The Heir of Redclyffe [EPUB ebook] 

The Heir of Redclyffe tells the story of the Byronic Guy Morville, heir to the Redclyffe baronetcy, and his cousin Philip Morville, a conceited hypocrite who enjoys an unwarrantedly high reputation. When Guy raises money to secretly pay off the debts of his blackguard uncle, Philip spreads the rumour that Guy is a reckless gambler. As a result Guy’s proposed marriage to his guardian’s daughter Amy is called off and he is disowned by his guardian. Guy bears the situation with a new-found Christian fortitude until the uncle clears his character, enabling him to marry Amy after all.
