such a pastime entails. Although the San Francisco murders would have been committed in any case, Amanda would not have been involved if an obsession with Scandinavian crime novels had not developed into a morbid interest in evil in general and premeditated murder in particular. Though her grandfather was no advocate of censorship, it worried him that Amanda was reading books like this at fourteen. His granddaughter put him in his place by reminding him that he was reading them too, so all Blake Jackson could do was give her a stern warning about their content—which of course made her all the more curious. The fact that Amanda’s father was deputy chief of the homicide detail in San Francisco’s Personal Crimes Division fueled her obsession; through him she discovered how much evil there was in this idyllic city, which could seem immune to it. But if heinous crimes happened in enlightened countries like Sweden and Norway, there was no point in expecting things to be different in San Francisco—a city founded by rapacious prospectors, polygamous preachers, and women of easy virtue, all lured by the gold rush of the mid-nineteenth century.
Amanda went to an all-girls boarding school—one of a handful that still remained since America had opted for the muddle of mixed education—at which she had somehow survived for four years by managing to be invisible to her classmates, although not to the teachers and the few nuns who still worked there. She had an excellent grade-point average, although the sainted sisters never saw her open a textbook and knew she spent most nights staring at her computer, engrossed in mysterious games, or reading unsavory books. They never dared to ask what she was reading so avidly, suspecting that she read the very books they enjoyed in secret. Only the girl’s questionable reading habits could explain her morbid fascination for guns, drugs, poison, autopsies, methods of torture, and means of disposing of dead bodies.
Amanda closed her eyes and took a deep breath of fresh winter-morning air. The smell of pine needles told her that they were driving through the park; the stench of dung, that they were passing the riding stables. Thus she could calculate that it was exactly 8:23 a.m. She had given up wearing a watch two years earlier so she could train herself to tell time instinctively, the same way she calculated temperature and distance; she’d also refined her sense of taste so that she could distinguish suspect ingredients in her food. She cataloged people by scent: her grandfather, Blake, smelled of gentleness—a mixture of wool sweaters and chamomile; Bob, her father, of strength—metal, tobacco, and aftershave; Bradley, her boyfriend, of sensuality, sweat and chlorine; and Ryan smelled of reliability and confidence, a doggy aroma that was the most wonderful fragrance in the world. As for her mother Indiana, steeped in the essential oils of her treatment room, she smelled of magic.
After her grandfather’s spluttering ’95 Ford passed the stables, Amanda mentally counted off three minutes and eighteen seconds, then opened her eyes and saw the school gates. “We’re here,” said Jackson, as though this fact might have escaped her notice. Her grandfather, who kept fit playing squash, took Amanda’s heavy schoolbag and nimbly bounded up to the second floor while she trudged after him, violin in one hand, laptop in the other. The dorm room was deserted: since the new semester did not begin until tomorrow morning, the rest of the boarders would not be back from Christmas vacation until tonight. This was another of Amanda’s manias: wherever she went, she had to be the first to arrive so she could reconnoiter the terrain before potential enemies showed up. Amanda found it irritating to have to share the dorm room with others—their clothes strewn across the floor, their constant racket; the smells of shampoo, nail polish, and stale candy; the girls’ incessant chatter, their
