Chapter 1: The Door Beneath the Water
“Daddy, please hurry! Mommy's crying underneath the swimming pool!””
My four-year-old daughter was shaking so violently that her little pink sandals slipped against the marble patio.
I had heard Ava say strange things before. Imaginary monsters lived in her closet. A little girl sometimes waved at her from the upstairs hallway. Once, she insisted someone had been singing to her through the bathroom drain.
But this was different.
Because her mother had disappeared four years ago.
And nobody had ever found her body.
“Sweetheart, come here.”” I crouched and held Ava's shoulders.
“Tell Daddy exactly what you heard.””
She pointed toward the swimming pool.
“Mommy was crying. She said my name.””
My throat tightened.
Danielle.
My wife.
The woman who vanished eighteen days after giving birth to our daughter.
Police discovered her abandoned SUV near the Savannah River. Her phone was smashed, her purse was missing, and there were traces of blood on the driver's seat.
The investigators eventually declared her presumed dead.
I never received a body to bury.
For four years, I had lived with that unfinished goodbye.
“Maybe you were dreaming, sweetheart,” I whispered.
Ava shook her head.
“No, Daddy. She said she wants you to open the door.””
Before I could ask another question, Vanessa appeared from the back entrance.
“AVA! STOP!””
Her voice cracked across the patio.
Ava immediately ducked behind me.
Vanessa hurried toward us, clutching a glass pitcher filled with pink lemonade.
“What is happening?”” she demanded.
I stood.
“She says she heard Danielle underneath the pool.””
Vanessa's expression changed.
Not gradually.
Her entire face seemed to lose its color.
Then she laughed nervously.
“Marcus, she's four. Children invent things.””
“She's been saying this for three nights.””
“Then stop encouraging her!””
I stared at my fiancée.
Vanessa had entered our lives eighteen months earlier. She worked in medical administration, had impeccable manners, and seemed unusually patient with Ava.
She remembered every birthday.
She bought Ava dresses.
She even insisted that we preserve Danielle's photographs rather than put them away.
I had mistaken all of that for kindness.
“Why are you so upset?”” I asked.
Vanessa placed the lemonade pitcher on the patio table.
“Because we're getting married in three weeks, Marcus. I don't want your daughter growing up believing her dead mother is hiding beneath a swimming pool.””
Ava grabbed my fingers.
“But Mommy isn't dead.””
Vanessa turned sharply.
“Enough!””
Ava began crying.
Something inside me hardened.
“Don't speak to her like that.””
Vanessa stared at me for several seconds before forcing a smile.
“I'm sorry, sweetheart. I just don't want you frightened.””
She kissed Ava's forehead.
My daughter flinched.
I noticed.
And for the first time, I wondered why.
“Daddy,” Ava whispered, “I can show you where Mommy knocks.””
She pointed toward the deepest end of the pool.
I grabbed my diving mask from the outdoor storage cabinet.
Vanessa stepped directly in front of me.
“Marcus, don't be ridiculous.””
“Move.””
“There's nothing down there.””
“Then you won't mind me checking.””
Her fingers closed around my wrist.
“Please. Don't.””
I looked down at her hand.
“Why?””
She released me immediately.
I jumped.
The water was cold enough to steal my breath. I swam toward the deepest section, following the pale blue tiles until I reached the bottom.
At first, I saw nothing unusual.
Then something caught my eye.
A metal drainage cover was sitting crookedly near the pool wall.
I pulled it aside.
Behind it was a rectangular metal surface, partially concealed beneath the concrete structure.
I brushed away the algae.
My heart nearly stopped.
It was a hatch.
A heavy steel hatch with a brass keyhole.
There were scratches around its edges, as if someone had repeatedly tried to force it open from the other side.
Then I heard something.
Three knocks.
Slow.
Deliberate.
I nearly swallowed water.
I kicked toward the surface and emerged gasping.
Vanessa was standing beside the pool, her hands pressed against her chest.
“Well?”” she asked.
I pulled off my mask.
“There's a door underneath the pool.””
Her lips parted.
“Marcus…”
“Why is there a locked door beneath our swimming pool?””
She took a step backward.
Then another.
And suddenly, she screamed.
“WHO TOLD YOU ABOUT THE ROOM?””
I froze.
I hadn't mentioned a room.
I had only said door.
“What's inside that room, Vanessa?””
She looked toward the house.
“Get out of the pool.””
“Answer me!””
“Marcus, please. You don't understand.””
Behind me, Ava began crying.
Then she whispered something that made my blood run cold.
“Daddy, Vanessa says Mommy has to sleep when she hears me.””
I turned toward my daughter.
“What did you say?””
Ava wiped her nose.
“Every night, Vanessa gives me pink lemonade. She says it helps me sleep so I won't hear Mommy crying.””
I looked at the pitcher.
Then at Vanessa.
And suddenly, I remembered something.
Every evening for the past six months, Vanessa had insisted on preparing Ava's bedtime drink herself.
She called it her special nighttime recipe.
I had never questioned it.
Now, I couldn't stop thinking about the strange heaviness in Ava's eyes every morning.
“Vanessa,” I said quietly, “what have you been giving my daughter?””
She started crying.
“Marcus, please. I was protecting her.””
“From what?””
She shook her head.
I climbed out of the pool and reached for her handbag.
A brass key was hanging from a small leather loop.
The exact size of the hatch's keyhole.
Vanessa grabbed my arm.
“DON'T OPEN THAT DOOR!””
My phone suddenly rang.
Unknown number.
I answered.
A woman's trembling voice came through the speaker.
“Marcus, please don't hang up.””
I stopped breathing.
I knew that voice.
“Danielle?””
A sob.
“I'm alive.””
My knees weakened.
“Where are you? Where have you been?””
“Listen carefully. Vanessa isn't who she says she is.””
I looked at my fiancée.
Her crying had stopped.
She was staring at my phone with an expression I had never seen before.
Danielle whispered, “Four years ago, the police found a second person's fingerprints in my car.””
“Whose fingerprints?””
“The woman you're about to marry.””
Vanessa lunged for the phone.
I pushed her away.
And then Ava screamed.
“DADDY! SOMEBODY'S COMING OUT!””
I turned toward the pool.
Bubbles were rising from the deepest end.
The metal hatch was slowly opening.
And a pale hand had appeared beneath the water.
Danielle's voice became frantic.
May you like
“Marcus, whatever comes out of that room, don't let it see Ava.””
Then the call disconnected.
