At the start of the twentieth century, British intelligence agents began to venture in increasing numbers to the Arab lands of the Ottoman Empire, drawn by the twin objectives of securing the route to India and finding adventure and spiritualism in an antique land. But these competing objectives created a dilemma: how were they to discreetly and patriotically gather facts in a region they were drawn to for its legendary inscrutability and promise of fame and escape from Britain? Spies in Arabia tracks the intelligence community's tactical grappling with this dilemma and its myriad cultural, institutional, and political consequences during and after the Great War. Arguing that violence and culture were more closely allied in imperial rule than has been recognized, it tells the story of an imperial state dependent on equivocal agents groping through a fog of cultural notions and an interfering mass democracy towards a new style of "covert empire" centred on a brutal aerial surveillance regime in Iraq.
