Chapter 1 – The Nightmare

Diana Warren reluctantly agrees to meet a man she has been talking to on the Trix dating app after weeks of conversations. Jacob Dean, her boyfriend, encourages the unusual meeting as an experiment in modern friendships.

A violent storm begins as the stranger arrives.

The chapter ends with Diana noticing that the man’s eyes seem completely devoid of emotion.

.

The first drop of rain struck the bedroom window just after eleven.

Diana Warren looked up from her phone, watching a tiny bead of water slide across the glass before another joined it, then another, until the window shimmered beneath the glow of the streetlights.

“The forecast said clear skies,” she murmured.

Jacob Dean didn’t look away from the television. “Forecasts lie.”

She smiled faintly, though the smile didn’t quite reach her eyes.

Her phone vibrated in her hand.

Outside.

The message contained only that single word.

Her stomach tightened.

She stared at the screen for several seconds before locking it.

Jacob finally glanced over.

“That’s him?”

She nodded.

For nearly a month the stranger had been nothing more than a profile on Trix. At first she’d ignored the request. His profile had been sparse—no dramatic selfies, no inspirational quotes, no endless list of hobbies. Just a single photograph of a man standing beside a lake beneath a gray sky.

His name read simply:

Adrian.

No surname.

Normally, she would have swiped past.

Instead he’d sent a message.

Most conversations online feel rehearsed.
Yours don’t.

It had been unexpectedly thoughtful.

Over the following weeks they’d exchanged messages about books, music, late-night coffee shops, and growing up in small towns where everybody knew everyone else’s business.

He had never flirted aggressively.

Never pushed.

Never crossed a line.

If anything, he’d seemed lonely.

Jacob had teased her relentlessly.

“I think you’ve accidentally made a friend.”

“I don’t need random internet friends.”

“But you’ve got one.”

She’d laughed.

Now, somehow, that harmless conversation had led here.

A knock sounded downstairs.

Not loud.

Three slow taps.

She looked toward the bedroom door.

Jacob muted the television.

“Well…”

Neither moved.

The silence stretched longer than it should have.

Another knock.

Still gentle.

Almost patient.

Jacob stood first.

“I’ll get it.”

“You don’t think this is weird?”

He shrugged into his hoodie.

“A little.”

“Only a little?”

“You’ve spoken to him every day for weeks.”

“People lie online.”

“They do.”

She searched his face for concern.

Instead she found curiosity.

“It’ll be fine,” he said. “Worst case, we have an awkward cup of tea.”

She wished she shared his confidence.

The hallway seemed unusually dark as they walked downstairs.

Outside, the rain intensified, rattling against the front windows.

The porch light cast long shadows over the wet driveway.

Jacob reached for the handle.

“You sure?”

“No,” Diana admitted.

He smiled anyway.

Then he opened the door.

The man standing outside looked almost exactly like his photographs.

Almost.

Dark hair, neatly combed despite the rain.

Long black coat.

Hands tucked calmly into his pockets.

Rainwater dripped from his shoulders, but he made no attempt to brush it away.

“Adrian?”

The man smiled.

“Jacob?”

His voice was soft.

Educated.

Measured.

“Come in,” Jacob said.

“Thanks.”

He stepped inside.

The temperature in the hallway seemed to drop.

Diana told herself it was only the cold air rushing in from outside.

Adrian glanced around the house.

Not obviously.

Not rudely.

His eyes moved with quiet precision.

Front door.

Living room.

Staircase.

Kitchen.

Hallway.

The movement was so subtle she almost missed it.

“Nice place,” he said.

“Thank you,” Diana replied.

He removed his coat carefully and folded it over one arm instead of hanging it up.

An odd detail.

People usually relaxed once they entered someone else’s home.

He looked ready to leave at a moment’s notice.

Jacob headed toward the kitchen.

“Tea?”

“That would be nice.”

As Jacob disappeared into the next room, silence settled over the hallway.

Rain drummed steadily against the roof.

Adrian turned toward Diana.

For the first time, they stood face to face.

She smiled politely.

“So… it’s nice to finally meet you.”

“It is.”

His smile arrived.

A fraction too late.

Just enough to feel practiced.

Something inside her shifted.

Not fear.

Not yet.

Instinct.

The kind that whispered before the mind understood why.

She looked into his face, searching for the warmth she’d imagined during weeks of conversation.

Instead, she found herself staring into eyes that reflected nothing.

No excitement.

No nervousness.

No kindness.

No curiosity.

Only a vast, unsettling stillness.

It was as though there was no one looking back at her at all.

And for the first time since opening the door, Diana wondered whether inviting Adrian into their home had been the biggest mistake of their lives.
