Linda left the casserole dish behind.

I gave Martin a copy of my contemporaneous note.

He said it was a record of what I heard, not a substitute for the audio itself.

If we wanted to rely on the recording, its original and context would matter.

I asked Linda to preserve it.

Whether she would cooperate remained uncertain then.

Later, she would sign a statement about what she knew.

That mattered more than my turning a few overheard sentences into proof of everything.
