The hammer of rain on her umbrella obscured the sound of any footfalls behind her. Still, Catherine March cast an uneasy glance over her shoulder. Nothing seemed amiss. No darting shadows. No lurking silhouettes. But she knew she was being followed. The certainty tingled down her backbone as she hurried along the rain-slick sidewalk.

She gripped her umbrella and willed away the icy sensation. She was letting the gloomy day get to her. Grief clouded her common sense. Why would she be under surveillance? She lived a quiet and unassuming lifestyle. Most of her time was spent in a university lab or classroom. She consulted with various law enforcement agencies in and around Charleston, South Carolina, but a sleuthing, gun-toting forensic anthropologist was a figment of Hollywood’s imagination. Catherine didn’t investigate crimes or chase down criminals. Her job was to examine, analyze and inform. The cases on which she consulted were mostly cold, the skeletal remains of the victims picked clean by time, weather and predation.

Take her current assignment. She’d been tasked with creating biological profiles for fourteen separate sets of human remains recovered from an abandoned house on the outskirts of Charleston’s famed historical district. The former owner of the residence, a paraplegic named Delmar Gainey, had spent the last five years of his life in a nursing home and the previous two decades confined to a wheelchair. Before the accident that claimed his mobility, however, he’d murdered those fourteen women and sequestered their bodies in the walls of his home and in his backyard.

The remains of his victims might have stayed hidden forever if not for an ambitious house flipper, who had acquired the property at auction following Gainey’s death. The first gruesome discovery brought the police. The coroner had brought in Catherine.

Butterfly fractures in the long bones told the story of the women’s brutal captivity while striae patterns on the sternums and rib cages painted a vivid image of their deaths. The victims had been stabbed repeatedly with a serrated blade. All except one. Jane Doe Thirteen.

She was the anomaly. An outlier. An inconsistency that needled at Catherine even now as she thought about the single bullet hole in the back of the skull. In all likelihood, the entry wound had been made by a full metal jacket fired at close range from a 9 mm semiautomatic. An execution.

No bone trauma like the other victims. No nicks or fractures. Not even an exit wound.

Jane Doe Thirteen had definitely captured Catherine’s imagination, but for now she had more pressing business.

Clutching the plastic bag to her chest, she plunged on through the puddles.

What were the chances? she wondered as she cast another glance over her shoulder. What were the odds that not one but two old serial-killer cases with seemingly no relation to the other had entered her quiet, ordinary world to wreak havoc on her peace of mind? Delmar Gainey had died in his bed at the Cloverdale Rest Home, no doubt savoring his monstrous deeds to the bitter end. Orson Lee Finch—the so-called Twilight Killer—was still very much alive but destined to spend the rest of his days in the Kirkland Correctional Institution, housed in a specialized unit for the state’s most violent inmates.

Catherine had been little more than a baby when Gainey and Finch had stalked the streets of her city, each possessing a very different set of stressors, signatures and criteria. Then the remains had been found on Delmar Gainey’s property and, soon after, headlines had exploded with startling new developments in the Orson Lee Finch case.

Catherine had experienced little more than professional curiosity until her mother’s death unearthed a more personal revelation. Since early childhood, Catherine had known she was adopted. Her mother, Laura, had spoken openly about the circumstances of Catherine’s birth. You’ll have questions as you grow older. At some point, you may even feel your loyalties are divided. That’s only natural. But I want you to know that you can always come to me, Cath. There should be no secrets between us.

No secrets? Then why hadn’t Catherine known about the loose floorboard in her mother’s closet or the box of newspaper clippings stashed inside the secret compartment? Why hadn’t she been told about the photograph?

Why had Laura March, so pale and weak on her deathbed, pulled her daughter close and whispered a distressing message in her ear?

It’s all a lie.

A car horn sounded in the distance, drawing Catherine’s attention back to the present. She stood shivering on the curb as she waited for the light to change. It was a hot summer day, but the rain and her dark thoughts chilled her.

She took another quick check of her surroundings. She was alone on the street. No one else was about. No one that she could see. The rain had chased everyone inside. She was tempted to scurry across the intersection against the light, but she could almost hear her mother chastising her from the grave. Careful, Cath. Always look before you leap.

Grief settled heavily on her shoulders and tightened her chest. She couldn’t remember ever feeling more alone than she did at the moment, huddled beneath her umbrella and missing Laura March more than she would have ever dreamed possible.

Wiping a hand across her damp cheeks, she drew a sharp breath. The feeling was there again. That frigid whisper up her backbone. She turned, almost expecting to find her mother’s ghost floating toward her through the gloom. Instead, she saw a man watching her from a recessed doorway.

Their gazes collided before he glanced away, but in that fleeting moment of contact, Catherine experienced a flicker of recognition. She searched her mind for a time when their paths might have crossed. The man was memorable, not so much for his crudely tattooed arms but for the aura of danger that shrouded him. There was something sinister in his closely set eyes, something threatening in his body language. He looked to be middle-aged, his hair longish and slicked back, his cheekbones as sharp as razor blades. As if aware of Catherine’s scrutiny, he tipped back his head and blew a long stream of smoke out into the rain.

Her heart raced as she considered her options. Run away or confront him. Before she had time to think, she found herself walking toward him.

“Excuse me!” she called out. “Do I know you?”

Even as she continued to advance, she admonished herself for provoking a stranger on a deserted street, but she couldn’t seem to help herself. Grief did strange things to people. Maybe her emotions had been pent up for too long. Maybe her anguish had been suppressed to the point of explosion.

“Sir? Are you following me?”

He showed no visible reaction to the question, refused to acknowledge her presence with so much as a glance. He took another drag and then carefully flicked the cigarette butt into a puddle before he turned and walked away.

Catherine didn’t follow him. She watched until he was out of sight before she went back to wait for the light, positioning herself so that she could keep an eye on the sidewalk behind her. She tried to tell herself again that she was imagining things. The man had been minding his own business. If anything, she’d likely scared him away. What had she been thinking, harassing a total stranger?

No one was following her. Get over yourself. The only other person who knew of her discovery was her mother’s sister, and she couldn’t fathom a scenario where Louise Jennings would have her watched. Catherine still had a hard time believing her mother had kept secrets from her all these years, but the proof was in the plastic bag she hugged to her chest. The confirmation had been in her mother’s whispered confession.

It’s all a lie.
