Nightshade by Susan Wittig Albert
This is the third book in a trilogy within the larger China Bayles mystery series. The other two books are Bleeding Hearts and Spanish Dagger. China is a former attorney who owns an herb shop in the Texas hill country, and does a lot of detecting on the side, often with Ruby, who runs the new age store next to the herb shop, and Sheila, who’s in law enforcement. Mike McQuaid, China’s partner, is a former cop and university professor turned private detective. This trilogy is about a mystery from China’s past; her father’s death in a car crash 16 years earlier, and the introduction of a previously unknown half-brother, Miles. China wasn’t close to her father, who was also a lawyer, and resists the idea that his death wasn’t an accident. This is a good point to jump into an excellent ongoing mystery series. There is a strong sense of place, which makes me want to visit the Texas hill country. The characters develop and change from book to book, and subplots often carry over as well. Susan also writes the Cottage Tales of Beatrix Potter, the Darling Dahlias books, and collaborates with her husband Bill on the Kate and Charles Sheridan mystery series as Robin Paige.
