The best nugget from Norman Mailer's personal correspondence: Tina Brown, the English editor of Vanity Fair and the New Yorker, asked him to provide a reference for her green card bid. (It couldn't have hurt to have an endorsement from America's best writer, or someone who considered himself that.) For someone with such a reputation for pugilism, Mailer's letters are masterpieces of flattery. The writer, who died last year, produced the requisitely over-the-top letter to include in Tina Brown's immigration application, and appended an even more cloying cover note: "Don't believe a word of this. You are too attractive ever to let your head swell."
