It's a story about painters, in the Elizabethan Renaissance. Often they're not even interested in the painter's techniques. Like collectors, their interest seemed more focused on the provenance of a work. I know a great many painters. Painters are far more driven than writers, or they wouldn't be able to do it at all.
Painters are very private people who work inside their heads, like fiction writers.
A number of them are unpleasant and antisocial. When I've interviewed painters for this book, they always asked if I was going to say what I think drives them. That's the story I hope to tell in my next book. A Calculated Risk was my earth book, dealing with finances and banking, the material world. The Eight , was my air or spirit book.
