The New York Times Magazine had an interesting story yesterday about Norman Mailer's sixth (and last) wife, Norris Church Mailer:
But one of the oldest stories out there is that beauty is no guarantee of a husband’s fidelity. Norris says that in their first eight years together, she believes he remained faithful — more or less. By the time (their son) John Buffalo was 14, she discovered that Mailer had been cheating on her with “a small army of women.”
"After I found out, I kept saying to him, ‘Why didn’t I know?’ And he said, ‘It’s not hard to fool somebody who loves you and trusts you,’ ” she said.
