King of the Khyber Rifles may well be Mundy's most famous work. Set in India and the regions beyond, it was successful enough so that two movies were adapted from its pages, although neither portrayed Athelstan King as Mundy intended him. And neither evoked the fantasy and mysticism that are so much a part of this book. Somewhere beyond India, on a quest for the remote and half-fabled Khinjan Caves, King meets a cast of characters that includes the Princess Yasmini, Ismail, Darya Khan, and various hakims, rangars, and mullahs. And deep in the unknown caverns lie "the sleepers", about whom a marvelous and fantastic tale is spun.
