Richard M. Helms, the first director of Central Intelligence to rise from the ranks, was fond of saying that the CIA had been founded to make sure that there would never be another Pearl Harbor. Underlying this mission impossible was the wishful supposition that an America that knew everything could prevent anything.

As an old man who remembers the intellectual exhilaration and the pleasure of having done good work that characterized the CIA when it was young, I wonder if it might not be better to speak and think in terms of restoring its culture.

Anything that's secret, clandestine, loaded with such a supercargo of speculation, misinformation, disinformation and, for that matter, accurate revelations, creates an appetite.

I have to tell you, I'm a happy man. I've lived the life I wanted to live. I've written the books I wanted to write. No publisher has ever even suggested that I change so much as a phrase - commas and periods, yes - and I suspect that I have a lot of serious readers; in fact, I know.

I've consciously tried not to romanticize anything, especially not intelligence work. I've always said that I've been writing a series of episodic, naturalistic novels. The people just happen to be spies, politicians, civil servants.
