I found the first one in the scullery.

It was three days after Sir Sebastian returned from India, and the house was still settling into its old rhythms after the disruption of his absence. I had risen early, as was my custom, to inspect the kitchens before the cook came down. The gas lamps were still dim, casting long shadows across the flagstones, when I saw her—Martha, the kitchen maid—lying on her side by the copper tub.

At first I thought she had fallen asleep, sitting upright against the oven door. Then I saw that her eyes were open, staring at nothing, and her hands were folded over her chest as though in prayer.

I knelt beside her and pressed two fingers to her throat. Nothing. I drew back her eyelid. The pupil was fixed.

But it was the colour that troubled me most.

Her skin had taken on a peculiar purplish hue, the kind one might see in a bruise, except that it covered her entire face and neck with an evenness that no injury could produce. And when I turned her hand over, I noticed something else: the blood that had seeped from a small cut on her palm—the knife she had been using to slice bread before—had not run. It had coagulated into a dark, almost black mass, like tar.

I rose and went to the pantry for the physician's book. Dr. Gray had visited twice since my master's return, and I had noted his prescriptions. There was nothing in those pages for what I was witnessing. No fever, no plague, no known poison produced such effects.

I locked the scullery door and went upstairs.

The house contained five children—orphans Sir Sebastian had taken in during his travels. They slept in the east wing, separated from the main house by a corridor and a heavy oak door. I had instructed them, the evening before, to remain in their beds until morning. Now I climbed the stairs and tried each door in turn. All locked from within.

I called to them through the wood. No answer.

I took the key from my apron pocket and opened the eldest door first—Thomas, fourteen years old. He was sitting upright in his bed, his back to me, staring at the wall. His breathing was shallow and rapid.

"Thomas?"

He turned. His face was the colour of old parchment, and his eyes were wide with a terror that had already passed the point of screaming.

"Miss Eleanor," he whispered. "The smell. Can you not smell it?"

I could. It was faint, almost imperceptible beneath the lavender water and beeswax, but it was there—a sweet, cloying odour, like spices left to rot in the sun. It came from the east wing, from the room where Sir Sebastian had unpacked his trunks.

"Go back to bed, Thomas."

"I can't. My blood—it feels thick. Like water left to freeze."

I left him there and moved to the next room. Then the next. One by one, I checked each child. All were affected to varying degrees. The youngest, Lily—eight years old, with hair the colour of wheat—was the worst. She lay on her bed, trembling, her lips blue. When I pressed her hand, it was cold and stiff.

I went to Sir Sebastian's study and locked the door.

The trunks were still open, their contents spilling across the floor in a chaotic array of silk handkerchiefs, brass instruments, and small wooden boxes sealed with wax. I opened one of the boxes. Inside were packets of powder—saffron, cardamom, something finer and whiter than either. I lifted a packet to the light. The powder was crystalline, almost luminous.

On the desk lay Sir Sebastian's journal. I opened it to the last entry, dated three weeks before his departure from Calcutta:

"The natives speak of a sickness in the delta region, near the confluence of the Ganges and the Brahmaputra. They call it 'kalo rakt'—black blood. Those who contract it die within hours, and their blood turns to a substance like solidified tar. The local physician attributes it to contamination of the water supply. I have collected samples in sealed vessels for further study at home. If the East Company will fund the research—"

The entry ended mid-sentence.

I closed the journal and sat in the dark.

The house was silent now, save for the wind moving across the moor outside. I could hear it through the window panes—a low, mournful sound, like a voice calling from far away. The Yorkshire moors in November were a bleak place, and Blackwood Manor, perched on its edge, had always felt to me like a ship becalmed at the edge of the world.

I thought of my husband, Richard, who had died in the Crimea five years ago. He had written to me from the front, describing the cholera that had swept through the camp. "It takes them quickly, my dearest," he had written. "One moment they are standing beside me, and the next they are gone. There is no time for goodbyes."

I had kept every letter he ever wrote. They were in a drawer in my bedroom, wrapped in blue ribbon. I had not opened them since the funeral.

Now I rose and went to the bedroom. I opened the drawer and took out the bundle of letters. I did not read them. I simply held them, feeling the weight of them in my hands, the way one might hold the hand of a dying person.

When I returned to the study, I lit a candle and began to write.

I wrote the will first. It was a matter of routine, though the circumstances were not. I left Blackwood Manor to the Crown, with a provision that the children—if any survived—be placed in the care of the parish of Haworth. I left my personal effects to no one, for there was no one left to receive them.

Then I wrote the account.

I wrote everything I had seen: the discovery of Martha's body, the condition of the children, the contents of Sir Sebastian's trunks, the passage from his journal. I wrote it in clear, precise language, the way a competent housekeeper might record the inventory of a household. There was no room for hysteria in a document of this nature.

I sealed the will and the account in a single envelope and addressed it to the solicitor in Haworth. I would send it in the morning, if I could still move.

I carried the envelope downstairs and placed it on the hall table, where anyone entering the house would see it immediately.

Then I returned to the study and sat by the window.

The wind had grown stronger. I could hear it rattling the panes, and beyond that, the sound of the moor itself—a vast, empty expanse of heather and stone, stretching to the horizon in every direction. The stars were visible through a break in the clouds, cold and distant as ever.

I thought of Lily. She had been the smallest of the children, the one who clung to my skirt when she was frightened, who smiled with all her teeth when she was happy. I had promised her a doll when we returned from the village—the one I had seen in the shop window, with porcelain face and glass eyes. I had not bought it. I would not buy it now.

My fingers were beginning to feel stiff. I held my hand up to the candlelight and watched the pale skin, the blue veins beneath. They looked normal. They would not for long.

I thought of the powder in the wooden box—crystalline, luminous, brought from the other side of the world by a man who had never intended to harm anyone. He had collected it out of curiosity, out of the scientific spirit that had driven the age of exploration and empire. He had not known that curiosity could be a vector for death.

Neither had I.

The candle flickered. I trimmed the wick with my knife, though my hands were already beginning to tremble.

Outside, a fox was crying on the moor. Its voice rose and fell in a long, keening wail that sounded almost human. I had heard it many times before, but tonight it seemed to carry a meaning I had never noticed—the sound of something alone in the darkness, calling out to nothing.

I closed my eyes.

When I opened them, the candle had burned low. The wax had pooled around the base, forming a white lake in the brass holder. I picked up the knife and cut another section of wick.

My breathing was becoming difficult. Each inhalation required a conscious effort, as though the air itself had grown thick and resistant. I thought of Dr. Gray's prescriptions—laudanum, digitalis, quinine. None of them would help. None of them had ever been designed to help.

I thought of Richard again. Not the dying man, but the man he had been before the war—the man who had chased me through the garden of our engagement party, laughing, his face red with exertion and happiness. I had not thought of him in many years. Now he was here, vivid and present, and the pain of remembering him was almost a comfort.

The candle guttered. I did not trim the wick.

I sat in the chair by the window and waited.

The wind continued to move across the moor, carrying with it the scent of heather and cold earth and something else—something sweet and cloying, like spices left to rot in the sun. It came through the cracks in the window frame, seeping into the study, seeping into the house, seeping into my blood.

I closed my eyes one final time.

The last thing I heard was the fox, still crying on the moor, its voice rising and falling like a prayer, like a lament, like the sound of a world that would continue without us.
