The fog in Edinburgh in October was not simply weather. It was a presence, a mood, a living thing that crept through the narrow closes and winding wynds of the Old Town and made everything feel like a dream you couldn't wake up from. Agnes Blair sat by the window of her townhouse on Queen Street and watched the fog press against the glass, yellow and thick as old parchment.

She had been ill for three weeks. Three weeks of doctors who could not explain the changes in her body. Three weeks of watching her reflection in the mirror and seeing something that was becoming less and less human with each passing day.

Her skin was becoming translucent. Not pale—translucent. Like fine porcelain held up to candlelight, you could see the faint blue tracery of veins beneath the surface. Her blood had grown thick and oily, and when she moved her hands, the joints made a soft clicking sound, like glass beads rolling against glass.

Mary was the one who understood. Mary, her sister, the one she had left in the anatomy cellar of Edinburgh University while she climbed into the salons of the city's elite. Mary, who had written the papers on cellular regeneration that Agnes had taken and published under her own name. Mary, who had been twenty-four years old when Agnes took everything and called it her own.

The door opened and Mary stepped into the drawing room. She was wearing a dark dress that had seen better days, and her hands were stained with ink and formaldehyde from the anatomy laboratory. She looked exactly as Agnes remembered: plain, serious, intelligent in the way that made other people uncomfortable.

"Agnes."

"Mary." Agnes did not rise from her chair. "You've come."

"I received your letter." Mary set her satchel on the table between them. "You said it was urgent."

"It is." Agnes held out her hand. The skin was almost completely translucent now. Beneath it, the veins glowed faintly blue in the gaslight. "Look."

Mary took her sister's hand and examined it with the detached curiosity of a scientist observing a specimen. "The cellular synthesizer," she said. "The one based on my research."

"Based on your research, published under my name, celebrated at the Royal Society of Edinburgh." Agnes withdrew her hand. "It's failing. Generation twelve is producing proteins we didn't predict. My cells are turning against me."

Mary was silent for a long moment. Then she opened her satchel and withdrew a small glass vial. The liquid inside was colourless, almost invisible.

"This is the reverse enzyme. It will stop the cellular degradation."

Agnes's breath caught. "You have a cure."

"I have a correction." Mary set the vial on the table. "The synthesizer was designed with a flaw. I built it into the foundation. The only thing that can stop the degradation is human chorionic gonadotropin—the hormone produced during pregnancy. Your body has not produced this hormone because you have never been pregnant. Because you chose your career. Because you chose society. Because you chose everything except the one thing that could save you."

Agnes stared at the vial. It sat on the polished mahogany table between them, catching the gaslight like a diamond.

"You're asking me to—"

"I'm telling you the truth." Mary's voice was calm. Scientific. "You took my research, Agnes. You published it under your name. You married Henry Dawson and became Lady Blair. You entered the salons and the drawing rooms and the circles where women like me were not welcome. You built a life of perfect, immaculate beauty. And in doing so, you built a cage from which there is no escape."

Agnes stood up. She walked to the mirror on the far wall and looked at her reflection. The woman staring back at her was beautiful in a way that was almost supernatural. Her skin was translucent, luminous, glowing faintly in the gaslight. Her features were sharp and precise, like a sculpture carved from ice. She looked like a specimen preserved in formaldehyde—perfect, eternal, alive in the way that a preserved thing is alive.

"I don't want to be saved," she said.

Mary was silent.

"I don't want to be pregnant. I don't want to be imperfect. I don't want to be human." Agnes turned from the mirror and looked at her sister. "I want to be beautiful. And this—" she held up her translucent hand, "—this is beautiful, Mary. Don't you see? I'm becoming something more than human. Something perfect. Something eternal."

Mary looked at the vial. Then she looked at her sister. Her expression was unreadable.

"You're making a mistake," she said.

"Perhaps." Agnes sat back down in her chair. "But it's my mistake. And I'll make it."

She picked up the vial and held it in her hand. The liquid inside caught the gaslight and scattered it into tiny rainbows across the walls of the drawing room.

"Keep it," she said. "You'll need it. There will be other patients. Other women who want to be perfect. And I will be here, in my townhouse on Queen Street, watching the fog roll in and waiting for the day when I become something more than a woman."

Mary took the vial and put it in her satchel. She stood up and walked to the door. She paused with her hand on the knob and looked back at her sister.

"The frogs, Agnes," she said. "Remember the pond? The one behind our mother's house? You dropped them into the boiling water and watched them die. I thought you were cruel. Now I understand that you were just doing science. Observing. Recording. Not judging."

She opened the door and stepped out into the fog.

Agnes sat alone in the drawing room. She picked up the vial from the table and held it up to the gaslight. The liquid inside was colourless, almost invisible. She smiled.

Outside, the fog pressed against the windowpane, thick and yellow, swallowing the city whole.

Three weeks later, Agnes Blair died. But she did not decompose. Her body was preserved by the very cells that had been destroying her, locked in a state of perfect, eternal stasis. She became the most remarkable specimen in the history of the Royal Society of Edinburgh—a woman who had chosen beauty over life, perfection over truth, and in doing so, had become something more than human.

Mary kept the vial on her desk in the anatomy cellar. She never used it. She didn't need to. The disease had done its work. The correction was unnecessary. Agnes had made her choice, and the choice had made her.
