"I don't know who," he said in a quiet, hard voice, speaking directly to the pine-green eyes of the female 'cat, "and I don't know how. But I will, by God, find out. However you did it, thank you for telling me."

He turned and stalked away through the smothering darkness, aware of rustlings in the branches overhead as the assembled treecats escorted him back to the bright lights at the edge of the crash clearing. He had to be careful, he knew that; with a situation as potentially volatile as this, treecats involving themselves in a spectacular triple murder in the human community, with God-only-knew what ramifications for the future of relations between the two species, he had to move with extreme circumspection until he had proof. He couldn't just blurt out his suspicions. Not only did he have to gather proof that would convince the Manticoran authorities, he had to present something concrete, rather than nebulous feelings received from treecats. And he certainly couldn't admit to having received the message through a psychic flash of intuitive suspicions and images obtained through mindreading. He'd be laughed straight off Sphinx. Or worse.

Even the most open-minded humans understood so little about their new neighbors, the idea of a treecat communicating such a thing as murder or a cover-up scheme to hide a major industrial accident—through clairvoyance, no less—would likely trigger everything from open skepticism to outright hostility to blatant panic. He knew he was right; but very few humans had spent anything close to a T-year coming to understand the nuances of the strange bond which existed between a human and the treecat which adopted him or her.

So he would have to proceed with extreme caution, nudging the crash team in the direction he wanted their investigation to go, gathering evidence on BioNeering's activities on his own in his official capacity as coroner for these fatalities. Thank God he'd had the foresight to ask Mayor Sapristos to make that official before he got started out here. But he couldn't even go to Sapristos until he had something concrete that didn't involve saying, "Well, sir, the treecats told me so" when everyone knew the treecats couldn't tell anyone anything, not directly, and he couldn't, wouldn't, risk telling the truth about his own personal, psychic secret.

Had it taken the combined empathic skills or telepathy or whatever they used, of that many treecats, massed for one single-minded effort, to get those few brief images and emotions across to him? Or had they realized there was something in his Scottish heritage that made him more receptive to whatever it was the treecats used to communicate? Treecats couldn't know the old Earth legends about the Scots and Irish being "fey," legends which still persisted, despite the complete lack of ability to measure such a thing, but they could certainly pick up human emotions and broadcast their own, at least to Scott.

The notion that the 'cats had somehow known that only Scott MacDallan would be able to understand their message left him more determined than ever to get to the bottom of this mystery—and to do it without jeopardizing the treecats' future by giving away too much information about them. At least, not before the humans on Sphinx could be convinced or coerced into establishing proper, civilized diplomatic relations that protected their little neighbors.

Whether or not the treecats had chosen him deliberately because of his genetic heritage, he couldn't be sure, and doubted that he or anyone else would ever know that particular truth; but he could certainly start finding answers to the questions posed by this crash. And he intended to begin with the air car itself, try to find out exactly what had caused that big cargo car to come down, not just assume it'd been downed by the storm. Just before he stepped out from beneath the last trees, he felt a familiar weight settle onto his shoulder and welcomed Fisher with a gentle hand. Then another weight dropped to his other shoulder and Scott found himself gazing into the brilliant grass-green eyes of his determined stray.

"Bleek!" It pointed toward the waiting crash team with stark emphasis.

"Oh, yes," Scott agreed softly. "We will, indeed!"

He broke cover into the clearing and rounded the bow of the misshapen wreck.

"Vollney! Keegan!"

The crash investigators appeared from two directions, one leaning out the open cargo hatch, the other jogging around the crumpled stern. "Doc?"

"There's something bothering me about this crash. I've flown through thunderstorms dozens of times, trying to get to patients who needed a doctor, flew through one with a concussion, once, to get my friend, Fisher, here, and myself to a hospital. I don't know exactly what we're looking for, but whatever it is, it caused this air car to go off course several hundred kilometers and crash without sending out a distress call or beacon signal. I can't believe an experienced pilot caught in a thunderstorm wouldn't com his position or turn on his emergency transponder, at the very least. What've you found so far? Was their equipment damaged by lightning strikes, maybe, that prevented them from calling for help?"

Nick Vollney and Marcus Keegan exchanged startled glances. Then Vollney said, "Uh, now you mention it, Doc, I haven't seen the kind of damage you'd expect from a lightning strike to their instrumentation. There's no characteristic popcorn denting from hailstones on the hull, either, although that's not definitive, since there are plenty of thunderstorms that don't produce low-atmosphere hail. But you've got something with the instruments, Doc, we've just been assuming the storm prevented them from calling out or setting their beacon, without really checking out how or why. I'll get right on it."

Keegan added, "If it wasn't lightning, maybe a violent downdraft while they were at low level sent them into the canopy? But that'd mean their anti-gravs were malfunctioning and I didn't even check those." He frowned. "This may take a while."

Scott grimaced. "I may be tired, Marcus, but I'd rather know what caused this crash. Get on it, would you?"

"Right." The investigator crawled into the remains of the battered air car.

Scott was tired, so much so he'd have been happy to curl up on a picket wood limb, if it'd offered a quiet place to sleep. Instead, he rolled up his sleeves and dug out his surgical kit and mask, and got busy in the cargo hold of the rescue air car. He had three field autopsies to perform and the night wasn't getting any younger. The possibility that the killer had somehow drugged the victims was too great to ignore and might explain why they were so far off course and hadn't called in their difficulty. Unconscious or incoherent pilots wouldn't have been able to keep their car on course when the storm that must have masked the sounds of the crash from the Zivonik homestead had caught them somewhere between BioNeering's research facility and town.

Pine-green eyes burned in his memory as he set to work. At his side, a starvation-thin treecat watched as Scott began the grisly work of cutting open the remains of the poor stray's murdered friend. A stab of rage tore through him. This time it was all his own. The treecats were counting on him to prove that what he gazed at right now was murder.

Scott did not intend to let them down.

Dawn was breaking over the Zivonik farmhouse when the air car settled in the broad sweep of grass beyond the kitchen garden. Scott reeled out, eyes bleary from lack of sleep, and stumbled beside Aleksandr Zivonik and his oldest boy toward the house. All Scott wanted was a mattress under him and a long, hot soak in gallons and gallons of steaming water. The Zivonik children, blinking sleepily, met them at the door. Irina Kisaevna appeared a moment later as they approached, looking gloriously tumbled from sleep and wholesome enough to drive away the stink of horror clinging to his very skin.
