Morgan Graylocke, the tenth Duke of Tenwick, takes the spy business seriously. Normally relegated to desk work, his brother's recent marriage has given him an opportunity to work in the field. He never imagined his first assignment would throw him in the path of someone as beautiful and intriguing as Philomena St. Gobain. But his delight soon turns to trepidation as he realizes it may not be a coincidence that Phil shows up at all the same locations where Morgan is sent to catch the traitor who is passing off information to the French. Is it possible the woman he is falling for is the very spy he is looking to capture?
