Fowles refers to Henry James (1843-1916), an American by birth who spent the last 40 years of his life living in England, eventually becoming a British subject.  James was one of the pre-eminent novelists of his age, specialising in the exploration of the psychological depths of his characters, extremely long sentences and ornate, extravagant use of language.
