This story is essentially a very English story. A man sets out to post a letter to a long lost friend, but he keeps on walking rather than posting it. He doesn't know why, he just begins a journey. As he walks he starts to remember things he didn't know he had forgotten and tries to make sense of the last twenty years he seems to have lost. We are drawn in to his discoveries and thoughts, his piecing together of his marriage and what has gone wrong between him and his wife Maureen.
I read this in a couple of days and really enjoyed it.
