Dowland rubbed the side of his nose, scowling slightly. If the ranch really was deserted, it would be best to leave it alone for the time being and search elsewhere for Trelawney. To go down uninvited in the absence of the owner would be as much out of character for an experienced visitor on Terra as for a Freeholder. If observed at it--a remote possibility perhaps in this area, but the possibility was there--he could offer the excuse of a suspicion of engine trouble in the grid-car. The excuse would be good, once. He preferred to reserve it as a means of introducing himself to the Trelawneys when he caught up with them--either Miguel, the current head of the dwindled family, or Miguel's younger half-brother, Dr. Paul Trelawney. Neither rated as a serious suspect in the matter of the Overgovernment's missing Ym-400, but it had been a little difficult to find out what they had been doing with themselves during the past year and a half. Dowland's assignment was to find out, and to do it unobtrusively. Strictly routine. * * * * * Terra, in terms of the YM search, hadn't seemed like too bad a bet at first. The Freeholders entertained an open grudge against the Overgovernment, which had restricted their nominally unclouded title to the planet by somewhat underhanded legal means, when the principle of the Freehold Worlds was laid down. Essentially, the Families became the very highly paid caretakers of Terra. To Dowland, raised in the crowded tunnels of the system of artificial giant asteroids known as Solar City, the conservation of the natural resources of a living world looked like a good idea. The Terran Families were interested in conservation, but on their terms and under their control. The Overgovernment politely refused.
