A Plain Vanilla Murder

China and Ruby Wilcox are presenting their annual ''Not Just Plain Vanilla Workshop,'' always a huge hit with customers at Thyme & Seasons Herb Shop. But someone involved with the workshop is driven by a deadly motive, and China soon finds herself teaming up with the very pregnant Pecan Springs police chief Sheila Dawson to solve a vanilla-flavored murder. Sheila, happy to get out from behind the chief's desk, is investigating the death of a botany professor, a prominent researcher specializing in vanilla orchids. China is trying to help a longtime friend: the dead professor's ex-wife and a prime suspect in his murder. However, there's no shortage of other suspects: a betrayed lover, a disgruntled graduate student, jealous colleagues, and a gang of orchid smugglers. But the lethal roots of this mystery reach back into the dark tropical jungles of Mexico, where the vanilla vine was first cultivated. At stake is a lucrative plant patent, an orchid that is extinct in the wild, and the life of an innocent little girl.
