Nearly twenty years ago the half-naked body of a Thai woman was found by walkers in a remote part of the Yorkshire Dales in England. The autopsy proved inconclusive, and an inquest failed to reveal how she died. For over a decade her identity remained unknown, her body buried in a grave marked 'The Lady Of The Hills'. The thirty-six-year-old was one of thousands of Thai women who marry foreign men every year. In 2016, after a review, her case was reopened as a homicide investigation. BBC Thai journalist Issariya Praithongyaem asks why no one in the UK reported this mother of three missing? And why hasn't anyone been brought to justice for her death.
