Just finished "The Man Who Would Be King; the first American in Afghanistan" (ISBN 0-374-20178-1) by Ben Macintyre. The story is a good read, about Josiah Harlan who went to Afghanistan in 1828; supposedly it was the inspiration for Kipling's story. Interesting accounts of inter-tribal combat/feuds and the political infighting.
Parts of the book remind me of the movie based on Kipling's book, the one with Sean Connery and Michael Caine from the '70s.
