Elizabeth approves but Francis is outraged, wrongly suspecting Ross's involvement and is thus susceptible to siding with George Warleggan, who has cancelled Francis's debt to the bank. Other bank customers are less fortunate - especially those in Ross's collective, who are blackmailed by the Warleggans into withdrawing their capital, ensuring the cooperative's demise. Mark Daniel, aware of Keren's infidelity, kills her in a fit of rage. Ross helps him escape arrest but before he goes Mark tells Ross that, whilst hiding in the disused mine Wheal Grace, he has found copper.
