Complete and unabridged, with 36 full-page plates by Eugène Fromentin, Eugène Delacroix and Edvard Munch. An Englishman in the Sahara buys a slave girl out of a caravan and inherits her enemies along with her secret. Le Queux traveled in North Africa and the desert geography is sound even where the plot is not. This edition is bound with a gallery of 36 plates after Munch, Fromentin, Delacroix and Walton, and includes 23 illustrations restored and coloured for it.

William Le Queux (1864-1927) was an Anglo-French journalist and novelist born in London. He was a foreign correspondent, an early wireless experimenter, and a tireless self-publicist who insisted he had served as a secret agent. His works include Zoraida, The Great War in England in 1897, The Eye of Istar, and The Pauper of Park Lane.
