Go on admit it...... as soon as you see a Cornish tin mine you immediately think of Ross and Demelza. There can't be many people who have not either seen the original TV series, the current TV series or not read the books.
Kitty and I are not great TV watchers we only ever watch the news (otherwise known as "What the government and the BBC would like you to believe"), however we have several friends who are working as extras in the current Poldark series and we always watch to see if we can spot them. :)
