The Nereid's Interval

Fantasy Mystery

Written in response to: "Write a story where the line between myth and reality begins to blur." as part of Ancient Futures with Erin Young.

Agata arrived on a Thursday, which her grandmother had always called the devil’s holiday, the day when the veil between visible and invisible grew thin as birch paper. She had not believed this as a child and did not believe it now, at thirty-four, carrying a sketchbook and a single rolling suitcase up the road from the bus stop to the house where no one lived anymore.

The village was smaller than she remembered. The well had been capped in concrete. The house green paint gone silver stood at the edge of a field where the rye had grown chest-high when she was eight and now grew to her knees, thinner, as if the soil had started forgetting what it was supposed to do.

She let herself in with the key the lawyer had sent. The rooms smelled of dried calendula and the particular silence of a place where someone has recently stopped breathing. On the kitchen table: a glass of water, a spoon, a cloth embroidered with red roosters. Her grandmother had been dead for three weeks. No one had come to clear the glass.

Agata set her violin on the table beside it and did not touch the water.

She had come to settle the estate, which it wasn’t. What she found was a field, a debt to the village council for unpaid levies, and a handwritten list of names her grandmother had left in an envelope marked for Agata only. The names were women’s names, twenty-two of them, with dates going back to 1887. No explanation. The paper had felt old, or felt old in the way certain documents absorb the weight of intention and become heavier than their pages. She had read the list three times before the bus reached the village limits and understood nothing except that she was being asked to carry something forward. She recognized no one on the list. She understood, dimly, that she was meant to. The lawyer had said, when she called to ask, that her grandmother had updated the envelope’s instructions every year for the last decade. The names remained the same, but she had kept adding to a separate sheet of paper that was not included, which had apparently been left at the lake.

The lake was a twenty-minute walk through the birch forest. She went that first evening because she could not sleep and because the house pressed against her in the way of houses that are waiting for something. She brought the violin without deciding to.

The lake was round and dark and had no official name on any map she had found, though her grandmother had called it the Mirror. The local name, she had heard as a child, was something older and unpronounceable, a word that meant approximately where they sing. In June the nereids were said to walk out of the water and sit in the birch trees, combing their hair with fish-bone combs and calling to travelers. Her grandmother had believed this. She had never gone to the lake alone after dark, and she had always left a crust of bread on the windowsill during Nereids’ week. Agata had assumed this was an old woman’s habit, the residue of a faith that had nowhere left to go.

She sat on the bank where a fallen tree had dried to silver and rosined her bow in the near-dark. She played the Chaconne by Bach, the D minor not because it was appropriate but because it was the only thing her hands knew how to do when she was grief-adjacent without being quite inside grief. She had played it at her mother’s funeral, then alone in her apartment the night her marriage ended. The Chaconne was not a sad piece, exactly. It was a piece about the fact of duration. About Johann Sebastian Bach, thirty-five years old, who came home from a journey to find his wife Maria Barbara dead and buried, and wrote, in the weeks that followed, forty-five minutes of music for a single unaccompanied instrument, the most concentrated statement of loss she knew how to make her body produce.

She played for a long time. The night was clear and the stars reflected in the lake’s surface until the two sky and water became indistinguishable, a single dark field in which she floated, small and unanchored, her sound the only thing marking her position in the world.

When she stopped, the water was moving. Its surface was still, but somewhere beneath it, in a slow circular motion, she could see the way you see a current in dark water: by the way the reflected trees tilted and recovered, tilted and recovered.

A fish, she thought. I am too tired to guess which one.

A woman surfaced. Not breaching but in the way a swimmer surfaces, when she has been underwater a long time and is in no hurry. Her hair was long and darkened by the water. Her face was the face of a woman somewhere between twenty and sixty, which is the face of both no one and everyone.

Agata did not run. She noted this about herself later: that her body’s first response was not fear but a kind of deep, confirming recognition, as if some part of her had been expecting this for years.

“You play well,” the woman said. Her accent reflected her grandmother’s.

“Thank you,” Agata said. This seemed, under the circumstances, insufficient. “Do you live here?”

The woman’s expression was something between amusement and patience. “We have always lived here.”

We. Agata looked at the water. The surface was still.

“I know what you are,” Agata said, because her grandmother had told her, though she had not believed it. The rusalki were the women who had died before their time by drowning, by grief, by the violence of men who were never held accountable. They rose in the warm months. If you heard them singing, you followed. This was not a choice.

