One Door From Heaven

for heroic purpose, is harder than his mother warned him that it could be and much harder than ever it appears to be in movies.
        Alerted by scent or by intuition, the woman in the open doorway turns her head so quickly, so sharply that a snap should be audible, and on sight she knows Curtis. Her eyes flare wide, as any startled woman's would, and she raises one hand defensively as though to ward off bullets, as any frightened woman might, but in the same instant, she is betrayed by her smile, which is as inappropriate here as would be a sudden burst of song: a predatory smile of serpent cracking wide to swallow mouse, of leopard poised to make a deadly pounce.
        In the telling moment, when you either have the right stuff or you don't, Curtis discovers he has it, and in abundance. He squeezes the trigger once, twice, rocked by the recoils, and he neither falls back in the face of the assassin's fierce shriek nor merely holds his ground, but takes a step forward and fires again, again, again.
        Any fear that this woman might be the legitimate twin of the one lying dead in the SUV is put to rest even as the first round from the pistol shreds through her torso. Although the human form serves well the wars of this world, it isn't the ideal physiology for a warrior species, and even before the first bullet leaves the barrel, the bad mom begins to morph into something that Curtis would rather not have seen this soon after consuming an entire large bag of cheese popcorn washed down with Orange Crush.
        In the first instant, the killer launches itself at him, but it is mortal, not supernatural, and though its rage would drive it into the teeth of death, its cunning overcomes blind fury. Even in the act of springing at Curtis, it kicks off the corner of the cashier's station and launches itself in a new trajectory, toward the tall shelves of packaged goods.
        Of the four additional shots that Curtis fires, three find their mark, jolting the shrieking assassin, which scrambles quickly up the shelves as an acrobat might swarm a ladder with leaps and flourishes. Hampered by a cascade of cans and bottles and boxes, the killer is in fact scaling an avalanche, yet it blitzes past all tumbling obstacles to reach the summit even as the fourth shot strikes and the fifth misses.
        During this lightning swift ascent, the killer morphs toward more than a single shape, simultaneously sampling a menagerie of murderous species, bristling with talons and beaks, with horns and spikes and scapulae. Hands grasp, pedipalpi quiver, spiracles ripple, pincers snap like scissors, and other ill-defined extrusions appear and at once vanish in a roiling tumult of glistening carapaces that melt into whipping tails, in snarls of coarse hair that smooth into scaly flanks, expressing a biological chaos that makes Curtis's confusion in the twins' bathroom seem, by comparison, merely an amusing faux pas. Clinging for but a fraction of a second to the crest of the shelves, hunched under the fluorescent lights, all shapes and none, and every shape a lie, the churning beast might be the Beast himself, recognizable to the poet Milton as the ruling prince of the "darkness visible" in Hell-and then it's gone into the next aisle.
        Although mortal, the assassin will not die as easily as Curtis would have perished if it had reached him. The spirit of every evil is resilient, and in this case, so is its flesh. Its wounds won't heal miraculously, but those it has might not be sufficient to put it down permanently.
        Curtis is loath to turn his back on this crippled but dangerous adversary; however, Cass and Polly are outside with the second killer and helpless against its savagery. With at most five rounds left in the pistol, he's committed to further distracting the remaining assassin in order to give the twins a chance to flee.
        Frantic, clambering across the treacherously shifting drift of merchandise that has crashed from shelves to floor, he makes his way to the open door, praying that his two beautiful benefactors, glass-shod Cinderellas, fragile flowers of Indiana, will not have their kindness to him repaid by bloody death.
        WHILE DIESEL FUEL FED the hungry belly of the Fleetwood, Earl Bockman droned on about the varieties of packaged macaroni dishes, frozen and not, that he and Maureen stocked in the store. He held forth not in the tone and manner of a merchant trying to drum up a few
