Having secretly spent cash he can't afford on 'refunding' Elisabeth, Ross is desperate to prevent his second mine's bankruptcy and hence debtor's jail as George is bound to call his debts. So he agrees to smuggler Trencrom using his estate dangerously longer for a modest fee and joins a voyage to the Scilly Isles, as expert mine veteran Mark Daniel left French jail alive, but his information only suggests there is no other rich vain. Dwight agrees to start a new life far away with Caroline, who is convinced sugar uncle Ray Penvenen will undo her disinheriting after a 'decent period'. On the agreed night, Dwight discovers the mole, knocks him down, is just in time on the cliffs to warn the arriving smugglers before customs captain Henshawe can arrest them, and is knocked down himself, so unaware Caroline leaves alone. Ross hides the contraband and himself at home while Demelza desperately plays innocent to the troopers, who find no proof.
