...my publisher asked me, and I know there is no answer. Writing isn't about answers, not even crime fiction writing. It is about moving. All human activity is about moving, about getting somewhere, physically or mentally, intellectually or emotionally. Some take to sport, others to science or business. I take to writing.
To get somewhere.
I am not so much intrigued by human relations or human tragedy, as I am by the impact of human actions on our lives. What I mean is this: you live your life and you change your life by doing things. Once you decide to do something, whatever it is, good or bad, and you actually DO it, things around you start to change. They adjust themselves to your actions. How they change, is difficult to predict, but they will change. Some people will move away from you; others, sometimes people you don't even know, will move towards you.
Sometimes that is the way I view my writing, and sometimes I write just to find out what will happen. Not in the story, but in my life.
