Get the full story of the sinister serial killer

The drama about real-life serial killer Charles Sobhraj, who murdered travellers on the so-called Asian hippie trail during the 1970s, reaches its halfway point on BBC1 this week. If you can’t wait to see how the story pans out, or are in need of a recap (it’s true that the timeline jumps around a lot, often making it a little difficult to follow), the entire series is available as a boxset. Tahar Rahim plays the icy-cold murderer, with Jenna Coleman (pictured, left, with Rahim) as his lover and Billy Howle as the diplomat who’s intent on tracking them down. BBC iPlayer, available now
