In this second of Boothby's Dr. Nikola novels, adventurer Wilfred Bruce meets Dr. Nokola, who wants to hire Bruce to help him penetrate a secluded Chinese monastic society to obtain the occult secret for immortality. Dr. Nikola demonstrates to Bruce that he and his black cat have magical powers. He learned of the Chinese society from a disgraced Oxford don who spent many years in China and from an old Buddhist priest. He tells Bruce: "I will confess that the prospect of what I am about to attempt almost frightens me. It is neither more nor less than to penetrate, with the help of certain Chinese secret societies, into the most extraordinary seat of learning that you or any other men ever heard of, and when there to beg, borrow, or steal the marvelous secrets they possess. I cannot go alone, for a hundred reasons, therefore I must find a man to accompany me; that man must be one in a thousand, and he must also necessarily be a consummate Chinese scholar. He must be plucky beyond the average, he must be capable of disguising himself so that his nationality shall never for a moment be suspected, and he must go fully convinced in his own mind that he will never return. If he is prepared to undertake so much I am prepared to be generous." He is convinced that Bruce is the right man for the task. After consideration of the risks and reward, Bruce joins Dr. Nicola on his quest.Guy Newell Boothby was an Australian novelist and writer, born in Adelaide, son of Thomas Wilde Boothby, who for a time was a member of the South Australian Legislative Assembly. Guy Boothby's grandfather was Benjamin Boothby (1803-1868), judge of the supreme court of South Australia from 1853 to 1867. When Boothby was six, he traveled to England with his mother. Around 1890, he took the position of private secretary to the mayor of Adelaide, Australia, but was not content with the work due to little opportunity for advancement. He turned to his writing talents, writing librettos for 2 comic operas and stories about Australian life. Boothby moved back to the United Kingdom in 1894. He wrote over 50 books in the course of a decade, before dying of pneumonia in Bournemouth. Some of Boothby's earlier works were non-fiction, but later he turned to writing novels. He was once well known for his series of five novels about Doctor Nikola, an occultist anti-hero seeking immortality and world domination. In A Prince of Swindlers he created the character of Simon Carne, a gentleman thief in the Raffles mold, with an alter ago as the eccentric detective Klimo: Carne first appeared in Pearson's Magazine in 1897, predating Raffles by two years.
