Pembrokeshire is a safe and secure place to live. But for a time in the 1980's, the feeling for many was different. Two violent murders once again had communities in fear. But for some, these latest crimes had parallels with Ffynnon Samson. And questions began to be asked as to whether the same person could be responsible.

In this episode we meet Aled Scourfield - the reporter who first learned about these crimes at the trial of a man called John Cooper. A man who is now in prison for multiple murders. It was Aled who, after hearing rumours of a link, first asked whether Cooper might have been in Llangolman back in 1977. Whether John Cooper might have found his way to the remote farmhouse, and face to face with Griff and Patty. It's a question which has divided this community... a theory which lacks any evidence. But for some it's more compelling the closer that you look.
