The Devil's Advocate

Percy Greg (1836–1889), son of William Rathbone Greg, was an English writer.

Percy Greg, like his father, wrote about politics, but his views were violently reactionary: his History of the United States to the Reconstruction of the Union (1887) can be said to be more of a polemic, rather than a history.

His Across The Zodiac (1880) is an early science fiction novel. It is said to be the progenitor of the sword-and-planet genre.
