Who had prevented her attending the Conservatoire to develop her talent as a pianist. Her conviction that she must soon be released is shattered when the witnesses who might establish her innocence disappear or die. As if her treatment by the other women were not enough, a group of terrorists break into Wentworth shortly after her arrival, and Jenny is tormented by their leader, Ram, who holds an unloaded gun to her forehead and pulls the trigger. Her lawyer is pretty hopeless, and she appoints another suggested by May Collins. Her trial ends with a hung jury and she is returned to Wentworth to await a retrial. She finds out that her uncle Steve Formby has been arrested for his wife's, Harriet Formby, murder. He has also confessed to her grandmother's murder.
