Were excited about it now.
These are complicated tales, and they often span out over years.
Its a wonderful opportunity for us to tell the story in a more fulsome way.
And I think its great for the listeners to really understand what the deal is all about.
So will you focus on one case per podcast season?
It takes a lot of surprising twists and turns and has at the center a very strange character.
Weve been following this one for a while, and its ideal for this kind of treatment.
Thats why were doing it.
And then well move on to somebody else and I suspect itll be a similar kind of thing.
Well pick our most interesting tales and live in them as much as we can.
Ill be telling the story, but so will producers who worked on the program.
Have you noticed your voice changing a little now that youre doing a podcast?
Is your presentation a little different?Maybe unconsciously.
Theres more of me, which is probably not necessarily a good thing.
But also Im conscious of the fact that it cant rely on the pictures to tell the story.
Theres so much true-crime out there.
I have to wonder if youve thought there would be over-saturation.
Can there be too much?I am always prepared for that possibility.
Who knows, tastes change.
I had to be dragged into it in the first place.
I really like it now.
People are very nice to me and I am a lucky guy.
