"We had a lengthy discussion of the difficulties I had had working on other biographies and the efforts made by Martha Gellhorn, Susan Sontag and others to prevent publication. Gellhorn's representative, Bill Buford, sent a threatening letter to my publisher. Michael, a journalist first, called Buford a "dirty dog." I never dreamed, then, that he, too, would, in the end, assume a rather high-handed attitude towards my manuscript, ordering me to make changes and deferring to the feelings of others. On this day, I said: "I don't respond well to those threats. I don't allow them to intimidate me." "We don't believe in authorised biographies," Michael concluded. "All authorised biographies are hereby condemned." I would remember these words later when Michael the Apostate appeared."
