From Wikipedia: Henry James (15 April 1843 – 28 February 1916) was an American-British author. He is regarded as a key transitional figure between literary realism and literary modernism, and is considered by many to be among the greatest novelists in the English language. He was the son of Henry James Sr. and the brother of philosopher and psychologist William James and diarist Alice James.
He is best known for his novels dealing with the social and marital interplay between émigré Americans, the English, and continental Europeans, such as The Portrait of a Lady. His later works, such as The Ambassadors, The Wings of the Dove and The Golden Bowl were increasingly experimental. In describing the internal states of mind and social dynamics of his characters, James often wrote in a style in which ambiguous or contradictory motives and impressions were overlaid or juxtaposed in the discussion of a character's psyche. For their unique ambiguity, as well as for other aspects of their composition, his late works have been compared to impressionist painting.
His novella The Turn of the Screw has garnered a reputation as the most analysed and ambiguous ghost story in the English language and remains his most widely adapted work in other media. He wrote other highly regarded ghost stories, such as "The Jolly Corner".
