Lightning

designed for eight-year-olds.
    When Chris saw squirrels frolicking farther back in the yard, near the woods, he wanted to feed them. Laura gave him a pecan roll and said, "Tear it into little pieces and toss the pieces to them. They won't let you get too near. And you stay close to me, you hear?"
    "Sure, Mom."
    "Don't you go all the way to the woods. Only about halfway."
    He ran thirty feet from the blanket, only a little more than halfway to the trees, then dropped to his knees. He tore pieces from the cinnamon roll and threw them to the squirrels, making those quick and cautious creatures edge a bit closer for each successive scrap.
    "He's a good kid," Thelma said.
    "The best." Laura moved the Uzi to her side.
    "He's only ten or twelve yards away," Thelma said.
    "But he's closer to the woods than to me." Laura studied the shadows under the serried pines.
    Plucking a few potato chips from the bag, Thelma said, "Never been on a picnic with someone who brought a submachine gun. I sort of like it. Don't have to worry about bears."
    "It's hell on ants, too."
    Thelma stretched out on her side on the blanket, her head propped up on one bent arm, but Laura continued to sit with her legs crossed Indian-fashion. Orange butterflies, as bright as condensed sunshine, darted through the warm August air.
    "The kid seems to be coping," Thelma said.
    "More or less," Laura agreed. "There was a very bad time. He cried a lot, wasn't emotionally stable. But that passed. They're flexible at his age, quick to adapt, to accept. But as good as he seems… I'm afraid there's a darkness in him now that wasn't there before and that isn't going to go away."
    "No," Thelma said, "it won't go away. It's like a shadow on the heart. But he'll live, and he'll find happiness, and there'll be times when he's not aware of the shadow at all."
    While Thelma watched Chris luring the squirrels, Laura studied her friend's profile. "You still miss Ruth, don't you?"
    "Every day for twenty years. Don't you still miss your dad?"
    "Sure," Laura said. "But when I think of him, I don't believe what I feel is like what you feel. Because we
expect
our parents to die before us, and even when they die prematurely, we can accept it because we've always known it was going to happen sooner or later. But it's different when the one who dies is a wife, husband, child… or sister. We don't expect them to die on us, not early in life. So it's harder to cope. Especially, I suppose, if she's a twin sister."
    "When I get a piece of good news—career news, I mea —the first thing I always think of is how happy Ruthie would have been for me. What about you, Shane? You coping?"
    "I cry at night."
    "That's healthy now. Not so healthy a year from now."
    "I lie awake at night and listen to my heartbeat, and it's a lonely sound. Thank God for Chris. He gives me purpose. And you. I've got you and Chris, and we're sort of family, don't you think?"
    "Not just sort of. We
are
family. You and me—sisters." Laura smiled, reached out, and rumpled Thelma's tousled hair. "But," Thelma said, "being sisters doesn't mean you get to borrow my clothes."

    In the corridors and through the open doors of the institute's offices and labs, Stefan saw his colleagues at work, and none of them had any special interest in him. He took the elevator to the third floor where just outside his office he encountered Dr. Wladyslaw Januskaya, who was Dr. Vladimir Penlovski's longtime protege' and second in charge of the time-travel research which originally had been called Project Scythe but which for several months now had been known by the apt code name Lightning Road.
    Januskaya was forty, ten years younger than his mentor, but he looked older than the vital, energetic Penlovski. Short, overweight, balding, with a blotchy complexion, with two bright gold teeth in the front of his mouth, wearing thick glasses that made his eyes look like painted eggs, Januskaya should have been a comic figure. But his unholy faith in the state and his zeal in working for the totalitarian cause were sufficient to counteract his comic potential; indeed he was one of the more disturbing men involved with Lightning Road.
    "Stefan, dear Stefan," Januskaya said, "I've been meaning to tell you how grateful we are for your timely suggestion, last October, that the power supply to the gate should be provided by a secure generator. Your foresight has saved the project. If we were still drawing from the municipal power lines… why,
