This is the second novel dealing with Old Ugly Face s effort to protect Tibetan religious traditions from Russian, Japanese, and Chinese intrigue just prior to World War II, a sequel to the novel The Thunder Dragon Gate. It also continues the story of Elsa Burbage and her husband Tom Grayne, whom she left behind in a Tibe-tan cave to return to Darjeeling to have their child. The child was born, however, at 17,000 feet in the Himalayas during a blizzard, yet made it through that ordeal only to die after arriving safely in India. Elsa wishes to return to Tom, and persuades the American adventurer Andrew Gunning the man who brought her out of Tibet to let her join him in his clandestine journey back to Tom. This fast-paced adventure novel by Talbot Mundy is one of the greatest novels ever written of the rigors and tests of the spiritual path. It is Mundy at his best.
