The Case of Charles Dexter Ward by the American horror writer H. P. Lovecraft is a story that only got published after his death. Now it gets a modern makeover 90-odd years after it was written.
One of the interesting things about this re-make of something written in 1927 is the way it plays around with the podcast format. There's the subject matter (it sounds like a true crime show) and there are also the formal elements like scratchy old audio, voice recordings, ads, and some clever editing and sound design.
There's also a narrative device we've seen before in shows like Serial and S-Town...the central voice of a slightly bemused, naive narrator who seems to be trying to solve the mystery at the same time as we're trying to make sense of it.
