I've read about a third of the way through a book that chronicles the dismantling of the Ottoman Empire by UK/France/Russia, and involves the colonial land grab of the Middle East and Central Asia. It's called A Peace to End All Peace, it's by David Fromkin.
Have you read any of Peter Hopkirk’s books. The Great Game, Secret Service East of Constantinople etc. Haven’t read them all yet but an interesting and relatively unknown period of history full of larger than life characters on both sides. Look up a guy called Reginald Teague-Jones.
