Unlikely pilgrimage of Harold Fry. Rachel Joyce. 2014.

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.
