Michael Portillo's exploration of the West Country continues in south Devon. Guided by his 1930s Bradshaw's, Michael arrives in Paignton to investigate an extraordinarily high murder rate in the literature of the 1930s! The Dartmouth Steam Railway conveys him in style to the beautiful home of Agatha Christie, in the company of her great-grandson, James Prichard.At Dawlish, Michael discovers violets were so prized between the wars they had their own train to London and that the flower trade continues to flourish at Whetman Pinks, established in the same year as Michael's Bradshaw's.Exeter Station takes centre stage as Michael hears from the granddaughter of publisher Allen Lane how he was inspired to invent the Penguin paperback.Striking north to Tiverton, in the pretty Culm Valley, Michael traces the origins of a national institution, the Young Farmers' Clubs, and sees how the organisation has evolved.
