Fields of Sleep

From the front flap of the Donald Grant edition: "A magnificent fantasy novel of lost lands in which Victor Marshall is hired to find an Englishman who has disappeared into remote and unexplored Asia. Marshall's expedition leads him to a hidden valley whose inhabitants are descended from ancient Chaldean colonists. They are dependent upon a narcotic flower whose fragrance produces a strange ecstasy, while destroying the power of speech. Written and first published in 1923, Fields of Sleep is a strangely imaginative novel that combines great beauty with an even deeper sense of horror."
