Tanner pushed ahead, cutting a diagonal by the green Sunset. Dust continued to fall about him, great clouds of it, and the sky was violet, then purple once more. Then the sun went down and the night came on, and the stars Were very faint points of light somewhere above it all. After a tinie the moon rose, and the half-face that it showed that night was the color of a glass of Chianti wine held before a candle.

He lit another cigarette and began to curse, slowly, softly, and without emotion.

They threaded their way amid heaps of rubble: rock, metal, fragments of machinery, the prow of a boat. A snake, as big around as a garbage can and dark green in the cast light, slithered across Tanner's path, and he braked the vehicle as it continued and continued and continued. Perhaps a hundred-twenty feet of snake passed by before Tanner removed his foot from the brake and touched gently upon the gas pedal once again.

Glancing at the left-hand screen, which held an infrared version of the view to the left, it seemed that he saw two eyes glowing within the shadow of a heap of girders and masonry. Tanner kept one hand near the firecontrol button and did not move it for a distance of several miles.

There were no windows in the vehicle, only screens which reflected views in every direction, including straight up and the ground beneath the car. Tanner sat within an illuminated box which shielded him against radiation. The "car" that he drove had eight heavily treaded tires and was thirty-two feet in length. It mounted eight fifty-caliber automatic guns and four grenade-throwers. It carried thirty armor-piercing rockets which could be discharged straight ahead or at any elevation up to forty degrees from the plane. Each of the four sides, as well as the roof of the vehicle, housed a flamethrower. Razor-sharp "wings" of tempered steel, eighteen inches wide at their bases and tapering to points, an inch and a quarter thick where they ridged, could be moved through a complete hundred-eighty-degree arc along the sides of the car and parallel to the ground, at a height of two feet and eight inches. When standing at a right angle to the body of the vehicle, eight feet to the rear of the front bumper, they extended out to a distance of six feet on either side of the car. They could be couched like lances for a charge. They could be held but slightly out from the sides for purposes of slashing whatever was sideswiped. The car was bulletproof, air-conditioned, and had its own food locker and sanitation facilities. A long-barreled .357 Magnum was held by a clip on the door near the driver's left hand. A 30.06, a .45-caliber automatic, and six hand grenades occupied the rack immediately above the front seat.

But Tanner kept his own counsel, in the form of a long, slim SS dagger inside his right boot.

He removed his gloves and wiped his palms on the knees of his denims. The pierced heart that was tattooed on the back of his right hand was red in the light from the dashboard. The knife that went through it was dark blue, and his first name was tattooed in the same color beneath it, one letter on each knuckle, beginning with that at the base of his little finger.

He opened and explored the two near compartments but could find no cigars. So he crushed out his cigarette on the floor and lit another.

The forward screen showed vegetation, and he slowed. He tried using the radio but couldn't tell whether anyone heard him, receiving only static in reply.

He stared ahead and up. He halted once again.

He turned his forward lights up to full intensity and studied the situation.

A heavy wall of thorn bushes stood before him, reaching to a height of perhaps twelve feet. It swept on to his right and off to his left, vanishing out of sight in both directions. How dense, how deep it might be, he could not tell. It had not been there a few years before.

He moved forward slowly and activated the flamethrowers. In the rearview screen, he could see that the other vehicles had halted a hundred yards behind him and dimmed their lights.

He drove till he could go no farther, then pressed the button for the forward flame.

It shot forth, a tongue of fire, licking fifty feet into the bramble He held it for five seconds and withdrew it. Then he extended it a second time and backed away quickly as the flames caught.

Beginning with a tiny glow they worked their way up. ward and spread slowly to the right and the left. Ther they grew in size and brightness.

As Tanner backed away, he had to dim his screen, foi they'd spread fifty feet before he'd backed more than hundred, and they leaped thirty and forty feet into the air.

The blaze widened, to a hundred feet, two, three... As Tanner backed away, he could see a river of fire flowing off into the distance, and the night was brighi about him.

He watched it burn, until it seemed that he looked upon a molten sea. Then he searched the refrigerator, but there was no beer. He opened a soft drink and sipped it while he watched the burning. After about ten minutes the air-conditioner whined and shook itself to life. Hordes of dark, four-footed creatures, the size of rats or cats, fled from the inferno, their coats smoldering. They flowed by. At one point they covered his forward screen, and he could hear the scratching of their claws upon the fenders and the roof.

He switched off the lights and killed the engine, tossed the empty can into the waste box. He pushed the "Recline" button on the side of the seat, leaned back, and closed his eyes.

He was awakened by the blowing of horns. It was still night, and the panel clock showed him that he had slept for a little over three hours.

He stretched, sat up, adjusted the seat. The other cars had moved up, and one stood to either side of him. He leaned on his own horn twice and started his engine. He switched on the forward lights and considered the prospect before him as he drew on his gloves.

Smoke still rose from the blackened field, and far off to his right there was a glow, as if the fire still continued somewhere in the distance. They were in the place that had once been known as Nevada.

He rubbed his eyes and scratched his nose, then blew the horn once and engaged the gears.

He moved forward slowly. The burned-out area seemed fairly level, and his tires were thick.

He entered the black field, and his screens were immediately obscured by the rush of ashes and smoke which rose on all sides.

He continued, hearing the tires crunching through the brittle remains. He set his screens at maximum and switched his headlamps up to full brightness.

The vehicles that flanked him dropped back perhaps eighty feet, and he dimmed the screens that reflected the glare of their lights.

He released a flare, and as it hung there, burning, cold, white, and high, he saw a charred plain that swept on to the edges of his eyes' horizon.

He pushed down on the accelerator, and the cars behind him swung far out to the sides to avoid the clouds that he raised. His radio crackled, and he heard a faint voice but could not make out its words.

He blew his horn and rolled ahead even faster. The other vehicles kept pace.

He drove for an hour and a half before he saw the end of the ash and the beginning of clean sand up ahead.

Within five minutes he was moving across desert once more, and he checked his compass and bore slightly to the west. Cars one and three followed, speeding up to match his new pace, and he drove with one hand and ate a corned-beef sandwich.

When morning came, many hours later, he took a pill to keep himself alert and listened to the screaming of the wind. The sun rose up like molten silver to his right, and a third of the sky grew amber and was laced with fine lines like cobwebs. The desert was topaz beneath it, and the brown curtain of dust that hung continuously at his back, pierced only by the eight shafts of the other cars' lights, took on a pinkish tone as the sun grew a bright red corona and the shadows fled into the west. He dimmed his lights as he passed an orange cactus shaped like a toadstool and perhaps fifty feet in diameter.
