Geoffrey Trease

Robert Geoffrey Trease, FRSL, was a prolific British writer who published 113 books, mainly for children, between 1934 and 1997, starting with Bows Against the Barons and ending with Cloak for a Spy in 1997. His work has been translated into 20 languages. His grandfather was a historian, and was one of the main influences on his work. He is best known for the children's novel Cue for Treason (1940).

Geoffrey Trease's children's historical novels reflect his insistence on historically correct backgrounds, which he meticulously researched. His ground-breaking study Tales Out of School (1949) pioneered the idea that children's literature should be a serious subject for study and debate and he was one of the first authors who deliberately set out to appeal to both boys and girls and to feature strong leading characters of both sexes.

Trease's first novel, Bows Against the Barons marks the start of his prolific career as a historical novelist. It is notable for reinterpreting the Robin Hood legend and revitalizing the conventions of children's historical fiction in 20th-century Britain.This included the use of modern English, rather than linguistic mannerisms, strong male and female characters, often from less privileged levels of society and meticulous attention to detail. An enduring belief in equality and fairness is a theme in many of his books, as are links between the historical settings of his novels and contemporary issues.
