Henry James (1843 - 1916) was an American 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 is best known for a number of novels dealing with the social and marital interplay between émigré Americans, English people, and continental Europeans. Examples of such novels include The Portrait of a Lady, The Ambassadors, and The Wings of the Dove. His later works were increasingly experimental. In describing the internal states of mind and social dynamics of his characters, James often made use of a style in which ambiguous or contradictory motives and impressions were overlaid or juxtaposed in the discussion of a character's psyche. 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 also wrote a number of other highly regarded ghost stories, and is considered one of the greatest masters of the field.
