Tea maven Theodosia Browning and her tea sommelier Drayton Conneley are guests at a bird hunt styled in the precise manner of an English shooting party. Theodosia wanders into the neighbour's lavender field where she discovers their host, Reginald Doyle, bleeding to death. As Theodosia investigates, fingers are pointed, secrets are uncovered, Reginald's daughter-in-law goes missing presumed drowned, and Meredith is determined to find answers via a seance.
