We are a nation obsessed with true crime podcasts.

It started with the first series of Serial in 2015, which followed the story of student Hae Min Lee’s murder. Listeners were hooked to the relentless investigative reporting on a real-life story full of inexplicable plot holes, unexpected twists and many imaginative theories.

Part of the fascination was, arguably, the fact that the case was still ongoing and that we might not ever know for sure what happened. This kind of curiosity is what kickstarted the trend for true crime podcasts, with more recent favourites including Casefile, Girl Taken and The Teacher’s Pet.

Last year, The Missing Crpytoqueen became one of the most gripping unsolved mysteries. And a new episode, which further unravels the mystery, has reignited our fascination.
