Maine man Stephen King does it again. Insomnia, his new chiller, debuts on the fiction list at a Kingly No. 1. Talk about perfect bedside reading: The novel tells the tale of an elderly man who can't get a decent night's sleep no matter how hard he tries. Guess this sort of thing is what happens when a horror writer grows older. Still, at a lengthy 787 pages-and with 1.5 million copies in print after four press runs-Insomnia is sure keeping plenty of readers up late. FICTION WEEKS ON LIST
