Back in the seventies I watched ''Poldark'' on television: it was enjoyable, but I'll confess that if I'd missed an episode it wouldn't have worried me too much. When the gentleman rebel reappeared in 2015 I had no intention of watching, but a friend saw the first episode and said how good it was. I caught up on iPlayer, almost for politeness - and was hooked. It wasn't just the story - but perhaps I'm more in tune with it now that I was forty years ago - it was the quality of the production which kept me watching week after week. When Emma Marriott's book landed on my desk the temptation to 'just have a quick look' proved far too much for me.
