All human desire is laid bare in Filthy London, a pocket-size guide through London’s ancient streets, from leafy suburbs to the throbbing heart of the city.

There are medieval bawdy houses and Georgian flogging machines, toe-sucking, striptease, nude saunas and dogging, with cameos from a cast that includes King George IV, King of Soho Paul Raymond, John Profumo and Aleister Crowley, the Wickedest Man In The World.

London is filled with dirty secrets, 40 of which we’re delighted to spill in this new guide.
