Frank travels to claim the property. He meets with Justice Inglewood to review his uncle's will and learns from him that Diana and her father are thought to be out of England now; she is single and her father was deeply involved with the Rebellion, and he had visited Die in the role of Father Vaughan. This was the secret that Rashleigh held over her. With Andrew Fairservice, Frank takes possession of Osbaldistone Hall. Nostalgically selecting the library to sleep in, he finds Diana and her father hiding there. They request sanctuary as they are being hunted due to the failure of the Jacobite uprising. They tell Frank how Sir Frederick had been hidden at the Hall during his earlier stay. They plan to leave, but Rashleigh arrives with Jobson and the local constables, bringing a warrant to take possession of the Hall and arrest the Vernons and Frank. They are easily captured and taken away in a carriage. Still on the property, Rob Roy springs an ambush, freeing them all and killing Rashleigh. Rob Roy and his men bring Diana and her father to safety in France. Not many months later, after Frank begins working with his father, they learn that Diana's father is dying in France, and allows his daughter to make her own choice of the convent or marriage. Frank tells his father of his love for Diana. He gains his father's approval to marry a Catholic, as startling to him as his son owning Osbaldistone Hall.
