Chapter 1

On my daughter's twelfth birthday, the man who had abandoned me before our wedding seventeen years earlier stood beside my husband and cut her cake.

Only a few hours before that, I hadn't known he was back in Chicago.

I'd been standing over an autopsy table, lifting a silver bracelet from beside the wrist bones of a woman who had once been my best friend.

The chain had turned black. Its little charms were still there, including a crooked star at the end.

I'd soldered that star on myself.

At our graduation dance seventeen years ago, Vivian had called it ugly and threatened to take it off. The next day, she wore it to class. She held up her wrist and told me that once I became a real doctor, she'd let me make her a better one.

I became a forensic pathologist.

She disappeared a month before graduation.

"Audrey?"

My assistant spoke from the other side of the table. I realized my hand had been hanging in the air for some time, the chain still caught in my forceps.

"Do you recognize it?" she asked.

I couldn't answer right away.

An incomplete female skeleton lay on the stainless steel table. The remains had been recovered that afternoon from an underground water tank at an abandoned hotel by the lake. The hotel had been closed for more than fifteen years, and a developer was preparing to tear it down.

Workers had broken through a wall added later. First they saw a shoe. Then they saw the bones of a human hand.

The police hadn't found any identification.

But I knew who she was.

Or at least I knew whose bracelet this was.

"Bag this separately," I heard myself say. "Don't put a possible name into the system yet."

My assistant glanced at me. "But if you know her—"

"We need dental records and a DNA sample from the family. A bracelet is a personal effect. It isn't a formal identification."

My voice sounded steady. Years on the job had taught me not to let my feelings get ahead of the evidence.

My fingers still shook when I took off my gloves.

After Vivian vanished, everyone said she'd left on her own. One suitcase was missing from her apartment, her bank account had been emptied, and even the deposit on the place we'd rented together was gone.

The police found no sign of a break-in. Someone at the bus terminal thought they'd seen a woman who looked like her. Her mother kept the same phone number for two years before finally disconnecting it.

I was the only one who never believed she'd run away.

The night before she disappeared, Vivian called me. I was trying on my wedding dress and missed it.

Her voicemail lasted seven seconds.

"Audrey, I found something out about Dario. Don't marry him. Wait until I get back."

The next day, Vivian was gone.

The day after that, my fiancé, Dario Bellandi, vanished too. All he left me was a note.

Don't look for me.

I looked for him for an entire year.

Eventually I met Graham. We married, had a daughter, and made a life in Chicago. I never told him the whole story. I only said that a fiancé had walked out on me when I was young.

I put the rest in a box in the basement with my old textbooks, photographs of my wedding dress, and Vivian's missing-person flyer.

I thought I'd never have to open it again.

"It's Sophie's birthday today, right?" my assistant said gently. "Finish the rest tomorrow. She won't want her mom to miss the candles."

The clock read 6:40.

My daughter's birthday dinner had started at six. I'd promised that even if a body arrived at five, I would be home before the cake was cut.

"Lock up the evidence first," I said. "If anyone asks to examine or move the remains, they contact me directly."

I sealed the bracelet in an evidence bag and signed across the seal myself. The wind off the lake stung my eyes as I left the medical examiner's office.

Graham called twice while I drove home. I let it ring. I didn't know how to tell him over the phone that my best friend had never left Chicago.

She'd been in an underground water tank less than forty minutes from our house.

The kitchen lights were on when I pulled into the driveway. Balloons filled the window, and Sophie had taped a silver number twelve she'd cut out herself to the glass.

I heard her laughing inside. For a moment, I could breathe again.

Then I opened the door and smelled vanilla cake and melted chocolate.

Sophie sat at the kitchen island with her back to me, a crooked paper crown on her head. Graham stood behind her, unnaturally pale.

Another man stood in front of the cake.

He wore a tailored black coat. A cake knife rested in his right hand, and an old white scar showed beneath his cuff. Seventeen years had broadened his shoulders and softened the sharpness of his younger face.

I recognized him at once.

Dario Bellandi.

He set the first slice on Sophie's plate and looked up at me.

"There you are."

He said it as casually as a husband welcoming his wife home.

Sophie waved. "Mom, this is Dario. He says you were friends in medical school. He brought pictures of you from back then."

Dario smiled and pressed the tip of the knife into the second slice.

"You're late, Audrey." His eyes dropped to the work badge I was still wearing. "I suppose being a forensic pathologist keeps you busy."
