E. Phillips Oppenheim — who invented the international-intrigue novel and produced some hundred and fifteen of them — spins an elegant Edwardian thriller of diplomacy and death. A Japanese prince, the most charming man in London, stands at the center of an affair in which two men die and an alliance between empires hangs in the balance, while Inspector Jacks knows exactly who is responsible and can prove nothing. Unusually for its day, the prince is the most honorable person in the book. This edition presents the complete and unabridged novel, newly typeset and illustrated with 48 full-page color plates.
