Cameron whipped back through the pages of the histories, searching only for a single item, one clue to the swift evolution from barbarism to peaceful co-operation. After an hour he was in the middle of that critical period when the Council despaired of its inability to cope with the Markovian menace.

But the stories of commerce and invention and far-flung exchange with other peoples continued. Nowhere was there any reference to the violence of the period. They went back two hundred—five hundred years—beyond the time when Council members first made contact with the Nucleus.

There was nothing.

Cameron sat back in complete puzzlement as it became apparent that it was useless to go back further. "The normal thing would be for them to brag all over the place about their great conquests. Even races who become comparatively civilized citizens ordinarily let themselves go when it comes to history. If they've had a long record of conquest and bloodshed, they say so with plenty of chest pounding. Of course, it's padded out to reflect their righteous conquest over tyranny, but it's always there in some form.

"But nothing up to now has been normal about the development of the Markovian problem and this really tops it off—the complete omission of any reference to their armed conquests."

"Maybe this planet didn't participate very much. Perhaps only a small number of the Nucleus worlds were responsible for it," said Joyce.

Cameron shook his head. "No. The Council records show that the Nucleus as a unit was responsible, and that virtually all the worlds are specifically mentioned. And even if this one had been out of it completely you could still expect references to it because there was constant interchange with most of the other planets. We can try another one, though—"

They tried one more, then a half dozen in quick scanning. They swept through a summarization of the Nucleus as a whole during that critical period.

There was nothing to show that the Markovians had ever been anything but peace-loving citizens intent on pursuit of science, commerce, and the arts.

"This could have been rigged for our special benefit," said Joyce thoughtfully as they ended the day's futile search. "They didn't want to apply enough pressure to keep us from coming, but they did want to make sure we wouldn't find out anything about their past."
