The garage was deserted. Her car was twenty feet from the elevator. She looked around carefully, then ran to the car, slid inside and locked the doors, her heart pounding. She headed downtown, under a sky the color of malice, dark and foreboding. The weather report had said rain. But it's not going to rain, Ashley thought. The sun is going to come out. I'll make a deal with you, God. If it doesn't rain, it means that everything is all right, that I've been imagining things.

Ten minutes later, Ashley Patterson was driving through downtown Cupertino. She was still awed by the miracle of what this once sleepy little corner of Santa Clara Valley had become. Located fifty miles south of San Francisco, it was where the computer revolution had started, and it had been appropriately nicknamed Silicon Valley.

Ashley was employed at Global Computer Graphics Corporation, a successful, fast-growing young company with two hundred employees.

As Ashley turned the car onto Silverado Street, she had the uneasy feeling that he was behind her, following her. But who? And why? She looked into her rearview mirror. Everything seemed normal. Every instinct told her otherwise. Ahead of Ashley was the sprawling, modem-looking building that housed Global Computer Graphics. She turned into the parking lot, showed the guard her identification and pulled into her parking space. She felt safe here. As she got out of the car, it began to rain.

At nine o'clock in the morning, Global Computer Graphics was already humming with activity. There were eighty modular cubicles, occupied by computer whizzes, all young, busily building Web sites, creating logos for new companies, doing artwork for record and book publishing companies and composing illustrations for magazines. The work floor was divided into several divisions: administration, sales, marketing and technical support. The atmosphere was casual. The employees walked around in jeans, tank tops and sweaters.
