On-Site Evidence tells the story of a crime investigation spanning twenty years.
It begins in 1993, when a boy falls from a high-rise building.
Twenty years later, a bizarre murder takes place in a luxury apartment in downtown Jiang City. Chen Xiaomin, a former homicide detective, discovers the crime scene thanks to her extraordinary sense of smell. The scent there is exactly the same as at an old crime scene she investigated twenty years earlier. And Miao Suyun, the female suspect who was convicted for that old case, has appeared at the new crime scene once again.
The murder of an art academy professor years ago, the killings among wealthy businessmen today, the illicit dealings hidden behind an orphanage... Every clue points to the boy she called "Little Tree." What, exactly, is Miao Suyun, a woman who has kept silent all her life, trying to protect in her own way?
This is a story about how evil passes from one generation to the next, and about how ordinary people save one another when driven to desperation. As the dust of the past is stirred up once more, everyone must face the consequences of their choices.
