Anderson Cooper

But what was amazing is that Kathy...

And even my dad, who died at a pretty young age, 65, there were so many conversations that we had never had.

And what I found was, and I don't know if you found this to be the case, but people leave clues behind.

Sometimes.

often on purpose.

They leave clues behind, the songs they loved, the books they loved, the photos they loved.

Usually it's not a diary, it's the little things.

And so I found that I was collecting all these little crumbs that had been left behind by Kathy and my dad.

My dad left behind a box of slides.

And he was in the Korean War, but I never talked to him about where he was in the Korean War.

And did he ever kill anybody?

We never talked about it, but he left these slides behind.

And using the internet, I was able to find out where these pictures of him at war were taken.

The front line.

He was on the front lines of the Korean War.

Brutal.

And I knew him as a real estate man.

But I met him as a soldier writing the book, which was amazing.

I did.

I had a really wonderful conversation with Kathy because, again, if you dig, if you look for these crumbs, I found a piece in a small local newspaper from Palm Springs where she had been part of like a weekly book club.
