Prof. George Cavendish is a character in The Sinking City.
Prof. George Cavendish is a professor at the University of Oakmont. He is described as the most brilliant professor of the university, obtaining his Ph.D. at only 25 years of age, in the field of biochemistry. Samuel at the Department of Medicine tells Reed that he seemed to have some sort of family trouble, which made him irritable and interrupted his works, which could otherwise be worthy of a Nobel Prize.
During the quest Quid Pro Quo, Reed learns that he was married to Anna, and that they separated when he learned that her child was not his and being claimed by the EOD. He tried to poison the free fish that the organisation was giving away, but flees when heard by Daryl Grimes. He used ricin, which he stole from Prof. Westerbrook's cabinet by using a duplicated key.
If the choice is made to continue his project of poisoning the EOD's fish, he expresses regret and promises to turn himself in once the EOD has lost his influence. His motive was to avoid anyone suffering as he had and to prevent the organisation from further growth.
