London, 1749: A city of vice, crime, and misery. Gangs of ruffians rule the streets, unopposed. Brothels proliferate. Child-beggars starve in filthy gutters. Corrupt night-watchmen and thief-takers turn a blind eye to wrong-doing. And dark creatures lurk in back alleys, called from beyond by the desperate with nothing left to lose. But there is a new force on the streets of London, for the author and magistrate Henry Fielding has teamed up with his brother John to form the city`s first police force the Bow Street Runners. Powered by the Renaissance D100 system and mixing authentic history and the cosmic horror of H.P. Lovecraft, players in Dark Streets take on the roles of officers in London`s first, desperately small, police force, investigating the dark secrets behind the sordid crimes of eighteenth century London.
