Book excerpt: Sybille Bedford once wrote that travel writing is inseparable from the writer's tastes, idiosyncrasies, and general temperament - it is what happens to him when he is confronted with a column, a bird, a sage, a cheat, a riot; wine, fruit, dirt; the delay in the dirt, the failing airplane. 'Pleasures and Landscapes' is what happened to Mrs Bedford when, at the peak of her literary powers, she traveled through France, Italy, and the rest of Europe for Vogue, Esquire, and other magazines - eight classic essays that secure her a place at the table with A.J. Liebling and M.F.K. Fisher.
