I spent most of the '60s, when I was starting to try to write novels, living and working in Greece and Turkey. These are countries where the ancient past is interfused with the daily present, and I remember being struck with wonder at the constant sense of continuity and connection, the reminders that lie in wait for you at every turn.
As I wrote I began to see more strongly that there were inescapable analogies. You couldn't really live through the '80s without feeling how crass and distasteful some of the economic doctrines were. The slave trade is a perfect model for that kind of total devotion to the profit motive without reckoning the human consequences.
