My wife says I had a nervous breakdown during the writing of Mefisto. Maybe I did, but what's a nervous breakdown for a writer? For a writer every day is a nervous breakdown. [...] The book came out in the spring, and I remember I spent that following summer digging my garden — Voltaire would have been proud. I made a wonderful garden. Grew beans, lettuces. I was healing myself from some kind of traumatic process that I don't pretend to understand. All right, let's agree with my wife and call it a nervous breakdown.
