Michael Gross, chronicler of America's rich and powerful, goes west to uncover the very secret history of Los Angeles, specifically those wealthiest and most private of enclaves--Beverly Hills, Bel Air, Holmby Hills, and Beverly Park--through their most mind-boggling estates, and the fascinating, fabulous folks who created and populate them. Gross begins with the mob-driven history of the newest mega-mansion district in L.A., Beverly Park. Using the century-long evolution from adobe huts to $100 million mansions as the baseline of the story, he reveals how a few powerful and often ruthless oil and railroad magnates imposed their idyllic vision of the good life on the Los Angeles landscape to create the legendary communities known as the Platinum Triangle. But the stories of these homes are just a window onto the lives of their owners and occupants over the course of the twentieth century.--From publisher description.
