Free Lightning by Dean Koontz

not. She edged backward until she came up against the wall beside her bed.
    He stood with his arms at his sides, motionless, hands fisted.
    The McIlroy Home was not air conditioned. The bedroom windows were open, but the place was tropically hot. Yet Laura had not been sweating until she turned and saw Sheener. Now her T-shirt was damp.
    Outside, children at play shouted and laughed. They were nearby, but they sounded far away.
    The hard, rhythmic rasp of Sheener’s breathing seemed to grow louder, gradually drowning out the voices of the children.
    For a long time neither of them moved or spoke. Then abruptly he turned and walked away.
    Weak-kneed, sweat-soaked, Laura moved to her bed and sat on the edge of it. The mushy mattress sagged, and the springs creaked.
    As her thudding heartbeat deaccelerated, she surveyed the gray-walled room and despaired of her circumstances. In the four corners were narrow, iron-framed beds with tattered chenille spreads and lumpy pillows. Each bed had a battered, Formica-topped nightstand, and on each was a metal reading lamp. The scarred dresser had eight drawers, two of which were hers. There were two closets, and she was allotted half of one. The ancient curtains were faded, stained; they hung limp and greasy from rust-spotted rods. The entire house was moldering and haunted; the air had a vaguely unpleasant odor; and Willy Sheener roamed the rooms and halls as if he were a malevolent spirit waiting for the full moon and the blood games attendant thereon.
     
That night after dinner the Ackerson twins closed the door to the room and encouraged Laura to join them on the threadbare maroon carpet where they could sit in a circle and share secrets.
    Their other roomie—a strange, quiet, frail blonde named Tammy—had no interest in joining them. Propped up by pillows, she sat in bed and read a book, nibbling her nails continuously, mouselike.
    Laura liked Thelma and Ruth Ackerson immediately. Having just turned twelve, they were only months younger than Laura and were wise for their age. They had been orphaned when they were nine and had lived at the shelter for almost three years. Finding adoptive parents for children their age was difficult, especially for twins who were determined not to be split up.
    Not pretty girls, they were astonishingly identical in their plainness: lusterless brown hair, myopic brown eyes, broad faces, blunt chins, wide mouths. Although lacking in good looks, they were abundantly intelligent, energetic, and good-natured.
    Ruth was wearing blue pajamas with dark green piping on the cuffs and collar, blue slippers; her hair was tied in a ponytail. Thelma wore raspberry-red pajamas and furry yellow slippers, each with two buttons painted to represent eyes, and her hair was unfettered.
    With darkfall the insufferable heat of the day had passed. They were less than ten miles from the Pacific, so the night breezes made comfortable sleep possible. Now, with the windows open, currents of mild air stirred the aged curtains and circulated through the room.
    “Summer’s a bore here,” Ruth told Laura as they sat in a circle on the floor. “We’re not allowed off the property, and it’s just not big enough. And in the summer all the do-gooders are busy with their own vacations, their own trips to the beach, so they forget about us.”
    “Christmas is great, though,” Thelma said.
    “All of November and December are great,” Ruth said.
    “Yeah,” Thelma said. “Holidays are fine because the do-gooders start feeling guilty about having so much when we poor, drab, homeless waifs have to wear newspaper coats, cardboard shoes, and eat last year’s gruel. So they send us baskets of goodies, take us on shopping sprees and to the movies, though never the good movies.”
    “Oh, I like some of them,” Ruth said.
    “The kind of movies where no one ever, ever gets blown up. And never any feelies. They’ll never take us to a movie in which some guy puts his hand on a
