King Charles II dies, and the Duke of Monmouth (the late king's illegitimate son) challenges Charles's brother James for the throne. The Doones, abandoning their plan to marry Lorna to Carver and claim her wealth, side with Monmouth in the hope of reclaiming their ancestral lands. However, Monmouth is defeated at the Battle of Sedgemoor, and his associates are sought for treason. John Ridd is captured during the revolution. Innocent of all charges, he is taken to London by an old friend to clear his name. There, he is reunited with Lorna (now Lorna Dugal), whose love for him has not diminished. When he thwarts an attack on Lorna's great-uncle and legal guardian Earl Brandir, John is granted a pardon, a title, and a coat of arms by the king and returns a free man to Exmoor.
