Book excerpt: Who introduced Babe Ruth to Albert Einstein, and why? Who was privy to the pact between Lee Harvey Oswald and James Earl Ray, the romance of the artist formerly known as Prince and Princess Di, and the fate of Marilyn Monroe? Behold Max Vail (b. Maxim Valesky, 1900, St. Petersburg; d. 1999, Manhattan)--a middleman of genius who be-strode the realms of politics, entertainment, art, sport, crime and science. "I have witnessed the world," he said simply. Yet the man who knew everyone--kept their secrets, did their deals and never forgot where the bodies were buried--was himself known to virtually none. His private diaries, here made vivid with eighty-six extraordinary computer collages, provide nothing less than the secret history of our century, confirming some long-rumored events and revealing others that are freshly shocking. In all, some two hundred iconic personalities throng these pages, and their sagas--comic, ignominious, tragic, heroic and bizarre--make a strange, compelling narrative from the conflicted desires and obsessions of our times, and a rare gift to the millennium.
