a helicopter had emerged from the black pyramid - but it was unlike any machine ever created on earth. Instead of rotors, triangular metallic wings like those of a giant dragonfly beat rapidly along the sleek black body. Its cockpit - the shape an exact duplicate of the compartment in which Taggart, Rhodes, and Gunniston sat - was made of what appeared to be blue-green, opaque glass, multifaceted like the eye of an insect. Most startling of all, and what had caused Taggart to grip the throttle and veer away so fast, was the craft's tail section: it was made of intertwined, ropy black muscles, and at its end was a bony ball of spikes like a knight's mace. The tail was whipping violently back and forth, the muscles alternately clenching and relaxing.

"a doppelganger," Rhodes said.

Taggart was concentrating on working the cyclic control stick with his right hand and the twistgrip throttle with his left, backing the 'copter away without crashing into the bank building or drifting into the grid. Smoke swirled in front of the cockpit. The dragonfly machine held its position, but slowly angled as if its insect eye was following the earth craft. Gunniston said, "Whati" "a doppelganger," Rhodes repeated, thinking aloud. "a mirror image. at least... maybe that's how an alien sees us." another thought struck him. "My God... there must be a factory in there!" But was it a machine, or was it alivei It was a double of their own helicopter, yes, but the way those wings and muscles worked, the thing might be a living creature - or more bizarre still, a combination of machine and alien life. Whatever it was, the sight held Rhodes in a thrall of horrified wonder.

The trance snapped, very suddenly, when the dragonfly darted forward, soundlessly and with a deadly grace.

"Go!" Rhodes shouted, but the breath was wasted. Taggart's hand on the throttle made the engine scream. The helicopter shot backward and up, missing the overhanging ledge of the bank building's roof by about eight feet. Gunniston's face was a bleached-out shock mask, and he gripped the armrests of his seat like a cat on a roller coaster. The dragonfly made a quick, twitching correction of flight, angled up, and came after them.

The 'copter rose into clouds of smoke and dust. Taggart was flying blind; he eased off on the throttle and spun the machine in a tight circle, the engine spitting through dirty air. as Taggart made the second rotation Gunniston yelled, "at starboard!" The dragonfly plunged through the murk on their right, twisted violently around in imitation of their own maneuver, and the tail with its ball of spikes came at them. Taggart jerked the 'copter to the left; as the machine heeled over, the dragonfly's tail flashed past so close both Rhodes and Gunniston could see the razor-sharp edges of the spikes. Then clouds enveloped it, and as the 'copter kept falling Rhodes realized that a few blows from that damned tail could tear the aircraft to pieces. He didn't care to think about what it would do to flesh. Taggart let the helicopter plummet until his stomach lurched, and as they dropped through the clouds and leveled off he saw the houses of Bordertown about sixty feet below, people standing in the streets and the glow of candles through windows. He made another tight turn, zooming over the autoyard - and there was the dragonfly, emerging from the clouds and gaining speed at it hurtled at them.

"Head for the desert!" Rhodes said. Taggart nodded, his face sparkling with sweat, and gunned the throttle. as soon as the helicopter leapt forward, the dragonfly changed direction and maneuvered in front of them, cutting them off. "Dammit!" Taggart said, and altered course. The dragonfly did too. "Bastard's playing games with us!" "Get us on the ground!" Gunniston pleaded. "Jesus Christ, set us down!" The dragonfly pitched downward, came up again with terrifying speed at the helicopter's underbelly. Taggart had time only to rear the helicopter back on its tail rotor and pray.

In the next second came an impact that knocked the men breathless and rattled their brains. There was a shriek of tortured metal, even louder than Gunniston's scream. everything not bolted down in the cabin - flight log, pencils, extra helmets, and flight jackets - flew around their heads like bats. The cockpit's glass shattered into a crazy quilt, but the glass was reinforced with metal filaments and did not explode into their faces. acting on instinct, Taggart jerked the machine to the left again, the engine stuttering against a stall. The dragonfly swept upward and away, whirling around and around in a deadly pirouette, bits of the helicopter's metal flying off its tail like miniature comets.

