Longlisted for the Man Booker Prize 2012: 'The odyssey of a simple man, original, subtle and touching' -Claire Tomalin When Harold Fry leaves home one morning to post a letter, with his wife hoovering upstairs, he has no idea that he is about to walk from one end of the country to the other. He has no hiking boots or map, let alone a compass, waterproof or mobile phone. All he knows is that he must keep walking. To save someone else's life. 'Wonderful' -Guardian
