Intensity

effectiveness of these weapons would depend on how fast the dogs came at her and whether she could aim well in the brief window of opportunity that they would give her.
        In a night as windless as it was deep, the seashell mobile hung motionless. Not even a single leaf stirred on the tree at the north end of the porch.
        The night seemed to be soundless. With her ears under the padded helmet, however, she wasn't able to hear small noises.
        She had the weird feeling that the entire world was but a highly detailed diorama sealed inside a glass paperweight.
        Without even the faintest breeze to carry her scent to the dogs, maybe they would not be aware that she had come outside.
         Yeah, and maybe pigs can fly but just don't want us to know.
        The fieldstone steps were at the south end of the porch. The motor home stood in the driveway, twenty feet from the bottom of the steps.
        Keeping her back to the wall of the house, she edged to her right. As she moved, she glanced repeatedly to her left at the railed north side of the porch, and out past the balustrade into the front yard directly ahead of her. No dogs.
        The night was so chilly that her breath formed a faint fog on the inside of her visor. Each flare of condensation faded quickly-but each seemed to fan out across the Plexiglas farther than the one before it. In spite of the ventilation from under her chin and through the six penny-size holes across the center of the pane, she began to worry that her own hot exhalations were gradually going to leave her effectively blind. She was breathing hard and fast, and she was hardly more able to slow her rate of respiration than quiet the rapid pounding of her heart.
        If she blew each breath out, angling it toward the open bottom of the face shield, she would be able to minimize the problem. This resulted in a faint, hollow whistling characterized by a vibrato that revealed the depth of her fear.
        Two small sliding steps, three, four: She eased sideways past the living-room window. She was uncomfortably aware of the light at her back. Silhouetted again.
        She should have turned all the lights out, but she hadn't wanted Ariel to be alone in the dark. In her current condition, perhaps the girl would not have known if the lights were on or off, but it had felt wrong to leave her in blackness.
        Having crossed half the distance from the door to the south end of the porch without incident, Chyna grew bolder. Instead of edging sideways, she turned directly toward the steps and shuffled forward as fast as the hampering gear would allow.
        As black as the night out of which it came, as silent as the high patchy clouds sailing slowly across fields of stars, the first Doberman sprinted toward her from the front of the motor home. It didn't bark or growl.
        She almost failed to see it in time. Because she forgot to exhale with calculation, a wave of condensation spread across the inside of the visor. At once, the pale film of moisture retreated like an ebbing surf, but the dog was already there , leaping toward the steps, ears flattened against its tapered skull, lips skinned back from its teeth.
        She squeezed the lever of the spray bottle that she clutched in her right hand. Ammonia shot six or seven feet in the still air.
        The dog wasn't within range when the first stream spattered onto the porch floor, but it was closing fast.
        She felt stupid, like a kid with a water pistol. This wasn't going to work. Wasn't going to work. But oh, Jesus, it had to work or she was dog chow.
        Immediately she pumped the lever again, and the dog was on the steps, where the stream fell short of it, and she wished that she had a sprayer with more pressure, one with at least a twenty-foot range, so she could stop the beast before it got near her, but she squeezed the trigger again even as the previous stream was still falling, and this one got the dog as it came up onto the porch. She was aiming for its eyes, but the ammonia splashed its muzzle, spattering its nose and its bared teeth.
        The effect was instantaneous. The Doberman lost its footing and tumbled toward Chyna, squealing, and would have crashed into her if she hadn't jumped aside.
        With caustic ammonia slathering its tongue and fumes filling its lungs, unable to draw a breath of clean air, the dog rolled onto its back, pawing frantically at its
