Walter and Artemisia Langston have been blissfully married for three years, but Artemisia has found the role of a small-town vicar's wife somewhat less than fulfilling. Oh, the parishioners are kind and welcoming to her, but unlike her husband, ministering to them just isn't her calling. And then, on Christmas Eve, someone leaves a swaddled newborn in the manger of the vicarage stable. Walter's first suspicion is that it's a terrible prank directed at his wife, but for Artemisia, it's love at first sight.
They can't very well just keep the baby and raise him as their own, however, when they aren't certain where he came from or why. So Walter and Artemisia embark on a mission to find the truth, and not only discover a crime that's been hidden for far too long, but the truest gifts of all: that love multiplies and it's never too late to find a purpose.
