Paris in 1922 was a city of ghosts. Not the kind that rattled chains and moaned in attics, but the quieter kind—the ones that walked the boulevards in tailored coats and smoked Gauloises, the ones that sat in cafés and ordered absinthe and stared into the middle distance with eyes that had seen too much. Thomas Blackwood was one of those ghosts, though he didn't know it yet.

He had returned from the Western Front six months ago, carrying a medical bag full of bandages and a head full of things he wished he could unsee. The war had ended in November, but in Thomas's body the war continued, a private armistice that held only because he hadn't yet found the courage to sign the real one.

His small clinic sat on the Rue de Seine, a narrow space above a bakery that smelled perpetually of yeast and burnt sugar. During the day, Thomas treated the patients who could afford his modest fees—artisans, shopkeepers, the occasional retired civil servant. At night, he sat at his desk with his grandfather's medical Compendium spread before him, reading by the light of a single oil lamp.

The Compendium was bound in dark leather, its pages yellowed with age and stained with the coffee cups of three generations of Blackwood physicians. It contained seventy-two formulas for treating injuries and illnesses that had no name in conventional medicine—wounds that refused to heal, fevers that burned without cause, minds that shattered under the weight of memories. The first half Thomas had mastered during his medical studies. The second half sat locked in a vault owned by the Earl of Rivers, a man who had been his grandfather's friend and then his greatest enemy.

The door opened and a woman entered, shaking rain from a charcoal-grey cloak. She was English, Thomas could tell from the accent, though a refined accent meant nothing in Paris anymore. Everyone had lost something in the war. Everyone was running from something.

"Dr. Blackwood?" she said, her voice careful, measured.

"That's what the sign says."

She removed her hat and Thomas saw a face that was beautiful in the way that broken things are beautiful—still whole, but changed, carrying the evidence of its fractures like scars on marble.

"My name is Helen Wentworth. I was referred to you by a friend at the British Embassy. She said you have a gift for treating wounds that don't appear on the body."

Thomas set down his pen. "That's a very generous way of describing a man who treats shell shock with herbal tea."

Helen sat down without being invited and placed a small leather case on the desk between them. "I don't want tea, Dr. Blackwood. I want to know if you can help me remember my sister."

Thomas felt something shift in his chest, a subtle realignment like a bone settling back into its socket. "Your sister?"

"She died in 1917. Or rather, I think she died. I have no body, no grave, no confirmation. Just a letter that arrived three weeks after the Battle of the Somme, written in a hand I recognized as hers but containing words she would never have written. And ever since then, I've been unable to sleep without seeing her face."

Thomas opened the leather case. Inside was a photograph—two young women standing in a garden, one smiling at the camera, the other looking away with an expression that might have been sadness or might have been something else entirely. The woman looking away was Helen.

"This is your sister?" Thomas asked.

"Margaret. She was a nurse at a field hospital near Verdun. She wrote to me regularly until the letter that I told you about. After that, nothing. The Red Cross said she was missing. The British Army said she was missing. My father said she was dead and begged me to stop looking."

Thomas looked at the photograph, then at Helen, then at the Compendium on his desk. His grandfather's words echoed in his mind, from a passage he had read only weeks after returning from the front: "The mind carries wounds that the body cannot see. These wounds require a different kind of medicine—one that does not heal the flesh but restores the soul."

"I can help you," Thomas said. "But I need to understand what happened to your sister. And I think the answer lies in the second half of my grandfather's Compendium."

Helen's eyes narrowed. "What does your grandfather's book have to do with my sister?"

"Because my grandfather died treating a noblewoman with the same symptoms your sister displayed—memory loss, emotional detachment, a kind of waking sleep. And he died because he discovered that the noblewoman's illness was not natural. It was induced. Deliberately caused by a treatment that was being administered at a private clinic owned by the Rivers family."

The silence that followed was so complete that Thomas could hear the rain on the roof and the distant sound of a jazz band practicing in a basement somewhere down the street.

"Rivers," Helen said slowly. "My family has dealings with the Rivers family. They're patrons of the medical establishment. They fund research. They're respected."

"Respectability is the easiest thing to buy in Paris," Thomas said. "Especially when you're selling it to people who have lost everything and will pay any price for hope."

Helen stood up and walked to the window, looking out at the rain-slicked street. "What do you need from me?"

"Your sister's letters. Every one she wrote before that final letter. And your permission to begin treatment."

Helen turned back to him, and in her eyes Thomas saw something that made his breath catch—not hope, exactly, but the memory of hope, the ghost of it, the thing that hope had been before the war.

"Then we begin tonight," she said.

Thomas opened the Compendium to the first page and began to read, his voice low and steady in the lamplight, while outside Paris continued its endless dance of forgetting and remembering, healing and harm, the terrible beauty of a world that had learned to survive by learning to live with ghosts.

And for the first time since he had come home from the war, Thomas Blackwood felt something that was not grief. It was purpose. It was small and fragile, like a candle in a cathedral, but it was there, and it was enough.
