The Sphinx Without A Secret

The Sphinx without a Secret centers around two college friends, who, after not seeing each other in ten years, meet by chance in Paris.  The first is our narrator, who notices that his friend, Gerald Murchison, is much changed and concludes his problem must be a woman.
So, he proceeds to ask his friend about it, who shares his tale over dinner.  It all begins when Murchison shows a photograph of a beautiful woman, and he asks, ‘does she look trustworthy? It is not an ordinary question and what is the answer you will know at the end of the story.
