I've never listened to a podcast so I find that part of the story to be intriguing. I can't imagine sitting and just listening.
The story sounds like it rides the edge between thriller and horror. Not sure if I will enjoy it if it goes over the edge into evil, demonic type stuff.
One of my favorite fictional characters is someone who uses forensics to solve crimes and I find that to be very interesting. I'd love to see an author approach that with a new character and see things through her eyes.
