Who was Arminius Vambery? A poverty-stricken, Jewish autodidact; a linguist, traveller, and writer; or a sometime Zionist, inspiration for Draculas nemesis, and British secret agent?

Vambery wrote his own story many times over. And it was these often highly embroidered accounts of journeys through Persia and Central Asia that saw him acclaimed in Victorian England as an intrepid explorer and daring adventurer. Against the backdrop of the Great Game, in which Russia and Britain jostled for territory, influence, and control of the borders and gateways to Central Asia and its wealth, Vambery played the roles of hero and double-dealer, of fascinated witness and imperial charlatan.

The Dervish Bowl is the story of these competing narratives, a compelling investigation of the ever-changing persona Vambery created for himself, and of the man who emerges from his private correspondence and the accounts of both his friends and his enemies, many of whom were themselves major players in the geopolitical adventures of the volatile nineteenth century a time when Britains ambitions for her empire were at their height, yet nothing and no one was quite as they seemed.
