The patient arrived at Blackwood Asylum on a Tuesday in October, 1893. She had no name, no history, no possessions except a small cloth bundle that contained a single photograph of a woman who was not her and a piece of paper with a single word written on it in handwriting that Dr. Edmund Blackwood could not identify.

The word was Augustin.

Edmund stood in the doorway of Ward Seven and looked at the woman sitting on the edge of her bed. She was Chinese, or at least she appeared to be, though her features were blurred by something—malnutrition, perhaps, or madness, or the slow erosion of identity that comes when a person has nothing left to hold onto. Her hair was cut short. Her hands were bare and cracked. Her eyes were fixed on the wall across from her bed, and she was repeating a word in a voice so quiet Edmund had to lean forward to hear it.

"Augustin. Augustin. Augustin."

He was forty-five, a psychiatrist of some repute in Edinburgh, and he had spent the last decade studying the fractured minds of soldiers who had returned from conflicts that had no names in any language he spoke. He had seen shell shock and combat fatigue and what the French called neurasthenia. He had seen men who could not stop shaking, women who could not stop screaming, boys who had been men and men who had been boys, all reduced to the same trembling animal state by the simple act of watching other human beings die.

But this woman was different. She was not a soldier. She was not European. She was not speaking in any language he recognized. And yet, when she looked at him, he felt something he had not felt in twenty years—a sensation so foreign that for a moment he could not name it.

Recognition.

He began her case file on that Tuesday. Patient Zero, he called her. Not because he believed she was the first of anything, but because she was the first patient whose condition defied every category he had been trained to use. She did not speak. She did not eat unless fed. She did not resist, but she did not comply. She simply existed, in the space between consciousness and something else.

That night, Edmund dreamed of snow.

He had never been to Russia. He had never seen snow outside Scotland, and Scotland snow was different from the snow in his dream—lighter, softer, less absolute. This snow was heavy and white and covered everything in a blanket so thick it seemed to silence the world. In the dream, he was standing in a field of snow and there was a woman in front of him, a Chinese woman with short hair and cracked hands, and she was looking at him with eyes that were not hers.

Her eyes were his eyes.

He woke up gasping. The clock on his desk said three in the morning. The asylum was silent except for the sound of wind against the windows and the distant sound of a patient crying in a room he could not locate.

He opened his journal and wrote: Patient Zero. Day 1. She does not speak. She repeats one word: Augustin. I do not know what it means. I will find out.

He did not find out. Instead, the dreams continued. Every night, the snow. Every night, the woman. Every night, the eyes that were his eyes looking back at him from a face that was not hers.

He began to notice things. Small things. The way the light fell through the asylum windows at exactly the same angle it had fallen through the windows of a building he had never visited but remembered clearly. The way the smell of the asylum's disinfectant was identical to the smell of a hospital he had worked in during a war he had not fought. The way Patient Zero's cracked hands were identical to hands he had held in the snow, hands that had been cold and trembling and alive.

He stopped sleeping. He drank less whiskey. He worked longer hours. He began spending every evening in Ward Seven, sitting beside Patient Zero and watching her watch the wall.

"Who are you?" he asked her one evening.

She turned her head slowly and looked at him. Her eyes were dark and empty and full. "I am the one who waits," she said in English, with an accent he could not place. "I am the one who remembers. I am the one who is waiting for Augustin."

"Where is he?"

She smiled. It was not a happy smile. It was the smile of a person who has waited so long that the waiting has become the only thing they have left. "He is everywhere. He is in the snow. He is in the war. He is in the mirror."

"The mirror?"

She pointed at the wall behind him. Edmund turned. There was no mirror on the wall. There was only plaster and paint and the faint crack that ran from ceiling to floor like a scar.

But when he looked at the crack, he saw his own reflection. And in the reflection, he was not forty-five. He was younger. He was wearing a uniform. He was standing in the snow. And he was looking at a Chinese woman with cracked hands and dark-tea eyes who was saying something he could not hear.

He turned around. Patient Zero was looking at him with an expression he could not read. Pity? Amusement? Recognition?

"You see it too," she said.

"See what?"

"The mirror in the wall."

He looked back at the wall. The crack was still there. The reflection was gone. He was forty-five again. He was Edmund Blackwood. He was a psychiatrist in Edinburgh. He was not a soldier. He was not in the snow. He was not wearing a uniform.

But he was beginning to understand that these distinctions were not as clear as he had been taught to believe.

He began searching the asylum's archives. In the basement, in a room full of dust and forgotten records, he found a journal. It was bound in leather, the pages yellowed and brittle, the handwriting familiar in a way that made his hands shake.

It was his handwriting.

But it was not his journal. Or rather, it was his handwriting but not his memories. The journal described a life he had not lived: a German officer named Augustin Keller, born in Prussia, educated in Berlin, drafted into the Wehrmacht, sent to the Eastern Front, where he fought in battles he did not remember and saw things he could not unsee. Where he met a Chinese woman in the snow and loved her and lost her and spent ten years in a Siberian prisoner-of-war camp thinking only of her.

