The White People- Arthur Machen
A discussion between two men on the nature of evil leads one of them to reveal a mysterious Green Book he possesses. It is a young girl's diary, in which she describes in ingenuous, evocative prose her strange impressions of the countryside in which she lives as well as conversations with her nurse, who initiates her into a secret world of folklore and ritual magic. Arthur Machen (1863-1947) was a Welsh author and mystic of the 1890s and early 20th century. He is best known for his influential supernatural, fantasy, and horror fiction.
