Sir Hugh Seymour Walpole, CBE (13 March 1884 – 1 June 1941) was a New Zealand–born English novelist. He was the son of an Anglican clergyman, intended for a career in the church but drawn instead to writing. Among those who encouraged him were the authors Henry James and Arnold Bennett. His skill at scene-setting, vivid plots, and high profile as a lecturer brought him a large readership in the United Kingdom and North America. He was a best-selling author in the 1920s and 1930s, but has been largely neglected since his death.
After his first novel, The Wooden Horse, in 1909, Walpole wrote prolifically, producing at least one book every year. He was a spontaneous story-teller, writing quickly to get all his ideas on paper, seldom revising. His first novel to achieve real success was his third, Mr Perrin and Mr Traill, a tragicomic story of a fatal clash between two schoolmasters. Walpole's output was large and varied. Between 1909 and 1941 he wrote thirty-six novels, five volumes of short stories, two original plays and three volumes of memoirs. His range included disturbing studies of the macabre, children's stories and historical fiction, most notably his "Herries Chronicle" series, set in the Lake District.
