The Demolished Man

The Demolished Man is a science fiction novel by American writer Alfred Bester, which was the first Hugo Award winner in 1953. An example of inverted detective story, it was first serialized in three parts, beginning with the January 1952 issue of Galaxy Science Fiction, followed by publication of the novel in 1953. The novel is dedicated to Galaxy's editor, H. L. Gold, who made suggestions during its writing. Bester's title was Demolition!, but Gold talked him out of it.
