“The day the wanted posters branding her a prince's poisoner covered every city gate, Su Tang's last glimpse before plunging off the cliff was a red robe drifting through the rain. When she opens her eyes again, memories of her former life as a modern forensic doctor slice into her mind: the shape of lividity on a corpse can speak, half a grain of rice in the stomach can identify a killer, and even rust in the seams between bones cries out for justice! Wrapped in bloodstained clothes, she crouches beside the latest corpse of a woman in red and runs her fingers over the puncture wound at the back of the dead woman's neck. ‘This isn't a ghost taking lives. Someone is using a method from twenty years ago to set me up.’
The newly appointed head of the Court of Judicial Review, Pei Yan, arrives carrying a lamp, his snow-white official robes damp with night dew. ‘A coroner of low birth thinks she can investigate cases?’
Su Tang slaps the autopsy report down at his boots. Blood spreads across it, blurring into the character for ‘trap.’ ‘Why don't you take a look, Lord Pei? Doesn't the gold leaf under this corpse's fingernails look just like the secret letter of treason you're searching for?’
When modern forensic investigation meets bizarre cases from ancient times, a female coroner trampled into the mud must use this corpse to clear a twenty-year-old injustice, including the truth about herself: she is the former emperor's blood relative, lost among the common people.”
