about that," Natalya interjected.
"It's useful, but it's only completely effective when you're standing still. There's a finite time gap between the sensors picking up the background and the microcircuits reproducing it." With a slightly playful expression, she spoke a few syllables of what Sarnac assumed was Raehaniv. Suddenly her head and hands floated in midair with no seated body beneath. Then the hands fumbled with the hood behind her neck, and the head vanished as well.
I will not gape like a yokel! Sarnac told himself firmly. He stole a glance at Natalya. She was wearing an expression of grimly determined nonchalance.
Natalya and Sarnac heard more Raehaniv, and Tiraena reappeared, pulling back the hood. "My suit was very expensive," she continued. "It was issued to me in case I found myself in a situation like this one."
"Well, now that you're in it, what do you plan to do?" Sarnac asked.
"Continue down the river to the coast and make contact with the Raehanvoihiv in that area. I can—"
"With the what?" Natalya asked.
"Oh . . . the native sentients. We call this planet Raehanvoi—New Raehan. The culture around the estuary carries on a limited coasting trade with other high-neolithic groups to the south. We can travel concealed on one of their large sailing rafts, and once we reach the southerners' region it will be only a short trip to the base. Even if we don't get all the way there, we'll be in concealment while we await the arrival of the relief fleet."
"Maybe we won't have to wait that long," Sarnac said truculently. "Ever consider the possibility that our squadron may whip the Korvaasha and come back for us?"
"It would be unwise to invest much hope in that. The Korvaash force in this system has a prohibitive advantage in tonnage, and we've seen nothing to indicate that you possess any significant technological advantage." She seemed to realize that she might have been just a mite tactless, and continued in what Sarnac thought probably represented her best effort at a conciliatory tone. "But don't worry. Our fleet will be arriving eventually. In the meantime you are welcome to accompany me to the base. You'll be a sensation: people from the lost homeworld we've been searching for for two centuries!
"But for now," she continued, rising to her feet, "we'd better get some sleep. Your friend will be able to travel in the morning, and we'll want to cover as much ground as possible."
"Wait a minute!" Natalya was almost plaintive. "You can't stop now! You still haven't said anything about the fact—which you asked us to accept, even though it's patently absurd—that homo sapiens could have evolved independently on another planet, this Raehan."
"I never said anything about independent evolution, Lieutenant Liu. The human race did, in fact, evolve on Earth. Its presence on Raehan dates back about thirty thousand of your years."
I really wish she'd stop saying things like that , Sarnac thought, too numb to feel more than mild irritation with this impossible woman for continuously kicking the foundations out from under his intellectual universe. Aloud: "Uh, Tiraena, do you mean . . ."
"I do. And to answer your next question, we have no idea how our original Raehaniv ancestors—Palaeolithic savages like their Terran contemporaries—got to Raehan." Her face wore an odd little smile. "We're completely in the dark about it, Lieutenant Sarnac. And now your people will join us in that darkness."
Tiraena had a skullcap-like device which granted its wearer electromagnetically induced sleep for any preset period. Sarnac envied her, for sleep would not come to him under the alien stars.
Chapter Four
They were following what was clearly a well-used trail when they met the Danuans.
"Let me handle this," Tiraena said. "We've had dealings with this culture before. My translator is programmed with the trade language. I'm afraid the language of the islanders you met isn't even related." She stepped forward,
