While out on a walk in the hills during a visit to her relatives in Derbyshire, Jane finds a terribly mutilated body. It turns out to be Tess Arnold, a stillroom maid at a local estate known for her skill as an herbalist. Was Tess suspected of witchcraft? Was she thought to be traitor to the secret rites of the Freemasons? What was her relationship with the Duke's family. Was the killing the work of a madman? When the wrong person is accused of murder, Jane Austen becomes an innocent victim's only hope in a fiendishly clever and breathlessly diverting mystery.
