I began to design the entire book in my mind while driving, and got increasingly excited, until I heard a police car’s siren telling me to pull over: I was driving far above the speed limit. The Italian policeman asked me politely if I was crazy to drive at that speed. I explained that I had just found the idea I’d been seeking for so long; the policeman let me go without a ticket, and wished me good luck with the book. This is that book.
