Crime writer Alexander McCall Smith investigates one of the greatest literary frauds in history. When James Macpherson uncovered heroic Scottish poems dating back more than a thousand years, they caused a sensation. But they sparked a 20-year war with the literary giant Dr Johnson, and left Macpherson with a reputation as a calculating swindler. McCall Smith travels through the Highlands to uncover the true story of the poems of Ossian, and how they changed the course of European art forever.
