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 close to Lucy falls under suspicion. Lucy can’t believe it, but 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 the suspect first-public executions draw a large crowd of spectators, Lucy knows she may never find out what really happened. Unless, that is, she can uncover the truth herself. Determined to do just that, Lucy finds herself venturing out of her expected station and into raucous printers’ shops, secretive gypsy camps, the foul streets of London, and even the bowels of Newgate prison on a trail that might lead her straight into the arms of the killer.
