On this Grand Tour, Paul continues his journey down the mighty River Tay, from the white-water rapids of Grandtully through the fair city of Perth to the briny firth. Beneath an ancient oak near Dunkeld, Paul meets a man who plays the music of Niel Gow on a fiddle once owned by the composer himself. At a riverside villa, Paul learns about author Beatrix Potter and the inspiration behind the characters of Peter Rabbit and Mrs Tiggy-winkle. Continuing downstream he hears tell of a monster salmon and gets excitingly close to a nest of Osprey chicks. In the fair city of Perth Paul listens to the authentic poetic voice of William Soutar, before meeting some rare moustachioed avians. Journey's end is high above the widening river beside a folly that resembles a castle on the River Rhine.
