Even as some of Sam's devices connected him to the world, others protected him from its harshness. Alarm systems in his car and condo kept criminals at bay, while climate control kept the air comfortable and compact discs soothed away distracting noise. A monstrous multi-armed black machine he kept in his spare bedroom simulated the motions of running, cross-country skiing, stair climbing, and swimming, while monitoring his blood pressure and heart rate and making simulated ocean sounds that stimulated alpha waves in the brain. And all this without the risk of the shin splints, broken legs, drowning, or confusion that he might have experienced by actually going somewhere and doing something. Air bags and belts protected him when he was in the car and condoms when he was in women. (And there were women, for the same protean guile that served him as a salesman served him also as a seducer.) When the women left, protesting that he was charming but something was missing, there was a number that he could call where someone would be nice to him for $4.95 a minute. Sometimes, while he was getting his hair cut, sitting in the chair with his protections and personalities down, the hairdresser would run her hands down his neck, and that small human contact sent a lonesome shudder rumbling through him like a heartbreak.

"I'm here to see Mr. Cable," he said to the secretary, an attractive woman in her forties. "Sam Hunter, Aaron Assurance Associates. I have an appointment."

"Jim's expecting you," she said. Sam liked that she used her boss's first name; it confirmed the personality profile he had projected. Sam's machines had told him that James Cable was one of the two main partners who owned Motion Marine, Inc., an enormously successful company that manufactured helmets and equipment for industrial deep-sea diving. Cable had been an underwater welder on the rigs off Santa Barbara before he and his partner, an engineer named Frank Cochran, had invented a new fiberglass scuba helmet that allowed divers to stay in radio contact while regulating the high-pressure miasma of gases that they breathed.
