Throughout all my writing years I have been aware of one intention only, I suppose, and that is to try to recapture for myself certain moments, incidents, events that have at the time acted as some kind of emotional impetus. Writing about them seemed to give a permanence. Others might read what I had seen or felt and be affected too. This is what I hoped. But primarily writing is a form of self-indulgence. I admit readily that as I wrote, the shape or outline of the captive moment changed. There's the pity! Never was I able to recapture in its first innocence that primary stimulus. The very nature of fiction writing affected whatever I touched. Other characters intruded. Dialogue sharpened or blunted what had appeared to me as entire in itself.
