She was not even as conscious as she should have been of the display on her screen, though this was not of very great importance. In principle, students were supposed to be observing while on watch; in practice, even the stuffiest of the Faculty would not expect much useful material to be picked up before the traveling classroom got a lot closer to Enigma. If anyone had known that Molly had already formed a working hypothesis and used it to plan her operations for the next few weeks, there would have been criticism; most of the red-sun races, if the individuals she had met so far were typical, were conservative in their ideas of where reasonable organization ended and wild speculation began. Even these, however, might have made allowance for her youth.

If asked, she could have claimed she was searching for Enigma at the moment. Presumably the body would be emitting the long waves characteristic of planetary temperatures, combined with reflected light from Arc; she had set her equipment to respond to such a combination and to center her screen on the source and shift to maximum resolution if it were found. Her mind, however, was elsewhere—though her eyes, like Joe’s side and rear ones, would put in a call for attention if their input pattern changed significantly. She was taking for granted, from the barely detectable sensation that had bothered her little Nethneen friend so greatly, that they were back on the real side of interface, but that left a couple of her days of ordinary flight before the laboratory site could be examined in any detail. Arc and its almost equally huge companion formed too massive a system to permit interface transfer at planetary distances; real space-time was too badly warped in their vicinity.

Enigma. Did the Faculty member of centuries past who had named the little planet have a sense of humor? Most intelligent beings did, of course. Actually, it was Enigma 88 in decimal notation—which, she reminded herself, was not used at the School. One of the things that had made her feel more at home, during her first weeks at Eta Carinae, had been the story of a major administrative upheaval, during the establishment of the place, over the question of octal or duodecimal time units.
