'A Rogues' Gallery' is a journey through the past half-century, charting the ups and downs of leading writers and actors, thinkers, entertainers, gurus, politicians and public non-conformists. It collects the snapshots gathered during one journalist's long and varied career of the famous and infamous, foolish and funny, when they were off-camera. Here are private views of the tensions that opened cracks in the marriages of Arthur Miller and Marilyn Monroe, Harold Pinter and Vivien Merchant, Laurence Olivier and Joan Plowright.
