One of the most memorable drama series of my childhood (not even a teenager then!)
Like the two other reviewers I was very young at the time but it was one of the programs the family always made a point of watching. (VCRs weren't needed then as we did much less than we do now.)
Don't remember any of the details but remember how I felt about it - totally gripped, always on the edge of the seat at some stage of each believable episode.
Probably long since wiped, if it was even recorded, but would like to see it again - for a variety of different reasons: nostalgia, to see if it's as good as I remember, check out the "primitiveness" (or otherwise) of sets, production etc etc
