It is almost fifty year since the bodies of Griff and Patti Thomas were found in their remote farmhouse in Llangolman, Pembrokeshire. And yet - exactly what happened to them, and who was responsible, is a question which still hangs over the community. Because there is the official police version of events. And then there is the other version.
This series from BBC Wales examines the case in detail. It takes listeners back to 1976, via first hand testimony from the people who refuse to forget what they saw. And it puts the evidence from the case back under the microscope. After nearly half a century, could the community finally get the justice they've been campaigning for?
