Its on my list this one, I followed the story, it was proper f'd up, I had absolutely no doubt he'd done it.Not a TV series but a documentary called ‘Into the Deep’.
About inventor Peter Madsen who murdered a journalist aboard the submarine he built. A 90 minute documentary describing the timeline of events, but I found the last few minutes chilling when 11 months before the murder he talks in an interview about psychopaths walking amongst us, human predators, stalkers, describing their traits. He’s talking about himself and it sent a shiver down my spine.
