Michael Rafferty is an agent for the Crown, on the trail of a conspirator championing Irish independence through acts of violence. The trail leads to Washington, D.C., where Rafferty must assume the role of a diplomat in order to set a trap for the villain. To complete the pretense, he'll need to transform his coarse image and find someone to portray his wife. Lady Arianne Chambers, sister to a duke and well versed in high-society circles, reluctantly agrees to assist Rafferty's charade. She'll teach him the finer points of being a gentleman, but she has no desire for a husband. Yet the honorable and passionate man hidden beneath the rough edges finds his way into her heart. Can she trust her secrets—and her future—to such a seductive rogue?
