The Old English Baron is an ambitious rewriting of Horace Walpole's Castle of Otranto, transporting the trappings of the Gothic to medieval England. The noble hero endures many adventures of romantic horror in order to obtain his rightful heritage, and the story concludes with a dramatic day of retribution. Reeve's book is increasingly recognized as a major influence in the development of Gothic fiction. When Sir Philip Harclay returns to England after a long absence, he finds that his childhood friend, Arthur, Lord Lovel, is no longer alive, and that the castle and estates of the Lovel family have twice changed hands. But a mysteriously abandoned set of rooms in the castle promises to disclose the secrets of the past. After a series of frantic episodes and surprising revelations, culminating in a trial by combat, the crimes of the usurper and the legitimacy of the true heir are finally discovered.
