The Gangs of Novigrad

Quest Description
"When Geralt entered the Novigrad bathhouse, he happened to walk in on a meeting of the hads of the city's criminal underworld. Becoming an unwitting participant in their conversation, he learned of hte conflict between the triumbirate made up of the King of Beggars, Sigi Reuven, and Carl "Cleaver" Varese on the one had, and Whoreson Junior and the unknown powers backing him on the other. Cleaver in particular wanted Whoreson gone and offered Geralt help in finding and gettin to the bastard, which suited Geralt's interests. They say hands aplenty make for light work, and Geralt had every reason to believe this applied to gang warfare as much as it did to cleaning a barn, so he graciously accepted the gangster's offer."
