Season four of this much-loved British 18th-century period drama has been marked by a slew of terrible deaths. It’s made for a macabre season as Ross Poldark (Aidan Turner, pictured) struggles to balance his time as an MP for Cornwall in London and his relationship with wife Demelza (Eleanor Tomlinson). Will tonight’s finale (which feels like it has come around much too quickly) lean into more darkness? The odds are on it will. Rest assured, there are no spoilers ahead, with the finale’s plot kept under close wraps. All that remains to be seen is if we’ll be left with tears of heartbreak or redemption.
