The White People - the story was written in the late 1890s as part of Machen's struggle to find a direction for a projected novel, other outgrowths of which were published as the novella A Fragment of Life (collected in The House of Souls) and as the collection of prose poems Ornaments in Jade (1924).

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 where she lives and conversations with her nurse, who initiates her into a secret world of folklore and black magic.
