[close] Travel is no longer a luxury and not always an entertainment. Many journeys need to be made‹to get home or away from an enemy, to work, to find a last resting place, or because someone has told you to go. This issue of Granta is about such journeys; you might call it necessary travel writing, with Decca Aitkenhead: looking for cheap sex and drugs; Manuel Bauer: a child¹s escape over the Himalayas; Isabel Hilton: what have they done to Beijing?; Ian Jack: the train crash that stopped Britain; Ryszrd Kapuscinski: in the forests of Cameroon; Ian McEwan: on the retreat to Dunkirk, 1940; John Ryle: the last Emperor makes his last journey; Dayanita Singh: inside a sanctuary for girls in Benares; Simon Winchester: how Britain and the US made a people homeless; plus the untold story of how the FBI pursued James Baldwin at home, revealed by James Campbell. Granta is the paperback magazine of new writing. Every issue features the best new fiction, reportage, memoir and photography, generally collected under a theme.
