For Lucy Campion, a seventeenth-century English chambermaid serving in the household of the local magistrate, life is an endless repetition of polishing pewter, emptying chamber pots, and dealing with other household chores until a fellow servant is ruthlessly killed, and someone she loves is wrongly arrested for the crime. In a time where the accused are presumed guilty until proven innocent, lawyers aren't permitted to defend their clients, and--if the plague doesn't kill them first--public executions draw a large crowd of spectators, Lucy knows she may never see this person alive again. Unless, that is, she can identify the true murderer.
