Mr. Marx's Secret

Edward Phillips Oppenheim (1866-1946), the self-styled "Prince of Storytellers," wrote thrillers and other popular genres. He invented the "rogue male" school of spy fiction and became an international best-seller for half a century.
"Mr. Oppenheim is a past master of the art of constructing ingenious plots and weaving them around attractive characters."--London Morning Post
