A man who no longer talks to his wife. His brief encounter with another woman. The beginnings of a possible affair in letters. Letters which might be turned into a novel, or a confession. These are the facts. But the facts begin to shift. Fiction and reality become indistinguishable in one person's search for truth and another's realisation of desire. What I Have Written is a novel of sexual obsession, a literary puzzle in which what is written is far from what it seems.
