Henry Dorsett Case is a main character from William Gibson's Neuromancer. He is a console cowboy, who was making a living using cyberspace to carry out lucrative crime until he defrauded a client. In retaliation, the client infected Case with a mycotoxin that destroyed his ability to interface with the grid. Deprived of his talent, Case is forced to make a living as a middle hand trading in illicit substances and technology in Chiba. His drug use makes him paranoid, and his desperation grows as his deals start falling through and his addicted girlfriend Linda Lee steals the last assets he had left.
