"This way, Doctor," Holloway said, pointing toward the copilot. "Crane, you go with Bremmer. Find some cover and dig in. Stay off the comm—the Conquerors like to track radios. Whistles and hand signals only."

"Right."

Holloway and Melinda reached the edge of the trees the same time as the copilot. "That looks good over there," Holloway said, pointing to a low rock formation. "Wei, how's the ankle?"

"Not too bad, Colonel," the copilot said, his voice soft and polite. "I don't think it's broken."

"We'll find out soon enough," Holloway said, taking his arm and helping him to the cover of the rock. "Did you get a Mayday out before we hit?"

"Yes, sir," Wei said, wincing as he sat down on the ground. "But there was no response. We're still eight klicks out—they probably didn't pick us up."

"One of the other aircars might have, though," Holloway said, unslinging his assault gun. "Check his ankle, Doctor. No, hold it—let me get your suit going first."

Melinda held still as he reached under her serape and slid a switch forward on her belt. Faintly, from the hood, she heard a gentle hissing. "What's that?" she asked.

"Liquid nitrogen from the belt tanks," he said, reaching under his own serape. "Works with the reflective layering to erase your infrared signature. Here's the other half of the mirage," he added, pulling a fat disk from under his serape. Working his right arm free from the serape, he clicked a switch on the disk and threw it through the trees to land about twenty meters away from them, roughly opposite the aircar's nose. "If the thing works—for a change—it should now look more like a human being than we do."

"Of course, it's all a waste of time if they don't have IR detectors," Wei pointed out. "Or don't know what a human signature looks like."

"We can but try," Holloway agreed. "Okay, Doctor, go ahead and check his ankle."

Carefully, Melinda got Wei's boot off, feeling a drop of sweat trickle down the middle of her back despite the cooling effect of the serape against it. She was a doctor, certainly, and had had the whole spectrum of medical training. But theory and simulation work were a far cry from working on living patients. What actual surgery she'd done was years in her past, and she wasn't at all sure how well she was going to be able to dust off those skills.

But for the moment, at least, it wasn't a challenge she had to face. "It's just a sprain," she assured Wei, opening the first-aid kit and digging out a pressure bandage. "It should be all right in a few—"

"Quiet," Holloway cut her off. "Something's coming."

Melinda froze, listening. In the distance she could hear a faint humming sound. "One of ours?" she whispered.

"Doesn't sound like it," Holloway said grimly, working a pair of slides on his assault gun. "Wei, signal Bremmer and Crane to get ready."

"Yes, sir," Wei said, digging a slender tube from his tunic pocket and looping the attached chain around his neck. Lifting the tube to his lips, he blew three short oddly pitched trills and then one long one. The answer came immediately: one long and one short.

"I think I see them," Holloway said, peering up through the trees. "Cavanagh, get as much of you under your serape as you can and stay put."

Melinda hunched down behind the edge of the rock formation, pulling her legs up beneath the edge of the serape and tightening the hood a little closer around her face. The humming was getting louder, and she caught a flicker of something white as it shot past a gap in the tree canopy above. Clenching her teeth, she braced herself—

And suddenly it was there, swooping across the gap gouged by the crashing aircar: a milky-white dragonfly-like vehicle, topped with a circular haze of whirling rotors. It made a tight loop around the crushed nose of the aircar and then moved around behind it. For a moment it hovered there, sending up a cloud of dust from the freshly turned earth, swiveling its nose gently back and forth as if deliberately inviting anyone nearby to attack. Melinda tensed, but the Peacekeepers held their fire, and a minute later the ship settled to the ground. On both sides doors popped open.

And from them two aliens stepped out.

Melinda squinted across the dusty clearing, her fear momentarily forgotten in sudden clinical interest. The aliens were like nothing she'd ever seen before: roughly human in height, with slender bipedal builds and thin, narrow heads that extended well behind them. Good cranial capacity, with enough brain size for mental capability plus strong manipulative control. They were too far away for her to get a good look at the hands, but from the way they gripped the gray sticks they were holding, they clearly had opposable thumbs. Possibly two per hand, in fact. They had tails, too, short flat things that extended from low dorsal ridges just above the juncture of the legs and continually twirled around in a corkscrewing motion that reminded her of a water creature she'd seen once. A heat radiator, possibly, or perhaps some sort of atmospheric sampler like those in snake tongues. One of the aliens turned in her direction, giving her a clear view of a triangular face, deep-set eyes beneath brow ridges, and a pointed snout reminiscent of a bird's beak. They walked slightly bent forward, their feet appearing to have something of the same splayfooted design of seagull feet except without any webbing between the toes.

"Colonel?" Wei whispered urgently.

"Hold your fire," Holloway murmured. "Maybe they'll be happy with wrecking the aircar and go away."

Melinda swallowed, jolted back to the deadly realities of the situation. These weren't just a new species of self-starfaring aliens come here for her to examine.

These were the Conquerors. They were here to kill.

Four more of the aliens had joined the first two, the newcomers waiting beside the craft as the first pair picked their way across the rubble to the side of the aircar. They looked inside, and through the pulsating wind from the rotors Melinda could hear them saying something. An amplified voice answered back. "Well, they know we got out," Holloway murmured beside her. "Let's see how badly they want to find us."

The answer was quick and decisive. Within a few seconds the vehicle had lifted smoothly back into the sky, rising ten meters before coming to a halt. Fanning out, the six Conquerors on the ground started toward the trees where Holloway had thrown the decoy disk.

"Shouldn't we open fire?" Wei asked tensely, his knuckles tight where he gripped his assault gun.

"All in good time," Holloway told him, squinting upward at the hovering vehicle. "You and I will try to take out the copter. Set for full antiarmor, then whistle Crane and Bremmer that they're to hit the ground troops when we open fire."

"Yes, sir," Wei said, lifting his whistle and launching into a short series of blasts.

The Conquerors stopped, dropping down into half-crouched stances, their heads darting back and forth as they searched for the source of the sound. Melinda tensed, but the odd pitch of the whistle seemed to defeat their efforts to locate it. Wei finished his message, and for a moment the Conquerors remained where they were—again, Melinda thought, almost as if deliberately inviting attack. But again Holloway held his fire, and after a moment they straightened up and continued their cautious march toward the trees.

"Sir?" Wei hissed nervously.

"Get ready," Holloway said. He threw a glance at Melinda, and she was struck by the underlying calmness in his face. "Brace yourself, Doctor; this is going to be noisy. Wei, on zero. Three, two, one, zero."

The two assault guns erupted in unison, shattering the quiet of the forest with the vicious stutter-bark of explosive shells cycled together with what sounded like small missiles. An instant later the sound was echoed from across the woods as the other Peacekeepers and civilians opened fire.
