Beverly Hills. An eighty-degree day in the middle of an otherwise frigid Minnesota winter.
  Rain falling briefly from an apparently cloudless blue sky. Although a lightning strike 
of this magnitude and intensity was undoubtedly a rare occurrence, it probably had 
happened before, sometime, somewhere, probably more than once. Of course it had. Of 
course.
  In fact, if you picked up one of those popular books in which the authors compiled all 
kinds of world records, and if you turned to the chapter on weather, and if you looked 
for a subsection entitled "Lightning," you would most likely find an impressive list of 
other serial lightning strikes that would put this one to shame. Freaky weather. That's 
what it was. That's all it was. Nothing stranger than that, nothing worse.
  For the time being, at least, Carol managed to put aside all thoughts of demons and 
ghosts and malign poltergeists and other such claptrap.
  In the relative quiet that followed in the wake of the fast-diminishing thunder, she 
felt her strength returning. She pushed up from the floor, onto her knees. With the 
clinking sound of mildly disturbed wind chimes, pieces of glass fell from her gray skirt 
and green blouse; she wasn't cut or even scratched. She was a bit dazed, however, and for 
a moment the floor appeared to roll sickeningly from side to side, as if this were a 
stateroom aboard a ship.
  In the office next door, a woman began to cry hysterically. There were shouts of alarm, 
and someone began calling for Mr. O'Brian. No one had yet burst into the office to see 
what had happened, which meant that only a second or two had elapsed since the lightning 
had stopped, although it seemed to Carol as if a minute or two had passed.
  Over by the windows, someone groaned softly.
  'Paul?" she said.
  if there was an answer, it was drowned out by a sudden gust of wind that briefly 
stirred the papers and leaves again.
  She recalled the way that branch had whipped across O'Brian's head, and she shuddered. 
But Paul hadn't been touched. The tree had missed him. Hadn't it?
  "Paul !"
  With renewed fear, she got to her feet and moved quickly around the desk, stepping over 
splintered maple branches and an overturned wastebasket.

  THAT Wednesday afternoon, following a lunch of Campbell's vegetable soup and a grilled 
cheese sandwich, Grace Mitowski went into her study and curled up on the sofa to sleep 
for an hour or so. She never napped in the bedroom because that formalized it somehow, 
and though she had been taking naps three or four days a week for the past year, she 
still had not reconciled herself to the fact that she needed a midday rest. To her way of 
thinking, naps were for children and for old, used-up, burnt-out people. She wasn't in 
her childhood any more-neither the first nor the second, thank you-and although she was 
old, she certainly wasn't used up or burnt out. Being in bed in the middle of the day 
made her feel lazy, and she couldn't abide laziness in anyone, especially not in herself. 
Therefore, she took naps on the study sofa, with her back to the shuttered windows, 
lulled by the monotonous ticking of the mantel clock.
  At seventy, Grace was still as mentally agile and energetic as she had ever been. Her 
gray matter hadn't begun to deteriorate at all; it was only her treacherous body that 
caused her grief and frustration. She had a touch of arthritis in her hands, and when the 
humidity was high-as it was today-she also suffered from a dull but unrelenting ache of 
bursitis in her shoulders. Although she did all of the exercises that her doctor 
recommended, and although she walked two miles every morning, she found it increasingly 
difficult to maintain her muscle tone. From the time she was a young girl, throughout 
most of her life, she had been in love with books, and she had been able to read all 
morning, all afternoon, and most of the evening without eyestrain; nowadays, usually 
after only a couple of hours of reading, her eyes felt grainy and hot. She regarded each 
of her infirmities with extreme indignation, and she struggled against them, even though 
she knew this was a war she was destined to lose.
  That Wednesday afternoon she took a break from the battle, a brief period of R and R. 
Two minutes after she stretched out on the sofa, she was asleep.
  Grace did not dream often, and she was even less often plagued by bad dreams. But 
Wednesday afternoon, in the book-lined study, her sleep was continuously disturbed by 
nightmares. Several times she stirred, came half awake, and heard herself gasping in 
panic. Once, drifting up from some hideous and threatening vision, she heard her own 
voice crying out wordlessly in terror, and she realized she was thrashing on the couch, 
twisting and torturing her
  aching shoulders. She tried to come fully awake, but she could not; something in the 
dream, something dark and menacing, reached up with icy, clammy hands and pulled her down 
into deep sleep again, down and down, all the way down into a lightless place where an 
unnamable creature gibbered and muttered and chuckled in a mucous-wet voice.
  An hour later, when she finally woke up and managed to cast off the clutching dream, 
she was standing in the middle of the shadow-shrouded room, several steps away from the 
sofa, but she had no memory of getting to her feet. She was shaking, sheathed in sweat.
  -I've got to tell Carol Tracy.
  -Tell her what?
  -Warn her.
  -Warn her about what?
  -It's coming. Oh, God...
  -What's coming?
  -Just like in the dream.
  -What about the dream?
  Already her memory of the nightmare had begun to dissolve; only fragments of it 
remained with her, and each of those disassociated images was evaporating as if it were a 
splinter of dry ice. All she could remember was that Carol had been a part of it, and had 
been in awful danger. And somehow she knew that the dream had been more than just an 
ordinary dream....
  As the nightmare receded, Grace became uncomfortably aware of how gloomy the study was. 
Before taking her nap, she had switched off the lamps. The shutters were all closed, and 
only thin blades of light Were visible between the wooden slats. She had the irrational 
but unshakable feeling that something had followed her up from the dream, something 
vicious and evil that had undergone a magical 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,
