Stephanie watched the intruder vanish with a sense of wonder which only grew as the creature disappeared. It was small, she thought, no more than sixty or seventy centimeters long, though its tail would probably double its body length. An arboreal, her mind went on, considering its tail and the well-developed hands and the claws she'd seen as it clung to the lip of the louver. And those hands, she thought slowly, might have had only three fingers each, but they'd also had fully opposable thumbs. She closed her eyes, picturing it once more, seeing the net on its back, and knew she was right.

The celery snatcher might look like a teeny-tiny hexapuma, but that net was incontrovertible evidence that the survey crews had missed the most important single facet of Sphinx. But that was all right. In fact, that was just fine. Their omission had abruptly transformed this world from a place of exile to the most marvelous, exciting place Stephanie Harrington could possibly have been, for she'd just done something which had happened only eleven other times in the fifteen centuries of mankind's diaspora to the stars.

She'd just made first contact with a tool-using, clearly sentient, alien race.

The only question now was what to do about it.

Climbs Quickly lay on his back outside his nest, belly fur turned to the sun, and did his best to convince the rest of his clan he was asleep. He knew he wasn't fooling anyone who cared to taste his mind glow, but good manners required them to pretend he was.

Which was just as well, for blissful as it was, the comfort of the drowsy sunlight was far too little to distract him from the monumental changes in his life. Facing his clan leaders and admitting that he'd let one of the two-legs actually see him — and even worse, see him in the very process of raiding their plant place — had been just as unpleasant as he'd feared.

People seldom physically attacked other People. Oh, there were squabbles enough, and occasional serious fights — usually, though not always, limited to younger scouts or hunters — and even rarer situations in which entire clans found themselves feuding with one another or fighting for control of their ranges. No one was particularly proud of such situations, but the ability to hear one another's thoughts and taste one another's emotions didn't necessarily make other People any easier to live with or fill a clan's range with prey when it was needed. But a clan's leaders normally intervened before anything serious could happen within a clan, and it was rare indeed for one member of a clan to deliberately attack another unless there was something fundamentally wrong with the attacker. Climbs Quickly himself could remember an occasion on which High Crag Clan had been forced to drive out one of its scouts, a rogue who had attacked other People. The exile had crossed into the Bright Water range, killing prey not just to live but for the sheer joy of killing, and raided Bright Water's storage places. He'd even attacked and seriously injured a Bright Water scout while attempting to steal a mother's kittens… for purposes Climbs Quickly preferred not to consider too deeply. In the end, the clan's scouts and hunters had been forced to hunt him down and kill him, a grim necessity none had welcomed.

So Climbs Quickly hadn't expected any of the Bright Water leaders to assault him, and they hadn't. But they had left him feeling as if they'd skinned him and hung his hide up to dry. It wasn't even the things they'd said so much as the way they'd said them.

Climbs Quickly's ears flicked, and he squirmed, turning to catch the sun more fully, as he recalled his time before Bright Water's leaders. Sings Truly had been present as the clan's second singer and the obvious heir to the first singer's position when Song Spinner died or surrendered her authority, but even Sings Truly had been shocked by his clumsiness. She hadn't scolded him the way Short Tail or Broken Tooth had, yet tasting his sister's wordless reproach had been harder for Climbs Quickly to bear than all of Broken Tooth's cutting irony.

He'd tried to explain, as clearly and undefensively as possible, that he'd never meant to let the two-leg see him, and he'd suggested the possibility that somehow the two-leg had known he was in the plant place even before seeing him. Unfortunately, his suspicion rested on the mind glow of the two-leg, and although none of the others had actually said so, he knew they found it difficult to believe a two-leg's mind glow could tell one of the People so much. He even knew why they thought that way, for no other scout had ever come close enough to — or concentrated hard enough upon — a two-leg to realize how wonderfully, dreadfully powerful that mind glow truly was.

"I believe that you believe the two-leg had some way of knowing you were there," Short Tail had told him judiciously, his mind voice grave, "yet I fail to see how it could have. You saw none of the strange lights or tool things the two-legs have used to detect other scouts, after all."

"True," Climbs Quickly had replied as honestly as possible, "yet the two-legs are very clever. I saw none of the tool things I knew to look for, but does that prove the two-legs have no tool things we have not yet learned of?"

"You hunt for ground runners in the upper branches, little brother," Broken Tooth, the most senior of Bright Water's elders, had put in sternly. "You allowed the two-leg not simply to see you but to see you raiding its range. I do not doubt you tasted its mind glow, but neither do I doubt that you tasted within that mind glow that which it was most important for you to taste."

Much as Broken Tooth's charge had angered Climbs Quickly, he'd been unable to counter it effectively. The feelings of the mind glow were always much easier to misinterpret, even among the People, than thoughts which were formed into words, and it was only reasonable for Broken Tooth, who'd never tasted a two-leg mind glow, to assume that it would be even more difficult to interpret those of a totally different creature. Climbs Quickly knew — didn't think; knew — that the two-leg's mind glow had been so strong, so vibrant, that he literally could not have read it wrongly, yet when he couldn't explain how he knew that even to himself, he could hardly blame the clan's leaders for failing to grasp the same fact.

And so, because he couldn't explain, he'd accepted his scolding as meekly as possible. The cluster stalk he'd brought home had muted that scolding to some extent, for it had proved just as marvelous as the songs from other clans had indicated, but not even that had been enough to deflect the one consequence he truly resented.

He had been relieved of his responsibility to watch over his two-legs, and Shadow Hider, another scout (who just happened to be a grandson of Broken Tooth), had been assigned that task in his place. He understood why, however much he disliked it, for the People had only to watch them cutting down trees with their whining tools that ate through the trunks of trees large enough to hold whole clans of the People or using the machines that gouged out the deep holes in which they planted their living places to recognize the potential danger the two-legs represented. They need not decide to kill the People or destroy a clan's entire range to accomplish the same end by accident, and so the People had decided that their only true safety lay in avoiding them entirely. The clans must stay undetected, observing without being observed, until they decided how best to respond to the strange creatures who so confidently and competently reshaped the world.

Unfortunately, Climbs Quickly had come to doubt the wisdom of that policy. Certainly caution was necessary, yet it seemed to him that many People — such as Broken Tooth and his like among the other clans — had become too aware of the potential danger and too un aware of the possible advantages the two-legs presented. Perhaps without even realizing it, they had decided deep down inside that the time for the two-legs to learn of the People's existence would never come, for only thus could the People be safe.
