Help finding a podcast

[sadhippo]

I was recently recommended a podcast on my home page that seemed interesting but I forgot to add it to my library and I can't remember the title.

I know the title had a colon ( : ) in it and in the description it mentioned a book of the same name. I also know it mentions murders or crimes that are related to the book. I think it would be categorized as true crime. Any help in identifying this podcast would be really appreciated.
