It’s the true-crime BBC drama that’s taken over our screens this new year, one that’s actually based on the events of a murderer who targeted backpackers throughout Asia in the 1970s, along what was called the ‘hippie trail’. While The Serpent might be giving us a dose of lockdown entertainment (of the intense kind, you might want to switch between Bridgerton when it gets too much), the story of what really happened to killer Charles Sobhraj and his accomplice Marie-Andrée Leclerc is a gripping one.
