INT. FAMILY HOME - HALL - LATE AFTERNOON
Theo kneels at a child-sized wooden door with an old brass key poised at its lock. Mara enters carrying the last packing box and stops cold.
The packing box slips against Mara's hip.
Mara
Tell me that is a bottle opener.
Theo
It opens something. So, technically, you are very close.
Mara
Mom said there was no door under the stairs.
Theo
Mom also said the wall was solid. Solid walls do not usually have hinges, Mara.
Mara
Put the panel back. The estate agent gets here in eighteen minutes, and we are not explaining secret carpentry to a stranger.
Theo
Great. Then we have seventeen minutes to find out why everybody lied.
Mara
Nobody lied. It is probably an old coal cupboard.
Theo
With our initials carved over the lock? Yours first, mine underneath, in Dad's handwriting?
Mara
You do not know it is his.
Mara
I do not need to. That key turns twice, then sticks. You will snap it.
Theo
Interesting thing to know about a door that does not exist.
Theo
Ask properly. Like I am a person in this family, not a smoke alarm you can take the batteries out of.
Mara
Theo, please give me the key.
Theo
Please tell me where it was before I found it sewn inside Dad's green coat.
Mara
That coat went to the charity shop last winter.
Theo
No. A bag went to the shop. You moved the coat into the attic and hoped I would stop looking.
Mara
I hoped we could move without turning every box into an investigation.
Theo
I hoped my sister would not hide evidence in the insulation. We are both disappointed.
Mara
I opened it once. Last January. That is what you want me to say, yes? I opened it, and I shut it again.
Mara
Promise you will not turn this into one of your theories about tunnels, time machines, or Dad living behind the boiler.
Theo
No. You do not get to make me promise the correct reaction before you give me the truth.
Mara
Stairs. Going down farther than the cellar, even though the cellar ends right there. And I could hear a train.
Theo
There has not been a railway near this house for sixty years.
Mara
I know. I could still smell the hot metal. Then I saw the platform where Dad left us, exactly as it was that morning.
Theo
You saw it through the door?
Mara
Not like a picture. The hall stretched until the wallpaper became station tiles. For one second, this house and that platform were the same place.
Theo
And you went down those stairs alone anyway. That is either incredibly brave or the most Mara decision ever made.
Mara
I saw his suitcase. I heard myself yelling from the car. I shut the door before I had to hear the rest.
Theo
So you decided I could never know.
Mara
You were nine. You still left the porch light on for him. What was I supposed to do, invite you downstairs to watch him leave twice?
Theo
You were twelve. Why does everyone act like turning twelve made you the emergency parent?
Mara
Because somebody had to notice when you needed dinner. Somebody had to stop Mom crying long enough to sign your school forms.
Theo
And somebody should have told you Dad's suitcase was packed before you yelled at him.
Mara
You do not remember that morning.
Theo
I remember hiding behind the coats. I remember him checking the train time before you came downstairs. You did not make him go.
Mara
Mom said you slept through it.
Theo unfolds a square of paper worn soft at the creases.
Theo
Mom says things when the truth has sharp corners. She also put this in the lining.
Theo
Only about forty times. The door opens for two. It shows the truth one person cannot carry alone. Her words, not Dad's.
Mara
She knew I opened it.
Theo
I think she was waiting for you to stop going down there by yourself.
Mara
(barely above a whisper)
If it shows that platform again, I may not be able to move.
Theo
Then I will be extremely annoying until you do. It is my most developed skill.
Mara
One turn each. If anything feels wrong, we close it. No arguments.
Mara covers Theo's hand with hers. The key turns once, then twice. From beyond the door comes the rush of a distant train, followed by the soft crash of waves. The siblings look at each other before the latch lifts.
Theo
One turn each. And this time we both get to remember what happens.
