Country dialect this is pronounced Jan) Ridd is the son of a respectable farmer who was murdered in cold blood by a member of the notorious Doone clan, a once-noble family now living in the isolated Doone Valley. Battling his desire for revenge, John also grows into a respectable farmer and continues to take good care of his mother and two sisters. He falls hopelessly in love with Lorna, a girl he meets quite by accident, who turns out to be not only the granddaughter of Sir Ensor Doone (lord of the Doones), but destined to marry (against her will) the impetuous, menacing, and now jealous heir of the Doone Valley, Carver Doone. Carver will let nothing get in the way of his marriage to Lorna, which he plans to force upon her once Sir Ensor dies and he comes into his inheritance”.
