The envelope arrived on a Tuesday, which was the first sign something was wrong. Nobody sent paper mail anymore—not in 2045, and certainly not to someone like Elena Voss.

She turned it over in her hands. No return address. No postage stamp. Just her name in elegant script that looked hand-written, impossible as that seemed. The paper felt thick, expensive, old.

Inside, a single photograph.

Elena's breath caught. The image showed her standing in front of the Chrysler Building, but that wasn't the strange part. The strange part was her clothes—a tailored suit from the 1930s, her hair in finger waves, a genuine smile on her face that she'd never worn in her entire thirty-two years of life.

She'd never been to New York. Never owned anything remotely vintage. And she certainly never smiled like that.

"Quantum Photography Lab" read the stamp on the back, followed by a date: April 15, 1937.

Her phone buzzed. Unknown number.

"Did you receive it?" A woman's voice, aged and careful.

"Who is this?"

"Someone who's been looking for you for a very long time, Miss Voss. Or should I say, Miss Catherine Wells?"

Elena's hands trembled. Catherine Wells was a name she'd invented for a novel she'd never finished writing—a character who time-traveled to solve murders in old Manhattan. A character no one knew about except her.

"That's impossible."

"Is it? Check your left shoulder blade."

Elena pulled down her shirt collar with shaking fingers, angling toward the mirror. There, just visible: a small birthmark she'd had since childhood, shaped like a art deco skyscraper.

"The photograph is real, Miss Voss. And you have three days to decide if you want to know why you're in it—and how to get back there before the murder happens."

The line went dead.

Elena stared at the photograph, at her own impossible face staring back through ninety years of history.

Her doorbell rang.
