In historical sequence, though not in order of being written, this is the most recent of Peter Hopkirk's Great Game books. It contains the usual cast of colourful characters undertaking daring high jinks, only this time Britain's opponents are Lenin and Stalin instead of the Tsar and Kaiser Wilhelm, and the action is spread over a wider geographical canvas. Partly as a consequence, this book feels more episodic that the prequels, but what episodes! Whether it's Enver Pasha carving his wife's name in a tree before leading a suicidal cavalry charge against Soviet machine guns, M N Roy "liberating" the Emir of Bokhara's harem, Fanny Borodin being spirited away from under the noses of the Chinese authorities or Baron Ungern-Sternberg's psychotic rampage across Mongolia, I think it's safe to predict you won't be bored.
As in his other books, Hopkirk makes extensive use of first-hand accounts written by the people involved in these events. This is both a strength - it makes you feel like you're in the thick of the action - and a weakness, since the original writers are at times a tad economical with the truth. Thus, Bailey gives no hint of what he was really up to during his months in hiding in Tashkent, whilst Alioshin's tales of serving under Ungern-Sternberg verge on the fictional. Hopkirk is aware of this and provides health warnings where appropriate.
I love these books. At school, teachers tried very hard to convince me history was dull; in Peter Hopkirk's hands, it's anything but that.
