In the seventh of nine episodes George learns of a vacant seat in Parliament for a Member of Truro and decides to pursue it. Elizabeth and Agatha prepare for Agatha’s 100th birthday party, to George’s chagrin, and Caroline hosts a fake wedding reception to which the great and good are invited.
George fails to impress Falmouth at the reception, and instead decides to ally himself with Sir Francis Basset, who plans to challenge Falmouth’s monopoly in Truro.
Hugh Armitage makes his affection for Demelza apparent but Ross – foolishly – dismisses it. Meanwhile, Sam becomes infatuated with Tholly’s daughter Emma Tregirls, and Morwenna’s sister Rowella arrives at the Whitworth vicarage, having been sent for by Osborne to help his pregnant wife.
Basset invites Ross and Demelza to Tehidy, where Hugh’s attentions again find Demelza – as Basset voices a proposition to Ross.
