Welcome to Hollywood. Take a walk down "The Boulevard of Broken Dreams," where starlets, sex goddesses, matinee idols, American aristocracy, and Mafia moguls meet. It's a town made manic in its heyday by "joy powder" and cocaine-crazed comedies, seduced by vamping heroin heroines, shaken by Fatty Arbuckle's orgiastic excesses and Errol Flynn's amoral extravagances, stunned by Marilyn Monroe's tragic suicide and Sharon Tate's brutal murder.

Here, as never revealed before, is the scalding reality behind the glittering façade: the true stories and darkest secrets behind the lurid headlines that have titillated the world and electrified the nation for decades.
