King of the Khyber Rifles by Talbot Mundy (Jim Grim #3)

KING OF THE KHYBER PASS is the third book in Talbot Mundy's 'Jim Grim' adventures set in India and the Middle East during the British Raj. Athelstan King is a secret agent for the British Raj at the beginning of World War I. Heavily influenced both by Mundy's own unsuccessful career in India and by his interest in theosophy, it describes King's adventures among the Muslim tribes of northern India accompanied by the mystical woman adventurer Yasmini and the Turkish mullah Muhammed Anim.