The red landing-gear malfunction light blinked on the instrument panel, and Rhodes knew the skids were either mangled or torn away. "Clipped our skids!" Taggart shouted, panic starting to close around his throat. "Bastard clipped us!" "Here it comes!" Gunniston had seen the thing through the unbroken window at his side. "at three o'clock!" he yelled.

Taggart felt the helicopter's blades respond to the stick, and the machine swung up as his feet worked the tail rotor pedals. They were on an even keel again, and he laid on the throttle and arrowed straight for the desert to the east of Inferno.

"It's closing!" Gunniston warned, daring to look back through the rear observation port. "The thing's hauling ass!" Rhodes saw the low-fuel warning light come on. The airspeed indicator was nosing toward a hundred and twenty, violet-washed desert flashing past about ninety feet below and the grid's eastern boundary in sight. Gunniston made a choked sound of terror as the dragonfly pulled up even with them at a distance of twenty or thirty yards to the right, its triangular wings a whirring blur. It hung there for about five seconds before it darted ahead, rapidly gained altitude, and vanished into the haze at the top of the grid.

Taggart could no longer see it through the cracked glass. He whipped the 'copter around in a spiraling turn that shoved Rhodes and Gunniston into their seats and dropped twenty feet lower to the desert, speeding back in the direction of Inferno. "Where is iti Where'd the bastard goi" he babbled. "You see it, Colonel." "No. Gunnyi" Gunniston could hardly speak. He got out a weak "No, sir." Taggart had to cut his speed before the reserve fuel drained. The speed-indicator needle trembled at sixty. "She's handling like a tractor!" Taggart said. "Must have a mess hanging down underneath! Damn sonofabitch just pulled away like we were sitting still!" air was shrilling in through the cockpit's cracks, the control stick was sluggish, and they were flying on fumes. "I've got to set her down!" Taggart decided. "Gotta belly her in, Colonel!" They were almost over Inferno again. "Clear the town first!" Rhodes said. "Slide her in on the other si - " "Jesus!" Taggart screamed, because the dragonfly was dropping down from above, almost on top of them, and for an instant he thought he could see a distorted image of himself - an alien image - reflected in the multifaceted glass. He turned the 'copter over on its right side, trying to whip past - but the thing was too close, and its tail was swiping toward him. He drew a breath.

The tail smashed through the cockpit's glass, filling the compartment with a thousand stinging hornets. Fragments slashed into Rhodes's cheeks and forehead, but he'd flung his arms up and saved his eyes. He saw what happened to Taggart.

The spikes on the end of the tail buried themselves in Taggart's chest. His head, left arm, and most of the upper half of his torso disappeared in a blizzard of blood, metallic sparks, and flying glass. The dragonfly's tail continued through the pilot's backrest like a can opener, and Gunniston saw the clenching ebony muscles and the ball of spikes pass him with the velocity of a freight train before it tore through the 'copter's side and out again. He laughed hysterically, his face covered with Taggart's blood.

Irrevocably damaged, the helicopter reeled across the sky. It spun in a wide, fast circle, and through the broken glass Rhodes dazedly watched as the north face of the bank building grew larger.

He couldn't move. Couldn't think. Somebody's blood was everywhere. There was a lump in the pilot's seat that had no business being there, yet clenched to the control stick was a gray hand that should belong to someone. Red lights flashed all over the instrument panel and alarms buzzed. The roofs of Inferno were coming up fast, and Rhodes had the eerie sense of sitting still while the world and the wind were in terrifying motion. The bank building loomed ahead. We're going to crash, he thought calmly. He heard laughter, and its incongruous sound amid all the carnage made the slipping gears of his brain latch into place again. Within seconds they would smash into the bank building.

