"Aunt Dimity and the Witch Village (An Aunt Dimity Mystery, #17)" by Nancy Atherton

Scavenger hunt meets mystery in this book. Finch has a witch in it's history but no one knows what befell her but rumors of a woman with a bloodied hatchet scarring children have been handed down through the centuries. Could they be one and the same, and what is a well known botanical artist doing moving into the center of town with a faded scarp of paper? Lori knows she needs to get to the bottom of this mystery if she hopes to keep her quiet village intact against the invading Bowenists in search of their spiritual leader.
