By the end 1976, the community in Llangolman was still waiting for answers. Police officers had taken over the village, conducting their investigation into the deaths of Griff and Patti Thomas. Their work included building up a picture of their victims - learning their habits, understanding their relationship as siblings, and asking who was set to benefit from their death. And they scour the crime scene, looking for the clues and evidence which might help them to understand exactly what happened, and who was responsible. But as more information emerges, clarity remains hidden. And there's no stopping the rumour mill which is in overdrive. This episode chronicles those events from early 1977. And it tells the story of the investigation and how it was reported by local media. By the end, there's an alarming new theory which threatens to derail everything the community believed to be true.
