As time looked to be running out, Steve Wilkins (Luke Evans) made a huge breakthrough in his investigation into John Cooper (Keith Allen) on the latest episode of ‘The Pembrokeshire Murders’.
If you want to avoid spoilers, stop reading this article now.
The episode opened with Steve being interviewed by Jonathan Hill (David Fynn) while Cooper watched on television from prison. We then saw Andrew Cooper (Oliver Ryan) found down by the train tracks and he was alive.
In prison Cooper went to the library where he picked up a book called ‘Traces of Guilt’. Cooper’s reading habits were reported back to Steve and the team, and they were pleased their ploy was working. The team had also been given interview dates and Steve told them to prepare so they could catch Cooper.
