Holmes travels to Africa to help Tarzan stop a German spy's nefarious weapon in this "glorious" sci-fi pastiche by the Hugo Award–winning author ( Locus ). When the acclaimed science fiction author Philip José Farmer took up the mantle of Sherlock Holmes, he produced an adventure unlike anything fans of the Baker Street detective had seen before. In this far-flung mystery of World War I, Holmes and Watson are sent to Egypt to stop the German spy Von Bork from perfecting a weapon that could destroy all of Great Britain. Along the way, the sleuthing team form an alliance with the famous Lord Greystoke—peer of the Realm and lord of the jungle!
