The Carnmore smelting company is a success and Ross makes more of an enemy of George by outbidding him for copper at auction. Meanwhile, Francis is increasingly volatile now that he has lost his mine and is reduced to working the land, so Verity avoids speaking to him about her plans to marry Captain Blamey. When Ross and Zacky discover there is fever at Bodmin Jail just weeks before Jim is to be released, Ross asks Dwight to accompany him to the prison. Ross forces his way into the jail and discovers that Jim is near death. They break Jim out from the jail in a desperate attempt to save him. Returning home, Ross is expected to attend George’s grand ball. He is sickened at the thought of going amongst the people responsible for Jim’s incarceration, but Verity persuades him that he must do it for Demelza and Julia’s sake; to remind everyone that he is one of their class so they won’t arrest him for the prison break. However, at the ball Ross is fighting drunk and Demelza is aghast that she has been left to fend for herself at her first ever high society social event.
