A mystery unwinds in the idyllic English countryside shortly before Christmas Lori can hardly wait for Christmas this year: lean times are over, the cottage Aunt Dimity willed her is more beautiful than ever, her nine-month-old twins, Will and Rob, are thriving, and she and husband Bill have never been happier. Determined to make this Christmas the best ever, Lori embarks on a round of shopping, holly-cutting, angel-cookie making, and more. When fat snow flakes begin drifting down outside of the window, Lori feels all her holiday wishes are about to come true. But the next day, beneath the lilac bushes now covered by freshly fallen snow, Lori makes a disturbing discovery: the body of a mysterious stranger--a tramp--barely alive.  While the nearby village of Finch continues with its seasonal preparations, including rehearsals for the Christmas Eve Nativity play, Lori puts her plans on hold and teams up with Julian Bright--a devilishly attractive Roman Catholic priest--to search out the stranger's identity. Their journey takes them from abandoned World War II airfields to homeless shelters, places where the Christmas star shines dimly, if at all. As Lori unveils the tragic secret that led the stranger to her door, she confronts painful truths about herself and discovers the real meaning of a perfect family Christmas.
