Book excerpt: Twin towns with a fascinating history, they constitute the Sussex resort that, to mark the Millennium, the Queen declared to be a City. A giant step from the Neolithic camp built on Whitehawk Hill in the fourth millennium B.C. The author, who since 1950 has worked as a planner in Brighton, has now produced the first integrated history of the two towns. His sense of humour is evident on every page of an entertaining and richly illustrated narrative, through prehistoric downsmen to the trippers and the technocrats of today's proud City.
