George G. Gilman is one pseudonym, or pen name, of Terry Harknett. Under that name Harknett wrote three series of Western books: Edge, which his US publisher would brand, "The Most Violent Westerns In Print"; Adam Steele (this character and Edge appeared together in three books); and The Undertaker. The Gilman books were known for their sardonic and sarcastic humor and for their very violent content. Fans call themselves "Gilmanites" or "Gilmaniacs".
