Aunt Dimity's Christmas

Description for AUNT DIMITY'S CHRISTMAS by Nancy Atherton:

Lori Shepherd can hardly wait to celebrate Christmas this year with her husband, Bill, and their twin sons in the beautiful cottage willed to her by Aunt Dimity. But then Lori makes a disturbing discovery beneath the cottage's snow-covered lilac bushes--the body of a mysterious stranger, barely alive. Lori puts her plans on hold to team up with Julian Bright--a devilishly attractive Roman Catholic priest--and seek out the tramp's identity. Their adventure takes Lori and Julian from abandoned World War II airfields to homeless shelters--places where the Christmas star shines dimly, if at all. With Aunt Dimity's ghostly guidance, Lori unveils the tragic secret that led the stranger to her door, and must confront painful truths about herself and the true meaning of a perfect family Christmas.