“Do you,” the woman said. It was not a question.

“You’re a story,” Agata said. “You’re something people told because they needed an explanation.”

“And now?”

“Now I don’t know.”

The woman pulled herself onto the bank and sat a few meters away. She was wearing something white that could have been a shift or could have been simply the way the moonlight landed on her. Her feet were bare. She did not look cold. There was something in her stillness that was not human but not threatening and as absolute as the stillness of water.

“Your grandmother used to come here,” the woman said.

“I know.”

“She sang. She didn’t play ”

Agata had not known this. Her grandmother had never sung in front of her. She went silent, whenever Agata played, a silence It was a silence she had read as displeasure and now reconsidered.

“She left you a list,” the woman said.

“Yes.”

“Those are our names.”

The rye field behind Agata moved in a wind she could not feel. She thought about the dates on the list, the oldest going back a hundred and forty years. She thought about the glass of water on the kitchen table, the water no one had poured out. An offering. A kept promise.

“She remembered you,” Agata said.

“Yes. We asked her to. It is how we stay.” The woman looked at the water. “When no one says a name, what remains of it?”

Agata had no answer. She was a violinist, not a theologian. She had spent twenty years training her body to produce sounds from catgut and spruce and maple, and she could tell you everything about tension and resonance and the physics of a vibrating string, and none of that helped her now.

“What do you want from me?” she asked.

“Nothing you haven’t already brought,” the woman said, and nodded at the violin.

Agata understood. Or thought she did. She lifted the instrument again and played not the Chaconne this time but something older, a melody she had learned from a recording her grandmother sent one Christmas, a Belarusian folk tune whose name she had never looked up, had simply absorbed into her fingers and left there. Her grandmother had sent the recording in an unmarked cassette inside a birthday card, no note, the kind of message that makes sense only years later. She had never asked what it was. Now she thought perhaps she had always known, in the way that certain knowledge waits in the body before the mind has caught up. She had never played it for anyone. It had always felt too private, too much like something that belonged to a specific latitude and a specific century and a specific quality of winter light that she had only ever experienced secondhand, through stories.

She played it now, and the lake answered. Not in sound in motion. The water circled. The birches leaned without wind. And from the lake came, one by one, a presence she could not see but could feel the way you feel a room change when someone enters it a gathering, a crowd of women listening with the particular quality of attention that belongs to those who have waited a very long time.

She played until the melody ran out, then twice more, and each time it changed slightly the way traditional music does: something added, something dropped, the ornamentation shifting to accommodate the night.

When she finally lowered the bow, her hands were trembling.

“Will you come back?” the woman asked.

Agata thought about her apartment in Minsk, her students, the autumn concert season. She thought about the house with the calendula smell and the list of twenty-two names. She thought about how she had played the Chaconne at her mother’s funeral and cried only later, in the car, in the dark, where no one could see.

“Yes,” she said.

She walked back through the birch forest. The house was dark. She put the violin in its case and sat at the kitchen table with the list and a pen and began, one by one, to say the names aloud, quietly, the way you say something you want to remember. It took a long time. Some were difficult to pronounce; one, near the bottom, she recognized from a story her grandmother had told her once, about a girl who went to the lake in 1943 and did not come back, and how her mother had gone every evening to the bank and sung until she was too old to walk that far.

She said all twenty-two names. Then she drank the water from the glass on the table, which was cold and tasted of stone, of the specific mineral patience of underground water that has been waiting a long time to be of use.

Agata did not sleep. She sat until the window went gray and then lighter. When the birds started, she opened the violin case and played softly, facing the door, the way her grandmother must have sung, facing whatever direction the lake was in, north-northeast, through walls and birch trees and all the years.

The morning came in ordinarily. A dog barked somewhere in the village. A tractor started in a far field.

The light on the windowsill was the pale gray of early mornings that ask nothing of you yet.

The glass on the table was empty. She had drunk it without ceremony, the way you take medicine, not as performance but as fact, the small deliberate act of a woman who has decided to become someone’s witness. She did not know what the water would do to her, if anything. She did not believe in the cinematic kind of transformation, women becoming rivers or swans. She believed in the slower change: the way you become, over the years, whatever you have agreed to remember.

She was still there.
