**Underworld** n. 1. the part of society comprising those who live by organised crime and immorality. 2. the mythical abode of the dead under the earth.

Take a walk on the dark side of the street in this unique exploration of the fears and desires at the heart of the British Empire, from the Regency dandy's playground to the grim and gothic labyrinths of the Victorian city. Enter a world of gin spinners, sneaksmen and Covent Garden nuns, where bare-knuckled boxers slog it out for dozens of rounds, children are worth more dead than alive, and the Thames holds more bodies than the Ganges. This is the Modern Babylon, a place of brutal poverty, violent crime, strong drink, pornography and prostitution; of low neighbourhoods and crooked houses with windows out like broken teeth, wraithlike urchins with haunted eyes, desperate, ruthless and vicious men, and the broken remnants of once fine girls: a grey, bleak, infernal place, where gaslights fail to pierce the pestilential fog, and coppers travel in pairs, if they venture there at all.
