From This American Life, Serial Podcast has been one of my favourite listens since the first season released last year; highlighting the disappearance of Baltimore student Hae Min Lee and the arrest of her 17 year-old boyfriend, Adnan Syed, for her ultimate death. Narrator Sarah Koenig investigates the story on a first-hand basis and goes through hours of evidence and recordings with which she attempts to paint a picture for listeners. Did he do it? I still can't make up my mind.
For those who are hooked (I definitely recommend listening to the first season before starting the second - listen in order), the second season is already underway and the story is different and of much greater scale - in my opinion. This season follows the developing story of Bowe Bergdahl, a U.S. soldier stationed in Afghanistan who claims to have walked off his base, where he was captured and held by the Taliban for over five years.
I don't want to spoil anything, so listen, here.
