The bayou does not forget. It holds memory in its dark water like a miser holds gold—tight, close, and with the willingness to drown anyone who reaches for it.

Old Man Baptiste knew this better than most. At sixty-five, he had buried a wife and a son in the same yellow fever summer of 1872, and since then he had lived in a small cabin at the edge of Blackwater Bayou, far from the roads and the people and the memories that followed like mosquitoes in July.

His cabin was not much: four walls of hand-hewn cypress, a floor of packed earth, a chimney that smoked when the wind came from the east. But it was his, and it was far enough from the world that the world had largely forgotten him. This was the arrangement he had made with himself, and he kept it with the stubbornness of a man who had learned that waiting was the only power he had left.

The woman came on a night when the bayou was throwing lightning at the water like a man throwing stones at a window he wanted to break. Baptiste was sitting by his fire, mending a shirt that belonged to a man who would never wear it again, when he heard it: a sound between a howl and a sob, coming from the treeline.

He took his lantern and his wife's rifle and went to the door. The rain was coming down in sheets, and the lightning turned the bayou white for a fraction of a second at a time, revealing a world that looked less like Louisiana and more like the inside of a dream.

In one of those white flashes, he saw it: a woman wrapped in green mourning clothes, standing at the edge of the treeline. She was young—twenty-five, perhaps—with skin the colour of sea mist and hair dark as the deep ocean. And on her left cheek, barely visible beneath the lantern light, was a scar that looked like it had been drawn rather than inflicted.

She did not move. She did not speak. She simply stood there, watching him with eyes that were not human eyes. They were the colour of swamp water—dark, ancient, impenetrable.

Baptiste felt something shift in the architecture of his loneliness. He had spent twelve years alone, and he had learned that loneliness was not the absence of people but the absence of understanding. And this woman—this creature—understood him in a way that no human being ever had.

He opened the door. She walked in.

The cabin was small. The fire was small. But between them, in that small space, something vast was beginning to stir.

She sat by the fire. He sat across from her. And she spoke, in a voice that was the colour of expensive whiskey:

"Old man, I need to know something."

"Everything you need to know is already in you," Baptiste said. "You're just afraid to listen."

She smiled. It was not a comforting smile. "I've been told that before."

"By whom?"

"By the ones who sent me. By the ones who want me to destroy you."

He did not flinch. He had expected this. He had known this would happen. He had been waiting for it.

"Who are you?" he asked.

She looked at the fire. She looked at her hands—her human hands, which were beginning to tremble. And then she looked at him, and in her eyes he saw something that was almost tears.

"I was once human," she said. "I chose the bayou. I chose the darkness. I chose to become what I am now."

"And why are you here?"

"Because they sent me. Because they want me to destroy you. Because they think you're a threat."

"I am a threat," Baptiste said. "To what?"

"To the ones who want to control the bayou. To the ones who think the bayou belongs to them. To the ones who think they can tame what cannot be tamed."

She stood up. The green mourning clothes rustled like dry reeds. And then she changed. The human skin cracked like old paint. And beneath it was something else: fur, wet and glistening, the colour of pond scum and rotting leaves. A tail, thick and powerful, slapped against the floor. A face that was almost human but wasn't—a face like a wolf wearing a woman's mask.

Baptiste did not flinch. He had expected this. He had known this would happen. He had been waiting for it.

He raised his hand. Not in threat. Not in defense. In blessing.

"You were once human," he said. "I can see it in your eyes. In the way you hold yourself. In the sadness that lives beneath the fur. You were once human, and you chose this. You chose the bayou. You chose the darkness."

She made a sound that was not quite a scream. It was something between grief and rage.

"But you don't have to stay chosen," Baptiste continued. "You can come back. You can come back to the light. You can come back to the world."

She looked at him for a long time. Then she looked at the fire. Then she looked at her hands—her human hands, which were beginning to tremble.

"What do you want me to do?" she asked.

"Leave," Baptiste said. "Leave the bayou. Leave the marsh. Go somewhere where the roads go. Where the light reaches. Where you can be something other than what you were sent to be."

She nodded. Once. Slowly. Deliberately.

And then she was gone. Not in a flash of light. Not in a cloud of smoke. Simply gone. The way a good neighbour disappears after delivering a casserole: present, helpful, gone.

Baptiste sat down. He tended the fire. He listened to the rain.

He did not have to wait long.

The Uncle arrived at dawn, with six men and a rope and a look on his face that was equal parts triumph and terror. He had been waiting for this. He had been planning this. For twelve years he had waited for the old man to fall, and now here he was, standing in the ashes of a creature that had never existed in any church record, in a cabin that had never been blessed, with a man who had never taken any church oath.

"Witchcraft," the Uncle said. The word was simple. Final. Deadly.

Baptiste looked at him. He did not argue. He did not defend himself. He simply nodded, as if to say: yes, you win. Again.

They took him to the square in the nearby village. They tied him to the stake. They lit the fire. And as the flames rose around him, Baptiste looked up at the sky and smiled.

Because he knew something the Uncle did not: that the bayou would remember. That the creatures of the bayou would remember. That the fire that had burned the creature in his cabin would one day burn the Uncle too.

And it did.

Three years later, on a stormy night not unlike the one when Baptiste had first seen the creature, the Uncle died in his sleep. The doctor said it was his heart. Baptiste's successor—a young woman named Marguerite who had taken over the cabin—knew it was something else.

She knew it because on the night the Uncle died, she saw a figure standing at the edge of the treeline. Green mourning clothes. Scar on the left cheek. Eyes the colour of swamp water.

The figure did not speak. It simply watched the cabin for a long time. And then it turned and walked into the bayou, and was gone.

Marguerite never spoke of what she saw. She continued tending the herbs. She continued living. And on quiet evenings, when the tide went out and the beach was bare, she would walk down to the water's edge and look for the green figure in the mist.

She never found it again. But sometimes, on the stillest nights, she could hear the wind singing through the reeds of her ceiling, and she would close her eyes and remember.
