David Heymann's biography of Robert Kennedy is called RFK. Hardly an original name but it is an original book. Kennedy is an American hero both for his partnership with his brother between 1961 and 1963 and his own bid for the residency, which ended so tragically. Heymann is a superb biography writer who produced the epic A Woman Named Jackie some years ago. He is more at home with Robert Kennedy and you can rely on him for a balanced account. But who knows the accuracy of all the stuff that is banded about the Kennedy brothers' sexual appetite? Heymann recounts it all and the most devastating accusation is that he enjoyed an affair with John Kennedy's widow and his sister-in-law, Jackie Kennedy. As a biographer of both of them, Heymann should know but it is interesting that none of these accusations were made until Jackie Kennedy was dead. Robert Kennedy, a man who fathered 11 children, is accused in the book of having affairs with Marilyn Monroe, Candice Bergen, Kim Novak and Jayne Mansfield. In fact, almost all of the blonde Hollywood stars of the time. And this is where the story becomes suspect. The book contains a disturbing photo I have not seen before of Bobby just after he was shot and is still conscious with his head being cradled by his wife. Notwithstanding that, this book is the best Bobby Kennedy biography so far with equally compelling reasons why it is a perfect present to give or receive.
