"But that makes it solid, Sis!" Kit exclaimed.

"That's what I thought, for a minute—that we had Boskone at last. However, when Tregonsee and I first felt 'X,' long before you met yours, Kat, his classification was TUUV. That would fit in well enough as a spring form, with Kat's as the summer form. What ruins it, though, is that when he killed himself, just a little while ago and long after a summer form could possibly exist—to say nothing of a spring form—his classification was still TUUV. To ten places it was TUUVWYXXWT."

"Well, go on," Kinnison suggested. "What do you make of it?"

"The obvious explanation is that one or all of those entities were planted or primed—not specifically for us, probably, since we are relatively unknown, but for any competent observer. If so, they don't mean a thing." Camilla was not now overestimating her own powers or underestimating those of Boskonia. "There are several others, less obvious, leading to the same conclusion. Tregonsee is not ready to believe any of them, however, and neither am I. Assuming that our data was not biased, we must also account for the fact that the locations in space were—"

"Just a minute, Cam, before you leave the classifications," Constance interrupted. "I'm guarded—what was my friend's, to ten places?"

"VWZYTXSYZY," Camilla replied, unhesitatingly.

"Right; and I don't believe that it was planted, either, so there—"

"Let me in a second!" Kit demanded. "I didn't know that you were on that band at all. I got that RTSL thing even before I graduated—"

"Huh? What RTSL?" Cam broke in, sharply.

"My fault," Kinnison put in then. "Skipped my mind entirely, when she asked me for the dope. None of us thought any of this stuff important until just now, you know. Tell her, Kit."
