Elena lived in a saltbox house wedged between the tidal marsh and the sea. Her summers were a blur of brine and barnacles, but one scorching June afternoon, she fell asleep on the dunes and woke with her shoulders the color of raw ham. Sunburn meant house arrest for a week, and her mother, a marine biologist, had no patience for peeling skin.
The next evening, her parents and her younger brother went to the community center’s indoor pool for a charity gala. Elena, now fourteen, was left alone until dusk. Her mother kissed her forehead, careful to avoid the burned patches, and said, ‘The tide’s low. Keep the windows shut. You know how the marsh smells.’ Then she was gone, their car pulling out of the gravel drive with a crunch.
Elena locked the front door, then checked the back. The house stood on stilts, overlooking a channel of black water that coiled through the Spartina grass. Her father had once joked that the marsh was the land’s memory, holding everything ever dropped into it. Elena had never liked that joke. Now, as the sun dipped toward the horizon, the shadows of the grass grew long and skeletal.
She made a game of switching on every lamp, even the ones in the guest bathroom. The kitchen was her last stop. She poured a glass of tap water, and as she drank, she noticed the digital clock on the microwave: 6:47. Sunset was at 7:22. She had thirty-five minutes. The house creaked, settling, or maybe the wind. She turned to look out the window over the sink. The marsh was a flat, silver expanse, and the water was the color of slate. Something moved at the edge of the yard—a white shape, low to the ground. Her heart lurched. It was just a plastic bag, caught on a dead branch. But the bag was not there before.
She forced herself to breathe and walked into the living room, where the TV was on, volume low. She sat on the sofa, facing the foyer, the staircase to the second floor behind her. She could hear the grandfather clock ticking in the hall—her parents never wound it, but it still kept time, a stubborn heartbeat. She wrapped her arms around her knees and stared at the door. The sun would be behind the trees in twenty minutes.
A sound came from the kitchen: a soft, wet slap, like a fish hitting the counter. Elena froze. She listened. Nothing. She told herself it was the ice maker. But the ice maker was in the fridge door, and the sound was too heavy. She slid off the sofa and crept toward the kitchen, her bare feet cold on the tile. She peered around the corner. The kitchen was empty. The glass of water was still on the counter, but now it was slightly misted, as if it had been in a cold room. And on the floor, just below the window, was a small puddle of dark water, already soaking into the grout. From the window, she saw a ripple spread across the channel, even though there was no wind.
That was when the phone rang. Elena jumped. It was the landline, an old rotary in the hallway. She picked it up. ‘Hello?’ Static. Then a voice, low and distorted, like a man speaking through water: ‘The tide is coming in.’ Elena slammed the phone down. Her parents had cell phones. No one would call the landline. She checked the clock: 6:55. Still twenty-seven minutes.
She decided to wait in the garage, where the door could be locked and she could see the driveway. But as she turned, she saw her reflection in the dark TV screen. Behind her, in the foyer, stood a figure—a tall, thin shape, its skin glistening like wet sand. It had no face, only a smooth, grey expanse, and it was dripping steadily onto the floor. Elena’s breath caught. She turned, but there was nothing there. The foyer was empty, but a trail of wet footprints led from the front door to the foot of the stairs and then vanished.
Elena’s skin, already raw, prickled with goosebumps. She grabbed the umbrella stand, felt the cold metal of a flashlight, and clicked it on. The beam cut through the dimness, but the hallway was clear. She moved to the foyer, shining the light on the floor. The footprints had vanished, but now she saw that the front door’s peephole was covered by a dark, wet leaf, and the brass knob was slick, as if oiled. She wiped it with her sleeve, but her sleeve came away stained with a black, sticky substance that smelled of dead fish and sulfur.
She backed away, toward the stairs. She didn’t want to go up, but she knew that the second floor had a bathroom with a lock, and she could hide there until her parents came. She climbed the stairs, her legs shaking. The staircase was narrow and creaked with each step. At the top, she saw that the hallway was darker than it should be—the bulbs in the sconces had burned out, casting long shadows. She moved to her parents’ bedroom, which had a balcony overlooking the marsh. She locked the door behind her and leaned against it, panting.
The clock on the nightstand said 7:05. Sun was almost gone. She went to the balcony doors and looked out. The marsh was now a silhouette, and the channel was a black ribbon. In the distance, she saw a light, a bobbing lantern, moving through the reeds. That in itself was wrong—no one walked the marsh at night. She watched as the light grew closer, and she could make out a figure, waist-deep in the water, carrying a long pole. It stopped at the edge of their yard and raised the lantern. For a moment, the light illuminated a face—but it was not a human face. It was a fish, with eyes like milky marbles, and its mouth opened and closed, as if gasping.
Elena stumbled back, pulling the curtains. She felt a presence behind her. She turned. The figure from the TV was there, now in the room, dripping onto the carpet. It was taller than the room, its head brushing the ceiling, and it was reaching out with long, webbed fingers. Elena screamed, but no sound came out. She threw herself at the door, but the door was gone. In its place was a wall of black, viscous water, rippling with heat. She looked around—the room was dissolving, the walls bleeding into darkness, and the only thing solid was the figure, now inches from her face. Its mouth split into a grin, and from its throat came a sound like the tide pulling back, a whisper that said, ‘You are mine now.’
The doorbell rang at 7:30. Elena’s parents stood on the porch, calling her name. The house was dark, every light off. They found her in the living room, standing in front of the TV, her hands pressed against the glass, which was cold and wet with condensation. She was staring at a static-filled screen, and when they touched her, she fell to the floor, convulsing. They called an ambulance. At the hospital, the doctors said she had suffered a psychotic break, brought on by sunstroke and dehydration. But when they asked her what she saw, she would only whisper, ‘The tide is coming in,’ in a voice that was not hers.
They never sold the house. They boarded it up, but sometimes, on foggy nights, neighbors report seeing a light in the window, and a figure standing at the edge of the marsh, carrying a lantern. And Elena, now an adult, lives in a small apartment inland, but she never looks at water without a shiver. She knows that the memory of the tide is patient. It waits for the next dry evening, when the sun burns long, and the door is left unlocked.
