One Door From Heaven

alien contact. She shivers with the thrill of it.
        Old Yeller jumps from the motor home to the ground, the sisters reconvene over the maps, and Curtis returns to the co-pilot's seat.
        His bond with little sister is at all times established, twenty-four hours a day, whether he is focused on it or not. Now he focuses.
        The cockpit of the Fleetwood, the trees beyond the windshield, and the nunless lake beyond the trees all fade from his awareness, and Curtis is both inside the motor home and afoot in the world with Old Yeller.
        She pees but not all at once. Padding among the motor homes and the travel trailers, she happily explores this new territory, and when she finds something particularly to her liking, she marks the spot with a quick squat and a brief stream.
        The warm afternoon is gradually cooling as the clouds pour out of the west, roll down the rocky peaks, and, trapped between the mountains, condense into ever darker shades of gray.
        The day smells of the sheltering pines, of the forest mast, of rain brewing.
        Death-still, the air is also heavy with expectancy, as if in an instant, the eerily deep calm might whip itself into a raging tumult.
        Everywhere, campers prepare for the storm. Extendable canvas awnings are cranked shut and locked down. Women fold lawn furniture and stow it in a motor home. A man leads two children back from the lakeshore, all in swimsuits and carrying beach toys. People gather up magazines, books, blankets, anything that shouldn't get wet.
        Old Yeller receives unsolicited coos and compliments, and she rewards every expression of delight with a grin and the brisk wagging of her tail, although she cannot be distracted from her explorations, which she finds ceaselessly intriguing. The world is an infinite sea of odors and every scent is a current that either brings fresh life to complex memories or teases with mystery and a promise of wondrous discoveries.
        Curiosity and the measured payout of a full bladder lead Old Yeller through a maze of recreational vehicles and trees and picnic benches to a motor home that looms like a juggernaut poised to crush battalions in a great war that is straining toward eruption at any moment. Even compared to the twins' impressive Fleetwood American Heritage, this behemoth is a daunting machine.
        Sister-become is drawn to this caravan fit for Zeus, not because of its tremendous size or because of its formidable appearance, but because the scents associated with it both fascinate and disturb her. She approaches warily, sniffs the tires, peers cautiously into the shadows beneath the vehicle, and at last arrives at the closed door, where she sniffs still more aggressively.
        Aboard the Fleetwood, physically far removed from Old Yeller, Curtis nonetheless is disquieted and overcome by a sense of danger. His first thought is that this juggernaut, like the Corvette behind the crossroads store, might be more than it appears to be, a machine not of this world.
        The dog had penetrated the illusion of the sports car and had perceived the alien conveyance beneath. Here, however, she sees only what anyone can see-which strikes her as plenty strange enough.
        At the motor-home door, one sharp smell suggests bitterness, while another is the essence of rot. Not the bitterness of quassia or quinine; the bitterness of a soul in despair. Not the stench of flesh decomposing, but of a spirit hideously corrupted in a body still alive. To the dog, everyone's body emits pheromones that reveal much about the true condition of the spirit within. And here, too, is a twist of an odor suggesting sourness; not the sourness of lemons or spoiled milk, but of fear so long endured and purely distilled that sister-become whimpers in sympathy with the heart that lives in such constant anxiety.
        She has not a dram of sympathy, however, for the vicious beast whose malodor underlies all other scents. Someone who lives in this vehicle is a sulfurous volcano of repressed rage, a steaming cesspool of hatred so dark and thick that even though the monster currently is not present, its singularly caustic spoor burns like toxic fumes in sister-become's sensitive nose. If Death truly stalks the world in living form, with or without hooded robe and scythe, its pheromones can be no more fearsome than these. The dog sneezes to clear her nostrils of the stinging effluvium, growls low in