Rhodes reached for the pilot's control stick, but the gray hand was locked on it and the dead arm's muscles had seized up; the stick was immobile. He blinked, saw the copilot's stick in front of his own seat, a twistgrip throttle to the right. He grasped the stick. No reaction from the rotors. Dead controls, he thought. No, no... the transfer switch... Rhodes reached over Taggert's corpse and hit the controls-transfer toggle on the instrument panel. The warning lights lit up on his side. He hadn't flown a helicopter for more than two years, but there was no time for a checkout course; he slipped his feet onto the pedals that operated the rear rotor and angled the control stick with his left hand, at the same time cutting the speed with his right. The building stood before him like a mountain, and even as the 'copter responded to a tight turn Rhodes knew there wasn't going to be enough room. "Hold on!" he shouted to Gunny.

as the 'copter swerved, its tail rotor smashed one of the few remaining windows on the building's second floor and chopped a desk to kindling. The main rotors scraped bricks and threw off a shower of sparks, and as the tail rotor slammed against the wall there was a rupture of lubrication lines and fluids exploded into flame. The helicopter kept turning, all control gone and bucking like an enraged bronco.

Rhodes saw the dragonfly hurtling at them, its wings swept tightly back along its body and the spiked tail flailing. He twisted the throttle to full power; the 'copter shuddered violently, hung waiting to be crushed against the building.

There was a gasp like air being sucked into laboring lungs, and the 'copter dropped another twenty feet and lurched forward.

The dragonfly zoomed over Rhodes's head, hit the bank building, and smashed itself like an insect against a flyswatter. It crumpled with a wet splatting sound, and pieces of dark matter burst over the bricks. Rhodes was engulfed in a squall of amber fluid, and then the helicopter was stuttering through the rain of alien liquid and he saw Cobre Road rising up to take them.

The craft bellied onto the pavement, bounced and slammed down again, skidding along Cobre Road, past Preston Park and caroming off a parked brown pickup truck. It kept going about sixty more feet, its engine dead but its bent rotors still whirling, and stopped just short of the Smart Dollar's plate-glass window, where a red-lettered sign proclaimed GOING OUT OF BUSINeSS SaLe.

"Well," Rhodes heard himself say, just to verify that he was still alive. He couldn't think of anything else, so he said it again: "Well." But now he smelled burning oil and heard the crackling of flames at the tail rotor, and he knew the fuel tank was probably torn open and they'd better get their asses clear. He twisted around to make sure Gunniston was all right; the younger man was splattered with blood and amber juice, but his eyes were wide open and he wasn't laughing anymore. Rhodes said, "Let's go!" and unbuckled his seat belt. Gunny didn't react, so Rhodes popped the seat belt off him, took his arm, and jerked the hell out of him. "Let's go!" They clambered out. Rhodes saw four figures running toward them, and he shouted, "Stay back!" They obeyed, and Rhodes and Gunniston staggered away from the wreckage. about eight seconds later the 'copter's tail section exploded. a piece of metal the size of a pie pan shot through the Smart Dollar's window.

Three seconds after the first explosion, the helicopter went up in an orange blast, and more black smoke rose to join the clouds at the top of the grid.

Gunniston fell to the curb in front of the Paperback Kastle, and curled up into a shivering ball. Rhodes remained on his feet, watching the helicopter burn. The death of Taggart seemed unreal, something that had happened too quickly to apprehend. He looked at the bank building, could see the dragonfly's glittering slime oozing down the bricks; when he turned his attention to the black pyramid, he saw that the aperture had sealed itself.

"You sonofabitch," he whispered - and he thought that somewhere inside the pyramid a creature - or creatures - might be saying the same thing about him in the language of another world.

"I seen it!" said a leathery old man with white hair and a gold tooth, jabbering right in the colonel's face. "I seen it fly outta there, yessir!" a rotund woman in overalls prodded Gunniston's ribs with the toe of a tennis shoe. "Is he deadi" she asked. Gunniston suddenly sat up, and the woman leapt backward with the speed of a gymnast.

