I thought my neighbor’s wife was hiding an affair. Then she revealed who the man really was. The truth was far more complicated than I imagined.

Then he walked out.

That afternoon, Michael contacted me.

We met in a quiet park.

When I saw him in person, I couldn’t tell whether I was looking at Mark.

Michael handed me a folder.

Inside were photographs.

Bank records.

Property documents.

And several recordings.

“You wanted to know the truth,” he said.

I opened the first file.

My neighbor, Mr. Lewis, appeared on video.

He looked frightened.

He said:

“Mark knows what happened twelve years ago. He knows Michael didn’t start the fire.”

I looked up.

Michael was watching me.

“What happened?”

Michael swallowed.

“Mark started it.”

My heart sank.

Then he said the sentence that changed everything.

“But I didn’t come back for revenge.”

“Why did you come back?”

“Because Mark is planning to do it again.”

I stared at him.

“Do what?”

“Kill someone.”

“Who?”

He looked directly into my eyes.

“His wife.”

I couldn’t breathe.
