comparative quality. Miguel, on his return to Terra, had dropped physics in favor of experimental biology. The ranch on Lion Mesa was adapted to his hobby, which at the moment was directed to the production of a strain of gigantic wild hogs for hunting purposes. Presumably the breeding of bad-tempered tons of bacon on the hoof