Other people were coming, drawn by the burning helicopter. Rhodes ran a hand through his hair - and then he was sitting down, his back against the rough stone of the Paperback Kastle's wall though he didn't remember his knees bending. He smelled Taggart's blood all over himself, and there was another, acidic odor too: it took him back to his youth in the green hills of South Dakota, and the image of catching grasshoppers on a sunny summer afternoon. He remembered the sharp tang of the nicotine-brown juice the grasshoppers sprayed on his fingers: hopper pee, he called it. Well, he was covered with it now, and the thought stirred a grim smile - but the smile faded very quickly as the memory of Taggart's body being ripped apart came back to him.

"Your bird's had it," the old coot observed sagely, and another gout of flame leapt from the charred machine.

"Give 'em room, dammit! Step back, now!" ed Vance pushed his way through the knot of gawkers. He'd trotted over from Celeste Street, and just that short distance had left him puffing and red-faced. He stopped when he saw the gore-covered Rhodes and Gunniston. "Holy Keerist!" He looked around for a couple of able-bodied men. "Hank! You and Billy come on and help me get 'em to the clinic!" "We're all right," Rhodes said. "Just cut up a little, that's all." He saw tiny bits of glass glittering in his forearms, and he figured he was going to have a long bout with a pair of tweezers. There was a gash on his chin and another across his forehead that felt wicked, but they would have to wait. "Our pilot didn't make it." He turned to Gunniston. "You okayi" "Yeah. Think so." Gunny had been protected from most of the glass by being behind the front seats, but there were several cuts in his hands and a sliver about two inches long was stuck in his left shoulder. He grasped it, yanked it out, and tossed it away.

Rhodes tried to stand, but his legs betrayed him. a younger man in a red-checked shirt helped him up, and Rhodes said, "I'm getting too old for this shit." "Yeah, and I'm agin' more every piss-cuttin' minute!" Vance had watched the aerial duel and had thought for sure that the helicopter was either going to slam into the houses of Inferno or hit the First Texas Bank. He glanced at the building, saw the ooze where the flying monstrosity had impacted, and he recalled the creature in Dodge Creech's skin peering out the window and saying I don't like that thing. "Listen, Colonel, we've got to talk. Like right now." Rhodes gingerly worked the kinked muscles in his arms. "I hope you'll understand when I say it'll have to wait." "No sir," Vance said. "Now." There was an urgency in the sheriff's voice that commanded his attention. "What is iti" "I think we'd best take a little walk down the street." Vance motioned for him to follow, and Rhodes limped on stiff legs along Cobre Road. The helicopter was still belching black smoke and red licks of flame, and Rhodes thought he could smell Jim Taggart's body burning. When they were beyond earshot of the crowd, Vance said, "I think I had myself one of them close encounters. about twenty minutes ago I met somebody who looked like Dodge Creech... only he didn't, and he sure as hell wasn't." Rhodes listened to the story without interrupting and shook off the shock that kept taking his mind back to the memory of a gray hand and arm and a mangled body. It was the living who were important now, and if the thing in the black pyramid could dig under the river and the houses of Inferno, it could come up wherever it pleased. Whatever it was, it had just turned this piece of Texas badland into a battleground.

"What the hell are we gonna doi" Vance asked at the end of his story.

"We sure can't run," Rhodes said quietly. "There's nowhere to run to." I de-sire to ex-it, he remembered Daufin saying, and how frantic she'd gotten when she'd understood there were no interstellar vehicles here. She'd begged to be taken away, and he hadn't done it; she must have known the other spaceship was after her. But for what reasoni and who - or what - was the thing that Daufin called Stingeri

He touched his chin and looked at the blood on his fingers. His beige knit shirt was a patchwork of bloodstains - mostly Taggart's. He felt all right, maybe a little weak-headed. No matter, he had to keep going and think about rest and stitches later. He said, "Take me to Creech's house."
