The Thirteenth Window

The house on Wren Road had twelve windows.

Lisa counted them the day she moved in—front room, kitchen, hallway, two bedrooms, attic dormer, all neat and ordinary. Twelve. She liked knowing the number. It made the place feel contained, understandable.

But on the third night, she woke to a soft tapping.

Not on the walls. Not on the door.

On glass.

She sat up, heart thudding. The tapping came again—slow, deliberate, like someone testing the surface with a fingernail.

She checked the bedroom window.

Nothing.

She checked the hallway window.

Nothing.

She checked every window in the house, one by one, until she reached the attic stairs. The tapping was louder here, echoing down the narrow steps.

Lisa hesitated. The attic had only one window, the dormer facing the orchard. She climbed slowly, each step creaking under her weight.

At the top, she froze.

The attic had two windows.

One on the dormer.

And one on the far wall.

A window she had never seen before.

A window that shouldn’t exist.

It was tall and narrow, framed in dark wood that didn’t match the rest of the house. The glass was old, warped, and fogged from the inside. Something moved behind it—just a shadow, shifting slowly, like a person pacing in a small room.

The tapping came again.

Lisa stepped back. Her breath fogged in the cold attic air.

The shadow paused.

Then pressed closer.

A pale shape emerged behind the glass—long fingers, too many joints, tapping lightly, rhythmically. The silhouette of a head leaned forward, but the proportions were wrong. Too tall. Too thin. Too stretched.

She ran.

Down the stairs, through the hallway, into her bedroom, slamming the door behind her. She sat on the edge of the bed until dawn, listening for tapping.

It didn’t come again.

The next morning, she returned to the attic.

The thirteenth window was gone.

Only the dormer remained, sunlight spilling through it onto dusty floorboards.

She told herself she had imagined it. Stress. Lack of sleep. Old houses played tricks.

But that night, the tapping returned.

This time, it came from the kitchen.

Lisa crept down the hallway, gripping a flashlight. The tapping grew louder, faster, almost eager. She flicked the light on.

The kitchen window was normal.

But beside the refrigerator, where there had never been a window, the wall bulged outward. The paint cracked. A thin line split down the center, widening slowly, revealing glass beneath.

A new window.

The thirteenth window.

Fog swirled behind the glass, thick and gray. Something moved within it—closer now, clearer. A face pressed against the pane, pale and stretched, eyes too large, mouth too wide. Its breath fogged the glass from the inside.

Tap. Tap. Tap.

Lisa stumbled back, knocking over a chair. The face followed her movement, sliding along the glass like it was pressed against a thin membrane.

Tap. Tap. Tap.

She fled the kitchen, slamming the door behind her.

The tapping continued, muffled but persistent.

She didn’t sleep.

By the fourth night, the thirteenth window appeared in the hallway.

By the fifth, in the bathroom.

By the sixth, in her bedroom.

Always fogged. Always with the same pale figure behind it, tapping softly, patiently, as if waiting for her to answer.

She tried covering one with a blanket.

The blanket bulged outward, stretching, straining, until the fabric tore and the glass reappeared.

She tried hammering boards over another.

The boards warped, bent, and snapped, falling to the floor as the window pushed through the wall again.

She tried ignoring them.

The tapping grew louder.

And louder.

And louder.

Until it became a constant pulse in the house, like a heartbeat she couldn’t escape.

On the seventh night, the tapping stopped.

The silence was worse.

Lisa walked through the house slowly, flashlight trembling in her hand. Every room had a thirteenth window now—each one fogged, each one holding the same pale figure, motionless, watching her.

She reached the living room.

The largest window yet filled the entire wall, stretching from floor to ceiling. The fog behind it churned like storm clouds. The pale figure stood in the center, clearer than ever.

It raised its hand.

And tapped once.

The glass cracked.

A thin fracture ran across the pane, branching like a spiderweb.

The figure tapped again.

The crack widened.

Fog spilled through the fracture, curling into the room like smoke.

Lisa backed away, heart hammering.

The figure pressed both hands against the glass.

Tap. Tap. Tap.

The pane shattered.

Fog exploded into the room, swallowing her in cold, choking mist. She stumbled blindly, coughing, reaching for the door—but the fog thickened, clinging to her skin, pulling at her clothes.

A hand closed around her wrist.

Long fingers. Too many joints.

She screamed, but the fog swallowed the sound.

The figure emerged from the mist—taller than she expected, its limbs bending wrong, its face stretched into a wide, unnatural grin.

It leaned close.

Its breath was ice.

“You finally answered.”

The fog surged forward, wrapping around her, pulling her through the broken window frame. She felt herself dragged into the cold, into the swirling gray, into a space that wasn’t a room at all.

The thirteenth window sealed behind her.

The next morning, the house on Wren Road had twelve windows again.

All neat. All ordinary.

A real estate sign appeared in the yard by noon.

By evening, a young couple walked through the house, admiring the cozy rooms and quiet neighborhood.

They didn’t notice the faint fogged outline on the living room wall.

They didn’t hear the soft tapping that began as they left.

Tap.

Tap.

Tap.
