Confidence is a novel by Henry James, first published as a serial in Scribner's Monthly in 1879 and then as a book later the same year. This light and somewhat awkward comedy centers on artist Bernie Longueville, scientist Gordy Wright, and the sometimes inscrutable heroine, Angie Vivian. The plot rambles through various romantic entanglements before reaching an uncomplicated, but still believable happy ending.
Henry James, OM (15 April 1843 – 28 February 1916) was an American writer who spent most of his writing career in Britain. He is regarded as one of the key figures of 19th-century literary realism. 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 a number of novels showing Americans encountering Europe and Europeans. His method of writing from a character's point of view allowed him to explore issues related to consciousness and perception, and his style in later works has been compared to impressionist painting. His imaginative use of point of view, interior monologue and unreliable narrators brought a new depth to narrative fiction.

James contributed significantly to literary criticism, particularly in his insistence that writers be allowed the greatest possible freedom in presenting their view of the world. James claimed that a text must first and foremost be realistic and contain a representation of life that is recognizable to its readers. Good novels, to James, show life in action and are, most importantly, interesting.
In addition to his voluminous works of fiction he published articles and books of travel, biography, autobiography, and criticism, and wrote plays. James alternated between America and Europe for the first twenty years of his life; eventually he settled in England, becoming a British subject in 1915, one year before his death. James was nominated for the Nobel Prize in Literature in 1911, 1912, and 1916.
