"It is an easy task," Selingman declared. "This young man is your slave. Whatever your daily business may be here, some part of your time, I imagine, will be spent in his company. Let me know what manner of man he is. Is this innate corruptness which brings him so easily to the bait, or is it the stinging smart of injustice from which he may well be suffering? Or, failing these, has he dared to set his wits against mine, to play the double traitor? If even a suspicion of this should come to you, there must be an end of Mr. Francis Norgate."

Edward Phillips Oppenheim was an English novelist, primarily known for his suspense fiction. He was born on 22 October 1866 in Leicester, the son of a leather merchant, and after attending Wyggeston Grammar School he worked in his father's business for almost 20 years, beginning there at a young age. He continued working in the business, even though he was a successful novelist, until he was 40 at which point he sold the business. He wrote his first book 'Expiation' in 1887 and in 1898 he published 'The Mysterious Mr Sabin', which he described as "The first of my long series of stories dealing with that shadowy and mysterious world of diplomacy." Thereafter he became a prolific writer and by 1900 he had had 14 novels published. While on a business trip to the United States in 1890 he met and married Elise Clara Hopkins of Boston and, on return to England, they lived in Evington, Leicestershire until the First World War,and had one daughter. His wife remained faithful to him throughout his life despite his frequent and highly publicised affairs, which often took place abroad and aboard his luxury yacht.
