The night was stifling, heavy with the scent of pine and damp earth, when Margaret first heard the scratching. It came from the direction of the old greenhouse, a sound like dry claws on glass, persistent and unnerving. Her dog, a wiry terrier named Pip, had been restless all evening, pacing and whining, his ears flat against his skull. Margaret tried to soothe him, but he wouldn’t settle, his gaze fixed on the dark outline of the greenhouse that stood sentinel at the edge of the property.
She lived alone in the caretaker’s cottage, a rambling Victorian that had seen better days, its gingerbread trim peeling and its porch sagging. The greenhouse had been part of the estate for over a century, a grand structure of iron and glass, now abandoned and overgrown. Margaret had always felt a strange pull toward it, a mix of fascination and dread. She’d explore its dusty aisles sometimes, careful to avoid the broken panes and rusted supports, but she never stayed long after dusk.
That night, she decided to ignore the scratching. She turned off the lights and climbed into bed, her book forgotten on the nightstand. Pip, however, refused to settle. He sat at the bedroom door, growling low in his throat. Margaret sighed and called him, but he didn’t move. Then, the scratching stopped, replaced by a sound that made her blood run cold: the slow, deliberate scrape of something being dragged across the floor of the greenhouse.
Margaret sat up, her heart hammering. She strained to hear, but there was only silence, then the soft crunch of footsteps on gravel. Someone was walking toward the cottage. She slipped out of bed and peered through the window, but the moon was hidden behind clouds, and she could see nothing but shadows. The footsteps grew closer, then stopped at her front door. A soft knock, three times.
Pip let out a frantic bark and bolted down the hall. Margaret followed, her legs trembling. She reached the door just as the knocking came again, more insistent. She pressed her eye to the peephole, but it was dark outside. ‘Who’s there?’ she called, her voice barely a whisper.
There was no answer, only a faint hiss, like air escaping a tire. Margaret realized with a start that the lantern on her porch—the one that had been broken for months—was now glowing, a sickly yellow light that flickered and cast long, distorted shadows. She stumbled back, and the knocking ceased. The light died, plunging the porch into darkness.
She stood there, frozen, for what felt like an eternity. Then, Pip let out a high-pitched yelp from the back of the house. She ran to the kitchen, where Pip was scratching frantically at the back door. The door was unlocked, and it swung open, revealing the greenhouse glowing with the same sickly light, its glass panes lit from within.
Margaret felt a compulsion to go out, to see what was inside. Her feet moved of their own accord, carrying her across the damp lawn. The grass was cold and wet, soaking her slippers. The light from the greenhouse pulsed, a rhythmic beat like a heartbeat. She pushed open the creaking door and stepped inside.
The air was thick with the smell of rot and something metallic. The light came from a single lantern hanging from the central beam, its flame burning without wax. Beneath it stood a figure, draped in shadows, its form barely visible. It turned and looked at her, and Margaret saw that its face was a shifting mass of roots and leaves, with eyes like twin voids.
It spoke, its voice like the rustle of dead leaves: ‘You let the dog out.’ Margaret screamed, but no sound came out. The lantern flickered, and the flame guttered, plunging the greenhouse into darkness. She felt hands—cold, rough—close around her throat, and then the world faded.
She woke in her bed, Pip licking her face. The sun was streaming through the window, and the greenhouse stood quiet and empty, its glass reflecting the morning light. Margaret sat up, gasping, her hand going to her throat. There were red marks, like finger-shaped bruises, already forming.
She never spoke of it, not to anyone. And every night, she locked her doors, and she kept Pip close. But even now, she can hear the lantern’s last gasp, the dying flicker of a flame that should not have burned, and she knows that the thing in the greenhouse is waiting, patient, for the night she forgets to keep the dog in.