Edmund sat on the basement floor and read the journal by the light of a single lamp and felt his mind unravel like thread pulled from a sweater.

He was Augustin. He had to be. The handwriting was his. The memories were his. The snow was his. The woman was his.

But he was also Edmund. He had been Edmund since birth. He had an M.D. from the University of Edinburgh. He had published papers on combat trauma. He had a practice in Edinburgh that patients respected and a house in the Old Town that he loved and a life that was real and solid and undeniable.

Unless it wasn't.

He went back to Ward Seven and found Patient Zero sitting on her bed, staring at the wall, repeating the word that had become the only thing connecting two lives that should not have been connected.

"Augustin," she said. "Augustin. Augustin."

Edmund sat beside her. He looked at the crack in the wall. He looked at his hands—Edmund's hands, forty-five-year-old psychiatrist's hands, soft and uncalloused and clean.

And then he understood.

There had been no穿越. There had been no time travel. There had been no German officer named Augustin Keller who had fought in the Eastern Front and fallen in the snow and been captured and spent ten years in a Siberian camp.

There had only been Edmund Blackwood, a psychiatrist whose mind had fractured under the weight of the trauma he had absorbed from his patients, whose imagination had created a complete alternate life to explain the dreams he could not stop having, whose psychosis had constructed an entire identity—Augustin Keller, German officer, lover of a Chinese woman, victim of the war—to contain the feelings he could not express as Edmund.

The war had not touched him physically. It had touched him psychologically. He had absorbed the stories of a hundred soldiers, a hundred broken minds, a hundred lives destroyed by violence, and his own mind had created a vessel to carry the weight. He had become Augustin because Edmund could not survive what he had seen.

And the woman—Patient Zero—she was not a Chinese soldier or a prisoner or a survivor of the Holocaust. She was a manifestation. A projection. A piece of his own fractured psyche given form and name and the ability to repeat the word that was the key to everything: Augustin.

She was him. He was her. The mirror in the wall was not a mirror at all. It was a window into the part of his mind that had become a German officer in the snow, loving a woman who was himself, waiting for a man who was himself, for a self that had shattered and reassembled itself into two pieces that could not find each other.

He reached out and touched Patient Zero's hand. Her fingers were cold and cracked and real. Or were they? Was any of this real?

"I'm sorry," he said. "I'm so sorry."

She looked at him. Her eyes were dark and empty and full. "You don't need to apologize," she said. "You're here now. That's all that matters."

He was here now. In Ward Seven. In the Blackwood Asylum. In Edinburgh, 1893. Sitting beside a woman who was himself, holding a hand that was his, in a room with a crack in the wall that was a mirror that showed him the life he had never lived and the life he could not survive.

The next morning, the orderlies found Edmund Blackwood dead in his study. He was sitting at his desk, his head resting on his arms, a pen in his right hand. On the desk was a letter written in his handwriting but in a language he could not have known—Chinese characters,歪歪扭扭 and desperate, addressed to a woman named Qin Tiane at an address in Warsaw, 1945.

Warsaw in 1893 did not exist as the Warsaw of 1945 would exist. There was no Holocaust. There was no war. There was no Augustin Keller and no Chinese woman in the snow and no mirror in the wall.

There was only Edmund Blackwood, a man whose mind had created a world to escape the one he lived in, and who had died in that world, sitting at his desk, writing a letter to a woman who was himself, in a language he had never learned, to an address that did not yet exist, in a city that was not yet destroyed.

The letter read, in Chinese:

Qin Tiane:

If you are reading this, I have finally understood. I was never Edmund. I was always Augustin. The asylum was my prison, not the walls around it but the walls inside my head. The war was not fought with guns but with memories. The snow was not in Russia but in my mind, where I buried everything I could not bear to carry.

You are not a patient. You are not a projection. You are the part of me that remembers how to love. You are the crack in the wall that lets the light in. You are the word I repeat when I cannot speak: Augustin. Augustin. Augustin.

I am coming to you. Not in this life. In the next. In the one where I am not a psychiatrist and you are not a patient and the war has not happened and the snow has not fallen and the only thing between us is a bakery in Stalingrad and a man loading his rifle with hands that do not shake.

Wait for me.

Augustin

They buried Edmund Blackwood in the cemetery next to the asylum. The letter was filed in the asylum records under "Patient Zero—Related Materials." It was never translated. It was never read. It sat in a drawer for a hundred years, a Chinese letter from a Scottish psychiatrist to a woman who did not exist, addressed to a city that did not exist, in a year that did not exist.

The mirror in the wall remained. The crack remained. And if you stood in Ward Seven on a quiet evening, you might hear, faintly, beneath the sound of the wind and the distant crying of patients, a voice repeating a word in a language that does not belong to any country:

Augustin. Augustin. Augustin.
