While Lady Violet Belmaine is busy sorting out the odd turns her life has recently taken, Hugh St. Sevier repairs to his Kent estate in hopes of embarking on the placid life of a rural physician. Alas, for St. Sevier, the village of St. Ivo has more secrets than it has pots of heartease, and the good doctor will once again find himself the target of rumors and threats.Somebody is rigging St. Ivo's hound races, setting neighbor against neighbor, and turning what should be a friendly entertainment into an occasion for brawling. As an expert on medicinal herbs and soporifics, St. Sevier comes under suspicion. St. Ivo badly needs a physician, and the village also needs somebody to unravel the intrigues that are tearing it apart. St. Sevier can't get to the bottom of the mystery on his own, but help--in the persons of Lady Violet and Sebastian MacHeath, is on the way!
