I usually record it and watch it one afternoon in the week when wife and I are on our own but the identity of the balaclava man will be all over the papers and tv tomorrow so must watch it this evening as it happens.
Just looked at BBC Player and prior to this series there is a synopsis of all that has happened up to the start of series 3. It is tiled Everything You Must Know before watching series 3
I have recorded this series as I dint realize there had been a previous couple of series. Do I need to watch those 2 series before the latest or are they individual stories so that it wouldnt matter?
