The Pembrokeshire Murders is a three-part drama series. It’s based on the true story of Welsh serial killer, John Cooper. The hunt was aided by an appearance that the serial killer made on the popular Bullseye programme on ITV, in 1989. Mary McGill previews part one beginning on Virgin Media TV this Thursday.
