As the blurb says, "deliciously corrupt" and wonderfully amoral. Harry Flashman, a young officer in the British Army in Afghanistan, 1840, is charming, unconscionably lucky, and a thoroughgoing cad, bounder, scoundrel, and coward. (Why do "bounder, scoundrel and coward" all almost rhyme? Does that say something about our perception of phonemes?) No more or less plausible than most adventure fiction, and as far as I can tell, true to history. Enjoy!
