I went to the library and checked out Wormwood by Susan Wittig Albert. She has written several mysteries that take place in "Thyme and Seasons", an herb shop in the Texas Hill country. The owner is China Bayles, a former attorney who purchased the store after burning out from her previous job.
Her best friend, Ruby, owns the store next door - a far-out metaphysical store; she is the local psychic. She and China find themselves in all sorts of interesting fixes. Bring in China's sig. other, McQuaid, who is a former law enforcement person, and "Smart Cookie," who is the female chief of police, and there is a medley of characters and fun plots and sub-plots.
All the stories center around solving a murder mystery and herbs. Some of the titles to her books are: Rosemary Remembered, Chili Death, A Dilly of a Death, and the like. The stories are loaded with fun herbal recipes, lore, and history of medicinal healing herbs. She's also an excellent writer; her characters and plots are well-developed - and infused with a sense of good ol' Texas humor.
