Considered by some to be Oppenheim's greatest spy story. Leaving England under suspicion as a murderer, Sir Everard Dominey turns up in German East Africa after ten years of wandering and is rescued from death in the jungle by the German Commandant, Baron von Ragastein, a former fellow-student at Oxford. What follows is a story of impersonation, romance, and a revelation of the German espionage system that is filled with suspense - and a mystery that the reader won't solve until the end of the story.
