The Mask

metamorphosis from a creature of the imagination into one composed of solid flesh, something that was now crouched in a corner, watching, waiting.
    —Stop it!
    —But the dream was…
    —Only a dream.
    Along the edges of the shutters, the taut threads of light abruptly brightened, then dimmed, then grew bright again as lightning flashed outside. A roof-rattling crash of thunder quickly followed, and more lightning, too, an unbelievable amount of it, one blue-white explosion after another, so that for at least half a minute the cracks in the shutters looked like sputtering electrical wires, white-hot with sparking current.
    Still drugged with sleep and slightly confused, Grace stood in the middle of the unlighted room, rocking from side to side, listening to the thunder and the wind, watching the intense pulse of lightning. The extreme violence of the storm seemed unreal, and she concluded that she was still under the influence of the dream, misinterpreting what she was seeing. It couldn’t possibly be as savage outside as it appeared to be.
    “Grace…”
    She thought she heard something call to her from over by the tallest set of bookshelves, directly behind her. Judging from its slurred, distorted pronunciation of her name, its mouth was severely malformed.
    There’s nothing behind me! Nothing.
    Nevertheless, she did not turn around.
    When the lightning finally stopped and the long-sustained crescendo of thunder subsided, the air seemed thicker than it had been a minute ago. She had difficulty breathing. The room was darker, too.
    “Grace… ”
    A confining mantle of claustrophobia settled over her. The dimly visible walls appeared to ripple and move closer, as if the chamber might shrink around her until it was precisely the size and shape of a coffin.
    “Grace… ”
    She stumbled to the nearest window, banging her hip against the desk, nearly tripping over a lamp cord. She fumbled with the lever on the shutters, her fingers stiff and unresponsive. At last the slats opened wide; gray but welcome light poured into the study; forcing her to squint but gladdening her as well. She leaned against the shutters and stared out at the cloud-plated sky, resisting the insane urge to look over her shoulder to see if there really was something monstrous lurking there with a hungry grin on its face. She drew deep, gasping breaths, as if the daylight itself—rather than the air—sustained her.
    Grace’s house was atop a small knoll, at the end of a quiet street, sheltered by several large pine trees and by one enormous weeping willow; from her study window she could see the rain-swollen Susquehanna a couple of miles away. Harrisburg, the state capital, huddled solemnly, drearily along the river’s banks. The clouds hung low over the city, trailing bedraggled beards of mist that obscured the upper floors of the tallest buildings.
    When she’d blinked the last grains of sleep out of her eyes, when her nerves had stopped jangling, she turned around and surveyed the room. A quiver of relief swept through her, unknotting her muscles.
    She was alone.
    With the storm temporarily quiet, she could hear the mantel clock again. It was the only sound.
    Hell, yes, you’re alone, she told herself scornfully. What did you expect? A green goblin with three eyes and a mouthful of sharp teeth? You better watch yourself, Grace Louise Mitowski, or you’ll wind up in a rest home, sitting all day in a rocking chair, happily chatting with ghosts, while smiling nurses wipe drool off your chin.
    Having led an active life of the mind for so many years, she worried more about creeping senility than about anything else. She knew she was as sharp and alert as she had ever been. But what about tomorrow and the day after? Because of her medical training, and because she had kept up with her professional reading even after closing down her psychiatric practice, she was up to date on all the latest findings about senility, and she knew that only fifteen percent of all elderly people suffered from it. She also knew that more than half of those cases were treatable with proper nutrition and exercise. She knew her chances of becoming mentally incapacitated were small, only about one in eighteen. Nevertheless, although she was conscious of her excessive sensitivity regarding the subject, she still worried. Consequently, she was understandably disturbed by this uncharacteristic notion that something had been in the study with her a few moments ago, something hostile and…
