Vanessa's voice came out low and careful.

"Sophie.

Go back to bed."

Sophie did not move.

Her hand was still on the handle.

"I heard her," Sophie said.

"I heard Mommy."

"You had a dream." Vanessa stepped closer.

"Come on.

I'll get you some water."

"I wasn't asleep."

Vanessa stopped two feet away.

In the dark of the hallway, Sophie could see the shape of her — the stiff shoulders, the arms crossed tight across her chest.

Not the posture of someone offering comfort.

"Sophie." The word came out harder this time.

"Step away from that door."

Sophie knocked instead.

Three times.

Then waited.

One knock came back.

Then three.

Neither of them spoke for a moment.

Then Vanessa said, very quietly, "That is the pipes."

"You know it isn't."

Vanessa's hand closed around Sophie's wrist — not rough, but firm.

She pulled her back two steps from the door.

"Your father will explain everything in the morning," she said.

"This is not your business tonight."

"She's my mother."

"And this is my house."

Sophie looked up at her.

"It's my dad's house."

Vanessa let go of her wrist.

She didn't answer.

She walked Sophie back down the hall, one hand on her shoulder, and closed the bedroom door from the outside.

Sophie heard the soft click of the handle being held in place.

Not locked.

Just held.

She stood on her side of the door and listened until she heard Vanessa's footsteps move away toward the master bedroom.

Then she heard something else — the low sound of a voice, Vanessa's voice, speaking quickly and quietly.

A phone call.

In the middle of the night.

Sophie pressed her ear to her own door and caught only pieces.

"…she heard it.

I told you the machine wasn't enough…"

"…you need to move her before morning…"

"…Owen doesn't know yet.

He can't know yet…"

Then silence.

Sophie sat down on the floor with her back against the door.

She did not cry.

She was six years old and she had already decided that crying was not going to help her mother.

She needed her father.

She waited until the house went completely still.

Then she counted to one hundred.

Then she counted again.

She opened her door.

The hallway was dark.

The master bedroom door was shut.

At the far end, the basement door was exactly where she had left it — closed, the key gone from the hook beside it.

Vanessa had taken the key.

Sophie turned and walked in the other direction, toward her father's old study.

He kept a spare key to everything in the top drawer of his desk.

He thought she didn't know that.

She did.

The drawer was stiff.

She had to use both hands.

Inside, beneath a rubber band and a broken watch, she found a small brass key on a plain ring.

She carried it back down the hall.

She did not knock this time.

She just put the key in the lock, turned it slowly, and opened the door.

The smell hit her first — cold air and something damp.

Then the dark of the stairs going down.

She called softly into it.

"Mommy?"

A sharp intake of breath from somewhere below.

Then her mother's voice — hoarse, barely above a whisper, but completely unmistakable.

"Sophie.

Baby, don't come down.

Go get your father.

Right now.

Go get Daddy."
