I've just finished listening to End of Days, an eight-episode podcast made by BBC Five Live and I loved it so much that I want to recommend it to everyone! It's about the British people that were caught up in the Waco cult/siege and is really sad yet fascinating.
I listened to Serial a few years ago (series 1 only so far) and was totally gripped by it, now after being similarly obsessed with End of Days I am keen to find new podcasts with a similar sort of vibe - true stories gone into in great depth. I've been browsing this board and have decided to have a crack at S---Town, but feel free to recommend me any others!
