Serious money

London is a plutocrat's paradise, with more resident billionaires than New York, Hong Kong or Moscow. Far from trickling down, their wealth is burning up the environment and swallowing up the city. But what do we really know about London's super rich, and the lives they lead? To find out more about this secretive, security-heavy elite, sociologist Caroline Knowles walks the streets of London from the City to suburban Surrey, via Kensington, Notting Hill, Mayfair and elsewhere. Her walks reveal how the wealthy shape the capital in their image, creating a new world of gated communities and luxury developments. A move behind closed doors takes us ever further into the dark heart of the plutocratic city, from multimillion-pound mansions to high-end hotels and gentlemen's clubs. Along the way we meet a wide and wickedly entertaining cast of millionaires, billionaires and those who serve them.
