Fleetwood is pregnant for the fourth time but has not yet had a surviving child. A midwife she crosses paths with promises to see to it the new baby will live, and as the witchcraft accusations sweeping the North West take on the midwife, Fleetwood stands by her, with the two women's lives entangled irrevocably as the birth and the legendary Lancaster witch trial get closer. For fans of "The Essex Serpent" and "Burial Rites".
