I'm a Substitute Husband

Chapter 7 – The Box Beneath the Silence

Ethan’s POV

The parlor smelled of dust and lilacs, untouched by sunlight or memory. Curtains drawn. Lamps off. The piano stood in the center of the room like a sleeping beast, its keys covered, its frame draped in old silk.

I hadn’t been in this room since our sham wedding day.

The housekeepers avoided it. Isabella had once said her mother used to play every night until her fingers bled—but no one had touched it since her death. I hadn’t asked why.

Now, I approached the piano like it was holding a live wire beneath it.

The silk rustled as I lifted the edge, exposing the piano’s legs and underside. At first, I saw nothing but polished wood and shadows.

Then I noticed the smallest irregularity beneath it—one of the floorboards wasn’t aligned with the others.

Crouching down, I ran my fingers along the edge. A whisper of a click, and the board popped up, revealing a hidden compartment no bigger than a shoebox.

Inside it: a single black velvet box and an envelope.

I didn’t open them there. Some part of me said don’t. Not in this house. Not with cameras potentially watching—even the ones I hadn’t found yet.

I took them back to my room.

Locked the door.

Pulled the curtains tight.

Only then did I sit on the bed, heart pounding, and open the envelope.

---

To Ethan, if you’re reading this...

I froze.

My name.

In handwriting that felt oddly familiar. Feminine, sharp, rushed.

My name. Not Isaac. Not “dear son.” It said Ethan.

How did she know me?

I kept reading.

“There are secrets even love can’t bury. I made choices to protect the wrong people. Your brother is not who he thinks he is. You are not who you think you are. If they knew you survived... they'd kill you all over again.”

“You were meant to replace him. But you became more.”

“Please, forgive me for leaving you in the dark. I only ever wanted you to have a life. A real one. Not the one they wrote for you.”

“If you’re brave enough, open the box. But once you do, there’s no going back.”

It wasn’t signed.

Not with a name. Just one word:

“Mother.”

My hands trembled as I reached for the velvet box.

It was heavier than it looked. Not just physically. Emotionally. Like it carried the weight of twenty years of betrayal.

Inside: a stack of photographs, a flash drive, and a crumpled document labeled Confidential – Project D8-94 – Subject E.

I stared at that label. Then at the photos.

The first one was of me. Or... someone who looked exactly like me. Hooked up to machines. Tubes in his arms. Wires taped to his temples.

The timestamp was from 18 years ago.

I wasn’t even born 18 years ago—was I?

I flipped through more photos. Some had a young Isabella in the background, playing in a lab room. Others showed two boys—one who looked like my brother Isaac. And the other...

Me.

Or someone who looked like me.

No. Not looked like me.

Was me.

I barely registered pulling the flash drive out and plugging it into my encrypted laptop. My hands moved without command. My mind... spiraled.

The folder opened to a single video file.

I clicked play.

The video was grainy. The camera focused on a surgical table.

My heart stopped when the doctor spoke.

“Subject Ethan is showing advanced cognitive acceleration. Memory recall at 91%. Emotional adaptation 30% slower than Subject Isaac. Begin sensory testing.”

I heard a child cry. Me.

The doctor continued. “Prepare Ethan for transference protocols. Isabella Lancaster will arrive in thirty minutes.”

I hit pause.

I couldn’t breathe.

What the hell was this?

Was I... a clone? A replacement? An experiment?

Was any of my life real?

I stood, pacing, my fists clenched. The letter. The name. The resemblance. My memories—my lack of early memories. Everything fell into a pattern I didn’t want to believe.

Someone had erased my past. Given me a role. A name. A life that wasn’t mine.

I was a substitute in more ways than one.

I tried to make sense of it all, but every thought bled into the next—blurred, distorted, unreal.

What was Project D8-94?

Why did Isabella’s mother write to me?

And what did she mean by “You were meant to replace him”?

I stared at the flash drive, as if willing it to burn a hole through my desk.

I needed answers. And I knew exactly where to start.

An hour later, I was standing outside the old Lancaster library. The estate had many wings, but this one was rarely used, left to gather dust and shadows. The door creaked open, the scent of aged paper and varnished oak thick in the air.

I knew from my early days here that the family kept private archives—ledgers, reports, even medical records. I was banking on one thing: that the Lancasters, obsessed as they were with control, would have kept something about Project D8-94.

And I was right.

Behind a shelf of old financial statements, I found a narrow drawer labeled Genetic Research - Legacy Binders. It was locked, but a firm twist of my knife cracked it open.

Inside were files. Dozens of them.

And near the back—red ink, bold letters:

D8-94: Lancaster Genetic Enhancement Protocol

I pulled it free, breath shallow.

The file was thick. Several pages referenced subjects labeled E, I, and X. The name Ethan appeared multiple times under Subject E. Test results. Mental aptitude charts. Physical conditioning.

One page chilled me to my core:

Observation Summary: Subject E shows potential for emotional depth and loyalty far exceeding Subject I. Recommending full memory wipe and implantation protocol. If surrogate project fails, Subject E may assume Subject I’s role without detection.

I stopped reading.

Surrogate?

Implantation?

Did that mean what I thought it did?

Footsteps behind me.

I spun, heart thundering—only to find Isabella standing in the doorway, her eyes burning with something between fury and fear.

"You weren't supposed to find that," she said, voice tight.

I held the file up. “Then why leave me a map?”

She stepped closer, arms crossed. “I wanted you to be ready before you saw the truth.”

I met her gaze. “Am I him, Isabella? Your ex-fiancé? Was he a... was I made to replace him?”

Her breath caught. “No. Not replace. You’re not him. You’re... more.”

That single word hit harder than any lie.

More.

And less.

She reached into her coat and pulled out another folder. “You’re not just a substitute husband. You're the only person who wasn’t born into this madness. You were created to end it.”

“What does that even mean?”

Isabella stepped closer. “My father funded a genetic project. His goal was to create the perfect heir. But you... you were never supposed to feel. And yet, you do. That’s why they buried you.”

She held up a photo from the folder. It was me, as a child, smiling. With her beside me.

“You saved me once before,” she said quietly. “Now you have to save yourself.”

I shook my head. “I don’t even know who I am anymore.”

She looked at me with more softness than I’d ever seen in her eyes.

“Then let me help you find out.”
