A fortune-teller once said that Mingyue was born under an ill omen. Later, she became a coroner for the authorities. Only after her master died did someone from her family arrive with word that they had arranged a marriage for her.
It wasn't until just before the wedding that Mingyue learned her stepmother had betrothed her to the Zhao family's son, who had leprosy.
To escape the marriage meant to bring him good fortune, she hid in the carriage of the junior minister of the Court of Judicial Review.
With her exceptional skill at examining corpses, she helps him solve one strange case after another. But as they unravel the clues, she discovers that her own past is tied to an old miscarriage of justice that once shook the entire court.
