any stupid policeman or security guard who might question him.
Even the contents of the paper bag he carried primly on his knees would be justifiable to any random police check: two pint tins of interior enamel paint, a selection of small paintbrushes, a few cards of hardware screws and cupboard hooks-all things a new DIY home owner would be justified in possessing-complete with a purchasing slip drawn on a downtown San Francisco decorating store.
In such company, the roll of duct tape and the box cutter would be totally unremarkable.
He had taken equal care with his past assaults. In the last, he had been the grimy mentally deficient street person, and in the one before that, the slovenly truck driver, and so on. The police didn't have a clue whom they were truly pursuing.
A pity, in a way, that he could not be admired for his artistry and his genius.
Riding the thunder of its hydrojet drives, the SuperCat cut northeastward across the bay, its twin bladelike bows slicing cleanly through the low swells. Beyond the ferry's windows, shore lights glittered on as the misty dusk settled. This was the eight o'clock run, the last of the day, and the ferry's commodious passenger bay with its multiple rows of seating was three-quarters empty.
The woman whom he had honored with his attention sat in the front row to port. Contentedly munching a crisp apple purchased from the ferry's snack bar, her attention was lost in the book resting on her crossed knee. She was beautiful, as were all his ladies-the rapist was, after all, a connoisseur. A tall brunette, she was slender but full-breasted, her long midnight black hair worn up in a neatly pinned chignon. She was somewhere in her thirties, with flawless, creamy skin, lightly tanned and glowing with health.
Her eyes were gray, and they had glinted with good humor as she had bantered with the snack bar attendant. She was a regular. Every Tuesday and Thursday she crossed on the ten o'clock morning run from Vallejo and returned on this, the last evening boat.
What she did in the city, he wasn't quite sure. But she was clearly a woman of fashion and means; her clothes were always of superb taste and quality. This night she wore a trim gray cord pantsuit that matched her eyes and stiletto-heeled black boots.
He might allow her to keep those boots after he destroyed the rest of her clothing; they would add something to the experience.
She always read her way across the bay with a book taken from the briefcase she inevitably carried. In his weeks of preattack surveillance he had made a point of positioning himself to see the book titles as a method of getting inside her head, of deepening his advantage.
But what he had seen had puzzled him: Anthony M. Thornborough's Airborne Weapons of the West, The Greenville Military Manual of Main Battle Tanks, and the like. Tonight's book was a crumbling yellow-paged volume in some Germanic tongue. From its illustrations it was concerned with cavalry warfare. Such topics were inexplicable for such a refined and totally feminine individual, and totally inappropriate. He would punish her for her interest in them.
The ferry slowed as it nosed up the Mare Island shipping channel, with the blazing city lights of Vallejo to starboard and the scattered work arcs of the old Mare Island Navy Yard to port. The great turbocharged diesels grumbled down into an idle as the catamaran came off plane. They were turning in toward the docking slips, the floodlights of the ferry terminal glaring in through the forward windscreen.
The BART rapist gathered himself. It was time for the final act.
He held back, just keeping his prey in sight as they descended the boarding ramps and passed by the big octagonal terminal building. He knew precisely where she was going. His rented minivan was already parked beside her dove gray Lincoln LS sedan out in the far parking lot of the terminal. Away from the lights of the terminal, he paused to hastily transfer the box cutter and duct tape to his jacket pockets, depositing his shopping bag in a trash can. He left the purchasing slip in the bag. Let the police chase this yuppie commuter; he would dissolve in a matter of a few more hours.
Perhaps he would become a Seventh-day Adventist missionary next.
His prey was crossing the broad asphalt expanse of the emptied parking lot now. The only thing that could delay her fate was the presence of some
