The ballroom at Grosvenor Square was a furnace of candlelight and ambition. Lady Mothwing moved through it like a ghost, her gown of ivory silk catching fire from a hundred gas jets. Upon her shoulders rested a shawl embroidered with real butterfly wings—swallowtails and morphos, pinned by a London artisan who charged three hundred guineas for the honor. They shimmered when she turned. They always shimmered.

"Your father tells me you are engaged," said Captain Edward Ashworth, appearing at her elbow as though conjured. He smelled of tobacco and rain, which was ridiculous because it had not rained in London for three weeks.

Lady Mothwing did not look at him. She kept her eyes on the dancing couples, on the sea of powdered wigs and jeweled fans. "My father tells me many things, Captain. Most of them are lies."

"Then why do you let him?"

She finally looked at him. His eyes were the color of the sea outside Dover—gray, uncertain, full of things he would never say. She had seen that look before, in the officers who returned from the colonies with empty pockets and full hearts. It was a dangerous look. It made women do foolish things.

"Because lies are easier than truths," she said. "And because I am not permitted to choose."

He reached out, almost touched her hand, then withdrew. "You should choose anyway."

The music swelled. A waltz. She knew what he was asking without his saying it. She knew that if she said yes, her father would disown her, her mother would weep until her eyes failed, and society would exile her to the sort of boarding house where the tea was watered and the landlady judged you silently. She knew that if she said no, she would marry Sir Reginald Croft, and her father's debts would vanish, and her life would proceed exactly as it had always proceeded: a series of rooms, one after another, each more gilded than the last.

"I am not what you think I am," she whispered.

"Then what are you?"

She thought of the butterfly on her shoulder, its wings trembling against the silk. "I am a creature that flies into fire. And I do not know how to stop."

He said nothing. The waltz ended. The next dance began—a polka, bright and stupid. He bowed and disappeared into the crowd. She stood alone in the center of the floor, surrounded by hundreds of people, and felt the butterfly wings on her shoulders grow heavier with each passing minute.

The engagement was announced at dinner. Her father raised his glass and spoke of "fortunate arrangements" and "mutual affection." Her mother smiled with the tight, practiced smile of a woman who had smiled the same smile for forty years and meant none of it. Sir Reginald Croft sat across from her, a man of forty with silver in his beard and money in his veins. He looked at her the way a man looks at a painting he intends to buy: with appreciation, with calculation, with the quiet certainty that ownership follows appreciation.

Lady Mothwing ate her soup in silence. It was a clear consommé, perfectly prepared, utterly tasteless. She thought of Captain Ashworth's eyes. She thought of the butterfly on her shoulder. She thought of the word that had been whispered in her ear since childhood: duty. Duty. Duty. It was a word that sounded like a lock clicking shut.

That evening, she walked the gardens of the family estate in Berkshire. It was autumn, and the leaves had turned to gold and rust. The garden had once been magnificent—three hundred rose beds, a formal parterre, a maze of yew hedges that her grandmother had designed. Now half the beds were weeds, the parterre was cracked, and the maze had been closed for repairs that never came. She walked through the overgrown paths, her boots sinking into mud, and felt something she had not felt in years: anger.

Not at her father. Not at Sir Reginald. At the garden itself. At the beauty that had been cultivated, displayed, and abandoned in the same breath. At the way her family had treated her the way they treated the garden: as something to be maintained for the benefit of visitors, then left to decay when the visitors were gone.

A butterfly landed on her wrist. White, fragile, impossibly alive. She watched it for a long time. Then it flew away, and she was alone again.

On the eve of her wedding, Lady Mothwing went to the library. She had not been there in months—the roof leaked, and her father had ordered the windows sealed to save on glass. She lit a candle and found her grandmother's journal on a shelf behind a row of leather-bound ledgers. The journal was small, bound in faded blue leather, with a clasp that had rusted shut. She broke it open.

The entries were written in a cramped, precise hand. Her grandmother had been a woman of few words and many observations. She wrote of the weather, of the price of wheat, of the servants' children. And she wrote, in the margins, of things she was not supposed to write: of loneliness, of regret, of the slow suffocation of a life lived for other people's approval.

The final entry was dated 1823, three weeks before her grandmother's twenty-fifth birthday.

"We are not women," it read. "We are butterflies pinned to a board—beautiful to look at, dead to the touch. I married for duty. I raised children for duty. I smiled for duty. And now, on the eve of my death, I wonder if I ever lived at all."

Lady Mothwing sat on the floor of the library and read the entry three times. Then she took a sheet of paper and a pen and wrote a letter to Captain Ashworth.

She wrote: I will not come for me. I am sorry. I am so sorry.

She sealed the letter, addressed it, and set it on the table beside her candle. Then she went to her room, took the laudanum from her mother's locked cabinet, and drank it in one swallow.

***

She was found in the morning. A white butterfly was pinned to her pillow beside her face, its wings spread wide, its body small and still. The family announced she had died of a weak heart. The coroner agreed. Captain Ashworth received the letter three weeks later, by which time he had already shipped out for the colonies.

Sir Reginald Croft married another woman three months later. The estate was sold to a developer who tore down the stables and built a row of terraced houses. In the garden, a single white butterfly landed on the overgrown rose bush and flew away.

The rose bush did not bloom that year.
