An orphaned girl disguises herself as a coroner's apprentice at the lowest level of Dali Temple, just to use her widow's house as an old file to investigate her father's unjust case.
She has a pair of hands that can "touch the last seven seconds of the deceased" - but every time the resonance takes effect, she must hold the hand of the cold-faced Dali Temple minister.
He thought she wanted to climb into bed, and she thought he knew about it but didn't report it.
