A fence and information broker operating out of Nighttown, the Sprawl's underworld district. The Finn appears across multiple Gibson works - Neuromancer, the short stories, and the Count Zero era. He deals in hardware, information, and anything else with value, operating through a network of contacts that extends from street level to corporate espionage. He is one of Case's few reliable contacts - not trustworthy in the conventional sense, but consistent in his unreliability, which amounts to the same thing. Wintermute uses his face and voice as one of its preferred communication personas.
