Despite the overwhelmingly positive reaction of the Sphinxian human population to their arboreal neighbors, Scott could think of several unpleasant reasons why a treecat might be afraid of people, given the history of human race relations, even amongst its own species. While the colonists were, on the whole, good people, there were always troublesome, unpleasant individuals in any population and there had been occasional grumbles about sectioning off large parcels of previously choice real estate as sacrosanct treecat preserves.

None of the darker thoughts occurring to Scott as they hiked deeper into the forest inspired any confidence that this trek would have a happy outcome. So he gripped his rifle, watched and listened for any sign of hexapumas or peak bears, and tracked the passage of time as the sun lowered gradually toward the treeline. By the time the one-hour limit expired, Scott was flagging behind Aleksandr, an increasingly footsore hiker. He wasn't wearing his hiking boots and civilian shoes weren't manufactured with Sphinxian picket wood systems in mind. He was more than ready to turn back. As his watch alarm sounded, he called a weary halt and shut it off.

"That's an hour," he said, unnecessarily.

The treecats burst into a frenzy of bleeking, racing along the horizontal picket wood branches overhead to dance agitatedly just above them, then turning and racing back in the direction in which they'd been moving steadily. The urgency he was picking up from Fisher increased at least threefold. He also received the distinct feeling they were very close to whatever it was the emaciated treecat wanted them to see.

"Five minutes," he agreed reluctantly. "Five minutes, then we turn back."

"Bleek! Bleek, bleek, bleek!"

Fifteen-year-old Karl Zivonik grinned. "Five minutes, huh? Just how hard is it to say `no' to a treecat, Dr. MacDallan?"

"Watch yourself, youngster," Scotty smiled, "or one of these days some pretty little lady treecat might decide you're exactly what she's looking for—and then you'll find out!"

The boy's eyes went round. "Really? Do you think I might ever get adopted?"

Scott chuckled, then slapped the youngster's shoulder. "Frankly, I have no idea. The treecats can't share their criteria for picking friends, after all, since they can't talk to us."

"Have any girl 'cats adopted anyone?"

Scott frowned slowly. "That's an interesting question, Karl. Come to think of it, I haven't heard of any. I'll have to check it out. Maybe the xenology team that arrived to study them will know."

They forded a shallow creek, work boots and Scott's low-topped shoes squelching in the mud, and climbed the opposite bank, heading deeper into a thick tangle of picket wood trunks. A couple of minutes later, Scott noticed an increase in the light falling through the canopy, a familiar sort of increase he'd noticed several times before while hiking to a promising fishing site, where occasional natural clearings in the forest allowed in more light. Such clearings often marked the presence of small lakes or old forest-fire scars or a change in topography or soils that discouraged picket wood growth. Another minute later, they rounded a thick tree bole and emerged at the edge of a small clearing, just as he'd surmised they would. But when he got a good look at that clearing, Scott rocked to a halt. So did the Zivoniks.

It was not a natural clearing. A ragged hole had been forcibly torn through the forest canopy, leaving a debris trail ninety meters long. Something large and man-made had plowed through the tangle of branches and upper-level trunks with massive, splintering force on its way to the forest floor. Bits and ribbons of metal lay in torn, jagged shreds in a path arcing downward along the trail of broken branches and clipped trunks. More metal fragments had embedded themselves in unbroken trees on either side of the path of devastation, where the force of impact had flung them. Scott's gaze followed the trail of ruin down and to their left, aware of a sick tension in his muscles as he sought what he knew he must inevitably find.

And there it was, nearly a dozen meters to their left. A massive cargo carrier had come down at what must have been a terrific rate of speed. The hulk had finally smashed against a picket wood trunk too thick to snap off, about two meters above the forest floor. The metal frame had crumpled like fragile tissue paper around the picket wood, then slammed down to the forest floor at an insane, twisted angle, a complete ruin.

Scott swallowed hard.

How many people had died, inside?

The treecats uttered shrill, sharp sounds and raced away through the tangled, broken branches, making for the wreck. Scott caught Aleksandr's glance. He considered suggesting that Karl stay behind, then thought better. The Zivoniks were pioneering folk, farming a hundred klicks from their nearest neighbor. Sheltering the boy wouldn't do him any favors. Colonists needed tough hides. The look in Alek's eyes told him the same thoughts had gone through the farmer's mind, as well. Aleksandr nodded sharply, then broke trail through the ruin of debris and splintered trees. Young Karl said nothing and looked rather pale, but followed his father without pause. The medical pack Scott had strapped on before leaving the farmhouse felt useless, a superfluous gesture in the face of violent death.

They climbed over fallen limbs and shattered tree trunks until they reached the wreck, then Aleksandr said, "Let's see how stable she is before we go looking for the hatch."

Scott nodded. The big farmer studied the way she lay, looked at the broken tree limbs under the hull where she'd dug partway into the ground, then shoved at the battered airframe and hung his full weight from it. She was wedged in solid as a mountain, from the look of things. As they hunted across the twisted hull for the access hatch to the pilot's compartment, Scott dreaded the sight which awaited them. He found a vaguely familiar, battered logo on a badly dented section of hull, a stylized picket wood tree with its trunk formed from the double-helix spiral of a DNA molecule. The paint was so badly scraped, the name had been completely obliterated, leaving only about half of the double-helix tree. Aleksandr Zivonik noticed him peering at it and looked over his shoulder.

"That's a BioNeering company logo," the farmer said quietly. "They've got a research plant out here somewhere, but it's a long way from our farm."

"I thought I recognized the logo, I just couldn't place it."

Overhead, the treecats emitted a sharp whistling sound and jumped down onto the uptilted end of the wreck, scampering across the side to pause halfway down.

"Looks like they found the way in," Karl said nervously. The boy was swallowing hard.

"I begin to suspect," Scott said slowly, "that the stray 'cat knew whoever was inside." He couldn't imagine any other reason for the treecat to behave in such an agitated fashion, or for the 'cat to have been in such a wretched state. Had the stray adopted the pilot, perhaps, and been left behind when the air car took off for its cargo run? Just how long had the air car been down? It would take days to run that much weight off a treecat. The thought of Fisher struggling across miles of wilderness trying to reach him brought a thickness to his throat. Scott started to climb cautiously up the dented, twisted hull and found, not the hatchway, but the shattered windows of the pilot's compartment.

One look and Scott swallowed sharply. It was not difficult to determine where the blood all over the treecat's fur had come from. The pilot's compartment had been awash with it, before the spatters and puddles had dried to a rusty brown scum.

"The hatch is back here," Aleksandr said off to Scott's right. "The frame's bent pretty badly around it, but the latches popped under impact." Bending metal shrieked in the unnatural stillness, a desecration that couldn't be avoided. Scott edged his way around to help pry it further open. The hatch shrieked in protest, but finally gave way. Scott ducked through first. The stench of decaying flesh gagged him. He paused to cough and wipe his mouth, then fumbled for a mask from his surgical kit to tie around his mouth and nose. Wordlessly, he handed masks to the Zivoniks. The control compartment was a fraction of its original size. Judging from the debris, there'd been three people inside when she'd impacted. Pilot and co-pilot, probably, maybe a company executive or an employee headed to or from that remote plant Alek had mentioned.
