Indentured servant Patience Martin lives a hard life in 1721 Boston, but things get even harder when her demanding employer is found dead - in a bedroom locked from the inside. Powerful townsmen accuse Patience's friend, Moll Bacon, of being a witch and the murderer, but with her own future in jeopardy, Patience doesn't know how she can help prove Moll's innocence - until she finds a new friend.

Ben Franklin is a clever young printer's apprentice with a fondness for wise aphorisms. Ben risks his own skin to protect Patience, and his cunning and ingenuity are a perfect match for her courage and determination. But will their friendship and teamwork be enough to solve the mystery, clear Moll, and free Patience from a harsh life of servitude?
