woman with gray hair pulled primly back poked her head in. “Christine, they’re waiting.”
“Just a sec, Margaret,” said Christine Prusik, chief forensic anthropologist of the FBI’s Midwest Forensic Sciences Laboratory. Its jurisdictional responsibilities took in most of the central corridor from the Great Lakes to the borders of the Gulf Coast states, which were handled by New Orleans forensics teams.
Prusik tucked her short chestnut hair behind her ears, revealing two gold studs—the only piece of female hardware on the special agent—and continued to scan her field notes with practiced eyes. Of medium height and well proportioned from years of swimming the backstroke—she’d been a county champion when she was in her early teens—she was adept at rebuffing the advances of men who hadn’t correctly read what she tried to make eminently clear through her body language: Hands Off.
Her mammoth desk—a fortress of piles, with no surface free on which to jot even a note—was still insufficient a space to display all the materials she needed to ponder a case and its possible permutations. On the floor wreathing around her desk were open field notebooks, forensic-ruled photographs, and postmortem summaries underscored and starred with Magic Marker blues and pinks. Prusik’s dynamic intelligence at once focused in on the most diminutive detail and nuance of trace evidence and panned out to the wide screen, factoring in the significance of geographiclocation, crime scene patterns, and any similarities and differences with other potentially linked cases.
To Prusik, working a case meant all information had to be at hand, to be positioned or repositioned on the floor as she stood hunched over, scanning downward like some bird of prey on patrol, intently searching for a telltale sign, something—anything—odd or out of place or deliberately wrong.
Wind buffeted the building. Slanted streaks of rain raced across the large-paned windows of her sixteenth-floor office overlooking downtown Chicago. Prusik leaned back in her chair, holding a color slide up to the light. Hurriedly she skimmed the stack sent by overnight courier, looking for one in particular, the angle shot of the neck. She preferred holding actual slides to toggling through an array of digital images on a flat screen. To her, a photographic positive was crisper on close-ups than on the digital counterparts from the new Canons most field agents preferred.
She propped a brown, crepe-soled oxford shoe on the edge of her desk. Her free hand tugged a tuft of her hair, snagging loose a few strands in the process, as she mulled one particular close-up of a gaping purple wound—a vicious cut—that perversely mimicked the contours of an open mouth along the abdominal cavity. Just then an itchy panic took hold of her, and the photographic slide slipped from her fingers onto the floor.
Prusik fumbled open the desk drawer and grabbed the small pewter pillbox she kept there. Many years ago it had belonged to her grandmother, and Christine had wondered what pills her mother’s mother would have kept in it. Swallowing one Xanax tablet dry, she lofted the Bose headset over her ears and flipped the lever of the CD player on the credenza. She closed her eyes in the hunt for calm, waiting for the near-trance-inducing chords of Bach’s Partita for Keyboard no. 1 to return things to order. She tightened her right fist, squeezing her pinkie against her palm. Pills couldn’t erase the fact things were getting worse.
Within a few minutes, the combination effect had worked—the modern miracle of neurochemistry acting in consort with Bach’s genius. Her breathing had slowed; her heart rate no longer frightened her.
The office phone rang, destroying her peace and startling her forward in the chair. It was Margaret, her secretary, nudging her again. But she wasn’t ready yet. She refocused on the short stack of slides in front of her and hunted for any forensic
