He admitted that he had known I might be capable of moving more than Amanda believed.

He admitted that the financial pressure had made him desperate.

Then the interviewer asked whether he accepted responsibility for pushing me into the lake.

A long silence followed.

Finally, Derek answered.

“Yes.”

I felt my chest tighten.

It was the first time I had heard him say the truth plainly.

The interviewer asked whether anyone had forced him to do it.

Derek said no.

Then he added something that made Leah sit upright beside me.

“There’s something else about the money.”

The interviewer asked him to explain.

Derek hesitated, then said that the eleven million dollars had become the center of arguments between him and Amanda.

He claimed Amanda had begun questioning whether he would actually inherit as much as he expected.

He also said they had worried that I might change my estate plans before my death.

I listened carefully, remembering how often Amanda had asked me to reveal the location of my original trust documents.

The interviewer asked whether Derek had seen those documents.

He said that he had seen copies.

Then he admitted that some of the papers they relied upon were not genuine.

I looked toward Leah.

We had long suspected that the statement attributed to me was false.

But Derek was now describing its preparation.

He said Amanda had used my genuine signature as a model and that he had witnessed a document I never authorized.

The interviewer asked why they needed it.

Derek answered that it would help explain the lake incident as something I had wanted.

I felt anger rise through the numbness.

He had finally admitted the purpose of the lie.

Then the interviewer asked who first suggested preparing the false statement.

Derek hesitated again.

For several seconds, I heard only the faint hum of the recording equipment.

Then he said, “It was my idea.”

Leah looked at me.

I stared at the speaker.

Derek continued, describing the way he believed the forged document would protect him if anyone questioned the circumstances of my death.

He said Amanda helped prepare it, but he was the one who wanted it completed before the trip.

The interviewer asked whether his mother had ever expressed a wish to die.

Derek answered quietly.

“No.”

The word seemed to echo inside my chest.

For weeks, I had been forced to defend myself against a false account of my own wishes.

Now my son was admitting that he knew I wanted to live.

The interviewer continued.

“Then why did you tell the police she deliberately went into the lake?”

Derek’s voice broke.

“Because I pushed her.”

I covered my face with my hands.

There was no triumph in hearing the confession.

There was only the terrible confirmation of something I had known from the moment the wheelchair left the dock.

Then Derek began crying.

He said he was ashamed and that he could not sleep without hearing the sound of the chair hitting the water.

He described seeing me sitting helplessly before him and remembering how I had taught him to swim.

He said he had wanted to stop, but the debts and the fear of losing everything had overwhelmed him.

For a moment, I found myself crying with him.

Not because I believed his explanation excused anything, but because I could finally hear the grief he had hidden beneath his lies.

Then the interviewer asked a final question.

“Mr. Mercer, are you telling us everything you know about the documents and the inheritance?”

Derek went silent.

The recording continued long enough for me to hear him breathing unevenly.

Then he said, “There’s one thing Amanda doesn’t know.”

I looked up.

The interviewer asked what he meant.

Derek replied that before the lake trip, he had discovered something about my estate that changed his understanding of the eleven million dollars.

He said he had not told Amanda because he was afraid she would refuse to continue with the plan.

My stomach tightened.

For months, I had believed they were both pursuing the same fortune.

Now Derek was claiming he had concealed something important from the person who helped him plan my death.

The interviewer asked him to identify the document.

Derek answered that it was a copy of a notice concerning changes to my estate arrangements.

Then he said something that made Leah grab the edge of the table.

“I knew my mother was about to stop me from inheriting.”

I stared at the speaker.

He continued before the interviewer could respond.

“She didn’t know I’d found out.”

My thoughts raced back through the final weeks before the lake.

I remembered Leah warning me that Derek and Amanda were asking increasingly urgent questions about the trust.
