One Door From Heaven

they run alone or in pairs, or in families, toward their vehicles, some glancing back in fear as more gunfire-Curtis hears it for sure this time-erupts, muffled but unmistakable, from the depths of the building.
        Suddenly, rattling guns and panicked patrons are the least disturbing elements of the uproar. Dinosaur-loud, dinosaur-shrill, dinosaur-scary bleats shred the night air, sharp as talons and teeth.
        With repeated blasts of its air horn to clear the way, a semi roars down the exit ramp from the interstate, straight toward the service area. The driver is flashing his headlights, too, signaling that he's got a runaway eighteen-wheeler under his butt.
        Some of the station's huge storage tanks hold diesel fuel, which is combustible but not highly explosive, although other tanks contain gasoline, which is without doubt a valid ticket to an apocalypse. If the hurtling truck slams into the pumps and sheers them off as though they were fence pickets, the explosions should convince locals in a ten-mile radius that Almighty God, in His more easily disappointed Old Testament persona, has finally seen too much of human sin and is angrily stomping out His creations with giant fiery boots.
        Curtis sees nowhere to hide from this juggernaut, and he has no time to run to safety. He's not at serious risk of being flattened by the speeding truck, because it would have to plow through too many service-station pumps and barricades of parked vehicles to reach him. Billowing balls of fire, arcing jets of burning gasoline, airborne flaming debris, and a bullet-fast barrage of shrapnel are more likely to be what the coroner will certify as the cause of his death.
        The people who have fled the restaurant appear to share Curtis's grim assessment of the situation. All but a few of them freeze at the sight of the runaway semi, riveted by the impending disaster.
        Engine screaming, klaxons shrieking, lights flashing as though with the fury of dragon eyes, the Peterbilt roars through an empty service bay, between islands of pumps. Station attendants, truckers, and on-foot motorists scatter before it. For them, certain death is instantly transformed into a terrific story to tell the grandkids someday, because the big truck doesn't clip even one pump, doesn't barrel into any of the vehicles hooked to the hoses and guzzling from the nozzles, but flies out from under the long service-bay canopy and angles toward the buildings, downshifting with a hack and grind of protesting gear teeth.
        The plosive squeal of air brakes, recklessly applied so late, reveals the driver not as a man at the mercy of an out-of-control machine, after all, but as a drunk or a lunatic. The tires suddenly churn up clouds of pale blue smoke and appear to stutter on the pavement.
        The Peterbilt sways, seems certain to jackknife and roll. Bursts of noise erupt from the brakes, and a series of hard yelps issues from the abused tires, as the driver judiciously pumps the pedal instead of standing on it.
        An alligator of tread strips away from one wheel and lashes across the pavement, snapping like a whipping tail.. The dog whimpers.
        So does Curtis.
        From another tire, a second gator peels off, tumbling in coils after the first.
        A tire blows, the trailer bounces, the stacks bark as loud as a mortar lobbing hundred-millimeter rounds toward enemy positions, another tire blows. An air line ruptures and pressure falls and the brakes automatically lock, so the truck skates like a pig on ice, with a lot more squeal than grace, though the biggest prize hog ever judged couldn't have weighed a fraction of the tonnage at which this behemoth tips the scales. In a reek of scorched rubber, with one last attenuated grunt of protesting gears, it shudders to a halt in front of the motel, next to the restaurant, still upright, hissing and rumbling, smoking and steaming.
        With a whimper, the dog squats and pees.
        Curtis successfully resists the urge to water the pavement, too, but he counts himself fortunate to have used the restroom only a short while ago.
        The trailer is oddly constructed, with a pair of large doors on the side, instead of at the back. An instant after the semi comes to a full stop, these doors slide open, and men in riot gear jump out of the rig, not staggering and bewildered, as they ought to be, but instantly balanced and oriented, as though they have
