I enjoy Laura Child's Tea Shop Mysteries, set in Charleston, SC. The owner of this tea shop continually becomes involved in murder and mystery as she operates her shop. However, we learn a great deal about tea in the process.
Some of these mysteries include:
The Teaberry Strangler
Death by Darjeeling
The English Breakfast Murder
Shades of Earl Grey
The Jasmine Moon Mystery
Have you read any of these? Do you have any favorites?
