Chapter 1
The day I planned to ask Vanessa to marry me, my seven-year-old daughter screamed that someone was trapped behind a door at the bottom of our swimming pool.
At first, I thought she was imagining things.
Then I saw the door myself.
And what happened next changed everything I believed about the woman I loved.
It was a beautiful Saturday afternoon in Atlanta.
Our backyard was filled with white flowers, sparkling champagne glasses, and nearly eighty guests.
I had spent three months planning the celebration.
Vanessa thought it was an ordinary party.
She had no idea I was about to propose.
At least, that was what I believed.
I stood beside the swimming pool, wearing my favorite royal-blue suit.
Vanessa looked stunning in her fitted red gown.
Her long black hair fell over her shoulders, and her smile seemed bright enough to light the entire garden.
I reached into my pocket.
My fingers closed around the small velvet box.
"Vanessa," I said, taking her hand. "These past two years have changed my life."
She smiled.
"Oh, Marcus."
The guests moved closer.
Someone began recording.
I lowered myself onto one knee.
Vanessa covered her mouth.
I opened the ring box.
Inside was a diamond engagement ring worth nearly thirty thousand dollars.
I had chosen it because Vanessa once told me she dreamed of wearing a ring just like it.
"Will you—"
"DADDY!"
A small figure suddenly pushed through the crowd.
My daughter, Lily.
She was wearing her pale-pink party dress, with her long braids bouncing against her shoulders.
Her face was white with fear.
She grabbed my arm so hard that I nearly dropped the ring.
"Daddy! There's a door under the pool!"
Several guests laughed nervously.
I blinked.
"What?"
Lily pointed toward the deep end.
"There's a DOOR down there!"
Vanessa's smile vanished.
"Lily, stop ruining this!"
My daughter ignored her.
She pulled on my sleeve.
"Daddy, please! I saw something move!"
Vanessa grabbed Lily's shoulder.
"That's enough. You're embarrassing us."
I stood immediately.
"Vanessa, let her go."
She released Lily, but her expression remained furious.
"Marcus, she's making things up again."
I looked at my daughter.
Lily had always been imaginative.
She loved mysteries, hidden passages, and adventure books.
But this wasn't excitement.
This was terror.
Her hands were trembling.
"Daddy," she whispered, "somebody's inside."
A strange chill moved through me.
I followed her finger toward the water.
At first, I saw nothing except sunlight reflecting across the blue tiles.
Then something caught my attention.
Near the deep end, partially hidden beneath a decorative stone overhang, was a dark rectangular shape.
I frowned.
Our pool had been renovated six months earlier.
Vanessa had supervised most of the work because I was traveling for business.
I knew about the new tiles.
The waterfall.
The lighting.
But I had never heard about a door.
I stepped closer.
My stomach tightened.
There was definitely something beneath the surface.
Something that didn't belong there.
"Marcus," Vanessa said sharply. "Come back."
I ignored her.
I leaned over the edge.
Through the clear water, I could just make out two vertical wooden panels.
They looked old.
Much older than the rest of the pool.
Then I saw something move.
Not a fish.
Not a shadow.
One of the metal handles shifted.
My blood went cold.
"Lily," I said quietly, "where did you see this?"
She pointed.
"I was looking for my bracelet. I dropped it near the pool."
She swallowed.
"Then I saw the door. And something moved behind it."
I looked at Vanessa.
Her face had gone pale.
"Did you know about this?"
She shook her head too quickly.
"Of course not."
"Then why are you scared?"
"I'm not scared!"
Her voice rose.
"Marcus, don't be ridiculous. It's probably some old decoration."
I turned back toward the water.
The handle moved again.
There was no current strong enough to explain it.
Something was touching that door.
From the other side.
I snapped the ring box shut and placed it in Lily's hands.
"Hold this."
"Daddy?"
I pulled off my suit jacket.
Vanessa rushed toward me.
"What are you doing?"
I handed my jacket to the nearest guest.
"I'm checking."
"No!"
Her shout stopped several conversations.
I turned.
She was staring at the pool as though it contained something deadly.
"Marcus, please. Don't go down there."
"Why?"
She opened her mouth.
Nothing came out.
That was enough.
I kicked off my shoes.
Then I dove.
Cold water swallowed me.
I opened my eyes and swam toward the deep end.
My white shirt ballooned around my chest.
The royal-blue fabric of my trousers dragged against my legs.
I kicked harder.
As I approached the stone overhang, the strange shape became clearer.
Two enormous wooden doors.
Their dark surfaces were reinforced with rusty metal bands.
They had been built into the concrete wall.
I couldn't understand how they were still intact underwater.
Then I noticed something even stranger.
The wood wasn't rotting.
Someone had maintained it.
Recently.
I reached for the handles.
They were heavy and cold.
I pulled.
Nothing happened.
I tried again.
Then the left handle twisted.
Not because I moved it.
Because someone on the other side was turning it.
I jerked backward.
My heart slammed against my ribs.
A thin stream of bubbles escaped around the doorframe.
Above me, I could hear muffled screams.
Then Lily's voice cut through the water.
"DADDY! DON'T OPEN IT!"
I looked up.
She was kneeling beside the pool, crying.
Vanessa stood behind her.
Even through the water, I could see her expression.
She wasn't confused anymore.
She was terrified.
I turned back toward the doors.
A narrow black line appeared between them.
The opening widened.
One inch.
Then two.
Something pale moved inside the darkness.
I kicked backward.
My lungs were burning.
Then I heard three heavy knocks.
Slow.
Deliberate.
May you like
Someone was alive behind those doors.
And before I could decide what to do, a human hand reached through the opening and grabbed my wrist.
