The paradise island of Koh Tao exploded into public view in 2014, after the murder of two young British backpackers Hannah Witheridge and David Miller. Several other young British backpackers have also died on the island, many under suspicious circumstances. In 2015, Christine Annesley (23) travelled to Koh Tao for a holiday. Six days later she was dead. Her father Boyne Annesley, has been on a crusade ever since to find out what happened. Was her death suspicious – as he believes – or a terrible accident? By exploring the case of Hannah and David’s murders, while unravelling the island’s other tragic deaths, ‘Death on the Beach’ asks whether this is a story of paradise lost.
