After he finished reading an earlier biography of himself, Norman Mailer told me, with a mixture of rue and triumph, “He missed the twinkle.” His new biographer, J. Michael Lennon, does not miss the twinkle or much else about the writer who swaggered across a half century of American life, writing novels, plays, poems, essays, journalism, even some theological speculation along with directing movies. Near the end Mailer stood, propped on two canes like a wounded mercenary who had fought behind the lines all his life, a writer/celebrity as drained by the daring and scope of his ambition to find the Northwest Passage to the origins of American mores as Theodore Roosevelt was when, scarred and fevered, he emerged from his post-presidential search for the source of the Amazon.
