Gentle slopes, rough coasts and broad horizons, salty marshes and lavender, sugar beet and rose gardens - this is East Anglia, a landscape of huge open skies which has been a temptation to every invader and every get-rich-quick merchant in history; and with Constable, Gainsborough and many others, it has been home to some of the most quintessentially English painting and building. Peter Sager, takes us all over Norfolk, Suffolk and Essex, from prehistoric flint mines to Hi-Tech architecture, from the philosophy of John Locke to the detective stories of Dorothy L. Sayers, from the music of Benjamin Britten to the races at Newmarket.
