"I use the furniture of espionage to amuse the reader, to make the reader listen to me, because most people like to read about intrigue and spies. I hope to provide a metaphor for the average reader's daily life. Most of us live in a slightly conspiratorial relationship with our employer and perhaps with our marriage. I think what gives my works whatever universality they have is that they use the metaphysical secret world to describe some realities of the overt world."
