A Christmas house party, a sexy lady spy, and an enigmatic earl spell holiday magic. Join New York Times bestselling author Jane Feather in this seductive story of spy and counterspy dueling beneath the mistletoe. While others dance and flirt, Lady Harriet Devere has a secret life, assisting her older brother Nick with his duties as a British spy. When Nick is killed, however, Harriet assumes that her work passing coded messages to the Ministry of War will cease. Instead, she is charged with a vitally important mission: spend Christmas determining if Julius Forsythe, Earl of Marbury, is a double agent for the French. Harriet expects danger, just not to her heart. . . . As the hostess of a holiday house party, she is perfectly placed to closely observe her noble guest--his elegant clothes, his penetrating dark eyes, his virile athletic build. But when passion flames between them, Harriet realizes that only a holiday miracle will allow her to find true love--in the arms of this spy who has come for Christmas.
