Heymann is an assiduous researcher who has read all the relevant material and interviewed hundreds of eyewitnesses to the 42-year life of Robert Kennedy. As was made clear in Jeff Shesol's masterly study of RFK and LBJ last year - and indeed is obvious from the most casual reading - Bobby Kennedy was not a pleasant individual. Ruthless, arrogant, narcissistic: Bobby self-confessedly put the interests of the Kennedy family above those of the nation. He suffered from a double handicap: like all the Kennedy boys he was overwhelmed by the dark figure of his monstrous father, the loathsome, bullying, fascistic, anti-semitic womaniser "Ambassador" Joe Kennedy, the man who backed Hitler to beat Churchill; and he was in thrall to his elder brother Jack, to whom he gave years of devoted service. When JFK was assassinated, Bobby was bereft: not only had he lost a beloved sibling but he was now on his own, for he could not rely on Teddy to do for him what he had done for Jack.
Heymann gives Bobby credit for his achievements. As US Attorney-General in 1960-64, he probably accomplished more than any other holder of that office, even if his initial appointment was barefaced nepotism. His relentless pursuit of the Mob was one factor in the Mafia decision to "take out" the president; another was JFK's ingratitude at the role played by the Syndicate in helping to secure him the narrowly won presidential victory over Nixon in 1960. And after 1964, Bobby, who began life on the Right as Senator McCarthy's assistant, moved ever leftward, building a radical coalition of blacks, Hispanics and mainstream Democrats that might have taken him to the White House in November 1968.
In the course of his spectacular career, Bobby made scores of enemies as much by his abrasive personality as his ruthlessness, but three were especially significant: LBJ, FBI director J Edgar Hoover, and Jimmy Hoffa of the Teamsters. This argues for his inadequacy as a politician. No sensible operator would have alienated three such powerful figures simultaneously. Bobby effectively destroyed the credibility of Hoover and his G-Men by demonstrating the power of organised crime, whose existence Hoover had always denied; in the early 1960s, Hoover had 600 agents assigned to the "Communist threat" and only six to the Mob. Bobby then succeeded in redoubling Hoover's hatred by his friendship with Martin Luther King, whom the Bureau director detested with an insane loathing, mainly based on King's frequent liaisons with a bevy of white liberal groupies. It has to be conceded that King scarcely emerges from this account with credit. He described one of his white mistresses as "a piece of tail who can go all night long".
Martin Luther King was a fabled womaniser, but his trysts fade into insignificance alongside the priapic antics of the Kennedys. Heymann, whose previous subjects include Liz Taylor and Jackie Kennedy, really hits his stride when he enters Kitty Kelley territory and we finally realise what "a candid biography" truly means. Much of this book deals with the thousand and one nights of JFK, and his brother's attempt to match him. There is further detail on Jack's affairs with Barbara Marx (later Mrs Frank Sinatra), Angie Dickinson, Janet Leigh, Rhonda Fleming and Arlene Dahl, to name only his best-known mistresses. Bobby tried to match his brother with liaisons with Kim Novak, Lee Remick, Candice Bergen, Grace Kelly, Romy Schneider and Mia Farrow. Women both brothers bedded (sometimes concurrently) included Marilyn Monroe (Heymann thinks she was murdered and that RFK was "probably" implicated) and Jayne Mansfield. Jack found time for an affair with Lee Bouvier, his wife's sister, while Bobby capped this with a tempestuous romance with his brother's widow in 1964.
The po-faced may tut-tut over all the lubricious detail in Heymann's biography, but satyriasis is a central aspect of the truth about the Kennedys. If ever there was sex addiction, here it is. According to Heymann, the Kennedys were prepared to play for the other side too, and he instances homosexual contacts between Jack and one Lem Billings and between Bobby and Rudolf Nureyev. One cannot help feeling that if the Kennedy libido had somehow been crosswired with that of Warren Beatty and a handful of other satyrs and a way found to channel their urges into electrical energy, the USA would have had no need to build Three Mile Island. Truman Capote, one of the author's most valuable sources, sums up the Kennedy addiction well: "If it meant getting off, Jack Kennedy would have inserted his dick in a cement mixer."
Surprisingly, in view of his concentration on the Mafia, Heymann does not mention the theory that the real killer of RFK in the kitchen of the Ambassador Hotel, Los Angeles, on 4 June 1968 was not Sirhan Sirhan but the "bodyguard" Thane Eugene Cesar. But this is the only sensational area left uninvestigated. Students of political science who wish to investigate the political career of RFK will have to turn to Shesol and others, but for the private life, more amazing than any novel, Heymann's hugely enjoyable and deeply fascinating chronicle will remain an indispensable source.
