It must be 16 years since I spotted this in a book club catalogue and, out of idle curiosity, ordered it. Little did I realise that it would ensnare me in a fascination for this part of the world (Central Asia) and this period of history (early twentieth century) which has yet to show any signs of dissipating. This is due in part to Hopkirk's skill as a storyteller, in part to the astonishment of learning there was so much more to World War One than the mechanised butchery of the Western Front - and, if you thought really hard, Peter O'Toole prancing around in shiny white robes.
As mentioned by other reviewers, what we have here is the story of German attempts to stir up a Holy War against Britain amongst the Moslem population of Persia, Afghanistan and India. The principal dramatis personae are German and British secret agents and Indian revolutionaries, and their adventures are often related in their own words. It is Hopkirk's ability to frame these in the political and military context of the times that makes this book so engrossing.
The collapse of the Russian armed forces after the revolution of 1917, at a time when the Allies had all but won this clandestine war, drastically changed the game plan. The British now found themselves providing limited military support and large amounts of cash to anyone prepared to resist the eastwards march of Turkish and German armies - i.e. anyone other than the Bolsheviks. The intervention here, as elsewhere in the Russian Civil War, ultimately benefitted nobody and only prolonged the suffering of the local people.
It is rather poignant to reread this book at a time when the West is once again getting its collective knickers in a twist at the thought of militant Islam. The lessons of history, it seems, remain stubbornly unlearned. On a less maudlin note, when can we expect the next instalment in your Great Game series, Mr Hopkirk - the one covering the 1940s onwards?
