Lesson One: Don't forget to tell your wife you're a spy... An absentee husband is one thing, but a dead husband is too much for Lady Mariana Asquith to ignore. When she travels to Paris to search for the body of the wastrel who broke her heart, she finds him-alive at the Opera and still far too attractive for her comfort. But not everything is what it seems with her husband... Lesson Two: Don't let your husband seduce you... Nick has sacrificed everything to protect King and Country-including his marriage. But after ten years of staying away from the woman he loves, he can't quite make himself drive Mariana away. He longs to be done with the lies and spies-but there's one last job, with a seductive partner at his side.... Lesson Three: Whatever you do, don't fall in love-again. As they work together to save the French government from powerful adversaries, Nick must teach his wife how to be a spy, starting with how to seduce a dangerous stranger. Mariana already has some experience with dangerous men thanks to Nick, and she has her own lessons to teach him-like how passion, love, and trust just might save the day.
