This is the final part of our investigation into the story of ‘Operation Julie’, which was a UK police investigation into LSD production by two drug rings during the mid-1970s and resulted in the break-up of one of the largest LSD manufacturing operations in the world.

In this last episode, Stephen talks about wrapping up his undercover work in LLanddewi Brefi and planning to take part in the joint police raids which will target 87 properties in Wales and England, bringing down the different LSD production gangs.

But what happened to ‘Smiles’ and will Stephen see him again? Also what was life like for Stephen after the operation was over? What did he do next? Was he affected by living as a different person for so long?
