There's disaster and delight for Ross Poldark and co in an action-packed episode…

Fans won’t want to miss tonight’s excellent episode – the only snag is we can’t tell you why it’s so superb, as we’ve understandably been sworn to secrecy on some big plot developments so as not to spoil things for viewers.

What we can reveal is that disaster strikes at Wheal Grace, it looks like the end of the road for star-crossed couple Caroline and Dwight, lovely Verity has some good news, and Demelza isn’t a happy bunny at all when she discovers Ross has sold their shares in Wheal Leisure and given the money to her love rival Elizabeth.

Meanwhile, George steps up his game to win Elizabeth’s hand in marriage – will it work?
